Immunocompetence, developmental stability and wingspot size in the damselfly Calopteryx splendens L.
TLDR
The results suggest that the size of wingspot is an indicator of male quality in C.splendens, and the nylon implant encapsulation rate was positively correlated with the density of haemocytes in the haemolymph. Expand
Condition dependence of pheromones and immune function in the grain beetle Tenebrio molitor
TLDR
The results show that pheromones are condition-dependent signals, the quantity of which females use in their mate choice, and the production of the phersomones is affected by the condition of the male. Expand
Interspecific aggression and character displacement in the damselfly Calopteryx splendens
TLDR
It is suggested that interspecific aggression may have caused character displacement in wing spot size of Calopteryx splendens, because the intensity of aggression towards large‐spotted males is likely to increase with relative abundance of C. virgo males. Expand
Distribution and habitat selection of wintering birds in urban environments
TLDR
Habitat selection of wintering land-birds was studied in 31 human settlements in Finland and three corvid species populations, P. domesticus and Columba livia domestica were positively related to human population density and the omnivorous diet of these species was a possible reason for their success in urban environments. Expand
Founder population size and number of source populations enhance colonization success in waterstriders
TLDR
It is demonstrated clearly that both the larger propagule size and the high number of source populations have positive effects on the probability of colonizing a new stream, and it may be essential to consider also the diversity of genetic origin for colonization success. Expand
Predation Risk Influences the Use of Foraging Sites by Tits
TLDR
It seems that predation risk in addition to interspecific competition influences the use of foraging sites by tits in coniferous forest. Expand
Biogeographical comparison of winter bird assemblages in urban environments in Finland
We studied biogeographical variation of urban bird assemblages in Finland. Winter birds were censused by single-visit study plot method from thirty-one centres of villages or towns along 950 kmExpand
Hybridization in Calopteryx damselflies: the role of males
TLDR
The data on the number of hybrids sired by either species in the wild are congruent with the results of the discrimination experiment, supporting the conclusion that males may be responsible for the hybridization. Expand
AVIAN PREDATION RISK MODIFIES BREEDING BIRD COMMUNITY ON A FARMLAND AREA
TLDR
The conclusion is that predation risk influences habitat selection of small migratory species in open habitats where scarce vegetative cover gives little protection. Expand
Do pheromones reveal male immunocompetence?
TLDR
It is shown that female mealworm beetles (Tenebrio molitor) prefer pheromones from males with better immunocompetence, indicated by a faster encapsulation rate against a novel antigen, and higher levels of phenoloxidase in haemolymph. Expand
