The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian) [PDF]

, 2006
The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils.

Transcriptomic responses of sponge holobionts to in situ, seasonal anoxia and hypoxia

Peer Community Journal
Deoxygenation can be fatal for many marine animals; however, some sponge species are tolerant of hypoxia and anoxia. Indeed, two sponge species, Eurypon sp. 2 and Hymeraphia stellifera, survive seasonal anoxia for months at a time.

Anoxia Tolerant Brains [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2004
While medical science has struggled to find ways to counteract anoxic brain damage with limited success, evolution has repeatedly solved this problem. The best-studied examples of anoxia-tolerant vertebrates are the crucian carp and some North American Freshwater turtles. These can survive anoxia for days to months, depending of temperature.

The use of the ethanol pathway in goldfish Carassius auratus (L.) following anoxia [PDF]

, 2001
Goldfish (Carassius auratus) were subjected, for a period of 6 weeks, to 2h progressive hypoxia followed by 6h anoxia in closed respirometers at 15 degree C.

Duration and Intensity of End‐Permian Marine Anoxia

Geochemistry, Geophysics, Geosystems, 2022
Ocean anoxia was an important kill mechanism in the end‐Permian mass extinction and uranium isotope data are among the most powerful tools for quantifying the global extent and duration of ocean deoxygenation due to the dependence of uranium isotope ...

Structural and functional responses of harpacticoid copepods to anoxia in the Northern Adriatic: an experimental approach [PDF]

Biogeosciences, 2013
Combined in situ and laboratory studies were conducted to document the effects of anoxia on the structure and functioning of meiobenthic communities, with special focus on harpacticoid copepods.

Global Cerebral Anoxia [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2002
A 57-year-old, previously healthy tourist sustained closedhead trauma during a high-speed motor vehicle collision. She was found unconscious at the scene with a Glasgow coma scale score of 3. She suffered a multitude of injuries including frontal scalp lacerations and cervical cord injury.

Seawater redox variations during the deposition of the Kimmeridge Clay Formation, United Kingdom (Upper Jurassic): evidence from molybdenum isotopes and trace metal ratios [PDF]

, 2010
The Kimmeridge Clay Formation (KCF) and its equivalents worldwide represent one of the most prolonged periods of organic carbon accumulation of the Mesozoic.

Biogeochemical effects of volcanic degassing on the oxygen-state of the oceans during the Cenomanian/Turonian Anoxic Event 2 [PDF]

, 2011
FINAL ID: PP11A-1769 Cretaceous anoxic events may have been triggered by massive volcanic CO2 degassing as large igneous provinces (LIPs) were emplaced on the seafloor.

Anoxia Tolerance and Sugar Level in Roots and Coleoptiles of Aerobically Germinated Rice

Plant Production Science, 2011
The root and coleoptile growth of aerobically germinated rice (Oryza sativa L.) seedlings was suppressed by anoxic stress, but the suppression was more conspicuous in roots than in coleoptiles.
