The nesting behaviour of laying hens in large furnished cages
… laying hens to perform highly motivated behaviour patterns, especially nesting. Incontrast, furnished cages positively impact the welfare of hens by providing necessaryresources, like nest areas. However, the current requirements for a nest, stipulated withincurrent guidelines and welfare …

Dedicated dads: a study on the nesting behaviour of Spondyliosoma emarginatum (Telostei: Sparidae)
Fish display the most diverse parental care behaviours within the animal kingdom. These behaviours are important from evolutionary and conservation perspectives as parental care is critical for the development and survival of the young. This study used video monitoring to uncover the nesting …

Lizdavietėse-gaudyklėse apsigyvenančių klosčiavapsvių (Hymenoptera: Vespidae: Eumeninae) vystymasis ir rūpinimosi palikuonimis elgsena /
… purpose of our study was to establish impact of nesting cavity parameters and prey abundance on the nesting behaviour of solitary xylicolous wasps. We studied nest structure and the influence of nesting cavity width and length on progeny size and sex ratio in 13 wasp species. The development of …

Conflict & Communication: Consequences Of Female Nest Confinement In Yellow-Billed Hornbills
… of hornbills (Bucerotiformes) is their unusual nesting behaviour. Before laying, a female hornbill enters the nest in a tree cavity. Uniquely among birds, she then seals the nest entrance using her faeces and locally available materials, leaving a narrow gap only 1 cm wide. Through this tiny …

Estudos comparados sobre morfologia de imaturos e comportamento de Sphecinae (Insecta: Hymenoptera: Sphecidae)
… world. This group is very diverse and complex behaviourally. The objective of the present work is comparatively studying the immature morphology and the nesting behaviour of species of Sphecinae, in a way to contribute to the understanding of the phylogeny of the group and discussing about …

The effects of dung beetles on ecosystem functioning: From global trends to New Zealand pastures
Dung beetles are amazing. Their diverse nesting behaviours affect a suite of important biotic and abiotic ecosystem processes, or functions. However, the dynamics of these functions across different ecosystems and over time remain largely unknown. This PhD thesis investigates the relationships …

Neuroendocrine regulation of broodiness in the domestic hen
… and subsequent care of the young. Incubation behaviour is initiated by increased plasma progesterone and oestrogen from maturing ovarian follicles that induce nesting behaviour. This is subsequently transformed into incubation behaviour by increased plasma prolactin in association with …

Honey bee behavioural evolution and itpr gene structure studies
… in order to determine food recruitment and nesting behaviour ancestral traits in Apis. In my first experiment, I focused on foraging behaviour performed by the forager honey bee. Its ability to conduct food recruitment through elegant dance behaviour is facilitated by memory formation in the …
