Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other regions on the planet. We conduct the largest meta-analysis to date of phenological drivers and trends among southern hemisphere species, assessing 1208 long-term datasets from 89 studies on 347 species. Data were mostly from Australasia (Australia and New Zealand), South America and the Antarctic/subantarctic, and focused primarily on plants and birds. This meta-analysis shows an advance in the timing of spring events (with a strong Australian data bias), although substantial differences in trends were apparent among taxonomic groups and regions. When only statistically significant trends were considered, 82% of terrestrial datasets and 42% of marine datasets demonstrated an advance in phenology. Temperature was most frequently identified as the primary driver of phenological changes; however, in many studies it was the only climate variable considered. When precipitation was examined, it often played a key role but, in contrast with temperature, the direction of phenological shifts in response to precipitation variation was difficult to predict <italic>a priori</italic>. We discuss how phenological information can inform the adaptive capacity of species, their resilience, and constraints on autonomous adaptation. We also highlight serious weaknesses in past and current data collection and analyses at large regional scales (with very few studies in the tropics or from Africa) and dramatic taxonomic biases. If accurate predictions regarding the general effects of climate change on the biology of organisms are to be made, data collection policies focussing on targeting data-deficient regions and taxa need to be financially and logistically supported.</p></div></front><back><div1 type="bibliography"><listBibl><biblStruct></biblStruct><biblStruct><analytic><author><name sortKey="M Ller, Ap" uniqKey="M

Given regional differences in climate change, shifts in phenology will not be uniform across the globe, and conclusions drawn from temperate systems in the northern hemisphere might not be applicable to other regions on the planet. We conduct the largest meta-analysis to date of phenological drivers and trends among southern hemisphere species, assessing 1208 long-term datasets from 89 studies on 347 species. Data were mostly from Australasia (Australia and New Zealand), South America and the Antarctic/subantarctic, and focused primarily on plants and birds. This meta-analysis shows an advance in the timing of spring events (with a strong Australian data bias), although substantial differences in trends were apparent among taxonomic groups and regions. When only statistically significant trends were considered, 82% of terrestrial datasets and 42% of marine datasets demonstrated an advance in phenology. Temperature was most frequently identified as the primary driver of phenological changes; however, in many studies it was the only climate variable considered. When precipitation was examined, it often played a key role but, in contrast with temperature, the direction of phenological shifts in response to precipitation variation was difficult to predict <italic>a priori</italic>. We discuss how phenological information can inform the adaptive capacity of species, their resilience, and constraints on autonomous adaptation. We also highlight serious weaknesses in past and current data collection and analyses at large regional scales (with very few studies in the tropics or from Africa) and dramatic taxonomic biases. If accurate predictions regarding the general effects of climate change on the biology of organisms are to be made, data collection policies focussing on targeting data-deficient regions and taxa need to be financially and logistically supported.</p></abstract><funding-group><funding-statement>This work is based upon research supported by the National Research Foundation of South Africa to RA, PB, and RJMC, and by the Applied Centre for Climate and Earth System Science to RA.

