Keystone predators govern the pathway and pace of climate impacts in a subarctic marine ecosystem
Predator loss and climate change are hallmarks of the Anthropocene yet their interactive effects are largely unknown. Here, we show that massive calcareous reefs, built slowly by the alga Clathromorphum nereostratum over centuries to millennia, are now declining because of the emerging interplay between these two processes. Such reefs, the structural base of Aleutian kelp forests, are rapidly eroding because of overgrazing by herbivores. Historical reconstructions and experiments reveal that overgrazing was initiated by the loss of sea otters, Enhydra lutris (which gave rise to herbivores capable of causing bioerosion), an...

Cascading social-ecological costs and benefits triggered by a recovering keystone predator
Predator recovery often leads to ecosystem change that can trigger conflicts with more recently established human activities. In the eastern North Pacific, recovering sea otters are transforming coastal systems by reducing populations of benthic invertebrates and releasing kelp forests from grazing pressure. These changes threaten established shellfish fisheries and modify a variety of other ecosystem services. The diverse social and economic consequences of this trophic cascade are unknown, particularly across large regions. We developed and applied a trophic model to predict these impacts on four ecosystem services. Resu...

Hyperthyroidism: Too Much Of A Good Thing
By: Dr. Alan Christianson When someone you know is living with hypothyroidism, it can be tempting to think that if only the doctor would prescribe an extra helping of thyroid hormone, your friend or loved one would feel so much better and would enjoy life more. And in some cases, an extra helping might be in order. In other cases, not so much. Too much thyroid hormone can actually be dangerous, which is why doctors are loathe to bump the levothyroxin dosage up an extra 25 micrograms or so for one of their patients who's still experiencing hypothyroid symptoms. Tests always come first, and there's a good reason for that....
