Biology 263.3 Introduction to Population Biology 1997

(# Lectures)

(3) Introduction Population growth
- simple exponential and sigmoid growth models.

(3) Historical perspective - Darwin's theories of evolution.
The theory of Natural Selection.

(13) Population genetics - simple quantitative theory plus examples.
Hardy-Weinberg Principle - review
Mutation - how effect gene frequencies;
Variability - Classical and Balance hypotheses
Migration - gene flow, effect on gene frequencies Selection - gametic and zygotic single locus selection models, polygenic inheritance
Small populations - genetic drift and inbreeding
Combined effects of selection, mutation, migration and small popn size on gene freqs.
Evolution - The Modern Synthesis

(4) Population growth revisited - demography, the effects of age structure
Age specific death rates - survivorship curves and life tables
Age specific birth rates - net reproductive rate and population growth rate
Evolution of age specific birth and death rates - life history strategies

(4) Competition - intra and interspecific competition
Lotka-Volterra mathematical analysis
Selection and niche separation, effects on community structure

(4 ) Predation - Lotka-Volterra mathematical analysis, oscillations
Functional and numerical responses of predator and prey
Predator and prey behaviours

(6) Animal behaviour - genetic basis and evolution of behavioural traits
Problems - altruistic behaviour and kin selection; limits to aggression and game theory Reproduction - on choosing a mate, sexual selection
