There is a general agreement in referring the deposition of calcareous tufa to climatic causes. Warm climates are believed favor formation due higher concentrations biogenic CO2 soils, enhancing dissolution rates CaCO3 and broader development aquatic plants that remove from spring waters. Conversely, cold considered less favorable because reduced biological activity soils lesser plants. Dry als...

The biodiversity assessment of different taxa of the genus Caulerpa is of interest from the context of morphological plasticity, invasive potential of some species and biotechnological and pharmacological applications. The present study investigated the identification and molecular phylogeny of different species of Caulerpa occurring along the Indian coast inferred from tufA, rbcL, 18S rDNA and...

Abstract Mycobacteria were isolated from a variety of materials such as soil, peat, humus, tufa, sphagnum, and wood, collected in alpine and subalpine habitats. Mycobacteria, including Mycobacterium kansasii, Mycobacterium malmoense, Mycobacterium szulgai, Mycobacterium gordonae, Mycobacterium terrae, Mycobacterium chelonae, and Mycobacterium fortuitum were recovered from 69 of 81 (85%) samples...

Travertine/Tufa landscape is an important heritage and ecological wealth given to mankind by nature. itself has excellent scientific aesthetic value, mostly with geological archives such as volcanoes, tectonics, glaciers, well fingerprints referring climate evolution of life. However, these travertine/tufa landscapes also face degradation disappearance caused change, natural disasters, human ac...

To study the geological environmental records of alpine-karst-type tufa deposits in eastern margin Tibetan Plateau, calcareous profile exposed by “8.8” Jiuzhaigou earthquake was taken as research object and combined with a field investigation. Further, petrography, sedimentology, chronology, elemental geochemistry were studied analyzed. The results show following. (1) Sparkling Lake deposited u...