Population-limiting factors are closely linked to seasonal or interannual phenological events, and shifts in phenology can affect ecosystems through changes in ecological interactions such as predator-prey and plant-pollinator dynamics <xref ref-type="bibr" rid="pone.0075514-Cushing1">[3]</xref>–<xref ref-type="bibr" rid="pone.0075514-EncinasViso1">[6]</xref> and the epidemiology of infectious diseases <xref ref-type="bibr" rid="pone.0075514-Harvell1">[7]</xref>, <xref ref-type="bibr" rid="pone.0075514-deLaRocque1">[8]</xref>. Warming is hypothesised to lead to earlier spring events such as breeding onset, timing of flowering, breeding migration; delayed autumn events such as leaf fall, non-breeding migration; and a longer summer growing season <xref ref-type="bibr" rid="pone.0075514-Parmesan1">[9]</xref>. Changing phenologies will contribute to shifts in species distributions, population viability and reproductive successes <xref ref-type="bibr" rid="pone.0075514-Schaper1">[10]</xref>, <xref ref-type="bibr" rid="pone.0075514-Mair1">[11]</xref> and in turn will affect climate via biogeochemical processes and the physical properties of the biosphere <xref ref-type="bibr" rid="pone.0075514-Peuelas1">[12]</xref>. As such, phenological changes will have profound consequences for human societies and economies, including agricultural production <xref ref-type="bibr" rid="pone.0075514-Stokes1">[13]</xref>, fisheries production <xref ref-type="bibr" rid="pone.0075514-MacNeil1">[14]</xref> and human health <xref ref-type="bibr" rid="pone.0075514-Ziello1">[15]</xref>.</p><p>Estimates for advancement of spring phenological events from meta-analyses range from 2.8±0.35 days/decade on land <xref ref-type="bibr" rid="pone.0075514-Parmesan1">[9]</xref>, <xref ref-type="bibr" rid="pone.0075514-Parmesan2">[16]</xref>, <xref ref-type="bibr" rid="pone.0075514-Root1">[17]</xref> to 4.4±0.7 days/decade in the oceans <xref ref-type="bibr" rid="pone.0075514-Poloczanska1">[18]</xref>. Substantial differences in the strengths of responses have been observed across taxonomic groups; datasets demonstrating significant trends showed that spring phenological events of herbs and grasses have advanced 1.1±0.16 days/decade, compared with 7.6±3.09 days/decade for amphibians and 3.7±0.7 days/decade for birds and 6.3±1.6 days/decade for marine phytoplankton <xref ref-type="bibr" rid="pone.0075514-Parmesan1">[9]</xref>, <xref ref-type="bibr" rid="pone.0075514-Poloczanska1">[18]</xref>. However, these meta-analyses are presently biased heavily to northern hemisphere temperate regions.</p><p>Since the beginning of the 20<sup>th</sup> century the northern hemisphere has warmed faster than the southern hemisphere, with the rates of warming three times higher over land than ocean <xref ref-type="bibr" rid="pone.0075514-IPCC1">[19]</xref>. Further, comparisons of the magnitude of projected changes in temperature and precipitation, relative to the 20<sup>th</sup> century mean and variability, consistently identify several low latitude and southern hemisphere locations as being amongst the first to experience novel or extreme conditions in the 21<sup>st</sup> century <xref ref-type="bibr" rid="pone.0075514-Beaumont1">[20]</xref>, <xref ref-type="bibr" rid="pone.0075514-Diffenbaugh1">[21]</xref>. These include parts of the Amazon, Indonesia, southern Africa and Madagascar.</p><p>Given regional differences in climate change, and the disparities in projected climate changes between the northern and southern hemispheres (e.g. <xref ref-type="bibr" rid="pone.0075514-Chou1">[22]</xref>, <xref ref-type="bibr" rid="pone.0075514-Giorgi1">[23]</xref>), it is likely that phenological shifts will not be uniform across the globe and that conclusions drawn from northern hemisphere temperate terrestrial and marine systems might not always apply to other regions, particularly so in the southern hemisphere. More than 80% of the southern hemisphere is ocean, which stores more heat than land and promotes different weather systems compared to the land-dominated northern hemisphere. For example, temperature variations are smaller and there is less extreme seasonal variation in the southern hemisphere, allowing some species to reproduce year round, particularly at lower latitudes <xref ref-type="bibr" rid="pone.0075514-Morellato1">[24]</xref>, <xref ref-type="bibr" rid="pone.0075514-Morellato2">[25]</xref>. Instead of a clear period of biological dormancy, such as that enforced by low winter temperature at high northern latitudes, phenological cycles in the south are often less distinct. For example, in the high latitude oceans, low winter temperatures, sea ice extent and day length interact to produce prominent spring blooms of phytoplankton in the northern hemisphere, whereas blooms are less pronounced and of smaller magnitude in the southern hemisphere <xref ref-type="bibr" rid="pone.0075514-Yoder1">[26]</xref>. This means that continuous monitoring in the southern hemisphere may be more critical, and sophisticated statistical tools for interpretation will be required (e.g. <xref ref-type="bibr" rid="pone.0075514-Altwegg1">[27]</xref>, <xref ref-type="bibr" rid="pone.0075514-Staggemeier1">[28]</xref>). We might also predict the phenologies of species living outside European and North American temperate regions to show relatively less response to temperature fluctuations, but more to factors such as rainfall. For example, in many tropical systems where the alternation between dry and wet seasons is pronounced, the intensity and length of drier periods may drive the start of flowering and leafing seasons <xref ref-type="bibr" rid="pone.0075514-Morellato1">[24]</xref>.</p><p>Given the climatic and biological differences of the two hemispheres and the paucity of southern hemisphere examples in previous phenological meta-analyses, our study aimed to collate all published accounts of recent phenological trends reported for southern hemisphere terrestrial, freshwater and marine species.

