Persistent Genomic Erosion in Whooping Cranes Despite Demographic Recovery. [PDF]

Mol Ecol
ABSTRACT Integrating in‐situ (wild) and ex‐situ (captive) conservation efforts can mitigate genetic diversity loss and help prevent extinction of endangered wild populations. The whooping crane (Grus americana) experienced severe population declines in the 18th century, culminating in a collapse to ~20 individuals by 1944.

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.

Spatial and temporal predictions of whooping crane (Grus americana) habitat along the US Gulf Coast

Conservation Science and Practice, 2022
The challenge of conserving viable habitat while simultaneously predicting how land cover may geographically shift with future climate change has put pressure on ecologists and policy‐makers to develop near‐term (several years to a decade) ecological and

Anatomical bases of sex- and size-related acoustic variation in herring gull alarm calls [PDF]

, 2014
The hypothesis that anatomical or physiological factors can constrain the production of vocalizations is supported by an increasing number of examples from a range of taxa, where acoustic variation is related to sex, body-size or condition. In this study,

Differential shortstopping behaviour in Whooping Cranes: Habitat or social learning?

Global Ecology and Conservation, 2023
Many migratory bird species have begun shifting their wintering grounds closer to their breeding grounds, shortening their yearly migration distance through a behavior called shortstopping.

Differential changes in the onset of spring across US National Wildlife Refuges and North American migratory bird flyways. [PDF]

PLoS ONE, 2018
Warming temperatures associated with climate change can have indirect effects on migratory birds that rely on seasonally available food resources and habitats that vary across spatial and temporal scales.

Balancing future renewable energy infrastructure siting and associated habitat loss for migrating whooping cranes

Frontiers in Ecology and Evolution, 2022
The expansion of human infrastructure has contributed to novel risks and disturbance regimes in most ecosystems, leading to considerable uncertainty about how species will respond to altered landscapes.

Avian cerebellar floccular fossa size is not a proxy for flying ability in birds [PDF]

, 2013
Extinct animal behavior has often been inferred from qualitative assessments of relative brain region size in fossil endocranial casts. For instance, flight capability in pterosaurs and early birds has been inferred from the relative size of the ...

Recovery of the whooping crane Grus americana

Biological Conservation, 1988
Abstract Officially listed as ‘endangered’, the whooping crane Grus americana currently receives strong legal protection under the Endangered Species Act of 1973. To remove it from endangered status, the official Whooping Crane Recovery Plan requires 40 nesting pairs in the main population which migrates from Wood Buffalo National Park, NWT, Canada ...
