Boreas, EarlyView.This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Boreas, EarlyView.Bioerosional scars made by limpets (Patella) on a cliff in Co. Antrim, Northern Ireland, indicate a Mid‐Holocene RSL of +7.8±0.55 m relative to local mid‐tide level today. This is higher than previous empirical data for the region and extrapolated levels from raised shorelines in Scotland but consistent with some recent GIA models.

Turbulent mixing beneath an undular bore front [PDF]
, 2008 In macro-tidal estuaries, a tidal bore may form during spring tide conditions when the flood tide is confined to a narrow channel. Most field occurrences showed well-defined undulations behind the leading wave, that is an undular bore process.

Integrating ecological feedbacks across scales and levels of organization
Ecography, EarlyView.In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

PFAS from a Discrete‐Event Terrestrial Source Migrates with Groundwater to Intertidal Seepages
Groundwater, EarlyView.PFAS is conveyed to the coastal intertidal zone from sources across the terrestrial landscape. Discharge of PFAS into the coastal ecosystem is complicated in space and time by the ongoing bi‐directional exchange of terrestrial groundwater and ocean water driven by tidal pumping within discharge areas.

Turbulence measurements in tidal bore-like positive surges over a rough bed [PDF]
, 2013 A sudden rise of the water depth in an open channel flow creates a surge propagating in the channel called a positive surge. Positive surges can be observed as natural phenomena when a spring tide enters a funnel-shaped estuary under appropriate tidal ...

Journal of Phycology, EarlyView.Abstract Despite the importance of the seasonal timing of events in the life cycle for understanding population dynamics, we lack information on the phenology of most macroalgal species. The red macroalga Gracilaria vermiculophylla has become common in both hard‐ and soft‐bottom habitats following its invasion throughout the Northern Hemisphere.

Journal of Phycology, EarlyView.Abstract The invasion of the red macroalga Gracilaria vermiculophylla provided an opportunity to investigate the influence of benthic habitats on the reproductive mode, population structure, and colonization dynamics in haploid‐diploid life cycles.

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis
Journal of Periodontal Research, EarlyView.Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...
