    Fjord oceanographic dynamics provide refuge for critically endangered #Pycnopodia helianthoides: Alyssa-Lois Madden Gehman et al. royalsocietypublishing.org/doi

    "in the summer, there is a lot of glacial runoff, dumping a lot of really cold water into the #fjords. Then, because the #SeaStars do not like cold water, they go deeper. And that may be shielding them from #SeaStarWastingDisease"

    Raising Hungry #SeaStar Babies Is No Cinch baynature.org/article/raising-

    "Not so long ago, you could count on #pycnopodia to devour #PurpleUrchins and keep them from eating too much #kelp. A decade ago, the mysterious wasting disease began plaguing #SeaStars, right around the time that a #MarineHeatWave struck... In the absence of their primary predator, urchin populations exploded. Since then they have mown across the sea floor unhindered, leaving urchin barrens where #KelpForests once flourished."
