Connectivity conservation of arthropods under global warming

The recent wave of studies demonstrating dramatic declines
in species richness, diversity and biomass of insects has caused great
concern among ecologists, conservationists, policymakers and the general
public. Climate change, and in particular global warming, puts many insect
(and other arthropod) species at risk. Persistence can only be guaranteed if
species tolerate, accommodate or adapt to changing thermal conditions, or
if they are able to track their thermal niche along the latitudinal or
altitudinal climate change gradient. Even very mobile species may,
however, be hampered here-in as the eventual connectivity between
populations will be determined by their life-history traits, dispersal and the
environmental context. This project aims to provide a quantitative
understanding of the potential limitation of arthropods to track the current
velocity of climate change, and how the current landscape composition
facilitates or constraints movement, and thus the potential spatial changes
in biodiversity patterns. This will be achieved by modeling, using a unique
virtual species approach combined with state-of-the art tracking methods.
These methods will eventually be applied to test the robustness of the
current Natura2000 networks for arthropod connectivity.