A candidate list of papers was checked for evidence of datasets or analyses that fitted our criteria (see below). Additional papers were added based on expert knowledge and through direct contact with specialists and researchers working with biological data and considering recent phenological reviews <xref ref-type="bibr" rid="pone.0075514-Morellato1">[24]</xref>, <xref ref-type="bibr" rid="pone.0075514-Keatley1">[29]</xref>, <xref ref-type="bibr" rid="pone.0075514-Chambers1">[30]</xref>.</p><p>Studies were included in the database if they had at least 10 years of data and ended post-1990, thereby being coincident with the most recent climate changes. Data meeting the criteria were available from 1852 to 2011 (mean = 32 years, median = 25 years) with the bulk of the data from the 1970s–2000s. Long-term data sets ending before 1990 were also noted (but not analysed) because they are likely to provide useful baseline data for future comparative studies (see <xref ref-type="supplementary-material" rid="pone.0075514.s001">Appendix S1</xref> in Supporting Information). The potential influence(s) of the lengths of data series and the starting years on the trends detected and conclusions is discussed in <xref ref-type="supplementary-material" rid="pone.0075514.s004">Appendix S4</xref>.</p><p>From each study, we extracted the following information for each species: study location, years of the study, species name, phenophases (e.g. breeding, migration, flowering) recorded, phenological trend (in days/decade), assessed or inferred climatic or non-climatic drivers of phenological variability or change (where available) and statistical significance (where available). Each phenological observation was classified as earlier, later or no change (trend not statistically significant).</p><p>In addition to the analyses presented in <xref ref-type="table" rid="pone-0075514-t001">Tables 1</xref>, <xref ref-type="table" rid="pone-0075514-t002">2</xref>, and <xref ref-type="table" rid="pone-0075514-t003">3</xref>, which were based on all available data (up to 1208 time series), we formally analysed mean trends across time series which reported the trend together with an estimate of precision (standard error) using meta-analysis. Unfortunately, this information was reported for only 397 of the time series, of which 390 were from Australia. We therefore restricted the formal meta-analysis to Australian time series. Of these 390 times series, 164 measured trends in the reproductive phenology of the common grapevine, <italic>Vitis vinifera</italic> (119 trends were for harvest, 45 for maturity and three for flowering) and three for other plant species. For comparison, based on the full data set, information on grape phenology consisted of 176 of a total of 480 plant time series (see <xref ref-type="supplementary-material" rid="pone.0075514.s005">Appendix S5</xref>). A total of 223 of the 390 times series measured trends in breeding phenology of birds, which were more taxonomically diverse, covering 66 species. Variation thus enters this data set at three levels: among-species (within plants and birds, respectively), among-studies within species, and the error associated with estimating each trend. To account for this hierarchical structure, we adopted a hierarchical Bayesian approach similar to that used by McCarthy and Masters <xref ref-type="bibr" rid="pone.0075514-McCarthy1">[31]</xref> to estimate the mean trend in phenology in birds and plants, and to quantify the uncertainty around these mean estimates. The model was a mixed-effects model with estimated trends as the response. Instead of treating these estimates as fixed data, we treated them as coming from a normal distribution with the mean and variance as reported in the original publications. Taxon (bird vs plant) was a fixed effect and species was treated as a random effect. The length of the time series used in this analysis varied from 10 to 115 years (median 27) and we included the logarithm of time series length as a further covariate in the analysis, as the length of the time series can influence the resultant trend estimate (e.g. <xref ref-type="bibr" rid="pone.0075514-Sparks1">[32]</xref>, but see <xref ref-type="supplementary-material" rid="pone.0075514.s004">Appendix S4</xref>).

