Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Impacts of microhabitat changes on wintering waterbird populations [PDF]
, 2017 Caisang Lake, a human-modified wetland, experienced dramatic habitat alterations from the planting of lotus and culturing of crab. Whether the Caisang Lake still maintains populations of wintering waterbirds is of great concern.

Intra-annual compositions and diversity variations of waterbird communities in China
Global Ecology and ConservationWaterbirds 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 ...

Wildlife Society Bulletin, EarlyView.We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Wildlife Society Bulletin, EarlyView.Autonomous recording units (ARUs) are increasingly used for passive acoustic monitoring, but deploying them in remote or inaccessible locations remains challenging. We developed and field‐tested a lightweight, low‐cost floating platform for drone‐assisted deployment and retrieval of ARUs in wetland interiors.

Diet, phenology and body size shape nutrient release by songbirds
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

PREVALENCE OF ECHINOSTOMATIDOSIS IN WATERBIRD
Russian Electronic Scientific Journal, 2023 The article presents the results of studies on the distribution of echinostomatidosis of geese and ducks in the Republic of Bashkortostan. According to the results of the autopsy and helminthoscopic studies, the extent of infestation in geese in the foreststeppe zone of the Republic is 76,7%, in the steppe zone – 54,5%, in the mountain forest – 36,7 ...
