Chromosome Diversification in Antarctic Fish (Notothenioidei)

1998
During recent years cytogenetic studies on Antarctic fish have received increasing attention [1–4]. Representatives from all the families of the Notothenioidei suborder have been studied in High Antarctic, SubAntarctic and cold-PeriAntarctic regions (1).

Cardiovascular control in Antarctic fish

Deep Sea Research Part II: Topical Studies in Oceanography, 2006
Abstract The capacity for synthesis and plasma levels of stress hormones in species with a range of activity patterns suggest that depressed catecholamine synthesis is typical of notothenioid fishes regardless of life style, although they are able to release extensive stores under conditions of extreme trauma.

Atrial Natriuretic Peptides in Antarctic Fish

1998
Atrial natriuretic factors (ANFs) belong to a family of peptides originally described in mammalian heart. Beside ANPs, two other different types of natriuretic peptides with high sequence similarity have been identified, B-type natriuretic peptide (BNP) in the heart of chicken and mammals, and C-type natriuretic peptide (CNP) in the brain [1].

Ocular morphology in antarctic notothenioid fishes

Journal of Morphology, 1988
AbstractBeneath the sea ice at McMurdo Sound, Antarctica, notothenioid fishes are subject to extreme seasonal variation in the annual light cycle including 4 months of continual darkness. Gross and microscopic anatomy of the eyes of 18 species revealed ocular morphology that was generally similar to that of coastal fishes elsewhere in the world, and ...

Helitron transposons in the genome of Antarctic fish

2009
Numerous data indicated that families of mobile elements have gradually accumulated in time to constitute a large fraction of the vertebrate DNA, shaping either genes or the whole genome. Rolling-circle eukaryotic trasposons, known as Helitrons, are widely distributed, from protist to mammal species.

[Helminths of Antarctic fishes].

Wiadomosci parazytologiczne, 2008
Antarctic fishes are represented by sharks, skates (Chondrichthyes) and bony fishes (Teleostei). Teleosts play an important role in the completion of life cycles of many helminth species. They serve as either definitive or intermediate and paratenic hosts. Chondrichthyes are definitive hosts only. Seventy three helminth species occur as the adult stage
