Timothy Bargar, Chad Anderson, Anthony Sowers
2020, Archives of Environmental Contamination and Toxicology (79) 233-245
Natural resource managers are concerned about the impacts of aerial ultra-low volume spray (ULV) of insecticides for mosquito control (i.e., mosquito adulticides) and seek science-driven management recommendations that reduce risk but allow vector control for nearby human populations. Managers at the National Key Deer Refuge (Florida Keys, FL) are concerned...
The abundance of Greater Sage-Grouse as a proxy for the abundance of sagebrush-associated songbirds in Wyoming, USA
Jason D. Carlisle, Anna D. Chalfoun
2020, Avian Conservation and Ecology (15)
Surrogate-species concepts are prevalent in animal conservation. Such strategies advocate for conservation by proxy, wherein one species is used to represent other taxa to obtain a conservation objective. The efficacy of such approaches has been rarely assessed empirically, but is predicated on concordance between the surrogate and sympatric taxa in...

2020, Journal of Environmental Management (264)
Regime shifts –persistent changes in the structure and function of an ecosystem - are well-documented in many ecosystems but remain poorly understood in floodplain-river ecosystems. We apply a resilience perspective to large floodplain-river ecosystems by presenting three examples of plausible sets of alternate regimes that are relevant to natural resource...
Proposed species extinction target fails to capture the diversity in biodiversity
David O'Brien, Margaret Hunter, Martin Breed, Laura Bertola, Rob Ogden, Clarisse Palma da Silva, Ivan Paz-Vinas, Gernot Segelbacher, Sean M. Hoban, Rodolfo Jaffe
2020, Science (368) 1193-1195
We believe the 20 species extinction metric is a retrograde proposal, which does not adequately consider the lessons learnt from the 2020 Aichi Biodiversity Targets. Whilst having a single simple overarching target is appealing, we believe a positively-framed target will garner support, rather than one that aims to, at best,...
