1: forcing factors driven by aerial warming - glacier mass balance - newly ice free areas - sediment and fresh water transport 2: ecosystem response - environmental conditions - terrestrial and marine community structure and dynamics 3: species / population response - adjustment to changing conditions (abiotic, biotic) - physiological stress signals Get signal conceptual model of Antarctic Peninsula climate change effects clicOPEN IPY 34 – science plan Genetic diversity Biodiversity Trophic structure & flow Interaction strength Age/size of bivalve populations energy reserves Critical limits (T,S, Sed Cov, O2) Lifetime models of fitness params Molecular stress tags Use local data to feed spatial glacier melt models.
