Spatial‐Temporal Pore Pressure and Stress Evolution Associated With the Impoundment of Two Contiguous Reservoirs in Jinsha River, China and Regional Seismicity

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 8, August 2025.
Abstract The Xiluodu‐Xiangjiaba Cascade Reservoirs have been built in the lower reaches of the Jinsha River, Yunnan Province, China since 2012. Following the impoundment of these two contiguous reservoirs, widely felt seismicity has been recorded along the mainstream of the river, including three events with magnitudes greater than 4.5.

Genomic Signals of Local Adaptation Associated With Environmental Variables in Eleginops maclovinus From Northern Chilean Patagonia

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Studying evolutionary processes in the unique and understudied Patagonian fjord ecosystem is a challenging task for evolutionary ecologists. Genomic signals of local adaptation are present in a species from northern Chilean Patagonia. Polygenic selection drives local adaptation in Eleginops maclovinus. ABSTRACT Understanding the evolutionary mechanisms

Shotgun metagenomic sequencing from Manao-Pee cave, Thailand, reveals insight into the microbial community structure and its metabolic potential [PDF]

BMC Microbiology, 2019
Due to the cave oligotrophic environment, this habitat presents a challenge for microorganisms to colonize and thrive. However, it has been well documented that microorganisms play important roles in cave development. Survival of microbes in this unique habitat likely involves a broad range of adaptive capabilities.

Anthropogenic disturbances alter the trophic niche structure and ecological relationships of understory bat communities in the Ecuadorian Andean Chocó

Wildlife Biology, Volume 2025, Issue 3, May 2025.
Human disturbances have reduced the three basic niche dimensions for the survival of some mammalian species (space, time, and resources). Anthropic activities cause the extinction of ecological functionalities faster than species extinctions. In this study, we identified four types of habitats in the Ecuadorian Andean Chocó: primary forest (PF ...

120 Years of “Lemurology”: What has Changed?

Biotropica, Volume 57, Issue 2, March 2025.
Lemurology, or the study of lemurs, is a dynamic field, exploring major topics and involving diverse scientists. We reviewed scientific articles about Lemurs from 1900 to 2022 and reported how studied topics and taxa, publication languages, authorship, and study sites changed over time. We comment on how the French colonization of Madagascar has shaped

De Novo Genome Assembly for an Endangered Lemur Using Portable Nanopore Sequencing in Rural Madagascar

Ecology and Evolution, Volume 15, Issue 1, January 2025.
Lemurs in Madagascar are under severe threat from human activities, and while advancements in genomic sequencing offer promises for conservation, disparities in global sequencing capabilities often lead to samples being sent to the Global North, perpetuating inequalities in research access and training.
