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 ... -
Systematics of Eriocaulaceae in Thailand
(Trinity College (Dublin, Ireland). Department of Botany, 2006)This thesis aimed to provide a complete account of the family Eriocaulaceae for Thailand, to resolve the identity of unknown Thai taxa in the family and to investigate the relationship between Thai species using morphological, ... -
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 ... -
Evidence of former tree growth at Clonsast
(Trinity College (Dublin, Ireland), 1957)Six thousand years ago practically all the ground now covered by peat in the area investigated at Clonsast, County Offaly, was woodland. The main object of the research was to trace the disappearance of woodland due to ... -
The origin and evolutionary history of the turlough form of Ranunculus repens
(Trinity College (Dublin, Ireland). Department of Botany, 2004)Turloughs are temporary lakes that occur in karstic limestone areas predominantly in the West of Ireland. They generally flood with groundwater in Autumn and empty through swallow holes in late Spring. This strong ecological ... -
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 ... -
The characterisation of genetic diversity of a collection of perennial ryegrass (Lolium perenne L.)
(Trinity College (Dublin, Ireland). Department of Botany, 2008)Perennial ryegrass (Lolium perenne L.) is a member of the Poaceae family, is native to Europe, the Near East and North Africa and is grown in all the temperate climate areas of the world as a forage and turf grass. Due to ... -
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 biogeography and conservation biology of Spiranthes romanzoffiana Chamisso
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The aim of this research was to gather baseline data on Irish populations of Spiranthes romanzoffiana, a species with an uneven amphi-Atlantic distribution. The species is widespread in North America. In Europe, populations ... -
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 ... -
Systematics of Juncaceae
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The systematics of Juncaceae is investigated using morphological and molecular data. A study of the anatomy of Juncaceae is presented as anatomical descriptions of the leaves, including observations of previously undescribed ... -
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 ... -
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 ... -
Shaping the symbolic landscape : public monuments in Nairobi, 1899-1992
(Trinity College (Dublin, Ireland). Department of Geography, 2007)Geography is centrally concerned with the landscape. Landscape, in this thesis, is viewed and analysed as a cultural product, shaped by human processes and ideologies. Informed, primarily, by the cultural-historical ... -
The relationship between Ascaris lumbricoides and malaria in children aged 1-4 years
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Soil-transmitted helminths (STH) are among the most prevalent of chronic human infections worldwide. More than 1.2 billion people are thought to be infected with one or more species of STH (de Silva et al., 2003). In nature, ... -
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 ... -
Low temperature and leaf growth in grasses
(Trinity College (Dublin, Ireland). Department of Botany, 2005)The central role of temperature in regulating plant growth was investigated by analysing the temperature sensitivity of various aspects of growth in grass leaves. A study of thermal responses in the C4 grass Miscanthus ...
