The fir (Abies gracilis) grove (Kamchatka Peninsula, Kronotsky State Nature Reserve) is a unique area for the northern part of the Russian Far East. As a result of revision of herbarium specimens and literature data a list of lichens of the fir grove was compiled, comprising 55 species. Of them, 27 species are new to the Kronotsky Reserve, 30 are firstly reported for the grove. Altogether 36 lichen epiphytes of Abies gracilis are known.

The 16S Rrna Gene

A novel hyperthermophilic, anaerobic, archaeon was isolated from a terrestrial hot spring at Uzon Caldera, Kronotsky Nature Reserve, Kamchatka, Russia. The isolate, strain 1860T, grew optimally at 90–95 °C and pH 6.0–7.0. The cells were non-motile straight rods, 1.5–5.0 µm in length, covered with surface-layer lattice. Strain 1860T utilized complex proteinaceous compounds as electron donors and ferrihydrite, Fe(III) citrate, nitrate, thiosulfate, selenite, selenate and arsenate as electron acceptors for growth. The sequence of the 16S rRNA gene of strain 1860T had 97.9–98.7 % similarity with those of members of the genus Pyrobaculum . On the basis of its physiological properties and phylogenetic analyses including in silico genome to genome hybridization, the isolate is considered to represent a novel species, for which the name Pyrobaculum ferrireducens sp. nov. is proposed. The type strain is 1860T ( = DSM 28942T = VKM B-2856T).

In the mid-1950's, fingernail clams virtually disappeared from a 100-mile section of the IL River, a tributary of the Mississippi River, due to unknown causes. A survey of the bottom fauna of the IL River in 1979, revealed that the clams were still absent from the middle reach of the River, where they had been abundant prior to the die-off in the 1950's. Some factor(s) in the River currently prevent the clams from recolonizing areas where they were formerly abundant. Recently, clams exposed to fluoride developed abnormal grooves in the shell matrix. Fluorides are known to be protoplasmic poisons removing essential body calcium by precipitation. Since the shell consists primarily of Ca carbonate, this investigation examines the possible role of fluoride on shell formation and the poisoning of the Ca pump which can directly inhibit lateral ciliary activity on the gill.
