Abstract
Transport and availability of various size fractions of organic material along with bottom structure and benthic invertebrates, grouped with respect to feeding types, were examined along an 8 km long stream in southern Sweden. Transport of coarse particulate organic material (CPOM) was insignificant, while considerable amounts of fine particulate (FPOM) and dissolved organic matter (DOM) were carried downstream. DOM showed little variation and was constantly 2-3 times the energy of suspended FPOM. Export of DOM was 5 times as high as that of FPOM, total organic output being twice as high as leaf [from beech, alder, oak, etc.] input. On a stony bottom shredders and scrapers dominated, while scrapers, deposit feeders and filter feeders were abundant where sedimentation was heavy. Downstream the section with most extensive sedimentation all categories including predators were well represented.This publication has 4 references indexed in Scilit:
