Microfossil assemblages and geochemistry for interpreting the incidence of the Jenkyns Event (early Toarcian) in the south-eastern Iberian Palaeomargin (External Subbetic, SE Spain) [PDF]

open access: yesJournal of Micropalaeontology, 2020
By studying the facies, geochemistry, and microfossil assemblages of the uppermost Pliensbachian and lower Toarcian of the Cueva del Agua section, I was able to appraise the impact of the Jenkyns Event in the eastern part of the South Iberian ...

The main stage of recovery after the end-Permian mass extinction: taxonomic rediversification and ecologic reorganization of marine level-bottom communities during the Middle Triassic [PDF]

open access: yesPeerJ, 2021
The recovery of marine life from the end-Permian mass extinction event provides a test-case for biodiversification models in general, but few studies have addressed this episode in its full length and ecological context.

Lessons from the past: Biotic recoveries from mass extinctions [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
Although mass extinctions probably account for the disappearance of less than 5% of all extinct species, the evolutionary opportunities they have created have had a disproportionate effect on the history of life. Theoretical considerations and simulations have suggested that the empty niches created by a mass extinction should refill rapidly after ...

Ferns as facilitators of community recovery following biotic upheaval

open access: yesBioScience
Abstract The competitive success of ferns has been foundational to hypotheses about terrestrial recolonization following biotic upheaval, from wildfires to the Cretaceous–Paleogene asteroid impact (66 million years ago). Rapid fern recolonization in primary successional environments has been hypothesized to be driven by ferns’ high spore

Patterns of fossil distributions within their environmental context from the Middle Triassic in South Canyon, Central Nevada, USA

open access: yesJournal of Palaeogeography, 2014
The Middle Triassic records the return of diverse marine communities after the severe effects of the end-Permian mass extinction. This diversification leads to the Mesozoic/modern adaptive radiation resulting in substantial changes in marine communities ...

New keratose sponges after the end‐Permian extinction provide insights into biotic recoveries

open access: yesGeobiology, 2023
AbstractWe challenge the prevailing view that the end‐Permian extinction impeded the Triassic evolution of sponges. Here, we report a deep‐water community dominated by abundant keratose sponges in the lowest Triassic strata from Southwest China. The sponge fossils occur as dark elliptical imprints in mudstone with distinct oscula on their tops.

Trace fossils as proxy for biotic recovery after the end-Permian mass extinction: A critical review [PDF]

open access: yes, 2022
Trace fossils represent records of the activity of both epifaunal and infaunal animals, providing significant information for a deeper understanding of Earth's past environments and ecosystems.

Low flows and recovery of macroinvertebrates in a small regulated chalk stream [PDF]

open access: yes, 1994
The ecological effects of, and subsequent recovery from, a protracted drought exacerbated by groundwater abstractions on a small English chalk stream are described. Preliminary data from 15 sites showed significant physical and biotic changes between two

Environmental Cues Contribute to Dynamic Plasma Membrane Organization of Nanodomains Containing Flotillin-1 and Hypersensitive Induced Reaction-1 Proteins in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2022
Plasma membranes are heterogeneous and contain multiple functional nanodomains. Although several signaling proteins have been shown to function by moving into or out of nanodomains, little is known regarding the effects of environmental cues on ...

Abiotic and biotic drivers of temporal dynamics in the spatial heterogeneity of zooplankton communities across lakes in recovery from eutrophication [PDF]

open access: yes, 2021
Seasonal and annual dynamics of the zooplankton community in lakes are affected by changes in abiotic drivers, trophic interactions (e.g., changes in phytoplankton and fish communities and abundances) and habitat characteristics (e.g.
