Pedro M. Lourenço, Auteur ; Theunis Piersma, AuteurMoult is an important maintenance activity that should be carefully timed within the annual cycle. Many birds perform a pre-alternate moult of body feathers some time prior to the breeding season. In migrants, the timing of the pre-alternate mou[...]

José A. Alves, Auteur ; Pedro M. Lourenço, Auteur ; Theunis Piersma, Auteur ; William J. Sutherland, Auteur ; Jennifer A. Gill, AuteurCapsule Distinct breeding populations of migratory species may overlap both spatially and temporally, but differ in patterns of habitat use. This has important implications for population monitoring and conservation. Aims To quantify the extent [...]

Valentijn Van Den Brink, Auteur ; Julia Schroeder, Auteur ; Christiaan Both, Auteur ; Pedro M. Lourenço, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Theunis Piersma, AuteurCapsule Black-tailed Godwits first return to the nest location of the previous year, even when moving to a different nest location later that season. Aims To examine the use of space by Black-tailed Godwits during the two months before egg-layin[...]

Article
Pedro M. Lourenço, AuteurRagworms Hediste diversicolor are an important prey item in the diet of many estuary birds. The standard method for estimating the number of Ragworms in faeces or pellets is simply dividing the counted number of Ragworm mandibles by two, which c[...]

Carlos D. Santos, Auteur ; Pedro M. Lourenço, Auteur ; Ana C. Miranda, Auteur ; José P. Granadeiro, Auteur ; Jorge M. Palmeirim, AuteurThe ability of investigators to study the behavior of animals at night is often limited by the difficulties of making observations in the dark, particularly at a distance. Indirect techniques, such as radio tracking, generally produce limited be[...]

Ricardo J. Lopes, Auteur ; José A. Alves, Auteur ; Jennifer A. Gill, Auteur ; Tomas G. Gunnarsson, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Pedro M. Lourenço, Auteur ; José A. Masero, Auteur ; Theunis Piersma, Auteur ; Peter M. Potts, Auteur ; Bruno Rabacal, Auteur ; Sandra Reis, Auteur ; Juan M. Sánchez-Guzmán, Auteur ; Francisco Santiago-Quesada, Auteur ; Auxiliadora Villegas, AuteurResolving the migratory connectivity (identifying non-breeding grounds) of migrating bird populations that are morphologically similar is crucial for an understanding of their population dynamics and ultimately their conservation. Such is the ca[...]
Article
José A. Alves, Auteur ; Pedro M. Lourenço, AuteurMapping migratory routes and the distribution of species during migration requires information collected over large scales (e.g.survey data), or the ability to follow specific movements (e.g. using tracking devices), which is often limited to a [...]

Lourenço, Auteur ; Ricardo C. Martins, Auteur ; Filipe Moniz, Auteur ; Sara Pardal, Auteur ; Afonso Rocha, Auteur ; Carlos D. Santos, Auteur ; Vitor Encarnacao, Auteur ; José P. Granadeiro, AuteurMigratory wader populations face global threats, mainly related to increasing rates of habitat loss and disturbance driven by human activities. To a large extent, the long-term survival of these populations requires the conservation of networks [...]

Pedro M. Lourenço, Auteur ; Rosemarie Kentie, Auteur ; Julia Schroeder, Auteur ; José A. Alves, Auteur ; Niko M. Groen, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Theunis Piersma, AuteurBetween 2005/06 and 2008/09 we studied Black-tailed Godwits Limosa I. limosa staging in the rice fields surrounding the Tejo and Sado estuaries, Portugal. Godwits were counted weekly and flocks were scanned for colour-ringed individuals. We anal[...]

Pedro M. Lourenço, Auteur ; Rosemarie Kentie, Auteur ; Julia Schroeder, Auteur ; Niko M. Groen, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Theunis Piersma, AuteurWhen early breeding is advantageous, migrants underway to the breeding areas may be time stressed. The timing of sequential events such as migration and breeding is expected to be correlated because of a "domino effect", and would be of particul[...]

Julia Schroeder, Auteur ; Theunis Piersma, Auteur ; Niko M. Groen, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Rosemarie Kentie, Auteur ; Pedro M. Lourenço, Auteur ; Hans Schekkerman, Auteur ; Christiaan Both, AuteurAdvances in mowing schedules have led to early and rapid declines in the seasonal food availability for, and survival rates of, chicks of grassland-breeding waders. Concurrently, increased levels of soil fertilization may have improved food abun[...]

Pedro M. Lourenço, Auteur ; Nuno Curado, Auteur ; Filipa Loureiro, Auteur ; Alfonso Godino, Auteur ; Eduardo Santos, AuteurSince the resources available for nature conservation tend to be very limited, localised conservation actions are often the only feasible management option. Therefore, we must select key areas where these actions will be most effective. Here we [...]

Julia Schroeder, Auteur ; Pedro M. Lourenço, Auteur ; Marco Van Der Velde, Auteur ; Jos C. E. W. Hooijmeijer, Auteur ; Christiaan Both, Auteur ; Theunis Piersma, AuteurSystematic sex-related differences in size and plumage are informative of sex-specific selection pressures. Here, we present an analysis of sexual dimorphism in body size and plumage of Black-tailed Godwits Limosa limosa limosa from a breeding p[...]
