Evaluating the utility of 15N and 18O isotope abundance analyses to identify nitrate sources: A soil zone study
(2012)15N and 18O isotope abundance analyses in nitrate (NO3?) (expressed as ?15N-NO3? and ?18O-NO3? values respectively) have often been used in research to help identify NO3? sources in rural groundwater. However, questions ... -
Groundwater nitrate reduction versus dissolved gas production: A tale of two catchments
(2017)At the catchment scale, a complex mosaic of environmental, hydrogeological and physicochemical characteristics combine to regulate the distribution of groundwater and stream nitrate (NO3−). The efficiency of NO3− removal ... -
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 ... -
Marriage exchanges, seed exchanges, and the dynamics of manioc diversity
(2011)The conservation of crop genetic resources requires understanding the different variables-cultural, social, and economic-that impinge on crop diversity. In small-scale farming systems, seed exchanges represent a key mechanism ... -
Molecular genetic typing reveals further insights into the diversity of animal-associated Staphylococcus aureus
(2009)Staphylococcus aureus is an important pathogen of man, but is also able to colonize and cause disease in a wide variety of mammals and birds. An extended multilocus sequencing approach, involving multilocus sequence typing ... -
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 ... -
Next Generation Sequencing Reveals the Expression of a Unique miRNA Profile in Response to a Gram-Positive Bacterial Infection
(2013)MicroRNAs (miRNAs) are short, non-coding RNAs, which post-transcriptionally regulate gene expression and are proposed to play a key role in the regulation of innate and adaptive immunity. Here, we report a next generation ... -
Organic dairy farming: impacts on insect-flower interaction networks and pollination
(2011)1. Pollination interactions comprise a network of connections between ?owers and insect visitors. They are crucial for reproductive success in many angiosperms but are threatened by intensive agricultural practices. ... -
Pathogenomic analysis of the common bovine Staphylococcus aureus clone (ET3): emergence of a virulent subtype with potential risk to public health
(University of Chicago Press, 2008)A common clone (ET3) of Staphylococcus aureus is responsible for a large proportion of cases of bovine mastitis and occasionally causes zoonotic infections of humans. In the present study, we report the identification of ... -
Patterns and drivers of groundwater and stream nitrate concentrations in intensively managed agricultural catchments
(2022)The environmental loss of nitrogen in agricultural landscapes has pervasive consequences, including human health implications, eutrophication, loss of habitat biodiversity and greenhouse gas emissions. The efficacy of ...
