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 ... -
Evaluating the utility of 15N and 18O isotope abundance analyses to identify nitrate sources: A soil zone study
(2012)15N and 18O isotope abundance analyses in nitrate (NO3?) (expressed as ?15N-NO3? and ?18O-NO3? values respectively) have often been used in research to help identify NO3? sources in rural groundwater. However, questions ... -
Groundwater nitrate reduction versus dissolved gas production: A tale of two catchments
(2017)At the catchment scale, a complex mosaic of environmental, hydrogeological and physicochemical characteristics combine to regulate the distribution of groundwater and stream nitrate (NO3−). The efficiency of NO3− removal ... -
High levels of gene flow and genetic diversity in Irish populations of Salix caprea L. inferred from chloroplast and nuclear SSR markers
(2014)Background Salix caprea is a cold-tolerant pioneer species that is ecologically important in Europe and western and central Asia. However, little data is available on its population genetic structure and molecular ... -
The impact artificial sub-surface drainage on greenhouse gas emissions, change in soil carbon storage and nutrient losses from grassland
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2019)Irish dairy production sector has started an expansion process while achieving a 20% reduction in the National greenhouse gas (GHG) emissions and fulfilling the Water Framework Directive. Moreover, the 30% of Irish dairy ... -
Marriage exchanges, seed exchanges, and the dynamics of manioc diversity
(2011)The conservation of crop genetic resources requires understanding the different variables-cultural, social, and economic-that impinge on crop diversity. In small-scale farming systems, seed exchanges represent a key mechanism ... -
New chloroplast microsatellite markers prove to be suitable for assessing genetic diversity of Lolium perenne and other related grass species
(2012)Background and Aims Lolium perenne (perennial ryegrass) is the most important forage grass species of temperate regions. We have previously released the chloroplast genome sequence of L. perenne ‘Cashel’. Here nine chloroplast ... -
Organic dairy farming: impacts on insect-flower interaction networks and pollination
(2011)1. Pollination interactions comprise a network of connections between ?owers and insect visitors. They are crucial for reproductive success in many angiosperms but are threatened by intensive agricultural practices. ... -
Patterns and drivers of groundwater and stream nitrate concentrations in intensively managed agricultural catchments
(2022)The environmental loss of nitrogen in agricultural landscapes has pervasive consequences, including human health implications, eutrophication, loss of habitat biodiversity and greenhouse gas emissions. The efficacy of ...
