Availability and use of natural tree holes by cavity nesting birds in a Swedish deciduous forest
TLDR
The aim of this study was to quantify the density of cavities, their characteristics, and their origination dates in trees. Expand
The effect of habitat loss on a deciduous forest specialist species: the White-backed Woodpecker (Dendrocopos leucotos)
TLDR
This study extends earlier analyses concerning range contraction and explores whether there exists a threshold in the amount of suitable habitat below which the species will not persist, and if there is a nonlinear decline in population size as suitable habitat in the forest landscape is reduced. Expand
Bioaccumulation of PCBs from Sediments by Oligochaetes and Fishes: Comparison of Laboratory and Field Studies
TLDR
Results indicate that, under the exposure regime used in this study, laboratory tests with L. variegatus can be positive for PCB bioaccumulation, and that PCB concentrations in P. promelas were consistently smaller than in any of the other species investigated. Expand
Clutch size and the costs of incubation in the pied flycatcher Ficedula hypoleuca
Etude des depenses liees a l'incubation chez le gobe mouche noir et de l'influence de la taille des couvees sur celles-ci. Des manipulations de tailles de couvee montrent que les femelles incubentExpand
Polychlorinated Biphenyls in the Great Lakes
This chapter reviews the scientific understanding of the concentrations, trends, and cycling of polychlorinated biphenyls (PCBs) in the Great Lakes. PCBs were widely used in the Great Lakes regionExpand
Genetic Structure and Variability of White‐Backed Woodpecker (Dendrocopos Leucotos) Populations in Northern Europe
The white-backed woodpecker is a highly endangered species in Sweden, with only three fragmented populations comprising a total of some ten breeding pairs. Restocking with birds from other viable pExpand
The search cost in mate choice of the pied flycatcher
TLDR
Pavlovian conditioning of signal-centred action patterns and autonomic behaviour: a chronological analysis of function, and foraging decisions in starlings (Sturnus vulgaris L.). Expand
Biometry, habitat distribution and breeding success in the Pied Flycatcher Ficedula hypoleuca
TLDR
The size-related assortment of individuals upon the two habitats was interpreted as the outcome of competitive interactions and the lower reproductive success in the less preferred habitat are in accordance with Fretwell's ideal despotic distribution model. Expand
Biogeographic patterns of the East African coastal forest vertebrate fauna
TLDR
The results suggest that the relative importance (and causal relationship) of forest attributes affecting the distribution of the East African coastal forest vertebrate fauna varies depending on life history traits such as dispersal ability and forest specialization. Expand
Winter metabolism of coniferous forest tits (Paridae) under arctic conditions: a study with doubly labeled water
Daily field metabolic rates (FMR) during mid winter of two species of coniferous forest tits, Siberian Tit Parus cinctus and Willow Tit Parus montanus were measured with the doublylabeled water (DLW)Expand
