01 Apr, 12 AM - 30 Apr, 10 AM

The goal of this project is to explore linkages between the spatial distribution of alders in the SFE River watershed, foliar and phloem quality (C:N:P), terrestrial herbivore performance, and in-stream respiration and decomposition. Green leaves from individual trees, as well as phloem and associated invertebrates will be collected periodically throughout the study and analyzed for carbon, nitrogen and phosphorus content. These samples will be collected from numerous locations throughout the reserve, spanning a wide range of drainage areas, and thus light and temperature gradients. Sites will include upper and lower Elder, Ten Mile, Jack O'Hearts, and multiple sites on the South Fork Eel (Jack O'Hearts, Jane's Riffle, Globi and Ten Mile). Leaf litter will also be collected during the fall and winter months, and in-stream rates of mass-loss, microbial respiration and invertebrate colonization will be measured at each of the study sites. During this part of the study, litter bags will be incubated in the various streams, and a common garden experiment containing litter bags with leaves from all sites will be conducted at Lower Elder. From leaf-out (March) through September, green leaves, phloem, and invertebrates will be collected periodically, and individual alders may be fertilized with nitrogen and phosphorus to assess the affect of nutrient availablility on invertebrate performance across the gradient in drainage area.
