Identifying future zoonotic disease threats: Where are the gaps in our understanding of primate infectious diseases?
(2013)BACKGROUND AND OBJECTIVES: Emerging infectious diseases often originate in wildlife, making it important to identify infectious agents in wild populations. It is widely acknowledged that wild animals are incompletely ... -
Ignoring discards biases the assessment of fisheries' ecological fingerprint.
(2013)Understanding the pressures of fisheries on the ecosystem is crucial for effective management. Fishery removals, or catch, are composed of both landings and discards. However, the use of discards data in studies investigating ... -
The impact of host starvation on parasite development and population dynamics in an intestinal trypanosome parasite of bumble bees
(Cambridge University Press, 2005)Host nutrition plays an important role in determining the development and success of parasitic infections. While studies of vertebrate hosts are accumulating, little is known about how host nutrition affects parasites of ... -
Impact of repeated four-monthly anthelmintic treatment on Plasmodium infection in preschool children: a double-blind placebo-controlled randomized trial
(2010)Background: Helminth infections can alter susceptibility to malaria. Studies need to determine whether or not deworming programs can impact on Plasmodium infections in preschool children. Methods: A double-blind ... -
The impact of roadworks on the ranging behaviour of European badgers (Meles meles)
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2018)The European badger (Meles meles), one of Ireland’s most iconic native species, acts as a wildlife reservoir of Mycobacterium bovis, the causative agent of tuberculosis in cattle. Badgers have been implicated in the spread ... -
Impacts of inbreeding on bumblebee colony fitness under field conditions
(BioMed Central, 2009)BACKGROUND: Inbreeding and the loss of genetic diversity are known to be significant threats to small, isolated populations. Hymenoptera represent a special case regarding the impact of inbreeding. Haplodiploidy may permit ... -
The importance of foetal movement for co-ordinated cartilage and bone development in utero : clinical consequences and potential for therapy.

The important of parasites in the functioning of warming ecosystems
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)Parasites play a critical role in the structure and functioning of ecosystems, contributing to overall ecosystem stability and the provision of ecosystem services. As the global climate changes, it is of considerable ... -
Individual- and community-level responses of littoral macroinvertebrates to lake nutrient enrichment
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)The aim of this study was to investigate the response of littoral macroinvertebrates to nutrient enrichment across 66 Irish lakes representing a broad nutrient gradient. It was hypothesised that an increase in lake trophic ... -
The influence of inoculum size and time post-infection on the number and position of Toxocara canis larvae recovered from the brains of outbred CD1 mice
(2001)Outbred CD1 mice were administered doses of 1000 and 3000 Toxocara canis eggs and postmortem took place on days 7, 42 and 120 post-infection. Mice were killed by cervical dislocation and brains were sagitally bisected and ... -
The influence of mouse strain, infective dose and larval burden in the brain on activity in Toxocara-infected mice
(2001)Outbred LACA mice and inbred NIH mice were administered low (100 ova), medium (1000 ova), high (3000 ova) and trickle (4x250 ova) doses of Toxocara canis ova and the effect of infection on activity was examined with respect ... -
Integrated analysis of Wnt signalling system component gene expression
(2022)Wnt signalling controls patterning and differentiation across many tissues and organs of the developing embryo through temporally and spatially restricted expression of multi-gene families encoding ligands, receptors, ... -
Integrative avian taxonomy and the role of competition in the diversification of passerine birds
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)It is well recognised that the avifauna of Asia are in major need of taxonomic reassessment. The Sulawesi region of Indonesia, renowned for its high levels of avian endemism, has been relatively overlooked by ornithological ... -
Interaction of the CNC-bZIP factor TCF11/LCR-F1/Nrf1 with MafG: binding-site selection and regulation of transcription
(1998)We have previously shown that the widely expressed human transcription factor TCF11/LCR-F1/Nrf1 interacts with small Maf proteins and binds to a subclass of AP1-sites. Such sites are required for b-globin 54 DNase I ... -
Interspecific interactions between Acanthocephala in the intestine of brown trout : are they more frequent in Ireland?
(2003)The aim of this paper was to test the hypothesis that when the 2 species of Acanthocephalan Pomphorhynchus laevis and Acanthocephalus clavula are found concurrently within the intestine of brown trout under field conditions, ... -
Invertebrate-habitat associations in the Littoral and Riparian Ecotone of Lough Carra, Co. Mayo, Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)The aim of this study was to investigate the relationship between habitat structure in the land lake ecotone and the abundance and community composition of larval and adult macroinvertebrates. This was done extensively ... -
Investigating the mechanistic basis of biomechanical input controlling skeletal development: exploring the interplay with Wnt signalling at the joint
(University of Edinburgh (datashare), 2018)Embryo movement is essential to the formation of a functional skeleton. Using mouse and chick models, we previously showed that mechanical forces influence gene regulation and tissue patterning, particularly at developing ... -
Investigating the underlying mechanism of resistance to Ascaris infection
(2011)The generative mechanism(s) of predisposition to Ascaris infection are currently unknown. While many factors play a role in interindividual infection intensity, much focus has been placed on the host's immunological response ... -
Investigation into the host-parasite relationship of Sphaerularia bombi and its host(s) Bombus spp.
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)This thesis investigated the relationship between a parasitic nematode (Sphaerularia bombi) and its bumble bee host (Bombus spp.). The parasite is contracted by queens during their hibernation in the ground. Infected queens ... -
Investigation into the molecular mechanisms of a host parasite interaction between a bumblebee host and an entomoparasitic nematode
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)Sphaerularia bombi (Phylum Nematode: Order Tylenchida), an entomoparasitic nematode, infects and parasitises bumblebee (Bombus) queens (Phylum Arthropoda: Order Hymenoptera) resulting in dramatic physiological and behavioural ...
