Endangered Species Laws Lacey Act Endangered Species Act Convention on International Trade in Endangered Species Be ready to compare/contrast I will answer only two questions from the class.
OK! Please put your natural selection reading outline on your desk for a stamp during the quiz!
Healthy? Threatened? Endangered? Counting has legal consequences! Please get out your wildlife management notes.
Random Sampling activity – (the beans) Share your * answers! #3 – Asymptotic point = more PRECISION #7 – How could we have improved accuracy? Does any of this apply to our lab work comparing the managed and unmanaged prairie areas?
Why count population size accurately? Census vs. Random sampling. Standardized procedure reduces bias Improving accuracy: More samples Strict standards for asymptotic point Tailor data collection to organism’s life history ROBUST DATA! Accuracy is important – legal protection can limit individual land use/decisions
Quadrant Sampling in Wolf Prairie – design flaws?
