Infection by a helminth parasite is associated with changes in DNA methylation in the house sparrow
Ecology and Evolution, 2022 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 resistance, the role of epigenetics in the immune response to parasites is less

Plasma metabolites reflect seasonally changing metabolic processes in a long-distance migrant shorebird (Calidris canutus) [PDF]
, 2002 Migrant birds have tightly scheduled annual cycles consisting of several distinct life cycle (sub-)stages such as reproduction, migration, moult and overwintering, each of which have specific metabolic requirements (e.g., fattening during migration ...

Neotropical Bird Migration During The Ice Ages: Orientation And Ecology [PDF]
, 1996 Reconstruction of breeding habitat of North American Neotropical migrants 18,000 years ago and 9,000 years ago indicated major shifts in both location and composition of plant communities relative to present conditions.

Effect of timing and female quality on clutch size in the Collared Flycatcher Ficedula albicollis [PDF]
, 2004 Capsule: Laying date and female age appear to be related to clutch size. Aims: To test two hypotheses ('date' and 'quality'), which might explain why fewer eggs are laid late in the season.

Long-distance dispersal patterns in the Cerulean Warbler: a case study from Indiana
Avian Conservation and Ecology, 2023 Dispersal, defined as movement an individual makes from one breeding population to another, is a process that strongly influences the population dynamics of many animal species.

The role of UV in crab spider signals: effects on perception by prey and predators [PDF]
, 2005 Australian crab spiders Thomisus spectabilis sit on the petals of flowers and ambush prey such as honeybees. White-coloured T. spectabilis reflect in the UV (UV+ spiders) and previous research has shown that their presence, curiously, attracts honeybees ...

Genetic and phenotypic divergence in an island bird: isolation by distance, by colonization or by adaptation? [PDF]
, 2014 Discerning the relative roles of adaptive and nonadaptive processes in generating differences among populations and species, as well as how these processes interact, is a fundamental aim in biology.
