1[blank_start]Biodiversity[blank_end]: complete range of species and biological communities, as well as genetic variation within species and all ecosystem processes
[blank_start]Species Diversity[blank_end]: all species on Earth, from single celled bacteria to multicellular kingdoms
[blank_start]Genetic Diversity[blank_end]: genetic variation within species, both amoung geographically disparate populations and among individuals within a single population
[blank_start]Ecosystem Diversity[blank_end]: the different biological communities and their associates with the chemical and physical environment- ABiodiversity
- BSpecies Diversity
- CGenetic Diversity
- DEcosystem Diversity
2Species are generally defined in 3 ways:
- Amorphologically
- Bbiologically
- Cevolutionarily
- Dchemically
3The most diverse places on Earth include:
- Atropical rainforests
- Bcoral reefs and deep sea
- Cmediterranean-type communities
- Dbay communities
- Eopen ocean
4We are currentlyin the sixth major extinction event in Earth's history.
- AVerdadero

5Distribution and structure of terrestrial biodiversity lagged behind marine and freshwater ecosystems.
- AVerdadero
- BFalso
6Biodiversity measures:
[blank_start]Species richness[blank_end] (S)
[blank_start]Shannon Diversity[blank_end] (H')
[blank_start]Rao's quadratic entropy index[blank_end] (Q)- ASpecies richness
- BShannon Diversity
- CRao's quadratic entropy index
7Biodiversity hospots:
- Aplaces with exceptional concentrations of endiemic species
- Bhydrothermal vents, where there is high diversity
8Ecological processes that drive biodiversity:
- Areproduction
- Bgrowth
- Crecruitment
- Dvagile species
- Eagile species
- Fno apex predators
9How do you quantify species richness?
- ASum of species of a particular taxonomic grouping within an area of interest (S)
- BSum of number of species and their abundances of a particular taxonomic group with an area of interest (H')
10How do you quantify species diversity?
- ASum of number of species and their abundances of a particular taxonomic group with an area of interest (H')
- BSum of species of a particular taxonomic grouping within an area of interest (S)
11Conservation is concerned with:
- Aloss of biodiversity on every scale
- Bphylogeny and classification
- Cdiversity of species
12____________ is the change in how a system is measured against a previous reference point, which may themselves represent a significant change from an earlier state of the system
- AShifting Baseline Syndrome
- BShifting Outlook Syndrome
- CChanging Baseline Syndrome
- DChanging Outlook Syndrome
13In the [blank_start]11th[blank_end] century, England switched from [blank_start]freshwater[blank_end] to [blank_start]saltwater[blank_end] fishing. this was due both to the depletion of [blank_start]freshwater[blank_end] species and the development of new fishing [blank_start]technology[blank_end], such as better nets and boats.
- A11th
- B10th
- C12th
- D14th
- Efreshwater
- Fsaltwater
- Gsaltwater
- Hfreshwater
- Ifreshwater
- Jsaltwater
- Ktechnology
- Llocations
14Humans have profoundly affected marine wildlife, altering function and provisioning of services in every ocean
- AVerdadero
- BFalso
15Current ocean trends coupled with terrestrial defaunation lessons suggest marine defaunation rates will rapidly [blank_start]intensify[blank_end] as human use of oceans industrializes
- Aintensify
- Bdecrease
16Marine defaunation has gone too far for the ocean to recover.
- AVerdadero
- BFalso
17What is the allee effect?
- Ainverse density-dependence or depensation
- Bincreases in population density result in increased per capita population growth
- Cincreases in population density result in decreased per capita population growth
- Dlow population density, after some threshold density, population growth will decrese
18Major causes of biodiversity loss include...
- Aoverhunting/overexploitation
- Bintroduced species
- Cchains of extinctions
- Dhabitat destruction
- Eclimate change
- Fextinction synergies
- Gnatural apex predators
19Overfishing results in...
- Areduced abundance
- Bfisheries induced evolution
- Crecruitment variability
- Doverly-aggressive fish
20Examples of Fisheries-induced evolution include...
- Areduced size
- Bgrowth rates
- Creduced fecundity
- Dearlier age- and size-at-maturity
- Elater age-and size-at-maturity
- Fincreased size
21What is the maximum sustainable yield?
- ATheoretical
- Bmaximum yield that can be taken from specific fish stock over an indefinite period of time
- Cunder constant environmental conditions
- Dmaximum yield that can be taken from specific fish stock of a definite period of time
- Eprecautionary principle used to justify discretionary decisions
- Fprinciple used to quantify exact number of fish in the sea
22Invasive species:
- Aincrease competition and predation
- Bcreate trophic cascades
- Care usually great for the ecosystem
- Dare usually detrimental for the ecosystem
- Emodify ecosystem and habitat
- Fdecrease competition and predation
23Soft sediment is important because...
- Alargest habitat in the ocean
- Bhigh biodiversity
- Chighly productive
- Dlow biodiversity
- Elittle productivity
24Soft sediment restoration is mainly happening by
- Areducing fishing pressure
- Bincreasing fishing pressure
- Cstricter boating rules to reduce trawl damage
- Dlooser boating rules to increase trawl damage
25Trophic cascades occur in two directions: [blank_start]bottom-up[blank_end] (foundation species) and [blank_start]top-bottom[blank_end] (predator release).

- Btop-bottom
- Ctop-bottom
