Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Stop Using Limiting Stimuli as a Measure of Sensitivities of Energetic Materials

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Accurately estimating the sensitivity of explosive materials is a potentially life‐saving task that requires standardised protocols across nations. One of the most widely applied procedures worldwide is the so‐called ‘1‐In‐6’ test from the United Nations (UN) Manual of Tests in Criteria, which estimates a ‘limiting stimulus’ for a material. In

Exploring sources of uncertainty in the estimate of waterfowl harvest in the United Kingdom

open access: yesWildlife Biology, EarlyView.
There is an urgent need to gather data on harvest rates of waterbirds in Europe to assess the sustainability of hunting. Estimates of total waterbird harvest in the United Kingdom (UK) and the relative harvest of different huntable species come from two separate surveys, the Value of Shooting (PACEC 2014) and National Gamebag Census (NGC), and these ...

Lead from Spent Ammunition: a Source of Exposure and Poisoning in Bald Eagles

open access: yesHuman-Wildlife Interactions, 2017
Ongoing occurrence of elevated levels of lead in bald eagles (Haliaeetus leucocephalus) following the ban on lead shot for waterfowl hunting led us to hypothesize that spent lead from ammunition, which is present in field residues of white-tailed deer ...
