Connectivity Flashcards
What are different categories of connectivity?
1) Structural
2) Functional
3) Realized
Structural connectivity
Physical attributes of seascape
Functional connectivity
Information on individual’s dispersion or migration capacity
Includes information on life dynamics
Realized connectivity
Patterns derived from empirical data, via observation, tracking or tagging data
Why are nursery areas located in protected areas?
Favorable for development and survival
1) food availability
2) higher temperatures
3) Refuge from predators
What is recruitment?
When juvenile/sub-adult individuals join adult population
Why do fish move to feeding areas?
Higher food availability
What characterizes spawning areas?
Closer to the coast and are favorable for larval dispersal
Why is it important to study connectivity?
1) Identification of ecologically important habitats
2) Sustainable management of fish populations
3) Design of marine protected areas
How to estimate connectivity and movement amoung fish populations?
1) Abundance, distribution and length structure
2) Artifcial markers
3) Natural markers
4) Bio-physical markers (only for larvae and eggs)
