A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Synthetic Aperture Radar backscatter for automated delineation of the Disko Island glaciers

, 2020
Breer er sensitive indikatorer på klimaendringer og utgjør den største samling fer- skvann på Jorda. På grunn av isbreenes direkte respons til små forandringer i kli- masystemet har breene fått mye oppmerksomhet de siste årene. For å kunne varsle om farene for folk og infrastruktur som følge av bresmelting slik som flom og skred, er det viktig å ...

The extension of the taxon cycle model to island plants: insights from the Canarian vascular flora

Biological Reviews, EarlyView.
ABSTRACT Taxon cycle models describe eco‐evolutionary patterns of lineage colonization, diversification, and decline across archipelagos, inferring an important role for competition amongst ecologically similar taxa in driving concurrent niche changes.

Orchard netting impacts on biodiversity leading to cascading effects at the ecosystem level

Biological Reviews, EarlyView.
ABSTRACT Agriculture must ensure food production without further compromising the ecosystem functions upon which it depends. Agricultural practices should therefore avoid harming farmland biodiversity, especially of taxa that supply the key ecosystem services (e.g.

Positional Relationship Between the Orbicularis Oculi and Zygomaticus Complex Muscles by Ultrasonography: New Anatomical Insights for Crow's Feet Injection

Clinical Anatomy, EarlyView.
ABSTRACT The orbicularis oculi muscle (OOc) is strongly associated with facial aging as its contraction causes the formation of crow's feet. Botulinum neurotoxin (BoNT) injection is a representative treatment targeting muscle. The aim of this study was to demonstrate the anatomical relationship between the OOc and the zygomaticus complex muscles, and ...

Analysis of the glacier retreat in the French Alps since the 1960s based on the new glacier inventory

, 2012
One of the most obvious impacts of climate change in high mountain areas is the glacial retreat. Since the French glacier inventory carried out by R.

Synthesis and Functional Properties of Fluorinated Phosphonate‐Substituted Porphyrins: Excellent Photosensitizers and Robust Precursors for Photoactive Langmuir–Schaefer Films

Chemistry – A European Journal, EarlyView.
This is a comprehensive study of new family of high functionalized meso‐tetraarylporphyrins. A synthetic approach to phosphonate‐substituted fluorinated porphyrins was developed. These compounds were investigated with respect to singlet oxygen generation and photostability.

Measurements of snow- and glacier-covered areas with single-polarization SAR

, 1993
Climatological and hydrological investigations in mountainous regions frequently require delineation of the areas covered by snow and glacial ice. Active microwave sensors can discriminate snow and glacier from other targets, are effective under all ...

A Deep Learning-Based Framework for the Automatic Extraction of Clean Ice / Snow on the Tibetan Plateau

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
With the acceleration of global warming, glaciers on the Tibetan Plateau (TP) are retreating rapidly, threatening the long-term water supply and ecological stability of the TP and its surrounding regions.

Titanium‐Catalyzed Diastereoselective Keto‐ and Iminonitrile Cyclizations

Chemistry – A European Journal, EarlyView.
The titanium(III)‐catalyzed diastereoselective cyclization of readily‐available substituted ketonitriles gives cyclopentanones in good yield and stereoselectivity. Subsequent 1,2‐addition allows the preparation of cyclopentyls with three consecutive stereocenters.
