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 ... -
The ecology of Sua pan and its flamingo populations
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)Sua pan is part of the Makgadikgadi saltpan complex, which is derived from an ancient palaeo-lake that once covered much of present-day northern Botswana. Today it is the 'sump' of an endorheic drainage system, into which ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 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 ... -
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 ... -
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 ... -
The relationship between resource elemental deficiencies and zooplankton community structure and dynamics
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)Ecological stoichiometry is the study of the balance of elements in ecological interactions and processes. Recent theoretical and experimental work suggests that consideration of stoichiometric constraints on zooplankton ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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, ...
