More than 3,000 animal species in the world today are considered endangered, with hundreds more categorized as vulnerable. Currently, ecologists don t have reliable tools to predict when a species may become at risk.
A new paper published in
Nature Ecology and Evolution, Management implications of long transients in ecological systems, focuses on the transient nature of species and ecosystem stability and illustrates how management practices can be adjusted to better prepare for possible system flips. Some helpful modeling approaches are also offered, including one tool that may help identify potentially endangered populations.

Allison Needles: What is a Community Land Trust? And could one help with Tacoma s homelessness crisis?
News Tribune, Tacoma, Wash. 12/18/2020 Allison Needles, The News Tribune (Tacoma, Wash.)
Dec. 18 When Tacoma Housing Now took over vacant Gault Middle School in November to shelter unhoused people, the action came with a list of demands.
The most prominent of them insisted on making Gault, which has sat vacant for a decade, part of a Community Land Trust, also called a CLT.
That same demand fueled the housing advocacy group to block traffic and pitch a tent in the middle of the intersection on Pacific Avenue and 15th Street on Dec. 8.
Stormwater flushes bits of aging vehicle tires on roads into neighboring waterways
Researchers have discovered a chemical that kills coho salmon in urban streams.
December 8, 2020
Every fall, more than half the coho salmon that return to Puget Sound s urban streams die before they can spawn. In some streams, all die. But scientists didn t know why.
Now, a U.S. National Science Foundation-funded research team at the University of Washington Tacoma and Washington State University Puyallup has discovered the answer. When it rains, stormwater flushes bits of aging vehicle tires on roads into neighboring streams. The killer is in the mix of chemicals that leaches from tire wear particles: a molecule related to a preservative that keeps tires from breaking down too quickly.
