b. How do monkeys establish dominance within a group?

c. How does pollution affect crop plants?

A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.
Spatial scales are interconnected in a hierarchical way. Whitman looked at invertebrate communities on subtidal rock walls to examine the relationship between local and regional species richness. His studies demonstrated that      A. local, not regional, processes determine local community species diversity   B. local species richness levels off at high regional species richness levels    C. local species richness is determined largely, but not completely, by regional species pools   D. local processes are unimportant in determine local community species diversity    E. There was no relationship between local and regional species richness
Examine the titles of the following sample journal articles. For each title, decide if you think the goal of the research is to: a.describe a cause-and-effect relationship b.describe a pattern, measurement, or observation in nature c.describe a scientific model d.describe a tool or process for scientific research e.something else   Journal article titles:  The impact of food and predation on the rise and fall of population sizes of snowshoe hare Two species competing for a limited resource cannot coexist How competition from other species and other factors affect where a barnacle species lives The interaction of drought and habitat explain patterns of where and when saguaro cactus plants grow Development of a new method for assessing the amount of disturbance in salt marsh ecosystems The make-up of the microbial community in the leaves of pitcher plants is affected more by the types of predators than the number of predator species.
