I have an SDM joke, but I can't decide if it's worth telling.

As women in academia, having children can feel impossible. Talking about it makes us feel less alone The struggle is “balancing their careers not just with motherhood, but with what comes before: relationships and planning for a family,” these postdocs write

"The real issue wasn’t just.. preserving fertility. It was the systemic barriers—the ways the academic structure itself, with its relentless relocations, temporary contracts, and focus on individual achievement, makes planning for a family feel like an impossible luxury."

“The Sinixt people have always had that responsibility, and we've always felt that responsibility. There's just things that have stood in our way,” said Rich Whitney, the reservation’s senior wildlife manager, and a Sinixt tribal member."

Congress releases conferenced FY2026 Interior spending bill - The Wildlife Society The draft bill represents the next step in setting annual funding levels for key federal conservation programs

Higher proposed funding in congressional spending budget than the presidential (which zeroed out much natural resource funding, esp for #conservation and research work). Still proposed cuts here to tribal grants and climate adaptation sci centers; proposed increase to ecosystems mission area

I’ve been surprised at the opposition to more housing from purportedly progressive peoples. We’re renting in the lower rattlesnake and surrounded by a sea of anti-density signs :(

Montanans Are Making Space for Grizzlies Wildlife corridors and conflict prevention help keep bears safe

With federal protections for grizzlies under threat, grizzly bears in the Intermountain West will need more local support. In Montana, a growing cohort of residents is doing just that—helping communities in bear country coexist while making it easier for bears to traverse the landscape. 🌎

BREAKING: The first segments of border wall have gone up in the San Rafael Valley, south of Tucson, Ariz. Construction crews have drilled at least two wells and have turned the area, a corridor for jaguars, pronghorn, bears, mountain lions, ocelots, porcupines, into an devastating industrial site.

So excited to share this paper, lead-authored by newly-minted Dr. Andrew Dreelin from my lab and @andyjboyce.bsky.social's with you all! 🧪

There's this paradox about prairie dog towns - many birds seem to love them, but they attract a lot of predators.

Table S1. Plant genera included in the model, with justifications for inclusion.

Allium: Alliums produce large nutrient-dense geophytic bulbs that
represent a potential year-round food source for bears

Avena 

Camassia: Camassia produce large nutrient-dense geophytic bulbs that
represent a potential year-round food source for bears

Carex: Carex plants produce nutritious forbs during the green-up
season and nutrient-dense seed heads during reproduction

Prunus

Quercus: Oaks produce large flushes of highly nutritious and
calorie-dense acorns, generally during the autumn months

Rubus: Rubus plants produce large flushes of nutrient-dense fruits
between spring and fall, depending on the species and climate. They are eaten by black bears frequently in California and grizzly bears outside of the state. 

Vaccinium 


In addition to plants, we also modeled the distribution of
cutworm moths (of the family Noctuidae). These moths have
been shown to be important sources of protein and calories
for grizzly bears in the Rockies, especially in high-elevation
habitats [25], [53]. Lastly, we included Columbian blacktailed
deer (Odocoileus hemionus columbianus) and other
mule deer (Odocoileus hemionus), which are predicted to
be one of the main natural mammalian prey for California
grizzly bears. We did not include elk (Cervus canadensis),
as elk populations are generally small where they occur
throughout the state and do not occur in large numbers in
two-thirds of our study’s potential recovery areas.

I'm surprised to see no mention of fish but, anyway, I recommend the authors collaborate with the agroforesters who raise these foods. @elperomyscus.bsky.social

Specifically, modification of habitat can directly impact a species’ viability and should remain a part of the ESA’s definition of harm. We are in a period of unprecedented species extinction and need to safeguard our country’s resources -including biodiversity- for future generations.

Something as simple as: I strongly oppose the proposal to rescind the definition of “harm” as currently stated in the Endangered Species Act (ESA).
