Diversification and evolution of Hawaiian Megalagrion damselflies (Pinapinao, Odonata: Coenagrionidae) Ka Ho‘omāhuahua a me ke Kumu Ho‘omohala o nā Pinapinao Megalagrion o Hawai‘i (Odonata: Coenagrionidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
The ancestor of today's pinapinao, Hawaiian Megalagrion damselflies, diverged from Ischnurinae around 51 MA and likely evolved for over 20 MA before colonizing the Northwestern Hawaiian Islands. An ancestor of Megalagrion colonized the Northwestern Hawaiian Islands and diversified into ecological niches with four new breeding habitats and two new gill ...

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

open access: yesJournal 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

open access: yesEcology 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

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

open access: yesWildlife 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 ...
