Selenate and sulfide are both contaminants which severely pollute water bodies. Respective bioremediation of selenate- and sulfide-contaminated wastewaters requires abundant electron donors and acceptors. Here, we present a novel concept coupling biological selenate to selenite (shortcut deselenization) and chemical sulfide-driven selenite reduction ...

Biotic response to explosive volcanism: Ostracod recovery after Ordovician ash-falls
Palaeogeography, Palaeoclimatology, Palaeoecology, 2012Abstract The impact of two Ordovician ash-falls of different intensities was studied in order to determine the recovery patterns of benthic ostracods. The studied sections are of Sandbian age in NW Estonia: at Poosaspea, the Kinnekulle K-bentonite (~ 40 cm, derived from a major volcanic event) and at Ristna, the Grimstorp bentonite (~ 6 cm).

Dienerian (Early Triassic) ammonoids and the Early Triassic biotic recovery: a review
2018It has been estimated that about 90% of all marine species disappeared during the end-Permian mass extinction (Raup & Sepkoski 1982). It is the biggest known biodiversity crisis in the history of Phanerozoic life, and it led to the replacement of typical Palaeozoic faunas by typical modern communities (Sepkoski 1984). The recovery which followed in

Native sagebrush ecosystems in the Great Basin (western USA) are often invaded following fire by exotic Bromus tectorum (cheatgrass), a highly flammable annual grass. Once B. tectorum is established, higher fire frequencies can lead to local extirpation of Artemisia tridentata ssp.

Elevated atmospheric CO2 and the delayed biotic recovery from the end-Permian mass extinction
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007Excessive CO2 in the Earth ocean–atmosphere system may have been a significant factor in causing the end-Permian mass extinction. CO2 injected into the atmosphere by the Siberian Traps has been postulated as a major factor leading to the end-Permian mass extinction by facilitating global warming, widespread ocean stratification, and development of ...

Detailed microfacies and paleoenvironmental analyses were conducted through the Early Triassic interval of the outer platform ammonoid-rich series of the Nanpanjiang Basin (Luolou Formation, Guangxi Province, South China). Extensive investigations on outcrops and on thin sections reveal that the widely reported well-diversified latest Permian fauna ...

AbstractThe recovery of a temperate zone biotic community in a lotic freshwater habitat after acute chlorine poisoning was nearly completed in four months (May to September). This was facilitated by the water flow, which rapidly removed the toxic residues of the chlorine and transported organisms from the intact community upstream into the impoverished

Biotic recovery from the Late Devonian F-F mass extinction event in China
Science in China Series D: Earth Sciences, 2002The Frasnian-Famennian (F-F) mass extinction is one of the five great extinctions of marine life during the Phanerozoic. The F-F event killed most of the Devonian reefs, the characteristic Devonian corals, stromatoporoids, bryozoans, nearly all tentaculites, a few superfamilies of brachiopods, such as Atrypacea and Pentameracea and some important ...
