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 ... -
Granivorous passerines across an agricultural gradient in winter : from habitat use to community structure
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)In recent decades, agricultural intensification has had profound adverse effects on farmland biodiversity, especially within the more industrialised regions of Westem Europe. Among the most severely affected groups have ... -
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 ... -
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 ... -
Hepatic ascariasis in a mouse model of relative susceptibility
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2020)The parasitic nematode Ascaris lumbricoides infects 800 million people worldwide. The age group most affected by this parasite are children between the ages of 5 and 15 years. The symptoms of ascariasis can be broadly ... -
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 ... -
Human pressure as an ecological force across scales and systems
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)Historically, climate has been seen as the main driver of global vegetation patterns, but ecological paradigms have recently expanded to acknowledge human activity as a critical determinant of species biogeography. Today, ... -
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 ... -
