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,...
Se analizó el sistema urogenital de 76 especies de peces, correpondiendo una a los Agnatha, seis a los Elasmobranchii y 69 a los Teleostei. Se describe el patrón morfológico de cada una de las clases de peces, seleccionando a la lamprea de Chapala Lampetra spadicea, a la raya mariposa Gymnura...
El sistema Pom-Atasta asociado a la Laguna de Términos, se encuentra dentro del polígono decretado como Área de Protección de Flora y Fauna (1994) y Sitio Ramsar (2004). Tiene importancia científica, social y económica, ya que es utilizado para realizar parte de los ciclos de vida de una gran diversidad...
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...
Coastal lagoons are systems with high levels of productivity and a big biological diversity as a result of a high ecological complexity, due to the different environmental processes that result from seasonal, diel and tides cycles periods and to the abrupt changes of the environmental variables of these periods. The...
A great majority of studies mark the importance of coastal systems, mainly in estuaries due to its high biological, physical and chemical variability as a result of variations in environmental parameters to seasonal level, with greater emphasis on diel level, allowing a closer the behavior of the composition in such...
