Suitability of Natura 2000 sites for threatened freshwater species under projected climate change

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 12, Page 1872-1887, December 2022., 2022
Abstract As part of the world's largest coordinated network of protected areas, Natura 2000, European Union member states designate special areas of conservation (SACs) to maintain or achieve favourable conservation status for imperilled aquatic species listed under Annex II of the Habitats Directive.

Manipulation of Chemistry and Biology with Visible Light Using Tetra‐ortho‐Substituted Azobenzenes and Azonium Ions

Angewandte Chemie, EarlyView.
Tetra‐ortho‐Azobenzenes (TOABs) in broad daylight: in recent years, TOAB photoswitches became indispensable tools for all‐visible‐light manipulation of chemistry, biology and materials. This review explores their unique photochemical properties, design and synthetic approaches, offering support in choosing a TOAB for a given application.

Extreme fire severity interacts with seed traits to moderate post‐fire species assemblages

American Journal of Botany, EarlyView.
Abstract Premise Climate change is globally pushing fire regimes to new extremes, with unprecedented large‐scale severe fires. Persistent soil seed banks are a key mechanism for plant species recovery after fires, but extreme fire severity may generate soil temperatures beyond thresholds seeds are adapted to.

Antler tine homologies and cervid systematics: A review of past and present controversies with special emphasis on Elaphurus davidianus

The Anatomical Record, Volume 306, Issue 1, Page 5-28, January 2023., 2023
Abstract Antlers are the most conspicuous trait of cervids and have been used in the past to establish a classification of their fossil and living representatives. Since the availability of molecular data, morphological characters have generally become less important for phylogenetic reconstructions.

Iridium(III) Carbene Complexes Featuring Either Metal‐to‐Ligand Charge Transfer (MLCT) or Through‐Space Charge Transfer (TSCT) Blue Luminescence

Angewandte Chemie, EarlyView.
Ir(III) complexes with contrasting MLCT or TSCT transition characters were synthesized, among which the TSCT emitter f‐ct13b gave PhOLED device with an EQEmax of 22.2% and CIExy of (0.155, 0.120). Additionally, hyper‐OLED bearing another TSCT sensitizer, f‐ct13c and v‐DABNA terminal emitter, achieved a narrowband blue hyperphosphorescence with EQEmax ...

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas

American Journal of Botany, EarlyView.
Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Adverse maternal environment alters Oprl1 variant expression in mouse hippocampus

The Anatomical Record, Volume 306, Issue 1, Page 162-175, January 2023., 2023
Abstract An adverse maternal environment (AME) and Western diet (WD) in early life predispose offspring toward cognitive impairment in humans and mice. Cognitive impairment associates with hippocampal dysfunction. An important regulator of hippocampal function is the hippocampal Nociceptin/Orphanin FQ (N/OFQ) system. Previous studies find links between

Donor‐π‐Acceptor Photoinitiators for High‐Efficiency Visible LED and Sunlight Polymerization and High‐Precision 3D Printing

Angewandte Chemie, EarlyView.
The proposed D‐π‐A structured dyes enable efficient electron transfer with additives, thanks to their tailored architecture, making them ideal for high‐performance photoinitiating systems. They allow the fabrication of high‐precision 3D printed objects and exhibit outstanding performance under sunlight.
