Lotic -> movement in water (flowing water, streams) Lentic -> no movement in water (wetlands, ponds, lakes: evolution-evolutionary origins of many biota of lotic systems are different from those of marine systems which dominate the earth. Taxonomy-most straightforward basis of classification: major groups of organisms found in streams and rivers, microbes- fungi and bacteria associated with om and biofilm, lotic plants-macrophytes, mosses on rocks, filamentous algae. Invertebrates- larvae of insects, worms, various types of snails and bivalves, crustaceans: vertebrates- fish, plus amphibians, reptiles, birds, mammals, 3. Size: everything from microbes- unicellular algae-mosses-larger woolly macrophytes, animals-microbial protozoa-microcrustaceans, macro inverts to vertebrates (small fish to bigger things, 4. 10/09/2018: openness of the ecosystem-transport of dissolved and particular om from source to mouth. Inter-stream variability is high- each stream tends to differ from the next.
