Urban environmental pollution results in contamination of the tissues of synanthropic
organisms by toxic trace elements with potential impacts on human health. Passerine birds …

Abstract Theory suggests that overcrowding and increased competition in urban
environments might be detrimental to individual condition in avian populations …

Parasites play a key role in regulating wildlife population dynamics, but their impact on the
host appears to be context-dependent. Evidence indicates that a synergistic interaction …

Species-specific neural inflammation can be induced by profound immune signalling from
periphery to brain. Recent advances in transcriptomics offer cost-effective approaches to …

Haemosporidians causing avian malaria are very common parasites among bird species.
Their negative effects have been repeatedly reported in terms of deterioration in survival …

In response to population declines in several bird species, knowledge of habitat quality
provides essential information to optimise conservation and management plans …

The degree to which avian haemosporidian parasites can exploit different vectors as a
definitive host has ecological implications for their transmission and biogeography. Studies …

Researchers interested in ecological immunology face substantial methodological
problems: 1) most immunological approaches are difficult to perform in free‐living animals …

Little is known of how the stress response varies when animals confront seasonal life-history
processes. Antioxidant defenses and damage caused by oxidative stress and their link with …
