Monitoring whooping crane abundance using aerial surveys: Influences on detectability [PDF]

Wildlife Society Bulletin, 2014
The whooping crane (Grus americana), an endangered species, has been counted on its winter grounds in Texas, USA, since 1950 using fixed‐wing aircraft. Many shortcomings of the traditional survey technique have been identified, calling into question its ...

Age-Specific Survival Estimation of a Eurasian Crane Population Highlights a Long-Term Decline in Juvenile Survival. [PDF]

Ecol Evol
The Eurasian crane (Grus grus), a symbol of conservation success in Europe, has made an impressive recovery. However, our results show that over the study period, juvenile survival declined by almost 30% overall, while sub‐adults experienced a smaller decrease, and adults showed no change.

Deciphering Cryptic Population Structure in Western Sandhill Crane Subspecies (<i>Antigone canadensis</i>) of the Pacific Flyway. [PDF]

Ecol Evol
Sandhill Crane populations of the Pacific Flyway are made up of breeding populations nesting west of the Rocky Mountains, and isolated by intermediate mountain ranges. Here, we analyze microsatellite markers, mitochondrial DNA sequences, and mitochondrial haplogroups to elucidate population genetic structure and found substantial genetic ...

Avian influenza overview September-November 2025. [PDF]

EFSA J
Abstract Between 6 September and 28 November 2025, 2896 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (442) and wild (2454) birds in 29 countries in Europe. The magnitude and geographical extent of these detections were unprecedented for this time of the year, particularly in wild birds.

Diurnal habitat selection of migrating Whooping Crane in the Great Plains

Avian Conservation and Ecology, 2019
Available stopover habitats with quality foraging opportunities are essential for migrating waterbirds, including Whooping Crane (Grus americana). Several studies have evaluated habitats used by Whooping Crane for roosting throughout its migration ...

Gastrointestinal parasites of a reintroduced semi-wild plains bison (Bison bison bison) herd: Examining effects of demographic variation, deworming treatments, and management strategy

International Journal for Parasitology: Parasites and Wildlife, 2021
Bison (Bison spp) are being reintroduced into semi-wild, spatially constrained herds across North America and Europe. Herd managers are concerned about gastrointestinal (GI) nematode parasites as they care for the health of their bison.

Assessing the hydroregime of an archetypal riverine wet meadow in the central Great Plains using time‐lapse imagery

Ecosphere, 2021
Wet meadows are a declining and increasingly degraded ecosystem type. They contribute numerous ecosystem services, including nutrient cycling, water storage, and filtration, and provision of wildlife habitat, particularly for wetland‐dependent species ...

Dataset of the physical conditions of Green Ash (Fraxinus pennsylvanica) in riparian woodlands along the central Platte River

Data in Brief, 2018
The 2016 discovery of Emerald Ash Borer (Agrilus planipennis; EAB) in Nebraska warranted an assessment of the physical conditions of ash trees (Fraxinus spp.) across the state. Here we present a dataset of current physical conditions and spatial location
