Abstract

Linyphiid spiders spread risks by dispersing between the shifting resources and hazards in the farmland mosaic. Life history, dispersal strategy and patterns of land use interact to determine population size and persistence. Non-linear modelling will link wind-borne dispersal and population dynamics in simulation models parameterised with experimental population dispersal data, land use data and meteorological records. Models will be validated against Rothamsted Insect Survey and genetic data and used to assess risks to regional biodiversity from local field practices. Dispersal behaviour in island and mainland populations will be studied to assess the adaptive responses of populations exposed to different levels of risk during dispersal. (Joint with grants 14032, 14034 and 14036).
