Introduction
My research interests include: trophic ecology, zooplankton ecology and marine mega-fauna ecology, eco-physiology and behavior. The aim of my research is to understand the behavioral basis of animal feeding ecology, intra-interspecific interactions, movement patterns, and reproduction in short and long term by using different analytical tools (e.g. stable isotope analysis, fatty acids, hormone analysis, satellite tags). All the knowledge acquired during my research will be used to educate and orientate communities and companies that work with marine fauna.

Article
Full-text available
Migration is a complex behavior that has evolved in multiple taxonomic groups as a means of accessing productive foraging grounds and environmentally stable areas suitable for reproduction. For migratory whales that forage throughout the year because of their high energetic demands, changes in the abundance of prey in different areas along their mi...
Article
Full-text available
The biological carbon pump is the process that transports carbon vertically out of the mixed layer in the ocean. Besides the sinking flux of organic particles, active flux due to the daily vertical migration of zooplankton and micronekton promotes a significant carbon transport not fully accounted for or understood in the world’s oceans. The divers...
Article
Although hydrogen isotopes (δ ² H) are commonly used as tracers of animal movement, minimal research has investigated the use of δ ² H as a proxy to quantify resource and habitat use. While carbon and nitrogen are ultimately derived from a single source (food), the proportion of hydrogen in consumer tissues originates from two distinct sources: bod...
Article
Migratory marine megafauna generally move vast distances between productive foraging grounds and environmentally stable breeding grounds, but characterizing how they use these habitats to maintain homeostasis and reproduce is difficult. We used isotope analysis of blue whale skin strata (n = 621) and potential prey (n = 300) to examine their migrat...
Article
Full-text available
World populations or stock distinction of Tursiops truncatus has been difficult to assess, because of large variations in morphology, habitat, feeding habits, and social structure among areas, which may reflect phylogenetic segregation or ecological plasticity. In the Gulf of California, Mexico, two common bottlenose dolphin ecotypes (inshore and o...
Method
Full-text available
This illustrated guide is intended to aid during touristic observation of marine mammals in the Gulf of California. It includes basic information on the proper ways of aproaching the animals, the forbiden practices, some identification characteristics of each species, their main prey, and their conservation status.
Data
GLM analysis relating skin δ15N values to time (Julian date, presented in years). Points represent the actual δ15N values of blue whale skin collected in different zones of the northeast Pacific. Lines represent the fit of the GLM model and the fringe around the lines show the 95% confidence intervals. The gray shaded area represents the meand±SD o...
Data
Information of baleen plates collected from six blue whales. (DOCX)
Data
GLM results relating blue whale skin δ15N values to time (Julian date) in the Gulf of California (GC), California Current System (CCS) and Costa Rica Dome (CRD). (DOCX)
Data
Results from the GAM model sections used to infer δ15N isotopic incorporation rates of blue whale skin strata in Gulf of California (GC) and California Current System (CCS). (DOCX)
Data
Max-t test results comparing the effect of different treatments on skin δ15N, δ13C and weight percent C/N ratios. (DOCX)
Data
Max-t test results for the comparison of δ13C and δ15N values among different skin strata in the Gulf of California (GC) and California Current System (CCS). (DOCX)
Data
GAM analysis relating skin δ13C values to Julian day (presented in months). The points represent the actual δ13C values of skin collected from whales within the Gulf of California (open circles) and the California Current System (open triangles). Lines represent the fit (projections) of the GAM model and the fringe around the lines show the 95% con...
Data
Mean (±SD) δ13C, δ15N, and weight percent C/N ratios of potential blue whale prey from each of the three foraging zones in the northeast Pacific. (DOCX)
Data
Mean (±SD) δ13C, δ15N and weight percent C/N ratios of blue whale baleen plates collected from stranded whales. (DOCX)
Data
Sections used from the GAM model predictions to infer δ15N isotopic incorporation rates of blue whale skin strata in each foraging zone. The lines represent the GAM model fit (predictions) in the Gulf of California (green) and the California Current System (blue). The fringe around the lines show the 95% confidence intervals. The black dot represen...
Data
δ13C values along the baleen plates from six whales, identified as A-F. Points represent actual values, the continuous line (blue: males; red: females) represents the GAM model fit and the fringe around the lines show the narrow 95% confidence intervals. (TIF)
Data
δ13C, δ15N and weight percent C/N ratios of blue whale skin and baleen plates used in this study. (XLSX)
Article
Full-text available
Stable isotope analysis in mysticete skin and baleen plates has been repeatedly used to assess diet and movement patterns. Accurate interpretation of isotope data depends on understanding isotopic incorporation rates for metabolically active tissues and growth rates for metabolically inert tissues. The aim of this research was to estimate isotopic...
