Warm Edge Kelp Populations Show Elevated Volatility to Marine Heatwaves
Ecology Letters, Volume 29, Issue 1, January 2026.Limited data on how heat stress affects species across their distribution restricts prediction accuracy. Our long‐term reef observational data supports a hybrid thermal performance model, whereby thermal limits differ between populations, but performance volatility increases toward species' warm‐edge, heightening vulnerability of warm‐edge populations.

Characterisation of the swimming muscles of two Subantarctic notothenioids [PDF]
, 1999 The histochemical characteristics and distribution of muscle fibre types have been investigated in the swimming muscles of the robalo, Eleginops maclovinus and the lorcho, Patagonotothen tessellata, Subantarctic notothenioids that inhabit the Beagle ...

Aspects of the morphology of phyletically basal bovichtid fishes of the Antarctic suborder Notothenioidei (Perciformes) [PDF]
, 2006 In studying the soft tissue anatomy and histology of notothenioids, especially the bovichtids Bovichtus diacanthus and Cottoperca gobio, I evaluated the structure and phyletic distribution of two characters identified by Balushkin (2000) and a new ocular

Cell Biochemistry and Function, Volume 43, Issue 11, November 2025.ABSTRACT Aquatic ecosystems have their abiotic and biotic factors constantly altered by various factors. Among them, water temperature is an abiotic factor that can significantly affect fish physiology, increasing energy demand, which can impact homeostasis and survival. Endocrine and metabolic changes and enzymatic modulation are referred to as stress

Evolution and Diversification of Antarctic Notothenioid Fishes [PDF]
American Zoologist, 1991 Synopsis. Antarctica supported fossil ichthyofaunas during the Devonian, Jurassic, Cre? taceous and Eocene/Oligocene. These faunas are not ancestral to each other, nor are they related to any component of the modern fauna. About one hundred species of notothenioids dominate a modern fauna of over 200 species of bottom fishes.

Austral vs. Antarctic Notothenioids: Mitochondrial responses to Ocean Acidification [PDF]
, 2012 Antarctic fish species possess very low metabolic rates and poor metabolic plasticity, thus making them extremely vulnerable to changing environmental conditions.

Data from: Physical, chemical, and functional properties of neuronal membranes vary between species of Antarctic notothenioids differing in thermal tolerance [PDF]
, 2019 Disruption of neuronal function is likely to influence limits to thermal tolerance. We hypothesized that with acute warming the structure and function of neuronal membranes in the Antarctic notothenioid fish Chaenocephalus aceratus are more vulnerable to

Life histories and evolution: insights from notothenioids (Teleostei, Perciformes) [PDF]
, 2015 Organisms show an extraordinary variation in their life history traits, both at inter- and intraspecific level, exhibiting phenotypic variations among populations inhabiting different habitat.

Identification of the notothenioid sister lineage illuminates the biogeographic history of an Antarctic adaptive radiation [PDF]
, 2015 Background: Antarctic notothenioids are an impressive adaptive radiation. While they share recent common ancestry with several species-depauperate lineages that exhibit a relictual distribution in areas peripheral to the Southern Ocean, an understanding ...

Diversity and Distributions, Volume 31, Issue 7, July 2025.ABSTRACT Aim Recent climate‐driven changes in the Antarctic marine environment, marked by regional differences between West and East Antarctica, may alter ecosystem dynamics. As key components of the food web, fish might reflect these changes. This study examines fish biodiversity patterns across four typical Antarctic seas by integrating eDNA analysis
