Velocity of climate change

Question 1

Exemplify some alternative forces in the worlds oceans that are becoming barriers to adaptation?

Answer 1

• Input of nutrients such as nitrogen and phosphorus in coastal waters
• Mining
• Offshore windfarms
• Losing coral cover/mangrove areas for a host of reasons
• Heavy ship traffic

…all affect how species adjust to changing conditions.

Question 2

What is an ecotone?

What is an ecotonal boundary?

Answer 2

An ecotone is where one biome meets another.
Different biomes have different velocities (can move away from each other).

Ecotonal boundary opens - what happens in between = novel ecosystems

Question 3

Why would marine species be better at adapting to climate change?

Answer 3

Less barriers to moving around, easier to move around them.
