Is there a new climate politics? Emergency, Engagement and Justice,
(2021)Addressing climate change globally requires significant transformations of production and consumption systems. The language around climate action has shifted tangibly over the last five years to reflect this. Indeed, ... -
Taxonomy and ecology of epilithic diatoms in Irish lakes
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)Benthic algae are significant primary producers and important in biogeochemical cycling in shallow lakes in particular, but epilithic diatom ecology is poorly understood compared to phytoplankton and higher trophic levels. ... -
General mechanisms for non-additivity between multiple stressors at higher temporal and biological scales
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2021)Multiple anthropogenic stressors threaten the diversity, stability and functioning of ecosystems worldwide. The combined effects of these stressors can, however, be surprisingly difficult to predict due to complex interactions ... -
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 ... -
Development of a SEM-EDS method for quantifying free mica in building materials
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2021)The publication of Irish Standard IS 465:2018 highlighted the need for a technique to accurately and non-subjectively quantify free mica. The standard was developed to assist those who intend to provide assessment and ... -
Archaeosporites rhyniensis gen. et sp. nov. (Glomeromycota, Archaeosporaceae), from the Lower Devonian Rhynie chert a fungal lineage morphologically unchanged from more than 400 million years
(2020)Background and Aims: Structurally preserved arbuscular mycorrhizas from the Lower Devonian Rhynie chert represent core fossil evidence of the evolutionary history of mycorrhizal systems. Moreover, Rhynie chert fossils of ... -
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 ... -
Morphological diversity of fungal reproductive units in the Lower Devonian Rhynie and Windyfield cherts, Scotland: A new species of the genus Windipila
(2020)The Lower Devonian Rhynie and Windyfield cherts from Scotland contain a remarkable diversity of microscopic fungal propagules and reproductive units; however, only relatively few of these fossils are described. One of them ... -
Fungi associated with Glossopteris (Glossopteridales) leaves from the Permian of Antarctica: A preliminary report
(2015)Fungi today occur on virtually every plant part, living and dead, and represent a significant proportion of fungal diversity. Arborescent seed ferns characterized by large, tongue-shaped leaves with reticulate venation ... -
Cheirolepidiaceous diversity: an anatomically preserved pollen cone from the Lower Jurassic of southern Victoria Land, Antarctica
(2015)To date, the vast majority of fossils described for the extinct conifer family, the Cheirolepidiaceae, have been reported from compression/impressions primarily from Cretaceous rocks; there are fewer reports from ... -
Arbuscular mycorrhizal fungi in a voltzialean conifer from the Triassic of Antarctica
(2015)Mycorrhizas are intimate mutualistic relationships between plants and fungi that represent an integral component of ancient and extant ecosystems. These symbioses have been established for at least 400 million years and ... -
Structurally preserved fungi from Antarctica: Diversity and interactions in late Paleozoic and Mesozoic polar forest ecosystems.
(2016)Chert and silicified wood from the Permian through Cretaceous of Antarctica contain abundant information on fungal diversity and plant–fungal interactions. The chert deposits represent a particularly interesting setting ... -
Reexamination of cell contents in Pennsylvanian spores and pollen grains using Raman spectroscopy
(2014)Permineralization offers exceptional structural preservation to the level of cellular components, many of which are found within fossilized plant specimens. In some cases, structures within plant cells, particularly those ... -
Mycorrhizal symbiosis in the Paleozoic seed fern Glossopteris from Antarctica
(2013)Mycorrhizal associations occur in almost all modern plant groups and are probably one of the most important forms of symbioses in the context of terrestrial ecology and evolution. Surprisingly, there is a paucity of ... -
Frankbaronia velata nov. sp., a putative peronosporomycete oogonium containing multiple oospores from the Lower Devonian Rhynie chert
(2013)Spherical to pyriform microfossils containing multiple smooth-walled spherules from the Lower Devonian Rhynie chert are described as oogonia of a new fossil peronosporomycete based on congruencies in basic morphology to ... -
Reinvestigating Carboniferous actinomycetes : authigenic formation of biomimetic carbonates and implications for microbial paleoecology
(2013)Paleoecological interactions among fossil microorganisms have garnered significant interest within the paleobotanical community; however, an understanding of the early diagenesis of associated plant material is of critical ... -
Microfossils from the Lower Devonian Rhynie Chert with suggested affinities to the Peronosporomycetes
(2012)A conspicuous silicified microfossil, Frankbaronia polyspora n. gen. n. sp., occurs in plant litter and as an inhabitant of microbial mats from the Lower Devonian Rhynie chert, Aberdeenshire, Scotland. Specimens are ... -
A Putative fossil zygomycetous fungus with mantled zygosporangia and apposed gametangia from the lower coal measures (Carboniferous) of Great Britain
(2013)Several specimens of a new fungal reproductive unit, Halifaxia taylorii nov. gen. et spec., occur within the tracheids of a structurally preserved fern axis from the Lower Pennsylvanian of Great Britain. The reproductive ... -
Tylosis formation and fungal interactions in an Early Jurassic conifer from northern Victoria Land, Antarctica
(2012)Well-preserved fungi occur in permineralized conifer axes from the Lower Jurassic of northern Victoria Land, Antarctica. The fungus is characterized by septate hyphae extending through the vascular ray system via penetration ...
