Comprehensive and representative conservation planning for biodiversity of ice‐free Antarctica

open access: yesConservation Biology, EarlyView.
Abstract Antarctica is designated as a natural reserve devoted to peace and science, with Antarctic Specially Protected Areas (ASPAs) serving as the primary instrument for area‐based biodiversity protection. However, the existing ASPA network lacks the comprehensiveness and representativeness required under Annex V, Article 3(2), of the Madrid Protocol.

Island invertebrate responses to single‐ and multi‐species invasive rodent eradications

open access: yesConservation Science and Practice, EarlyView.
Eradications of rodents on islands are a powerful tool for conservation, but rarely are the responses of invertebrates quantified post‐eradication, despite being the preferred prey of mice. Here we analyzed pre‐ and post‐eradication invertebrate survey results for two sub‐Antarctic islands where mice had recently been eradicated; Antipodes Island where

Antarctica

open access: yes, 2013
Antarctica was the last continent to be discovered and colonized by people, and this has resulted in generally sparse meteorological, oceanographic and biological data for the Antarctic and much of the Southern Ocean.

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

A comparative analysis of cell death signalling in RNA and DNA virus infections and potential inhibitory strategies

open access: yesThe FEBS Journal, EarlyView.
RNA and DNA viruses can manipulate host cell death through various mechanisms. RNA viruses (H1N1, SARS‐CoV‐2) induce acute apoptosis, necroptosis, and pyroptosis to promote rapid viral transmission and epithelial barrier damage. In contrast, DNA viruses (HSV‐1, EBV) regulate these mechanisms to sustain a lytic‐latency cycle, evade immune response and ...

Breaking the ice: multiple origins of ice‐binding/antifreeze proteins

open access: yesThe FEBS Journal, EarlyView.
Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for
