A Genomic Catalog of Migratory Microbiomes from Wild Birds across China's Habitats
Advanced Science, EarlyView.ABSTRACT Migratory birds play an important role in the spread of antimicrobial resistance (AMR); however, gaps in surveillance data from vital regions along migratory flyways across China limit the detection of emergent threats. Here, we assembled 340 metagenomes from 52 bird species covering 11 provincial administrative districts in China, presenting ...

Geophysical Research Letters, 2018 Although the Southern Ocean is thought to account for a significant portion of the contemporary oceanic uptake of carbon dioxide (CO2), flux estimates in this region are based on sparse observations that are strongly biased toward summer. Here we present

Advanced Energy and Sustainability Research, EarlyView.Combinatorial Nb‐doped TiO2 wafers with a lateral dopant gradient enable rapid mapping of how phase composition and defects influence photocatalytic activity. Optimized Nb content generates mixed anatase–rutile phases together with beneficial Ti3+ and oxygen vacancy defects, boosting dye‐degradation efficiency fivefold.

Southern Ocean Biological Pump Role in Driving Holocene Atmospheric CO2: Reappraisal
Geophysical Research LettersChanges in Southern Ocean biological pump efficiency are frequently invoked as a source of glacial/interglacial CO2 variability. It was recently suggested that Southern Ocean biological pump weakening also contributed to Holocene CO2 increase.

Import Wheat Tenders and the Effects of the Russian Invasion
Agribusiness, EarlyView.ABSTRACT Risk and volatility for many commodities escalated sharply following the Russian invasion of Ukraine, creating numerous uncertainties for trading firms and importers. The purpose of this study is to analyze the bidding behavior in Egyptian wheat import tenders in the pre‐ and post‐invasion periods.

, 2017 This chapter highlights how satellite altimetry has helped to illuminate the circulation and dynamics of the Southern Ocean and shows how altimetry has been used to identify the position of the Antarctic Circumpolar Current fronts. It describes the use of altimetry to characterize the four-dimensional temperature and salinity structure of the Southern ...
