Abstract | Temperature is considered to be a fundamental factor controlling biodiversity in marine
ecosystems, but precisely what role temperature plays in modulating diversity is still not clear.
The deep ocean, lacking light and in situ photosynthetic primary production, is an ideal model
system to test the effects of temperature changes on biodiversity. Here we synthesize current
knowledge on temperature–diversity relationships in the deep sea. Our results from both present
and past deep-sea assemblages (including Ostracoda and other taxonomic groups) suggest that,
when a wide range of deep-sea bottom-water temperatures is considered, a unimodal
relationship exists between temperature and diversity (that may be right skewed). It is possible
that temperature is important only when at relatively high and low levels but does not play a
major role in the intermediate temperature range. Possible mechanisms explaining the
temperature–biodiversity relationship include the physiological-tolerance hypothesis, the
metabolic hypothesis, island biogeography theory, or some combination of these. The possible
unimodal relationship discussed here may allow us to identify tipping points at which on-going
global change and deep-water warming may increase or decrease deep-sea biodiversity.
Predicted changes in deep-sea temperatures due to human-induced climate change may have
more adverse consequences than expected considering the sensitivity of deep-sea ecosystems
to temperature changes. |
