A genetic and morphological investigation of the forces shaping the diversity and distribution of the Eurasian red squirrel, Sciurus vulgaris
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)An understanding of the factors which shape the range of, and distribution of diversity within, a species, is fundamental in understanding both the species itself, but also, the effectiveness, if needed, of conservation ... -
A light and electron microscopical study of the regenerating spinal cord of the Eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The present study examined the regenerative capability o f the European eel Anguill anguilla following spinal cord transection injury using both light and electron microscopy. The primary aim of this investigation was to ... -
A murine model for celebral toxocariasis : characterisation of susceptibility, behaviour and immune response
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Toxocara canis, the parasitic roundworm of dogs, can infect a number of paratenic hosts, such as mice and humans, due to the widespread dissemination of its ova in the environment (Glickman and Schantz, 1981). In the murine ... -
A study on the endocrine disrupting effect of estrogenic compounds on the zebra mussel, (Dreissena polymorpha) : an in vivo/in vitro approach
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Endocrine disruption (ED) by environmental estrogens has become a major research area in environmental toxicology after the discovery that chemicals entering the environment had a feminising effect on exposed male animals. ... -
Addressing fundamental behavioural and welfare issues associated with zoo housed animals : using lowland tapirs Tapirus terrestrius and giraffes Giraffa camelopardalis as model species
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Introduction: Zoos, living museums and menageries have been around since early Egyptian and Roman times. Throughout the ages zoos have developed a more important role than merely exhibits. Nowadays, zoos serve a major role ... -
An integrated assessment of estrogenic endocrine disruption in the Irish marine envrionment, with particular emphasis on chemical measurements
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)Scientific awareness of the presence and effects of endocrine disrupting compounds (EDCs) has increased in recent decades. Many gaps in the knowledge still exist, particularly in relation to concentrations and potential ... -
An investigation into the ecology of the pine marten (Martes martes) in Killarney National Park
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)The majority of the research for this thesis was carried out on a reestablished population of pine marten in Killarney National Park (KNP). I explored the success of the translocation and used distributional, biometric and ... -
An investigation into the short-term effects of environmental enrichment on the behaviour of psittacines in captivity
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)There is a lack of quantitative information available about the effects of environmental enrichment on avian orders, compared with the amount of similar research carried out on mammals. This is particularly surprising where ... -
An investigation of strain differences in Pomphorhynchus laevis (acanthocephala) : an ecological, morphological and molecular approach
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)Kennedy, Bates and Brown (1989) stated that in the British Isles the acanthocephalan, Pomphorhynchus laevis could be separated into three strains, an English, Irish and marine strain. Much ecological evidence exists in ... -
Applying quantitative methods to conservation planning : Population dynamics of the Eurasian otter in Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)As appears typical in the field of conservation biology, the current study has parallel aims. The first is to improve both the limited toolbox and the biological information available for the conservation of a vulnerable ... -
Assessing novel cultivation methods, baseline fish assemblages and survey methodologies of cultivated and wild kelp in the Southwest of Ireland
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)Kelp (i.e. large brown macroalgae of the order Laminariales) are important habitat-forming species in coastal ecosystems. Recently, the key role kelp play as part of an expanding blue economy has been recognised in addition ... -
Assessment of scallop (Pecten maximus) stocks in the Irish and Celtic seas
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Spatially explicit approaches (differing from the traditional stock assessment theory) to the assessment of scallop off the southeast coast of Ireland were developed. Different stock assessments methods were presented with ... -
Avian speciation and biodiversity in South-east Sulawesi, Indonesia: drivers of diversification
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)As biodiversity loss reaches critical levels, greater knowledge of its distribution is needed to concentrate conservation efforts. Biodiversity can be measured at several levels, with the species typically the unit used ... -
Benthic habitat mapping in the southern Irish Sea
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Habitat mapping is an extremely important area in marine science. Before we can conserve areas or consider the potential impacts of industries such as fishing, aggregates, windfarms and wave or tidal turbines, we first ... -
The biology and ecology of regionally endothermic fishes in Irish waters
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)The waters surrounding Ireland are very productive due to cold water upwellings. This has led to Irish waters supporting many livelihoods such as those in tourism and fisheries, with some specialising in catching and ... -
Changing social groups in zoo populations
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)Changes in social groups of animals in zoos occur frequently, and group structures can be changed in a variety of ways: introductions of animals, removals of animals, births and deaths. Information on procedures used to ... -
Collagen Deposition, Cellular and Molecular characterisation of self-assembled tendon constructs grown in vitro from embryonic chick tenocyte cells
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2025)Tendons are fibrous connective tissues that connect and transmit forces between muscle and bone. Following injury, they are very difficult to repair surgically, often resulting in tissue that is not comparable to native ... -
Community structure and recruitment of decapods in shallow sub-littoral habitats
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)Although decapod crustaceans represent a major component of benthic fauna in many geographic localities around the world, little is known of their early benthic life history. This study examined the relative influences ... -
Defining disturbance in time : the ecological implications of varying temporal patterns of disturbances
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Prediction and mitigation of the effects of global environmental change rely primarily on our capacity to anticipate its causes and consequences. Key to this is the ability to identify and understand the mechanisms that ... -
Dietary conservatism in passerines : the influence of novel odour and novel colour
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)This research was concerned with the way that passerine bird species use odour cues in isolation and in combination with colour cues to make decisions about new foods. Galliformes are known to demonstrate a disproportionately ...
