Parental care in the Small Tree Finch Camarhynchus parvulus in relation to parasitism and environmental factors. [PDF]
The parental food compensation hypothesis suggests that parents may compensate for the negative effects of parasites on chicks by increased food provisioning. However, this ability differs widely among host species and may also depend on ecological factors such as adverse weather conditions and habitat quality.

Genomic Insights into the Successful Invasion of the Avian Vampire Fly (Philornis downsi ) in the Galápagos Islands. [PDF]
Abstract Invasive species pose significant threats to island ecosystems, often leading to the decline of native species and the disruption of ecological balance. The avian vampire fly (Philornis downsi), introduced to the Galápagos Islands of Ecuador, has emerged as a major threat to the endemic avifauna, parasitizing multiple species

Kinship Analysis Confirms Tolerant Galapagos Mockingbirds Are a Source of Nest Flies That Threaten Darwin's Finches. [PDF]
ABSTRACT Host species have evolved different strategies for dealing with parasites. ‘Vulnerable’ hosts, which suffer reduced fitness from parasites, are under selection to evolve defences. ‘Tolerant’ hosts, by contrast, avoid reductions in fitness by mitigating parasite damage.

Under adverse conditions, older small tree finch males (Camarhynchus parvulus) produce more offspring than younger males. [PDF]
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 ...

Using modified trapping regimes to understand the behavioral and spatial ecology of Philornis downsi (Diptera: Muscidae). [PDF]
Abstract The avian vampire fly Philornis downsi (Dodge & Aitken) (Diptera: Muscidae) is native to continental South America and the Caribbean, but invasive in the Galapagos Archipelago. The larvae of P. downsi feed on the blood and tissues of the nestlings of 75% of the small land bird species that are endemic or native to Galapagos,

Urban living influences the nesting success of Darwin's finches in the Galápagos Islands. [PDF]
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]
ABSTRACT 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.

Economic costs of biological invasions in Ecuador: the importance of the Galapagos Islands [PDF]
Biological invasions, as a result of human intervention through trade and mobility, are the second biggest cause of biodiversity loss. The impacts of invasive alien species (IAS) on the environment are well known, however, economic impacts are poorly ...
