Summary: In this study, the recovery of viral diversity from marine samples using long-read sequencing was explored. The results showed that a significant portion of marine viral diversity was directly recovered by PacBio circular consensus sequencing (CCS) reads, with some sequences not being detected in the short- and long-read assembly. Additionally, the hybrid assembly of long and short reads improved the length and host assignment of the viral sequences.

Summary: This study found that disturbance level determines the importance of stochastic relative to deterministic changes in ecosystem components, predefining the pattern of post-disturbance ecosystem succession. It was also observed that nitrogen addition reduced the importance of stochastic changes, leading to a quadratic relationship with disturbance level. Monitoring the importance of stochastic relative to deterministic changes in an ecosystem can help estimate disturbance levels, predict succession patterns, and propose disturbance-level-dependent strategies for restoration.

Summary: Oxygen-deficient marine waters known as OMZs or AMZs are common oceanographic features that host microorganisms adapted to low oxygen conditions. The metabolic interactions of these microorganisms drive biogeochemical cycles and impact nitrogen loss and trace gas production and consumption. With the expansion and intensification of oxygen-deficient waters due to global warming, studying microbial communities in these areas is important for understanding the effects of climate change on marine ecosystem functions and services.

Summary: Using Tara Oceans sampling, a global ocean cross-domain plankton co-occurrence network was identified and niche modeling was used to assess its vulnerabilities to environmental change. The results showed that the plankton interactome self-organized latitudinally into marine biomes and was more connected poleward. These findings provide baseline approaches to assess community structure and organismal interactions under climate scenarios, while identifying plausible plankton bioindicators for monitoring climate change in the ocean.

Summary: The study found that cold-water corals show changes in their microbiome, lower energy reserves, and decreased skeletal growth at warmer temperatures, while both species quickly lose their specific bacterial signature and experience reduced physiological activity followed by death at extreme temperatures. In addition, the corals' negative response to colder temperatures suggests they are living close to their thermal optimum in the Mediterranean Sea. The species-specific response to temperature change highlights the potential dramatic impact of global warming on deep-sea reef-builders and associated biodiversity.

Summary: The sediment cores from the Congo deep-sea fan show that the sediments are enriched in fatty acids and have a similar composition to the sediments from the Congo River. The limited reprocessing of the sediments during transit is likely due to tight interactions with mineral particles and rapid transfer. The combination of fatty acid profiles and geochemical proxies reveals that organic matter degradation is mostly limited to the oxic layer and there are distinct depositional dynamics between fine soil-derived particles and coarser higher plant detritus.

Summary: The Northern shoveler is a migratory bird that makes several stopovers during its spring migration to replenish energy reserves before reaching its breeding site. However, little research has been done on its diet during these stopovers. This study focused on the feeding habits of the Northern shoveler during its spring migratory stopover in the Marais breton wetland in France. The study found that the shoveler primarily feeds on microcrustaceans, Chironomidae larvae, Corixidae, Hydrophilidae larvae, and particulate organic matter, with the latter being a previously unknown food source.

Summary: Research on marine microbial communities is hindered by variation in seawater sampling protocols, making comparisons between studies difficult. To address this issue, the EuroMarine Open Science Exploration initiative (EMOSE) was developed to provide researchers with a dataset that incorporates different seawater sampling methodologies. The dataset revealed that the volume of seawater filtered did not significantly impact prokaryotic and protist diversity, but there were noticeable differences in alpha and beta diversity between size fractions and whole water samples. This study emphasizes the importance of considering methodological options when analyzing marine microbiome data.

Summary: This study used metagenomics to investigate the seasonal dynamics of vitamin B-12-related pathways and the functional diversity of associated microbial communities in the coastal NW Mediterranean Sea over 7 years. The findings revealed a succession of different organisms carrying distinct production pathways for vitamin B-12 metabolism in different seasons. Additionally, the study found that during years with environmental perturbations, organisms carrying vitamin B-12 synthesis genes were replaced by others with the same gene, thus maintaining the potential for vitamin B-12 production.
