Seafloor mapping in a high Arctic fjord (Grise Fiord) revealed many submarine landslides triggered by iceberg groundings, coastal debris flows and delta collapses. The dating of three of them suggests that they occurred at past climate transitions. ABSTRACT Arctic fjords are experiencing rapid environmental change driven by amplified high‐latitude ...

Studies of Encystment and Germination in Azotobacter Vinelandii [PDF]
Light and electron microscopy were employed to study the encystment and germination processes in Azotobacter. Data obtained from frozen-etched replicas and chemically fixed cells revealed that as encystment occurs, the cells become rounded, and lose ...

Free‐living amoebae may provide an underrecognised environmental niche for Helicobacter pylori, supporting its intracellular persistence, morphological plasticity, and protection from environmental stress. These interactions could facilitate prolonged survival in aquatic and food‐associated environments and contribute to potential waterborne or ...

Encystment of Acanthamoeba and Evaluating the Biobus Program
Acanthamoeba are ubiquitous protists that play an environmental role in regulating microbial diversity; they also occasionally cause infections of the eye (Acanthamoeba keratitis) and brain (granulomatous amoebic encephalitis).
