Our new paper in @RSocPublishing Proceedings B shows that denser, and more sheltered, #kelpforests can withstand serious stressors amid warming ocean temperatures. We also explored the response of 149 taxa to recent kelp declines and found... (1/6) https://t.co/o1KXTJUdZw

Ecological communities can be stable over multiple generations, or rapidly shift into structurally and functionally different configurations. In kelp forest ecosystems, overgrazing by sea urchins can...

👉Conservation performance significantly increased with increasing MPA age and habitat diversity. (4/5)

👉Targeted fish species biomass was significantly higher in 22 out of 59 MPAs (37%), although 46 (78%) had elevated biomass in MPAs. (3/5)

👉At the scale of California's MPA network, targeted (i.e., fished) fish biomass was significantly greater inside no-take MPAs compared with areas that allowed take. . 👉Three out of 4 regions exhibited significantly higher targeted fish biomass inside no-take MPAs. (2/5)

Our study published yesterday in @ConBiology shows that the conservation performance of marine protected areas (MPAs) accrues across ecosystems in individual MPAs and in a large #MPA network. We synthesized decades of monitoring data and found... (1/5)

Excited that our recent #openaccess paper in @ConBiology on ecological #stability and #MPAs is copy and type-set! It's been a blast presenting on this contribution over the past few months. Thanks all for the great questions and interest!
In this #openaccess article, Srednick and Swearer share their findings on the effects of protection and temperature variation on temporal stability in a #marine reserve network.🌊 Learn more at https://t.co/IN3H9O1waj

👉This study increases our understanding of (1) the community-wide consequences of kelp loss, (2) where kelp forests are likely to withstand multiple #climate stressors on their own, and can (3) help inform siting for #kelp #restoration (5/6)

👉Persistent kelp forests (those where kelp density did not significantly decline) also had higher densities of kelp to begin with, were relatively shallow, had a gradual reef slope, and were protected from wave exposure (4/6)

👉Patches of dense kelp can prevent shifts in sea urchin foraging behavior, and these persistent forests are better at withstanding multiple stressors (3/6)

👉Taxonomic community structure dramatically shifted during 2014-2016 marine heatwave and did not return. While the number of taxa did not decline, changes in their relative abundances led to an overall decline in taxonomic diversity for marine algae and invertebrates (2/6)

Our new @ucsb_nceas #California MPA working group paper out in @PaN_BES led by @ChrisFree14 Do MPAs meet their human use objectives? We found that human engagement is promoted by developing land-based amenities that increase access to coastal MPAs ⤵️ https://t.co/40LB8d8Euq

Our new paper in @NatureComms uses a multi-species, multi-heatwave framework to model MHW impacts on marine predators. We find a surprising diversity of impacts across species and MHWs, signaling a need for ecosystem-based investigations of MHW impacts. https://t.co/sNrLhxMVyR

Nice coverage by @ethanpfreedman in @hakaimagazine on our recent paper: The 2014–2016 marine heatwave transformed the ecosystem of the northeast Pacific. Some of those changes seem here to stay. https://t.co/Hul1Ppn8CC via @hakaimagazine