However, temperature was the only variable considered amongst 27% of papers. A low number of studies included potential non-climatic drivers, such as observational and management changes. For species foraging in marine environments, the most frequently identified drivers of phenological change were sea ice extent (in the Antarctic), broad-scale indices such as the El Niño-Southern Oscillation phenomenon (ENSO) and the Southern Oscillation Index (SOI), and sea surface temperature. For freshwater species, rainfall and air temperature were the most frequently identified drivers. Similarly, among terrestrial species, air temperature was cited as the primary driver of phenology in 52% of cases, whereas 26% found rainfall to be the primary driver.

For the Antarctic/subantarctic region, sea-ice extent was most often cited as the primary variable (30% of cases), with ENSO (12%) and sea surface temperature (8%), likely covariates, also playing an important role. In contrast, rainfall was reported as a primary driver in southern Africa (23% of cases) with air temperature and ENSO also noted as playing an important role (18% and 14% of cases, respectively). Similarly, for tropical South America rainfall was identified as the main driver, especially in seasonal environments, with day length also important in non-seasonal regions, and temperature becoming increasingly important at higher latitudes. Conversely, for Australasia, air temperature was more often considered the primary driver (40% of cases), followed by rainfall (13%).</p><p>Trends towards earlier phenological events were most often associated with increasing air temperatures (73% of all earlier events considered air temperature as a primary climate driver) (<xref ref-type="table" rid="pone-0075514-t003">Table 3</xref>). In fact, 39% of datasets that considered air temperature as one of the primary drivers observed earlier phenologies, compared to 5% observing later phenologies. For datasets where rainfall was identified as the primary climate driver there was a near-even mix of earlier and later events. Where sea-ice extent was noted as a primary driver, a greater number of later events were observed than earlier ones (6 of 15 compared to 1 of 15, respectively). This was also the case for sea surface temperature/sea levels (2 of 16 earlier compared to 7 of 16 later).</p></sec></sec><sec id="s4"><title>Discussion</title><p>Based on 1208 datasets from 347 species, this is the most comprehensive review of phenological trends and their associated drivers among southern hemisphere species.

We found in many cases, changes were faster than those reported from predominately northern hemisphere regions. We also found that precipitation frequently appears to play a key role and, in contrast with temperature, the direction of phenological shifts in response to altered precipitation regimes is difficult to predict <italic>a priori</italic>. This is due, in part, to greater certainty in direction of future change in temperature than precipitation <xref ref-type="bibr" rid="pone.0075514-IPCC1">[19]</xref>, <xref ref-type="bibr" rid="pone.0075514-IPCC2">[37]</xref>.</p><sec id="s4a"><title>Regional and Taxon-specific Biases in Data Availability</title><p>It is clear that serious data deficiencies exist in southern hemisphere phenological datasets, with continental-scale knowledge gaps in relating phenology to climate variables and change. This is particularly evident when comparing the number of available datasets for the three main land masses. Despite Australasia being a fraction of the size of Africa or South America, more than 80% of the available datasets originated there, as did almost all of the phenology trend analyses (Australia/New Zealand versus Africa/South America; 898 versus 16; <xref ref-type="table" rid="pone-0075514-t001">Table 1</xref>). The situation for the Pacific nations, which are rich in island endemic species and may face unique challenges during climate change (e.g. extreme barriers to adaptive distribution shifts), is even more dramatic with only a single bird dataset found (<xref ref-type="table" rid="pone-0075514-t001">Table 1</xref>).</p><p>When the taxa represented in these datasets are examined, extreme biases are also evident. Plants and birds comprise around 85% of datasets, arthropods 13%, and mammals, reptiles and amphibians each contributing less than 1%. But even these figures are misleading as to the nature of biases. Although 480 plant datasets were recorded, phenological trends were predominantly from Australia/New Zealand, only four from Africa and none from the other regions, and 60% of these of studies were on commercial viticulture crops. All 161 arthropod studies were from 68 species of Australian butterflies. The fact that there are only three studies on reptiles, four on marine mammals, and none on amphibians suggests that our predictive capacity of how phenology might change over time and in response to climate drivers for a huge range of taxa will essentially be guesswork for many years to come.