Abstract
Abstract: The largest damming project to date, the Three Gorges Dam has been built along the Yangtze River (China), the most species‐rich river in the Palearctic region. Among 162 species of fish inhabiting the main channel of the upper Yangtze, 44 are endemic and are therefore under serious threat of global extinction from the dam. Accordingly, it is urgently necessary to develop strategies to minimize the impacts of the drastic environmental changes associated with the dam. We sought to identify potential reserves for the endemic species among the 17 tributaries in the upper Yangtze, based on presence/absence data for the 44 endemic species. Potential reserves for the endemic species were identified by characterizing the distribution patterns of endemic species with an adaptive learning algorithm called a “self‐organizing map” (SOM). Using this method, we also predicted occurrence probabilities of species in potential reserves based on the distribution patterns of communities. Considering both SOM model results and actual knowledge of the biology of the considered species, our results suggested that 24 species may survive in the tributaries, 14 have an uncertain future, and 6 have a high probability of becoming extinct after dam filling.

Among 162 species of fish inhabiting the main channel of the upper Yangtze, 44 are endemic and are therefore under serious threat of global extinction from the dam. Accordingly, it is urgently necessary to develop strategies to minimize the impacts of the drastic environmental changes associated with the dam. We sought to identify potential reserves for the endemic species among the 17 tributaries in the upper Yangtze, based on presence/absence data for the 44 endemic species. Potential reserves for the endemic species were identified by characterizing the distribution patterns of endemic species with an adaptive learning algorithm called a “self‐organizing map” (SOM). Using this method, we also predicted occurrence probabilities of species in potential reserves based on the distribution patterns of communities. Considering both SOM model results and actual knowledge of the biology of the considered species, our results suggested that 24 species may survive in the tributaries, 14 have an uncertain future, and 6 have a high probability of becoming extinct after dam filling.</abstract><abstract lang="es">Resumen: El proyecto de represa más grande a la fecha, la Presa Three Gorges fue construida en el Río Yangtze (China), el río con mayor riqueza de especies en la región Paleártica. Entre las 162 especies de peces que habitan el canal principal del alto Yangtze, 44 son endémicas y por tanto están seriamente amenazadas de extinción global por la presa. Consecuentemente, es urgente desarrollar estrategias para minimizar los impactos de los cambios ambientales drásticos asociados con la presa. Tratamos de identificar las reservas potenciales para las especies endémicas entre los 17 afluentes en el alto Yangtze, en base a datos de presencia y ausencia de las 44 especies endémicas. Se identificaron las reservas potenciales para la especies endémicas caracterizando los patrones de distribución de especies endémicas con un algoritmo de aprendizaje adaptivo denominado “mapa auto‐organizante” (MAO). Con este método, también predijimos las probabilidades de ocurrencia de especies en reservas potenciales en base a los patrones de distribución de las comunidades. Tomando en cuenta tanto los resultados del modelo MAO como el conocimiento actual de la biología de especies en consideración, nuestros resultados sugieren que 24 especies pueden sobrevivir en los afluentes, 14 tienen un futuro incierto y 6 tienen una alta probabilidad de extinguirse después del llenado de la presa.</abstract><subject lang="en"><genre>keywords</genre><topic>community patterning</topic><topic>endemic species</topic><topic>fish</topic><topic>reserve design</topic><topic>Three Gorges Dam</topic></subject><subject lang="en"><genre>keywords</genre><topic>diseño de reserva</topic><topic>especies endémicas</topic><topic>modelo de comunidad</topic><topic>peces</topic><topic>presa Three Gorges</topic></subject><relatedItem type="host"><titleInfo><title>Conservation Biology</title></titleInfo><genre type="journal">journal</genre><identifier type="ISSN">0888-8892</identifier><identifier type="eISSN">1523-1739</identifier><identifier type="DOI">10.1111/(ISSN)1523-1739</identifier><identifier type="PublisherID">COBI</identifier><part><date>2003</date><detail type="volume"><caption>vol.</caption><number>17</number></detail><detail type="issue"><caption>no.</caption><number>6</number></detail><extent unit="pages"><start>1748</start><end>1758</end><total>11</total></extent></part></relatedItem><identifier type="istex">DCD1D7F138FE9E50EDD32D68EA6F3A52F8470D1B</identifier><identifier type="DOI">10.1111/j.1523-1739.2003.00430.x</identifier><identifier type="ArticleID">COBI430</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Science Inc</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
