A new scorpion genus from California

Graemeloweius_Kovarikia

I was recently lucky to be part of a team, led by Michael Soleglad, that described a new scorpion genus from California, Graemeloweus. The genus includes three species previously placed in genus Pseudoructonus. Interestingly, male reproductive structures (hemispermatophores and mating plugs) suggest that the new genus is more closely related to Kovarkia, a primarily rock-dwelling species in southern California. I look forward to seeing if ongoing genetic work on these genera supports our sister lineage hypothesis.

Invertebrate Biology Course of 2015

I just want to say thank you to my Invertebrate Biology course for a memorable summer session… what a great group! Here they are surveying invertebrates along Connecticut’s rocky intertidal at Avery Point. Invasive jumping spiders were everywhere!

RAD Sequencing of Tarantulas

I just received a grant to conduct RAD (Restriction site Associated DNA) sequencing of Grand Canyon black tarantulas, Aphonopelma marxi, with Dr. Bent Hendrixson! Tissue prep and sequencing will begin this summer using samples collected throughout the Colorado Plateau. For now, enjoy this landscape interpolation of mitochondrial data from A. marxi. Many thanks to Dr. Hendrixson for the inset photo and for collaborating on this project!
