Mountain ecosystems are inhabited by highly specialised and endemic species which are
particularly susceptible to climatic changes. However, the mechanisms by which climate …

Simple Summary In the present review, information about parasitic helminths
(Platyhelminthes, Nematoda, and Acanthocephala) of wild birds in Ecuador is presented …

Parasites can exert strong selective pressures on their hosts and influence the evolution of
host immunity. While several studies have examined the genetic basis for parasite …

Investigating factors which affect the decline in survival with age, ie actuarial senescence, is
important in order to understand how demographic rates vary in wild populations. Although …

Anthropogenic pollution is identified as an important threat to bird and other wildlife
populations. Many metals and toxic elements, along with poly-and perfluoroalkyl substances …

The house sparrow (Passer domesticus) is a small passerine known to be highly sedentary.
Throughout a 30‐year capture–mark–recapture study, we have obtained occasional reports …

Parasites have the potential to severely reduce host reproductive success. However, the
effects of endoparasites on reproductive success have not received the same amount of …

Host–parasite relationships are likely to change over the coming decades in response to
climate change and increased anthropogenic stressors. Understanding the genetic …

A deceased ring-necked pheasant (Phasianus colchicus) presented for necropsy following a
history of chronic wasting. Necropsy revealed nematodes consistent with the genus …

Individual reproductive success largely depends on the ability to optimize behaviour,
immune function and the physiological stress response. We have investigated correlations …
