Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

A Characterisation of Extreme‐Heat Occurrence and Its Trends in Mexico Based on a High Resolution Dataset

open access: yesInternational Journal of Climatology, Volume 46, Issue 3, 15 March 2026.
As Mexico faces rising temperatures and increasing events of extreme heat, improvements in the analysis and characterisation of these phenomena are necessary, as they offer new insights into the spatial variability of such trends and their underlying causes.

Freshwater Conservation Priority Areas Are Threatened by Global Mining Activities

open access: yesGlobal Change Biology, Volume 32, Issue 3, March 2026.
Meeting global mineral demands, including those for decarbonization, risks amplifying threats to freshwater biodiversity. This study presents the first global mapping of conflicts between mining and freshwater conservation, revealing that mining may contaminate up to 1.8 million km of rivers, with over 18% within conservation priority areas.

Ungulate prey availability to inform Mexican wolf recovery within its historical range

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We estimated the potential ecological carrying capacity for the Mexican wolf based exclusively on ungulate prey biomass estimated from camera trap surveys. In the United States, the potential density estimate is high (21.4–52.7 wolves/1,000 km2) owing to the presence and relatively high densities of elk, mule deer, and white‐tailed deer.

Phylogeography ofPeromyscus schmidlyi: an endemic of the Sierra Madre Occidental, Mexico [PDF]

open access: yesJournal of Mammalogy, 2014
Peromyscus schmidlyi is an endemic rodent from the forested highlands of the Sierra Madre Occidental (SMO) in Mexico. Using 2 genetic markers (cytochrome-b and D-loop) we explored the possible relationship between a recently proposed division of pine–oak forests of the SMO into specific regional communities and patterns of genetic and morphometric ...
