Recent theory predicts that personality traits contributing to resource intake rates could reflect the individual's condition-dependent capacity to resist parasites and pathogens. Since females often prefer mates with strong immune defence, females could potentially gain fitness benefits by using male's behavioral type (BT) as one mate choice crite...

By conveying information of disease resistance, sexual signals may be used as cues for adaptive mate choice. Here we report observations on survival of laboratory-maintained, wild-collected, sexually mature, ready-to-spawn cyprinid fish, Rutilus rutilus (roach), under accidental epidemic attributed to Flavobacterium psychrophilum, diagnosed using s...

In this study, we investigated the effect of rapid/delayed changes in silver birch foliage quality induced by minor defoliation on gypsy moth fitness, immune function, and resistance of larvae against natural enemies. Insect fitness was estimated as pupal weight, the period of larval stage, and mortality rate. Larval immune status was detected as a...

Although it is generally recognized that immunity is costly, not much is known about how these costs are distributed among different compartments of the immune system. Using lines of Drosophila melanogaster that differed in their antibacterial innate immune response due to differences in the functional transcription factor Relish, we set out to inv...

Cercarial release from the first intermediate host is an important stage in the transmission of trematode parasites. Besides long-term (seasonal) temperature fluctuations, short-term temperature changes can also influence cercarial emergence. We tested the response of the bucephalid trematode, Rhipidocotyle fennica (R. fennica), acclimatized to 17 ...

Background. Migratory birds are often faced with the challenge of undertaking long-distance journeys while harboring parasites. Objective. I investigated the possibility that Hippoboscid flies (Diptera, Hippoboscidae), blood-feeding ectoparasites, would be associated with reduced body condition or fat reserves of migratory songbirds. Methods. I mis...
