Do you have new stoichiometric research to share? If so, consider submitting an abstract to our special session SS027. Abstract deadline is Nov 24 (yes, under a week!). Can't wait to see people in Montreal, to spill the tea on all things ratios. @helenaklip.bsky.social #ASLOSIL26

The glaciers of the Sierra Nevada have probably existed since the last Ice Age more than 11,000 years ago. The remnants of these glaciers are expected to disappear in the coming decades as temperatures continue to rise.

This is depressing. In my lectures on Freshwater Security @uclgeography.bsky.social, I used to teach about what should be learned about the Aral Sea, as water levels in lake Lake Urmia declined.

To see another salt lake disappear is awful for impact on biodiveristy and human livlihoods. #geosky

The Mazama newt is found in only one place in the world: Crater Lake. But this tiny amphibian is disappearing, due to invasive crayfish taking over its habitat. We’ve teamed up with the National Park Service and High Desert Museum to give this rare newt-y cutie a fighting chance.

Nice new work out in Ecology Letters by Ozersky and colleagues, showing that high latitude lakes will likely feel the greatest impacts of warming winters. onlinelibrary.wiley.com/doi/10.1111/... #winter #limnology
Impacts of Changing Winters on Lake Ecosystems Will Increase With Latitude
Climate warming is particularly strong in winter and at high latitudes, driving changes in lake ice and snow cover. Using simple models, we show that the interaction between ice duration and seasonal....

As winters warm, small lakes at high latitudes are suffocating. In a recent @pnas.org commentary, #NASmember James Elser and Helena C. L. Klip explain how reduced ice is cutting off oxygen supply, threatening aquatic life in shallow lakes. Read more: www.pnas.org/doi/10.1073/...

For decades, the biomedical industry has relied on a compound in horseshoe crab blood to protect medical equipment from contamination, saving untold human lives.

But conservationists say modern medicine’s dependence on this bloodletting is upending a globe-spanning ecosystem.
These crabs probably saved your life. Can we save theirs?
The medical world relies on horseshoe crab blood in the production of vaccines and equipment. A synthetic is available, but companies have been slow to adopt it.

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.

The ‘king of poisons’ is building up in rice.

Rice feeds more than half of the world’s population. Climate change is loading the beloved grain with arsenic, creating a “scary” health burden.

A quarter of Earth and more than 50% of its population are affected by water scarcity each year. Considering only surface and groundwater can underestimate the problem, as insufficient soil moisture and water quality are also key factors. In PNAS: www.pnas.org/doi/10.1073/...
