Benthos Composition and Abundance in Lentic Ecosystems

Recovery in Antarctic benthos after iceberg disturbance: trends in benthic composition, abundance and growth forms

The response of an Antarctic benthic community to iceberg disturbance was investigated using underwater photographs (1 m2 each) on the SE Weddell Sea shelf. This study: (1) characterises composition, coverage, number of patches and area of sessile benthic fauna, (2) describes faunal heterogeneity using MDS ordination and identifies ‘structural taxa’ of each recovery stage, and (3) analyses chan...

Periphytic algae dynamics in lentic ecosystems in the Brazilian semiarid.

The hydrological periods drive the structure and organization of aquatic communities in semiarid regions. We hypothesize that a decrease of the precipitation during the dry period will favor the development of the periphytic algal community, leading to higher richness and density in this period. To test this hypothesis, we investigated the changes in the periphytic algal community structure in ...

Comparison of primer sets for the study of Planctomycetes communities in lentic freshwater ecosystems.

In search of a primer set that could be used to study Planctomycetes dynamics in lakes and especially via fingerprinting methods, e.g. denaturing gradient gel electrophoresis (DGGE), three existing specific primer sets, developed for marine and soil systems, have been tested on water samples from four freshwater ecosystems. The first primer set (PLA46F/PLA886R) allowed PCR amplification of Plan...
