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 ... -
Identification of a high diversity of Cryptosporidium species, genotypes and subtypes in a Nigerian Pediatric Population
(2010)A longitudinal study was conducted to determine the epidemiology of Cryptosporidium in 1,636 children in Nigeria. Oocyst prevalence ranged from 15.6% to 19.6% over one year. Cryptosporidium hominis (34), C. parvum (25), ... -
Identification of Mechanosensitive Genes during Embryonic Bone Formation.
(2008)Although it is known that mechanical forces are needed for normal bone development, the current understanding of how biophysical stimuli are interpreted by and integrated with genetic regulatory mechanisms is limited. ... -
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 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 ... -
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 ...
