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 ... -
A comparison of helminth infections as assessed through coprological analysis and adult worm burdens in a wild host
(2018)Coprological analysis is the most widely used diagnostic tool for helminth infection in both domestic and wild mammals. Evaluation of the efficacy of this technique is rare, due to the lack of availability of adult worm ... -
Eutrophication weakens stabilizing effects of diversity in natural grasslands
(2014)Studies of experimental grassland communities have demonstrated that plant diversity can stabilize productivity through species asynchrony, in which decreases in the biomass of some species are compensated for by increases ... -
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. ... -
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 ... -
Home range and habitat use by the endangered grey partridge (Perdix perdix) in the Irish midlands
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)In Ireland, an 86% decline in distribution was recorded for grey partridge (Perdix perdix) between 1968 and 1991 (Sharrock, 1976; Gibbons et al, 1993). By 1995, only two wild populations remained, in Boora, Co. Offaly and ... -
The development of aquatic macroinvertebrate communities in two artificial wetlands on Irish cutaway bog, with particular reference to Corixidae (Hemiptera Heteroptera)
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Two cutaway water bodies in mid-west County Offaly were studied. Turraun, created in 1990/1991, has an estimated area of 52-60 ha and an average depth of 0.5 to 1 m. The wetland sediment is predominantly peat with some ... -
Identification and evaluation of the captive environmental factors that affect the behaviour of Sulawesi Crested Black Macaques (Macaca Nigra)
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Observations of eight Sulawesi macaque troops in the UK and Ireland, were used in four main studies that investigated: 1) The influence of season on the behavioural expression and enclosure use of Sulawesi macaques in a ... -
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 ... -
Pest control in museums : status of collections and an evaluation of control strategies
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Information on the status of museum collections held in the British Isles suggests that over 25 million specimens are at risk from the effects of deterioration. It is widely acknowledged that this situation is reflected ... -
Grey squirrel, Sciurus carolinensis, ecology in managed broadleaved woodland
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)The American grey squirrel (Sciurus carolinensis) has caused many problems to Irish broadleaved forestry since its introduction in 1911. A survey of damage caused by the grey squirrel's habit of stripping bark from broadleaved ... -
Addressing fundamental behavioural and welfare issues associated with zoo housed animals : using lowland tapirs Tapirus terrestrius and giraffes Giraffa camelopardalis as model species
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Introduction: Zoos, living museums and menageries have been around since early Egyptian and Roman times. Throughout the ages zoos have developed a more important role than merely exhibits. Nowadays, zoos serve a major role ...
