- Climate change and unequal phenological changes across four trophic levels: constraints or adaptations?Christiaan Both
Animal Ecology Group, Center for Ecological and Evolutionary Studies, University of Groningen, PO Box 14, 9750 AA Haren, The Netherlands
J Anim Ecol 78:73-83. 2009..Selection on phenology could thus be both from matches of phenology with higher and lower levels, and quantifying these can shed new light on why some organisms do adjust their phenology to climate change, while others do not...

Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 14, 9750 Haren, The Netherlands

- Comment on "Rapid advance of spring arrival dates in long-distance migratory birds"Christiaan Both
Animal Ecology Group, Centre of Ecological and Evolutionary Studies, University of Groningen, Post Office Box 14, 9750AA Haren, Netherlands
Science 315:598; author reply 598. 2007..However, most migrants should not advance their migration time because the phenology of their breeding grounds has not changed. It is more likely that migration speed has changed in response to improved environmental circumstances...
- Social environment affects juvenile dispersal in great tits (Parus major)Marion Nicolaus
Animal Ecology Group Behavioural Ecology and Social Organization, Centre for Ecological and Evolutionary Studies, University of Groningen, Groningen, The Netherlands
J Anim Ecol 81:827-37. 2012..Alternatively, male territory acquisition may be facilitated by a high local density of 'candidate' males, and therefore, juveniles were less successful in settling in female-biased plots...
- Local sex ratio affects the cost of reproductionMarion Nicolaus
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 11103, 9700 CC Groningen, The Netherlands
J Anim Ecol 81:564-72. 2012..5. Our results provide the first experimental evidence that local sex ratio can affect reproductive costs and thus optimal clutch size...
- Climate change, breeding date and nestling diet: how temperature differentially affects seasonal changes in pied flycatcher diet depending on habitat variationClaudia Burger
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, Groningen, The Netherlands
J Anim Ecol 81:926-36. 2012..Such between-habitat differences can have important consequences for population dynamics and should be taken into account in studies on phenotypic plasticity and adaptation to climate change...

- Immune function in a free-living bird varies over the annual cycle, but seasonal patterns differ between yearsArne Hegemann
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, P O Box 11103, 9700 CC, Groningen, The Netherlands
Oecologia 170:605-18. 2012..Instead, fluctuating environmental conditions that vary among years likely contribute to the immunological variation that we observed...
- Sex-specific effects of altered competition on nestling growth and survival: an experimental manipulation of brood size and sex ratioMarion Nicolaus
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, Haren, The Netherlands
J Anim Ecol 78:414-26. 2009..7. We conclude that male nestlings are not likely to be more expensive to raise, yet they have a size-related competitive advantage in large broods, leading to higher mortality of their on average lighter female nest mates...
- No experimental evidence for local competition in the nestling phase as a driving force for density-dependent avian clutch sizeMarion Nicolaus
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, The Netherlands
J Anim Ecol 78:828-38. 2009..Instead, we suggest that competition acting in a different phase (e.g. before egg laying or after fledgling) was responsible for the density effect on clutch size among years...

Animal Ecology Group, Centre for Life Sciences, University of Groningen, Groningen, The Netherlands

Netherlands Institute of Ecology, PO Box 40, 6666 ZG Heteren, The Netherlands
Proc Biol Sci 270:741-7. 2003..Because this personality trait has a genetic basis, our results imply that genotypes differ in their dispersal distances. Therefore, the described patterns have profound consequences for the genetic composition of populations...
