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 ... -
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 ... -
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 ... -
Individual- and community-level responses of littoral macroinvertebrates to lake nutrient enrichment
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)The aim of this study was to investigate the response of littoral macroinvertebrates to nutrient enrichment across 66 Irish lakes representing a broad nutrient gradient. It was hypothesised that an increase in lake trophic ... -
Integrative avian taxonomy and the role of competition in the diversification of passerine birds
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)It is well recognised that the avifauna of Asia are in major need of taxonomic reassessment. The Sulawesi region of Indonesia, renowned for its high levels of avian endemism, has been relatively overlooked by ornithological ... -
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 ... -
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 ... -
Investigation into the molecular mechanisms of a host parasite interaction between a bumblebee host and an entomoparasitic nematode
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)Sphaerularia bombi (Phylum Nematode: Order Tylenchida), an entomoparasitic nematode, infects and parasitises bumblebee (Bombus) queens (Phylum Arthropoda: Order Hymenoptera) resulting in dramatic physiological and behavioural ... -
Lake littoral macroinvertebrate biomass and community structure across alkalinity and nutrient gradients
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The aim of this study was to investigate the effects of alkalinity and nutrients on the biomass of lake littoral macroinvertebrate communities. An initial comparative study of nine lakes determined the effect of alkalinity ... -
Lessons learned from the integration of Strategic Environmental Assessment with transport planning in Athens, Dublin and London
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Strategic Environmental Assessment (SEA) refers to the identification and evaluation of the positive and negative effects of actions at a higher decision making level than development projects such as programmes, plans and ... -
Littoral macroinvertebrates in lakes : patterns of distribution and potential use in ecological assessment
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The forthcoming European Council Directive establishing a framework on water policy will require Member States to monitor the ecological status of lakes. Biotic as well as physicochemical criteria must be included in ... -
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 ... -
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 ... -
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 ... -
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 ...
