How many species are there? Determining species richness
One of the simplest questions an ecologist can ask about a site is how many species live there. The answer is important for basic researchers and managers alike, but can be deceptively hard to obtain. This exercise introduces students to the issues surrounding the estimation of species richness, and can be completed in a single three-hour lab session. Students will learn to collect data in the...

Patterns and process in Landscape Ecology: Physical template, biotic interactions, and disturbance regime
Ecological processes and patterns interact at various scales across landscapes. Spatially explicit consideration of pattern and process can better inform ecological questions. This Figure Set introduces students to the variability in scales of pattern and process and to the fundamentals of Landscape Ecology. TIEE

Simulating Sampling Communities and Calculating Diversity Indices with Scrabble Game Tiles
Using tiles from a Scrabble game, we present methods to create simulations of sampling exercises and to develop diversity indices. The tiles represent species, and so a known sampling universe (100 tiles) allows comparing a sample with the known distribution of species. We then offer several variations to simulate different kinds of sampling (larger sample size, more samples), alter the rarity...

Case Study on Mark and Recapture
Estimating the population size of animals is an important task for wildlife biologists, who can use the data to assess the health of a population. It requires diligent observation skills coupled with the ability to use empirical models that effectively determine the number of animals based on field surveys. The most common method for estimating the population size of animals is mark and recapture....
