Abstract
The tiger moth, Arctia caja, has been caught in the large RIS network of UK light-traps for 30 years. Annual abundance has declined since 1984, with conservation implications. Analysis using original statistical models will detect and measure, annually, patches of relatively large abundance and gap areas where the moth is rare. Several hypotheses concerning this spatial clustering will be tested. The project will use new techniques to characterise annual spatial pattern and develop novel spatio-temporal methods to measure its change from year to year. Further hypotheses will test for relationships between important changes in spatial pattern and a range of driving variables including abundance, incidence, vegetation and climate.
