Earth Day reminds us science is stronger when it starts with communities | Op-Ed Science is essential. But the story of how we practice it has expanded over the decades to be more connected to real-world decisions and outcomes.

Science is essential—it helps us understand change and guide decisions. But how we do science is expanding: more collaborative, more connected, more inclusive. When it starts with communities, it leads to solutions that last. My Earth Day op-ed is out www.seattletimes.com/opinion/eart...

I'm an academic author not an editor, but the piece of advice I give others is "have a friend who can give you tough constructive feedback read it"

It is an open symposium, which means anyone can apply to present their research, case study, or tool demo. And we'll use the focus group to generate a multi-coauthor publication.

While it's not necessary, I recommend that interested applicants reach out to me so I can make sure it's a good fit.

Aerial drone image of open coastal water viewed from directly above. On the right side, a fishing vessel has deployed a large purse seine fishing net that extends outward from the stern and occupies a wide area of the surrounding water. Four humpback dolphins are visible near the net, just below the water surface. On the left side of the image, a smaller tourist boat is positioned farther away, oriented roughly parallel to the fishing vessel. While dolphins generally tend to move away from tourist boats, they are more tolerant of them in the presence of fishing gear, with which they interact, likely to forage on the fish caught.

Intensifying fisheries and tourism threaten coastal dolphins. Using drones and machine learning, we show that endangered Indian Ocean humpback dolphins avoid tourist boats, forage near fishing nets, and make trade-offs when both occur.

In a nutshell, the ANES data shows:
