Benthic habitat mapping in the southern Irish Sea
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Habitat mapping is an extremely important area in marine science. Before we can conserve areas or consider the potential impacts of industries such as fishing, aggregates, windfarms and wave or tidal turbines, we first ... -
The biology and ecology of regionally endothermic fishes in Irish waters
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)The waters surrounding Ireland are very productive due to cold water upwellings. This has led to Irish waters supporting many livelihoods such as those in tourism and fisheries, with some specialising in catching and ... -
Changing social groups in zoo populations
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)Changes in social groups of animals in zoos occur frequently, and group structures can be changed in a variety of ways: introductions of animals, removals of animals, births and deaths. Information on procedures used to ... -
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 ... -
Defining disturbance in time : the ecological implications of varying temporal patterns of disturbances
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Prediction and mitigation of the effects of global environmental change rely primarily on our capacity to anticipate its causes and consequences. Key to this is the ability to identify and understand the mechanisms that ... -
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 ... -
Dietary Conservatism: The Influences and Determinants of Alternative Foraging Strategies
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)Dietary conservatism – the existence of alternative foraging strategies in response to novel foods – continues to be a little-known and understudied topic of animal behaviour. In every vertebrate population tested so far, ... -
Dispersal and speciation in the avian archipelago
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2022)Islands play a key role in both the evolution of new species and our understanding of that evolution. The colonisation of islands, followed by different levels of gene flow between populations, has produced a diverse ... -
The ecology and evolution of endemic shrimp in Lake Tanganyika
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)An exceptionally diverse group of shrimp species in the genera Atyella, Caridella, Limnocaridina and Macrobrachium is found in Lake Tanganyika, Africa, while the region is otherwise relatively poor in shrimp species. In ... -
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 ... -
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 ... -
The effects of season, habitat, hydroperiod and water chemistry on the distribution of turlough aquatic invertebrate communities
(University of Dublin, Trinity College, 2009)The aim of this study was to investigate the effects of season, habitat, hydroperiod and water chemistry on the distribution of turlough aquatic invertebrate communities. Twenty-two turloughs, selected as representative ... -
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. ... -
Eutrophication and phytoplankton in the Liffey Estuary and Dublin Bay
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Temperature, salinity, nutrient and chlorophyll concentrations, and Secchi depth were measured monthly at 41 stations in the Liffey estuary and Dublin Bay from June 2000 to June 2004. Analysis of nutrient composition and ... -
Evaluating the status and prospects of blue carbon in Ireland and the North-East Atlantic
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2022)Since its conception in 2011, the concept of blue carbon has been valuable to focus the field of ecosystem services on carbon sequestration by marine macrophytic communities, which has been historically overlooked. In ... -
Exploiting a mouse model to identify the mechanistic basis of resistance / susceptibility to a major gastrointestinal (GI) nematode infection of man and livestock
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Ascaris worms exhibit an overdispersed frequency distribution in their hosts. In addition, observation of re-infection ... -
Facing multiple challenges at range margins : influence of climate change, nutrient enrichment and an introduced competitor on the glacial relict, Mysis Salemaai
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)Anthropogenic climate change is arguably the most important threat to global biodiversity, and its effects are expected to escalate. Mechanisms operating at local scales remain poorly understood, likely because of the ... -
Feeding and physiological energetics of the littoral Tellinoidea of Dublin Bay
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)The littoral Tellinoids, marine bivalve clams, are an important component of the Dublin Bay ecosystem, comprising a third of benthic macrofaunal biomass and providing a key conduit in the flow of energy through the system. ... -
Functional signatures of model crustaceans in lake littoral zones in response to nutrient status and local habitat
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Littoral zones of lakes are critical for linking, physically and energetically, terrestrial and aquatic habitats. Disruption of this link through modification of lake riparian habitats can affect the structure and functioning ... -
General mechanisms for non-additivity between multiple stressors at higher temporal and biological scales
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)Multiple anthropogenic stressors threaten the diversity, stability and functioning of ecosystems worldwide. The combined effects of these stressors can, however, be surprisingly difficult to predict due to complex interactions ...
