Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Shark breeding grounds and seasons in the Gulf of California: Fishery management and conservation strategy

Ciencias Marinas, 2009
Sharks show high biological fragility and, given the intense fishing regimes to which they are exposed in the Gulf of California, it is necessary to establish a conservation and management strategy providing for the protection of their nursery areas. We

California's vernal‐pool mousetails (Myosurus, Ranunculaceae): Phylogenetic analysis of ddRADseq data, hybridization tests, and species delimitation

Journal of Systematics and Evolution, EarlyView.
We present the first phylogenetic analysis of the Californian species of Myosurus. Our ddRADseq analysis reveals considerably more diversity than what was recognized in recent floristic treatments. Myosurus minimus subsp. apus was found to be a rare species restricted to Southern California and northwestern Baja California.

Subsistence hunting shapes the spatial variation of jaguar densities in community‐managed forests

Journal of Zoology, EarlyView.
Jaguars and people can coexist in community‐managed forests, but distance matters. In Guatemala's Maya Biosphere Reserve, jaguar numbers increased markedly in areas harder to reach on foot, yet jaguars were still found near communities, showing that responsibly managed forests can support jaguar populations while allowing people to maintain traditional

“They Look At Us Like Parasites”: The Corporeal Stigmatization and Pathologization of Deportees in Tijuana, Mexico

Medical Anthropology Quarterly, EarlyView.
Abstract This article examines the embodied and institutional forms of marginalization experienced by Mexican deportees in Tijuana. Drawing on ethnographic fieldwork conducted in clinics and social service organizations, it explores how deportees are corporeally stigmatized, denied legal recognition, and pathologized as addicts in need of coercive ...

In situ ruminal digestibility and degradability of Macrocystis pyrifera and Sargassum spp. In bovine livestock

Ciencias Marinas, 1998
An alternative for the use of macroalgae as forage was explored since the technology for its processing is simple and accessible. In this study we determined the chemical composition, energy contribution, in situ degradability and ruminal digestibility ...

“They need to get a new program”: Experiential frictions with the gender of care in the 12 step program for ethnically Mexican women

Medical Anthropology Quarterly, EarlyView.
Abstract Using gender as an analytic, I parse out how the historical gendered, classed, and racialized roots of the 12 Step Program remain present in its therapeutic model, even in global contexts beyond its original formulation. These foundations continue to shape therapeutic logics and experience within the Program, in positive and negative ways.

Host Identity Shapes Taxonomic Composition and Predicted Functional Potential of Coral-Associated Bacteriomes in the Gulf of California

Microbiology Research
Coral-associated microbial communities play a critical role in the health and resilience of reef ecosystems; however, the relative importance of host identity and environmental factors in shaping these communities remains unclear, particularly in ...
