Fungal event and palynological record of ecological crisis and recovery across the Permian-Triassic boundary

  title={Fungal event and palynological record of ecological crisis and recovery across the Permian-Triassic boundary},
  author={Yoram Eshet and Michael R. Rampino and Henk Visscher},
The end of the Permian Period was marked by the most severe mass extinction in the geologic record. Detailed quantitative study of pollen and spores from shallow-marine deposits spanning the Permian-Triassic (P-Tr) boundary in Israel reveals a sequence of palynological-ecological stages reflecting a major crisis among land plants. The disappearance of the gymnosperm-dominated palynoflora of the Late Permian Lueckisporites virkkiae Zone is recorded at a claystone horizon containing almost…

Landscape ecological shift at the Permian‐Triassic boundary in Antarctica
Palaeosols across the Permian‐Triassic boundary in Antarctica provide evidence of a marked change in ecosystems at this greatest of all extinctions in the history of life on Earth. The boundary can
Interpretation of “fungal spikes” in Permian-Triassic boundary sections
Refined Permian–Triassic floristic timeline reveals early collapse and delayed recovery of south polar terrestrial ecosystems
The collapse of late Permian (Lopingian) Gondwanan floras, characterized by the extinction of glossopterid gymnosperms, heralded the end of one of the most enduring and extensive biomes in Earth’s
Phytoplankton (acritarch) community changes during the Permian-Triassic transition in South China
Life in the end-Permian dead zone
The significant time lag between terrestrial ecosystem collapse and selective extinction among characteristic Late Permian plants is documented, and the time-delayed, end-Permian plant extinctions resemble modeled “extinction debt” responses of multispecies metapopulations to progressive habitat destruction.
Multiple climatic changes around the Permian-Triassic boundary event revealed by an expanded palynological record from mid-Norway
Here, we present the palynological record from two shallow core holes (6611/09-U-01 and -02) from the Trondelag Platform offshore mid-Norway consisting of 750 m of Upper Permian and Lower Triassic

Early Triassic stromatolites as post-mass extinction disaster forms
Aftermaths of mass extinctions have been thought to be characterized by relaxation of ecological constraints accompanied by increased prominence of opportunistic generalists. Such taxa, termed
Permian-Triassic extinction: Organic δ13C evidence from British Columbia, Canada
The Permian-Triassic (P-T) extinction is documented geochemically in a marine sequence deposited in a basinal setting at Williston Lake, northeastern British Columbia, by using elemental and isotopic
Palynology of the Permian succession of Spitsbergen, Svalbard
Palynological investigations of 16 sections from Spitsbergen, Svalbard, covering the uppermost Carboniferous, Permian and lowermost Triassic succession have been carried out. Because of general poor
Parallel trends in organic and inorganic carbon isotopes across the Permian/Triassic boundary
Stable carbon isotope ratios in both inorganic and organic reservoirs have been widely applied to model environmental and sedimentological changes on a global scale. Most studies dealing with major
It seems inescapable that large impacts have been an ongoing phenomenon throughout geological time. In the Phanerozoic the estimated frequency of impact by bodies of 5-km diameter or more is on the
