Population genetic structure of male black grouse (Tetrao tetrix L.) in fragmented vs. continuous landscapes
TLDR
The association of habitat fragmentation with genetic structure of male black grouse Tetrao tetrix and the detection of isolation by distance in the Alps suggests that gene flow among populations does occur and that habitat fragmentation can affect genetic structure in avian species with relatively high dispersal propensities.

Sindbis Virus Infection in Resident Birds, Migratory Birds, and Humans, Finland
TLDR
Resident grouse may be involved in the epidemiology of SINV in humans and its role in the regulation in humans is still poorly understood. Expand
Extra-pair paternity and male characteristics in the pied flycatcher
TLDR
It is argued that females paired with genetically dissimilar males may try to avoid the effects of extreme outbreeding by seeking extra-pair copulations (EPCs). Expand
Lack of genetic structuring and subspecies differentiation in the capercaillie (Tetrao urogallus) in Finland
TLDR
The results suggest that the Finnish capercaillie population is - or has been at least very recently - more or less continuous throughout the country. Expand
A TRADE-OFF BETWEEN CURRENT REPRODUCTION AND MOLT IN THE PIED FLYCATCHER - AN EXPERIMENT
TLDR
It is suggested that a trade-off between moult and current reproduction could be one possible mechanism causing costs of reproduction in birds. Expand
Orthomyxo-, paramyxo- and flavivirus infections in wild waterfowl in Finland
TLDR
It is concluded that circulation of both influenza A virus and avian paramyxovirus-1 in Finnish wild waterfowl was documented and antibody testing in this format seemed to be of low sensitivity. Expand
Sex and age influence intestinal parasite burden in three boreal grouse species
TLDR
Differences in growth rates and body size are potential factors that may lead to male-biased parasitism in these grouse species, and their impact requires further studies. Expand
Trypanosomes of some Fennoscandian birds
Linear measurements and derived indices of trypanosomes from species of Fennoscandian birds were compared to those reported form Trypanosoma avium, T. everetti, T. ontarioensis and T. paddae. TheExpand
Combs and sexual selection in black grouse (Tetrao tetrix)
TLDR
It is shown that supra-orbital combs in lekking black grouse (Telrao tetrix) in relation to sexual selection at five leks in Finland 1991-1998 and four leeks in Sweden 1992-1995 are influenced by sexual selection. Expand
NO EVIDENCE FOR EFFECTS OF BREEDING DENSITY AND MALE REMOVAL ON EXTRAPAIR PATERNITY IN THE PIED FLYCATCHER
TLDR
Examination of EPF in Pied Flycatchers found that older females mated with browner yearling males may have adjusted their initial mate choice through EPCs to acquire indirect genetic benefits, and females may be constrained to accept a mate of lower than preferred quality, especially at low breeding density.
