Modelling Hurricane Exposure and Wind Speed on a Mesoclimate Scale: A Case Study from Cusuco NP, Honduras.
(2014)High energy weather events are often expected to play a substantial role in biotic community dynamics and large scale diversity patterns but their contribution is hard to prove. Currently, observations are limited to the ... -
Nectar chemistry modulates the impact of an invasive plant on native pollinators
(2016)1. Invasive species are considered a main driver of pollinator declines, yet the direct effects of invasive alien plants on pollinators are poorly understood. 2. Abundant, invasive plant species can ... -
The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts.
(2014)Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status ... -
Genetic diversity and floral width variation in introduced and native populations of a long-lived woody perennial
(2014)Populations of introduced species in their new environments are expected to differ from native populations, due to processes such as genetic drift, founder effects and local adaptation, which can often result in rapid ... -
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 ...
