Soil carbon sequestration during the establishment-phase of Miscanthus x giganteus : a study on three spatial scales
(Trinity College (Dublin, Ireland). Department of Botany, 2013)In recent years the use of biomass for energy production has become an increasingly important measure for mitigating global change. While national and EU legislation strongly advocate the further development of the bioenergy ... -
Ecophysiology in introduced Impatiens species
(Trinity College (Dublin, Ireland). Department of Botany, 2011)This thesis aims to improve knowledge of invasion processes through investigation of the invasive strategies of congeneric Impatiens species that vary in invasive status in Ireland. Since a range of physiological traits ... -
Systematics of the Thai Vitaceae
(Trinity College (Dublin, Ireland). Department of Botany, 2010)The Vitaceae family (excluding Tetrastigma (Miq.) Planch.) are fully revised for Thailand. A total of 48 species in nine genera are revised as follows: Ampelocissus Planch., Ampelopsis Michx., Cayratia Juss., Cissus L., ... -
Systematics of Arundinelleae and Andropogoneae subtribes Chionachninae, Dimeriinae and Germainiinae (Poaceae:Panicoideae) in Thailand
(Trinity College (Dublin, Ireland). Department of Botany, 2009)This thesis has provided a comprehensive taxonomic account of tribe Arundinelleae, and subtribes Chionachninae, Dimeriinae and Germainiinae of the tribe Andropogoneae in Thailand. Complete floristic treatments of these ... -
Pollinators and pollination in changing agricultural landscapes : investigating the impacts of bioenergy crops
(Trinity College (Dublin, Ireland). Department of Botany, 2013)Pollinators, and the pollination services they provide, are essential for the reproduction of the majority of angiosperms, but also for a wide variety of crops. However pollinators are increasingly threatened by many human ... -
Turlough vegetation communities : links with hydrology, hydrochemistry, soils and management
(Trinity College (Dublin, Ireland). Department of Botany, 2012)This thesis documents the vegetation communities of 22 turloughs from Counties Galway, Clare, Roscommon and Mayo. In total, 28 vegetation communities were identified, classified and described. These communities ranged from ... -
Nitrous oxide emmissions from Irish arable soils : effects of reduced tillage, cover crop and conventional tillage
(Trinity College (Dublin, Ireland). Department of Botany, 2010)This study was carried out in Carlow, Ireland from August 2007 - August 2009 to investigate nitrous oxide (N2O) emissions from a spring barley field under different soil management regimes using a static closed chamber ... -
The effects of land-use change and management on soil nitrous oxide emissions from Miscanthus x giganteus
(Trinity College (Dublin, Ireland). Department of Botany, 2011)The use of bioenergy crops as fossil fuel replacements has expanded in the recent past and is likely to continue to grow in the near future as countries attempt to meet greenhouse gas reduction targets outlined in various ... -
Isolation and characterisation of novel fungal root endophytes from Elymus repens (Poaceae) for resistance to Fusarium, Gaeummanomyces and Pyrenophora
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2019)Barley diseases are predominantly controlled using genetic resistance and fungicides. However, pathogen populations are becoming increasingly tolerant to the active compounds in fungicides and the European Union is endorsing ... -
The role of biodiversity in the functioning of plant-pollinator interactions in semi-natural grasslands
(Trinity College (Dublin, Ireland). Department of Botany, 2013)The importance of biodiversity for healthy ecosystem functioning and the provision of ecosystem services is well recognized and loss of biodiversity is increasingly being recognised as a major driver of ecosystem change. ... -
Towards a feasible and representative pan-African research infrastructure network for GHG observations
(2018)There is currently a lack of representative, systematic and harmonised greenhouse gas (GHG) observations covering the variety of natural and human-altered biomes that occur in Africa. This impedes the long-term assessment ... -
Nitrous oxide emissions associated with land use change to bioenergy crops Miscanthus x giganteus and Phalaris arundinacea
(Trinity College (Dublin, Ireland). Department of Botany, 2013)Bioenergy crops are an increasingly popular alternative to fossil fuels for electricity and heat generation due to their substantial yields combined with low inputs of resources. As these crops are characterised by low ... -
Predator-prey allometry across body size and interaction dimensionality
(Trinity College (Dublin, Ireland). Department of Botany, 2015)Predator-prey interactions are an important evolutionary driver of species' form and diversity, and are a central driver of ecosystem structure. However, the context dependent nature of interactions between predators and ... -
Systematics of the genus Gmelina L. (Lamiaceae) in Southeast Asia
(Trinity College (Dublin, Ireland). Department of Botany, 2009)The systematics of Gmelina is investigated using morphological, anatomical, palynological and molecular data.The genus is revised for Southeast Asia and 31 taxa are recognised consisting of 26 species, 1 subspecies, and 4 ... -
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, ... -
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 ... -
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 ... -
