Dissimilar climatic niche is predictive of contrasting historical demographic changes and altitudinal shifts in related oak species (Quercus). [PDF]

Am J Bot
Abstract Premise Comparative surveys allow us to characterize the influence of specific factors on population genetic diversity and structure. We conducted a comparative phylogeographic study for three Mexican oak species to identify how their climatic niche preferences and breadth may have influenced historical demography and range shifts during ...

Pleistocene Climate Changes and Lineage Diversification of <i>Sphenarium</i> Grasshoppers (Orthoptera: Pyrgomorphidae). [PDF]

Ecol Evol
We investigate the phylogeographic history and paleodistribution patterns of four closely related grasshopper species of the genus Sphenarium to test the relative impact of Pleistocene climate fluctuations on their diversification. We found that each species responded differently to these fluctuations, but their divergence, distribution, and ...

Jaguar Density at the Northeastern Limit of Its Distribution in Mexico. [PDF]

Ecol Evol
This study presents the first estimate of jaguar density in northeastern Mexico using a spatial capture–recapture model with random thinning, which incorporates both identified and unidentified camera trap detections. Conducted over 91 days with 104 cameras, the model yielded a density of 1.29 individuals per 100 km2 in the El Cielo–Sierra de Tamalave ...

High Elevation Occurrences of Jaguars (<i>Panthera onca</i>, Linnaeus 1758) (Mammalia, Felidae) in Northwestern Mexico, With a Record of Collaborative Interactions. [PDF]

Ecol Evol
Jaguars in the northern end of their distribution have recently become the center of conservation efforts; however, the State of Chihuahua has been underrepresented in monitoring projects. We present five new records of jaguars in high altitudes as well as the first evidence of two jaguars exhibiting cooperative behavior in Mexico.

Leishmaniasis Transmission Risk at the Forest-Peridomestic Interface in an Area of Southern Sinaloa, Mexico: Entomological, Molecular, and Climatic Evidence. [PDF]

J Parasitol Res
Leishmaniasis, caused by Leishmania spp. and transmitted by phlebotomine sand flies, affects almost 1,000,000 people annually across more than 90 countries. In Mexico, growing evidence of locally acquired transmission in northwestern states makes ecoepidemiological work increasingly urgent.
