Changes in the taxonomic diversity of the reef fish community of San José Island, Gulf of California, Mexico

Latitudinal variation in structure and function of conspicuous reef fish assemblages along the western Gulf of California

“…Considering the spatial and temporal limitation of data, we found that the fish communities of the Gulf of California are dominated by a small number of species (Fig. 2, Table 1), which have also been reported as the most abundant and frequent in other studies: A. troschelii, C. atrilobata, S. rectifraenum, and T. lucasanum, belt transects (Aburto-Oropeza & Balart, 2001;Barjau-González et al, 2012;Pérez-España et al, 1996;Sánchez-Ortiz et al, 1997;Viesca-Lobatón et al, 2008) and stationary censuses (Álvarez-Filip et al, 2006). These are non-specialist, herbivore or omnivore fishes (trophic level from 2.0 to 3.4; Froese & Pauly, 2017) that are so widely distributed that genetic studies have considered them as having a single panmictic population in the Gulf, and connectivity along the eastern Pacific (Bernardi et al, 2014;Guevara-Reyna, 2017;Meléndez & Mayor, 2014).…”

“…Although the fish community structure of reefs in the Gulf of California have been studied since the 1970s (Thomson & Gilligan, 2002), it was not until the 1990s that the majority of the information was produced, first for southern localities (< 25° N, Barjau-González et al, 2012;Pérez-España et al, 1996;Rodríguez-Romero et al, 2005), and then for the north zone (> 25° N, Campos-Dávila et al, 2005;Viesca-Lobatón et al, 2008). In addition, there are several systematic checklists for specific areas of the Gulf (Abitia-Cárdenas et al, 1994;Balart et al, 1995;Del Moral-Flores et al, 2013;Sánchez-Ortiz et al, 1997;Villarreal-Cavazos et al, 2000).…”

Reproductive behaviour and concurrent sound production of Gulf grouper Mycteroperca jordani (Epinephelidae) at a spawning aggregation site

“…Consequently, M. jordani is rarely observed throughout its range (Aburto‐Oropeza et al . ; Barjau‐González et al ., ; Jorgensen et al ., ; Mascareñas‐Osorio et al ., ) and contributes to less than 1% of contemporary landings in the southern Gulf of California (Erauskin‐Extramiana et al ., ; Erisman et al ., ), which are largely comprised of juveniles (Aburto‐Oropeza et al ., ). The species is currently classified as Endangered by the IUCN due to a decreasing population trend and the targeted fishing of vulnerable spawning aggregations (Erisman & Craig, 2018).…”

Recently, these indices were used to evaluate the taxonomic diversity of different marine groups of different regions of Mexican Pacific including stony corals (Reyes-Bonilla et al, 2013), echinoderms (Rios-Jara et al, 2013), bivalves (Esqueda-González et al, 2014) and fishes (Barjau-González et al, 2012; identificar dónde hay vacíos en los inventarios actuales como en cuanto al número de especímenes por taxón, y con respecto a la cobertura geográfica y estacional (Nelson et al, 2013). Además, una evaluación confiable requiere la actualización taxonómica de las especies involucradas para servir como referencia para futuras investigaciones en la misma región y para hacer comparaciones con otras regiones (Serviere-Zaragoza, 1993;Candelaria-Silva, 1996;León, 1996).…”

Recientemente, estos índices se utilizaron para evaluar la diversidad taxonómica de diferentes grupos marinos de diferentes regiones del Pacífico mexicano, incluidos los corales duros (Reyes-Bonilla et al, 2013), equinodermos (Ríos-Jara et al, 2013), bivalvos (Esqueda-González et al, 2014) y peces (Barjau-González et al, 2012;Herrera-Valdivia et al, 2016).
