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

Geological 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 ...

The nitrogen dilemma: Toward a novel fertilization management framework for reconciling productivity and diversity in grasslands

Grassland Research, EarlyView.
Nitrogen fertilization raises grassland productivity but steadily undermines plant diversity. Instead of applying the same rate everywhere every year, the PRISM framework is designed to rotate high‐ and low‐nitrogen paddocks across the farm over time. This spatiotemporal cycling aims to maintain farm‐scale productivity while creating periodic windows ...

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Exposure–Recovery Approach for Hepatic Toxicity Analysis of Pyrethroid Lambda‐Cyhalothrin: Histopathological, Histochemical, and Biochemical Responses in Oreochromis niloticus

Journal of Applied Toxicology, EarlyView.
ABSTRACT Lambda‐cyhalothrin is a synthetic pyrethroid insecticide widely used in agriculture, but its potential to contaminate aquatic ecosystems and exert high toxicity on fish at low concentrations raises ecotoxicological concerns. While standard histopathological and biochemical assessments are common, the novel integration of pigment‐based ...

Young adult self‐harm: The role of victimisation and polygenic risk in a population‐based longitudinal study

JCPP Advances, EarlyView.
Abstract Background Victimisation has been associated with self‐harm (with or without suicidal intent), but little is known about this association during young adulthood—a distinct developmental period. Further, not all individuals who experience victimisation will later engage in self‐harm, suggesting the influence of other factors.
