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 ... -
Single cell analysis of tail regeneration in Ambystoma mexicanum
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)This present study examined tail regeneration in the Mexican salamander Ambystoma mexicanum, on a single cell level in vivo. The primary aim of this study was to understand where the cells were coming from to replace all ... -
The impact of neuronal activity manipulations on recovery after complete spinal transection in the Eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Spinal cord injury is a tragically debilitating event affecting up to 5 or more out of every 100,000 people in many countries across the globe. Axotomised neurons in the mammalian CNS are unfortunately unable to regenerate ... -
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 ... -
The water quality requirements of white-clawed crayfish, Austropotamobius pallipes Lereboullet (1858) in Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)Despite the decreasing water quality and the occurrence of the crayfish plague, the unique conditions present in Ireland offer a good opportunity to study aspects of the ecology of the white-clawed crayfish. Ireland is now ... -
Morphological change in nucleus accumbens neurons as a basis for the development of haloperidol-induced movement disorders
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)A syndrome of involuntary, hyperkinetic abnormal movements called tardive dyskinesia (TD) develop in predisposed individuals following treatment and withdrawal from neuroleptic drugs. These movements are primarily orofacial ... -
The ecology of the family Chydoridae (Branchiopoda, Anomopoda) and its application to lake monitoring
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)Chydorids (Branchipoda, Anomopoda) were sampled from twenty nine Irish lakes between June 1996 and July 1997, in order to assess the usefulness of this group as indicators of lake ecological quality. The lakes represented ... -
The parasite community structure of stocked and wild brown trout (Salmo trutta L.)
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The present study examined the parasite component and infracommunities of wild and stocked brown trout from an experimental fishery, Lough Feeagh and compared them to the parasite component and infracommunities of wild ... -

The influence of multimodal warning displays on avian avoidance behaviour
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)This thesis empirically investigates the effects of insect multimodal warning displays on avian predatory decisions. Specifically, it examines the effects of pyrazine odour, and the agitated buzzing of a bumble bee on ... -
The impact of Nosema bombi on its bumble bee hosts : ecology, epidemiology and the wider context of multiple parasitism
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Bumble bees are eusocial insects that play a key role in ecosystem function as essential pollinators for many flowering plants (Alford, 1975). The importance of their diseases, for example damage caused by the microsporidian ... -
Ecology, epidemiology and evolution in a gut trypanosomatid parasite of bumble bees with multiple host species
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)I have empirically explored the impact of different factors on the coevolution of a multihost-parasite system consisting of a gut trypanosomatid and its bumble bee host species assemblage. I have studied the potential ... -
Neurotrophin mRNA expression in the central nervous system of the brain stem-spinal cord regenerating model, Anguilla anguilla, the European eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)Neuronal regeneration is extremely limited in the central nervous system (CNS) of mature amniotes. On the other hand, many anamniotes, such as some fish, display rapid morphological and functional recovery after CNS injury, ... -
Eutrophication and phytoplankton in the Liffey Estuary and Dublin Bay
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Temperature, salinity, nutrient and chlorophyll concentrations, and Secchi depth were measured monthly at 41 stations in the Liffey estuary and Dublin Bay from June 2000 to June 2004. Analysis of nutrient composition and ... -
Susceptibility and mortality in honeybees (Apis mellifera) infested with the tracheal mite (Acarapis woodi)
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)The tracheal mite, Acarapis woodi (Rennie), is an obligate parasite of the honeybee. It was first discovered in 1919 by Rennie during his investigation into the widespread deaths of honeybee colonies in Europe in the early ... -
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 ... -
The development of a mouse model to explore resistance and susceptibility to early Ascaris suum infection
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Ascaris suum and Ascaris lumbricoides are widespread geohelminths of pigs and humans, respectively, resulting in severe morbidity and possible mortality. The contribution of migrating A. suum larvae to liver damage has ... -
Granivorous passerines across an agricultural gradient in winter : from habitat use to community structure
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)In recent decades, agricultural intensification has had profound adverse effects on farmland biodiversity, especially within the more industrialised regions of Westem Europe. Among the most severely affected groups have ... -
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 ... -
Modelling the impact of two intertidal primary consumer mollusc species on microphytobenthic biomass
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)As many marine intertidal benthic primary consumers are relatively small in body size, their individual impact on the environment is generally negligible. The combined influence of the extremely high numbers of individuals ...
