Scale of herpetofauna mitigation translocation in British Columbia, Canada

The Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
Mitigation translocation is widely used across British Columbia to move amphibians and reptiles away from development. Reviewing permits from 2019–2022, we found that more than 5 million individuals, mostly larval western toads, were relocated. Yet almost no monitoring occurs, leaving outcomes unknown.

Crystal structure and functional characterization of an Asp49 phospholipase A2 from the bushmaster (Lachesis muta)

Acta Crystallographica Section F, Volume 82, Issue 5, Page 150-159, May 2026.
The crystal structure of an Asp49 phospholipase A2 from L. muta is reported, revealing a tetrameric assembly, catalytic conservation and a polarized electrostatic surface potentially linked to membrane targeting.Snake‐venom phospholipases A2 (PLA2s) are small, structurally conserved enzymes that contribute significantly to the pathophysiology of ...
