Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Origin of Glaciation

open access: yes
This site provides animations useful for teaching about global cooling and the way glaciation originates. Visualizations illustrate and explain the effects of Milankovitch Cycles and fluctuations in atmospheric carbon dioxide leading to "Snowball Earth ...

Bryozoan‐Rich Carbonate Units of the Erfoud Area (SE Morocco) Record Latest Katian to Early Hirnantian Interglacial Intervals

open access: yesGeological Journal, EarlyView.
In this study, we re‐examine the depositional architecture of the Erfoud limestone in Morocco. Introducing new biostratigraphic constraints from chitinozoan assemblages, we show that Katian to Hirnantian bryozoan‐pelmatozoan meadows reflect flooding events linked to a series of interglacial transgressions known to have occurred immediately prior to the

ExMODE: A comprehensive resource for extremophile genomic and functional exploration

open access: yesiMetaOmics, EarlyView.
ExMODE (https://db.genomics.cn/exmode/) integrates 3518 samples to build a unified extremophile resource, which hosts 1.35 billion habitat‐specific non‐redundant genes, 5.25 million representative protein structures, 67,026 metagenome‐assembled genomes (MAGs), and 164,132 biosynthetic gene clusters (BGCs). By combining sequence‐, structure‐, and genome‐

Hematological and Genotoxic Effects of Subchronic Oral Exposure to a Mancozeb‐Based Fungicide in Female Mice

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...
