Introduction
I have broad interests in shorebird ecology and conservation in productive systems. I am currently working on a research project to integrating shorebird-friendly best management practices at shrimp farms in coastal wetlands within the Pacific Flyway.

Article
Full-text available
Varying environmental conditions and energetic demands can affect habitat use by predators and their prey. Anthropogenic habitats provide an opportunity to document both predation events and foraging activity by prey and therefore enable an empirical evaluation of how prey cope with trade-offs between starvation and predation risk in environments o...

Article
How to improve habitat quality for wildlife is of particular importance in areas dedicated to food production, due to increasing pressures of global demands associated to human population growth. Semi-intensive aquaculture ponds can provide a potentially important foraging habitat for migratory shorebirds throughout the non-breeding season. Therefo...
Article
Full-text available
Loss of wetlands may restrict foraging opportunities for many species of migratory shorebirds that depend on wetlands during the non-breeding periods. In addition, tidal cycles, both daily (high and low tides) and lunar (spring and neap tides), periodically modulate the availability of foraging areas within coastal wetlands, which can limit area an...
Article
Wetland loss has driven negative effects on biodiversity by a reduction in potential available habitats, directly impacting wetland-dependent species such as migratory shorebirds. At coastal areas where tidal cycles can restrict food access, the degree to which density of foraging birds is mediated by conspecific abundance or by the available areas...
Article
Full-text available
Shrimp aquaculture farms have greatly expanded at tropical areas worldwide, especially during the past three decades. One of the main core areas of this expansion was the northwestern coast of Mexico, prompting conservation concern for the shorebird populations that spend the nonbreeding period (October to March) in the region. We conducted a serie...
Article
Full-text available
Background: It was suggested that ecological patterns can be used to infer the nature of ecological processes (i.e., competition) that structure communities. Analysis of patterns of resource partitioning under the classical niche paradigm (competitive niche differentiation in exploiting limited resources) has traditionally been used to understand t...

Resumen Estudiamos la abundancia y distribución estacional de las aves acuáticas en la laguna de Acuitlapilco, Tlaxcala, México. De febrero de 2011 a enero de 2012, realizamos censos en puntos de conteo para el registro de las especies. Registramos un total de 36 especies de aves acuáticas con una abundancia total acumulada de 48,794 individuos. Do...

We report noteworthy bird records of Anous stolidus, Stellula calliope, Sphyrapicus varius, Myiopagis viridicata, Dendroica pensylvanica and Pheucticus ludovicianus from central Sinaloa, most of them obtained during mist net surveys. At first sight the records seem to be vagrants, but the severe habitat modification of Sinaloa's coastal zone could...
