Animals' abilities to fly long distances and dive to profound depths fascinate earthbound
researchers. Due to the difficulty of making direct measurements during flying and diving …

The rise of antibiotic resistance demands the acceleration of molecular diversification
strategies to inspire new chemical entities for antibiotic medicines. We report here on the …

Migratory species can experience limiting factors at different locations and during different
periods of their annual cycle. In migratory birds, these factors may even occur in different …

Currently, the deployment of tracking devices is one of the most frequently used approaches
to study movement ecology of birds. Recent miniaturization of light‐level geolocators …

Radio-transmitters and light-level geolocators are currently small enough for use on
songbirds weighing< 15 g. Various methods are used to attach these markers to larger …

Abstract Semipalmated Sandpiper (Calidris pusilla) populations have undergone significant
declines at core nonbreeding sites in northeastern South America. Breeding populations …

Abstract Golden-winged Warblers (Vermivora chrysoptera) are Nearctic–Neotropical
migrants experiencing varied regional population trends not fully explained by breeding …

Miniaturized data loggers have revolutionized the study of animal movement. However, data
obtained from tagging could be compromised by impacts on animal welfare and behavior …

Background Geolocators are useful for tracking movements of long-distance migrants, but
potential negative effects on birds have not been well studied. We tested for effects of …

Archival geolocators have transformed the study of small, migratory organisms but analysis
of data from these devices requires bias correction because tags are only recovered from …
