Arthrobacter are very common in many soils and are readily isolated in laboratory media and so they have been isolated extensively from soils. There are many species known and this chapter offers a detailed description of the Arthrobacter genus. This entry describes Arthrobacter species with an emphasis on the ability of many of the strains to transform anthropogenic chemicals into less toxic p...
We introduce the equivariant elliptic genus for open varieties and prove an equivariant version of the change of variable formula for blow-ups along complete intersections. In addition, we prove the equivariant elliptic genus analogue of the McKay correspondence for the ALE spaces.
The family Ephippidae consists of eight genera and 15 species. The genus Platax with five species distributed throughout Indo-Pacific, seemingly has more diversity than other genera of the family. Phylogenetic relationships among species and genera of the family, however, are not fully resolved. 48 sequences of eight species (four genera) of batfishes are available in the GenBank and have been ...
This study investigated seasonal changes in density and diversity of phytoplankton, chlorophyll a content, and some environmental characteristics in the Sistan region during 2014. Totally, we detected 28 genera that belonged to five groups of Chlorophyta (12 genera), Bacilloriophyta (7 genera), Cyanophyta (5 genera), Dinophyta (3 genera), and Euglenophyta (1 genus). We observed that Chlorophyta...
Members of the genus Erwinia are primarily plant-pathogenic and plant-associated bacteria. As modern approaches have focused on the direct analysis of genes and their gene products, commonly associated phenotypes such as the type of disease that they cause and the relatedness of rDNA have prompted splitting of certain Erwinia members into the genus Enterobacter, Pectobacterium, Pantoea or Brenn...
Accurate knowledge of the functional response of predators to prey density is essential for understanding food web dynamics, to parameterize mechanistic models of animal responses to environmental change, and for designing appropriate conservation measures. Greater flamingos (Phoenicopterus roseus), a flagship species of Mediterranean wetlands, primarily feed on Artemias (Artemia spp.) in comme...
