Answers

1
marine systems need to take into account
not all species breed in the water
representation of biodiversity considering connectivity and mobility
the life cycles of each species
the population must be representative.
2
Managing ecosystems strategies include
managing threats, zoning, permits, plans, longitudinal monitoring
managing each threat individually and longitudinal studies
permits and plans for managing threats.
zoning to protect important areas
3
Ethical reasons to preserve ecosystems
to preserve fish ect
ethics is the right thing to do
Is is the right thing to do
bio rights and stewardship aesthetic
4
maximum sustainable yields and maximum economic yields are
MEY is not used in Australia
MSY is the best one to use
MEY is lower
MSY is lower
5
NGO's can be
non specific and slow to act
slow and have specific goals
slow, have no specific goal but can enforce things
specific, quick to act and have no ability to enforce
6
evaluate is to...
weight up the success / failure of something
describe how and why
list positive and negative
list key characteristics
7
In the lincon fish recapture index M is
Number of fish caught and remarked initially
has nothing to do with it
number of fish recaptured
number of fish caught the second time
8
Ways you select a marine protected area
you only need to protect economically important fish life cycles
all sites have same value
site selection, connectivity
site selection, networking connectivity, replication, spacing, size
9
The three main fisheries are
marine and freshwater
lake, ocean and recreational
artisanal, recreational and commercial
ocean, freshwater and brackish
10
NGO is a
No going to organise
non genetically origin
non government organisation
non government organisms
11
economic reasons to maintain an ecosystem include
ethical yield
ecotourism, aesthetic value
recreation, ethical yield, ecotourism
recreation, ecosystems
12
changing thermal regimes will
will only cause decreases in fish populations
will only cause decrease in fish populations
cause no change in fish populations
cause changes in fish populations
13
what are some of the indirect consequences of ocean acidification.
it only affects coral
it may crash trophic levels as it affects phytoplankton
there are none
all organisms are affected by it
14
The reasons for preserving an ecosystem include..
ecological, economic, aesthetic, ethical
ethical and ecological
ethical economic, feelings and creativity
economic and aesthetic
15
bioacumulation is
increase of toxins up the food chain
make biology possible
makes more baby fish
movement of nutrient
16
ecological refers to
not keeping ecosystems
ensure you are maintaining it economically
maintaining genetic diversity
for the economy
17
Aesthetic value is
the only reason to protect ecosystems
source of calcium
spiritual connection only
source of beauty, spiritual connection.
18
food web describes
the breeding requirements of each fish
the friends of each fish
what organisms ingest other organisms
the requirements of each animal
19
What are some of the issues caused by increased global temperatures?
increased coral bleaching
all of the above
increased algae due to more heat
increased number and severity of storms
20
primary production increases fisheries
More nutrient always results in more fish
more nutrient causes more plankton but not more fish
more fish make more babies
Because fisheries require plankton to increase juvenile populations
