Nesting Success and Nesting Height in the Critically Endangered Medium Tree Finch (Camarhynchus pauper)

Birds, 2021
When different introduced species across trophic levels (parasite, predator) invade island systems, they may pose significant threats to nesting birds.

Behavioural response to songs between genetically diverged allopatric populations of Darwin’s small tree finch in the Galápagos

Journal of Evolutionary Biology, Volume 34, Issue 5, Page 816-829, May 2021., 2021
Male song can signal species identity and male quality, and behavioural response to song can drive divergence or introgression. In this study, we describe clear differences in male song types and a weak signal of population genetic difference across two populations of small tree finch on two Galapagos Islands. Resident males responded to the song of an

Introduced parasite changes host phenotype, mating signal and hybridization risk: Philornis downsi effects on Darwin's finch song. [PDF]

Proc Biol Sci, 2019
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 threatened by the introduced fly Philornis downsi that is thought to have ...

Sequence alignment data for trypanosomatidae parasites found in Philornis downsi from the Galapagos Islands

, 2020
Sequences of parasites in Philornis downsi, an invasive parasitic Dipteran species, were obtained via PCR tests targeting the 18S rRNA gene of the Trypanosomatidae family.

Personality in the parasitic avian vampire fly (Philornis downsi)

Behaviour
Abstract Personality, i.e., consistent and repeatable differences in behaviour between individuals, has been documented and studied across taxa. However, relatively little research attention has been given to personality in invertebrates, particularly in parasitic species. The avian vampire fly

The birds and the trees: Avian ecosystem (dis)service perspectives and farmers' willingness to plant native trees in the agricultural landscape of the Galapagos Islands

People and Nature, Volume 7, Issue 12, Page 3182-3206, December 2025.
Abstract Agricultural landscapes hold great potential for biodiversity conservation; however, this will require finding solutions that work for both people and nature. Increasingly, the conservation community is calling for more cross‐disciplinary research integrating ecological questions with social and behavioural sciences for a more complete and ...

Avian vampire fly (Philornis downsi) intensity and mortality

, 2021
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 parasites towards specialism to avoid costly hosts.

Competition among invasive and endemic carrion fly species in the Galapagos Islands with implications for biological control risk assessment

Insect Conservation and Diversity, Volume 17, Issue 3, Page 409-418, May 2024.
Introduced fly dominance: The Galapagos necrobiome is dominated by introduced carrion flies, with Peckia chrysostoma as the most abundant species, outcompeting native and endemic species. Endemic fly vulnerability: Endemic and native carrion flies, like Sarothromyiops dasycnemis, face competition and potential displacement by introduced species ...
