Assessing effects of climate change on marine ecosystems
(i.e., biological communities) is
a major challenge, mainly because (1) future changes in physical
forcing, such as water temperature, will exceed historically observed
values, and (2) biological responses or adaptations to these changes
are highly uncertain, particularly over a long time period. Changes
in geographic ranges, vertical distributions, phenologies, population
structures, and productivities will differ among individual species
thereby altering the connectivities and functions of ecosystem
components, including predator-prey relationships and competition,
species assembly, community structure, biodiversity, energy flow,
and carrying capacity. This session will focus on retrospective
analyses of changes in freshwater, coastal, and offshore ecosystems/communities,
experimental studies on species interactions under climate-change-related
conditions, and conceptual and numerical modelling of ecosystems
relevant to climate change.
