Novel Hydrurus species (Chrysophyceae) and their adaptations to high‐altitude European and Arctic snowfields

Journal of Phycology, EarlyView.
Abstract Colored snow caused by green algae (Chlorophyceae) is well known, but melting snowpacks can also harbor golden‐brown blooms consisting of Chrysophyceae. We collected 14 samples of cryoflora in the Austrian and Swiss Alps, the High Tatras in Slovakia, and in Arctic Svalbard. Eight laboratory unicellular flagellated strains were established from

Evaluation of combined root exudate and rhizosphere microbiota sampling approaches to elucidate plant–soil–microbe interactions

New Phytologist, EarlyView.
Summary Deciphering the root exudate‐driven interplay between plants and the rhizosphere microbiota is essential for understanding plant adaptation to the environment and future‐proofing crop production. However, sampling root exudates and rhizosphere soil remains challenging due to the low throughput and destructive nature of the process.

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...
