Genetic admixture predicts parasite intensity: evidence for increased hybrid performance in Darwin's tree finches [PDF]
Royal Society Open Science, 2019 Hybridization can increase adaptive potential when enhanced genetic diversity or novel genetic combinations confer a fitness advantage, such as in the evolution of anti-parasitic mechanisms. Island systems are especially susceptible to invasive parasites

Under adverse conditions, older small tree finch males (Camarhynchus parvulus) produce more offspring than younger males. [PDF]
Ethology, 2020 In many bird species, females paired with older males have a higher breeding success. Small tree finches are heavily affected by an invasive nest parasite. Nests of older males had more fledglings than those of younger males. However, the difference in breeding success disappeared when parasites were experimentally reduced with the insecticide ...

Urban living influences the nesting success of Darwin's finches in the Galápagos Islands. [PDF]
Ecol Evol, 2021 Urbanization is expanding worldwide with major consequences for organisms, understanding the trade‐offs of urbanization is of critical importance, particularly in environments with unreliable annual natural food availability, such as the Galápagos Islands.

Genomic Introgression Between Critically Endangered and Stable Species of Darwin's Tree Finches on the Galapagos Islands. [PDF]
Evol ApplABSTRACT Natural hybridisation among rare or endangered species and stable congenerics is increasingly topical for the conservation of species‐level diversity under anthropogenic impacts. Evidence for beneficial genes being introgressed into or selected for in hybrids raises concurrent questions about its evolutionary significance.

Global Ecology and Conservation, 2016 The rate of evolution depends on the strength of selection, which may be particularly strong for introduced parasites and their naive hosts. Because natural selection acts on phenotypes and because parasites can alter host phenotype, one fruitful ...

From dispenser to nest: collection of fumigated material repels parasites across behavioural traits in Darwin’s finches [PDF]
BMC ZoologyIn the midst of a biodiversity crisis, it is important to conserve diversity at all levels, including species, genetic, and behavioural diversity. Animals with different behavioural traits can interact with their environment in distinct ways; hence, the ...
