Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

open access: yesJournal of Raman Spectroscopy, EarlyView.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

The role of geographical proximity to the October 7th, 2023, attack on Israel: Mental health disorders and related risk factors

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract The current study assessed how mental health outcomes and related risk factors varied by proximity to the October 7, 2023, attacks by Hamas among a community sample from Ofakim, a town in southern Israel. Established cutoff scores on self‐report measures of posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized ...

Predicted genetic consequences of alternative population control strategies for North American plains bison in Yellowstone National Park

open access: yesThe Journal of Wildlife Management, EarlyView.
Management of bison in Yellowstone National Park under the available strategies that maintained ≥3,500 individuals (1:1 sex ratio), removed <40% of the population at a time and prioritized relatives for removal were predicted to maintain genetic variation at levels consistent with long‐term conservation (>95% of existing variation).
