Hugo Rafael Soares Ferreira, Auteur ; José A. Alves, Auteur ; Frédéric Jiguet, Auteur ; Olivier Duriez, Auteur ; Thomas Blanchon, Auteur ; Tamar Lok, Auteur ; Jocelyn Champagnon, AuteurThroughout their annual cycle and life stages, animals depend on a variety of habitats to meet their vital needs. However, habitat loss, degradation, and fragmentation are making it increasingly difficult for mobile species such as birds to find[...]

Hugo Rafael Soares Ferreira, Auteur ; Jocelyn Champagnon, Auteur ; José A. Alves, Auteur ; Tamar Lok, AuteurWhen wintering at different sites, individuals from the same breeding population can experience different conditions, with costs and benefits that may have implications throughout their lifetime. Using a dataset from a longitudinal study on Eura[...]

Thomas Oudman, Auteur ; Petra de Goeij, Auteur ; Theunis Piersma, Auteur ; Tamar Lok, AuteurDans Ardea (105(2) 2017)It has been suggested that in most colony-breeding birds, food availability in the feeding areas surrounding the colonies limits, and thereby regulates, population size. However, population size is also determined by adult survival, which will a[...]

Article
Tamar Lok, Auteur ; Linde Veldhoen, Auteur ; Otto Overdijk, Auteur ; Joost M. Tinbergen, Auteur ; Theunis Piersma, Auteur* Migration is a widespread phenomenon in the animal kingdom. On the basis of the considerable variation that exists between and within species, and even within populations, we may be able to infer the (age- and sex-specific) ecological trade-of[...]

Soloviev, Auteur ; Theunis Piersma, Auteur ; Marcel Klaassen, AuteurReductions in body size are increasingly being identified as a response to climate warming. Here we present evidence for a case of such body shrinkage, potentially due to malnutrition in early life. We show that an avian long-distance migrant (r[...]

Jutta Leyrer, Auteur ; Tamar Lok, Auteur ; Maarten Brugge, Auteur ; Bernard Spaans, Auteur ; Brett K. Sandercock, Auteur ; Theunis Piersma, AuteurEstimates of seasonal mortality for long-distance migrant birds are extremely challenging to collect and consequently reports are scarce.
