Accounting for animal movement during aerial imaging surveys

Remote Sensing in Ecology and Conservation, EarlyView.
Animals are not stationary during aerial surveys; if their movements are related to the movement of the aerial platform, then bias can be introduced into subsequent population count estimates. We sought to establish a framework for assessing the impacts of animal movement on count error and platform bias by comparing aggregated counts and relative ...

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

Using citizen science data to inform the relative sensitivity of waterbirds to natural versus human‐dominated landscapes in China

Ecology and Evolution, 2020
Habitat loss is widely regarded as one of the most destructive factors threatening native biodiversity. Because migratory waterbirds include some of the most globally endangered species, information on their sensitivity to landscape would benefit their ...

Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

Wildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

A Monte Carlo-augmented geographical random forest approach for spatial biodiversity modeling: managing bird communities in small urban wetlands

Ecological Informatics
Small urban wetlands face intensifying pressures from rapid urbanization, yet their biodiversity patterns remain underexplored due to data scarcity and spatial complexity.

Using programmable infusion pump in avian species – a validation methodology in geese

Wildlife Biology, EarlyView.
Wildlife face anthropogenic and natural stressors that affect their physiology and behaviour. The activity of the hypothalamic–pituitary–adrenal axis and glucocorticoid (GC) production is intrinsically linked with energy regulation and environmental stressors.

Spatiotemporal Assessment of Littoral Waterbirds for Establishing Ecological Indicators of Mediterranean Coastal Lagoons

ISPRS International Journal of Geo-Information, 2017
Waterbirds are vital indicators of anthropogenic influence on the ecological status of Mediterranean coastal lagoons. Our study relates temporal waterbird data to key environmental gradients at catchment scale that have a structural or functional ...
