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...

Based on the floristic study of rust fungus flora (Uredinales) ofGolestan National Park, located in the Northeast of Iran, 68 rust taxa were recognized. Of these, one subspecies and five species viz. Phragmidium sanguisorbae subsp. mediterraneum on Sanguiosorba minor, Puccinia difformis on Galium aparine, P. jasmini on Jasminum fruticans, P. rhylismoides on Thalictrum isopyroides, Uromyces mogi...

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...
