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 ... -
Effects of retinoic acid excess on expression oh Hox 2.9 and Krox 20 and on morphological segmentation in the hindbrain of mouse embryos
(Nature Publishing Group, 1991)Mouse embryos were exposed to maternally administered RA on day 8.0 or day 7 3/4 of development, i.e. at or just before the differentiation of the cranial neural plate, and before the start of segmentation. On day 9.0, the ... -
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 ... -
Eutrophication weakens stabilizing effects of diversity in natural grasslands
(2014)Studies of experimental grassland communities have demonstrated that plant diversity can stabilize productivity through species asynchrony, in which decreases in the biomass of some species are compensated for by increases ... -
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 ... -
Evolution in the understorey: The Sulawesi babbler Pellorneum celebense (Passeriformes: Pellorneidae) has diverged rapidly on land-bridge islands in the Wallacean biodiversity hotspot
(2021)Tropical islands hold great treasures of Earth's biodiversity, but these fragile ecosystems may be lost before their diversity is fully catalogued or the evolutionary processes that birthed it are understood. We ran ... -
The evolutionary pathway to obligate scavenging in Gyps vultures
(PLoS, 2011)The evolutionary pathway to obligate scavenging in Gyps vultures remains unclear. We propose that communal roosting plays a central role in setting up the information transfer network critical for obligate scavengers in ... -
The evolutionary significance of long copulation duration in bumble bees
(EDP Sciences, 2005)Copulation duration ? the time spent in copula ? is of particular interest in social insects. Female social insects (or queens) generally only mate during a short, initial post-emergence period, and in the absence of ... -
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 ... -
Expression of the mouse labial-like homeobox-containing genes, Hox 2.9 and Hox 1.6, during segementation of the hindbrain
(Company of Biologists, 1991)The sequence of a mouse Hox 2.9 cDNA clone is presented. The predicted homeodomain is similar to that of the Drosophila gene labial showing 80 % identity. The equivalent gene in the Hox 1 cluster is Hox 1.6 which shows ... -
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. ... -
Fish body sizes change with temperature but not all species shrink with warming
(2020)Ectotherms generally shrink under experimental warming, but whether this pattern extends to wild populations is uncertain. We analysed ten million visual survey records, spanning the Australian continent and multiple decades ... -
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 ...
