California sea lion (CSL, Zalophus californianus) abundance has declined in different localities across this species’ Mexican distribution. However, Los Islotes rookery the southwestern Gulf of (GoC) deviates from pattern. It is vital to gather ecological knowledge CSL settlement and its surroundings better understand population GoC. This study aimed determine foraging habits sex age classes. Sixty-five samples were collected for stable isotope analysis (δ13C δ15N). The data analyzed using a...
Female northern elephant seals (Mirounga angustirostris) are migratory animals that form colonies along the coasts of California and Baja Peninsula, Mexico. A recent decline in abundance has been recorded this species Mexican distribution, which is an important reason to investigate different ecological processes operating these colonies. The aim study was determine values stable isotope ratios (δ13C δ15N) pup fur as foraging maternal indicators. During same breeding season (2015), samples...
The Parque Nacional Sistema Arrecifal Veracruzano (hereafter called PNSAV) is the largest coral reef extension in central region of Gulf Mexico. These reefs are unique since they have developed near a coastal environment that directly influenced by discharges Veracruz city, rivers located on continental shelf, and port Veracruz. This study evaluates functional diversity, terms richness, evenness, divergence, PNSAV fish community. We were interested quantifying any similarities or differences...
The competitive exclusion principle establishes that the coexistence of closely related species requires a certain degree resource partitioning. However, populations have individuals with different morphological or behavioral traits (e.g., maturity stages, sexes, temporal spatial segregation). This interaction often results in multi-level differentiation food preferences and habits. We explored such partitioning between within three batoid species: Hypanus dipterurus, Narcine entemedor,...
Hotspots are priority marine or terrestrial areas with high biodiversity where delineation is essential for conservation, but equally important their linkage to the environmental policies of overall region. In this study, fish diversity presences were linked abiotic conditions and different habitat types reveal multi-species hotspots models predicted by ecological niche modelling methods within Bay La Paz, Mexico (south Gulf California). The abiotically suitable 217 species identified based...
Abstract Coexistence among sympatric species requires a certain degree of resource partitioning. In the Mexican South Pacific, information regarding coexistence Stenella attenuata ( SA ) and longirostris SL is lacking. Stable isotope analyses (δ 15 N δ 13 C) were conducted to assess differences in feeding habits infer trophic position amplitude as well habitat use, based on Bayesian inference random forest (RF) classifier. Potential relationships with other assessed by mixing models. Feeding...
