Evidence of former tree growth at Clonsast
(Trinity College (Dublin, Ireland), 1957)Six thousand years ago practically all the ground now covered by peat in the area investigated at Clonsast, County Offaly, was woodland. The main object of the research was to trace the disappearance of woodland due to ... -
The origin and evolutionary history of the turlough form of Ranunculus repens
(Trinity College (Dublin, Ireland). Department of Botany, 2004)Turloughs are temporary lakes that occur in karstic limestone areas predominantly in the West of Ireland. They generally flood with groundwater in Autumn and empty through swallow holes in late Spring. This strong ecological ... -
The characterisation of genetic diversity of a collection of perennial ryegrass (Lolium perenne L.)
(Trinity College (Dublin, Ireland). Department of Botany, 2008)Perennial ryegrass (Lolium perenne L.) is a member of the Poaceae family, is native to Europe, the Near East and North Africa and is grown in all the temperate climate areas of the world as a forage and turf grass. Due to ... -
The biogeography and conservation biology of Spiranthes romanzoffiana Chamisso
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The aim of this research was to gather baseline data on Irish populations of Spiranthes romanzoffiana, a species with an uneven amphi-Atlantic distribution. The species is widespread in North America. In Europe, populations ... -
Systematics of Juncaceae
(Trinity College (Dublin, Ireland). Department of Botany, 2008)The systematics of Juncaceae is investigated using morphological and molecular data. A study of the anatomy of Juncaceae is presented as anatomical descriptions of the leaves, including observations of previously undescribed ... -
Low temperature and leaf growth in grasses
(Trinity College (Dublin, Ireland). Department of Botany, 2005)The central role of temperature in regulating plant growth was investigated by analysing the temperature sensitivity of various aspects of growth in grass leaves. A study of thermal responses in the C4 grass Miscanthus ... -
The emergence of green infrastructure as promoting the centralisation of a landscape perspective in spatial planning: the case of Ireland
(2017)The ‘landscape’ approach to planning and design has long since advanced a social-ecological perspective that conceives ecosystems health and human well-being as mutually constitutive. However, conventional public sector ... -
Urban transformation with TURAS open innovations; opportunities for transitioning through transdisciplinarity
(2016)Transitioning is a unidirectional process of mainstreaming sustainability within normative societal behaviour, which communities hope will build resilience, reduce our dependence on distant resources and lead to the ... -
Farmland abandonment in Europe: an overview of drivers, consequences and assessment of the sustainability implications.
(2018)In the last decades, there have been large areas of agricultural land that were abandoned in Europe, producing significant social and environmental impacts. Land abandonment is a dynamic process, which is influenced by a ... -
Novel ecosystems: challenges and opportunities for the Anthropocene
(2016)Novel ecosystems are ecological assemblages that emerge in anthropogenic landscapes where an ecological abiotic or biotic threshold has been passed and can no longer be restored to a previous state. In such landscapes, ... -
When the public good conflicts with an apparent preference for unsustainable behaviour
(2011)The example of peatlands is used to demonstrate the challenges facing the sustainable management of natural resources in situations where the fragility of an environment is not appreciated by all stakeholders. We reveal, ... -
Incorporating socio-economic factors into restoration: Implications from industrially harvested peatlands
(2011)In establishing effective restoration goals one of the four key issues of increased attention that Hobbs (2007) calls for is in the area of incorporating socio-economic investigations and theories into restoration practice ... -
Focus group discourses in a mined landscape
(2010)Focus group research is rarely used for examining environmental discourses other than when conflict arises. This study looks at local citizen perceptions in relation to mined (or ‘cutaway’) industrial peatland landscapes ... -
Conflicting rationalities, knowledge and values in scarred landscapes
(2009)Incorporating public or local preferences in landscape planning is often discussed with respect to the difficulties associated with accurate representation, stimulating interest and overcoming barriers to participation. ... -
Developing a field boundary evaluation and grading system in Ireland
(2003)The purpose of this study was to develop an evaluation and grading system for the main field boundaries in Ireland – hedgerows and dry stone walls. It is shown that there is a lack of scientific information on Irish field ... -
The effects of elevated CO2 and water stress on C2 pasture species (Blepharis linariifolia and Cenchrus biflorus) native to Sudan
(Trinity College (Dublin, Ireland). Department of Botany, 2001)A doubling of the pre-industrial atmospheric CO2 concentration (~280 ppmv) is expected by the middle of this century, if the current rate of growth in the annual emission of fossil carbon is maintained. The effects of ... -
Morphological and molecular systematics of the genus Miscanthus anderss
(Trinity College (Dublin, Ireland). Department of Botany, 2001)Increasing fuel costs and a depletion of the earth's natural energy resources have lead to a global search for alternative sources of renewable energy. In response, the "European Miscanthus network" funded by the European ... -
