Hahaha - we were thinking it might be an embargoed story broken by this outlet⦠seems like a made up story would be less conservative in the details, but yea gotta be fake if nothing else comes out in the next few days

Very excited to share this new exploration of motifs and their impacts on the dynamics of the entire network in PNAS! I learned a lot working with this crew (as usual)... with @mhab.bsky.social @akfbio.bsky.social and @thilogross.bsky.social !
New paper with @mhab.bsky.social @jdyeakel.bsky.social and @thilogross.bsky.social out now in @pnas.org! We show when and why you can know something about an entire network, just by knowing the behavior of it's building blocks: doi.org/10.1073/pnas...

Mark Novak, @kecoblentz.bsky.social, John DeLong FTW - a very cool paper I need to dig carefully through!
Novak et al. derive a functional response model that unifies Hollingβs classical forms. The model clarifies when linearity can be a mechanistically-reasoned description of predator feeding rates and the impact it has on predator-prey dynamics.
