Devastating Transboundary Impacts of Sea Star Wasting Disease on Subtidal Asteroids.
PLoS ONE, 2016 Sea star wasting disease devastated intertidal sea star populations from Mexico to Alaska between 2013-15, but little detail is known about its impacts to subtidal species. We assessed the impacts of sea star wasting disease in the Salish Sea, a Canadian

Sea star populations diverge by positive selection at a sperm‐egg compatibility locus
Ecology and Evolution, 2013 Fertilization proteins of marine broadcast spawning species often show signals of positive selection. Among geographically isolated populations, positive selection within populations can lead to differences between them, and may result in reproductive ...

Multi-star calibration in starphotometry [PDF]
Atmospheric Measurement Techniques, 2023 We explored the improvement in starphotometry accuracy using a multi-star Langley calibration in lieu of the more traditional one-star Langley approach. Our goal was a 0.01 calibration-constant repeatability accuracy, at an operational sea-level facility

Up in Arms: Immune and Nervous System Response to Sea Star Wasting Disease. [PDF]
PLoS ONE, 2015 Echinoderms, positioned taxonomically at the base of deuterostomes, provide an important system for the study of the evolution of the immune system.

Kinematics of sea star legged locomotion
Journal of Experimental Biology, 2021 ABSTRACT Sea stars have slower crawling and faster bouncing gaits. Both speed and oscillation amplitude increase during the transition from crawling to oscillating. In the bouncy gait, oscillating vertical velocities precede oscillating horizontal velocities by 90 deg, as reflected by clockwise circular hodographs.
