Multi-star calibration in starphotometry [PDF]

open access: yesAtmospheric 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]

open access: yesPLoS ONE, 2015
Echinoderms, positioned taxonomically at the base of deuterostomes, provide an important system for the study of the evolution of the immune system.

Microbial dysbiosis precedes signs of sea star wasting disease in wild populations of Pycnopodia helianthoides

open access: yesFrontiers in Marine Science, 2023
Sea star wasting (SSW) disease, a massive and ongoing epidemic with unknown cause(s), has led to the rapid death and decimation of sea star populations with cascading ecological consequences.

Biology of Incidental Catch Sea Star Stellaster childreni Gray, 1840 (Echinodermata: Asteroidea), from Malaysian Borneo Exclusive Economic Zone

open access: yesThe Scientific World Journal, 2017
Sea star (class Asteroidea, phylum Echinodermata) is one of the most successful marine organisms inhabiting a wide range of habitats. As one of the key stone species, sea stars are responsible for maintaining much of the local diversity of species within

A New Record of Sea Star Genus Nearchaster (Asteroidea: Notomyotida: Benthopectinidae) from East Sea, Korea

open access: yesAnimal Systematics, Evolution and Diversity, 2015
An asteroid specimen was collected in adjacent water of Gisamun, Gangwon-do in the East Sea, Korea at a depth of 170 m by fishing net at May 2013.

Complete mitochondrial genome of a sea star, Linckia laevigata (Echinodermata, Asteroidea, Valvatida, Ophidiasteridae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
We determined the complete mitochondrial genome sequences of an asteroid Linckia laevigata belonging to the order Valvatida. The complete mitogenome of L. laevigata was 16,371 bp in length and consisted of 13 protein-coding genes (PCGs), two rRNA, and 22

The Microbial Landscape of Sea Stars and the Anatomical and Interspecies Variability of Their Microbiome

open access: yesFrontiers in Microbiology, 2018
Sea stars are among the most important predators in benthic ecosystems worldwide which is partly attributed to their unique gastrointestinal features and feeding behaviors.
