The Aleutian Islands were colonized, perhaps several times, from the Alaskan mainland. Earlier work documented transitions in the relative frequencies of mtDNA haplogroups over time, but little is known about potential source populations for prehistoric Aleut migrants. As part of a pilot investigation, we sequenced the mtDNA first hypervariable region (HVRI) in samples from two archaeological s...

Malaysia has a great number of hot springs, especially along the flank of the Banjaran Titiwangsa mountain range. Biological studies of the Malaysian hot springs are rare because of the lack of comprehensive information on their microbial communities. In this study, we report a cultivation-independent census to describe microbial communities in six hot springs. The Ulu Slim (US), Sungai Klah (S...

Vickers Hot Springs is located near the rural Southern California town of Ojai, and local residents have long enjoyed soaking in the sulfuric pools. But as knowledge of the springs spread, the area saw increases in fights, traffic, burglaries, and drug use. In response, two residents purchased the land and committed to restore the property while allowing limited public access, subsequently gene...

Introduction:  All of  the  people worldwide  are exposed  to  low levels  of  radiation. Cancer induction  and  genetic disorders are among the hazards of low level exposure. In some cases, radiation close to hot springs is  higher than normal areas due to a high concentration and the decay products of Ra-226. Given the use of hot  springs by the general public  because  of their therapeutic p...

What is the diversity of cyanobacteria in iron-depositing hot springs? We are currently conducting preliminary studies on the diversity of iron-tolerant CB isolated from irondepositing hot springs in and around Yellowstone National Park (WY, USA). Molecular analysis has confirmed the prediction [1] that the diversity of iron-tolerant CB is ill-defined. Analysis of 16S rRNA sequences from 15 uni...

Here, we report the annotated draft genome sequences of nine different cyanobacteria, which were originally collected from different habitats, including hot springs, terrestrial, freshwater, and marine environments, and cover four of the five morphological subsections of cyanobacteria.

The Geobacillus icigianus G1w1(T) strain was isolated from sludge samples of unnamed vaporing hydrothermal (97°С) outlets situated in a geyser in the Troinoy region (Valley of Geysers, Kronotsky Nature Reserve, Kamchatka, Russian Federation; 54°25'51.40″N, 160°7'41.40″E). The sequenced and annotated genome is 3,457,810 bp and encodes 3,342 genes.
