Background and Aims … Coping with both UV-B radiation and desiccation was essential for early land plants. In bryophytes, UV-B screening and desiccation tolerance partially depend on the physicochemical features of cell walls, which may also constrain photosynthesis.
The Galactic cosmic ray spectrum manifests pronounced variations over the 11-year sunspot cycle and more subtle variations over the 22-year solar magnetic cycle.
The Galactic cosmic ray spectrum manifests pronounced variations over the 11-year sunspot cycle and more subtle variations over the 22-year solar magnetic cycle.
The Galactic cosmic-ray spectrum manifests pronounced variations over the 11 yr sunspot cycle and more subtle variations over the 22 yr solar magnetic cycle. An important tool to study these variations is repeated latitude surveys with neutron monitors (NMs)…
Fast ice is an important component of Antarctic coastal marine ecosystems, providing a prolific habitat for ice algal communities. This work examines the relationships between normalized difference indices (NDI)…
Adult specimens, additional juvenile specimens, egg cases and embryos were used to provide a more detailed anatomical description of the Kerguelen sandpaper skate Bathyraja irrasa…
Echosounder data are widely collected and employed to address multitude scientific questions, from characterizing pelagic marine ecosystems, to investigating the behaviour and dynamics of marine organisms, and estimating the abundance and biomass of marine resources.
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.

During the last deglaciation (21,000 to 7,000 years ago) global sea level rise was punctuated by several abruptmeltwater spikes triggered by the retreat of ice sheets and glaciers world-wide. However, questions regarding therelative timing…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to … be exceptional for astronomy. The seeing (above ¡30m height), coherence time…
PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/ … infrared telescope to be located at Dome C on the Antarctic plateau. The atmospheric conditions at Dome C … deliver a high sensitivity, high photometric precision, wide-field, high spatial resolution…
In this investigation different sorbent materials (MYCELX coated sand, granular activated carbon (GAC) and surfactantmodifed … zeolite (SMZ)) were tested for their suitability for capture of sparingly soluble hydrocarbons in soil water.
