Ecological and Environmental Sampling

taught by Bryan Manly

Aim of Course:

This online course, "Ecological and Environmental Sampling" covers sampling methods and analyses used to study the density and abundance of animals and plants, and other important biological variables. It starts with classic random sampling methods and their extensions (systematic sampling, stratified sampling and more), and goes on to cover methods (such as adaptive sampling, mark recapture, line transects, and more) that have particular applicability to estimating population sizes. The theoretical basis behind methods is discussed, but the emphasis of the course is on understanding how to use methods effectively rather than the derivation of the equations used.

Course Program:

WEEK 1: Standard Survey Sampling Methods

  • Introduction to ecological sampling methods
  • Simple random sampling for the estimation of population means, totals and proportions
  • Stratified sampling
  • Systematic sampling
  • Other specialized sampling strategies

WEEK 2: Other Specialized Sampling Methods

  • Adaptive sampling methods
  • Line transect sampling
  • Removal and change in ratio methods

WEEK 3: Plotless Sampling and Mark-Recapture Methods

  • T-square, wandering-quarter and related sampling methods
  • Closed population methods
  • introduction to methods for open populations

WEEK 4: Occupancy Models, Environmental Monitoring and Trend Analyses

  • Occupancy
  • Environmental monitoring designs
  • Models for trend analyses


Homework in this course consists of short answer questions to test concepts, guided data analysis problems using software, and guided data modeling problems using software.

In addition to assigned readings, this course also has Discussion tasks.
