The present paper focuses on the epipelic cyanobacteria and algae (particularly desmids). Altogether 45 sediment samples were taken at ponds covering a pH/conductivity and trophic gradients. Statistic evaluation based on environmental variables measured, divided localities into four major groups differing also by sediment quality and its algal flora. Altogether 39 cyanobacterial species were fo...

Ocean acidification is expected to alter marine systems, but there is uncertainty about its effects due to the logistical difficulties of testing its large-scale and long-term effects. Responses of biological communities to increases in carbon dioxide can be assessed at CO2 seeps that cause chronic exposure to lower seawater pH over localised areas of seabed. Shifts in macroalgal communities ha...

Falkowski et al. (1) reviewed the evidence that three disparate groups of algae— dinoflagellates, diatoms, and coccolitho-phores, each with plastids derived from red algae by secondary endosymbiosis—have come to dominate the oceans_ flora over the past 250 million years and speculated about the forces responsible for this domination. Central to this speculation is the Bportable plastid hypothes...

This article found that 123 species and of microscopic algae, belonging to 4 divisions, 9 classes, 19 orders, 25 families, 32 genera, are distributed in the algal flora Dengizkol reservoir. When analyzing algae natural reservoir contour sections, it was number is high areas where water flows into lake, low remote from inflow water. In particular, 114 phytoplankton were 1st circuit collector, 10...

A survey of the marine plants of the Walpole and Nornalup Inlets Marine Park has recorded 49 species of marine benthic algae and seagrasses, including 15 green algae, 11 brown algae, 18 red algae, 4 seagrasses, and one cyanobacterium, representing a substantial increase on the 14 previously recorded species. Most species are relatively common elements of the south-western Australian marine flor...
