this is an actual town in Sicily called Centuripe

Hope everyone has a magical winter solstice 🖤

Banjul, The Gambia

NASA's Terra spacecraft shows Banjul, the capital of The Gambia; it is located on St. Mary's Island, where the Gambia River enters the Atlantic Ocean in western Africa.

If you are interested by those #photometeor, here is an amazing #picture of the #Sun with so many of them, as annotated on the second picture.

They are the result of #Sun's reflections and refractions into tiny ice crystals (in clouds or fog) of various shapes, which act as mirrors or prisms.

Farm Service Administration photos of erosion in Mississippi during the Great Depression. Deforestation and cotton cultivation had exposed and depleted the state's incredibly fertile soil, much of which had been deposited by the meandering Mississippi River over millennia.

Groundbreaking of NACA's (later NASA's) annoying wind tunnel happened on this sad day in 1939. Russell Robinson supervised it.

I have not had a quiet day since.

Global field observations of tree die-off reveal hotter-drought fingerprint for Earth’s #forests.

Earth’s forests face grave challenges in the #Anthropocene, including hotter droughts increasingly associated with widespread forest die-off events.

Frequency of the observed mortality-year climate conditions strongly increases nonlinearly under projected warming.

Forests are dying due to #climate change.

#CAD for Gardeners
🧵…

This world needs more wildlife, more wildlife gardens, more sustainable food.

🐛🌳🧑‍🌾

I’m a #wildlife and food #ForestGarden #designer, and I use #CAD. A lot.

CAD (Computer Aided Design) is a really useful tool for #GardenDesign, because you can figure out #tree spacing and quickly calculate lengths for #windbreak hedges & areas for #GroundCover & #NativePlant #WildFlowers

A plan also communicates ideas with partners, and documents plants to help with maintenance

This is why boats head to the Canary Islands to sail West to the Americas, and return via Bermuda and the Açores: the Trade winds.

I show this bug every year to my intro entomology students to see if they can figure out what body part all that undulating spiny weirdness is.

Heteronotus sp. treehopper, Ecuador.

I just finished a bowl of cashews and thought I'd share a pic of a cashew apple that I got to eat in Costa Rica. The yellow part is a pseudofruit (because it lacks seeds) and is absolutely delicious. Note that you should wash your hands if you touch the shell (the actual fruit) because it contains urushiol just like poison ivy (both are in the Anacardiaceae). The seeds have this chemical, too, but it's removed by cooking. #fruit #nuts #botany #cashew #plants.

This book is hard to find (and rather expensive when found) but the drawings are gorgeous.

New here on Mastodon. My group at University of Virginia studies #devbio and #evodevo of adult traits in #zebrafish and other species, mostly pigment pattern and scales. Also work on skeleton, postembryonic stem cells, behavior, natural history, other topics. Always looking for new weird stuff.

Following on from the #30DayChartChallenge, I've written (another) blog post comparing my favourite R packages for making maps and visualising spatial data in R!
