The species-area relation has been a recurrent theme in ecology and other sciences. Here, we present the relationship between the fin-fish species richness and the area of 15 sites along the coast of Veracruz, in the Gulf of Mexico. The sites are estuaries, coastal lagoons, coral reefs and the coastal shelf. Furthermore, using the FishBase data of...

A series of crater lakes exist in the central region of Puebla, Mexico; each one with an endemic species of silverside fishes, with no information about their ecology. Poblana letholepis is an endemic species to the Crater Lake La Preciosa and under human and physical pressure endangering its presence. The weight–length relationship of both sexes a...
Article
Cetaceans are highly mobile species with complex social structures, aspects that play an important role in their fitness such as survival and offspring pro- duction. Population dispersal influences the dynam- ics of social species, which may vary with age, sex, or individual status, thus resulting in segregation; however, sex-related dispersal and...
Article
Studying interactions between cetaceans and humans is fundamental to assess their ecological significance and the impact of human activities on marine wildlife. Delphinids have historically been associated with human maritime activities, and while evidence suggests that such interactions are becoming more frequent worldwide, these remain poorly stu...

Full-text available
Development of ecosystem-based fisheries management models depends, to a large extent, on the availability of trophic interaction data. These models could address ecological questions, examine ecosystem trophic structure, and be used in placement analysis for marine protected areas, among other uses. Many studies on fish trophic interactions have b...

Relationships between some species and their environment may differ by age, sex, hierarchy or individual status within populations; however, despite the changes in coastal environments caused by anthropogenic factors, these are commonly ignored. A two-year study (2006-8) with 41 standard line-transect and photo-Id surveys was designed to determine...

Delphinids have historically been associated with human maritime activities. While evidence suggests that such interactions are increasing worldwide, these remain poorly studied. We assessed the differences in dolphin affinity to interact with fishing operations off the productive Alvarado lagoon, in the western Gulf of Mexico. From May 2006 to Apr...

Continental shelf macrofauna are impacted by trawling and associated by-catch activities. These activities have been predicted to change the macrofaunal community structure and the resulting food web. Four food webs (three seasonal and one pooled) were constructed using shrimp by-catch samples from 21 surveys from 1991 to 1994. Network sociometric...

There is a consensus that fisheries around the world have reached their maximum levels of capture, and, in many cases, overexploitation is apparent. On the basis of FAO data, it has been found that overexploitation can be detected as a decrease in the trophic levels of the fisheries due to the greater energetic cost that maintaining high trophic le...

Composition, spatial distribution, dominance, ecological diversity and evenness of crustacean macrofoulers were analyzed in the Veracruz coral reef system, southwestern Gulf of Mexico. Three test sites were established during May-June 2006 based on their distance from the shoreline and the influence of sewage discharged into the coral reef system....
Article
In the tropho-dynamic analysis of ecosystems the heuristic, discrete concept of trophic level has been replaced by the more realistic, continuous definition of trophic position. In ecological network analysis (ENA) the suite of matrix manipulations called canonical trophic aggregation (CTA) apportions each species’ feeding activity to a series of d...

In their search for ever better trophic models, ecologists have often tried aggregating the number of species in order to better focus upon the variables that most interest them. Previous attempts at aggregating food webs have yielded varied results. We studied a series of different taxonomic aggregations on the same trophic network model of the Ch...
Article
The mechanistic view of ecosystem dynamics, being inherently reversible, seems ill-suited to describe directional behavior, such as ecosystem succession. A more conservative approach, such as one that involves probabilities, seems warranted. Work involving conditional probabilities has led to the development of a systems property called the ascende...
