Tissue samples are frequently collected to study various aspects of avian biology, but in many cases these samples are not used in their entirety and are stored by the collector. The already collected samples provide a largely overlooked opportunity

A fruit diet rather than invertebrate diet maintains a robust innate immunity in an omnivorous tropical songbird
Autor: Maurine W. Dietz, Chima Josiah Nwaogu, Annabet Galema, B. Irene Tieleman, Will Cresswell
Publikováno v: The Journal of Animal Ecology
Journal of Animal Ecology, 89(3), 867-883. Wiley
Diet alteration may lead to nutrient limitations even in the absence of food limitation, and this may affect physiological functions, including immunity. Nutrient limitations may also affect the maintenance of body mass and key life‐history events

Seasonal differences in baseline innate immune function are better explained by environment than annual cycle stage in a year‐round breeding tropical songbird
Autor: Maaike A. Versteegh, Chima Josiah Nwaogu, Will Cresswell, B. Irene Tieleman
Publikováno v: The Journal of Animal Ecology
Journal of Animal Ecology, 88(4), 537-553. Wiley
Seasonal variation in innate immunity is often attributed to either temporal environmental variation or to life‐history trade‐offs that arise from specific annual cycle stages but decoupling them is difficult in natural populations.Here, we effec

Local timing of rainfall predicts the timing of moult within a single locality and the progress of moult among localities that vary in the onset of the wet season in a year-round breeding tropical songbird

Funding: C.J.N. was supported by a studentship funded by the Leventis Conservation Foundation through the University of St. Andrews, UK and an Ubbo Emmius grant of the University of Groningen. Rainfall seasonality is likely an important cue for timin

Temperature and aridity determine body size conformity to Bergmann’s rule independent of latitudinal differences in a tropical environment
Autor: Chima Josiah Nwaogu, B. Irene Tieleman, Will Cresswell, Kwanye Bitrus
Publikováno v: Journal of Ornithology, 159(4), 1053-1062. SPRINGER
Journal of Ornithology
Bergmann’s rule, defined as the tendency for endotherms to be larger in colder environments, is a biophysical generalization of body size variation that is frequently tested along latitudinal gradients, even though latitude is only a proxy for temp

Breeding limits foraging time

Publikováno v: Journal of Avian Biology, 48(4), 563-569. Wiley
Funds were received from the Ubbo Emmius grant, Univ. of Groningen and also from the Univ. of St Andrews. Birds should store body reserves if starvation risk is anticipated; this is known as an ‘interrupted foraging response’. If foraging remains

Body reserves in intra-African migrants
Autor: Will Cresswell, Chima Josiah Nwaogu
Publikováno v: Journal of Ornithology, 157(1), 125-135. SPRINGER
Avian migration has been shown to be a life history strategy for surviving environmental resource variability, but it requires increased body reserves for long distance flight. Fat reserves make excellent energy stores for barrier crossing, whereas p
