Changes in the structure of benthic insect communities at an experimental site and at a reference site in the Ford River, Michigan were monitored over a 10-year period to determine whether extremely low frequency electromagnetic fields (ELF) affected

SUMMARY 1. Forest stream food webs depend largely on input of dead riparian zone leaves for their energy, which is converted into living biomass by microbes, macroinvertebrates and fish. 2. Temperature has been invoked as important in controlling bre

Movement patterns of dragonfly naiads in a small northern Michigan stream were followed from 1985 through 1989 to determine if Extremely Low Frequency (ELF) electromagnetic fields affected movements for this predator. ELF lines were activated in 1986

SUMMARY. 1 Communities of invertebrates colonizing senescent autumn and fresh summer alder leaves (Alnus rugosa) were compared. Leaf packs for each treatment were placed in two hardwater streams in the Upper Peninsula of Michigan in late summer and e

Lotic ecologists share a major goal of explaining the distribution and abundance of biota in the world's rivers and streams, and of predicting how this biota will respond to change in fluvial ecosystems. We discuss five areas of research that would c

Heavy runoff from watersheds affects lowland streams in two general ways. Either a stream experiences spates (increased forward velocity and scouring of stream bottoms) or it becomes inundated by waters from larger rivers, causing the stream to be ba

The relative abundances and distribution patterns for two species of aquatic predaceous creeping water bugs (Family: Naucoridae) were determined for two tropical streams at Finca La Selva, Costa Rica, from July 1975 to August 1977. Seasonal changes i

A chironomid, Brillia flavifrons Johannsen (Orthocladinii) previously thought to specialize on decaying wood, consumed Tag Alder leaves (Alnus rugosa (Du Roy)) in two Michigan streams, Schwartz Creek and the Ford River. Schwartz Creek's substrate is

Differences in the dynamics of allochthonous leaf processing in tropical streams are compared with those at mid-latitudes. Phytochemical differences are linked with transferral of energy in stream ecosystems. Condensed tannins, defensive secondary co
