DESCRIPTION:Climate change and other anthropogenic pressures transform\, d
 egrade\, and homogenise the biodiversity and ecosystem services of our coa
 stal marine ecosystems\, in turn also reducing opportunities for people wa
 nting to benefit from their ecosystem services. Management and conservatio
 n actions to mitigate the stressors and enhance positive ecosystem respons
 es thus help both biodiversity and people\, but often some key ingredients
  to success are missing that I explain below.\n\n1) Quantifying and predic
 ting the responses of biota at key levels of organisation (from genes to e
 cosystems) enables understanding the system we aspire to manage. For examp
 le\, tropicalisation of cold (high-latitude) reefs arises from both coral 
 range shifting and expansion of endemic corals (and other species)\, but a
 rguably\, the reassembly of communities of algae\, mollusks\, soft corals\
 , echinoderms and even reef fishes is key for provisional services but lar
 gely unquantified. In particular\, the functional perspective of change is
  important\, as users often can shift target species but require ecosystem
  integrity to flourish.\n\n2) Explicitly articulating feasible\, time-boun
 d\, and measurable management objectives are the prerequisite for sensible
  decision making. It is also typically important to embed these decisions 
 within broader theory\, legislative frameworks\, and stakeholder needs.\n\
 n3) Human brains are ill equipped to deal with the complexities of decidin
 g\, particularly when biodiversity and the number of stakeholders is high\
 , trade-offs are complicated\, and socio-ecological predictions are uncert
 ain. This is where decision support tools play an important role. I will b
 riefly explain one example that is important in spatial planning.\n\nClima
 te change\, range shifting\, local extinctions\, and changing human intere
 sts all challenge our concept of static protected areas. I will close by d
 rawing together the “ingredients” to explain how we might plan spatiot
 emporally dynamic management actions.
