Dispersal capacity predicts both population genetic structure and species richness in reef fishes
(2014)Dispersal is a fundamental species characteristic that should directly affect both rates of gene flow among spatially distributed populations and opportunities for speciation. Yet no single trait associated with dispersal ... -
Molecular and Phenotypic Data Support the Recognition of the Wakatobi Flowerpecker (Dicaeum kuehni) from the Unique and Understudied Sulawesi Region
(2014)Accurate estimates of species richness are essential to macroecological and macroevolutionary research, as well as to the effective management and conservation of biodiversity. The resolution of taxonomic relationships is ... -
Chemical Abrasion Applied to LA-ICP-MS U-Pb Zircon Geochronology
(2014)Zircon (ZrSiO4) is the most commonly used mineral in U–Pb geochronology. Although it has proven to be a robust chronometer, it can suffer from Pb-loss or elevated common Pb, both of which impede precision and accuracy of ... -
U-Pb LA-ICPMS dating using accessory mineral standards with variable common Pb
(2014)Precise and accurate U?Pb LA-ICPMS dating of many U-bearing accessory minerals (e.g. apatite, allanite, titanite and rutile) is often compromised by common Pb. LA-ICPMS dating of these U-bearing accessory phases typically ... -

Apatite Chlorine Concentration Measurements by LA-ICP-MS
(2014)Apatite incorporates variable and significant amounts of halogens (mainly F and Cl) in its crystal structure, which can be used to determine the initial F and Cl concentrations of magmas. The amount of chlorine in the ... -
Landscape evolution at a young rifted margin: the Loreto region of Baja California Sur, Mexico.
(Imperial College LondonImperial College London, 2012)Continental rifts are commonly flanked by zones of high elevation. Proposed uplift mechanisms include active and induced asthenospheric upwelling, and isostatically driven lithospheric flexure. Although these hypotheses ... -
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 ... -
Effects of over-winter green cover on groundwater nitrate and dissolved organic carbon concentrations beneath tillage land
(Elsevier, 2012)Application of over-winter green cover (e.g. cover crops) as a measure for reducing nitrate losses from tillage land has been frequently investigated, especially in the unsaturated zone. Monitoring of groundwater is less ... -
Bayesian stable isotope mixing models
(2013)In this paper, we review recent advances in stable isotope mixing models (SIMMs) and place them into an overarching Bayesian statistical framework, which allows for several useful extensions. SIMMs are used to quantify the ... -
Modelling the Development of Rocky Shoreline Profiles along the Northern Coast of Ireland
(2013)A mathematical wave-erosion model is used to simulate postglacial shoreline profiles along the rocky, high energy coast of the north of Ireland. The wave erosion model is driven by a suite of relative sea-level (RSL) curves ... -
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 ... -
Metabolic rate and body size are linked with perception of temporal information.
(Elsevier, 2013)Body size and metabolic rate both fundamentally constrain how species interact with their environment, and hence ultimately affect their niche. While many mechanisms leading to these constraints have been explored, their ... -
The effects of land drainage on groundwater resources in karstic areas of Ireland
(Geological Publishing House, Beijing, China, 1988)The impact of land drainage on groundwater resources is particularly acute in karst areas because of the unique characteristics of karstic aquifers. Arterial drainage of karst lowlands in Ireland, involving the construction ... -
Simplifying and improving the extraction of nitrate from freshwater for stable isotope analyses
(Royal Society of Chemistry, 2011)Determining the isotopic composition of nitrate (NO3 ) in water can prove useful to identify NO3 sources and to understand its dynamics in aquatic systems. Among the procedures available, the `ion-exchange resin method? ... -
Variations in travel time for N loading to groundwaters in four case studies in Ireland: Implications for policy makers and regulators
(2009)Mitigation measures to protect waterbodies must be implemented by 2012 to meet the requirements of the EU Water Framework Directive. The efficacy of these measures will be assessed in 2015. Whilst diffuse N pathways between ... -
Unsaturated zone travel time to groundwater on a vulnerable site
(2005)A bromide (Br) tracing experiment was conducted to ascertain unsaturated zone travel time to groundwater on a site with a karstified limestone aquifer overlain by a thin free-draining overburden. Br tracer was applied to ...
