What makes a host profitable? Parasites balance host nutritive resources against immunity [PDF]

, 2008
Numerous host qualities can modulate parasite fitness, and among these, host nutritive resources and immunity are of prime importance. Indeed, parasite fitness increases with the amount of nutritive resources extracted from the host body and decreases ...

Variation in innate immunity in relation to ectoparasite load, age and season : a field experiment in great tits (Parus major) [PDF]

, 2010
It remains largely unknown which factors affect the innate immune responses of free-living birds. Nevertheless, the degree of innate immunity may play a crucial role in an individual's survival as it procures the first defence against pathogens.

Complex interactions within the ectoparasite community of the eastern rock sengi (Elephantulus myurus)

International Journal for Parasitology: Parasites and Wildlife, 2015
Concomitant infection with more than one parasite species is the rule in nature. Since co-infecting parasites are exploiting the same host, interspecific interactions at the infracommunity level are likely. The nature of such interactions can be expected

The spatial ecology of free-ranging domestic pigs (Sus scrofa) in western Kenya [PDF]

, 2013
Background In many parts of the developing world, pigs are kept under low-input systems where they roam freely to scavenge food. These systems allow poor farmers the opportunity to enter into livestock keeping without large capital investments.

Water bathing alters the speed-accuracy trade-off of escape flights in European starlings [PDF]

, 2009
Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings'
