Define Animal Behaviour
mechanisms and functions of a behaviour
1 of 15
Define Behavioural Ecology
how physical environment impacts on an animals behaviour and its evolution
2 of 15
Define Sociobiology
how social environment impacts on an animals behaviour and its evolution
3 of 15
What four questions do we ask when looking at behaviour?
1) Mechanism: what and how? 2) Survival Value 3) Evolutionary 4) Developmental?
4 of 15
5 Steps Of Natural Selection
1) Variation 2) Competition 3) Sucess/Fitness 4) Inheritence 5) Adaptation
5 of 15
What are the two types of behaviour?
Innate and Learned
6 of 15
Describe innate behaviour.
genetically programmed response to stimuli, heritable, intrinsic, inflexible, No learning required
7 of 15
Describe learned behaviour.
as a result of experience, non hereditable, extrinsic (not in wild would effect behaviour), can change, adaptive
8 of 15
Outline 5 types of learning.
1) Habituation 2)Observational 3)Conditional 4)Learning Through Play 5)Insight Learning
9 of 15
Describe Imprinting.
Programmed learning, innate behaviour released in response to a learnt stimulus, critical period
10 of 15
How did learning evolve?
assumed some cost to learning, ability to learn will be favoured in environements that change relatively often
11 of 15
What is a FAP?
Fixed Action Patterns, sequence of unlearned behavioural acts, unique, unchanging, once initiate carried out to complettion e.g. stickleback fishey
12 of 15
What is direct and indirect fitness?
direct= own offspring, indirect fitness= helping relatives
13 of 15
What is Hamilton's Rule?
rB>C, r=coefficient relatedness B= benefit gained by recipient, C=cost individual performing act
14 of 15
Define Alturism
Fitness of another individual at a cost to yourself
