Project Title

Biodiversity and environmental change: an integrated study encompassing a range of scales, taxa and habitats

From

Jan 2006

July 2009

Summary

This research cluster, involving researchers from eight institutions, will provide an integrative multi-disciplinary research framework for national and local biodiversity policy in Ireland. Core research in the cluster directly addresses the protection and management of ecological resources in the context of pressures that might lead to environmental change by focusing on habitat fragmentation and loss, impacts of non-native species, climate change, pollution and resource management. The research will also extend capability by developing fundamental biodiversity research and capacity building in taxonomic skills as well as biodiversity indicators and biomonitoring tools. Additionally, two cross-cutting research projects will make specific progress in the inventory and output of taxonomic data and in the understanding of political processes, including public participation, that also shape biodiversity policies. While utilising national information were appropriate primary data collection will be concentrated in the greater County Clare area to maximise integration across disciplines, habitats, taxa and drivers of change. Desk studies, workshops and working groups will synthesise current knowledge and identify priority areas for future research. Our strategic aim is to build a foundation for collaborative biodiversity research capacity in Ireland through a network of researchers delivering the high quality multidisciplinary research required for sustainable management of Ireland's biodiversity.

Project Title

Assessing the Conservation Status of Turloughs

From

Jan 2006

Jan 2010

Summary

This integrated, multidisciplinary project will for the first time integrate hydrological, biological and chemical nutrient data from selected turloughs. This novel approach will involve close collaboration between zoologists, botanists, limnologists and hydrogeologists with excellent track records of research in relevant areas. This team will collate existing disparate data, and generate a very large amount of novel data, in the key areas of: . turlough hydrology, . vegetation description, . aquatic algal and invertebrate communities, . soil and water nutrient chemistry. Standard, well-tested methodologies will be used throughout; the novel aspect of this project is in the integration of what are too often disparate disciplines. Integrated, consistent data drawn from the main research areas outlined above will be used to develop new models relating hydrology with turlough ecology, thereby providing improved ecological understanding of the main factors and processes affecting turlough biota. This will be used to formulate scientifically sound prescriptions for both monitoring and maintaining the international conservation value of this EU priority habitat.

Project Title

Plant Conservation in the Kachenjunga National Park, Nepal

From

Oct 2008

Oct 2011

Summary

This project will examine threats to the alpine plant communities, their traditional use by indigenous ethnic minority groups, and devise ways of ensuring conservation of the regions highly specialised plant diversity while also ensuring the sustainable livelihoods of local communities

Project Title

Conservation biology of Trichomanes speciosum

From

Oct 2008

Apr 2012

Summary

This project, a collaboration between the National Botanic Gardens and TCD, will examine the conservation biology of the Killarney Fern (Trichomanes speciosum), a species listed on the EU Habitats Directive. The project will develop appropriate monitoring protocols for the independent gametophyte and sporophyte generations, examine the level of threat to different populations, and assess the genetic diversity within and among Irish populations.

Project Title

Quantifying links between turlough vegetation community diversity and hydrology

From

Oct 2005

Oct 2008

Summary

This project will derive quantitative relationships between the vegetation of turloughs (priority EU habitats, largely restricted to Ireland) and the incidence of flooding. Vegetation communities in a range of turlough basins will be described quantitatively, thereby providing great improvement on currently available qualitative descriptions. These data will be used to describe how vegetation changes along gradients of flooding, using data derived from continuously monitored water depth in selected turlough basins, and this approach will be used to derive predictive models of turlough vegetation in relation to flooding. The information provided will help to deliver both environmental and biodiversity conservation policy.
