Combining non‐invasive survey methods increases cumulative detection probability for breeding harlequin ducks Histrionicus histrionicus

Wildlife Biology, EarlyView.
The effective implementation of new technologies for wildlife population monitoring is limited by knowledge of factors that impact their efficacy. Population monitoring of harlequin ducks Histrionicus histrionicus on their breeding streams in Montana and Idaho in the Northern Rocky Mountains, has historically relied on ground‐based foot surveys (GBS ...

Estimating crippling loss from hunting with multistate models: a case study on northern bobwhites

Wildlife Biology, EarlyView.
Hunting as a recreational pursuit provides an important ecosystem service worldwide. Harvest management plays a vital role in regulating wildlife take to ensure long‐term population sustainability and meet value‐based objectives (e.g. hunter satisfaction). However, managers rarely have complete control or observability of harvest mortality.

Lower reclamation of coastal lagoon conserves higher waterbird assemblage phylogenetic diversity

Global Ecology and Conservation
Natural habitat loss caused by wetland reclamation is one of the most important causation for waterbird decline worldwide. Measurements of biodiversity loss always relied on the species and abundance reduce initially.

Fate of orphans of Canada geese harvested by hunters in Connecticut, USA, depends upon which month the parents were killed

Wildlife Biology, EarlyView.
Little is known about what happens to juvenile birds after one or both of their parents are harvested by hunters during the post‐fledging dependency period. Here, we compare the fate of juvenile Canada geese Branta canadensis that lost ≥ 1 parent to hunters (orphans) during this period to other juveniles that retained both parents (non‐orphans). For 25

Intra-annual compositions and diversity variations of waterbird communities in China

Global Ecology and Conservation
Waterbirds are often used as indicators of wetland biodiversity and ecosystem health due to their sensitivity to environmental changes. However, most studies have focused on long-term variations of waterbird communities, while the intra-annual changes ...

Ruddy Shelduck Tadorna ferruginea home range and habitat use during the non-breeding season in Assam, India [PDF]

India is an important non-breeding ground for migratory waterfowl in the Central Asian Flyway. Millions of birds visit wedands across the country, yet information on their distribution, abundance, and use of resources is rudimentary at best.

How do wintering waterbird communities respond to polder restoration in a Ramsar wetland of the Yangtze River Basin, China? A functional and phylogenetic perspective

Avian Research
Wetland restoration has been increasingly implemented to compensate for the substantial loss of natural wetlands, and consideration of multidimensional biodiversity is essential for evaluating how restoration affects the ecological functioning and ...
