Species Limits and Hybridization in Andean Leaf‐Eared Mice (Phyllotis)
Ecology and Evolution, Volume 15, Issue 7, July 2025.Diversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,

The Early Evolution of a Young Normal Fault in the Aysén Fjord, Chile
Tectonics, Volume 44, Issue 7, July 2025.Abstract Seismic reflection data have been used to investigate the evolution of faults in oil and gas basins for decades and typically image deeply buried faults at low resolution, with biostratigraphic age control to date horizons at scales of 10 Myr.

Parsimonious machine learning for the global mapping of aboveground biomass potential
Ecography, Volume 2025, Issue 7, July 2025.Advances in computational power and methods, and the widespread availability of remote sensing data have driven the development of machine learning models for estimating global carbon storage. Current models often rely on dozens of predictor variables to estimate aboveground biomass density (AGBD), resulting in accurate but complex models that are ...

Paleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.Abstract The Miocene Epoch (23.03–5.33 Ma) is receiving increased attention because estimated pCO2 and its associated warmth is comparable to projections over the next century. Well‐constrained sea‐surface temperatures in the tropics and northern latitudes express amplified warming during the Miocene Climatic Optimum (MCO; 16.9–14.7 Ma), yet data from ...

Phylogeographic Structure of the Fossorial Long-Clawed Mouse Chelemys macronyx (Cricetidae: Sigmodontinae) [PDF]
, 2011 We present a phylogeographic study of the fossorial sigmodontine mouse Chelemys macronyx. Analyses were based on mitochondrial DNA sequences of specimens collected over most of distributional range of the species. Results showed that C.

Writing in community: Relationship building and accountability in knowledge production
American Anthropologist, Volume 127, Issue 2, Page 319-338, June 2025.Abstract As anthropology reckons with its past, present, and future, anthropologists increasingly seek to challenge inequities within the discipline and academia more broadly. Anthropology, regardless of subdiscipline, is a social endeavor. Yet research often remains an isolating (though not necessarily solitary) process, even within research teams and
