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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
The fisheries biology of commercial ray species from two geographically distinct regions
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Age, growth and maturity were investigated in the commercial ray species from two contrasting, and geographically distinct regions; namely the Falkland Islands’ ray fishery, which is recently established, carefully managed ... -
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 ... -
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 ... -

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 ... -
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 effects of increased sediment load on the Biota of Lake Tanganyika, East Africa
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Before the work described in this thesis, no studies had been done to test the direct effects of increased sediment load on the biota of Lake Tanganyika. The aim of this research was to assess the effects of increased ... -
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. ... -
