Algas marinas bentónicas de Mazatlán, Sinaloa, México

Abstract

Se llevaron a cabo 4 muestreos de algas marinas bentónicas en 3 localidades de las costas de Mazatlán, Sinaloa, mediante los cuales se determinó la presencia de 124 especies de algas marinas. Se identificaron 7 especies de Cyanophyceae, 72 de Rho­dophyceae, 12 de Phaeophyceae, 7 de Baci-llariophyceae y 26 de Chlorophyceae. Cada especie se acompaña de datos sobre su distribución en el área de estudio, el estado reproductivo, el nivel de marea, el modo, las facies y el epifitismo. Se comparó la diversidad de las especies entre la estación climática de lluvias y la de secas, durante 1971, 1983, 1987 y 1988. Rhodophyceae dominó en términos de diversidad en relación con las 4 clases restantes. La ficoflora de Mazatlán es tropical y es más diversa en la estación de lluvias.

Comparison of ecological diversity and species composition of macroalgae, benthic macroinvertebrates, and fish assemblages between two tropical rocky reefs

“…Thus, macroalgae, molluscs and fishes were more diverse in summer, and crustaceans and echinoderms in winter. A similar trend, that is higher diversity during warmer periods, had been reported for algae and fishes for the region (Mateo-Cid & Mendoza-González 1991, 1992Mendoza-González et al 1994, Aburto-Oropeza & Balart 2001, Alvarez-Filip et al 2007, Galvan-Villa et al 2011, López-Pérez et al 2012. Reyes-Bonilla and Alvarez-Filip (2008) found the same pattern in reef fishes based on taxonomic distinctness.…”

A taxonomic account of species in the tribe Spongoclonieae (Ceramiaceae, Ceramiales, Rhodophyta) reported from Atlantic and Pacific Mexico

“…Although our SW Gulf of California and Pacific Mexico specimens are mostly in agreement with descriptions of Dawson (1962a) and Bucher and Norris (2014), they are taller and the cells of the main axes are larger. (Mendoza-González et al, 1994;Mateo-Cid et al, 2006;Bucher and Norris, 2014;Norris et al 2017;herein). WESTERN ATLANTIC: Brazil (Oliveira Filho, 1977).…”

“…In the laboratory, macroalgae were washed free of organic and inorganic debris, rinsed with tap water and dried to constant weight in a convection oven at 60 °C (close to 3 d), after taxonomic determination using algal morphological characteristics (Dawson, 1956(Dawson, , 1961Mendoza-González et al, 1994). Weight was determined in a digital balance (±0.05 g).…”
