Global distribution of aquatic animal telemetry effort reveals geographic biases and opportunities for more inclusive tracking studies

open access: yesConservation Science and Practice, EarlyView.
Despite broad global distribution of aquatic telemetry studies, important biogeographic regions remain poorly investigated. The most important variables correlated with the distribution of telemetry studies were political stability, conservation funding, number of scientific documents, and English as a first language.

Analysis of the antifreeze glycoprotein containing genomic locus in the Antarctic notothenioid fish dissostichus mawsoni [PDF]

open access: yes, 2010
Development of the Antarctic Circumpolar Current (ACC) circa 25 mya resulted in cooling of the high latitude waters of the Southern Ocean to a chilly -1.86 °C (near the freezing point of seawater) and extinction of most of the late Eocene temperate fish ...

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Acoustic and ecological investigations into predator-prey interactions between Antarctic krill (Euphausia superba) and seal and bird predators [PDF]

open access: yes, 2008
1. Antarctic krill (Euphausia superba) form aggregations known as swarms that vary greatly in size and density. Six acoustic surveys were conducted as part of multidisciplinary studies at two study sites, the western and eastern core boxes (WCB and ECB),

Genetic homogeneity and circum-Antarctic distribution of two benthic shrimp species in the Southern Ocean, Chorismus antarcticus and Nematocarcinus lanceopes [PDF]

open access: yes, 2010
During the last years, molecular studies revealed significant population differentiation and cryptic species within various benthic and pelagic marine Antarctic taxa.

Geolocation reveals wintering sites of near‐extinct Caucasian breeding sea duck

open access: yesIbis, EarlyView.
We obtained 14 sets of full annual cycle geolocator tracks from 13 individual nesting female Velvet Scoter Melanitta fusca from the relict Caucasian population at their last remaining breeding site, Lake Tabatskuri, Georgia. Results showed that females wintered at widespread discrete localities in Ukraine, around the coasts of the Crimean Peninsula and

Effects of non-fish based raw materials on the fish muscle quality of salmonids [PDF]

open access: yes, 2013
Salmonids are considered as fatty fish and a healthy food. They are characterized by a high proportion of n-3 long chain polyunsaturated fatty acids (n-3 LCPUFA).

Benzo(a)pyrene Metabolism and EROD and GST Biotransformation Activity in the Liver of Red- and White-Blooded Antarctic Fish. [PDF]

open access: yes, 2015
Climate change and anthropogenic pollution are of increasing concern in remote areas such as Antarctica. The evolutionary adaptation of Antarctic notothenioid fish to the cold and stable Southern Ocean led to a low plasticity of their physiological ...

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

open access: yesJournal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Invertebrate muscle performance at high latitude: swimming activity in the Antarctic scallop, Adamussium colbecki [PDF]

open access: yes, 2005
The escape swimming performance of the Antarctic scallop, Adamussium colbecki, was measured in animals acclimated for 6 weeks to –1, 0 or 2°C and tested at –1.5 to +1.5°C. Clap duration and swimming velocity were significantly related to temperature, but
