Methods in Ecology and Evolution, EarlyView.Abstract Effective research and monitoring requires accurate, interoperable and representative data. Stereo‐video based methods are commonly used to survey fish and are rapidly expanding globally due to their cost‐effectiveness, ability to provide accurate body size measurements, non‐destructive approach and capacity to create permanent data records ...

Challenges of Monitoring Endangered Bryde's Whales During a Period of Rapid Environmental Change
Animal Conservation, EarlyView.Estimating population size is challenging for rare and elusive species that occur at low densities and are difficult to detect during sampling. We estimated the abundance of a Nationally critical whale species—Aotearoa New Zealand Bryde's whales—using a custom‐formulated POPAN model which incorporated transience to account for their complex residency ...

Interactions of Mucus Monosaccharides and the Epidermal Microbiome in Four Benthic Elasmobranchs. [PDF]
Environ Microbiol RepHere we collected mucus and microbes from the skin of Elasmobranchs to identify interactions between mucus and the microbial community. We identified key microbial genes involved in the metabolism of mucus carbohydrates in Elasmobranchs. ABSTRACT Epidermal mucus is a complicated mixture of macromolecules which acts as the first line of defence for ...

Polarization over the priority of political problems
American Journal of Political Science, EarlyView.Abstract What drives ideological division about political problems? When prioritizing which problems are most in need of redress, voters might disagree about the severity of individual outcomes that constitute such problems; the prevalence of those problems; or whether such problems are amenable to solution by government action. We field a large survey
