Angelo Coast Range Reserve

30 May, 09 AM - 30 Jun, 09 AM

We propose to conduct three studies in 2010-2011. 1) Evaluate the consequences of different predator assemblages and the importance of terrestrial subsidies for young of the year (YOY) steelhead growth and survival. These data will allow us a better understanding of the food web structure of tributary streams where a large number of juvenile steelhead rear before migrating to the ocean. 2) Trace the sources of energy and resources used by juvenile steelhead and Dicamptodon salamanders across the S. Fk. Eel watershed. These data will be used in combination with previous studies at the Angelo Reserve to better understand the spatial patterns of energy flow and food web structure across the strong downstream gradients (physical, chemical, biological) present in watersheds. 3) Estimate the population size, structure, and demographic rates of Dicamptodon populations in the presence and absence of steelhead. These data will be used in combination with data from the literature to parameterize a series of population dynamics models to evaluate how the overlap between Dicamptodon and steelhead affect the population size and persistence of salamander populations in tributaries.
