@ucdavis @theNASciences "One might say that natural ecological #systems *don't exist anymore*..."

@ucdavis @theNASciences @eco_hastings "The long-term behavior of the #epidemic is not what you want to focus on. Let's focus instead on dynamics at shorter timescales."
SFI External Prof Alan Hastings @eco_hastings
(@UCDavis), criticizes conventional ecological models, streaming now:
"You're going to want to monitor things that show a large response, and show it relatively quickly."

"We want to use #ComplexSystems methods to show when long transients will arise."

"#Stochasticity produces the very large-amplitude long cycles."
(Left Slide:) "Looking at this species from 1960 to 1970, you'd *think* it existed at a very low density. But then it goes up."
SFI External Prof Alan Hastings (@UCDavis), streaming now:
Different ways to get ecological transients — including "ghost attractors" & "crawl-bys" — and why they aren't always obvious, or why you might have to keep kicking the system to maintain balance.

"The way stochasticity is often modeled is not a good approach for ecological systems."
