Investigation of acid mine drainage remediation by co-treatment with municipal wastewater using the activated sludge process
(Trinity College (Dublin, Ireland). Department of Botany, 2012)Acid mine drainage (AMD) remediation by co-treatment with municipal wastewater using the activated sludge (AS) process is a new approach to remediation that utilizes the alkalinity contained in municipal wastewater and the ... -
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). ... -
Foaming control in the activated sludge process using metalbolic control
(Trinity College (Dublin, Ireland). Department of Botany, 2014)Foam production is an inherent phenomenon within the activated sludge wastewater treatment process. Whilst several different types of foams have been observed it is the presence of thick, viscous brown foams on the surface ... -
The potential of miscanthus to sequester carbon in soil : a study of carbon dynamics in soil aggregates
(Trinity College (Dublin, Ireland). Department of Botany, 2010)The growing of bioenergy crops has been widely suggested as a key strategy in mitigating anthropogenic CO2 emissions. However, the full mitigation potential of these crops cannot be assessed without taking into account ... -
Hydrochemistry and algal communities of turloughs (karstic seasonal lakes)
(Trinity College (Dublin, Ireland). Department of Botany, 2011)This thesis deals with the hydrochemistry and the algal communities in a set of 22 Irish turloughs (karstic seasonal lakes) which represent a broad hydrogeological spectrum. During a flooding season (2006/2007) turloughs ... -
Origin of year-long bean (Phaseolus dumosus Macfady, Fabaceae) from reticulated hybridization events between multiple Phaseolus species
(2016)Background and Aims Improved understanding of the secondary gene pools of crops is essential for advancing genetic gain in breeding programmes. Common bean, Phaseolus vulgaris, is a staple crop with several wild relatives ... -
Plastid genome sequencing reveals biogeographical structure and extensive population genetic variation in wild populations of Phalaris arundinacea L. in north-western Europe.
(2017)New and comprehensive collections of the perennial rhizomatous reed canary grass (Phalaris arundinacea) were made in NW Europe along north-to-south and east-to-west clines from Denmark, Germany, Ireland, Poland, Sweden and ... -
Genetic variation in Miscanthus ×giganteus and the importance of estimating genetic distance thresholds for differentiating clones
(2015)Miscanthus × giganteus (Mxg) is an important bioenergy feedstock crop, however, genetic diversity among legacy cultivars may be severely constrained. Only one introduction from Japan to Denmark of this sterile, triploid, ... -
Markers associated with heading and aftermath heading in perennial ryegrass full-sib families
(2016)Background Heading and aftermath heading are important traits in perennial ryegrass because they impact forage quality. So far, genome-wide association analyses in this major forage species have only identified a small ... -
Variation in sequences containing microsatellite motifs in the perennial biomass and forage grass, Phalaris arundinacea (Poaceae)
(2016)Forty three microsatellite markers were developed for further genetic characterisation of a forage and biomass grass crop, for which genomic resources are currently scarce. The microsatellite markers were developed from a ... -
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 ... -
Restoration of native woodland in former conifer plantations
(Trinity College (Dublin, Ireland). Department of Botany, 2003)The majority of Irish forests are plantations of exotic conifer species, with semi-natural woodlands occupying less than 1% of Ireland. Recent land-use changes, in particular the expansion of National Parks and Nature ... -
Understanding late Holocene woodland dynamics in southwestern and western Ireland through the analysis of sub-fossil insect remains
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The main aim of this research was to explore the validity of using sub-fossil insect remains as a proxy for reconstructing late Holocene woodland dynamics in southwestern and western Ireland. Three woodlands were examined ... -
The ecology of yew (Taxus baccata) in Ireland
(Trinity College (Dublin, Ireland). Department of Botany, 2003)This project stemmed primarily from the need for increased ecological knowledge of the development and regeneration of yew communities in Ireland. This was required to make informed management decisions pertaining to the ... -
The interactions between native bees and alien plants
(Trinity College (Dublin, Ireland). Department of Botany, 2009)This thesis examines the interactions between native bees, in particular bumblebees (Bombus spp.), and the alien plants they visit. Most alien plants are well integrated into the resident plant-pollinator network. They are ... -
Ground flora communities in Ireland's plantation forests : their diversity, structure and composition
(Trinity College (Dublin, Ireland). Department of Botany, 2005)Ireland is committed to the principles of Sustainable Forest Management (SFM). Inherent to these principles is the conservation and appropriate enhancement of biological diversity in the country’s plantation forests. ... -
Risk assessment of genetically modified crops in Ireland : investigations of pollen dispersal from oilseed rape (Brassica napus L.) using molecular and pollen trapping techniques
(Trinity College (Dublin, Ireland). Department of Botany, 2004)A risk assessment was carried out to help determine the extent of pollen flow from a crop of oilseed rape (OSR, Brassica napus L). The project aimed to develop a better understanding of the potential risks of gene flow ... -
Spatial and temporal fluxes of plant-nutrients in turlough soils
(Trinity College (Dublin, Ireland). Department of Botany, 2008)Turloughs are annually flooding karstic depressions which constitute ecologically important and geographically restricted ground-water dependent ecosystems, identified as priority habitats under the EU Habitats Directive. ... -
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 reproductive biology and conservation of rare orchid species in Ireland
(Trinity College (Dublin, Ireland). Department of Botany, 2008)This thesis investigates the factors that affect the conservation and reproductive biology of rare Irish orchids. Research focused on various aspects of the ecology of six species that occur throughout Ireland. Four ...
