Complexity yields simplicity: The shifting dynamics of temperate marine ecosystems
(University of Tsukuba) Researchers from the University of Tsukuba find that the combined effects of ocean warming and acidification in temperate marine ecosystems are resulting in a loss of kelp habitat and a shift to a simple turf-dominated ecosystem. Such changes will lead to a loss of the ecosystem services provided by productive macroalgal forests or tropicalized coral-dominated reefs. These results highlight the need for reductions in greenhouse gas emissions. (Source: EurekAlert! - Biology)

Kelp for corn? Illinois scientists demystify natural products for crops

‘A Year Full of Emotions.’ What Kids Learned From the COVID-19 Pandemic
Too many young generations have been shaped by the global crises they faced—Depression-era poverty, Cold War nuclear fears. Add to them the COVID generation. The virus itself may typically go easier on kids than it does adults, but the mind of a child is another thing. It’s dependent on certainty, safety, the comfort of routine. Take all of that away—shutter schools, keep grandparents at a distance, cancel summer camps—and kids suffer. But as the following lightly-edited stories from young people show, they also grow and learn, gain maturity and wisdom. The virus has been tough; plenty of kids, it t...

How Industrial Fishing Creates More CO2 Emissions Than Air Travel
It’s been well established by now that the agricultural systems producing our food contribute at least one fifth of global anthropogenic carbon emissions—and up to a third if waste and transportation are factored in. A troubling new report points to a previously overlooked source: an industrial fishing process practiced by dozens of countries around the world, including the United States, China, and the E.U. The study, published today in the scientific journal Nature, is the first to calculate the carbon cost of bottom trawling, in which fishing fleets drag immense weighted nets along the ocean floor, scraping ...

(University of California - Santa Cruz) Satellite imagery shows that the area covered by kelp forests off the coast of Northern California has dropped by more than 95 percent, with just a few small, isolated patches of bull kelp remaining. Species-rich kelp forests have been replaced by 'urchin barrens,' where purple sea urchins cover a seafloor devoid of kelp and other algae.

Keystone predators govern the pathway and pace of climate impacts in a subarctic marine ecosystem
Predator loss and climate change are hallmarks of the Anthropocene yet their interactive effects are largely unknown. Here, we show that massive calcareous reefs, built slowly by the alga Clathromorphum nereostratum over centuries to millennia, are now declining because of the emerging interplay between these two processes. Such reefs, the structural base of Aleutian kelp forests, are rapidly eroding because of overgrazing by herbivores. Historical reconstructions and experiments reveal that overgrazing was initiated by the loss of sea otters, Enhydra lutris (which gave rise to herbivores capable of causing bioerosion), an...

Cascading social-ecological costs and benefits triggered by a recovering keystone predator
Predator recovery often leads to ecosystem change that can trigger conflicts with more recently established human activities. In the eastern North Pacific, recovering sea otters are transforming coastal systems by reducing populations of benthic invertebrates and releasing kelp forests from grazing pressure. These changes threaten established shellfish fisheries and modify a variety of other ecosystem services. The diverse social and economic consequences of this trophic cascade are unknown, particularly across large regions. We developed and applied a trophic model to predict these impacts on four ecosystem services. Resu...
