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 ... -
Dietary conservatism in passerines : the influence of novel odour and novel colour
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)This research was concerned with the way that passerine bird species use odour cues in isolation and in combination with colour cues to make decisions about new foods. Galliformes are known to demonstrate a disproportionately ... -
Single cell analysis of tail regeneration in Ambystoma mexicanum
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)This present study examined tail regeneration in the Mexican salamander Ambystoma mexicanum, on a single cell level in vivo. The primary aim of this study was to understand where the cells were coming from to replace all ... -
The impact of neuronal activity manipulations on recovery after complete spinal transection in the Eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Spinal cord injury is a tragically debilitating event affecting up to 5 or more out of every 100,000 people in many countries across the globe. Axotomised neurons in the mammalian CNS are unfortunately unable to regenerate ... -
A light and electron microscopical study of the regenerating spinal cord of the Eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The present study examined the regenerative capability o f the European eel Anguill anguilla following spinal cord transection injury using both light and electron microscopy. The primary aim of this investigation was to ... -
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 ... -
Morphological change in nucleus accumbens neurons as a basis for the development of haloperidol-induced movement disorders
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)A syndrome of involuntary, hyperkinetic abnormal movements called tardive dyskinesia (TD) develop in predisposed individuals following treatment and withdrawal from neuroleptic drugs. These movements are primarily orofacial ... -
The ecology of the family Chydoridae (Branchiopoda, Anomopoda) and its application to lake monitoring
(Trinity College (Dublin, Ireland). Department of Zoology, 2000)Chydorids (Branchipoda, Anomopoda) were sampled from twenty nine Irish lakes between June 1996 and July 1997, in order to assess the usefulness of this group as indicators of lake ecological quality. The lakes represented ... -
The parasite community structure of stocked and wild brown trout (Salmo trutta L.)
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The present study examined the parasite component and infracommunities of wild and stocked brown trout from an experimental fishery, Lough Feeagh and compared them to the parasite component and infracommunities of wild ... -
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 ... -
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 ... -
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 ... -
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, ...
