I still have my (many) reservations about ocean alkalinity enhancement. But I'm very happy to see this sort of study about it, looking at how it may affect plankton.
Also, the title is brilliant.

How do tropical #trees deal with droughts? The answer is published today in @science.org

So far the plan has seen minimal pushback from Congress.

Nitrogen deposition and climate drive plant nitrogen uptake while soil factors drive nitrogen use efficiency in terrestrial ecosystems Abstract. The role of plants in sequestering carbon is a critical component in mitigating climate change. A key aspect of this role involves plant nitrogen (N)Β uptake (Nup) and NΒ use efficiency (NUE),...

How much nitrogen are plants taking up from the soil? How efficient are they at building biomass with it? Are models doing a good job assessing it? Find your answers in our last publication (open access!): esd.copernicus.org/articles/16/...

More Than Just For Cleaning: The importance of Sponges through the Eyes of BΓ‘slavi CΓ³ndor LujΓ‘n and Her Students In this feature, we spoke with some of BΓ‘slavi CΓ³ndor LujΓ‘n's students to learn more about their work exploring sponges, one of the ocean’s most overlooked but ecologically vital organisms.

β€œSponges are among the least studied organisms in Peru, along with many others that at first glance seem to have no significant importance to humans. As a result, the biodiversity of our country is highly undervalued”

Herring spawned poleward following fishery-induced collective memory loss - Nature A critically low abundance of older herring due to age-selective fisheries resulted in an approximately 800-km poleward shift in main spawning.

have you heard about the fish that forgot its migration?

herring used to feed in northern Norway and migrate south (>1000km) to spawn

a few years ago they abruptly stopped doing that

authors think older adults were overfished & didn't "teach" younger fish to migrate!

Marine heatwaves as hot spots of climate change and impacts on biodiversity and ecosystem services Nature Reviews Biodiversity, Published online: 07 July 2025; doi:10.1038/s44358-025-00058-5Marine heatwaves (MHWs) have become more intense and widespread globally, affecting species, ecosystems and people. After summarizing how and why MHWs are changing, this Review explores these impacts and their underlying mechanisms, highlights knowledge gaps and considers opportunities to mitigate the effects of MHWs.

Salt marshes that look healthy aboveground may be losing biomass in their roots, according to a study of spartina marshes on the coast of Georgia between 2014 and 2023. This below-ground biomass loss could be a harbinger of salt marsh loss. In PNAS: www.pnas.org/doi/10.1073/...

Biomass and Biodiversity Were Coupled in Earth's Past - Eos Measuring shells and skeletons encased in thousands of limestone samples has revealed that the sheer amount of living stuff in Earth’s oceans changed alongside the diversity of organisms.

Data on how ecosystems evolve over geologic time may be key to understanding modern-day ecosystem changes. A study of marine biomass over the past 541 million years gets scientists one step closer.
