Ghrelin, Cannabinoids, and Motivation: Increased Food Motivation on Progressive Ratio Paradigm Through MAGL/FAAH Inhibition in a Rat Model
… in the ventral tegmental area (VTA) to increase feeding behaviours, through their interaction is not understood. It is hypothesized that ghrelin influences this system by stimulating the release of endocannabinoids from dopamine cells through its receptor, via increased synthesis and accumulation …

Understanding the Mechanisms that Determine Feed Conversion Ratio in Chinook Salmon – Physiological and Behavioural Aspects
… phenotypes when fed a set ration. To assess feeding behaviour a novel application of the ballotini method was developed to determine the timing of feeding in fish. Two bead sizes (dual ballotini) were fed in different halves of the meal to assess when fish ate. No difference was found when …

Interactions Between Ants and Larvae of the Host- Manipulating Parasite, Dicrocoelium Dendriticum
… that regulate the action of the mandibles, feeding behaviours, and temperature sensing. My results provide the key foundation for further studies designed to determine whether the complex manipulation of ant behaviour requires direct physical and/or neurochemical modulation by the brain worm.

Analysis of the feeding behaviour of the mosquito Culex pipiens L. (Diptera: Culicidae) in relation to West Nile virus
… review describe the life cycle and blood feeding behaviours ofmosquitoes so that baseline data ofmosquito biology are established. In addition to explaining how and why a mosquito blood feeds, the section on "Blood Meal Analysis" describes the different methods for determining the …

Food Resource Utilization By Five Species Of Benthic Feeding Fish In Passamaquoddy Bay, New Brunswick
Feeding relationships of various fish species, and their relationship to the composition of the surrounding sediments, were observed for one year at two sites in the lower Bay of Fundy region. The fishes were the ocean pout (Macrozoarces americanus), winter flounder (Pseudopleuronectes americanus), …

How rewilding impacts ecosystem health in a semi-arid region
… beetle assemblages via megafauna trampling and feeding behaviours, ultimately improving ecosystem health. This was conducted in two different vegetation types, Montagu Shale Renosterveld and Western Klein Karoo. By examining these key indicators of ecosystem health, this research has revealed …

Exploring parental attitudes and practices during complementary feeding
… to access information on complementary feeding (also referred to as weaning) through the health services. Parental adherence to the weaning guidelines however, has been assessed to be unsatisfactory on a national level. A big challenge therefore for researchers working in the field of …

Neuromolecular basis of anomalous feeding behaviour in the valproate rat model of autism
… disability, sensory anomalies, repetitive behaviours, and intellectual disability. Aberrant feeding behaviour is a common comorbidity of ASD. ASD individuals often demonstrate extreme food selectivity, refusal, dependence on few very particular food items, neophobia etc. which can lead to …

Trophic role of small cetaceans and seals in Irish waters
… occasionally forage on the continental shelf, feeding on available prey. The Atlantic white-sided dolphin diet showed that this species prefers to feed over the continental edge, where planktivorous fish are abundant. Some resource partitioning was found in bottlenose dolphins in Irish waters …

The use of infrared thermography and behavioural and physiological responses as early disease indicators in calves
… to firstly, investigate the behavioural (milk feeding, lying and water drinking) and physiological (infrared temperatures and respiration rate) responses which occur during the onset of neonatal calf diarrhoea (NCD), and to assess their suitability as early disease indicators. Additionally, due …

A neural and behavioural investigation of aberrant feeding in animal models of autism spectrum disorder
… over 60% of ASD individuals. Data suggest that feeding abnormalities include heightened food selectivity, neophobia and food refusal, as well as pica (consumption of non-food items). The current knowledge of the scope and magnitude of abnormal appetite in ASD as well as neuropathology underlying …

Behavioural ecology of the black-flanked rock-wallaby (Petrogale lateralis lateralis): Refuge importance in a variable environment
… information on their behavioural, foraging and feeding patterns, and how these affect the population dynamics of the species. Although this species appears to be substrate bound, requiring complex rock structures that are believed to protect them from both predators and adverse climatic …

Herbivorous fishes as determinants of the structure of coral reef communities: farmers, foragers and their interactions
… assessed. Two groups of fish with very different feeding behaviours and potential impacts on benthic communities are the territorial herbivores, (primarily damselfish; termed ‘farmers’ throughout this thesis), and the more mobile, often schooling herbivores, (primarily parrotfish and surgeonfish; …
