Thanks! We’re glad this funny title can catch people’s attention.

Thanks! We kind of unintentionally mixed Taiwan’s recent pun trend into this American idiom.😂

Death and Taxus: the contribution of mechanical damage to the multiple factors associated with Taxus brevifolia mortality - Ecological Processes Background Recent increases in tree mortality are often attributed to climate, but climate extremes may just be the last of many stressors that have unfolded over many years resulting in tree death. P...

We published! I am very excited to share this story. Our study shows that Taxus mortality is not caused by competition. Many deaths began with mechanical damage from fallen trees more than a decade ago, starting a long decline that led to recent mortality.

Trump wants to cut research centers like the one in this PNW forest Congress will take up Trump's proposed budget cuts, which target 26 long-term ecological research centers like the H.J. Andrews Experimental Forest in Oregon.

Always a pleasure to see others recognize the value of our network.

"[The LTER Network] has enabled scientists to get answers that have led to key policy decisions, from amending the Clean Air Act to prevent acid rain to preserving old-growth forests."

A map of strikes by India on May 7. The text reads: "Where India Struck Pakistan on Wednesday. Officials and witnesses said that at least two Indian aircraft had crashed after India struck Pakistani targets, escalating the conflict between the nuclear powers."

India said early Wednesday that it had conducted several airstrikes on Pakistan after 26 civilians were killed in a terrorist attack in Kashmir. But evidence is growing that the Indian forces may have taken heavy losses during the operation. nyti.ms/4dbIwei

See you next year! I am going back to my warm country.

Taiwan's 30-Year Average Temperature and Precipitation Pattern

This map, inspired by @tterence.bsky.social, uses climate data from Climate AP to illustrate Taiwan's 30-year distribution of temperature and precipitation.

I used Arctic ocean DEM data to sneak in some marine DEM, mapping out the land areas. By stacking the same dataset three times, I was able to highlight the ocean, flat area, and mountainous regions.

Yeah! It is!

The video seems like using ggridges package to draw the ridge line, not rayshader.

Oh gosh man! How did you do that?

Love it!

Having not sketched in years, I simply created a basic map of Mudou Island in Penghu, Taiwan.

My instruction to ChatGPT 4o is : The Taiwan map should have a very old-fashioned style, evoking a sense of heavy political pressure from 1945-1990. Then, generate and display the map here.

A dumpster AI! I'd rather write the code myself. If any information is incorrect, that's not on me!
