Comparative and evolutionary genomics of secondarily temperate adaptation in a non-Antarctic icefish
Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2024-12-01

Comparative antifreeze trait analyses of Antarctic and temperate sister species pairs shed light on tempo of adaptive trait loss under relaxed selection
… notothenioid species pair, the S. American icefish Champsocephalus esox and its Antarctic sister C. gunnari. C. esox co-occurs geographically with H. bispinis, and while AFGP coding sequences also persist in its genome, they are not transcribed or expressed into protein. We constructed a …

Effects of Hyperoxia on Thermal Tolerance and Indicators of Hypoxic Stress in Antarctic Fishes That Differ in Expression of Oxygen-Binding Proteins
Antarctic icefishes (Family Channichthyidae) are unique in lacking the oxygen carrier hemoglobin (Hb) in their blood, leaving them with only 10% of the oxygen-carrying capacity observed in closely related red-blooded fishes. Previous studies have shown that icefishes have lower critical thermal …

The influence of environmental temperature on the thermal tolerance of Antarctic notothenioid fishes
… in 11 of the 14 species of the Antarctic icefishes (family Channichthyidae). While the icefishes are a small monophyletic group within the suborder Notothenioidei, they mirror the larger group’s divisions in geographic distribution and lifestyle making this family a useful system for …

Differential gene expression analysis reveals functional roles of cryptic orange-pigmented organ in the colorless head kidney of Antarctic icefishes
… head kidney of the hemoglobinless Antarctic icefishes. No macroscopically visible discrete organ has previously been reported in Antarctic fishes or teleost fishes in general. To assess the tissue type and functions of this cryptic orange body, we performed RNA sequencing and analyzed the …
