Roadkill patterns in Latin American birds and mammals
Global Ecology and Biogeography, Volume 31, Issue 9, Page 1756-1783, September 2022., 2022 Abstract Aim Roads are a major threat for wildlife, degrading habitat and causing mortality via wildlife–vehicle collisions. In Latin America, the conjunction of high biodiversity and a rapidly expanding road network is reason for concern. We introduce an approach that combines species traits and habitat preferences to describe vulnerability and map ...

Journal of Applied Ecology, Volume 58, Issue 11, Page 2361-2370, November 2021., 2021 Our study indicates that large herbivores have moderate yet critical effects on slowing down community change and diversity loss of highly diverse plant communities, thus suggesting that the conservation of (and potentially trophic rewilding with) large herbivores is a fundamental nature‐based solution for averting the global collapse of the ...

BJS Open, Volume 4, Issue 5, Page 830-839, October 2020., 2020 Laparoscopic subtotal gastrectomy (LSG) is associated with good perioperative outcomes and superior quality of life compared with the open approach to resection of gastric adenocarcinoma, albeit at higher cost. A cost–effectiveness analysis comparing the two approaches found LSG to be cost‐effective compared with the open approach, with an incremental ...
