How does form fit function and how it helps fit the species ability to survive in the environment -Physiology- how much food and water does it need to survive grow reproduce? How vulnerable is it to extremes of climates? When and special requirements for reproduction? How many offspring produced? -Genetics-How much variation exists? How much variation exists in individuals and within populations? -Environment- Where are the species found and what are the habitat types? How variable is the environment?

How have humans altered the relationships among species in the community? -Demography- What are the current population size and the effective population size and what where they in the past? *effective population size- the number of breeding individuals in a population- often smaller than the total population size- Ne -Behavior-How do the actions of the individual help it survive? How do they mate and produce offspring? -Interactions with humans- How do human actions impact the species? Do people harvest or use the species in any way? What do locals know about the species? Monitoring Populations in the field -fieldwork is the best resource and way to examine a species -census studies are used to monitor the conservation status of a species -Monitoring Studies are also done such as in the case of butterflies a sensitive species- most common ways are inventories, surveys, and population demographic studies. -inventory- a count of the number of individuals present in a population. Inexpensive and straightforward. -survey- involves using a repeatable sampling method to estimate the number of
