The Martian and extraterrestrial uv radiation environment. Part II: Further considerations on materials and design criteria for artificial ecosystems
Read more of: The Martian and extraterrestrial uv radiation environment. Part II: Further considerations on materials and design criteria for artificial ecosystemsUltraviolet radiation is an important natural physical influence on organism function and ecosystem interactions. The UVradiation fluxes in extraterrestrial environments are substantially different from those experienced on Earth. On Mars, […]

Reducing uncertainty on the Grand Bank: tracking and vessel surveys indicate mortality risks for common murres in the North-West Atlantic
Read more of: Reducing uncertainty on the Grand Bank: tracking and vessel surveys indicate mortality risks for common murres in the North-West AtlanticSeabirds and other marine animals are at risk from anthropogenic activities that target them directly and those that can harm them incidentally. We integrate year-round tracking and vessel studies to […]

Martian polar expeditions: problems and solutions
Read more of: Martian polar expeditions: problems and solutionsThe Martianpolar ice caps are regions of substantial scientific interest, being the most dynamic regions of Mars. They are volatile sinks and thus closely linked to Martian climatic conditions. Because […]

‘Astrobiology’ and the ethics of new science
Read more of: ‘Astrobiology’ and the ethics of new scienceAstrobiology has recently been feted as a science for the twenty-first century. Founded as a science in the Soviet Union in 1953, its recent manifestation has been accompanied by a […]

Total solar eclipse effects on VLF signals: observations and modeling
Read more of: Total solar eclipse effects on VLF signals: observations and modelingDuring the total solar eclipse observed in Europe on August 11, 1999, measurements were made of the amplitude and phase of four VLF transmitters in the frequency range 16–24 kHz. […]

On the comparison of population-level estimates of haplotype and nucleotide diversity: a case study using the gene cox1 in animals
Read more of: On the comparison of population-level estimates of haplotype and nucleotide diversity: a case study using the gene cox1 in animalsEstimates of genetic diversity represent a valuable resource for biodiversity assessments and are increasingly used to guide conservation and management programs. The most commonly reported estimates of DNA sequence diversity […]

Short- and long-term consistency in the foraging niche of wandering albatrosses
Read more of: Short- and long-term consistency in the foraging niche of wandering albatrossesThe wandering albatross (Diomedea exulans) is regarded as a generalist predator, but can it be consistent in its foraging niche at an individual level? This study tested short- and long-term […]

Investigating the possible association between thunderclouds and plasmaspheric ducts
Read more of: Investigating the possible association between thunderclouds and plasmaspheric ductsIt has been suggested that quasi-electrostatic electric fields from thunderclouds might produce whistler ducts by driving plasma interchange of geomagnetic flux tubes. Using lightning activity as a proxy for the […]

Benthic organisms and environmental variability in Antarctica: responses to seasonal, decadal and long-term change
Read more of: Benthic organisms and environmental variability in Antarctica: responses to seasonal, decadal and long-term changeMarine organisms in Antarctica live in an environment which exhibits variability in physical processes over a wide range of temporal scales, from seconds to millennia. This time scale tends to […]
