Differences in diet‐tissue discrimination factors before and after the diet switch may mean that toward the end of the experiment, some of the nutrients for blood synthesis had been coming from stores, and repeated measures mixed models provided evidence that increases in metabolic rate might accelerate fractional turnover rates in blood.
Diet studies of seabirds: a review and recommendations
To enhance comparability of findings among studies, species, and oceanographic regions, a recommendation on standards for the reporting of results in the literature is made.
Assortative Mating as a Mechanism for Rapid Evolution of a Migratory Divide
It is shown that recently evolved allopatric wintering populations of European blackcaps Sylvia atricapilla pair assortatively on their sympatric breeding grounds, describing an important process in the evolution of migratory divides, new migration routes, and wintering quarters.
Birds as monitors of pollutants
- R. Furness
- Environmental Science
Several authors of books on the monitoring of pollution have advocated the use of animals as monitors in terrestrial and aquatic environments (e.g. Phillips, 1980; Schubert, 1985). Such studies tend…
Using bird feathers to measure mercury in the environment: Relationships between mercury content and moult
Global Seabird Response to Forage Fish Depletion—One-Third for the Birds
A threshold in prey abundance is identified below which seabirds experience consistently reduced and more variable productivity and provides an indicator of the minimal forage fish biomass needed to sustain seabird productivity over the long term.
Natural temperature regimes for loggerhead and green turtle nests in the eastern Mediterranean
The temperature differences within the clutch were larger in loggerhead than in green turtle nests, and the mean temperature over the entire incubation period is not a good indicator of sex ratio but can be used to predict the duration of incubationperiod.
Seabirds as monitors of the marine environment
Many studies have shown that seabirds are sensitive to changes in food supply, and therefore have potential as monitors of fish stocks. For most seabird species breeding parameters suitable for…
Amounts of discards by commercial fisheries and their significance as food for seabirds in the North Sea
A forensic approach to understanding diet and habitat use from stable isotope analysis of (avian) claw material
It is suggested that claws may offer a unique combination of attributes to the isotope ecologist: they are non-invasively sampled; metabolically inert but grow continuously, and are therefore a more flexible tool than feathers.
