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)
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
Darwins 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
Mendels 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 Weinbergs work on population genetics
The frequencies of alleles in a populations 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.
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
Ecosystem diversity, species diversity, genetic diversity all intertwine to create ______.
__B__ 1. Groups of organisms of the same species living in the same habitat A. COMMUNITY
__A__ 2. A group of populationsB. POPULATION
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
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.