</p></sec><sec id="s4b"><title>Regional Differences in Species Responses, Timing of Events, and Climate Drivers</title><p>Environmental or climate change drivers vary regionally, and may result in different biological responses <xref ref-type="bibr" rid="pone.0075514-IPCC2">[37]</xref>. For example, large areas of cooling have been observed in the Southern Ocean during the past few decades, whereas West Antarctica and several subantarctic islands have warmed more rapidly than other parts of this continent (e.g. <xref ref-type="bibr" rid="pone.0075514-Turner1">[38]</xref>, <xref ref-type="bibr" rid="pone.0075514-Vaughan1">[39]</xref>). Similarly, terrestrial biomes have warmed more rapidly than marine biomes <xref ref-type="bibr" rid="pone.0075514-IPCC1">[19]</xref>. Analysis of observed seasonal shifts in temperature over 1960–2009 showed high variability between hemispheres and within regions <xref ref-type="bibr" rid="pone.0075514-Burrows1">[40]</xref>. Because of the smaller seasonal thermal variations in the southern hemisphere, spring temperatures were recorded earlier by 2.5 days/decade over oceans and 2.2 days/decade over land, whereas in the northern hemisphere, the corresponding values are 2.1 and 1.5 days/decade, respectively. In many cases, changes in observed phenology are faster than or lag shifts in seasonal temperatures, suggesting the potential for decoupling of trophic and other interactions within ecosystems.</p><p>Phenological trends among populations of a widespread species may differ in magnitude, depending on local and regional changes in climate. This is demonstrated among populations of Dollarbirds <italic>Eurystomus orientalis,</italic> and Common Koels <italic>Eudynamys scolopacea,</italic> which have significantly advanced their arrival at breeding grounds in south-east Australia but not in more northerly regions <xref ref-type="bibr" rid="pone.0075514-Chambers2">[41]</xref>. Similarly in south-east Australia, the first flight date of inland populations of the butterfly, <italic>Heteronympha penelope</italic>, has been significantly delayed since 1950, while no significant trend has occurred amongst coastal populations <xref ref-type="bibr" rid="pone.0075514-McClellan1">[42]</xref>. In addition, several studies have demonstrated that fish populations located at the limits of their geographical distribution are more sensitive to environmental variability than core populations (e.g. <xref ref-type="bibr" rid="pone.0075514-Brunel1">[43]</xref>). This suggests that higher latitude species, which are often at their geographical and ecological limits, may respond more strongly to climate change.</p><p>Advances in the timing of breeding have been reported for seabirds in the Arctic due to increasing spring temperatures and earlier access to nesting sites and food availability <xref ref-type="bibr" rid="pone.0075514-Dickey1">[44]</xref>, <xref ref-type="bibr" rid="pone.0075514-Moe1">[45]</xref>. In Antarctica, however, studies report both delayed breeding among seabirds <xref ref-type="bibr" rid="pone.0075514-Barbraud1">[33]</xref>, <xref ref-type="bibr" rid="pone.0075514-Hindell1">[46]</xref>, <xref ref-type="bibr" rid="pone.0075514-Chambers3">[47]</xref> and advances <xref ref-type="bibr" rid="pone.0075514-Hindell1">[46]</xref>, <xref ref-type="bibr" rid="pone.0075514-Lynch1">[48]</xref>. However, both delays and advances are generally consistent with expectations under climate change when local and regional climatic and oceanographic changes together with seabird life histories are taken into account <xref ref-type="bibr" rid="pone.0075514-Barbraud1">[33]</xref>. Marine food webs near Antarctica are heavily affected by variations in the extent of sea ice, which is in turn influenced by changes in salinity, sea temperature, winds, and ocean circulation <xref ref-type="bibr" rid="pone.0075514-Barbraud1">[33]</xref>, <xref ref-type="bibr" rid="pone.0075514-Smetacek1">[49]</xref>. Increasing sea surface temperature and decreasing sea ice extent are associated with reductions in Antarctic Krill <italic>Euphausia superba</italic> and other marine organisms, and may be responsible for delayed breeding in seabirds <xref ref-type="bibr" rid="pone.0075514-Barbraud1">[33]</xref>, <xref ref-type="bibr" rid="pone.0075514-Barbraud2">[50]</xref>. At a regional scale, if separate populations of migrating seabirds use different over-wintering areas, climatic differences between these areas during the pre-breeding stage may contribute to divergent trends in the timing of breeding, for example, through regional differences in food quality and peak availability. Similarly, individuals that occur (or breed) at the edge of the species’ geographical distribution, where they are likely to be at the limit of their physiological tolerance, may be more likely to undergo phenological adjustments (or indeed disperse) than individuals closer to the core of their distribution (e.g. Gentoo Penguins <italic>Pygoscelis papua</italic>, <xref ref-type="bibr" rid="pone.0075514-Lescrol1">[51]</xref>). This could partly explain why climate change may affect Arctic and Antarctic species differently: the lower extent of land cover in the southern hemisphere may more tightly constrain the responses of populations, compared with those in the northern hemisphere.