  1. DOLMANT Development of ecological modelling tools for lake management Speakers: Dr Louise Vaughan & Dr Katrina Macintosh Project Leaders: Dr Yvonne McElarney & Prof Brian Rippey

  2. Presentation Overview • DOLMANT project aims • Programme of work • Phytoplankton • Zooplankton • Future work • Questions?

  3. DOLMANT Project Aims • Integrate biological, hydromorphological and physico-chemical properties of lakes with catchment variables • Models will help evaluate the effectiveness of measures adopted in catchments • Support effective programmes of measures in line with the Water Framework Directive

  4. Plus other relevant measured variables..alk, cond, pH etc… Metrics e.g. % Cyanobacteria % Chlorophytes.. Lake TP Catchment nutrient loadings… PhytoplanktonStatus Macrophyte Status Lake TN Chla Temperature Ecological State Zooplankton Status Fish Status M’Invertebrate Status

  5. Programme of Work • Lough Neagh • Lower Lough Erne • 52 smaller lakes

  6. Phytoplankton Scolban Golagh Vearty Legane Lee Mourne

  7. Lough Neagh

  8. Phytoplankton Metrics • Chlorophyll a • Percentage Nuisance Cyanobacteria • Irish EPA Phytoplankton composition metric • Phytoplankton Trophic Index

  9. Zooplankton • Lough Neagh historic samples • Two years; 2005 and 2011 were enumerated in detail. • Describe seasonal patterns of density • Establish changes between 2005 and 2011 • Changes from 1970-1990 data

  10. Lough Neagh 2005 • Cyclops spp. most abundant, followed by Eudiaptomus gracilis • D. hyalina found between July and October • D. longispina found between March and May • Bythotrephes longimanus found in July and August • Leptodora kindtii from May to August

  11. Lough Neagh 2005

  12. Lough Neagh 2011 • Cyclops spp. most abundant, followed by Eudiaptomus gracilis • D. hyalina found between July and December • D. longispina not found • Bythotrephes longimanus found from July to September • Leptodora kindtii in August and October

  13. Lough Neagh 2011

  14. Lough Neagh 1969 - 2011

  15. Future Work • Continue enumeration of historic samples from Lough Neagh and Lough Erne • Commence fieldwork on 52 small lakes • Model causal relations between lake variables using structural equation modeling (SEM) / path analysis • Develop practical management tools to assist agencies achieve ecological targets for lakes

  16. Project Partners • Agri-Food and Biosciences Institute (AFBI) • University of Ulster (UU) • Trinity College Dublin (TCD) • Inland Fisheries Ireland (IFI) • Environmental Protection Agency (EPA) • Northern Ireland Environment Agency (NIEA)
