Top predator feeding ecology and microplastic (MP) contamination on the far eastern South American coast: Evidence of MP trophic biotransfer
Read more of: Top predator feeding ecology and microplastic (MP) contamination on the far eastern South American coast: Evidence of MP trophic biotransferThis study describes the feeding ecology, spatial distribution of each ontogenetic phase and the corresponding plastic debris contamination, in the Caribbean sharpnose shark, Rhizoprionodon porosus as a function of spatial-temporal […]

A Comparison of Auroral Oval Proxies With the Boundaries of the Auroral Electrojets
Read more of: A Comparison of Auroral Oval Proxies With the Boundaries of the Auroral ElectrojetsThe boundaries of the auroral oval and auroral electrojets are an important source of information for understanding the coupling between the solar wind and the near-earth plasma environment. Of these […]

An iridovirus from the Antarctic seaspider Pentanymphon antarcticum (Pycnogonida)
Read more of: An iridovirus from the Antarctic seaspider Pentanymphon antarcticum (Pycnogonida)The Antarctic seaspider Pentanymphon antarcticum is a benthic species in the Southern Ocean, but little is known about its pathogen profile. In this study, we provide a draft genome for […]

Long‐Term Variability and Tendencies in Mesosphere and Lower Thermosphere Winds From Meteor Radar Observations Over Esrange (67.9°N, 21.1°E)
Read more of: Long‐Term Variability and Tendencies in Mesosphere and Lower Thermosphere Winds From Meteor Radar Observations Over Esrange (67.9°N, 21.1°E)Long-term variabilities of monthly zonal (U) and meridional winds (V) in northern polar mesosphere and lower thermosphere (MLT, ∼80–100 km) are investigated using meteor radar observations during 1999–2022 over Esrange […]

On the Wave-Normal Distribution of Lightning-Generated Whistlers and Their Propagation Modes
Read more of: On the Wave-Normal Distribution of Lightning-Generated Whistlers and Their Propagation ModesObservations from Van Allen Probes are analyzed to obtain the statistical wave normal distribution of lightning-generated whistlers (LGWs). An automatic algorithm is developed to identify burst mode waveform data with […]

Estimated summer abundance and krill consumption of fin whales throughout the Scotia Sea during the 2018/2019 summer season
Read more of: Estimated summer abundance and krill consumption of fin whales throughout the Scotia Sea during the 2018/2019 summer seasonAmong large cetaceans in the Southern Hemisphere, fin whales were the most heavily exploited in terms of numbers taken during the period of intense industrial whaling. Recent studies suggest that, […]

Introduced species infiltrate early stages of succession after glacial retreat on sub-Antarctic South Georgia
Read more of: Introduced species infiltrate early stages of succession after glacial retreat on sub-Antarctic South GeorgiaBiological invasions are one of the main drivers of global biodiversity decline. At the same time, glacial retreat induced by climate warming is occurring at an alarming rate across the […]

Location Dictates Snow Aerodynamic Roughness
Read more of: Location Dictates Snow Aerodynamic RoughnessWe conducted an experiment comparing wind speeds and aerodynamic roughness length (z0) values over three snow surface conditions, including a flat smooth surface, a wavy smooth surface, and a wavy […]

Testing the resilience, physiological plasticity and mechanisms underlying upper temperature limits of Antarctic marine ecto-therms
Read more of: Testing the resilience, physiological plasticity and mechanisms underlying upper temperature limits of Antarctic marine ecto-thermsAntarctic marine ectotherms live in the constant cold and are characterised by limited resilience to elevated temperature. Here we tested three of the central paradigms underlying this resilience. Firstly, we […]

Lessons learned from shallow subglacial bedrock drilling campaigns in Antarctica
Read more of: Lessons learned from shallow subglacial bedrock drilling campaigns in AntarcticaWe review successes and challenges from five recent subglacial bedrock drilling campaigns intended to find evidence for Antarctic Ice Sheet retreat during warm periods in the geologic past. Insights into […]

The demise of large tropical brachiopods and the Mesozoic Marine Revolution
Read more of: The demise of large tropical brachiopods and the Mesozoic Marine RevolutionChanges in predator–prey interactions are often implicated as drivers of major evolutionary change. A prominent example is the dramatic changes in shallow marine assemblages during the Mesozoic Marine Revolution (MMR) […]
