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 ... -
Dissolved carbon leaching from soil is a crucial component of the net ecosystem carbon balance
(2011)Estimates of carbon leaching losses from different land use systems are few and their contribution to the net ecosystem carbon balance is uncertain. We investigated leaching of dissolved organic carbon (DOC), dissolved ... -
The Distribution of Precious and Energy-Critical Elements at the Scale of a Porphyry Copper Deposit
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)Magmatic-hydrothermal porphyry copper deposits are the world's primary sources of Cu. Moreover, these may contain extractable concentrations of rare metal(loid)s e.g., Se, Te, In, Co, Ge, Ga, Ag, Au and Re. Some of these ... -
Do differences in the administrative structure of populations confound comparisons of geographic health inequalities?
(2010)Background: Geographical health inequalities are naturally described by the variation in health outcomes between areas (e.g. mortality rates). However, comparisons made between countries are hampered by our lack ... -
Do Results based management frameworks frustrate or facilitate effective development practice? Experiences of the Irish International Development Sector
(2019)Utilising a case study methodological approach to analyse the Irish practitioner experience, this article examines if the introduction of results-based frameworks (RBFs) have led to greater impact and accountability to ... -
Does Large Igneous Province Volcanism Always Perturb the Mercury Cycle? Comparing the Records of Oceanic Anoxic Event 2 and the End-cretaceous to Other Mesozoic Events
(2018)Mercury (Hg) is increasingly being used as a sedimentary tracer of Large Igneous Province (LIP) volcanism, and supports hypotheses of a coincidence between the formation of several LIPs and episodes of mass extinction and ... -
Does size matter? Bumblebee behaviour and the pollination of Cytisus scoparius L. (Fabaceae).
(EDP Sciences, 2000)The effects of forager body size and floral display size on pollinator behaviour were assessed in a relatively specialised plant-pollinator system. Cytisus scoparius, which has structurally complex, nectarless flowers is ... -

Dose-dependent impact of larval Ascaris suum on host body weight in the mouse model
(2009)Ascaris lumbricoides and Ascaris suum are important helminth parasites of humans and pigs, respectively. Although it is now well established that the presence of mature adult worms in the host intestine contributes to ... -

The dune effect on sand-transporting winds on Mars
(2015)Wind on Mars is a significant agent of contemporary surface change, yet the absence of in situ meteorological data hampers the understanding of surface-atmospheric interactions. Airflow models at length scales relevant to ... -
Dynamic river channel suggests a long-lived Noachian crater lake on Mars.
(2005)ecent images of the Noachian-age Holden Northeast Crater show spectacular meandering channels that form a complex 150 meter thick lacustrine river delta deposit confined to the northwest margin of the crater. We ... -
Dynamic topography of Central and Southern Africa
(Trinity College (Dublin, Ireland). Department of Geology, 2009)Africa’s basin and swell topography is thought to be dynamically supported by mantle convection because it correlates closely with long wavelength free-air gravity anomalies, which can be regarded as a proxy for the ... -
Dynamics of unusual debris flows on Martian sand dunes
(2004)Gullies that dissect sand dunes in Russell impact crater often display debris flow-like deposits in their distal reaches. The possible range of both the rheological properties and the flow rates are estimated using ... -
An Early Jurassic (Sinemurian Toarcian) stratigraphic framework for the occurrence of Organic Matter Preservation Intervals (OMPIs)
(2021)Lower Jurassic sedimentary successions in the Atlantic margin basins include several organic-rich intervals, some with source rock potential; time-equivalent units are also identified in on- and offshore areas worldwide. ... -
Early mafic magmatism and crustal anatexis on the Isle of Rum: evidence from the Am M?m intrusion breccia
(2009)The Rum Igneous Centre comprises two early marginal felsic complexes (the Northern Marginal Zone and the Southern Mountains Zone), along with the later central ultrabasic?basic layered intrusions. These marginal complexes ... -
Ecological alterations associated with Submarine Groundwater Discharge (SGD), utilising Stable Isotope Analysis (SIA)
(Trinity College (Dublin, Ireland). Department of Geography, 2014)Research was conducted in three systems over two ecoregions to examine the ecological impacts associated with SGD. The potential applications of stable isotope analysis (SIA) in the field of SGD ecological research were ... -
Ecological impacts of invasive plants on pollinators : studies on an individual, species and community scale
(Trinity College (Dublin, Ireland). Department of Botany, 2015)Pollination is a critical ecosystem service yet pollinators are experiencing worldwide declines. Although invasive alien species are cited as a major driver of pollinator declines, little is known about how pollinators are ...
