The role of helminth parasites in host invasion: a freshwater fish system
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)With the incidence of species invasions set to increase in the coming decades, it is increasingly important that research on invasive species impacts captures the complexity of natural ecosystems, including the influence ... -
The value of ex situ collections for global biodiversity conservation in the wild
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)Despite the best efforts of conservation practitioners global biodiversity is continuing to decline. The role of zoos and aquariums in conserving global biodiversity ex situ has become increasingly important as more species ... -
Hepatic ascariasis in a mouse model of relative susceptibility
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2020)The parasitic nematode Ascaris lumbricoides infects 800 million people worldwide. The age group most affected by this parasite are children between the ages of 5 and 15 years. The symptoms of ascariasis can be broadly ... -
The helminth parasites of Irish badgers: An untold story
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2020)The European badger (Meles meles) is a member of the Mustelid Family and Ireland?s largest terrestrial carnivore. Since the identification of badgers as wildlife reservoirs of bovine tuberculosis (bTB), extensive research ... -
The ecology and evolution of endemic shrimp in Lake Tanganyika
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)An exceptionally diverse group of shrimp species in the genera Atyella, Caridella, Limnocaridina and Macrobrachium is found in Lake Tanganyika, Africa, while the region is otherwise relatively poor in shrimp species. In ... -
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 ... -
Temporal and spatial dynamics of fisheries discards from Irish waters
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)There is worldwide recognition that fisheries discards (i.e. the portion of the catch returned to sea) are not only a waste of resources but are also responsible for numerous adverse ecological impacts in the marine ... -
Mechanoregulation of joint morphogenesis : investigating the role of muscle induced mechanical forces in the regulation of differentiation and growth in the avian knee joint
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Muscle induced mechanical forces have been implicated as an important regulator in the development of the skeleton. Immobilisation studies have demonstrated that in the absence of muscle contraction, skeletal elements are ... -
Facing multiple challenges at range margins : influence of climate change, nutrient enrichment and an introduced competitor on the glacial relict, Mysis Salemaai
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)Anthropogenic climate change is arguably the most important threat to global biodiversity, and its effects are expected to escalate. Mechanisms operating at local scales remain poorly understood, likely because of the ... -
The epidemiology of Cryptosporidium species in a Nigerian paediatric population
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)Cryptosporidium is an Apicomplexan, protozoan parasite, infecting the gastroepithelium of many vertebrate hosts, including man, and is the causative agent of the diarrhoeal disease cryptosporidiosis. Although infection may ... -
The study of gill disease of cultured Atlantic salmon (Salmo salar. L) in Ireland with an emphasis on the role of epitheliocystis as a causative agent : descriptive pathology, aetiology and epidemiology
(Trinity College (Dublin, Ireland). Department of Zoology, 2011)Gill disorders have emerged as one of the most important health issues in the farming of Atlantic salmon (Salmo salar) in Ireland in recent years. The aetiology of these conditions is frequently multifactorial. Environmental ... -
Invertebrate-habitat associations in the Littoral and Riparian Ecotone of Lough Carra, Co. Mayo, Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)The aim of this study was to investigate the relationship between habitat structure in the land lake ecotone and the abundance and community composition of larval and adult macroinvertebrates. This was done extensively ... -
Morphological and DNA barcoding-based studies of meiofauna community variation along the salinity gradient and response to environmental quality changes within Irish transitional waters
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)The primary focus of this thesis is to identify the changes in meiofauna community structure in response to the estuarine salinity gradient. This was achieved through morphological identification of the nematode phylum to ... -
Investigation into the host-parasite relationship of Sphaerularia bombi and its host(s) Bombus spp.
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)This thesis investigated the relationship between a parasitic nematode (Sphaerularia bombi) and its bumble bee host (Bombus spp.). The parasite is contracted by queens during their hibernation in the ground. Infected queens ... -
Effects of shoreline modification on lake littoral macroinvertebrate assemblages
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)The general aim of this study was to explore the effects of shoreline modifications on the structure of littoral macroinvertebrate assemblages in lakes, across the gradients of nutrients and alkalinity concentrations. ... -
Macroevolution with living and fossil species
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Although many biodiversity studies focus on living species, the vast majority of species that ever lived are long extinct. It is therefore crucial to combine data from both living and fossil species to fully understand ... -
Water level fluctuations and their effects on lake ecology
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)Escalating freshwater demand, triggered by population and economic growth, technological development, urbanization, land conversion and intensification of agriculture is one of the major challenges facing humankind. The ... -
The Effects of Culling on the Badger (Meles meles) Population in Ireland.
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)The European badger (Meles meles) has also been identified as the main wildlife reservoir for bovine tuberculosis (bTB). Consequently, badgers are culled nationwide as part of the bTB eradiation scheme. The control program ... -
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 ... -
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. ...
