Global movement patterns of migratory birds illustrate their fascinating physical and
physiological abilities to cross continents and oceans. During their voyages, most birds land …

Birds are vulnerable to petroleum pollution, and exposure has a range of negative effects
resulting from plumage fouling, systemic toxicity, and embryotoxicity. Recent research has …

Night-migratory songbirds are remarkably proficient navigators. Flying alone and often over
great distances, they use various directional cues including, crucially, a light-dependent …

Polyphenolic compounds have a variety of functions in plants including protecting them from
a range of abiotic and biotic stresses such as pathogenic infections, ionising radiation and …

The high metabolic activity associated with endurance flights and intense fuelling of migrant
birds may produce large quantities of reactive oxygen species, which cause oxidative …

Migration, a bird's metabolic apex, depends primarily on the liver and muscle for fuel
mobilization and endurance flight. In migratory redheaded buntings, adaptive increase in …

Mercury is a global pollutant that has been widely shown to adversely affect reproduction
and other endpoints related to fitness and health in birds, but almost nothing is known about …

Simple Summary Cachexia occurs in up to 80% of patients with cancer. Although cancer-
associated cachexia dramatically decreases overall survival and quality of life, it is often …

Animals dynamically adjust their physiology and behavior to survive in changing
environments, and seasonal migration is one life stage that demonstrates these dynamic …

Chronic, low‐intensity parasite infections can reduce host fitness through negative impacts
on reproduction and survival, even if they produce few overt symptoms. As a result, these …
