6 Main Distinctions from terrestrial reserve design
|
1. Volume
2. Huge depth stratification 3. Ocean-wide dispersal distances 4. Rapid shifts in conditions 5. Dominated by small, sensitive structures 6. Influenced by terrestrial inputs |
|
1. Volume (area and depth)
(6 main distinctions) |
-difficult to monitor and define areas (where to put boundaries?)
- EEZ - economic exclusion zones can be used - stewarded areas based on fishing |
|
2. Huge depth stratification
(6 main distinctions) |
-lack of information on depths >50m
-limited ability to survey using remote sensing techniques |
|
4. Rapid shifts in conditions
(6 main distinctions) |
-challenging to conserve habitat or key areas
- leads to a patchy distribution -dynamic features |
|
5. Dominated by small, sensitive structures
(6 main distinctions) |
- strong gradients of species and structure types from the coast
- easily degraded -hard to restore |
|
3. Ocean-wide dispersal
(6 main distinctions) |
- dealing with connectivity issues on a very large scale
- hard to understand "landscape" ecology: like what is a corridor? |
|
6. Influenced by terrestrial inputs
(6 main distinctions) |
-collects everything: runoff, toxins, pollutants
-bioaccumulation -biomagnification (big fish have increased levels of toxins like mercury) -legacy contaminants: old toxins are still being found in fish |
|
Upwelling
|
regions where cold water comes up from the deep and mixes with warmer, shallow water
- addition of cold, salty water increases productivity -a dynamic event |
|
Allee effects
|
- still important in marine environments
- broadcast spawning and larval settlements require large numbers |
|
Invasive species
|
- there are invasions in all marine environments
- probably way more than we know about |
|
Habitat fragmentation and degradation
|
- human induced: fishing and tourism
-eutrophication -trawling and dredging cause lots of waste and destruction |
