Thank you, @bengoldfarb.bsky.social, for your balanced and well-written story on pink salmon in Sitka National Historical Park. It was a pleasure discussing our work with you. www.npca.org/articles/114...

The Pink Wave
A salmon run in an Alaskan park has exploded in recent years. Can a river have too many fish?

Limnologist here It's a bit funny [looking] Freshwater algae are typically phosphorus limited but that switches to nitrogen limitation as P ⬆️ (usually from humans) & the N:P ⬇️ below 16:1 (Redfield ratio). Many cyanobacteria (blue-green algae) can fix their own N & thus bloom in these conditions

Hi, sorry to be a bother, but could fellow #SACNAS members point me to a resource or policy when an abstract review (for a presentation) may have been generated by AI? My friend is in esteemed graduate student in neuroscience but had their abstract flatly rejected, but the review makes no sense.

Quote skeet with a picture of the airplane you'll accept as a bribe
A bizarre-looking mashup of an airplane, submarine, and marine components, the Bartini Beriev VVA 14 has avery strange appearance. The VVA 14 was a Soviet Union response to the fear of a US submarine-driven nuclear assault. This craft was intended to be an amphibious vehicle capable of taking off from land or water. In tight places, its vertical take-off and landing (VTOL) capabilities would prove useful. The Soviets foresaw the VVA 14 gliding low over the ocean surface, conducting high-speed submarine detection missions.

🆕 & #OpenAccess in Frontiers in Ecology and the Environment: Rather than taking a one-way trip to the sea, many young salmonids are making far more complex migrations than previously thought 📄Juvenile salmonids traverse coastal meta-nurseries that connect rivers via the sea doi.org/10.1002/fee....
Juvenile salmonids traverse saltwater environments to inhabit non-natal drainages among Deep Creek, West Twin River, and East Twin River freshwater systems along the Olympic Peninsula, in western Washington State. This schematic highlights empirically observed paths of two juvenile coho (Oncorhynchus kisutch, orange and purple) and one juvenile Oncorhynchus mykiss (yellow) that made complex movements among drainages over periods of 203 days, 305 days, and 241 days, respectively. Numbers track individuals’ chronological detection sequences. Arrows indicate movement paths among drainages, with dashed line arrows showing additional details of individuals that moved back and forth between the East Twin and West Twin Rivers. For presentation purposes, points and arrows are staggered vertically, distances between streams are compressed, and the bottom of the figure points north. Image credit: Su Kim
