Domestic animals have immense economic, cultural, and practical value and have played
pivotal roles in the development of human civilization. Many domesticates have, among their …

Selection should act on parental care and favour parental investment decisions that optimize
the number of offspring produced. Such predictions have been robustly tested in predation …

The parasitic larvae of Philornis downsi Dodge & Aitken (Diptera: Muscidae) were first
discovered in Darwin's finch nests on the Galápagos Islands in 1997. Larvae of P. downsi …

Introduced parasites that alter their host's mating signal can change the evolutionary
trajectory of a species through sexual selection. Darwin's Camarhynchus finches are …

Darwin's finch species in the Galapagos Archipelago are an iconic adaptive radiation that
offer a natural experiment to test for the various factors that influence gut microbiome …

Although parasite-mediated selection is a major driver of host evolution, its influence on
genetic variation for parasite resistance is not yet well understood. We monitored resistance …

In invasive parasites, generalism is considered advantageous during the initial phase of
introduction. Thereafter, fitness costs to parasites, such as host-specific mortality, can drive …

Hybridization in natural populations may be an adaptive response to shifting climatic
regimes, but understanding this can be limited by the timing of sampling effort and confident …

The avian beak is a key morphological trait used for foraging. If parasites alter beak shape,
we may expect changes in host foraging behaviour. Larvae of the avian vampire fly Philornis …

Although in-nest parasitism can reduce the fitness of avian hosts, the severity of these effects
may vary with host physiology and behaviour. If certain nestling behaviours are beneficial for …
