Temporal and spatial variations in the structure of the rocky reef fish community of the southwest Gulf of California, Mexico

In the present work, these communities are evaluated through visual censuses at four sites of the southwestem coast of the gulf. The specifíc richness, frequency, evenness and...

In the present work, these communities are evaluated through visual censuses at four sites of the southwestem coast of the gulf. The specifíc richness, frequency, evenness and diversity were analyzed at each site. Seasonal changes and differences among the sites studied were also analyzed. A total of 76 species was registered. Five species were the most abundant in most of the zones and during the greater part of the study: Stegastes spp., Thalassoma lucasanum, Abudefduf troschelii, Chromis atrilobata and Haemulon maculicauda. Only the first three species were present in all censuses made. Differences were found in the structure of the communities between different seasons and between study sites; however, the diversity values had no significant differences. The zone with the greatest number of species was Cueva de León. A positive relationship was found between specific richness and temperature. En el Golfo de California existe una gran cantidad de arrecifes rocosos; sin embargo, son pocos los estudios sobre las comunidades de peces que los habitan. En el presente trabajo se evalúan estas comunidades mediante censos visuales en cuatro sitios de la costa suroeste del golfo. Se analizaron la riqueza específica, frecuencia de ocurrencia, equitatividad y diversidad en cada sitio, así como los cambios que se presentaron entre las estaciones del año y entre los sitios estudiados. Se registró un total de 76 especies; las cinco más abundantes fueron Stegastes spp., Thalassoma lucasanum, Abudefduf troschelii, Chromis atrilobata y Haemulon maculicauda, las cuales presentaron abundancias importantes en la mayoría de las zonas y durante la mayor parte del tiempo del estudio. Sólo las tres primeras especies estuvieron presentes en todos los censos realizados. La estructura de las comunidades presentó diferencias entre las estaciones y entre los sitios de estudio; sin embargo, el valor de diversidad no varió significativamente. La zona con un mayor número de especies fue Cueva de León. Se detectó una relación positiva entre la riqueza específica y la temperatura.
