what are the most important “fixes” in energy consumption
Exam 3 Review 1 Readings and Lectures As you prepare for quizzes and tests, I strongly recommend reviewing your lecture notes and slides, reading the assigned chapters in Campbell and using the chapter reviews in your text. Be prepared to define any terms we have covered. You may bring a 3 x 5 handwritten notecard to the exam. Community Ecology/Interactions ‐ Ch. 37 & Lecture notes
o Define niche; habitat o interactions w/in communities:
pred‐prey features of each; benefits to both defensive coloration; mimicry
competition: interference; exploitative niche theory;
o competitive exclusion (Gause) o resource partitioning
what is primary(1o ) productivity? What abiotic factors most likely to influence rates of 1o production?
Serengeti Plains: wet & dry seasons; migrating herbivores; different food & timing (establish a niche)
What determines population sizes for: Predators? Herbivores?
review the story…; how specialized niches reduce competition Africa: The Serengeti (the movie) ARTICLE: The Serengeti ‐ An Herbivore Dominated Ecosystem
Symbioses = ?? (define): parasitism (endo and ecto); commensalism; mutualism Coevolution – definition & examples Mutualism / obligate mutualism – definition & examples Detailed case studies (review adaptations / evidence of coevolution):
o flowering plants and pollinators; Acacia trees and Acacia ants Conservation Biology (Lecture & Ch. 38) what is the biodiversity crisis?
what are 3 main causes? and examples of each endemics; hot spots
why worry about loss of biodiversity? how do we know if a species is in trouble? = must understand habitat requirements fragmentation of habitats and populations (effect on genetic diversity)
how does it hurt a species with small populations? what are edges?
Red‐cockaded woodpecker Northern spotted owl – why so controversial? conflicting demands = human needs vs. biological and ecological needs of other species Nature reserves
Costa Rica’s zoned reserves buffer zones sustainable development
main goals of conservation biology long‐term maintenance of ecosystems reduction in rate of extinctions sustaining ecosystems diversity: genetic and ecosystem understanding human needs

Exam 3 Review 2 Energy, Air & Climate Change (Lecture & Ch. 38) low energy vs. high energy societies shifting energy dependency: wood to coal to oil/natural gas Fossil Fuels: what are they, how were they formed?
disadvantages of fossil fuels non‐renewable vs. renewable resources energy consumption by source alternative energy sources: know advantage and disadvantage of each what are the most important “fixes” in energy consumption? (conservation & renewables) “Before the Flood” the movie
greenhouse gases how have humans increased greenhouse gases? global warming/climate change:
what is it? what are the consequences of global warming?
What can we do? reduce waste reduce consumption reduce pollution modify lifestyle: consume differently get involved: leaders to fight climate change
