“…These organisms can be found in both estuaries and coastal lagoons; generally, juveniles occur in estuaries and adults in the coastal zones (Abarca et al 2004, Abarca et al 2007 The morphologic characteristic that distinguish the members of this family is the extremely protusible jaws. A member of this family is Diapterus auratus, the Irish Pompano or Mojarra Guacha.…”

Sagittae otoliths are the most studied because of their morphological variability and size; the sagittae may also have valuable taxonomic use and for D. auratus has not yet been described. In the present study we present a morphological description of the sagitta otolith and an analysis of its correlation with various morphometric parameters. The biological material was captured with a beach seine in the coasts of Alvarado and Port of Veracruz, from November 2009 to June 2010. Sagittae were extracted, cleaned, photographed (SEM and optical), and measured. The analysis included the correlations between sagitta's length and width, versus the fish standard length, height and weight, for a total of 449 fishes. The comparison between left and right sagitta showed no significant difference in both otolith length and width (t-tests, p<0.05) for each sex. The right otolith was used for the correlations for both males and females and the Fisher test (d.f. 161 and 143, p<0.001) showed no significant differences in the slopes and intersections between them. The otolith length vs. fish weight correlation showed a positive allometric growth in males (b=3.9754, p<0.05) and females (b=4.3168, p<0.05). Rev. Biol. Trop. 61 (1): 139-147. Epub 2013 March 01.

“…consumption of nonliving organic matter) as a trophic interaction has been argued (Jord an et al 2006; Jord an & Osv ath 2009), since it consists of a node that only passively receives matter from all other trophic levels. However, detritus has been shown to have a strong effect on the network structure in both aquatic and terrestrial ecosystems (Hagen et al 2012) and is a central component of food webs (Abarca-Arenas et al 2007). We therefore suggest that neglecting detritus could severely hamper our abilities to utilize network analyses to enhance our understanding of ecological relationships.…”

Summary1. Network analysis, a branch of discrete mathematics that quantifies the structure of links between a set of nodes, is emerging as a powerful methodology to approach complex ecological interactions. 2. There has been a rapidly increasing body of research targeting the topological description of trophic interactions. Here we categorize studies applying a topological approach to empirical trophic networks, with the aim of identifying recent trends and deficiencies in this approach to analyse trophic interactions.3. There were biases in the taxonomic groups addressed and in the methodological approaches used for data collection and analyses. Studies on antagonistic interactions were generally focused on a single kind of bipartite interaction, and most studies compared network attributes across time, ecosystems or treatments. 4. We encourage a broader use of both interlinked and unipartite networks that would allow for describing indirect effects of trophic interactions, as well as time series of networks across seasons and phenological states of organisms. We also noted shortages of studies identifying interaction structures across levels of organization, on the correspondence between network structure and function, and particularly of studies on the behaviour of trophic networks in the face of environmental perturbations, which could provide guidance for preserving ecological interactions.

“…The trophic dynamic concept in ecology was established by Lindeman (1942). Food web dynamics showed a variable structure among the different seasons of the year (Abarca-Arenas et al 2007). Trophodynamic aspects of fish in Yucatan have been studied, for example, by Vega-Cendejas et al (1987).…”

“…Most ecological research has relied on trophic groups as a classification scheme for defining functional diversity (Micheli and Halpern, 2005). Food web analysis has also been a well-documented tool to achieve a fisheries ecosystem approach and to understand the ecosystem under various scenarios (Abarca-Arenas et al, 2007;Pauly et al, 1998Pauly et al, , 2000. Both abiotic (temperature, salinity, substrate) and biotic factors (competition, predation) play a role in shaping macrobenthic communities (Angermeier and Winston, 1998).…”

Classical approaches to trophic ecology of marine species has focused on trophic structure, trophodynamics, dominant and keystone species, ecosystem maturity, energy transfer, and anthropic effects. A recent breakthrough for evaluating the structure of communities has been the application of phylogenetic methods to community ecology. This recent approach is known as community phylogenetics. Although this perspective is still not common in trophic studies, phylogenetic methods promise new insights into the old ecological question on how communities are assembled in time. Integrating phylogenetics and ecosystem function creates the possibility of predicting ecological consequences of biodiversity shifts in a changing world. Once we understand the structure and functioning of the ecosystem in a historical context, we should be able to avoid human or natural disturbances that draw a system away from its state of maximum complexity.
