Q

Primary Focus of Marine Conservation Biology

A

• Conserve components of biodiversity
Unit 1: Defining Marine Conservation Biology
– Genetic, Species, Ecosystem Diversity
• Not just economic value but also to ensure use
is sustainable

Q

Early Man

A

Profound influences since early time
(controversial for Pleistocene megafaunal extinction
event although 80% of N. American large mammals
disappeared within 1000 years of human arrival)

Q

Early Man

A

• Very little evidence of early or primitive
conservation effort
• Pattern of exploitation and land use:
– Use it and move on to another source
• Interacts with environment to maximize its use
– Widespread use of fire to clear land by early people

Q

Early man

A

‘Conservation’ without restraint and
cost is not real conservation
• Most environmental interactions by early man do
not fit this mold despite many efforts to paint a
picture of ‘noble primitive peoples’
• One potential early aquatic e

parent organization of WWF

18
Q

Michael Soulé

A

1978 First International Conference

on Conservation Biology.Led to creation of SCB

19
Q

Smalles ecological scale. Type 1

20
Q

smallest ecological scale Type 2

A

Biotic

  1. Intraspecific
  2. Inerspecific
21
Q

population

A

A group of organisms that interbreed & live in
the same place &
time

22
Q

Metapopulation

A

A group of spatially
separated populations that
interact at some level

23
Q

Community

A

A group of species interacting in the same place

24
Q

Ecosystem

A

All biotic and abiotic factors in an area

functioning as a unit

25
Biome
A major ecological community adapted to a | particular climate or condition on a large scale
26
Internal fertilization
Many gastropods, most crustaceans, all Chondrichthyes, few bony fish. complex mating behavior
27
Broadcast Spawning
Both eggs & Sperm e.g. | » Most bony fishes, echinoderms
28
Sperm only
» Sponges, cnidarians, mollusks, ascidians
29
Allee Effect
• Term used when population reduction leads to reduced reproduction.Reduction in mating success with declining density (W.C. Allee, 1931). Opposite? – Greater population size increases PER CAPITA population growth
30
Component Allee Effect
Positive relationship between specific fitness component • # matings, # seeds, offspring survival etc trphy hunting, ecotorism, exoctic pets
31
Demographic Allee Effect
Positive relationship between OVERALL fitness and population size and therefore per capita population growth rate and population size. Most worrisome
32
Multiple Allee Effects
Very common in east coast marshes, dense aggregations – Low density populations suffer from increased mortality from crab predation & ice
33
Anthropogenic Marine Allee Effects
Rare species considered more valuable suffer enhanced exploitation and become more rare
34
Life history traits
Reproduction – Dispersal patterns – Variable habitat us
35
Two major factors that influence | dispersal in marine organisms:
``` – Larval dispersal • Influenced by spawning method – Adult vagility • Swimming • Rafting ```
36
General Human Conditions
poverty, ignorance, affluence,indifference, technology
