Linkages between trophic variability and distribution of Pteronarcys spp. (Plecoptera: Pteronarcyidae) along a stream continuum
|
ABSTRACT.-Pteronarcys stoneflies, which are traditionally considered shredders in eastern North America, inhabit second- through seventh-order streams in the Little Tennessee River (LTR) drainage basin. Because very little coarse allochthonous particulate organic matter occurs in the relatively large (sixth- and seventh-order) LTR, we analyzed the gut contents of five individuals from each of five sites and two dates (August and December) (n = 50) along a fourth- through seventh-order stretch...

Hydrologic and terrain variables to aid strategic location of riparian buffers.
Journal of Soil and Water Conservation
; One of the promising land-use practices hypothesized to mitigate non-point source pollution is the vegetated riparian buffer. Buffers are viewed as a solution to water quality problems associated with agricultural production systems where they are located at the edge of fields adjacent to streams.
