What are the key drivers for marine protected area designations?
Natura 2000, OSPAR, CBD, marine and coastal access act 2009
26
What is the MMOs role?
Responsible for enforcing the general offence of damaging a MCZ and acts as an advisor to the regional projects and stakeholder groups
27
What can you designate as an MPA?
Marine reserves, marine conservation zones, special areas of conservation and special protection areas
28
What mobile species comes under SPAs?
Birds, mostly colonies
29
What mobile species comes under SACs?
Seals, dolphins, porpoise, whales and basking sharks
30
How did Brexit impact environmental legislation?
The Habitats directive was not implemented properly by the uk and the uk approach does not comply with EU law
31
What is unique about mobile marine species?
The move around between areas and habitats
32
What are the common mobile marine species?
fish, seabirds, turtles, marine mammals
33
What must MPA designs consider?
Representation, replication, size, dispersal/movement patterns, source-sink dynamics/open-closed population, displacement of fisheries effort and threats
34
What do you need for MPA design?
data, long term monitoring and favourable politics
35
Marine Protected area - steps
Identify the feature, survey feature, define protected area, set conservation objectives and targets, monitor then report results and review
36
What do you consider when considering a protected area for a mobile species?
What is the local, national and international legislation, what do we already know about the species, carry out focused fieldwork if needed, identify areas for protection and involve local stakeholders
37
Why is sound important in the sea?
sound travels 5 times faster underwater than in air and light penetrates only to shallow depths
38
What is sound and what is it measured in?
pressure wave and measured in frequency
39
What travels further? Low or high frequency?
Low
40
When is sound reflected?
Surface of warm water layer
41
When is sound refracted?
Cold layer of water
42
When is sound scattered?
When in cold water and hits an object
43
What comes under 'natural noise'?
Earthquakes, ice, turbulence, waves breaking, rain, bubbles and spray and marine life
44
What are the 'human noises' in the ocean?
Shipping, naval activities, recreation, fisheries, science and construction
45
What legislation is noise classed as?
Pollution under the EU marine strategy framework directive
46
Who produces the guidelines on shipping noise?
International maritime organisation
47
What direct human physical disturbance towards mammals?
Fisheries bycatch, shipping and recreational boats, ecotourism and underwater noise pollution
48
What indirect human physical disturbance towards mammals?
Toxins, organic pollution, food web changes and climate change
49
What is Annex II?
species needing special measures of protection
50
What do you call the way to keep track of dolphins?
Capture-mark-recapture
51
What is the Allee effect?
A positive relationship between components of individual fitness and the density or abundance of conspecifics
52
What is included in the Allee effect?
Age structure, birth rate, reproductive females, interbirth intervals, following declining populations
53
What do coral reef ecosystems provide?
Biodiversity hotspots, protect coastal habitats and ecosystems, nursery grounds, feeding grounds, carbon sinks
54
What is the role of the grazers in reef communities?
being a predator (feeding on coral polyps), algal specialists, omnivorous with special mouth structures and digestive structures
55
What is the importance of a grazer?
high grazing rates, space clearing, clear coral rock of algae to provide spaces for settlement and maintain low standing crop of algae that would overgrow corals
56
What is needed to have a healthy reef?
Clear water, abundant coral and species diversity
57
What does overfishing lead to?
Removal of biological limits on algal growth leading to algae dominating which leads to phase shift
58
What is the phase shift? (overfishing)
macroalgal dominance leading to turbid water, limited coral and reduced biodiversity
59
What does removing top predators cause?
allows increase in mid-level predators, extra pressure on grazing fish and unable to keep up with algal growth
60
Why is the excess nutrients bad?
Corals prefer low nutrient conditions, high nutrients cause uncontrolled algal growth leading to outcompete corals which results in phase shift
61
What percentage of the world's coral reefs have been destroyed?
20%
62
What percentage of coral reefs are at imminent risk of collapse from human pressures?
24%
63
What percentage of coral reefs are under long term threat?
26%
64
Where has the most damaged reefs?
SE asia, indian ocean and caribbean
65
What is the latin name for urchins?
diadema antillarium
66
What happens when there is a decrease in urchins?
increased algal cover and decline in reef biodiversity
67
How much has algal cover reduced from the recovery of urchins?
65%-5%
68
What is the latin name for the crown of thorns starfish?
Acanthaster planci
69
Why Conserve?
Ecosystem services lead to economic benefits and humans rely on biodiversity as well as the ethical right to conservse the marine environment.
70
What does shifting baseline syndrome mean?
Results in a drift away from true natural conditions and as a consequence a change in perception of ecological change varying from generation to generation
71
How many people rely on fish for at least 20% of their protein needs?
2.6 billion
72
Why do we need conservation?
overfishing, ocean acidification, habitat destruction, pollution and coastal development
73
What does sustainable management need to consider?
Needs to consider three key elements to succeed
74
What are the United Nations 3 pillars of sustainable development?
economic development, social, development and environmental protection
75
What is sustainable management?
management of the marine environment that encompasses all 3 pillars of sustainability
