| post-breeding dispersal of frigatebirds increases their exposure to mercury. | migration and dispersal can expose wildlife to threats in different parts of their range, particularly for localized anthropogenic threats. wildlife exposure to metal contaminants may correlate with local anthropogenic emissions. feather mercury concentrations of adult and juvenile lesser frigatebirds (fregata ariel) and great frigatebirds (f. minor) were determined for individuals breeding in the eastern indian ocean. low mercury concentration in juveniles relative to adults, higher mercury con ... | 2017 | 28377135 |
| interpopulation resource partitioning of lesser frigatebirds and the influence of environmental context. | conspecific individuals inhabiting nearby breeding colonies are expected to compete strongly for food resources owing to the constraints imposed by shared morphology, physiology, and behavior on foraging strategy. consequently, colony-specific foraging patterns that effectively partition the available resources may be displayed. this study aimed to determine whether intraspecific resource partitioning occurs in two nearby colonies of lesser frigatebirds (fregata ariel). a combination of stable i ... | 2016 | 28031809 |
| trace element concentrations in feathers from three seabird species breeding in the timor sea. | mobile marine predators, such as seabirds, are frequently used as broad samplers of contaminants that are widespread in the marine environment. the timor sea off remote western australia is a poorly studied, yet rapidly expanding area of offshore development. to provide much needed data on contamination in this region, we quantified trace element concentrations in breast feathers of three seabird species breeding on bedout island. while adult masked boobies sula dactylatra exhibited some of the ... | 2020 | 32056652 |
