In the present study the diel and seasonal variations of the total fish abundance (number and weight), community parameters (species diversity, richness, and evenness), multivariate changes in species composition of the fish community, and the influence that exert on them the environmental conditions, were analyzed in the Pueblo Viejo Lagoon,...
A través de seis ciclos bimestrales de 24-h, se analizaron los patrones nictímeros y estacionales en la abundancia total (número y peso) y los cambios en la composición de especies (incluyendo riqueza, diversidad, equidad y dominancia de especies) de la comunidad de peces en la laguna de Pueblo Viejo, Veracruz,...
The La Mancha coastal lagoon is a mixohaline-eutrophic system according to its annual average of salinity and chlorophyll concentration, with a strong influence of the opening-closing dynamics of the bar, which affects its hydrological, biological and ecological cycles. We identified 57 zooplankton taxa, 45 at the species level and 19...
Se estudió la riqueza de especies y la abundancia relativa de los Dinoflagelados del orden Peridiniales de la bahía de Acapulco, Gro., durante el ciclo anual de febrero de 2010 a febrero de 2011, con el objetivo de conocer las especies más abundantes y frecuentes en la zona; así como...
In this work, seasonal and diel variation of abundance and size structure of the species of mojarras (Teleostei: Gerreidae) were analyzed; as well as environmental factors influencing their variation. 19 diel cycles were made (one for month); a total of 12,500 individuals were collected that corresponding to four genera and...
Spatially, only dissolved oxygen showed significant differences between two kinds of environments, being greater in the submerged vegetation habitat. Similarly, on diel scale the environmental variables tended to show no significant differences among hours. By contrast, seasonally all environmental variables showed significant differences among months, in both type of habitats....
The high diversity of coral reef fishes makes complex the problem of its evaluation at ecosystem level. One of the strategies that allow knowing these communities to a scale of smaller complexity is to detect to the typical species whose ecological parameters (i. e. density, appearance frequency, distribution) they prevail...
Abundance, size structure, reproduction and feeding patterns of Anchoa mitchilli were analyzed in the Pueblo Viejo lagoon, Veracruz, through 12 two-monthly 24-h cycles, in two habitats (with and without submerged vegetation). Abundance did not show differences between habitats, but seasonal significant peaks of abundance occurred during January and March. Moreover,...
Durante el año 2001 se realizaron seis campañas de trabajo hacia el área de arrecifes del Caribe Mexicano en el estado de Quintana Roo, en este estado se encuentra a su vez el corredor Turístico Cancún-Tulúm en donde se encuentra circunscrito el sistema arrecifal Akumal, el área de estudio es...
