Habitable sphere and fine structure constant [PDF]
arXiv, 2005 Future space missions, TPF and Darwin will focus on searches of signatures of life on extrasolar planets. In this paper we look for model independ definition of the habitable zone. It will be shown that the radius of the habitable sphere depends only on the constants of the Nature. Key words: Habitable sphere, fine structure constant.

A Habitable Planet around HD 85512? [PDF]
arXiv, 2011 Aims: In this study we assess the habitability of HD85512b, a 3.6M_Earth planet orbiting a K5V star. The radial velocity data and orbital parameters for HD 85512 b have just been published, based on data from the dedicated HARPS-upgrade GTO program. Methods: This paper outlines a simple approach to evaluate habitability of rocky planets from radial ...

Habitability in the Solar System and New Planetary Missions [PDF]
arXiv, 2013 Definition of habitability depends on the organisms under consideration. One way to determine habitability of some environment is to compare its certain parameters to environments where extremophilic micro-organisms thrive on Earth. We can also define more common habitability criteria from the life as we know it.

The Lost Large Mammals of Arabia
Journal of Biogeography, EarlyView.ABSTRACT Aim If successful, plans to restore the vegetation of the Arabian Peninsula (AP) as announced by the Middle East and Saudi Green Initiatives will see the greatest increase in vegetation cover since the beginning of the Holocene Humid Phase (HHP), roughly 9–10,000 years ago.

Revisiting Ancient Forests: Insights From the Mid‐Pliocene to Predict Future Climate Impacts
Journal of Biogeography, EarlyView.ABSTRACT Aim The potential analogues in Earth's past may hold insight on how modern European forests will react to different levels of future warming. There is a lack of comparison between future warming and its most recent climate analogue 3.25 million years ago during the mid‐Piacenzian warm period.
