Hunting and fishing harvest data collection: a horizon scanning exercise from the French context

Wildlife Biology, EarlyView.
Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed

Urban bats show dietary flexibility in aquatic arthropod consumption at urban and rural waterbodies

Wildlife Biology, EarlyView.
Urban waterbodies are critical for biodiversity and provide feeding grounds for insectivorous bats. Yet, how urbanisation affects bats' food choices at urban waterbodies and the role of emergent aquatic arthropods remain poorly understood. We compared the diet of three urban bat species – Vespadelus vulturnus, Chalinolobus gouldii,and Myotis macropus –

Captive breeding cannot sustain migratory Asian houbara Chlamydotis macqueenii without hunting controls [PDF]

, 2018
To evaluate the potential contribution of captive breeding to the conservation of exploited migratory Asian houbara Chlamydotis macqueenii, we estimated release numbers required to stabilise a population in a hunting concession (14,300 km2), under ...

Population trends of dabbling ducks wintering in the alluvial valleys of Arkansas and Mississippi

Wildlife Biology, EarlyView.
Population abundances, distributions, and compositions across a diversity of taxa are changing, partly as a consequence of human‐induced global modifications. Although linking population fluctuations to anthropogenic‐induced alterations can be challenging, it is increasingly clear that long‐term monitoring is critical to understanding changing ...

The State of Migratory Landbirds in the East Asian Flyway: Distributions, Threats, and Conservation Needs

Frontiers in Ecology and Evolution, 2021
With nearly 400 migratory landbird species, the East Asian Flyway is the most diverse of the world’s flyways. This diversity is a consequence of the varied ecological niches provided by biomes ranging from broadleaf forests to arctic tundra and ...
