Reproductive biology of the invasive exotic shrub, Rhododendron ponticum L. (Ericaceae)
(Blackwell, 2007)The reproductive biology of an exotic species will affect its ability to become naturalized and invasive in non-native habitats. Rhododendron ponticum is an ecologically damaging exotic weed in the British Isles, which ... -
Reproductive seasonality of the male and female Eurasian badger, Meles meles
(Trinity College (Dublin, Ireland). Department of Zoology, 2010)The ecology of the Eurasian Badger (Meles meles) is highly diverse; varying greatly between geographical regions, populations and even adjoining groups. It has been argued that mating systems result from individual strategies ... -
Research trends in ecosystem services provided by insects
(2018)Insects play a key role in the regulation and dynamics of many ecosystem services (ES). However, this role is often assumed, with limited or no experimental quantification of its real value. We examined publication trends ... -
Restoration of native woodland in former conifer plantations
(Trinity College (Dublin, Ireland). Department of Botany, 2003)The majority of Irish forests are plantations of exotic conifer species, with semi-natural woodlands occupying less than 1% of Ireland. Recent land-use changes, in particular the expansion of National Parks and Nature ... -
Restricted participation: Drivers, experiences and implications of disability stigma in Ethiopia
(2023)Background: Community-based inclusive development (CBID) acknowledges society’s critical role in supporting the active participation of persons with disabilities. However, research on how this approach relates to the ... -
Revision of the Liverwort genus Asterella P. Beauv. (Marchantiales, Aytoniaceae) in Continental Eurasia, Malesia and Japan
(Trinity College (Dublin, Ireland). Department of Botany, 2001)This study constitutes a taxonomic revision of the genus Asterella in Eurasia, Asterella belongs to the family Aytoniaceae in the Chambered Liverworts (Marchantiales). It is poorly understood taxonomically and a worldwide ... -
Revisiting the Y-3 tephrostratigraphic marker: a new diagnostic glass geochemistry, age estimate, and details on its climatostratigraphical context
(2015)The ‘Y-3’ tephra is a crucial stratigraphic marker within the central Mediterranean region that falls close to the Marine Isotope Stage 3/2 transition and a cooling event proposed as a correlative of the North Atlantic ... -
Rhizophydites matryoshkae gen. et sp. nov. (fossil Chytridiomycota) on spores of the early land plant Horneophyton lignieri from the Lower Devonian Rhynie chert
(2021)Premise of research: As our understanding of the importance of fungi in ecosystems today increases, we are still in the early stages of appreciating their roles in the past. The famous Early Devonian Rhynie chert contains ... -
Rift flank uplift at the Gulf of California: No requirement for asthenospheric upwelling
(2014)Continental rifts are commonly flanked by zones of high elevation, but the cause of uplift remains controversial. Proposed uplift mechanisms include active and induced asthenospheric upwelling, and isostatically driven ... -
Rising CO2 drives divergence in water use efficiency of evergreen and deciduous plants
(American Association for the Advancement of Science (AAAS), 2019)Intrinsic water use efficiency (iWUE), defined as the ratio of photosynthesis to stomatal conductance, is a key variable in plant physiology and ecology. Yet, how rising atmospheric CO2 concentration affects iWUE at broad ... -
Risk assessment of genetically modified crops in Ireland : investigations of pollen dispersal from oilseed rape (Brassica napus L.) using molecular and pollen trapping techniques
(Trinity College (Dublin, Ireland). Department of Botany, 2004)A risk assessment was carried out to help determine the extent of pollen flow from a crop of oilseed rape (OSR, Brassica napus L). The project aimed to develop a better understanding of the potential risks of gene flow ... -
The role of amorphous precursors in the crystallization of La and Nd carbonates
(2015)Crystalline La and Nd carbonates can be formed from poorly-ordered nanoparticulate precursors, termed amorphous lanthanum carbonate (ALC) and amorphous neodymium carbonate (ANC). When reacted in air or in aqueous solutions ... -
The Role of Contemporary CO2 Sublimation as a Geomorphic Agent on Mars
(Trinity College Dublin. School of Natural Sciences. Discipline of Geography, 2019)The Martian surface is geomorphologically active, with a variety of mass?wasting, erosional and depositional features that form and change in the current climate. Many of these features have analogues on Earth (e.g. ... -
The role of helminth parasites in host invasion: a freshwater fish system
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)With the incidence of species invasions set to increase in the coming decades, it is increasingly important that research on invasive species impacts captures the complexity of natural ecosystems, including the influence ... -
The role of Intelectin-2 in resistance to Ascaris suum lung larval burdens in susceptible and resistant mouse strains
(2011)The underlying mechanism of predisposition to Ascaris infection is not yet understood but host genetics are thought to play a fundamental role. We investigated the association between the Intelectin-2 gene and resistance ... -
The role of REE3+ in the crystallization of lanthanites
(2014)The formation of crystalline rare earth element (REE) (e.g. La, Ce, Pr, Nd) carbonates from aqueous solutions was examined at ambient temperature using UV-Vis spectrophotometry, combined with X-ray diffraction, high-resolution ... -
A route for the direct crystallization of dolomite
(2015)The direct crystallization of dolomite from an aqueous solution at temperatures between 60–220 °C was followed in situ through time-resolved synchrotron-based energy-dispersive X-ray diffraction combined with offline ... -
Ryegrass organelle genomes : phylogenomics and sequence evaluation
(Trinity College (Dublin, Ireland). Department of Botany, 2010)Perennial ryegrass (Lolium perenne L.) is the most important forage grass of temperate regions of the world. The main objective in breeding perennial ryegrass cultivars is to increase its biomass. Chloroplasts and ...
