[font size=5]Loss of species makes nature more sensitive to climate change[/font]
[font size=3]High biodiversity acts as an insurance policy for nature and society alike as it increases the likelihood that at least some species will be sufficiently resilient to sustain important functions such as water purification and crop pollination in a changing environment.
"It's the same principle as an investment portfolio you'd be mad to put all your eggs in one basket," says researcher Johan Eklöf.
Experiments with eelgrass meadows in shallow inlets on the west coast of Sweden are now showing that climate change can exacerbate the negative effects of losing sensitive species, and that the insurance effect of biodiversity may be weaker than what we typically assume.
Eelgrass meadows in shallow inlets are important nursery habitats for cod, for example. Since the early 1980s the prevalence of eelgrass has fallen dramatically along the Bohuslän coast.
