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 ... -
Allopolyploidy, diversification, and the Miocene grassland expansion
(2014)The role of polyploidy, particularly allopolyploidy, in plant diversification is a subject of debate. Whole-genome duplications precede the origins of many major clades (e.g., angiosperms, Brassicaceae, Poaceae), suggesting ... -
Buxus sirindhorniana sp. nov. (Buxaceae), a bicarpellate species from Thailand
(2014)A new bicarpellate Buxus species, Buxus sirindhorniana W. K. Soh, M. von Sternburg, Hodk. & J. Parn., is described from northern Thailand. This is the first reported bicarpellate species of Buxus. The pollen morphology and ... -
Studies in the recent new genus record Pseudostachyum (Poaceae: Bambusoideae) from Thailand: notes on its taxonomy, distribution and habitat
(2013)A taxonomic review of the genus Pseudostachyum Munro in Thailand is presented including a description of its morphology, geographic distribution and habitat. An illustrated description of the newly recorded species P. ... -
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 ... -
Anatomical enablers and the evolution of C4 photosynthesis in grasses
(2013)C4 photosynthesis is a series of anatomical and biochemical modifications to the typical C3 pathway that increases the productivity of plants in warm, sunny, and dry conditions. Despite its complexity, it evolved more than ... -
Surviving in a warmer world: environmental and genetic responses
(2012)There are numerous reports in the literature of advancing trends in phenophases of plants, insects and birds attributed to rising temperature resulting from human-driven climate warming. One mechanism that enables a ... -
New grass phylogeny resolves deep evolutionary relationships and discovers C4 origins
(2012)Grasses rank among the world's most ecologically and economically important plants. Repeated evolution of the C 4 syndrome has made photosynthesis highly efficient in many grasses, inspiring intensive efforts to engineer ... -
Climate-related changes in peatland carbon accumulation during the last millennium
(2013)Peatlands are a major terrestrial carbon store and a persistent natural carbon sink during the Holocene, but there is considerable uncertainty over the fate of peatland carbon in a changing climate. It is generally assumed ... -
A taxonomic revision of the genus Eragrostis (Poaceae) in Thailand
(2013)A taxonomic account of Eragrostis in Thailand is provided, in which 23 species are recognized. An artificial key to species and species descriptions is provided along with distributional and ecological data for all taxa. ... -
An association between past levels of ozone column depletion and the pollen morphology of the model angiosperm Arabidopsis thaliana L
(2013)The currently reduced stratospheric ozone layer remains sensitive to destructive anthropogenic and natural inputs. We hypothesised that a sudden increase in surface ultraviolet-B (UV-B) irradiation, as may have occurred ... -
Testing indicators of biodiversity for plantation forests
(2013)In many parts of the world, plantations make up a considerable proportion of the total forest area. In such regions, the identification of high biodiversity value stands and of management practices to enhance biodiversity ... -
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 ...
