Effects of shade on growth, biomass allocation and leaf morphology in European yew (Taxus baccata L.)
(2013)The impact of shade on the growth of European yew (Taxus baccata L.) saplings was investigated over a three-year period using artificial shading to simulate four different light regimes (3%, 7%, 27% and 100% of photosynthetically ... -
Ecological Variation in Response to Mass-Flowering Oilseed Rape and Surrounding Landscape Composition by Members of a Cryptic Bumblebee Complex.
(2013)The Bombus sensu stricto species complex is a widespread group of cryptic bumblebee species which are important pollinators of many crops and wild plants. These cryptic species have, until now, largely been grouped together ... -
Long-term changes and drivers of biodiversity in Atlantic oakwoods
(Elsevier, 2013)Atlantic oakwoods are of high conservation value in western Europe. Developing effective conservation management policies requires data on the dynamics of woodland over long time scales. Such data are not available through ... -
High levels of variation in Salix lignocellulose genes revealed using poplar genomic resources
(2013)Background Little is known about the levels of variation in lignin or other wood related genes in Salix, a genus that is being increasingly used for biomass and biofuel production. The lignin biosynthesis pathway is ... -
Microclimate moderates plant responses to macroclimate warming.
(2013)Recent global warming is acting across marine, freshwater, and terrestrial ecosystems to favor species adapted to warmer conditions and/or reduce the abundance of cold-adapted organisms (i.e., “thermophilization” of ... -
The potential for indirect effects between co-flowering plants via shared pollinators depends on resource abundance, accessibility and relatedness
(2014)Co-flowering plant species commonly share flower visitors, and thus have the potential to influence each other's pollination. In this study we analysed 750 quantitative plant–pollinator networks from 28 studies representing ... -
Spring foraging resources and the behaviour of pollinating insects in fixed dune ecosystems
(2014)In temperate climates, foraging resources for pollinating insects are especially important in early spring when animals emerge from hibernation and initiate annual life cycles. One habitat, protected under EU law, which ... -
Comparative performance of six carbon footprint models for use in Ireland.
(2009)Carbon footprint models are increasingly being used to manage personal and household carbon dioxide emissions. Six models were compared for their suitability for use in Ireland using typical data for a household of three ... -
Increased soil emissions of potent greenhouse gases under increased atmospheric CO2
(Nature, 2011)Increasing concentrations of atmospheric carbon dioxide (CO2) can affect biotic and abiotic conditions in soil, such as microbial activity and water content1, 2. In turn, these changes might be expected to alter the ... -
A catalogue of Irish pollen diagrams
(2013-09-04)The first Irish pollen diagram was published by Gunnar Erdtman in the Irish Naturalists? Journal in 1927. Since then over 471 pollen diagrams have been produced from locations throughout Ireland from a range of sites and ... -
Papaveraceae
(Royal Botanic Garden Edinburgh, 2011)The Internet-accessible account of Papaveraceae for the Flora of Nepal includes all native and fully naturalized species, detailed taxonomic information and distribution maps, and brief references to agricultural and ... -
Organic farming and landscape structure: Effects on insect-pollinated plant diversity in intensively managed grasslands
(2012)12 Hide Figures Abstract Introduction Methods Results Discussion Supporting Information Acknowledgments Author Contributions References Reader Comments (0) ... -
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 ... -
A 1000-year reconstruction of summer precipitation from Ireland: Calibration of a peat-based palaeoclimate record
(2012)Calibration of proxy climate records is well-established for annually resolved proxies such as tree rings, but it has not been attempted for non-annually resolved proxies such as those from peatland surface wetness records. ... -
An agronomic assessment of greenhouse gas emissions from major cereal crops
(2012)Agricultural greenhouse gas (GHG) emissions contribute approximately 12% to total global anthropogenic GHG emissions. Cereals (rice, wheat, and maize) are the largest source of human calories, and it is estimated that world ... -
Hondurodendron, a new monotypic genus of Aptandraceae from Honduras.
(2010)Hondurodendron C. Ulloa, Nickrent, Whitef. & D. Kelly, a new monotypic genus endemic to Honduras, is here described and illustrated. The new species, H. urceolatum C. Ulloa, Nickrent, Whitef. & D. Kelly, is a dioecious ... -
Testing DNDC model for simulating soil respiration and assessing the effects of climate change on the CO2 gas flux from Irish agriculture
(2011)Simulation models can be valuable to investigate potential effects of climate change on greenhouse gas emissions from terrestrial ecosystems. DNDC (the DeNitrification-DeComposition model) was tested against observed soil ... -
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. ... -
Dissolved carbon leaching from soil is a crucial component of the net ecosystem carbon balance
(2011)Estimates of carbon leaching losses from different land use systems are few and their contribution to the net ecosystem carbon balance is uncertain. We investigated leaching of dissolved organic carbon (DOC), dissolved ... -
Meconopsis autumnalis and M. manasluensis (Papaveraceae), two new species of Himalayan poppy endemic to central Nepal with sympatric congeners
(2011)Two new species from Nepal, Meconopsis autumnalis and M. manasluensis, are described and illustrated with notes on diagnostic characters used to distinguish them from allied species. Sympatric speciation and the mechanisms ...
