Part 2: Content To Focus On

** In general, you should know all important key terms (mainly those that are bolded, but others as well) **

In addition to the key terms, here are some topics to focus on from each lecture:

Week 1 – Ecology & Biodiversity

Trophic levels (what types of organisms are found at each level – freshwater food chain example)

What is biodiversity? Know the different types of diversity

Limiting factors/law of tolerance

Measuring diversity (richness and evenness)

Levels of organization in nature

Week 2 – Species at Risk

COSEWIC/SARA acronyms, what are they, what is their function

COSSARO/ESA acronyms, what are they, what is their function

Eligibility Criteria to assess wildlife species

COSEWIC Process (3 steps)

Categories of Risk (COSEWIC)

Critical habitat

Week 3 – Invasive Species

What are native, non-native and invasive species?

Characteristics of invasive species

Common traits of invasive species

What can you do to limit introduction of invasive speciesReview video: Aquatic Invaders

Week 4 & 5 – Conservation Biology (pt. 1 and pt. 2)

What is Conservation Biology? What type of discipline is it, and what is the focus of the discipline?

Loggerhead shrike program – recovery strategies

Spotlight: WPC – who are they, what do they do, and what types of science-based techniques do they use?

Tools that conservation biologists use

Week 6 – Taxonomy and Classification

Main taxonomic ranks

Darwin’s principles of natural selection

variation is present

variation is heritable

individuals have different reproductive success

individuals with higher reproductive success leave disproportionately more offspring

and sexual selection

Competition for mates drives sexual selection.

Sexual selection can produce sexually dimorphic traits.

There are two forms of sexual selection:

a. intrasexual selection

b.intersexual selection

Mendel’s particulate model of inheritance

Hereditary information is transmitted from parents to offspring in the form of discreet “particles,” which we now refer to as genes.

Hardy and Weinberg’s work on population genetics

The frequencies of alleles in a population’s gene pool will remain constant indefinitely (i.e. will be in equilibrium) unless a “disturbing” influence is introduced.

A theoretical non-evolving population is said to be in Hardy- Weinberg equilibrium.

Binomial nomenclature

Two-word naming system

1. Genus: Noun, Capitalized,

Underlined or Italicized ?

2.Species: Descriptive, Lower Case, Underlined or Italicized

Dichotomous keys and example questions

Dichotomous keys versus evolutionary classification

Dichotomous keys contain pairs of contrasting descriptions.

After each description, the key directs the user to another pair of descriptions or identifies the organism.

Part 3: Sample Questions

Multiple Choice:

Ecosystem diversity, species diversity, genetic diversity all intertwine to create ______.

Vulnerability

Biodiversity

Interdependence

Recycling

Matching Definitions:

__B__ 1. Groups of organisms of the same species living in the same habitat A. COMMUNITY

__A__ 2. A group of populationsB. POPULATION

Short Answer:

List and describe the three steps in the COSEWIC process.

Candidate List selection of wildlife species requiring assessment

Status Report compilation of available data, knowledge and information

Assessment Results assessment of a wildlife species’ risk of extinction or extirpation and subsequent designation

Interpretation Question:

For this question, you may be given an image, a graph, or a diagram. You must interpret what is in the figure, and answers questions relating to it.
