Isolation and characterisation of novel fungal root endophytes from Elymus repens (Poaceae) for resistance to Fusarium, Gaeummanomyces and Pyrenophora
(Trinity College Dublin. School of Natural Sciences. Discipline of Botany, 2019)Barley diseases are predominantly controlled using genetic resistance and fungicides. However, pathogen populations are becoming increasingly tolerant to the active compounds in fungicides and the European Union is endorsing ... -
The role of biodiversity in the functioning of plant-pollinator interactions in semi-natural grasslands
(Trinity College (Dublin, Ireland). Department of Botany, 2013)The importance of biodiversity for healthy ecosystem functioning and the provision of ecosystem services is well recognized and loss of biodiversity is increasingly being recognised as a major driver of ecosystem change. ... -
The epidemiology of Cryptosporidium species in a Nigerian paediatric population
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)Cryptosporidium is an Apicomplexan, protozoan parasite, infecting the gastroepithelium of many vertebrate hosts, including man, and is the causative agent of the diarrhoeal disease cryptosporidiosis. Although infection may ... -
The study of gill disease of cultured Atlantic salmon (Salmo salar. L) in Ireland with an emphasis on the role of epitheliocystis as a causative agent : descriptive pathology, aetiology and epidemiology
(Trinity College (Dublin, Ireland). Department of Zoology, 2011)Gill disorders have emerged as one of the most important health issues in the farming of Atlantic salmon (Salmo salar) in Ireland in recent years. The aetiology of these conditions is frequently multifactorial. Environmental ... -
Modelling ecological pressures and responses in a west of Ireland lake
(Trinity College (Dublin, Ireland). Department of Geography, 2013)Effective lake management requires an understanding of aquatic ecological pressure response relationships. Deciphering the aquatic effects of multiple ecological pressures, such as climate variability and human activity, ... -
Pesticide occurrence in Irish groundwater
(Trinity College (Dublin, Ireland). Department of Geology, 2012)Groundwater pesticide occurrence was investigated within agricultural catchments and at the national scale across Ireland. Seven intensive agricultural catchments were selected, each with different physical characteristics ... -
Invertebrate-habitat associations in the Littoral and Riparian Ecotone of Lough Carra, Co. Mayo, Ireland
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)The aim of this study was to investigate the relationship between habitat structure in the land lake ecotone and the abundance and community composition of larval and adult macroinvertebrates. This was done extensively ... -
The changing role of Irish urban planning under a neoliberal agenda : evidence from Dublin
(Trinity College (Dublin, Ireland). Department of Geography, 2012)This research is concerned with Irish urban planning; in particular, it investigates how the neoliberal consensus was adopted on the political agenda in the 1980s by infusing economic policy at the central state ... -
Towards a feasible and representative pan-African research infrastructure network for GHG observations
(2018)There is currently a lack of representative, systematic and harmonised greenhouse gas (GHG) observations covering the variety of natural and human-altered biomes that occur in Africa. This impedes the long-term assessment ... -
Nitrous oxide emissions associated with land use change to bioenergy crops Miscanthus x giganteus and Phalaris arundinacea
(Trinity College (Dublin, Ireland). Department of Botany, 2013)Bioenergy crops are an increasingly popular alternative to fossil fuels for electricity and heat generation due to their substantial yields combined with low inputs of resources. As these crops are characterised by low ... -
Morphological and DNA barcoding-based studies of meiofauna community variation along the salinity gradient and response to environmental quality changes within Irish transitional waters
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)The primary focus of this thesis is to identify the changes in meiofauna community structure in response to the estuarine salinity gradient. This was achieved through morphological identification of the nematode phylum to ... -
Evaluating UK natural hazards: the national risk assessment
(UK Parliament, 2019)Despite its relatively temperate climate and stable geography, natural hazards present multiple risks to human activity in the UK. These range from small-scale local occurrences, such as landslides, through regional ... -
Investigation into the host-parasite relationship of Sphaerularia bombi and its host(s) Bombus spp.
(Trinity College (Dublin, Ireland). Department of Zoology, 2009)This thesis investigated the relationship between a parasitic nematode (Sphaerularia bombi) and its bumble bee host (Bombus spp.). The parasite is contracted by queens during their hibernation in the ground. Infected queens ... -
Effects of shoreline modification on lake littoral macroinvertebrate assemblages
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)The general aim of this study was to explore the effects of shoreline modifications on the structure of littoral macroinvertebrate assemblages in lakes, across the gradients of nutrients and alkalinity concentrations. ... -
With the eyes of history : the Natura 2000 network, acute land use conflicts, and the future of EU biodiversity policy
(Trinity College (Dublin, Ireland). Department of Geography, 2014)This thesis concerns the history of the European Union's Natura 2000 network of protected areas, established under the Birds Directive (1979) and the Habitats Directive (1992), and the light this history sheds on: the ... -
Landforms and hydrology of the lowland karst of County Roscommon, Ireland
(Trinity College (Dublin, Ireland). Department of Geography, 2009)Karst is a significant aspect of the landscape of Ireland as more the half the island is underlain by limestone. Roscommon is located in Ireland's western karstic lowlands. The majority of Roscommon is underlain by clean, ... -
Predator-prey allometry across body size and interaction dimensionality
(Trinity College (Dublin, Ireland). Department of Botany, 2015)Predator-prey interactions are an important evolutionary driver of species' form and diversity, and are a central driver of ecosystem structure. However, the context dependent nature of interactions between predators and ... -
Systematics of the genus Gmelina L. (Lamiaceae) in Southeast Asia
(Trinity College (Dublin, Ireland). Department of Botany, 2009)The systematics of Gmelina is investigated using morphological, anatomical, palynological and molecular data.The genus is revised for Southeast Asia and 31 taxa are recognised consisting of 26 species, 1 subspecies, and 4 ... -
Macroevolution with living and fossil species
(Trinity College (Dublin, Ireland). Department of Zoology, 2015)Although many biodiversity studies focus on living species, the vast majority of species that ever lived are long extinct. It is therefore crucial to combine data from both living and fossil species to fully understand ... -
Modelling the response of freshwaters to catchment-scale phosphorus loading and mitigation in the Irish Ecoregion
(Trinity College (Dublin, Ireland). Department of Geography, 2012)Freshwater eutrophication, caused by over-enrichment by P as a result of anthropogenic activity, is increasing worldwide. In response, ROMs that seek to reduce and reverse eutrophication and its effects through the mitigation ...
