“…Overhanging vegetation has been shown to be important for the hiding of burrow entrances . It seems reasonable to assume that some of these 'riparian' differences, coupled with the 'in-stream' differences, would be associated with changes in in-stream food availability for the platypus and Davies et al (2005b) found an overall reduction in macroinvertebrate biomass in the logged streams. Serena et al (2001), however, suggested that platypus may select optimal foraging areas based not only on prey availability, but also on the amount of time and effort required to detect, capture and consume food items.…”

This study examined the occurrence, relative abundance and condition of platypuses in the upper catchment of the South Esk River, in north-east Tasmania, Australia, and the impact of past forestry activities on the occurrence of platypuses in first order headwater streams. The main trapping sites were in twenty first order streams, eight second-fourth order headwater streams and one fifth order stream reach. Additional trapping was also undertaken in the South Esk River and farm dams. Sites were trapped during late spring/mid summer and early autumn. A total of 78 individuals were caught in the study area. Platypuses were caught at all sites trapped in the second-fourth order and fifth order stream reaches and in nine of the twenty first order streams. Catch success was greatest in the fifth order stream reach and lowest in the first order streams. There was a trend toward a higher proportion of juvenile/subadult males in the lower order stream sites. For the higher stream orders, a higher proportion of individuals was caught during the summer, however for the first order streams, a higher proportion was caught during the autumn trapping period.Information collected on the body mass, body length and condition of individuals indicated smaller individuals with a higher tail fat index in the lower order streams.There was a trend toward a lower occurrence of platypuses in the first order streams, which had been disturbed 15 years previously by forestry operations compared to first order streams with relatively undisturbed catchments. Differences in occurrence of platypuses were related to differences in the 'instream' and riparian characteristics of disturbed streams compared to undisturbed streams. Headwater streams form a large proportion of a river system. Although they provide more marginal habitat for the platypus than larger river reaches, their disturbance may be an important land management issue in the conservation of this species, particularly in river catchments where the species is impacted by other environmental changes or disease.

“…This is mainly due to enormous environmental factors which could influence FFG composition. In addition to those factors reflecting the position along the longitudinal gradient (e.g., altitude, distance from source, stream order, and channel width), these included riparian vegetation (determinative to shredders) (Cummins et al, 1989;Davies et al, 2005;Lecerf et al, 2005), fertilizer runoff (Delong and Brusven, 1998), food quantity and quality (Peeters et al, 2004;De Lange et al, 2005), presence of fish (Trigal et al, 2007) and human activities (agriculture, forestry, urbanization, etc.) (Larranaga et al, 2006).…”

“…Removal of overhead canopy could influence the increase biomass, density and seasonal production of benthic macroinvertebrates (Behmer & Hawkins 1986). Logging can change the amount and type of particular organic matter (Davies et al 2005). One of the major consequences of clear-cut logging is the change in the energy base of stream systems (Kedzierski & Smock 2001).…”

“…The connection among factors operating at different spatial scales and their distinct influence on a stream ecosystem function is a very important environmental topic (Davies et al 2005;Schiller et al 2008). This paper demonstrates historical influences of landscape on quantitative variables and a special group of hyporheos in the two fifth-order streams of similar origin, but different catchment landscapes and forest management.…”

Abstract:The historical influence of landscape on the quantitative variables and a special group of hyporheos in streams with similar origin but different catchment landscapes and forest management was studied. The study was conducted in two streams: (i) a preserved forested natural stream where critical ecosystem processes were unaltered by human activities and (ii) a stream with the strong anthropogenic stressors (e.g., logging, agriculture, pasture), impacting the system for the last 500 years. Some parameters were strongly related to these land use: conductivity, fine benthic organic matter (FBOM), orthophosphate (P PO4) and periphyton content all increased along the gradient from the natural stream to the urban-dominated catchment. The density of interstitial assemblages corresponded with the conductivity (at P < 0.05) and was higher on the stream in urban-dominated catchments; and the Harpacticoida taxa richness, dominated by the family Canthocamptidae, was also greater here. The Multiple Regression Analysis shows that the rate of deforestation had had the most significant effect on the density of hyporheos. Among of crustacean fauna the representatives of epigean harpacticoids from (of) family Canthocamptidae, dominated.
