The nitrous oxide and methane emissions from Miscanthus x giganteus and Salix viminalis x schwerinii in Oakpark, Carlow, Ireland
(Trinity College (Dublin, Ireland). Department of Botany, 2012)In investigating the reduction of the national greenhouse gas (GHG) footprint by replacing fossil fuels with bioenergy crops it is important to have a full GHG budget. We compared field emissions of nitrous oxide (N2O) ... -
Assessing the impact of climate change on the net ecosystem exchange of Irish grasslands : a case study of CO₂ efflux using multiple microcosm enclosure facilities
(Trinity College (Dublin, Ireland). Department of Botany, 2013)It is now widely accepted that human activity is having a discernible effect on the global climate, and these changes will impact upon the functioning of many of the planet's natural systems (Cox et al, 2000; Trumbore, ... -
Water level fluctuations and their effects on lake ecology
(Trinity College (Dublin, Ireland). Department of Zoology, 2013)Escalating freshwater demand, triggered by population and economic growth, technological development, urbanization, land conversion and intensification of agriculture is one of the major challenges facing humankind. The ... -
Genetics, climate and phylogeography : understanding the Hiberno-Iberian distribution of Daboecia cantabrica (Huds). K. Koch and Erica mackaiana Bab. (Ericaceae)
(Trinity College (Dublin, Ireland). Department of Botany, 2013)Dahoecia cantahrica (Huds.) K. Koch and Erica mackaiana Bab. are two ericaceous species whose disjunct distribution in Europe is best described as Hiberno-Iberian. Both species have their origins in the Atlantic coastal ... -
Towards a future of sustainable consumption : a practice oriented, participatory backcasting approach for sustainable washing and heating practices in Irish households
(Trinity College (Dublin, Ireland). Department of Geography, 2013)How to encourage a shift to more sustainable practices of household water and energy consumption and what these practices might involve is at the heart of this thesis. While production processes and resource efficiency ... -
Irish housing and the global financial crisis of urbanisation
(Trinity College (Dublin, Ireland). Department of Geography, 2013)Due to a confluence of consecutive crisis events in Ireland since the global financial crisis of 2008 and under the greatly contracted credit cycle and debt-crisis of the Euro-area, global capital flows into Ireland's built ... -
Impacts of the alien invasive Rhododendron ponticum L. on native plants, pollinators and their interaction
(Trinity College (Dublin, Ireland). Department of Botany, 2009)This thesis addresses the impacts of an alien invasive plant. Rhododendron ponticum L., on pollination processes and population dynamics of native Irish plant and pollinator communities. Field studies were conducted in ... -
Ryegrass organelle genomes : phylogenomics and sequence evaluation
(Trinity College (Dublin, Ireland). Department of Botany, 2010)Perennial ryegrass (Lolium perenne L.) is the most important forage grass of temperate regions of the world. The main objective in breeding perennial ryegrass cultivars is to increase its biomass. Chloroplasts and ... -
Food risk governance in Ireland : regulation, communication and biosecurity
(Trinity College (Dublin, Ireland). Department of Geography, 2013)Issues of biosecurity (commonly defined as "making life safe") are relevant to the arena of food risk governance. Certainly, the complex and varied food safety controls that exist today can be described as attempting to ... -
Plant diversity and conservation in alpine areas of Kanchenjunga Conservation Area, Nepal
(Trinity College (Dublin, Ireland). Department of Botany, 2013)This thesis describes the plants and vegetation composition of alpine areas of Kanchenjunga Conservation Area, Nepal and relates the pattern to environmental variables. It evaluates the effects of various environmental ... -
The ins and outs of manioc divertsity in Gabon, Central Africia : a pluridisciplinary approach to the dynamics of genetic diversity of Manihot esculenta Crantz (Euphorbiaceae)
(Trinity College (Dublin, Ireland). Department of Botany, 2010)Manioc (Manihot esculenta Crantz subsp. esculenta, Euphorbiaceae) is the staple food and livelihood of more than half a billion people around the world, and ranks third, just behind rice and maize, as a source of calories ... -
Characterisation of Miscanthus genetic resources : a combined analysis of plastid and nuclear microsatellites, nrDNA sequences, flow cytometry and morphology
(Trinity College (Dublin, Ireland). Department of Botany, 2012)Miscanthus is a highly important forage and horticultural genus of perennial grasses (Poaceae) primarily native to South East Asia. Miscanthus is under intense global investigation as a biomass source for renewable energy ... -
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 ... -
Conservation of selected legally protected and red-listed bryophyte species in Ireland
(Trinity College (Dublin, Ireland). Department of Botany, 2013)This thesis focussed on the conservation of ten rare and threatened bryophyte species in Ireland using three separate, but complementary conservation approaches to provide an integrated strategy to ensure their survival ... -
Spatial variation of floodplain vegetation in Nong thung thong Non-Hunting Area, peninsular Thailand
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2019)This thesis aims to gain increased understanding of the processes that govern plant species composition and structure of floodplain vegetation in Nong thung thong Non-Hunting Area, one of the last few patches of floodplain ... -
Chlorite-white Mica Pairs' composition as a micro-chemical guide to fingerprint massive sulfide deposits of the Bathurst Mining Camp, Canada
(2019)The compositions of phyllosilicates, with a focus on fluid-mobile elements, were evaluated as a means to fingerprint the Middle Ordovician metamorphosed (greenschist facies) volcanogenic massive sulfide deposits of the ... -
Chemostratigraphy Across the Triassic–Jurassic Boundary
(John Wiley & Sons, Inc, 2019)The Triassic‐Jurassic transition (~201.5 Ma) is marked by one of the largest mass extinctions in Earth’s history. This was accompanied by significant perturbations in ocean and atmosphere geochemistry, ... -
