Gray whales are washing up dead on the West Coast. The reason is alarming
Up and down the Pacific coast, dead gray whales are mysteriously washing ashore—and scientists think they know why

Amazing work showcasing the value of long-term monitoring data: Gerraty et al. document declines in the sea-palm #kelp #Postelsia associated w/ the 2014-16 northeast Pacific heatwave & failure to recover due to expansion of mussel beds during the seastar-wasting epidemic. 🤯🌊🦑 doi.org/10.1002/eap....
Sea palms - *Postelsia palmaeformis* - growing on a Northern California rocky reef. These stubby, amazing kelps grow in some of the most wave-exposed intertidal habitats, capitalizing on disturbances in the mussel beds to grow. They really do look like little palm trees, with long, shaggy blades growing from the tops of their hollow stipes. Somewhat astonishingly - though it makes sense once you consider their hollow stipes - their closest relative is the huge, canopy-forming bull kelp, *Nereocystis luetkeana*.

It's never occurred to me that it IS an assumption. This is the most astonishing start to a paper I've read in years: "Living organisms are assumed to produce same-species offspring. Here, we report a shift from this norm in Messor ibericus, an ant that lays individuals from two distinct species."

One mother for two species via obligate cross-species cloning in ants - Nature
In a case of obligate cross-species cloning, female ants of Messor ibericus need to clone males of Messor structor to obtain sperm for producing the worker caste, resulting in males from the same mother having distinct genomes and morphologies.
