The population biology of Acanthocephalus clavula in European Eel Anguilla anguilla L., brown trout Salmo trutta L. and Asellus meridianus Rac., with special reference to the suitability of brown trout as a definitive host
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Acanthocephalus clavula is an acanthocephalan parasite of freshwater fishes which is distributed across Ireland, Great Britain and continental Europe. In Ireland, the intemiediate host of A. clavula is the isopod Asellus ... -
The relationship between Ascaris lumbricoides and malaria in children aged 1-4 years
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Soil-transmitted helminths (STH) are among the most prevalent of chronic human infections worldwide. More than 1.2 billion people are thought to be infected with one or more species of STH (de Silva et al., 2003). In nature, ... -
The relationship between resource elemental deficiencies and zooplankton community structure and dynamics
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)Ecological stoichiometry is the study of the balance of elements in ecological interactions and processes. Recent theoretical and experimental work suggests that consideration of stoichiometric constraints on zooplankton ... -
The reproductive biology, population dynamics, production and fishery of the freshwater clam Galatea paradoxa (Born, 1778) in the Volta river, Ghana.
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The reproductive biology, population dynamics and production of Galatea paradoxa (Bom 1778) (Donacidae) which is the basis of an artisanal fishery at the Volta River Estuary, Ghana, was studied from March 2008 to February ... -
The social evolution of intellect
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. In recent times two main explanatory frameworks ... -
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 ... -
The vagility of an invasive species, the grey squirrel (Sciurus carolinensis) : studies of population genetic structure, control and recolonisation, range expansion and pox virus
(Trinity College (Dublin, Ireland). Department of Zoology, 2011)About a dozen grey squirrels were introduced to Castleforbes, Co. Longford in 1911 and have since expanded their range, almost exclusively to counties east of the Shannon, at a mean rate of 1.94km/year. -
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 ... -
Toxocara in the mouse : A model for parasite-altered host behaviour ?
(2001)The objective of this paper is to critically evaluate the significance of parasite-altered host behaviour in the Toxocara mouse model particularly in the light of the Manipulation Hypothesis. Murine behaviours were examined ... -
Tramps in transition: genetic differentiation between populations of an iconic "supertramp" taxon in the Central Indo-Pacific
(2022)The island monarch ( Monarcha cinerascens) was an original example of the “supertramp strategy ”. This involves well-developed dispersal specialisation, enabling a species to colonise remote islands but leaving it competitively ... -
Transcriptome analysis of the mouse E14.5 (TS23) developing humerus and differential expression in muscle-less mutant embryos lacking mechanical stimulation
(University of Edinburgh (datashare), 2014)Mechanical stimulation is important for the correct formation of the skeleton. Splotch-delayed mutant embryos (Pax3Spd/Spd) that develop with no limb muscle and therefore no limb movement experience an altered mechanical ... -
Trophic enrichment factors for blood serum in the European badger (Meles meles)
(2012)Ecologists undertaking stable isotopic analyses of animal diets require trophic enrichment factors (TEFs) for the specific animal tissues that they are studying. Such basic data are available for a small number of species, ... -
Two domains of the human bZIP transcription factor TCF11 are necessary for transactivation

Understanding variation in ecology and physiology of marine migratory species.
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)As the world faces the threats of multiple compounded and worsening crises, scientists are racing to gather the knowledge necessary to safeguard entire ecosystems and species. Technological advances are continuously ... -
Utilisation of brown trout by Acanthocephalus clavula (Acanthocephala) in brown trout (Salmo trutta) in an Irish lake: is this evidence of a host shift?
(2004)The population biology of the fish acanthocephalan Acanthocephalus clavula was described from 161 wild brown trout, Salmo trutta sampled over a two-year period in Clogher Lake in the west of Ireland. Overall prevalence of ... -
Validation and use of a parametric model for projecting cystic fibrosis survivorship beyond observed data: a birth cohort analysis
(BMJ Group, 2011-07-22)Background: The current lifetable approach to survival estimation is favoured by CF registries. Recognising the limitation of this approach, we examined the utility of a parametric survival model to project birth cohort ... -
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 ... -
Vegetated Habitats Trophically Support Early Development Stages of a Marine Migrant Fish in a Coastal Lagoon
(2020)Understanding the trophic ecology of early developmental stages of commercial fish species migrating between sea and coastal lagoons is crucial to effective management of nursery habitats and resulting resources. While ... -
