Genetic background, and not ontogenetic effects, affects avian seasonal timing of reproduction by Gienapp, P., Noordwijk, A. J., Visser, M. E.

“…Avian seasonal timing is a life‐history trait with important fitness consequences and which is currently under directional selection due to climate change. To…”

Warmer springs lead to mistimed reproduction in great tits (Parus major) by Visser, M. E., Noordwijk, A. J. van, Tinbergen, J. M., Lessells, C. M.

“…In seasonal environments, the main selection pressure on the timing of reproduction (the ultimate factor) is synchrony between offspring requirements and food…”

Selection for the Timing of Great Tit Breeding in Relation to Caterpillar Growth and Temperature by Van Noordwijk, A.J., McCleery, R.H., Perrins, C.M.

“…1. We investigated the relation between the timing of great tit breeding, measured as the mean date of laying the first egg in each clutch, the timing of…”

Acquisition and Allocation of Resources: Genetic (CO) Variances, Selection, and Life Histories by de Jong, G., van Noordwijk, A. J.

“…We investigate a genetic model in which two traits result from the acquisition and allocation of a single resource. Phenotypic values for the two traits are…”

Poor reproduction in forest passerines from decline of snail abundance on acidified soils by Graveland, J, van der Wal, R, van Balen, J. H, van Noordwijk, A. J

“…It is shown that egg-shell defects and the related high incidence of clutch desertion and empty nests among forest passerines are caused by calcium deficiency…”

Nutrient or Energy Limitation on Egg Formation: A Feeding Experiment in Great Tits by NAGER, R. G, RÜEGGER, C, VAN NOORDWIJK, A. J

“…1. We tested the hypothesis that protein availability rather than energy availability constrains egg formation in great tits (Parus major L.) by providing them…”

A Method to Isolate Environmental Effects on Nestling Growth, Illustrated with Examples from the Great Tit (Parus major) by Keller, L. F., Van Noordwijk, A. J.

“…1. Fledging weight has been shown to correlate with survival in many bird species and, therefore, is an important component of fitness. Fledging weight results…”

Offspring fitness and individual optimization of clutch size by Both, Christiaan, Tinbergen, Joost M., van Noordwijk, Arie J.

“…Within–year variation in clutch size has been claimed to be an adaptation to variation in the individual capacity to raise offspring. We tested this hypothesis…”

Inbreeding in an Island Population of the Great Tit by Van Noordwijk, A. J., Scharloo, W.

“…During the long-term population study of the Great Tit, all nestlings were ringed and most parents were identified. This allows the construction of…”
