Current methods and future directions in avian diet analysis
Identifying the composition of avian diets is a critical step in characterizing the roles of birds
within ecosystems. However, because birds are a diverse taxonomic group with equally …

[HTML][HTML] State of the art, gaps and future perspectives on common kestrel ecotoxicology
Anthropogenic activities have caused a steady decline of common kestrel (Falco
tinnunculus) since the 1980s. Effects, especially sublethal effects of contaminants, need to …

Mercury biomagnification in a Southern Ocean food web
Biomagnification of mercury (Hg) in the Scotia Sea food web of the Southern Ocean was
examined using the stable isotope ratios of nitrogen (δ 15 N) and carbon (δ 13 C) as proxies …

Stable isotopes from museum specimens may provide evidence of long-term change in the trophic ecology of a migratory aerial insectivore
Identifying the mechanisms of ecological change is challenging in the absence of long-term
data, but stable isotope ratios of museum specimen tissues may provide a record of diet and …

Coupling biogeochemical tracers with fish growth reveals physiological and environmental controls on otolith chemistry
Biogeochemical tracers found in the hard parts of organisms are frequently used to answer
key ecological questions by linking the organism with the environment. However, the …

Mercury biomagnification in an Antarctic food web of the Antarctic Peninsula
Under the climate change context, warming Southern Ocean waters may allow mercury (Hg)
to become more bioavailable to the Antarctic marine food web (ie, ice-stored Hg release and …

Seabird year-round and historical feeding ecology: blood and feather δ13C and δ15N values document foraging plasticity of small sympatric petrels
The foraging ecology of small seabirds remains poorly understood because of the difficulty
of studying them at sea. Here, the extent to which 3 sympatric seabirds (blue petrel, thin …

Seabird tissues as efficient biomonitoring tools for Hg isotopic investigations: Implications of using blood and feathers from chicks and adults
Blood and feathers are the two most targeted avian tissues for environmental biomonitoring
studies, with mercury (Hg) concentration in blood and body feathers reflecting short and long …

Seasonal and annual differences in the foraging ecology of two gull species breeding in sympatry and their use of fishery discards
Niche segregation between similar species will result from an avoidance of competition but
also from environmental variability, including nowadays anthropogenic activities. Gulls are …

High individual flexibility in the foraging behavior of a marine predator, the common murre
J Gulka, GK Davoren - Marine Biology, 2019 - Springer
The foraging ecology of breeding seabirds is largely influenced by prey availability and
energy demands related to reproduction which, in combination with other factors, can affect …
