When it comes to interactions between crabs, whether of the same species or of differing species, size matters. When crabs run into each other out on tide flats, in lagoons, or channels, they might compete for food or shelter, or they may actually try to prey on each other. In these encounters, the general rule of #CrabLife is that bigger crabs win over smaller crabs. So knowing the size of not only green ...

We are Crab Team after all, so it’s perhaps no surprise that we are not shy about getting up to our elbows in details about the crabs we catch. But what can we actually learn from looking at size data of crabs? What makes handling all the angry pinchers worthwhile?
We’re covering this rich topic in two issues of Protocol in Focus. This time, we’ll shed light on what we can ...

Crab Team has come a long way since a handful of intrepid early-adopter volunteers put their boots in the mud for our pilot season in August 2015. Since that time, the network has:

This year marks Crab Team’s eighth monitoring season, a fact that completely blows our minds. Some of the Crab Team sites have been systematically sampled since we kicked off in August 2015. As this long term ecological dataset grows even longer, it becomes increasingly valuable to look at changes over space and time.

One strength of the Crab Team protocol is that it enables us to confidently compare findings among sites, and track changes over time – even if different people are doing the sampling. With sampling on this scale, even the small steps can be important to what we learn from the data. Protocol in Focus allows us to expand on these details, and offer an opportunity to see all the behind-the-scenes planning that goes into methodology.

In addition to creating a scientifically robust sampling scheme, and one that is sensitive to finding green crab when they are rare, Crab Team also put a great deal of thought and guidance into the protocol with the goal of being good stewards of Washington’s shorelines. Even though our goal is to detect green crab as they first arrive and help avoid ecological damage, it is certainly true that the act of sampling itself can be a disturbance to a site. ...

HEOR or HENU? Crab Team volunteers know it’s one of the most challenging questions we face during sampling. Telling hairy shore crabs (HEOR) apart from purple shore crabs (HENU) can be very tricky, especially when all you have is two tiny molted carapaces. It’s not only shore crabs; several groups of crabs can be tricky to distinguish from each other, even if you know what you are looking for.
As you learn a new set of species, whether it’s birds, ...

The recent captures of invasive European green crabs, the first documented in Washington’s Salish Sea, have garnered a lot of recent media attention. We are thrilled that local residents are eager to help protect shorelines from this global invasive species and have set about looking for European green crabs as they walk the beach, paddle the waters, and pull up crab pots. Given 2,500 miles or so of shoreline, this network of “Eyes on the Beach” is critical to ...
