    Competition Funded PhD Project (European/UK Students Only)

Project Description

Both insect and spider biodiversity are decreasing worldwide. While their terrestrial ecosystems are being damaged by numerous human activities such as agricultural intensification, urbanization, and climate change, sensory pollutants such as light and sound are further intensifying population declines.

Light pollution is a global threat; sky glow, light trespass, spatial, temporal and spectral changes have all been shown to cause disruptive and detrimental impacts on the ecology of animals. However, the effects of light pollution are under-studied, and in many cases, under-estimated. For both insects and spiders, work has generally focussed on changes to assemblage composition, effects on invertebrate fluxes and impacts on predator-prey interactions. Forinvertebrates that migrate or that navigate when foraging, an important gap in our current knowledge exists around energetic and physiological impacts and we lack direct measures of changes in individual fitness. In this PhD, two groups of nocturnal animals with contrasting ecologies provide ideal and underexploited systems: Long distance migratory moths and central-place foraging ground spiders.

Funding Notes

This is a competition funded project through the NERC GW4+ DTP. There is a competitive selection process. This studentship will cover fees, stipend and research costs for UK students and UK residents for 3.5 years.

The successful candidatewill be interested in animal behaviour, sensory ecology and the effects of global change. Applicants will have astronginterestinlearning new techniques, from light measurementsto molecular analysis and field work.
