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 ... -
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 ... -
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 ... -
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 ... -
The diet of the Eurasian badger (Meles meles) in the Republic of Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)After a comprehensive analysis of the diet, the Eurasian badger (Meles meles) in the Republic of Ireland was found to display the foraging behaviour of a generalist forager. This description was considered to be appropriate ... -
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 ... -
The important of parasites in the functioning of warming ecosystems
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)Parasites play a critical role in the structure and functioning of ecosystems, contributing to overall ecosystem stability and the provision of ecosystem services. As the global climate changes, it is of considerable ... -
The fisheries biology of commercial ray species from two geographically distinct regions
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Age, growth and maturity were investigated in the commercial ray species from two contrasting, and geographically distinct regions; namely the Falkland Islands’ ray fishery, which is recently established, carefully managed ... -
The effects of increased sediment load on the Biota of Lake Tanganyika, East Africa
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Before the work described in this thesis, no studies had been done to test the direct effects of increased sediment load on the biota of Lake Tanganyika. The aim of this research was to assess the effects of increased ... -
Feeding and physiological energetics of the littoral Tellinoidea of Dublin Bay
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)The littoral Tellinoids, marine bivalve clams, are an important component of the Dublin Bay ecosystem, comprising a third of benthic macrofaunal biomass and providing a key conduit in the flow of energy through the system. ... -
The impact of roadworks on the ranging behaviour of European badgers (Meles meles)
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)The European badger (Meles meles), one of Ireland’s most iconic native species, acts as a wildlife reservoir of Mycobacterium bovis, the causative agent of tuberculosis in cattle. Badgers have been implicated in the spread ... -
The multidemsionality of ecological stability
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)Ecological stability is a multifaceted concept, incorporating components such as variability, resistance, resilience, persistence, and robustness. Understanding and predicting the relationships among these many components ... -
A mechanistic basis for the mechanical regulation of skeletal development
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)Movement is essential to embryonic skeletal development. In humans, Foetal Akinesia Deformation Syndrome results when inhibited movement causes joint contractures and weakened bones susceptible to fracture. Differentiation ...
