Understanding host-parasite interactions requires that the multi-faceted relationships among
ecological, behavioral and molecular processes be characterized and integrated. The …

The muscid genus Philornis comprises approximately 50 described species of flies, nearly
all of which are obligate parasites of nestling birds. Philornis species are native to the …

40 Years of Evolution is a landmark study of the finches first made famous by Charles
Darwin, one that documents as never before the evolution of species through natural …

Species hybridization can lead to fitness costs, species collapse, and novel evolutionary
trajectories in changing environments. Hybridization is predicted to be more common when …

Invasive species remain one of the greatest threats to global biodiversity. Their control would
be enhanced through the development of more effective and sustainable pest management …

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 …

This chapter discusses the invasion of an avian nest fly, Philornis downsi, to the Galapagos
Islands, its interactions with novel bird hosts, and the strategies that are being implemented …

Host‐associated microbiota can be affected by factors related to environmental change,
such as urbanization and invasive species. For example, urban areas often affect food …

Background Introduced parasites are a particular threat to small populations of hosts living
on islands because extinction can occur before hosts have a chance to evolve effective …

The declining-population paradigm holds that small populations are particularly vulnerable
to anthropogenic influences such as habitat destruction, pollution and species introductions …
