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 ...

Extreme Rainfall Contribution and Isotopic Excursion of Tropical Storm Alberto in Northeastern Mexico. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Tropical cyclones are critical extreme rainfall events that can temporarily mitigate drought impacts in semiarid regions. Despite the well‐known North Atlantic hurricane season, the propagation of isotopically distinct rainfall pulses across semiarid landscapes of Mesoamerica is largely unknown.

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 ...

Water Parameters and Hydrodynamics in Rivers and Caves Hosting Astyanax mexicanus Populations Reveal Macro-, Meso- and Microhabitat Characteristics. [PDF]

Ecol Evol
From 2009 to 2025, we have recorded the physicochemical parameters of the water and the hydrological regimes at localities hosting Astyanax mexicanus cavefish and surface fish populations in Mexico. Sampling 13 caves and 30 surface stations revealed strong signatures of the two macrohabitats, but also significant differences in specific water ...

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator-prey conflict within the carnivorous Pinguicula subgenus Temnoceras. [PDF]

Am J Bot
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

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.

A new treefrog of the genus Charadrahyla (Anura, Hylidae) from Oaxaca, Mexico, with comments on the conservation status and distribution of related species [PDF]

Herpetozoa
We describe a new species of Charadrahyla from the Sierra Juárez portion of the Sierra Madre Oriental in the state of Oaxaca, Mexico, and provide morphological and molecular data to support the novelty of this species.

Connectivity among jaguar populations in the Sierra Madre Oriental, México [PDF]

Therya, 2015
Introduction: The jaguar (Panthera onca) is an apex carnivore that is vulnerable to habitat fragmentation, and some of its populations are believed to be isolated in Mexico where it is classed as endangered. The main the objective of our study was to evaluate connectivity of available jaguar habitat from the Sierra Madre Oriental of Mexico (SMO ...

Dominios climáticos de la Sierra Madre Oriental y su relación con la diversidad florística

Revista Mexicana de Biodiversidad, 2017
La Sierra Madre Oriental ha perdido hasta el 30% de su vegetación, lo que hace imperativo conocer mejor su biodiversidad, así como las variables ambientales que explican su distribución.

Exploraciones en la Sierra de Juárez

Botan‪ical Sciences, 1951
Comúnmente refiere a dicha sierra como la de Juárez pero, en realidad, geográficamente se trata de la Sierra Madre oriental. Esta región apartada y de dificil acceso, se divide en varias partes.
