摘要: Abstract We studied the effects of 6 green-tree retention levels and patterns on diets northern flying squirrels (Glaucomys sabrinus), Townsend's chipmunks (Tamias townsendii), Siskiyou (T. siskiyou), western red-backed voles (Myodes californicus), southern gapperi) using fecal pellet analysis. These rodents are truffle spore dispersers prey for forest predators such as spotted owl (Strix occidentalis caurina). Pretreatment showed differences in plant consumption among genera. Tree harvesting, especially 15% aggregated pattern, reduced frequency Rhizopogon spores diet voles, which may reflect a ability these animals to forage truffles, decreased access or reduction abundance frequency. Habitat island edge provide conceptual frameworks truffles by gr...
