A long term experiment storing 300 seeds from a species of plant and then at intervals of 5 years attempting to germinate 100 of these seeds to test for viability. Annual primary productivity in North American hot deserts is a function of precipitation. Determine the regression equations for the Mojave and Sonoran Deserts. On any date adult female I. Posita display considerable between individual variations in mass. There is even more variation between females collected early in the flight season and those collected later in the season.
Egg size seems to be associated with female size in an allometric fashion.
Make the appropriate transformation and determine the within date correlation of female size and egg size, as well as the between date correlation. Notonecta hoffmani goes through five instars during its development. Individuals from each instar were collected, marked and released at an aquatic habitat. A recapture sample was obtained. A graduate student was interested in determining if the bat community structure in Big Bend National Park is different today than it was approximately 15 years ago.
