introduction to behavioural and evolutionary ecology

what is behavioural and evolutionary ecology?
the survival value of behaviour- how behaviours contribute to an animals survival and therefore reproductive success
1 of 12
what are Tinbergens 4 why's?
function-what's it for? mechanism-how is the behaviour achieved? development-how is it developed? evolution-where has the behaviour come from?
2 of 12
what's an ultimate factor?
behaviour that is for survival
3 of 12
what's a proximate factor?
what causes the bahviour
4 of 12
can behaviour be influenced by natural selection?
ns only works on genetic variation. for a behaviour to evolve 3 conditions must be met
5 of 12
what are the 3 conditions needed for natural selection to occur?
variation, inheritance, competition

what does Paley (1802) say regarding a watchmaker?
the complexity of living organisms is evidence of the existence of a divine creator- an intelligent watch maker
7 of 12
what does Dawkins (1986) say in response to Paley?
the only watchmaker in nature is the blind force of physics, albeit deployed in a very special way... it's the blind watchmaker
8 of 12
what are the 3 studies used to show evidence that genes affect behaviour?
creation of mutants, artificial selection and population studies
9 of 12
what was the study done by (Benzer, 1973)?
creation of mutants- using wild type and mutant drosophilia. the licking and vibration was performed less in the mutant species, meaning they were unable to reproduce
10 of 12
what was the study done by (Manning, 1961)?
artificial selection. breed for behaviours regarding drosophilia mating speeds-selection experiments produced fast and slow strains. cross breeding unsuccessful
11 of 12
what was the study done by (Arnold, 1981)?
population studies. used two pops. of garter snakes. coastal species like slugs however the inland (freshwater lakes) don't. they avoid slugs as they resemble leeches which are toxic.
