Global climate change: Underestimated impact of sea-level rise on habitat loss?
Global climate change is expected to cause sea-level rise of
approximately 1-2 meters within this century and studies are beginning
to project the consequences for humans and global biodiversity. While
the direct consequences of sea-level rise due to flooding and inundation
('primary effects') are beginning to be assessed, no studies have yet
considered the possible secondary effects from sea-level rise due to the
relocation of human refugees into the hinterland. Researchers from the
Konrad Lorenz Institute of Ethology of the University of Veterinary
Medicine, Vienna, with lead author Florian Wetzel and senior researcher
Dustin Penn, collaborated with scientists from the Ecoinformatics and
Biodiversity Group of Aarhus University, Denmark to assess and project
the potential secondary impacts of sea-level rise on habitat
availability and the distribution of mammals. They found that in more
populated regions secondary effects can lead to an equal or even higher
loss of habita!
primary displacement effects.
