Abstract
1. We report patterns of temporal variation in the recruitment of roach (Rutilus rutilus). The data consist of the annual abundance of the first 2 year‐classes, 0+ and 1+ fish, at four sites in the Rhône River (France) between 1987 and 1997. Over this 11‐year period both 0+ and 1+ fish fluctuated strongly.
2. Cross‐correlation indicated high spatial synchrony in 0+ dynamics, although correlations among sites in 1+ dynamics were weaker. No clear pattern was apparent in the relationship between the level of synchrony and distance between pairs of sites.
3. The spatial synchrony in 0+ fish could be attributable to large‐scale variations in weather, influencing water temperature. Total body length of 0+ roach was correlated with water temperature (expressed in degree‐days over 12 °C), and water temperature was the main factor explaining inter‐annual variation in 0+ cohort size. Monthly variation in abiotic factors (measured by standard deviation in water temperature and discharge) did not influence 0+ fluctuations. Correlations with June water temperature suggest that year‐class strength was mainly determined by abiotic factors during the first few months of life.
4. The absence of spatial synchrony in 1+ fluctuations suggests little correlation between survival and abiotic conditions during the first year of life, other factors influencing survival.
5. Survival in the first year was density‐dependent. Intraspecific competition within the 0+ cohort could thus influence the fluctuations in recruitment to older age‐classes.
6. The implications of age‐ or stage‐dependent synchrony in temporal variation for species with complex life histories are discussed. Studying spatial synchrony for the different life history stages could enhance our understanding of the population dynamics of spatially structured species.

We report patterns of temporal variation in the recruitment of roach (<i>Rutilus rutilus</i>). The data consist of the annual abundance of the first 2 year‐classes, 0+ and 1+ fish, at four sites in the Rhône River (France) between 1987 and 1997. Over this 11‐year period both 0+ and 1+ fish fluctuated strongly.
2. Cross‐correlation indicated high spatial synchrony in 0+ dynamics, although correlations among sites in 1+ dynamics were weaker. No clear pattern was apparent in the relationship between the level of synchrony and distance between pairs of sites.
3. The spatial synchrony in 0+ fish could be attributable to large‐scale variations in weather, influencing water temperature. Total body length of 0+ roach was correlated with water temperature (expressed in degree‐days over 12 °C), and water temperature was the main factor explaining inter‐annual variation in 0+ cohort size. Monthly variation in abiotic factors (measured by standard deviation in water temperature and discharge) did not influence 0+ fluctuations. Correlations with June water temperature suggest that year‐class strength was mainly determined by abiotic factors during the first few months of life.
4. The absence of spatial synchrony in 1+ fluctuations suggests little correlation between survival and abiotic conditions during the first year of life, other factors influencing survival.
5. Survival in the first year was density‐dependent. Intraspecific competition within the 0+ cohort could thus influence the fluctuations in recruitment to older age‐classes.
6. The implications of age‐ or stage‐dependent synchrony in temporal variation for species with complex life histories are discussed. Studying spatial synchrony for the different life history stages could enhance our understanding of the population dynamics of spatially structured species.</p></abstract></abstractGroup></contentMeta></header></component></istex:document></istex:metadataXml><mods version="3.6"><titleInfo lang="en"><title>Large‐scale synchrony and inter‐annual variability in roach recruitment in the Rhône River: the relative role of climatic factors and density‐dependent processes</title></titleInfo><titleInfo type="abbreviated" lang="en"><title>Large‐scale synchrony in river fish dynamics</title></titleInfo><titleInfo type="alternative" contentType="CDATA" lang="en"><title>Large‐scale synchrony and inter‐annual variability in roach recruitment in the Rhône River: the relative role of climatic factors and density‐dependent processes</title></titleInfo><name type="personal"><namePart type="given">G.</namePart><namePart type="family">Grenouillet</namePart><affiliation>Laboratoire d’écologie des Hydrosystèmes Fluviaux, Université Lyon I, 43 Boulevard du 11 novembre 1918, 69622 Villeurbanne cedex, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">B.</namePart><namePart type="family">Hugueny</namePart><affiliation>Antenne IRD, Laboratoire d’écologie des Hydrosystèmes Fluviaux, Université Lyon I, 43 Boulevard du 11 novembre 1918, 69622 Villeurbanne cedex, France</affiliation><role><roleTerm type="text">author</roleTerm></role></name><name type="personal"><namePart type="given">G.
