Observations of a puma predation on endangered California condors: Implications for species recovery
Reintroduction of endangered species is wrought with many challenges, but one often overlooked challenge is the threat of predation of naïve individuals. Individuals lacking the insight to avoid pred...

CDFW wrapped up wolf capture & collar operations recently in northern CA resulting in a record 12 wolves now outfitted w/ satellite collars. Collar data provides info to understand diet, dispersal, pack formations & help mitigate conflicts w/ ranchers

The one thing I do miss on X and now seemingly here is the absence of amazing, novel and interesting papers that everyone is publishing. I realize things are hard right now but beacons of positivity and hard work help lift us up, as these are the efforts we pour our lives into.

I just got a report that a terminated employee from another agency got their job back after replying to the termination email with their good perf appraisal.
If you are still connected, might as well try. It makes for good documentation if nothing else.
Let me know. So far only this one anecdote.

Turbulence moving through rock over hundreds of year withering down and creating a path once over now through the rocks, the sun peering through the pines, the roar of water cascading down behind me from Bassi Falls. A gorgeous Saturday in the woods and perfect way to end November.

Species distribution models (SDMs) are useful tools in ecology and conservation biology. As the name implies, SDMs are used to estimate species presence or abundance across geographic space and throug...

My concern with majority scientists removing themselves from X and only being here is the science and studies may not reach the the a large chunk of the general public as they have in the past.
