Impacts of bat use of anthropogenic structures on bats and humans

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Human‐induced landscape modifications and climate change are forcing wildlife into closer contact with humans as the availability of natural habitats decreases. Although the importance of anthropogenic structures for the conservation of species is widely recognized, negative narratives surrounding bats may impede conservation efforts in human ...

Discovery of Fulminic Acid, HCNO, in Dark Clouds

, 2008
We report on the first detection in space of fulminic acid, HCNO. This isomer of HNCO has been observed in three starless cores, B1, L1544 and L183, and in the low mass star forming region L1527 with a measured abundance ratio of HNCO/HCNO between 40-70.

Near barrier scattering of 8He on 208Pb

EPJ Web of Conferences, 2014
The exotic nucleus 8He is investigated by means of the measurement of the angular distributions of the elastic channel and the 6He and 4He fragment yields produced in the collision with a 208Pb target at two energies around the Coulomb barrier, 16 and 22

Genetic origins and climate‐induced erosion in economically important Asian walnuts

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little
