3D representation of Wnt and Frizzled gene expression patterns in the mouse embryo at embryonic day 11.5 (Ts 19).
(2008)Wnt signalling is one of the fundamental cell communication systems operating in the embryo and the collection of 19 Wnt and 10 Frizzled (Fzd) receptor genes (in mouse and human) represent just part of a complex system ... -
A genetic and morphological investigation of the forces shaping the diversity and distribution of the Eurasian red squirrel, Sciurus vulgaris
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)An understanding of the factors which shape the range of, and distribution of diversity within, a species, is fundamental in understanding both the species itself, but also, the effectiveness, if needed, of conservation ... -
A light and electron microscopical study of the regenerating spinal cord of the Eel
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The present study examined the regenerative capability o f the European eel Anguill anguilla following spinal cord transection injury using both light and electron microscopy. The primary aim of this investigation was to ... -
A murine model for celebral toxocariasis : characterisation of susceptibility, behaviour and immune response
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Toxocara canis, the parasitic roundworm of dogs, can infect a number of paratenic hosts, such as mice and humans, due to the widespread dissemination of its ova in the environment (Glickman and Schantz, 1981). In the murine ... -
A study on the endocrine disrupting effect of estrogenic compounds on the zebra mussel, (Dreissena polymorpha) : an in vivo/in vitro approach
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Endocrine disruption (ED) by environmental estrogens has become a major research area in environmental toxicology after the discovery that chemicals entering the environment had a feminising effect on exposed male animals. ... -
Abnormal fetal muscle forces result in defects in spinal curvature and alterations in vertebral segmentation and shape
(2017)The incidence of congenital spine deformities, including congenital scoliosis, kyphosis, and lordosis, may be influenced by the in utero mechanical environment, and particularly by fetal movements at critical time-points. ... -
Abnormal Notochord Branching is Associated with Foregut Abnormalities in an Adriamycin Treated Mouse Model
(University of Edinburgh (datashare), 2011)Oesophageal atresia (OA) and tracheooesophageal fistula (TOF) are relatively common human congenital malformations of the foregut where the oesophagus does not connect with the stomach and there is an abnormal connection ... -
Abnormal notochord branching is associated with foregut malformations in the adriamycin treated mouse model.
(University of Edinburgh (datashare), 2011)Oesophageal atresia (OA) and tracheooesophageal fistula (TOF) are relatively common human congenital malformations of the foregut where the oesophagus does not connect with the stomach and there is an abnormal connection ... -
Activation of host constitutive immune defence by an intestinal trypanosome parasite of bumble bees
(Cambridge University Press, 2003)Many parasites have to survive the harsh environment of insect guts to complete their life-cycle. Important parasites of man and animals pass part of their life cycle in insect guts and hence understanding how insects ... -
Addressing fundamental behavioural and welfare issues associated with zoo housed animals : using lowland tapirs Tapirus terrestrius and giraffes Giraffa camelopardalis as model species
(Trinity College (Dublin, Ireland). Department of Zoology, 2002)Introduction: Zoos, living museums and menageries have been around since early Egyptian and Roman times. Throughout the ages zoos have developed a more important role than merely exhibits. Nowadays, zoos serve a major role ... -
Advancing understanding and prediction in multiple stressor research through a mechanistic basis for null models
(Wiley, 2018)Global environmental change is driven by multiple anthropogenic stressors. Conservation and restoration require understanding the individual and joint action of these stressors to evaluate and prioritize management measures. ... -
An integrated assessment of estrogenic endocrine disruption in the Irish marine envrionment, with particular emphasis on chemical measurements
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)Scientific awareness of the presence and effects of endocrine disrupting compounds (EDCs) has increased in recent decades. Many gaps in the knowledge still exist, particularly in relation to concentrations and potential ... -
An investigation into the ecology of the pine marten (Martes martes) in Killarney National Park
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)The majority of the research for this thesis was carried out on a reestablished population of pine marten in Killarney National Park (KNP). I explored the success of the translocation and used distributional, biometric and ... -
An investigation into the short-term effects of environmental enrichment on the behaviour of psittacines in captivity
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)There is a lack of quantitative information available about the effects of environmental enrichment on avian orders, compared with the amount of similar research carried out on mammals. This is particularly surprising where ... -
An investigation of strain differences in Pomphorhynchus laevis (acanthocephala) : an ecological, morphological and molecular approach
(Trinity College (Dublin, Ireland). Department of Zoology, 2003)Kennedy, Bates and Brown (1989) stated that in the British Isles the acanthocephalan, Pomphorhynchus laevis could be separated into three strains, an English, Irish and marine strain. Much ecological evidence exists in ... -
Applying quantitative methods to conservation planning : Population dynamics of the Eurasian otter in Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)As appears typical in the field of conservation biology, the current study has parallel aims. The first is to improve both the limited toolbox and the biological information available for the conservation of a vulnerable ... -
Ascaris and ascariasis
(2011)Ascaris lumbricoides and Ascaris suum are widespread parasitic nematodes of humans and pigs respectively. Recent prevalence data suggests that approximately 1.2 billion people are infected. Adult worms exhibit an overdispersed ... -
Ascaris co-infection does not alter malaria-induced anaemia in a cohort of Nigerian preschool children.
(2013)BACKGROUND: Co-infection with malaria and intestinal parasites such as Ascaris lumbricoides is common. Malaria parasites induce a pro-inflammatory immune response that contributes to the pathogenic sequelae, such as ... -
Assessing novel cultivation methods, baseline fish assemblages and survey methodologies of cultivated and wild kelp in the Southwest of Ireland
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2023)Kelp (i.e. large brown macroalgae of the order Laminariales) are important habitat-forming species in coastal ecosystems. Recently, the key role kelp play as part of an expanding blue economy has been recognised in addition ... -
Assessment of scallop (Pecten maximus) stocks in the Irish and Celtic seas
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Spatially explicit approaches (differing from the traditional stock assessment theory) to the assessment of scallop off the southeast coast of Ireland were developed. Different stock assessments methods were presented with ...
