Concept Maps Visual road maps that depict known or suggested relationships between ideas. Idea/info relationship Idea/info examples For example Dairy products typically represents ideas and information as boxes or circles, which it connects with labeled arrows Meat/Fish REQUIRE CAUSE CONTRIBUTES Fruits/Veges

Concept Maps can help you: You have a broad interest 1. Hone in on your scientific question 2. Provide context for your scientific question, and organize and structure your Introduction 3. Develop hypotheses to test 4. Determine methodology required to test hypotheses You need a question You have a question You need broad context

AMAZONIAN RAINFORESTS 1. Honing in on your scientific question Birds AMAZONIAN RAINFORESTS HABITAT critical to give Arthropods AMAZONIAN RAINFOREST Mammals ? +/- Olinguito !!! such as

2. Honing in on your scientific question (another approach) Arctic tundra is becoming Shrubbier! Arctic tundra is becoming shrubbier! + - Missing grey arrows of relationships other people didn’t even think about! ??? (taken from Myers-Smith et al. 2011)

Who cares ? 2. Providing context for your scientific question (for your Introduction) Does the presence of caribou inhibit/promote shrub dominance in Arctic tundra? Question on a silver platter or you happen to have one Why on EARTH should any body care You need broader context to justify your study, but also to provide relevant background information. Who cares ? (start reading!)

Does the presence of caribou inhibit/promote Arctic climate warming fast Abiotic & biotic responses are acute thermokarst fire regimes growing season length veg productivity woody shrub dominance energy balance carbon sink/source alters wildlife habitat nutrient cycling thaw depth snow distribution for example causing Feeds back to Climate Forcing! Caribou are the main large herbivore in northern Alaska Trample Forage Fertilize impacts +/- ? contribute to which impacts Does the presence of caribou inhibit/promote shrub dominance in Arctic tundra?

3. Development of Hypotheses +/- ? Shrub dominance understory vegetation damage shrub branches Increase nutrient availability for all species fertilize shrub species forage understory 4. Determine Methods
