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]
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 ...

Coal Industry Impact on Ants of the Genus Formica (Hymenoptera: Formicidae)
The peculiarities of the settlement of ants of the genus Formica have been studied at the areas affected by varying degreesof impact made by enterprises of surface (opencast mines) and underground (deep mines) coal hard mining.

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

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

Soil fertility analysis in and around magnesite mines, Salem, India
The opencast mining operations have periodical effects in surrounding landscape and it is important to monitor the quality of the soil. The pre- and post-mining activities influence the soil quality due to removal of vegetation and topsoil cover. The low-
