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 ...

Impact of low-protein diet on geese growth: early low-protein diets with amino acid supplementation improve nitrogen utilization and maintain growth performance in meat geese

Frontiers in Animal Science
Herein, 364 one-day-old male Jiangnan white goslings were divided into four groups: PM (18.55% crude protein (CP) + main amino acids (AA)), PA (18.55% CP + all AA), LPM (15.55% CP + main AA), and LPA (15.55% CP + all AA). The main AAs were Lys, Met, Thr,

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.

Improving the Efficiency of Wildlife Management: An Application to Waterfowl Production in the Prairie Pothole Region [PDF]

Wildlife management agencies increasingly use economic analyses to improve the efficiency of their management policies. Few economic studies consider supply-side analyses for wildlife management, due, in part, to a lack of biological response data that ...

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
