Aldo Leopold was born OTD in 1887. “We abuse land because we see it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect.” #HpBio #HistSTM 🌎 #philsci #STS 🧪

Played my first game of Finspan. The mechanics are a bit more fun than Wingspan, but, like Wingspan, it lacks any significant players interaction.

“Retrofitting something as seemingly mundane as a culvert can have vast ecological & cultural ramifications.” @seattlebryn.bsky.social speaking my language! Also note improved fish passage preventing wildlife collisions. Better culverts work for all. #roadecology magiccanoe.org/salmon-rebou...

Federal fisheries officials on Monday rejected a bid to designate West Coast Chinook salmon as threatened or endangered under the Endangered Species Act. The Center for Biological Diversity, says it is considering a legal challenge. #cawater www.sacbee.com/news/politic...

White sturgeon are highly prized for their eggs, which are made into caviar. With poaching rampant and populations dropping, can California’s sturgeon survive? #cawater mavensnotebook.com/2025/12/10/m...

When a meal fights back! I’ve only gotten distant looks at Yellow-crowned Night-heron adults, delighted to find one close! It’s trying to eat a crab but the crab’s got its beak pinched. Super compressed video quickly moved to my phone from my camera (sorry!) just too excited to wait to share

sometimes I do field work in the most gorgeous water (Harrison river, BC) and you can see the sturgeon swim away forever 🥹 this is a nice close up of the scutes that cover sturgeon for protection, they have several rows of these bony plates that can be really sharp! #sturgeonsaturday 🧪👩🏻‍🔬🌎🌐

Wow! Wolves are raiding crab traps for fish by pulling the buoy line until the trap comes ashore and then shredding it. Someone still needs to teach these proto-tool users how to repair, maintain, and deploy the nets, but they have the critical step down! 🦊🐟🌎 www.nbcnews.com/world/canada...

From Thomas MacGuane’s collection “Gallatin Canyon”:

did you know we had ~80 huge sturgeon die this year (that we know of) in 2 BC rivers? These deaths occurred during the summer when the sockeye salmon were returning sturgeon eat many salmon at once, and this may be overloading their metabolic capacity during hot summers 😱 #sturgeonsaturday 🧪👩🏻‍🔬🌎🌐

Vaquitas "hanging on" is a fair description. Describing this as a modest increase is not following the science. From the survey report summary - "There is too much uncertainty in visual estimates to make strong conclusions about a trend in vaquita numbers..." more quotes to come 🐳🌍🦑 1/2

Grateful to spend two days on the Klamath watching chinook, liberated by dam removal, return to streams from which they’d been precluded since the Titanic sank. Fish are everywhere, in numbers that stagger the mind & locations that biologists figured would take years to repopulate. Too beautiful.

"The only efficient use of generative "AI" I see is helping to meet basic and excessive administrative burdens (e.g. filing unimportant progress reports). Maybe we should just reduce those rather than invest in a technology that can write a C+ essay."

Many aspects of 🏙️ city life are sustained by nature, preserving city ecosystems is important not only for global biodiversity but for local human quality of life.

The Trump admin says CO can't get wolves from Canada bc of their ESA status. Instead, CO must get them from US Rocky Mountain states, most of which have declined to participate in reintroduction. The move effectively cancels the program. But does this mean if wolves are delisted, all bets are off? 🌎

My heart was jubilant while reading this story this morning - more than 100 Chinook salmon have passed the former Klamath River dam sites as well as the fish ladder at Klamath Lake and are naturally spawning in Oregon headwaters for the first time in over a century! 🐟🧪🌎 www.opb.org/article/2025...

Next time a student asks, "Why do we need to learn statistics?" Just put this up and sit down silently.

Behold the striking colors of the blue-spotted stingray! Its bright spots are a warning to onlookers that it's venomous—& if its colors aren’t enough to ward off foes, it’s equipped w/ a tail that can inject a lethal dose of toxins. Photo: Derek Keats, CC-BY-2.0, Wikimedia Commons

None of this needs to happen. We are watching an intentional destruction of scientific and engineering expertise.
