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

open access: yesAmerican Journal of Botany, Volume 112, Issue 11, November 2025.
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]

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 1, January 2026.
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]

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
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]

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
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]

open access: yesAmerican Journal of Botany, Volume 113, Issue 2, February 2026.
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 (Panthera onca, Linnaeus 1758) (Mammalia, Felidae) in Northwestern Mexico, With a Record of Collaborative Interactions [PDF]

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
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.
