Antagonistic host-parasite interactions lead to coevolution of host defenses and parasite virulence. Such adaptation by parasites to host defenses may occur to the detriment of the ability of parasites to exploit alternative hosts, causing parasite specialization and speciation. We investigated the relationship between level of anti-parasite defense in hosts and taxonomic richness of two chewing louse suborders (Phthiraptera: Amblycera, Ischnocera) on birds. While Amblyceran lice tend to occur… 
Ectoparasitism and stress hormones: strategy of host exploitation, common host-parasite history and energetics matter.
The results suggest that ectoparasitism can be stressful to their hosts, however, the occurrence of parasite-induced stress seems to depend on the identity of both host and parasite species and the evolutionary history of a host-parasite association.
Differential host defense against multiple parasites in ants
It is concluded that the selection pressure on the host to evolve counter-defenses is higher for costly parasites and, thus, a hierarchical host defense strategy has evolved that depends on the parasites’ impact.
Does investment into “expensive” tissue compromise anti-parasitic defence? Testes size, brain size and parasite diversity in rodent hosts
The results cast doubt on the validity of the expensive tissue hypothesis, but suggest instead that larger testes are associated with higher parasite diversity via their effect on mobility and/or testosterone-mediated immunosuppression.
Parasite diversity: an overlooked metric of parasite pressures?
This work focuses on mammals and discusses the main limits of ‘one host/one parasite system’ approaches when estimating parasitic pressures, and gives recent arguments that support the hypothesis that parasite diversity per se exerts a strong selective pressure on hosts.
Evidence is found that brood parasitism has opposing effects on louse richness at two slightly differing macroevolutionary scales, namely the species richness and the genera richness.
Malaria infections reinforce competitive asymmetry between two Ficedula flycatchers in a recent contact zone
The results support the idea that parasites can strongly influence the outcome of interspecific competition between closely related host species, but that the invading species need not necessarily be more susceptible to local parasites.
Immunocompetence and helminth community of the white-toothed shrew, Crocidura russula from the Montseny Natural Park, Spain
The result suggests either a differential modulating effect on immunity by the two groups of worms or the existence of an antagonistic association between nematodes and cestodes mediated by the immune response of the host.
Social integration of macroparasites in ant societies: ultimate and proximate mechanisms
It is demonstrated for the first time that ant parasites are able to acquire mimetic compounds from their host, and the degree of dependency on chemical mimicry to achieve social integration differed considerably between the two parasites.


Interactions between a brood parasite and its host in relation to parasitism and immune defence
B broodparasite nestlings may outcompete host nestlings because of pathogen speciWcity, and because of their eYcient immune system mediated by their higher rate of food intake.
Immune Defense and Host Sociality: A Comparative Study of Swallows and Martins
It is shown that the impact of parasites on host reproductive success was positively associated with the degree of sociality in the bird family Hirundinidae, however, the cost of parasitism in highly colonial species was countered by high levels of T‐ and B‐cell immune responses.
Population biology of swift (Apus apus) ectoparasites in relation to host reproductive success
Host reproductive success and survival appeared to be independent of the number of lice or louse flies, and neither parasite correlated with the number, body mass, or date of fledging of young birds, nor with the overwinter survival of adults.
Reciprocal Natural Selection on Host‐Parasite Phenotypes
It is demonstrated that preening with a normal bill selects for small body size in lice, which may facilitate their escape from preening, which is a crucial element of coevolutionary theory.
Relationship of host coloniality to the population ecology of avian lice (Insecta: Phthiraptera)
Rooks harboured more species-rich louse loads than crows and sex ratios of lice were less biased on rooks than on crows, which may result from the increased frequency of horizontal transmissions via increased body-to-body contacts among colonial rooks, compared to territorial hooded crows.

Compared the virulence of lice and mites infesting a single group of captive rock doves, results support the hypothesis that ectoparasite virulence is linked to the mode of transmission.
Ectoparasites reduce long-term survival of their avian host
It is suggested that future studies of ectoparasitism should consider the parasites’ effect on annual survival of adult hosts and suggest that all birds in the population were at potential risk of suffering parasitism and the resulting reductions in survivorship.

Seasonal Changes in Immune Response and Parasite Impact on Hosts
It is suggested that hole nesters suffer greater reduction in breeding success because of virulent parasites than do open nesters, and this seasonal change in immune function is suggested to have arisen as a response to the increased virulence of parasites attacking hole‐nesting birds.
