BIOL 214: Study Guide for Lectures 1 & 2 *** This study guide is NOT all-inclusive, you are still responsible for the material covered in class and on the homework, even if it does not appear here *** Key Terms & Concepts you should understand and be able to define and explain • Gene, locus, allele • The two levels of ecology: - Microecology - Macroecology • Evolution / Fitness / Natural Selection – definitions of and distinctions in the meaning of these terms- (e.g., evolution is not a synonym for n.s.) • Pattern / Process / Model – what each is, how they differ, how each contributes to scientific understanding • Observation • Formulating and testing hypotheses • Definition and distinction between theory and hypothesis • Different types of hypothesis testing: - manipulative experiments - natural experiments - observational studies • Ecology • Ecological patterns of distribution • Organism and Environment interactions • Thermal Performance curve (TPC; Huey and Stevenson) and their variations • Portner Model – Oxygen and Capacity-Limited Thermal Tolerance (OCLT) • Coupled Heat/mass balance equation - what is the overall concept here- (not necessarily focusing on memorizing the individual terms) Sketch the following to improve your understanding of the concepts: Thermal Performance Curve -- variation in TPCs – describe parametric ways in which TPCs can evolve and their implications; also be able to describe the ways in which TPCs are stereotypic. Shelford’s Law of Tolerance as it relates to patterns of distribution Highlighted studies: Examples to connect key terms and concepts to real-world science applications Tracy 1975, organisms and their environment Dunham et al. 1989 “Summary of constraints on an ectotherm’s behavior” figure Huey and Stevenson 1979 TPC Portner Model: OCLT figure Thought questions: Reflect and recall in detail a key concept we covered this week. • Are theory and hypothesis synonyms? Why or why not? Recall what each of these mean in the scientific context and explain how they are properly used. • The CVH was originally proposed by Janzen to explain differences between the temperate zone versus the tropics. However, in principle the hypothesized cause of selection can operate anywhere. In which parts of the world might we expect to find eurytolerant versus stenotolerant species? – deep oceans; the intertidal; high mountaintops; deserts; arctic/ Antarctic; a large deep lake like the Great lakes; a small shallower lake; a cave;BIOL 214: Study Guide for Lectures 1 & 2 *** This study guide is NOT all-inclusive, you are still responsible for the material covered in class and on the homework, even if it does not appear here
