Handheld Thermal Devices Can Facilitate Population Monitoring of the Critically Endangered Delacour's Langur Trachypithecus delacouri in Difficult Terrains

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study demonstrates that handheld thermal devices can effectively complement traditional ground‐based surveys for monitoring the critically endangered Delacour's langur in northern Vietnam. Fieldworks also revealed a population increase and reduced survey effort, highlighting thermal handhelds as a practical alternative amid drone flight ...

Borehole seismic methods for opencast coal exploration [PDF]

open access: yes, 1990
Surface seismic techniques lack the resolution to image the top 100m or so of the earth's surface necessary for opencast coal exploration. The work reported in this thesis is the development of borehole seismic methods making use of the closely spaced ...

Male Copulatory Structures in Reproductively Functional Female Live‐Bearing Fish Pseudopoecilia fria

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We recently discovered a population of the live‐bearing fish Pseudopoecilia fria (Cyprinodontiformes: Poeciliidae), in which females were found to possess gonopodia, reproductive organs normally exclusive to male fish that are used in the transfer of sperm in mating.

Comparing acoustic and visual monitoring methods for assessing biodiversity and distributions of Arctic‐breeding shorebirds

open access: yesJournal of Applied Ecology, Volume 63, Issue 2, February 2026.
Our findings demonstrate that ARUs can effectively monitor shorebird species presence, offering advantages in temporal coverage and synchronous data collection across large spatial extents. This may be particularly important in remote regions where traditional monitoring approaches are challenging to implement and sustain. Abstract The rapid decline of
