Two Epiphytic Algae

Molecular characterization of epiphytic bacterial communities on charophycean green algae

Epiphytic bacterial communities within the sheath material of three filamentous green algae, Desmidium grevillii, Hyalotheca dissiliens, and Spondylosium pulchrum (class Charophyceae, order Zygnematales), collected from a Sphagnum bog were characterized by PCR amplification, cloning, and sequencing of 16S ribosomal DNA. A total of 20 partial sequences and nine different sequence types were obta...

The trophic importance of epiphytic algae in a freshwater macrophyte system

Seagrass and epiphytic algae support nutrition of a fisheries species, Sillago schomburgkii, in adjacent intertidal habitats

The importance of organic matter produced in seagrass meadows (seagrass and epiphytic algae) to the nutrition of a valuable fisheries species (yellowfin whiting Sillago schomburgkii Peters) occurring over unvegetated mudflats was measured using the isotopic composition (δ13C, δ15N) of fish, their polychaete prey, and available autotrophic sources at several locations in southern Australia durin...

Studies of Marine Epiphytic Algae, Calvi, Corsica. I. Determination of Minimal Sampling Areas for Microscopic Algal Epiphytes

Minimal sampling areas have been determined for marine Bangiophyceae and Cyanophyceae epiphytic on Cladophora prolifera and Halopteris scoparia in Calvi, Corsica. This was done by observing the stabilization of species/area curves and of qualitative and quantitative similarity coefficients between samples of increasing size. For Cyanophyceae (studied only on Cladophora) the minimal sampling are...

Epiphytic Terrestrial Algae (Trebouxia sp.) as a Biomarker Using the Free-Air-Carbon Dioxide-Enrichment (FACE) System

The increasing concentration of CO₂ in the atmosphere has caused significant environmental changes, particularly to the lower plants such as terrestrial algae and lichens that alter species composition, and therefore can contribute to changes in community landscape. A study to understand how increased CO₂ in the atmosphere will affect algal density with minimal adjustment on its natural ecosyst...
