The last section on this option before we find out how much you’ve learned.  REMINDER – test on THURS 1st MARCH on all of OPTION E.

Here’s what we need to cover in this last section of Option E.

  1. Honey bees are social organisms.  Describe the organization of a bee colony – who does what.  Find one other example of such social organization and describe it. Bio E6 Q1 bee pres
  2. What is the role of natural selection in colonies like this? alessandra_bianca_gio_natural selection   How natural selection may act at the level
  3. Give 2 non-human examples of altruistic behaviour and discuss in terms of evolution. E6 altruisitc examples
  4. What is foraging?  Bluegill fish forage for Daphnia.  Find one other example, and explain how this type of behaviour optimizes food intake. Foraging   Behavior- Foraging
  5. Peacocks have pretty fancy tail feathers.  Why have they evolved this way? Explain in terms of mate selection Group 5 Alisa Yurie Pratik.  Q5 Evolution of exagerrated traits
  6. Animals show rhythmical variations in activity.  Outline 2 examples illustrating this.  Eg, seasonal reproductive behaviour in deer. G6 Dan, Anna, Ashild Biology Powerpoint

Here’s a very useful slideshare presentation on this section.

E3 Innate and learned behaviour

Monday, February 6th, 2012

Can you distinguish between innate and learned behaviour?

What are some examples of behaviour in living organisms that are innate or learned?

What is taxis and what is kinesis when referring to types of behaviour?

You are then going to do a lab (yay!) where you design an experiment to investigate innate behaviour in invertebrates.  Lab sheet here: Invertebrate behaviour lab

You need to be able to analyse experimental data for these kinds of experiments in terms of the effect of this behaviour on chance of survival and reproduction (it all boils down to this – see Freud or Dawkins!).

Discuss how the process of learning can improve the chance of survival.

Outline Pavlov’s experiments into conditioning of dogs.  [Include conditioned and unconditioned stimuli and response]

Outline the role of inheritance and learning in the development of birdsong in young birds.

Here is a useful resource from Mr Taylor.

Here’s what we need to cover in this last section of Option E.

  1. Honey bees are social organisms.  Describe the organization of a bee colony – who does what.  Find one other example of such social organization and describe it. #1 2 Social Organisms
  2. What is the role of natural selection in colonies like this?
  3. Give 2 non-human examples of altruistic behaviour and discuss in terms of evolution.  Altruistic Behavior in animals
  4. What is foraging?  Bluegill fish forage for Daphnia.  Find one other example, and explain how this type of behaviour optimizes food intake. E6 notes #3 4
  5. Peacocks have pretty fancy tail feathers.  Why have they evolved this way? Explain in terms of mate selection. #5 animal behavior   Peacocks #5
  6. Animals show rhythmical variations in activity.  Outline 2 examples illustrating this.  Eg, seasonal reproductive behaviour in deer. Rythmical Variations

Here’s a very useful slideshare presentation on this section.

Behaviour

Tuesday, February 2nd, 2010

Here are some questions we need to answer:

  1. What is the difference between innate and learned behaviour?  How can the process of learning improve the chance of survival?  Give examples.
  2. What is the difference between taxis and kinesis?  Give examples of each.  How could these be investigated in the lab?
  3. What experiments did Pavlov carry out on dogs?  What is the difference between unconditioned and conditioned stimuli?  What is the difference between unconditioned and conditioned response?
  4. What role do genetics and learning play in the development of birdsong in young birds?

This presentation from Mr Taylor in Bandung is excellent, as is click4biology.

And we’ll finish this section by doing a design lab – you need to design an experiment to investigate innate behaviour by either taxis or kinesis.  This will just be a design exercise – we won’t actually carry out the lab. Here are the criteria: Design lab criteria
