Role of extracellular carbonic anhydrase in the polar diatom Fragilariopsis cylindrus
New Phytologist, EarlyView.Summary Diatoms are major primary producers in productive polar oceans, where cold temperatures and high CO2 solubility raise questions as to whether they rely on the CO2‐concentrating mechanism (CCM) to saturate photosynthesis. Knowledge of CCM function will help better predict the sensitivity of diatom primary production to warming and acidifying ...

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae
New Phytologist, EarlyView.Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Plants synthesize ergothioneine, showing a link to abiotic stress
Plant Biology, EarlyView.Various plants possess ergothioneine biosynthetic genes and can synthesize this antioxidant, where increased EGT levels under abiotic stress conditions indicate protective functions. Abstract Ergothioneine (EGT) is a sulphur‐containing histidine derivative and a potent antioxidant that exhibits beneficial effects on human health.

Microcystins in components of twelve New Hampshire lakes of varied trophic status [PDF]
, 1999 Cyanobacteria toxins, called microcystins (MCs), were found in components of twelve, stratified New Hampshire (USA) lakes of varied trophic status during the summer of 1998.

Restoration Ecology, EarlyView.Restoration of coastal dunes following tropical storm events often requires renourishment of sand substrate dredged from offshore sources, although dredging has well‐described negative ecological impacts and high economic costs. As a potential solution, recycled glass sand (cullet) made from crushed glass bottles has been proposed as a potential ...

Tracking environmental trends in the Great Bay Estuarine System through comparisons of historical and present-day green and red algal community structure and nutrient content [PDF]
, 2011 Monitoring macroalgae populations is an effective means of detecting long term water quality changes in estuarine systems. To investigate the environmental status of New Hampshire’s Great Bay National Estuarine Research Reserve, this study assessed the ...

Restoration Ecology, EarlyView.Abstract Introduction Natural recovery of disturbed marine ecosystems can take years, mainly because long‐lived, functionally important species are lost. To regain ecosystem services, the focus of estuarine restoration is shifting from biodiversity metrics to functional restoration.
