Local‐scale tree and shrub diversity improves pollination services to shea trees in tropical West African parklands
(2020)Shea Vitellaria paradoxa trees bear fruit and seeds of considerable economic, nutritional and cultural value in the African Sudano‐Sahelian zone. In much of West Africa, shea exists within an agroforestry system referred ... -
Endophytic diversity of Fraxinus excelsior L. (European Ash) and its interaction with the dieback pathogen Hymenoscyphus fraxineus
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2020)European ash, Fraxinus excelsior, has huge economic and environmental value on the island of Ireland for forestry and ecosystem services. Given the rapid spread of Hymenoscyphus fraxineus, ash dieback disease, since its ... -
Fungicides, herbicides and bees: A systematic review of existing research and methods
(Public Library of Science, 2019)Bees and the pollination services they deliver are beneficial to both food crop production, and for reproduction of many wild plant species. Bee decline has stimulated widespread interest in assessing hazards and risks to ... -
A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland
(2020)1. Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural ... -
The trace element and U-Pb systematics of metamorphic apatite and its application in provenance studies
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)Apatite is a common accessory mineral in igneous, sedimentary and metamorphic rocks. It has potential as a provenance indicator in clastic sedimentary systems, as it can host a wide variety of trace elements in its crystal ... -
A 'Bandung' View of the World: The Political Economy of Sino-South African Megaprojects
(Trinity College Dublin. School of Natural Sciences. Discipline of Geography, 2020)China's emergence as a significant actor in Africa's political economy has become a major topic in both academic and popular circles. Precipitated by a confluence of domestic politico-economic factors and an increasingly ... -
The Land of the Chiefs and the Land of the State - What happens after an acquisition in Ghana?
(Trinity College Dublin. School of Natural Sciences. Discipline of Geography, 2020)In Africa the importance of land cannot be overstated given that many rural livelihoods depend on farming for subsistence. Yet, where international land acquisitions are concerned, the majority take place on the African ... -
Shallow sampling by multi-shot laser ablation and its application within U-Pb zircon geochronology
(2020)The interaction of incident laser radiation and sample substrate is complex and difficult to predict. Natural zircons are often both structurally and chemically heterogeneous in 3-dimensional space. Encountering growth-related, ... -
Filamentous cyanobacteria preserved in masses of fungal hyphae from the Triassic of Antarctica
(2020)Permineralized peat from the central Transantarctic Mountains of Antarctica has provided a wealth of information on plant and fungal diversity in Middle Triassic high-latitude forest paleoecosystems; however, there are no ... -
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 ... -
Multi-scale crystallographic ordering in the cold-water coral Lophelia pertusa
(2017)Lophelia pertusa is a widespread colonial cold-water coral which can form large three-dimensional habitats for benthic communities. Although it is known to construct an aragonite skeleton with optically opaque and translucent ... -
Spaces for sustainability learning? Future visioning as a geographical process for transforming production and consumption practices
(2012)Despite widely articulated concerns about unsustainable production and consumption processes, governance interventions have led to only incremental shifts in routinised production and consumption behaviour, particularly ... -
Mechanical Regulation of Skeletal Development
(University of Edinburgh (datashare), 2013)Development of the various components of a normal skeleton requires highly regulated signalling systems that co-ordinate spatial and temporal patterns of cell division, cell differentiation and morphogenesis. Much work in ... -
An investigation into the Bryozoa of Ireland including the distributional patterns of the marine Bryozoa of Ireland over the last 150 years
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)Bryozoans are sessile filter feeding marine invertebrates. Research in Ireland on bryozoans has been sparse in recent years but many studies were carried out in the early 1900's by researchers such as Albert Russell Nichols ... -
Volcanic crystals as time capsules of eruption history
(2018)Crystals formed prior to a volcanic event can provide evidence of processes leading to and timing of eruptions. Clinopyroxene is common in basaltic to intermediate volcanoes, however, its ability as a recorder of pre-eruptive ... -
Utilizing Papal Taxation Records for Geographical, Economic, and Cultural Analysis: A Study of Early Fourteenth Century Ireland
(Trinity College Dublin. School of Natural Sciences. Discipline of Geography, 2020)This project explores the economic, physical, political, and cultural geography of medieval Ireland by mapping the 1302-20 papal tax valuations of ecclesiastical benefices, with parish incomes being used as proxies for ... -
Geochemical origins of trvertines limestones in the Edward Basin, Albertine Riff DRC - Uganda
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)From 2007 to 2014, geological field surveys have been undertaken within the East African Rift System where hot spring Travertine and limestones have been discovered, precipitated at active, or palaeo-spring sites around ... -
SHARE IT: co-designing a sustainability impact assessment framework for urban food sharing initiatives
(2019)Urban food systems must undergo a significant transformation if they are to avoid impeding the achievement of UN Sustainable Development Goals. One reconfiguration with claimed sustainability benefits is ICT-mediated food ... -
Regulating urban food sharing: policy, practice and food democracy goals
(2019)Calls for greater food democracy in Europe have emerged as the limitations of urban food systems dominated by commercial organisations are documented, but little attention has been paid to how policy arrangements affect ...
