Q

Describe conservation behaviour (combined).

A

-Application of knowledge of animal behaviour to solve conservation and management issues
-Relatively young, but growing field
-Focuses on conservation and management of a single species
-Use of well-designed experiments to collect data on factors important to conservation

Q

What are conservation efforts like for marine species?

A

Poor, with exception of cetaceans
-Received less attention than conservation of terrestrial species

Q

What is a leading branch of applied ecology?

A

-Fisheries research
-Largely based on life tables
-research on behaviour largely avoided to simplify analyses

Q

What are the two potential links to conservation that behaviour might have?

A

-May affect the vulnerability of organisms to being killed or having some aspect of their life cycles disrupted (eg foraging behaviour
-Behaviour may play a key role in translating individual mortality into population changes (density dependent changes in reproductive behaviour may affects rates of population growth)

Q

How can shoaling be exploited by the fishing industry?

A

-Entire shoals and spawning aggregations can be surrounded by nets
-High catchability may cause problems for accurate stock assessment
-Can yield profitable catches even when total population sizes are low
-May hasten species decline
