High functional allelic diversity and copy number in both MHC classes in the common buzzard

open access: yesBMC Ecology and Evolution, 2023
Background The major histocompatibility complex (MHC), which encodes molecules that recognize various pathogens and parasites and initiates the adaptive immune response in vertebrates, is renowned for its exceptional polymorphism and is a model of ...

Plumage and Fat Condition Scores as Well-Being Assessment Indicators in a Small Passerine Bird, the Zebra Finch (Taeniopygia guttata)

open access: yesFrontiers in Veterinary Science, 2022
The well-being of animals kept by humans in laboratories, farms, or as pets should always be of the highest importance, and a prerequisite for this is adequate housing.

Implications of nutritional stress as nestling or fledgling on subsequent attractiveness and fecundity in zebra finches (Taeniopygia guttata) [PDF]

open access: yesPeerJ, 2017
The conditions an organism experiences during early development can have profound and long lasting effects on its subsequent behavior, attractiveness, and life history decisions.

Machine learning prediction of sleep stages in dairy cows from heart rate and muscle activity measures

open access: yesScientific Reports, 2021
Sleep is important for cow health and shows promise as a tool for assessing welfare, but methods to accurately distinguish between important sleep stages are difficult and impractical to use with cattle in typical farm environments. The objective of this

A guide to sampling design for GPS‐based studies of animal societies

open access: yesMethods in Ecology and Evolution, 2023
GPS‐based tracking is widely used for studying wild social animals. Much like traditional observational methods, using GPS devices requires making a number of decisions about sampling that can affect the robustness of a study's conclusions.

The relationship between social rank and spatial learning in pheasants, Phasianus colchicus: cause or consequence? [PDF]

open access: yesPeerJ, 2018
Individual differences in performances on cognitive tasks have been found to differ according to social rank across multiple species. However, it is not clear whether an individual’s cognitive performance is flexible and the result of their current ...

Integrating Behavioural Animation Techniques [PDF]

open access: yesComputer Graphics Forum, 2001
Our research focuses on animating autonomous virtual humans which are able to take decisions by themselves. We especially address in this paper the technical problem of integrating altogether the physical simulation of agents (represented as virtual humans in a 3D environment) and their behaviours and motivations, driven by a Beliefs, Desires and ...

Size dimorphism and sexual segregation in pheasants: tests of three competing hypotheses [PDF]

open access: yesPeerJ, 2018
Fine scale sexual segregation outside of the mating season is common in sexually dimorphic and polygamous species, particularly in ungulates. A number of hypotheses predict sexual segregation but these are often contradictory with no agreement as to a ...

Clever strategists: Australian Magpies vary mobbing strategies, not intensity, relative to different species of predator [PDF]

open access: yesPeerJ, 2013
Anti-predator behaviour of magpies was investigated, using five species of model predators, at times of raising offspring. We predicted differences in mobbing strategies for each predator presented and also that raising juveniles would affect intensity ...

Olfactory sex preferences in six Estrildid Finch species

open access: yesFrontiers in Ecology and Evolution, 2023
Avian courtship behaviour is essential to attract potential mating partners. Courtship behaviours can involve displays of different sensory modes. Sex discrimination is a crucial step and in many bird species, sexes differ in acoustic and visual traits ...
