Nature and Timing of Biotic Recovery in Antarctic Benthic Marine Ecosystems Following the Cretaceous–Palaeogene Mass Extinction [PDF]

open access: yesPalaeontology, 2019
AbstractTaxonomic and ecological recovery from the Cretaceous–Palaeogene (K–Pg) mass extinction 66 million years ago shaped the composition and structure of modern ecosystems. The timing and nature of recovery has been linked to many factors including palaeolatitude, geographical range, the ecology of survivors, incumbency and palaeoenvironmental ...

Unique Microgastropod Biofacies in the Early Triassic: Indicator of Long-Term Biotic Stress and the Pattern of Biotic Recovery After the End-Permian Mass Extinction

open access: yesComptes Rendus - Palevol, 2005
Abstract Microgastropod-dominated shell beds formed during the aftermath of the end-Permian mass extinction comprise a characteristic Early Triassic biofacies. The identification of this biofacies is significant: (1) no other episode in the geologic record is characterized by the lack of larger gastropods and abundant, conspicuous microgastropod ...

Recent turbidite deposition in the eastern Atlantic: Early diagenesis and biotic recovery

Journal of Marine Research, 2002
An interface core taken in Capbreton canyon shows a succession of sedimentary facies interpreted as classical Bouma turbiditic sequences. Activities of 234Th and 210Pb suggest that the deposition of the most recent turbidite was triggered by the violent storm that affected the Atlantic coast of southern France on the 27th of December 1999, about four ...

The timing and pattern of biotic recovery following the end-Permian mass extinction

Nature Geoscience, 2012
The aftermath of the great end-Permian period mass extinction 252 Myr ago shows how life can recover from the loss of >90% species globally. The crisis was triggered by a number of physical environmental shocks (global warming, acid rain, ocean acidification and ocean anoxia), and some of these were repeated over the next 5-6 Myr.

Increasing Diversity and Biotic Homogenization of Lake Plankton During Recovery from Acidification

2022
Determining biodiversity responses to environmental change, such as acidification, is critical for ecosystem projections under future global change scenarios. Here, we analyzed the community compositions of phytoplankton, crustaceans and rotifers in 28 lakes in the Adirondack Park, USA, during 1994-2012, and examined the spatiotemporal trends in their ...

Dienerian (Early Triassic) ammonoids and the Early Triassic biotic recovery: a review

2018
It 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

Macroinvertebrate Recovery of a Post-Thermal Stream: Habitat Structure and Biotic Function

Ecological Engineering, 2000
Abstract Macroinvertebrate faunal assemblages, organic matter availability and instream structural complexity were investigated in three systems to determine the current state of recovery of a post-thermal stream. The abundance and diversity of the lower foodchain community has recovered substantially since cessation of thermal flows in 1988; however,

Biotic response to explosive volcanism: Ostracod recovery after Ordovician ash-falls

Palaeogeography, Palaeoclimatology, Palaeoecology, 2012
Abstract 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).

Elevated atmospheric CO2 and the delayed biotic recovery from the end-Permian mass extinction

Palaeogeography, Palaeoclimatology, Palaeoecology, 2007
Excessive 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 ...
