Optimális vedlési stratégiák = Optimal moult strategies [PDF]

open access: yes, 2009
A pályázat fő célja annak kiderítése volt, hogy a különböző állapotváltozók hogyan befolyásolják az optimális viselkedést, speciálisan a hogyan befolyásolják a fő életmenet események időzítését az éves cikluson belül. E cél elérése érdekében több modellt

Assessing the Consequences of Brood Parasitism and Nest Predation On Seasonal Fecundity in Passerine Birds [PDF]

open access: yes, 1995
Brood parasites and nest predators reduce the seasonal fecundity and, hence, the population growth rates of their victims. However, most field studies do not measure directly how parasites and predators decrease seasonal fecundity, but instead measure ...

High fidelity: extra-pair fertilisations in eight Charadrius plover species are not associated with parental relatedness or social mating system [PDF]

open access: yes, 2017
Extra-pair paternity is a common reproductive strategy in many bird species. However, it remains unclear why extra-pair paternity occurs and why it varies among species and populations.

Can nest design hinder brood parasitism success?

open access: yesJournal of Avian Biology
Avian nest design varies depending on environmental factors but may also be influenced by between‐species interactions. In the brood parasitism context, hosts may evolve nest architectures that may limit parasite access to the nest cup, reduce parasite ...

Early-life adversity accelerates cellular ageing and affects adult inflammation: experimental evidence from the European starling [PDF]

open access: yes, 2017
Early-life adversity is associated with accelerated cellular ageing during development and increased inflammation during adulthood. However, human studies can only establish correlation, not causation, and existing experimental animal approaches alter ...

A general framework for modeling pathogen transmission in co‐roosting host communities

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract Cross‐species transmission of pathogens can be facilitated by frequent contact among wildlife. Cross‐species transmission is often driven by phylogenetic similarity between host species, but the role this plays when multiple host species co‐roost is unknown.

Nestling diet, secondary sexual traits and fitness in the zebra finch [PDF]

open access: yes, 1999
We examined the effect of nestling diet quality on a suite of physiological, morphological and life-history traits in adult male zebra finches,Taeniopygia guttata.

Avian extra‐pair paternity in the last European primeval forest

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 338-346, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Primeval forests offer a reference baseline to understand the origins and evolution of mating systems, as their relatively undisturbed environment provides a glimpse into how ecological interactions and natural selection play out in their original context.

The Evolution of Clutch Size in Hosts of Avian Brood Parasites [PDF]

open access: yesThe American Naturalist, 2017
Coevolution with avian brood parasites shapes a range of traits in their hosts, including morphology, behavior, and breeding systems. Here we explore whether brood parasitism is also associated with the evolution of host clutch size. Several studies have proposed that hosts of highly virulent parasites could decrease the costs of parasitism by evolving
