Heterogeneous long-term changes in larch forest and shrubland cover in the Kolyma lowland are not captured by coarser-scale greening trends by Heather Kropp, Michael M Loranty, Howard Epstein, Gerald V Frost, Adam Koplik, Logan T Berner

“…The expansion of tall shrubs and trees can alter ground thermal regimes and soil moisture impacting permafrost and biogeochemical cycling. Changes in shrub and tree cover can be difficult to characterize with limited in-situ observations and moderate/coarse resolution satellite imagery, thereby posing challenges in disentangling changes in vegetation growth from shifts in vegetation composition. …”

Arsenic and Antimony in Hydrothermal Plumes from the Eastern Manus Basin, Papua New Guinea by Zhigang Zeng, Xiaoyuan Wang, Haiyan Qi, Bowen Zhu

“…As and Sb with Mn showed a positive correlation (R2>0.8, p<0.05), and the distributions of As and Sb within the hydrothermal plume are not controlled by particle adsorption or biogeochemical cycles, suggesting that As and Sb, like Mn, can be used to detect and describe the characteristics of hydrothermal plumes in seawater environment. …”

Assessing Microbial Diversity in Páramo Soils (Multistrategy Analysis): Effects of Potato Farming and Livestock Grazing in Nevados National Natural Park, Colombia by Lizeth Manuela Avellaneda-Torres, Tomás León Sicard, Edlin Guerra Castro, Esperanza Torres-Rojas

“…Changes associated with potato farming and livestock grazing on microorganisms of Páramo soil of the Nevados National Natural Park (Nevados NNP) were assessed by (1) determination of physical and chemical properties (physicochemical matrix) and enzymatic activities associated (enzymatic activity matrix) with different biogeochemical cycles (C, N, and P); (2) microbial community functional diversity via evaluation of functional groups associated with carbon, nitrogen, and phosphorus cycles using cultivation-dependent techniques (arable functional group matrix and most probable number matrix); and (3) microbial diversity using cultivation-independent techniques that employ the hypervariable V5–V6 region of the 16S rRNA gene and pyrosequencing (16S-454 genus matrix and 16S-454 OTU matrix). …”

Tracing the origins and transformations of fluorescence dissolved organic matter within western and eastern Greenland’s shelves: a comparative study by Monika Zabłocka, Piotr Kowalczuk, Joanna Stoń-Egiert, Elena Terzić, Elena Terzić, Evanthia Bournaka, Artur P. Palacz

“…Differences in the composition and spatial distribution of Fluorescent Dissolved Organic Matter (FDOM) between western and eastern Greenland shelf waters reflect the interplay of distinct regional environmental drivers-such as glacial meltwater inputs and stratification effects – which shape local DOM processing and biogeochemical cycles. These contrasts provide unique opportunity to understand how Arctic coastal system responds to climatic changes. …”

Genome-resolved year-round dynamics reveal a broad range of giant virus microdiversity by Yue Fang, Lingjie Meng, Jun Xia, Yasuhiro Gotoh, Tetsuya Hayashi, Keizo Nagasaki, Hisashi Endo, Yusuke Okazaki, Hiroyuki Ogata

“…We argue that greater microdiversity of viruses likely enhances adaptability and thus survival under the virus–host arms race during prolonged interactions with their hosts.IMPORTANCERecent genome-resolved metagenomic surveys have uncovered the vast genomic diversity of giant viruses, which play significant roles in aquatic ecosystems by acting as bloom terminators and influencing biogeochemical cycles. However, the relationship between the ecological dynamics of giant viruses and underlying genetic structures of viral populations remains unresolved. …”
