Distributing transmitters to maximize population-level representativeness in automated radio telemetry studies of animal movement

Movement Ecology, 2023
Telemetry is a powerful and indispensable tool for evaluating wildlife movement and distribution patterns, particularly in systems where opportunities for direct observation are limited. However, the effort and expense required to track individuals often

Flock Size Predicts Niche Breadth and Focal Wintering Regions for a Rapidly Declining Boreal-Breeding Passerine, the Rusty Blackbird

Diversity, 2021
Once exceptionally abundant, the Rusty Blackbird (Euphagus carolinus) has declined precipitously over at least the last century. The species breeds across the Boreal forest, where it is so thinly distributed across such remote areas that it is extremely ...

Feather growth rate and mass in nearctic passerines with variablemigratory behavior and molt pattern [PDF]

, 2012
Bird species vary greatly in the duration of their annual complete feather molt. However, such variation is not well documented in birds from many biogeographic areas, which restricts our understanding of the diversification of molt strategies.

Molecular epidemiology and population genomics of tet(X4), blaNDM or mcr-1 positive Escherichia coli from migratory birds in southeast coast of China

Ecotoxicology and Environmental Safety, 2022
The emergence of multidrug-resistant (MDR) bacteria harboring tet(X4), blaNDM or mcr-1 posed a serious threat to public health. Wild birds, especially migratory birds, were considered as one of important transmission vectors for antibiotic resistance ...

Modeling highly pathogenic avian influenza transmission in wild birds and poultry in West Bengal, India. [PDF]

, 2013
Wild birds are suspected to have played a role in highly pathogenic avian influenza (HPAI) H5N1 outbreaks in West Bengal. Cluster analysis showed that H5N1 was introduced in West Bengal at least 3 times between 2008 and 2010.
