A comparison of climate and vegetation dynamics in central Ireland and NW Spain since the mid-Holocene
(Trinity College (Dublin, Ireland). Department of Botany, 2008)This research investigates chmate and vegetation dynamics in two Atlantic regions; central Ireland and NW Spain. Atmospheric and oceanic processes influence climate and hence vegetation through forcing factors operating ... -
A study of taxonomy of Salicornia L. in Ireland
(Trinity College (Dublin, Ireland), 1964)Introduction: The genus Salicornia is a notoriously difficult group. The number and nature of the taxa recognised, especially within the annual section of the genus, has varied considerably according to the differing ... -
A systematic revision of the Santalaceae R. Br. of Southeast Asia
(Trinity College (Dublin, Ireland). Department of Botany, 2001) -
A systematic revision of the Uvaria L. group (Annonaceae) in Continental Asia
(Trinity College (Dublin, Ireland). Department of Botany, 2001)The goal of this research project has been to complete a taxonomic revision of Uvaria L. (Annonaceae) and its affiliates in Continental Asia. Research was based primarily at the Trinity College Herbarium. Research visits ... -
A taxanomic revision of tribe Ocimeae Dumort. (Labiatae) in continental South East Asia
(Trinity College (Dublin, Ireland). Department of Botany, 2001)This thesis aims to provide a complete account of the tribe Ocimeae for Thailand, Laos, Vietnam, Cambodia and Burma. In addition, the relevant generic problems of Ocimeae in continental South East Asia are outlined, and ... -
Application of genomic tools for Irish pasture improvement
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2018)The conventional way to improve populations in perennial ryegrass (Lolium perenne), the most important forage grass in Ireland, is through recurrent selection. However, despite breeding for nearly a century, the rate of ... -
Assessing soil respiration in the soil profile. A study case of gradient-based CO2 efflux and subsurface production rates using soil diffusion chambers
(Trinity College (Dublin, Ireland). Department of Botany, 2010)The impact of global warming on soil respiration is strongly related to the characteristics of deep-soil carbon and may differ with soil depth. Environmental parameters can affect the rates of soil CO2 respiration not only ... -
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, ... -
Biodiversity impacts of legume-supported cropping in Europe
(Trinity College (Dublin, Ireland). Department of Botany, 2016)Current global biodiversity loss is mainly driven by anthropogenic activities including land use change, pollution and over exploitation. Legumes have for millennia been used as a source of nitrogen in agriculture, and may ... -
Biogeography and speciation of the genus Peperomia Ruiz & Pavón in Eastern Polynesia
(Trinity College (Dublin, Ireland). Department of Botany, 2003)There are 17 Peperomia laxa within the remote islands of South-eastern Polynesia, of which 14 are endemic. Expeditions (S. Waldren 1991, S. Waldren & N. Kingston 1997, U. Bradley & N. Kingston 2000) have resulted in the ... -
Biological communities and environmental controls in a seasonal wetland habitat
(Trinity College (Dublin, Ireland). Department of Botany, 2017)In a context of global biodiversity decline, ponds have been identified as biologically rich habitats, and temporary ponds can support distinct communities of rare species. Some pond habitats, including dune slacks, are ... -
Biological N₂ fixation and N loss as N₂O and N₂ in a white clover-based system of dairy production
(Trinity College (Dublin, Ireland). Department of Botany, 2014)Pasture-based livestock production systems have a relatively large requirement for nitrogen (N) input compared to other food production systems. These inputs may consist of organic N, mineral N or biologically-fixed N. Of ... -
Characterisation and Application of Sphagnum to Indoor Agriculture Food Production Systems
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2024)In response to the impacts of climate change and global population growth on traditional food production activities, agricultural industries and government agencies are now investing significant time and funding into ... -
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 ... -
Characterising pesticide residues in floral resources for bees
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2023)Pesticide use in agriculture is one of the main factors driving pollinator declines. Bees are highly important pollinators and may be at risk from exposure to pesticide compounds while foraging for pollen and nectar. In ... -
Chemical ecology and conservation biogeography of Rhododendron ponticum L.
(Trinity College (Dublin, Ireland). Department of Botany, 2015)The general aims of this thesis were two-fold; firstly, to further knowledge on the topic of toxic nectar in plants, utilizing Rhododendron ponticum (and associated taxa) as a model for these investigations; and secondly, ... -
Conservation and molecular characterisation of Irish veteran oak (Quercus spp.) and ash (Fraxinus excelsior L.)
(Trinity College (Dublin, Ireland). Department of Botany, 2009)Three chloroplast markers and three nuclear microsatellite markers were applied to DNA samples from ash-leaf material. Less diversity was found in veteran ash than in the younger populations studied by Harboume et al (2005). ... -
Conservation biology of Colchicum autumnale L. and Campanula trachelium L. in the Nore Valley, Southeast Ireland
(Trinity College (Dublin, Ireland). Department of Botany, 2004)The conservation of plant biodiversity can only proceed effectively if it is informed by a detailed biological knowledge of the target species and their constituent populations. The overall aim of this study was to assess ... -
Conservation biology of Saxifraga hirculus L. in Ireland
(Trinity College (Dublin, Ireland). Department of Botany, 2012)A perennial herbaceous plant with a wide circumpolar distribution, Saxifraga hirculus L. has a highly fragmented distribution outside the northern Polar Regions. In Europe its range has been reduced dramatically with records ... -