</p><p>Individuals and different species within the same biome or region may vary in their response to climate change because of the scale at which they sample their environments (e.g. through predation) and use environmental cues <xref ref-type="bibr" rid="pone.0075514-Frederiksen1">[52]</xref>. In the Southern Ocean, the crustacean genus <italic>Euphausia</italic> (krill) plays a critical role in the food web of the Scotia Sea, supporting many top predators <xref ref-type="bibr" rid="pone.0075514-Murphy1">[53]</xref>, whereas in the Southern Indian Ocean the fish family Myctophidae dominates the food web <xref ref-type="bibr" rid="pone.0075514-Pakhomov1">[54]</xref>. Yet, there are top predator species common to both biomes. Consequently, this spatial variability at lower trophic levels coupled with specific temperature tolerances may result in variable impacts of regional warming, with different consequences for upper trophic levels depending upon the regional food webs in which they reside (e.g. <xref ref-type="bibr" rid="pone.0075514-Mintenbeck1">[55]</xref>).</p><p>Differences in regional phenological responses may also result from variation in food webs and associated environmental drivers. Top predators (such as seabirds) integrate the effects of environmental or climatic change in the lower trophic levels over a range of temporal and spatial scales, and regional differences in food webs may mean that top predators are affected differently in different regions. Similarly, initiation of breeding, and other phenological parameters, may vary depending on the availability of resources before the breeding season.

First, most of the studies analysed in this review that attempted to relate phenology to specific drivers focused on one climate variable only, most commonly air or sea surface temperature. Mismatch among the temporal and spatial scales of biological and climatic datasets and lack of process-understanding can reduce ability to obtain reliable inferences <xref ref-type="bibr" rid="pone.0075514-Brown1">[99]</xref>. The focus on temperature limits our understanding of the explanatory power of other variables, such as precipitation or sea ice extent.</p><p>Second, the scarcity of long-term datasets in some southern regions, in particular in Africa, Pacific nations and South America, combined with the potentially strong (but poorly understood) effects of ENSO may bias analyses towards identifying ENSO fluctuations as phenological drivers. Rainfall and temperature patterns in tropical and southern hemisphere regions are strongly influenced by ENSO, which occurs in pseudo-cycles of two to seven years <xref ref-type="bibr" rid="pone.0075514-Latif1">[57]</xref>. As such, ENSO events have substantial impacts on ecosystems, and drive pulses of primary productivity in tropical, arid and semi-arid southern regions <xref ref-type="bibr" rid="pone.0075514-Potter1">[58]</xref>, <xref ref-type="bibr" rid="pone.0075514-Holmgren1">[59]</xref>. Third, given that precipitation frequently drives species life cycles, focusing on a) temperature only, and b) identifying only linear trends in phenology may mean that important non-linear responses of populations to precipitation (and temperature) variability are missed.</p><p>Finally, phenological data sets are frequently from extensively modified and perturbed ecosystems. Less disturbed ecosystems may be more resilient <xref ref-type="bibr" rid="pone.0075514-Halpern1">[60]</xref>, and analyses and predictions derived from them may be more robust. The preservation of the remaining minimally modified ecosystems is therefore critical, both for climate adaptation <xref ref-type="bibr" rid="pone.0075514-Woehler1">[61]</xref> and for analyses investigating impacts of climate change.</p></sec><sec id="s4d"><title>Non-climatic Drivers of Change</title><p>Although non-climatic factors, such as phylogenetic constraints <xref ref-type="bibr" rid="pone.0075514-Davis1">[62]</xref>, <xref ref-type="bibr" rid="pone.0075514-Kochmer1">[63]</xref> and competition <xref ref-type="bibr" rid="pone.0075514-Aizen1">[64]</xref>, <xref ref-type="bibr" rid="pone.0075514-Yang1">[65]</xref>, can be important drivers of phenological trends, few studies identify or discuss the potential for non-climatic drivers to fully, or even partially, explain trends (but see <xref ref-type="bibr" rid="pone.0075514-Staggemeier2">[66]</xref>).

