Diversity and abundance of soil algae in the polar desert, Sverdrup Pass, central Ellesmere Island // Polar Record, 1999. Vol. 35 (194). P. 231-254. Cyanobacteria and eukaryotic algae were investigated during three seasons in 18 plots established across Sverdrup Pass valley of central ElIesmere Island, 79°N, Canada. The sites differed in altitude, substratum, and other characteristics. A high species diversity total\ed 136 taxa. Cyanobacteria accounted for 52 and eukaryotic algae 84 species. In both groups, numerous species did not correspond to any taxa described. However, high diversity did not always coincide with high algal abundance or biomass. On older and stable landscapes, visible crusts developed, containing mostly cyanobacteria, fungi, and other microbial components. Considerable variation in algal diversity and abundance was found among the sites. Also the southern, granitic portion ofthe pass was richer in green algae compared to its northern, dolomitic port ion where motile cyanobacteria were more prominent. These micro-autotrophs occupied the soil profile to a depth of 7 cm. Their highest density was not at the surface but at 3-4 cm depth. One plot was contaminated by windblown copper-rich dust from a nearby outcrop and soil here was poorest in content of photosynthetic pigments, suggesting a local heavy-metal toxicity. en http://kpabg.ru/cyanopro/?q=node/3703 <div class="field field-name-field-newspecies field-type-taxonomy-term-reference field-label-hidden"><div class="field-items"><div class="field-item even"><a href="/cyanopro/?q=taxonomy/term/82" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Cyanothece aeruginosa (Nägeli) Komárek</a></div><div class="field-item odd"><a href="/cyanopro/?q=taxonomy/term/880" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Trichocoleus tenerrimus (Gomont) Anagnostidis</a></div><div class="field-item even"><a href="/cyanopro/?q=taxonomy/term/102" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Microcoleus autumnalis (Trevisan ex Gomont) Strunecky et al.</a></div><div class="field-item odd"><a href="/cyanopro/?q=taxonomy/term/126" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Microcoleus vaginatus Gomont ex Gomont</a></div><div class="field-item even"><a href="/cyanopro/?q=taxonomy/term/103" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Hassallia byssoidea Hassall ex Bornet et Flahault</a></div><div class="field-item odd"><a href="/cyanopro/?q=taxonomy/term/881" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Nostoc edaphicum Kondrateva</a></div><div class="field-item even"><a href="/cyanopro/?q=taxonomy/term/187" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Leptolyngbya valderiana (Gomont) Anagnostidis et Komárek</a></div><div class="field-item odd"><a href="/cyanopro/?q=taxonomy/term/738" typeof="skos:Concept" property="rdfs:label skos:prefLabel" datatype="">Leptolyngbya edaphica (Elenkin) Anagnostidis et Komárek</a></div></div></div><div class="field field-name-field-coord field-type-geofield field-label-hidden"><div class="field-items"><div class="field-item even">Latitude: 79.1371605 <br/>Longitude: -79.7717285</div></div></div><div class="field field-name-field-cprec field-type-number-integer field-label-inline clearfix"><div class="field-label">Coord.prec.:&nbsp;</div><div class="field-items"><div class="field-item even">1 000</div></div></div><div class="field field-name-field-location field-type-text-long field-label-hidden"><div class="field-items"><div class="field-item even">Canadian Arctic Archipelago.
