Galápagos mockingbirds tolerate introduced parasites that affect Darwin's finches.
Introduced parasites threaten native host species that lack effective defenses. Such parasites increase the risk of extinction, particularly in small host populations like those on islands. If some host species are tolerant to introduced parasites, this could amplify the risk of the parasite to vulnerable host species. Recently, the introduced parasitic nest fly Philornis downsi has been implic...
متن کاملIncreasing awareness of avian ecological function.
Birds are one of the most diverse groups of ecosystem service providers, whose ecological functions range from creating soil to shaping primate behavior, Nevertheless, the impression that birds have little influence on ecological processes has been hard to change. Given the ongoing declines in avian functional groups, there is a pressing need to compare avian ecological functions to those of ot...
متن کاملImmune function varies with reproductive stage and context in female and male tree lizards, Urosaurus ornatus.
Competition among physiological processes for limited resources often results in trade-offs. Key among these processes is reproduction and immune function, and optimizing both appears to be difficult. To test the hypothesis that the resource demands of reproduction compromise immune function, we measured rates of wound healing, an integrated measure of innate immunity, across different reproduc...
متن کاملEmergence of a Novel Avian Pox Disease in British Tit Species
Avian pox is a viral disease with a wide host range. In Great Britain, avian pox in birds of the Paridae family was first diagnosed in a great tit (Parus major) from south-east England in 2006. An increasing number of avian pox incidents in Paridae have been reported each year since, indicative of an emergent infection. Here, we utilise a database of opportunistic reports of garden bird mortali...
متن کاملA century of genetic change and metapopulation dynamics in the Galápagos warbler finches (Certhidea).
Populations that are connected by immigrants play an important role in evolutionary and conservation biology, yet we have little direct evidence of how such metapopulations change genetically over evolutionary time. We compared historic (1894-1906) to modern (1988-2006) genetic variation in 11 populations of warbler finches at 14 microsatellite loci. Although several lines of evidence suggest t...
