Toad Data Gathering Part 1

Toad Data Gathering Part 1

Our research and driving question is (fix text size) “How does the amount of rainfall affect the population dynamics of the California Toad (Anaxyrus boreas halophilus) in the Southwestern San Gabriel Mountains?”

So far we have been using a belt transect method to gather data on the tadpole life cycle stage of the toad.
We are going to compare every year the population density of the tadpoles and toads with the amount of rainfall located at two main breeding sites.

We hypothesize the increased rainfall will increase the chances of the tadpoles surviving and increase (I suggest using a different word as the use of “increased” is redundant) the overall adult population of which we will also gather data on by using a transect sampling and direct observations during the breeding season. Using historical data donated by herpetology associations consisting of professional and amateur herpetologists, we can compare our first years data to previous years and see if there is a trend depending on the amount of rainfall and determine if there are any correlations of population size and amount of rainfall.

Our current freshman and sophomore volunteers will gather data every year until they graduate and any incoming freshman who want to pursue science at the university level are more than welcome to participate in this longitudinal study.
