Angelo Coast Range Reserve

18 Apr, 05 AM - 30 Apr, 09 AM

We will assess the interacting effects of food resources and thermal conditions on growth and development of tadpoles and recruitment of juveniles to frog populations. We will evalute the relative contribution of sites that vary in quality with respect to resources and conditions. Given that tadpole growth varies with water temperature as well as the quantity and quality of algae,and that tadpoles are generally protein limited we will test the assumption that habitat with suitable physical conditions (i.e. depth, velocity, and temperature) also has high resource value. We will compare tadpole growth rates across sites varying in temperature and primary production, conduct nutritional analyses of the algae tadpoles are consuming in relation to thermal environment, as well as investigate the effects of temperature on predator prey interactions. We also plan to test the utility of stable isotope analyses as a tool for evaluating habitat quality. The work in the unregulated South Fork Eel River and Ten Mile Creek provides an important natural reference state for comparison to rivers with hydroelectric dams that have altered hydrologic and thermal regimes.
