Quantifying the environmental drivers of tree phenology
(Trinity College (Dublin, Ireland). Department of Botany, 2007)The prediction of growth onset is particularly complicated, because this phenophase is the end-point of a series of poorly understood physiological changes that are not directly observable, occurring while the bud is ... -
Quantifying the impacts of multiple stressors on the production of marine benthic resources
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2024)Coastal ecosystems are among the most heavily affected by climate change and anthropogenic activities, which impacts their diversity, productivity and functioning and puts many of the key ecosystem services they provide ... -
Quantifying the tolerance of chick hip joint development to temporary paralysis and the potential for recovery
(2021)Background: Abnormal fetal movements are implicated in joint pathologies such as arthrogryposis and developmental dysplasia of the hip (DDH). Experimentally induced paralysis disrupts joint cavitation and morphogenesis ... -
Quantifying woodland resource usage in the Irish midlands using archaeological and palaeoecological techniques
(Trinity College (Dublin, Ireland). Department of Botany, 2012)This thesis examines charcoal methods in relation to archaeological sites and woodland resource usage using a variety of anthracological and palaeoecological approaches as well as literary evidence at different spatial and ... -
Quantitative solid phase microextraction - Gas chromatography mass spectrometry analysis of the pesticides lindane, heptachlor and two heptachlor transformation products in groundwater
(2013)This paper describes the development and validation of a method for the determination of lindane, heptachlor and two heptachlor transformation products (exo- and endo-heptachlor epoxide) in groundwater. Samples were ... -
Quantitative studies of rock fabrics and textures in layered mafic intrusions of the British tertiary igneous province : implications for magma system emplacement and evolution
(Trinity College (Dublin, Ireland). Department of Geology, 2007)This thesis examines and considers the processes which led to magmatic layering and associated planar and linear fabrics in mafic and ultramafic rocks of four igneous centres of the British (and Irish) Palaeogene Igneous ... -
Quartz-bearing C-O-H fluid inclusions diamond: Retracing the pressure-temperature path in the mantle using calibrated high temperature IR spectroscopy
(2007)Infrared spectra of C–O–H micro-inclusions were collected from a micro-inclusion bearing diamond during step-heating and freezing experiments to examine fluid speciation as a function of pressure and temperature. The ... -
Queen-controlled sex ratios and worker-reproduction in the bumble bee Bombus hypnorum, as revealed by microsatellites
(Blackwell, 2003)Social insect colonies provide model systems for the examination of conflicts among parties with different genetic interests. As such, they have provided the best tests of inclusive fitness theory. However, much remains ... -
Radon Potential as a diagnostic tool for indoor radon hazard mapping
(2019)At over 56% of the annual effective dose, radon is the primary source of ionizing radiation exposure received by the Irish population. Although the average indoor radon concentration in Ireland has been reduced since ... -
Rapid radon potential classification using soil-gas radon measurements in the Cooley Peninsula, County Louth, Ireland
(2019)A rapid method for local-scale radon risk assessment using in situ radon soil-gas measurements and a national-scale soil permeability data set have been evaluated. We test and validate our approach in a case study on the ... -
Rare Earth Element Determination in Olivine by Laser Ablation-Quadrupole-ICP-MS: An Analytical Strategy and Applications
(2017)Olivine offers huge, largely untapped, potential for improving our understanding of magmatic and metasomatic processes. In particular, a wealth of information is contained in rare earth element (REE) mass fractions, which ... -
Rare earth elements in olivine:determination, occurrence and behaviour
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2018)Olivine is a widely occurring mineral that offers great potential for improving our understanding of geological processes. Olivine is present across a range of geologically significant settings, occurring in stony-iron ... -

Re-Os geochronology of the Neoproterozoic - Cambrian Dalradian Supergroup of Scotland and Ireland: Implications for Neoproterozoic stratigraphy, glaciations and Re-Os systematics
(2011)New Re-Os geochronology for the Ballachulish Slate Formation of the Dalradian Supergroup, Scotland yields a depositional age of 659.6 ? 9.6 Ma. This age represents the first successful application of the Re-Os system to ... -
[Re]Valuing Surplus: Transitions, technologies and tensions in redistributing prepared food in San Francisco
(2018)Attention to value, exchange and circulation has long been a central feature of trade flow analyses. More recently, scholars have sought to extend these frames to examine the ongoing movements of end-of-life goods; essentially ... -
Reaction pathways and textural aspects of the replacement of anhydrite by calcite at 25 °C
(2017)The replacement of sulfate minerals by calcium carbonate polymorphs (carbonation) has important implications in various geological processes occurring in Earth surface environments. In this paper we report the results of ... -
Reaction Pathways toward the Formation of Bastnäsite: Replacement of Calcite by Rare Earth Carbonates
(2021)The interaction of rare earth bearing (La, Nd, Dy) aqueous solutions with calcite crystals at ambient and hydrothermal conditions (25–220 °C) results in the solvent-mediated surface precipitation and subsequent pseudomorphic ... -
Reassessing transfer-function performance in sea-level reconstruction based on benthic salt-marsh foraminifera from the Atlantic Coast of NE North America
(Elsevier, 2011)The need to increase the number and distribution of sea-level records spanning the last few hundred years has led to particular interest in developing high-precision, geologically based sea-level reconstructions that capture ... -
Recent aeolian erosion and deposition in the north polar plateau of Mars.
(2007)Background: Planum Boreum, the north polar plateau of Mars, displays four extensive low-albedo regions covered with widespread se dimentary deposits that are thick enough to partly or completely suppress the signature ...
