The developmental orgins of Tracheo-oesophageal malformations : investigating the molecular and morphological basis of foregut abnormalities in Adriamycin treated mice and in newly established 3D foregut culture system
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Oesophageal Atresia/Tracheo-oesophageal fistula (OA/TOF) is a congenital malformation that requires urgent and complex surgery soon after birth and is associated with life-long respiratory and gastro-intestinal morbidity. ... -
Parasites in a host species' invasion : a unique small mammal model system
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)It is becoming increasingly evident that biological invasions result in altered disease dynamics in invaded ecosystems, with knock-on effects for native host communities. Invasive species may acquire native parasites, ... -
The ecology of obligate scavengers from individual behaviour to population dynamics
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Studies on vultures are on the rise, and just as well given the sharp declines in many of the 23 species. Indeed it seems these population crashes are responsible for this research boost. However, there remain obvious gaps ... -
New diagnostic and prognostic biomarkers for age-related macular degeneration
(Trinity College (Dublin, Ireland). Department of Zoology, 2014)Age-related macular degeneration (AMD) is a common condition causing progressive visual impairment, leading to irreversible blindness. This condition is characterised by loss of central vision attributed to degenerative ... -
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 ... -
Changing social groups in zoo populations
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)Changes in social groups of animals in zoos occur frequently, and group structures can be changed in a variety of ways: introductions of animals, removals of animals, births and deaths. Information on procedures used to ... -
Lake littoral macroinvertebrate biomass and community structure across alkalinity and nutrient gradients
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The aim of this study was to investigate the effects of alkalinity and nutrients on the biomass of lake littoral macroinvertebrate communities. An initial comparative study of nine lakes determined the effect of alkalinity ... -
Defining disturbance in time : the ecological implications of varying temporal patterns of disturbances
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Prediction and mitigation of the effects of global environmental change rely primarily on our capacity to anticipate its causes and consequences. Key to this is the ability to identify and understand the mechanisms that ... -
The social evolution of intellect
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)The high levels of intelligence seen in humans, other primates, certain cetaceans and birds remain a major puzzle for evolutionary biologists, anthropologists and psychologists. In recent times two main explanatory frameworks ... -
The vagility of an invasive species, the grey squirrel (Sciurus carolinensis) : studies of population genetic structure, control and recolonisation, range expansion and pox virus
(Trinity College (Dublin, Ireland). Department of Zoology, 2011)About a dozen grey squirrels were introduced to Castleforbes, Co. Longford in 1911 and have since expanded their range, almost exclusively to counties east of the Shannon, at a mean rate of 1.94km/year. -
Visualisation of abnormal morphological development and molecular mechanisms that give rise to tracheo-oesophageal malformations and other VACTERL anomalies in an Adriamycin treated Mouse Model
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)Oesophageal atresia/Tracheo-oesophageal fistula (OA/TOF) are relatively common malfonnations of the foregut in humans (Spitz, 2007). They require urgent corrective surgery after birth and have an impact on the future health ... -
The reproductive biology, population dynamics, production and fishery of the freshwater clam Galatea paradoxa (Born, 1778) in the Volta river, Ghana.
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The reproductive biology, population dynamics and production of Galatea paradoxa (Bom 1778) (Donacidae) which is the basis of an artisanal fishery at the Volta River Estuary, Ghana, was studied from March 2008 to February ... -
The population biology of Acanthocephalus clavula in European Eel Anguilla anguilla L., brown trout Salmo trutta L. and Asellus meridianus Rac., with special reference to the suitability of brown trout as a definitive host
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Acanthocephalus clavula is an acanthocephalan parasite of freshwater fishes which is distributed across Ireland, Great Britain and continental Europe. In Ireland, the intemiediate host of A. clavula is the isopod Asellus ... -
Littoral macroinvertebrates in lakes : patterns of distribution and potential use in ecological assessment
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)The forthcoming European Council Directive establishing a framework on water policy will require Member States to monitor the ecological status of lakes. Biotic as well as physicochemical criteria must be included in ... -
Lessons learned from the integration of Strategic Environmental Assessment with transport planning in Athens, Dublin and London
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Strategic Environmental Assessment (SEA) refers to the identification and evaluation of the positive and negative effects of actions at a higher decision making level than development projects such as programmes, plans and ... -
Reproductive seasonality of the male and female Eurasian badger, Meles meles
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The ecology of the Eurasian Badger (Meles meles) is highly diverse; varying greatly between geographical regions, populations and even adjoining groups. It has been argued that mating systems result from individual strategies ... -
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 ... -
The relationship between resource elemental deficiencies and zooplankton community structure and dynamics
(Trinity College (Dublin, Ireland). Department of Zoology, 2007)Ecological stoichiometry is the study of the balance of elements in ecological interactions and processes. Recent theoretical and experimental work suggests that consideration of stoichiometric constraints on zooplankton ... -
Benthic habitat mapping in the southern Irish Sea
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)Habitat mapping is an extremely important area in marine science. Before we can conserve areas or consider the potential impacts of industries such as fishing, aggregates, windfarms and wave or tidal turbines, we first ... -
Spatial and temporal variability in the littoral macroinvertebrate communities of selected Irish lakes
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)Five replicate samples were collected from five exposed stony shoreline sites in three low, mid and high alkalinity lakes within a narrow temporal window in order to assess the spatial variation in littoral invertebrate ...
