The following efficient and quantitatively valid method to filter concentrate count live planktonic ciliates was developed compared with other treatments: unconcentrated (raw) samples centrifuged were counted live, the effects of five different fixatives (HgCl 2 , Lugol's iodine, formaldehyde, glutaraldehyde, Champy-DaFano) on counts monitored. Samples originated from a eutrophic mountain lake (Lake Aydat, near Clermont-Ferrand, France). Overall, filtered similar raw samples, but they...
The effects of prey size, hunger, and algal presence on the predation suspension-feeding calanoid copepod Acanthodiaptomus denticornis ciliates Tetrahymena corlisii (32 μm mean length), Paramecium aurelia (114 μm), P. caudatum (124 Loxodes sp. [Formula: see text], Stentor coeruleus[Formula: text] flagellate Astasia longa (14 μm) were evaluated in laboratory experiments. Adult consumed all species, but not proportion to their size. At low concentrations (prey < 200 μg C∙L −1 ), clearance...
Golfo Dulce is a deep tropical estuary whose ecosystem dynamics are poorly understood. In order to evaluate biomass and energy now distributions, productivity potential. obtain guidelines for conservation management, steady - state model of 20 compartments (excluding detritus) was constructed using the: ECOPATH II software. Total system (10.4 t/km2) total throughput (sum all flows, T = 1405 t/km2/year) small compared other modeled coastal ecosystems. The mayor pan the achieved from primarily...
Developments of bacterial and phytoplankton biomass were assessed during an annual sampling cycle in a eutrophic lake (Lake Aydat, France). Bacterial abundance, estimated by epifluorescence microscopy counting, varied from 0.61 to 12.72 × 10 6 cells/mL, confirming the status attributed this lake. Cellular densities nearly homogeneously distributed water column. Mean values for obtained three depths (2, 7, 14 m) 3.70, 4.23, 3.66 cells/mL. In epilimnion, productivity community composition, as...
Summary As agents of mortality, viruses and nanoflagellates impact on picoplankton populations. We examined the differences in interactions between these compartments two French Atlantic bays. Microbes, considered here as central actors planktonic food web, were first monitored seasonally Arcachon (2005) Marennes‐Oléron (2006) Their dynamics evaluated to categorize trophic periods using models Legendre Rassoulzadegan a reference framework. Microbial then compared through 48 h batch culture...
