In my last post I mentioned that I would look for ways to reduce our exposure to and production of PAHs, and I’ve spent some time searching for specific campaigns, but I haven’t found much that seems like an organized approach. Instead, I found a number of smaller recommendations for individual action. To reduce exposure […]

Go (help a reef) fish!
Over the last few weeks, I’ve described some of the big challenges facing reef fish and the coral reefs they inhabit- some of those issues are very big, such as the scale of climate change and ocean acidification, and some of those issues occur on a much smaller scale, such as when fishermen use cyanide […]
Regenerating a coral reef
In my last post I mentioned some of the challenges facing reefs and reef fish, particularly overexploitation and habitat degradation. Although these issues affect reef fish in different ways, they can work in tandem to intensify conservation problems. The good news is that we have better insight into how to lessen or even remove some […]
Fishing down the coral reef
Over the past week I’ve been looking into the challenges facing reef fishes and the environments they inhabit, and there are some very clear recurrent themes: overexploitation (on a number of levels), habitat degradation (for a variety of reasons), and climate change. These are all big issues and unfortunately some of them are probably not […]
The tropical life aquatic
During a recent trip to New England, I spent an afternoon wandering around an aquarium- I love watching all of the undersea life, but one of my favorite exhibits is always the shallow coral reefs with their diversity of brightly-colored fish. I know that there are a number of conservation concerns for the fish we […]
Getting the water just right
As I have mentioned in previous posts, wetlands around the world are disappearing, in part because of land use changes and climate change. We should all be concerned about these losses because wetlands provide a number of ecosystem services that benefit us all, services like water filtration, vital wildlife habitat, carbon sequestration (in the peat), […]
A disappearing act
I spent the last few days at a conference in New Orleans about the changing Gulf Coast that brought together researchers, engineers, long-time residents, and a wide variety of other people. The point was to share information and viewpoints about what is happening along the coast over the short- and long-term. Sea-level rise and climate […]
Putting otters in the clear
I spent some time this week looking into ways to get involved in otter conservation, and I’ve found a number of activities which run the gamut from pressing a few buttons on your computer to spending some time hanging out in a stream. I’ve divided them up into several categories- hopefully you find something that […]
A shallow, unaltered stream runs through it
In my last post, I mentioned that habitat degradation and human-caused mortality were some of the biggest issues facing river otters. Recent research has tended to support those views, while providing more detail about where, how, and when those issues loom largest. We’ve also seen that otter populations can recover with protection, but there are […]
On a downhill slope
As I started looking into the condition of river otters around the world, it became obvious that a lot of the information out there deals with otters in Europe and North America– I would say easily 90% of what I’ve read so far. In some ways that’s helpful, because it means that researchers have been […]
