A Coupled Extended Finite Element–Cohesive Zone Model for Hydraulic Fracture Propagation Under Poroelastic Effects Across Different Propagation Regimes

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Vitex oreadica and V. umbellata (Lamiaceae): two new species from Cerrado and Atlantic forest of Brazil

open access: yesNordic Journal of Botany, EarlyView.
Vitex L. is a pantropical genus of Lamiaceae comprising 209 taxa. Brazil harbors 35 species, representing nearly 50% of the genus richness in the Neotropics, with the Amazon showing the highest richness, followed by the Atlantic Forest and Cerrado domains. Nevertheless, most taxonomic studies of the genus have been conducted in Africa and Asia.

Landscape diversity facilitates population growth and abundance of polyphagous Lygus pratensis in cotton fields of northern Xinjiang

open access: yesNew Plant Protection, EarlyView.
Increased landscape diversity showed significantly positive effects on the population growth rate and abundance of polyphagous Lygus pratensis in cotton fields, which may be attributed to the enhanced continuity and heterogeneity of host plant resources in more diverse agricultural landscapes.

Weight Change Between Pregnancies and Mortality Over 50 Years of Follow‐Up

open access: yesObesity, EarlyView.
ABSTRACT Objective This study aimed to evaluate the link between postpartum weight retention (PPWR) and long‐term mortality. Methods In this secondary analysis of 8165 women with ≥ 2 pregnancies in the Collaborative Perinatal Project (CPP), U.S., 1959–1966, with vital status follow‐up through 2016, we used interconception weight change (ICWC) and ...

From the brink of extinction to regulation: northern Europe's white‐tailed eagles now face density dependence and climate constraints after rapid population growth

open access: yesOikos, EarlyView.
Population growth reflects the combined influence of regulation and density‐independent factors operating through demographic processes. Under exceptional circumstances (e.g. populations recovering from near‐extinction), growth may initially be weakly regulated but typically slows as negative density dependence (NDD) sets in.

When wolves aren't enough: revisiting trophic cascades in northern Wisconsin

open access: yesOikos, EarlyView.
Elimination of top predators has allowed large herbivores to flourish in many terrestrial ecosystems, transforming food webs and ecosystem functions. Restoration of large predator communities is hoped to reverse negative effects of this trophic downgrading, but evidence for such effects is elusive.