Empirical information on the evolution of phenotypic plasticity in the southern hemisphere is very scarce, highlighting the need for longitudinal and inter-specific comparative studies. For species with relatively long generation times, phenological changes through micro-evolutionary processes may be too slow to track the pace of projected climate change <xref ref-type="bibr" rid="pone.0075514-Visser1">[75]</xref>.</p><p>Phenological flexibility may provide an important buffer against negative impacts of environmental change, and a useful indicator for identifying species capable of adapting. The ability of Antarctic/subantarctic species to alter their phenology in response to climate variability and change is poorly known. However, many seabirds and marine mammals are heavily constrained in their phenology by the short time period at high latitudes with favourable conditions for breeding. For migratory seabirds in more southerly regions, the timing of breeding is likely to be determined by photoperiod modulated by other factors, such as sea surface temperatures, rainfall and food availability. Because photoperiod is not affected by climate change, it is not necessarily a reliable clue of peak/optimal breeding conditions.</p><p>Penguins are a taxon that dominates reports of phenological shifts in the Antarctic (e.g. <xref ref-type="bibr" rid="pone.0075514-Ainley1">[76]</xref>). Substantial differences occur among these species in their ability to adapt via phenological change. As an example, Adélie Penguins <italic>P. adeliae</italic> at the South Orkney Islands normally commence breeding earlier than Gentoo Penguins, except in years with mild winters when Gentoo Penguins breed first <xref ref-type="bibr" rid="pone.0075514-Forcada1">[77]</xref>. The more limited flexibility in the phenology of Adélie Penguins may result from other adaptations that enable the species to breed successfully at higher latitudes than Gentoo Penguins <xref ref-type="bibr" rid="pone.0075514-Forcada1">[77]</xref>. In addition, clutch initiation dates in the non-dispersive Gentoo Penguin have adjusted more rapidly than in the dispersive Adélie or Chinstrap Penguins <italic>P. antarctica</italic><xref ref-type="bibr" rid="pone.0075514-Lynch1">[48]</xref>, <xref ref-type="bibr" rid="pone.0075514-Lescrol1">[51]</xref>, <xref ref-type="bibr" rid="pone.0075514-Hinke1">[78]</xref>. However, data suggest that in general, penguins may have a limited ability to adapt phenologically to climate change, and have so far responded primarily via dispersal (e.g. <xref ref-type="bibr" rid="pone.0075514-Emslie1">[79]</xref>, <xref ref-type="bibr" rid="pone.0075514-Petry1">[80]</xref>).</p><p>Limited availability of suitable breeding grounds on oceanic islands, as well as high levels of philopatry, may reduce the ability of seabirds and marine mammals to respond via dispersal <xref ref-type="bibr" rid="pone.0075514-Forcada1">[77]</xref>, <xref ref-type="bibr" rid="pone.0075514-Emslie1">[79]</xref>. Island species are often sedentary, with a reduced capacity for range shifts, and lower genetic variability that may limit evolutionary rescue effects if phenotypic plasticity cannot operate. These characteristics potentially make island species more vulnerable to rapid climate shifts (e.g. the Mauritius Kestrel <italic>Falco punctatus</italic><xref ref-type="bibr" rid="pone.0075514-Senapathi1">[81]</xref>). However, some highly migratory bird species, such as the South Polar Skua <italic>Catharacta maccormicki</italic> show a wide variation in their migration behaviours, even within a single breeding population, indicating the potential for buffering in some species <xref ref-type="bibr" rid="pone.0075514-Kopp1">[82]</xref>.</p><p>Several studies from the northern hemisphere provide evidence that the tendency of species to alter their migration and breeding phenology over the past few decades is correlated with population trends <xref ref-type="bibr" rid="pone.0075514-Mller1">[2]</xref>, <xref ref-type="bibr" rid="pone.0075514-Salido1">[83]</xref>. Examples of correlations between phenological responses and demography, however, are lacking in the southern hemisphere studies reviewed here, as are similar investigations of correlations between life history characteristics and phenological change. However, recently published studies from the northern hemisphere provide useful pointers for future investigations. Amongst passerines in France, for example, species with the broadest ecological and thermal niches, shortest mean migration distances and largest brains were most able to adjust their phenology, indicating that specialists and long distance migrants are more at risk <xref ref-type="bibr" rid="pone.0075514-Moussus1">[84]</xref>.

