RNAi of HvMMP2 Affects Larval-Pupal Transition and Adult Eclosion in the Henosepilachna vigintioctopunctata

open access: yesInsects
Henosepilachna vigintioctopunctata is a major pest of solanaceous crops. Matrix metalloproteinase 2 (MMP2) is a zinc ion-dependent endopeptidase that plays a crucial role in the remodeling process of the extracellular matrix (ECM) within cells.

Of Elephants and Other Mammals: A Comparative Review of Reproductive Tumors and Potential Impact on Conservation

open access: yesAnimals, 2022
Reproductive tumors can impact conception, pregnancy, and birth in mammals. These impacts are well documented in humans, while data in other mammals are limited.

Borosulfates Hosting Se42+ Ions—Crystal Structures, Chemical Bonding, Optical Spectroscopy, and Magnetism

open access: yesAngewandte Chemie, EarlyView.
Apart from (transition) metal (oxo)halides only few hosts stabilize chalcogenide cations in purely oxoanionic coordination environment. Herein, we report on five borosulfates containing the Se42+ ion and characterize the compounds using X‐ray diffraction, diffuse reflectance spectroscopy, density functional theory (DFT) calculations along with magnetic

Exotic urban trees conserve similar natural enemy communities to native congeners but have fewer pests [PDF]

open access: yesPeerJ, 2019
Urban trees serve a critical conservation function by supporting arthropod and vertebrate communities but are often subject to arthropod pest infestations. Native trees are thought to support richer arthropod communities than exotic trees but may also be

A comparative analysis of indigenous and exotic tree species management practices in agricultural landscapes of Southwest Ethiopia

open access: yesTrees, Forests and People, 2021
A substantial tree planting from exotic tree species has been practiced in Ethiopia during the last ten decades. Yet, the efforts made to restore degraded areas using exotic tree species but with less emphasis given to the indigenous tree species for ...

Local extinction and colonisation in native and exotic fish in relation to changes in land use [PDF]

open access: yes, 2011
Distribution patterns of many native and exotic fish species are well documented, yet little is known about the temporal dynamics of native and exotic diversity in relation to changes in land use.

Electrostatic Superlattices Beyond 1:1 Stoichiometry

open access: yesAdvanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Suppression of Peierls Instability in a Metal−Halide Porous Framework

open access: yesAngewandte Chemie, EarlyView.
Peierls distortion in one‐dimensional Pt‐I chains is suppressed by confinement within the periodic electrostatic environment of a porous Cu–I framework. X‐ray crystallography shows equivalent Pt–I distances without bond alternation, and conductivity of the Pt‐I chains is greatly enhanced.

New state records of the woodlouse spider Dysdera crocata C. L. Koch, 1838 (Araneae: Dysderidae) in Mexico

open access: yesRevista Chilena de Entomología, 2022
The woodlouse spider Dysdera crocata C. L. Koch, native to the Old World, is recorded for the Mexican state of Nuevo León via the revision of vouchered specimens; it is also recorded for the states of Baja California, Guanajuato, Hidalgo, San Luis Potosí,

Phase Engineering of Nanomaterials (PEN): Evolution, Current Challenges, and Future Opportunities

open access: yesAdvanced Materials, EarlyView.
This review summarizes the synthesis, phase transition, advanced characterization spanning ex situ to in situ and operando techniques, and diverse applications of phase engineering of nanomaterials (PEN). It further outlines key challenges and future opportunities, such as phase stability, architecture control, and artificial intelligence (AI)‐driven ...
