Intellectual communities are better and do better when they are welcoming and supportive. That feels like it should be obvious.
But even if diversity and inclusion didn’t make us better scientists (it does) it would make us better humans, and that should be reason enough.

New paper! We use telemetry to identify behaviors of goliath grouper while they form seasonal spawning aggregations. We show how these behaviors change with the lunar cycle, temperatures and current strengths. int-res.com/abstracts/meps/v…

The pink meanie jellyfish was only described in the year 2000 (they even got their own new family!) and we’re totally here for it. The pink meanie hunts the moon jellyfish and helps keep their blooms in check! #coralcitycamera

New polar bear paper. Largely confirmation of what we thought. Evolution & species divergence is less like a tree & more like a vine: lots of intertwining over time until new species can't produce viable offspring. Polar bears & brown bears haven't been separated long enough yet.