However, few studies provided data on changes in the phenological synchrony of interacting species, although several speculate as to the potential impacts of such changes and relationships. For plants and their seed predators in New Zealand, it is predicted that warming will eventually result in annual flowering of mast seeding species, with subsequent increases in insect and mammalian seed predation, changes in the population regulation of seed predators, and a decrease in predator satiation leading to decreasing reproductive output in the plants <xref ref-type="bibr" rid="pone.0075514-McKone1">[87]</xref>, <xref ref-type="bibr" rid="pone.0075514-Schauber1">[88]</xref>.

Similarly, phenological flexibility among Antarctic fur seals <italic>Arctocephalus gazella</italic> is likely to be limited because females are constrained by the relatively long interval (∼16 months) between conception and weaning of their pup.

For example, the datasets incorporated in this study differ in terms of observer effort and biases and the use of a variety of different measures of phenological timing, both of which are beyond the control of this review. The use of phenological measures based on first or last events has been argued to be less than ideal <xref ref-type="bibr" rid="pone.0075514-Moussus2">[110]</xref>, particularly in relation to the potential influence of population size, outliers and observer effort and ability <xref ref-type="bibr" rid="pone.0075514-Lindn1">[111]</xref>. However, these were the most common observations recorded (<xref ref-type="supplementary-material" rid="pone.0075514.s006">Appendix S6</xref>), most likely due to their ease of collection. Previous studies have found that the use of measures such as first arrival date reflect the widely-observed advancement of spring migration <xref ref-type="bibr" rid="pone.0075514-MillerRushing2">[112]</xref> and phenological first (and last) measures remain frequently-used, particularly so for migration studies assessing standardised datasets (e.g. <xref ref-type="bibr" rid="pone.0075514-Sparks2">[113]</xref>, <xref ref-type="bibr" rid="pone.0075514-Kobori1">[114]</xref>, <xref ref-type="bibr" rid="pone.0075514-Sokolov1">[115]</xref>, <xref ref-type="bibr" rid="pone.0075514-Vegvari1">[116]</xref>).</p><p>In conclusion, the current evidence of climate change impacts on phenological patterns for many regions in the southern hemisphere is sparse, especially in South America, small island nations and Africa. Research efforts and policies are urgently needed to develop longer-term time series and more in-depth analyses. Despite locating more than 1000 datasets reviewed here, our understanding and capacity to predict phenological responses remains patchy and constrained. For a few species and communities we can identify some patterns, but we generally are unable to describe spatial (extents of change) and temporal (rates of change) responses. While we can make broad predictions and provide preliminary generalisations, our constrained understanding of the complexity of ecosystem relationships, structures and functions, and our incomplete knowledge on the spatial and temporal variabilities inherent in these ecosystems prevents more detailed analyses and predictions. While this collation has provided a baseline for future work, and has suggested many interesting avenues of enquiry, a vastly greater research effort is required to refine our understanding of the impacts of climate change on the phenologies of southern hemisphere species.</p></sec></sec><sec sec-type="supplementary-material" id="s5"><title>Supporting Information</title><supplementary-material content-type="local-data" id="pone.0075514.s001"><label>Appendix S1</label><caption><p><bold>Long-term phenological data sets (>10 years in length) ending before 1990.</bold> These were not used in the present study but could provide useful baseline data for future studies.</p><p>(PDF)</p></caption><media xlink:href="pone.0075514.s001.pdf"><caption><p>Click here for additional data file.</p></caption></media></supplementary-material><supplementary-material content-type="local-data" id="pone.0075514.s002"><label>Appendix S2</label><caption><p><bold>WinBUGS code used to estimate mean trends in phenology across plants and birds together with a plot of the posterior distribution for means and 95% credible intervals.</bold> We used non-informative priors N(0, 10<sup>6</sup>) for the means and U(0, 100) for the standard errors, and ran three chains of length 1.2 million of which the first 200000 samples were discarded as burn-in and inference was drawn from the rest of the chains after thinning by a factor of 20.
