Top Spur Trail overlooking Mount Hood with Jenn and Jamie back in 2012.
Digging into some old, unpublished photographs, I came across a trip to Portland, Oregon, for the annual meeting of the Ecological Society of America in 2012. Jamie kindly hosted Jenn and me in her home (then did so again in 2017), and we took a trip to Top Spur Trail after the meeting’s end. Here are some landscape and panorama images from Top Spur Trail approaching Mount Hood.
Located in Monterey Square (not Pulaski Square, which is a little southwest) commemorates Casimir Pulaski, a Polish immigrant who lead, fought, and died in the American Revolutionary War. It also likely contains the remains of Pulaski, which, according to the infallible Wikipedia, suggest that he may have been intersex.
Nicole ran, and achieved a PR, in a half-marathon yesterday, while Amos and I drank coffee and watched.
Murph is a yellow-bellied slider (Trachemys
Barzini and Monstrego are two other pet turtles of the same species but a different sub-species: Trachemys scripta elegans. Both escaped in the Summer of 2015, but I recovered Barzini about a year and a half later.
Here, Nicole and I pose for Murph’s release.
One of my favorite streams within the Las Cruces preserve is Quebrada Cerro, which drains nearly exclusively primary forest. The water is clear and filled with tadpoles and belostomatids, but surprisingly few crabs, to Kainalu’s disappointment.
This summer, I found a tile hot glued to a PVC pipe within the stream—a remnant of a 2015 primary productivity study one of Frank Camacho’s students was performing that was washed out in most sites.
To some degree, I have been working with crabs at Las Cruces since 2013, and I have identified only a handful of males using various keys (the latest by Magalhaus et al 2015). This year, I aimed to identify all the crabs we caught and studied if we could, so Gabby, Juliet and I sat down to identify two males, randomly chosen from a set we had discovered trematode metacercariae in, using the key.
As we slowly moved through the key towards Allacanthos pittieri which I had previously identifed in other summers and a few days earlier as a brush up, Gabby expressed some skepticism and challenged my guidance through the key. I dismissed her concerns to some degree (and I hope she’ll forgive me) as we worked through defining the terms in the first couplet, but eventually had a look at her crab’s gonapods (the structures used to transfer sperm in decapods and commonly used to identify them to species). I immediately and excitedly knew she had something else.
The three of us spent the rest of the day keying the new crab and confirming the identity of the other, and it was glorious. There is nothing cooler than working with engaged, enthusiastic, and smart students… especially on something as cool as a second crab species!
While I think we stumbled on a couplet (11) and eventually mis-identified the crab as Ptychophallus montanus, I think we’re confident that the other species of crab is P. paraxanthusi. At this point, we’re working on markers of the crab that don’t involve microscopy and allow us to identify the females.
