Characterization of complete mitochondrial genome and gene organization of sharp-spined notothenia, Trematomus pennellii (Perciformes: Nototheniidae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
The complete mitochondrial genome of Trematomus pennellii was determined by MiSeq platform. The mitogenome of T. pennellii was 15,976 bp in length and encoded 37 genes (13 proteins, 22 tRNAs, 2 ribosomal RNAs) and a non-coding control region (D-Loop ...

Population genomics of an icefish reveals mechanisms of glacier-driven adaptive radiation in Antarctic notothenioids

open access: yesBMC Biology, 2022
Background Antarctica harbors the bulk of the species diversity of the dominant teleost fish suborder—Notothenioidei. However, the forces that shape their evolution are still under debate.

Feeding habits in two sympatric species of Notothenioidei, Patagonotothen cornucola and Harpagifer bispinis, in the Chilean Patagonian channels and fjords

open access: yesPolar Biology, 2016
Diet compositions of Patagonotothen cornucola and Harpagifer bispinis were studied from two localities, one with continental influence in a wind-protected area (Puerto Riquelme) and another with oceanic influence in a wind-exposed area (Puerto Williams).
