De Snoo, AuteurTo help restore food availability for birds, arable field margins (extensively managed strips of land sown with grasses and forbs) have been established on European farmland. In this study we describe the effect of field margins on the diet of E[...]

Volker Salewski, Auteur ; Wesley M. Hochachka, Auteur ; Heiner Flinks, AuteurDeclining body size has been suggested to be a response of animals to global warming, but analyses of time series have led to contradictory results. One problem is that each trait related to body size may vary in response to factors other than t[...]

Irene Tieleman, Auteur ; Frank Berendse, AuteurIn recent decades, Skylark (Alauda arvensis) populations in Europe have declined sharply due to agricultural intensification. Insufficient reproduction rates are one reason. Increased winter mortality may also be important, but studies outside t[...]
Article
Heiner Flinks, AuteurPattern, extent and duration of moult as well as the influence of the hatching date in first-year birds was studied in 320 stonechats from 1991 to 1996 in Northrhine-Westfalia, Germany. The age of 60 birds could be determined exactly. 9 birds we[...]
Article
Heiner Flinks, Auteur ; Barbara Helm, Auteur ; Peter Rothery, AuteurTiming is crucial in seasonal environments. Passerine birds typically use a combination of physiological mechanisms and environmental cues to ensure that breeding, moult and migration occur without major temporal overlap and under the most favou[...]
Article
Heiner Flinks, Auteur ; Volker Salewski, AuteurWing and tail length measurements are important tools in ornithology. Amongst linear measurements, wing length has been considered to be the best indicator for body size for taxonomy and ecomorphology, as well as for studies about the impact of [...]
