Saltcedar (Tamarix pentandra Pall.) stem cuttings responded vegetatively to various photoperiods of 11-, 14-, 17-, and 8 + 1-hour duration. Total stem length, average stem length, cuticle thickness, and xylem vessel member outside diameter were significantly maximal under a 14-hour photoperiod and less under photoperiods above and below this level. Numbers of stems and roots produced were signi...

Armillaria altimontana, previously considered North American biological species (NABS) X, is described as new. To date, it appears that A. altimontana prefers higher-elevation, mesic sites within the dry, conifer forest zone of western interior North America. This species has been found on hardwoods and conifers and is associated most commonly with Abies-dominated forest types in southern Briti...

Four vahlkampfiid amoebae were isolated from freshwater samples taken on the island of Tenerife. Ribosomal DNA sequence analysis identified two isolates to belong to the genus Naegleria, representing novel species with their closest relatives N. gallica and N. philippinensis respectively. The two other isolates belong to the genus Vahlkampfia and represent also novel species, with as their clos...

The phylogenetic structure of genus Micromonospora within actinomycetes was examined by analysing the gyrB sequences of 15 validly described species and four subspecies. All but one of the Micromonospora strains formed a tight cluster, as had previously been demonstrated by a 16S rDNA-based phylogenetic analysis. However, the intrageneric relationships deduced from the gyrB-based phylogeny were...

Dynamics of eternal inflation on the landscape admits description in terms of the Martin-Siggia-Rose (MSR) effective field theory that is in one-to-one correspondence with vacuum dynamics equations. On those sectors of the landscape, where transport properties of the probability measure for eternal inflation are important, renormalization group fixed points of the MSR effective action determine...
