Increasing diversity and biotic homogenization of lake plankton during recovery from acidification
Science of the Total Environment, 2023Determining biodiversity responses to environmental change, such as acidification, is critical for ecosystem projections under future global change scenarios. Here, we analyzed three plankton communities of phytoplankton, crustaceans and rotifers in 28 lakes in the Adirondack Park, USA, during 1994-2012, and examined the spatiotemporal trends in their ...

Exceptional continental record of biotic recovery after the Cretaceous–Paleogene mass extinction
Science, 2019Terrestrial 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

Biotic Responses along the Recovery Gradient of a Regulated Stream
Canadian Journal of Fisheries and Aquatic Sciences, 1991Samples 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
1994The 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 ...

Comptes 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 ...

Nature and timing of biotic recovery in Antarctic benthic marine ecosystems following the Cretaceous–Palaeogene mass extinction [PDF]
Palaeontology, 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 ...

The timing and pattern of biotic recovery following the end-Permian mass extinction
Nature Geoscience, 2012The 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.

Recent turbidite deposition in the eastern Atlantic: Early diagenesis and biotic recovery
Journal of Marine Research, 2002An 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 ...

Macroinvertebrate recovery of a post-thermal stream: habitat structure and biotic function
Ecological Engineering, 2000Abstract 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,
