Exceptional continental record of biotic recovery after the Cretaceous–Paleogene mass extinction

Science, 2019
Terrestrial record of recovery The extinction that occurred at the end of the Cretaceous period is best known as the end of the nonavian dinosaurs. In theory, this paved the way for the expansion of mammals as well as other taxa, including plants. However, there are very few direct records of loss and recovery of biotic diversity

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 Responses along the Recovery Gradient of a Regulated Stream

Canadian Journal of Fisheries and Aquatic Sciences, 1991
Samples were collected year-round over a 1-yr period at six sites located downstream from a reservoir with a hypolimnetic release on the upper Colorado River to examine the longitudinal patterns of macroinvertebrates along an environmental gradient induced by river regulation.

Reorganization: Recovery of Biotic Regulation

1994
The aggrading northern hardwood ecosystem has a considerable capacity to exercise control over hydrology and biogeochemistry and to regulate the flow and use of solar energy (Chapter 2). When this control is at its maximum, the ecosystem is most stable, with highly predictable and low net losses of nutrients and a fairly constant annual ...

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.

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

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).
