Super happy to have @ulaskimarta.bsky.social joining us at @uwsafs.bsky.social! Looking forward to working together!
Mismatches between invasive species policy, which relies on administrative borders, and scientific research conducted at ecological units complicate regulation, risk assessment, and biosecurity. Here we explore some solutions.

River need greater protection, but to date our methods for tracking protection status have been limited. In this post I describe a new method from @oldenfish.bsky.social @americanrivers.bsky.social and Conservation Science Partners - the Protected River Index

So glad that you investigated this issue! PISS is crappy, and it needs to be called out.
π£οΈ MAJOR ANNOUNCEMENT: Over 80% of our nationβs 4.4M miles of rivers arenβt adequately protected!
Our brand new peer-reviewed research with Conservation Science Partners published in Nature Sustainability shows just how vulnerable our rivers are.
β‘οΈ Learn more: www.americanrivers.org/npra-explore...
Expanding river-specific protections, such as new federal and state Wild and Scenic Rivers and Outstanding Resource Waters, would ensure effective, durable protection measures tailored to rivers.
Individual states can promote river protection through new or strengthened riparian buffer legislation, administrative rules, or agricultural/forestry best practices. Protecting rivers flowing through private lands, such as those offered by easements or land trust acquisitions/agreements, is key.
Federal public lands have an outsized role in protecting rivers nationwide, and multiple-use lands provide a major opportunity to scale protections; weakening or eliminating existing environmental policy mechanisms would undermine these safeguards.
Protection often does not coincide with other conservation objectives, where only a small fraction of watersheds with high biodiversity, habitat intactness and importance to drinking water supply are adequately protected.
Protection is overwhelmingly driven by land-based mechanisms, which are often spatially misaligned with hotspots of freshwater biodiversity and may inadequately safeguard rivers from upstream threats. Protection is also uneven across river types (intermittent rivers less protected) and geographies.
Americaβs rivers are alarmingly under protected. Just over one-tenth (12%) of rivers in the contiguous United States and less than one-fifth (19%) nationwide are currently protected at a level deemed viable, while two-thirds remain entirely unprotected under the mechanisms assessed in this study.

A huge congrats Tim!
I enjoyed your talk Miguel. It was early for me (6:30 am), but it was well worth it!
Nah ... I end up buying caps on eBay. I mostly use uncrimped caps (i.e., before they are used).
Late night, but there is no better feeling that having stable isotope samples all prepped! βοΈπ
Finally found some time to reconnect with my caps. Red swamp crayfish in all its glory. Adding it to my office wall! @newbelgium.bsky.social @pikebrewing.bsky.social
