Differences in Siderophore Production During the Growth of Phytoplankton in Southern Ocean Incubation Experiments Under High‐ and Low‐Iron Conditions

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Experiments performed in the Southern Ocean under low‐ and high‐iron conditions showed that the heterotrophic bacteria community produced distinct iron‐binding compounds called siderophores, depending on the environmental conditions, despite similar bacteria communities being present in each experiment.

Prokaryotic Novelty and Metabolic Diversity in the Tagoro Shallow Hydrothermal System (Canary Islands, Spain)

Environmental Microbiology, Volume 28, Issue 9, September 2026.
Hydrothermal activity at the Tagoro submarine volcano shapes distinct epipelagic and benthic prokaryotic communities. Microbial diversity decreases towards vent sources, yet novel taxa dominate and potentially contribute to iron, nitrogen, sulphur and methane cycling in this shallow hydrothermal system with high unexplored microbial diversity ...

Global Patterns, Drivers and Conservation Gaps of Freshwater Crabs: From Species Richness to Phylogenetic Diversity

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim Freshwater crabs are ecologically vital benthic macroinvertebrates that sustain freshwater ecosystem functions, yet their limited dispersal and fragmented habitats make them vulnerable to human disturbance. Current conservation assessments for freshwater crabs remain incomplete, as most studies focus on species richness while neglecting ...

Dolomitic Microfossil Preservation in a Cryogenian Microbial Reef, Arkaroola (South Australia)

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Microbial dolostones that now form the Arkaroola reef, northern Adelaide Rift Complex, and were deposited during the Cryogenian interglacial period, display a wide range of meso‐scale stromatolite morphotypes in outcrop. Microcharacterisation involving optical microscopy, combined scanning electron microscopy and energy dispersive spectroscopy

Uranium Isotope Evidence for Persistent Global Ocean Anoxia Across the Ediacaran–Cambrian Transition in Siberia

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT The enigmatic Ediacara biota represents Earth's earliest example of macroscopic, complex life, yet the driving forces promoting their mid‐Ediacaran evolution and subsequent extinction across the Ediacaran–Cambrian boundary remain speculative. If these were true animals requiring oxygen for aerobic respiration, their rise has often been linked ...

Widespread Association of Ciliates Colonizing Gills of Shrimps Inhabiting Vents and Seeps Across the Pacific Ocean

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Bacterial symbiosis is well‐documented in chemosynthesis‐based ecosystems, but associations with microeukaryotes remain overlooked. In this study, using scanning electron microscopy and 18S rDNA barcoding, we investigate the presence, diversity, and biogeographic patterns of ciliate epibionts associated with two deep‐sea caridean families ...

Significant Imbalance Between Human Activities and Ecosystem Services in the Tibet Autonomous Region of China: Evidence From an Improved Coupling Coordination Degree Model

Land Degradation &Development, Volume 37, Issue 14, Page 10255-10271, 30 August 2026.
ABSTRACT Maintaining balanced interactions between humans and ecosystems in plateau regions is critical to achieving global sustainable development. However, existing methodologies are insufficient to fully elucidate the complex coupling and coordination relationships between human activities and ecosystems, as well as the sustainable development ...

We're in Hot Water Now: Hydrothermal Vents

In this lesson students will access a link to another site to learn about the processes that drive geysers, which are roughly analogous to hydrothermal vents.
