The southwestern Gulf of California has high-value commercial fisheries; however, there are few studies of the taxonomic diversity of fish in this area. Surveys of taxonomic diversity of the fish assemblage at 8 localities near the shore of Bahía de La Paz were undertaken from March 2002 to April 2003. Seasonal changes in diversity of rocky reef fish were analyzed, including taxonomic distance among fish species, using the alpha, alpha average, beta, and gamma diversity indices, the taxonomic distinctness index (TD D*), and the average taxonomic distinctness index (AvTD D+). Submarine visual censuses were carried out along 48 transects measuring 100 × 5 m (500 m2) at 5 m average depth from 09:00-16:00 h. Two seasons were studied: winter with an average temperature of 22.57°C, and summer with an average temperature of 27.09°C. 24,633 fishes, belonging to 92 species and 67 genera were recorded. According to the alpha average, beta, and gamma diversity indices, August had the highest diversity (19.5, 40.5, and 60 species, respectively), and December had the lowest diversity (20.6, 27.4, and 48 species, respectively). Spatial analysis of TD and AvTD were not significantly different, and analysis by season of these indices was not significant different. Greater anthropogenic impact would cause differences in TD and AvTD found at El Guano compared with other locations.
Con profunda emoción y tristeza he recibido la noticia de la pérdida de una gran amiga y colega, compañera de lucha y de trabajo por más de cuatro décadas. El vacío causado por la muerte de Elda quedará para siempre, pero resta la imagen sugestiva de una mujer que ha vivido muy intensamente los altos y bajos que caracterizan toda existencia humana. Llena de temperamento, alegre, risueña y a veces irónica, no tuvo jamás problemas de decir claramente lo que pensaba, tanto de las cosas como de las personas, pero su marcado sentido del humor contribuyó siempre a sofocar eventuales resentimientos personales. El entusiasmo de Elda por el fomento y la realización de nuevas ideas era admirable y contagioso, pero ella nunca perdía el sentido del realismo. Su inteligencia vivaz le permitía individualizar rápidamente los puntos claves de cualquier tema de estudio y, en consecuencia, intervenir efectivamente en su debate.
