Testing DNDC model for simulating soil respiration and assessing the effects of climate change on the CO2 gas flux from Irish agriculture
(2011)Simulation models can be valuable to investigate potential effects of climate change on greenhouse gas emissions from terrestrial ecosystems. DNDC (the DeNitrification-DeComposition model) was tested against observed soil ... -
Testing indicators of biodiversity for plantation forests
(2013)In many parts of the world, plantations make up a considerable proportion of the total forest area. In such regions, the identification of high biodiversity value stands and of management practices to enhance biodiversity ... -
Testing the utility of an organic geochemical approach to Holocene sea-level change in the Shannon estuary
(Trinity College (Dublin, Ireland). Department of Geology, 2013)This project tests a recently developed, geochemically-based technique for relative sea- level (RSL) reconstruction to assess its applicability in the Shannon region. The technique is underpinned by the identification of ... -
Thank you for not flowering: conservation genetics and gene flow analysis of native and non-native populations of Fraxinus (Oleaceae) in Ireland
(2014)The risks of gene flow between interfertile native and introduced plant populations are greatest when there is no spatial isolation of pollen clouds and phenological patterns overlap completely. Moreover, invasion probabilities ... -
The application of high temporal resolution data in the management of eutrophic water-bodies in agricultural catchments
(Trinity College (Dublin, Ireland). Department of Geography, 2015)Additions of phosphorus (P) and nitrogen (N), from anthropogenic sources, enrich freshwaters and promote the growth of algae, reducing water quality. Despite the implementation of remediation measures in a number of ... -
The biogeography and conservation biology of Spiranthes romanzoffiana Chamisso
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The aim of this research was to gather baseline data on Irish populations of Spiranthes romanzoffiana, a species with an uneven amphi-Atlantic distribution. The species is widespread in North America. In Europe, populations ... -
The carbon cycle of an energy crop : Miscanthus x giganteus
(Trinity College (Dublin, Ireland). Department of Botany, 2012)The United Nations Framework Convention on Climate Change Kyoto Protocol (1997) has driven research towards a reduction of carbon dioxide (CO2) emissions and the development of alternative energy sources. Energy crops ... -
The carboniferous geology of the Carrick-on-Suir syncline, Southern Ireland
(Trinity College (Dublin, Ireland). Department of Geology, 1980)A geological map of the Carrick-on-Suir Syncline is presented at a scale of 1:31680 (2 inches to one mile). The thirteen mapping units proposed are discussed in detail; all but the lowermost are Carboniferous in age. The ... -
The changing role of Irish urban planning under a neoliberal agenda : evidence from Dublin
(Trinity College (Dublin, Ireland). Department of Geography, 2012)This research is concerned with Irish urban planning; in particular, it investigates how the neoliberal consensus was adopted on the political agenda in the 1980s by infusing economic policy at the central state ... -
The characterisation of genetic diversity of a collection of perennial ryegrass (Lolium perenne L.)
(Trinity College (Dublin, Ireland). Department of Botany, 2008)Perennial ryegrass (Lolium perenne L.) is a member of the Poaceae family, is native to Europe, the Near East and North Africa and is grown in all the temperate climate areas of the world as a forage and turf grass. Due to ... -
The characterisation of genetic diversity of common ash (Fraxinus excelsior L.) in Ireland and around Europe
(Trinity College (Dublin, Ireland). Department of Botany, 2005)Fraxinus excelsior (ash) is a native tree species in Ireland and is economically important for the production of timber that is strong, elastic and light. Having migrated after the last glaciation from mainland Europe, it ... -
The contribution of nitrous oxide emissions from Irish agriculture to global warming
(Trinity College (Dublin, Ireland). Department of Botany, 2007)Results from this thesis concern the calculation of annual fluxes and emission factors of the greenhouse gas nitrous oxide from two agricultural soils in Co. Carlow, Ireland. For a cut and grazed pasture in 2004, the annual ... -
The development of a mouse model to explore resistance and susceptibility to early Ascaris suum infection
(Trinity College (Dublin, Ireland). Department of Zoology, 2006)Ascaris suum and Ascaris lumbricoides are widespread geohelminths of pigs and humans, respectively, resulting in severe morbidity and possible mortality. The contribution of migrating A. suum larvae to liver damage has ... -
The development of alternative farm enterprises : a study of organisations and farm businesses involved in the process of farm diversification
(Trinity College (Dublin, Ireland). Department of Geography, 2002)This Thesis examined the process of farm diversification. In particular, it focused on the development of 'on-farm' alternative enterprises (AFEs). These were defined as non-traditional enterprises which involved the ... -
The development of aquatic macroinvertebrate communities in two artificial wetlands on Irish cutaway bog, with particular reference to Corixidae (Hemiptera Heteroptera)
(Trinity College (Dublin, Ireland). Department of Zoology, 2001)Two cutaway water bodies in mid-west County Offaly were studied. Turraun, created in 1990/1991, has an estimated area of 52-60 ha and an average depth of 0.5 to 1 m. The wetland sediment is predominantly peat with some ... -
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. ... -
The diet of the Eurasian badger (Meles meles) in the Republic of Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2008)After a comprehensive analysis of the diet, the Eurasian badger (Meles meles) in the Republic of Ireland was found to display the foraging behaviour of a generalist forager. This description was considered to be appropriate ... -
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 ... -
