Spatio-temporal variation of periphyton biomass and accumulation in a temperate spring-fed stream

Abstract: Spatio-temporal variation of plant populations often can demonstrate synchronous patterns, particularly within highly connected landscapes. Periphyton biomass (chlorophyll a) and net accumulation were measured at five sites in a spring-fed fourth-order stream located in central Pennsylvania with a mixed land-uses watershed (Spring Creek, USA) to characterize longitudinal variation within the stream. Samples were collected at three-week intervals over one year to describe seasonal patterns of periphyton biomass… Show more

“…3,5;Tables 3,6). Average biomass in urban streams of 18.8 ± 6.0 g/m 2 AFDM and 75.6 ± 28.5 mg/m 2 Chla, and maximal Chl-a levels exceeding 100 mg/m 2 , are comparable to quantities measured in agricultural streams elsewhere (Biggs & Close, 1989;Chételat et al, 1999;Godwin & Carrick, 2008) and in experimentally nutrient-enriched streams (e.g., Greenwood & Rosemond, 2005). However, variation in stream algal biomass in our study area was not correlated with % agricultural land, despite dominating the watersheds of 13 streams.…”

“…Sampling locations were selected to reflect changes in land use, stream morphology, and geology within the watershed (see Godwin & Carrick, 2008). Sites 1 and 2 were located in Galbraith Gap Run on the ridge and sites 3, 4, and 5 were located in the valley, within the main channel of Spring Creek.…”

“…Although periphyta make up only a minor component of the total ecosystem carbon budget, they are vitally important for maintaining secondary production in streams (Mayer and Likens, 1987;Hall et al, 2001;McCutchan and Lewis, 2002). Second, periphyta play a key role in nutrient cycling in stream ecosystems through nutrient uptake, transfer of nutrients to higher trophic levels, and remineralisation (Schiller et al, 2007), so they are integral in biogeochemical cycling (Godwin and Carrick, 2008). Moreover, primary producers are important mediators of anthropogenic impacts in almost all ecosystems .…”
