Subject Outline
Focus on mammals
 64,000 pubs in 2013
 67,000 pubs in 2014
Subject Outline
Knowledge of
• Structure, function, and development of the
reproductive organs (Male & Female);
• Endocrine and neuroendocrine and environmental
control of
– reproduction,
– mating,
– fertilisation,
– pregnancy,
– parturition and
– lactation in vertebrates; and
• Human intervention in the reproductive process
• Common human reproductive diseases and disorders
Subject Outline
• Generic skills:
– Attain knowledge from lectures, tutorials,
observation and the literature
– use that knowledge to evaluate and communicate
results
– access information in primary scientific literature
– abilities to evaluate scientific evidence critically
– skills in data interpretation, and identifying
alternative explanations
• We will assess your understanding – note
learning is not enough.
• Lectures- Mon, Tues, Weds, Fri
– but Friday lec. slot mainly for tutes
(may run impromptu tutes in the extra slots)
Lecture: should NOT be “the process by which
the notes of the lecturer become the notes of the
student without passing through the mind of
either”
Focus on what is being said; ask questions…
• Tutorials
– quizzes
– structured learning exercises
– raise questions on lecture content
• Assessment
– 35% Seven online quizzes
– 15% Literature review
– 10% 50 minute mid-semester test
– 40% end of semester exam
Electronic Communication
• Notices in the Announcements area in LMS
• Emails (we will use your University of Melbourne
email address)
• Electronic forums/discussion boards on LMS (feel
free to contribute to these)
• Direct to us on
BIOL30001@zoology.unimelb.edu.au
Check all of these regularly!
Feedback
• Continuous assessment (e.g. online quizzes
and mid-semester test)
• Lecture-time, tutes, quizzes & lit review
assignment
• Seek us out at other times (but forgive us if we
are busy)

TIME: don’t rely on swotvac
• Don’t pretend that doing nothing in term
then cramming for hours in swot vac is
enough.
• This is a subject with a large amount of
content, which is why we encourage you

Why Study Reproduction?
•
•
•
•
•
Fundamental to life
Farming
Fascinating
Fun
Future of human civilization
Patterns of reproduction
• Asexual
• Sexual
Asexual
• fission
• budding
• parthenogenesis
hydra
aphids
whiptail skink
• no exchange of genetic information - clonal
Sexual
• Exchange of genetic information
• bacteria etc.
• 2 sexes – female / male + …?
sperm
• female – eggs – large  embryo
• male – sperm – small, motile
• meiosis vs mitosis
fertilised wallaby egg
0.1 mm
Variations on a theme
protogyny
• Hermaphrodites
protandry
• Parthenogenesis
Question:
• what selective pressures may favour
evolution of protandry vs protogyny?
Sex and the echiuroid worm Bonellia
Echiuroid worm - Bonellia
• Female worm is rock dwelling
• Male lives inside the female’s uterus &
fertilizes her eggs
• If larva lands on sea floor becomes
female
• If larva lands on the proboscis of a
female - chemical attractants emitted
• Larva will enter females mouth, migrate
to the uterus and differentiate into a
male
