More news about the potential collapse of an ocean current, the Atlantic Meridional Overturning Circulation (AMOC) which transfers heat from the tropics to northern Atlantic, giving Europe a much milder climate, controls plankton productivity, and importantly also generates deep ocean circulation by sinking cold dense water.

Anyway here's a California poppy, Eschscholzia californica, at the Antelope Valley California Poppy Preserve earlier this spring

Terrible backlit photos of bird this morning feeding at insects at corner of the windows. Quite active and hard to see well, but still very sure it is a female american redstart from the very distinct yellow bands on the tail with a very dark tip. #birds #birdsofmastodon
AI would have done the patterns slightly wrong, relative to the mathematically perfect patterns that nature produces deterministically. https://ecoevo.social/@danmccullough/114698742002848774
Monday I ran the Boston Marathon, and I'm glad I did but boy, was it a long time getting there

With a record heatwave starting tomorrow, #ShowYourStripes day is timely.🥵
The #GreatLakes have helped to moderate warming, but even in southern Ontario we see a clear pattern of significantly increased warming during the last 25 years.
It was an interesting and fulfilling experience to be part of the @… working group on Winter Science in the Great Lakes. There are so many nuances to how #ClimateChange and development are likely to impact ice and seasonality in the

A lot to celebrate in the lab at the end of the school year — students at commencement, and a campus award for our paper presenting a reconstruction of Joshua tree flowering activity since the early 20th century

Our partners at the NOAA Great Lakes Environmental Research Laboratory have found cyanobacteria microcystin toxins in the western basin of Lake Erie April 28, far earlier this year than ever before. The season starts earlier and lasts longer due to #ClimateChange.
CSUN campus squirrels are spoiled rotten, not the least because we have a largely un-harvested orange grove

A new paper projecting Joshua tree habitat under future climate based on incredibly high-resolution distribution data, from Joshua Tree Genome Project collaborators at USGS. They estimate up to 80% loss of suitable habitat by 2100 under the worst-case climate scenario.

The proposed sell-off of federal lands in the Senate budget bill includes a LOT of Joshua tree habitat—the trees grow in some of the largest areas of undeveloped land in the lower 48 states
The place where eastern and western Joshua trees hybridize, north of Creech AFB, is included

Super cool system where we did fieldwork some year ago.
Kudos for mentioning trouble with the Niagara Board of Control. 🏅

Plankton is fundamental to the functioning of aquatic #ecosystems. An example was seen in the 2013 deaths of #Florida bottlenose dolphins. Dense harmful phytoplankton

Randall Munroe (of xkcd fame) posted about an analysis done by David R. Hagen related to his "missing 11th" comic. Great read, which includes some nice statistical analysis, but more interestingly, bias and artifacts.

The new Surface Water and Ocean Topography (SWOT) satellite is crazy accurate. It can measure ocean altimetry to a mm, imaging internal waves and small sub eddies (rotating mixing zones). Tiny changes in height happen when water swirls (try it in a sink) with greater height at the edges due to centripetal force. These may be even more important for temperature &a…

I missed this in the midst of everything else last week, but of course the Trump Administration has killed the questions on sexual orientation and gender identity in NSF's Survey of Earned Doctorates, which were only put in place after YEARS of effort by advocates

Got a new op-ed in LNC/LancasterOnline this morning, on the importance of the curiosity-driven science the National Science Foundation is supposed to support
"For every Thermus aquaticus there are hundreds of scientific projects that end in nothing more than a peer-reviewed research article and some fond memories of fieldwork. But we need those hundreds of curiosity-driven studies to find that one lucky, world-changing discovery."
Honestly, good for these folks
