Description
Summary:Tanymastix stagnalis is known from seven locations in Ireland. These range from small to large temporary water bodies. It was earlier shown that the best hatching and survival of eggs and young stages occurred in the presence of soil and at temperatures between about 10 degree and 15 degree . Some eggs hatched after one drying period, others after up to at least 4 drying and wetting periods. It was found from field observations that the habitat appeared after a minimum of 200 mm of rain in a 2-month period. A computer model was constructed using field data, and meteorological data (rainfall and temperature) covering 100 years. This showed that in both habitats there was little likelihood of extinction from meteorological causes.
