Habitability has been generally defined as the capability of an environment to support life. Ecologists have been using Habitat Suitability Models (HSMs) for more than four decades to study the habitability of Earth from local to global scales. Astrobiologists have been proposing different habitability models for some time, with little integration and consistency between them and different in function to those used by ecologists. In this white paper, we suggest a mass-energy habitability model…

The Astrobiological Significance of Caves on Earth and on Mars
Caves are geologic entities that can be frequently found around the globe. Cave-like features have been documented on Mars by satellite imagery and special detection devices. On Earth Subterranean

The appellation ‘habitable zone’ in astrobiology in sooth evinces an overlooked and winding history that can be traced back to the 19th century. This paper sketches how this term from geography was

Habitability as a Tool in Astrobiological Exploration
Habitability: A Review.
TLDR
This review on habitability defines it as the ability of an environment to support the activity of at least one known organism and adopts a binary definition of "habitability" and a "habitable environment".
From climate models to planetary habitability: temperature constraints for complex life
Abstract In an effort to derive temperature-based criteria of habitability for multicellular life, we investigated the thermal limits of terrestrial poikilotherms, i.e. organisms whose body
On the quantification of habitability: merging the astrobiological and ecological schools
Abstract In this paper, we connect ideas of the astrobiological and ecological schools to quantify habitability. We show how habitability indexes, devised using the astrobiologically inspired
The Habitable Zone of Inhabited Planets
In this paper we discuss and illustrate the hypothesis that life substantially alters the state of a planetary environment and therefore, modifies the limits of the HZ as estimated for an uninhabited
On the Quantification of Habitability: Current Approaches
TLDR
This chapter outlines general ideas to quantify habitability, starting with a general abiogenesis–biogenesis conceptual model, and presents two indexes devised by us: the Aquatic Primary Habitability for photosynthesis-based ecosystems, and the Chemosynthetic Habitability Index for chemoautotrophy-based ones.
Energy, ecology and the distribution of microbial life
TLDR
It is shown that quantitative knowledge of microbial energy niches (population-specific patterns of energy resource use) can be used to predict variations in the abundance of specific taxa in microbial communities, and proposed that resource ratio theory applied to micro-organisms will provide a useful framework for identifying how environmental communities are organized in space and time.
Superhabitable worlds.
TLDR
It is illustrated how tidal heating can render terrestrial or icy worlds habitable beyond the stellar HZ and why the principle of mediocracy cannot be used to logically explain why Earth should be a particularly habitable planet or why other inhabited worlds should be Earth-like.
The Case for a Gaian Bottleneck: The Biology of Habitability.
TLDR
An alternative Gaian bottleneck explanation for the emergence of life is presented: If life emerges on a planet, it only rarely evolves quickly enough to regulate greenhouse gases and albedo, thereby maintaining surface temperatures compatible with liquid water and habitability.
Quantitative habitability.
TLDR
A framework is proposed for a quantitative approach to studying habitability, and an example involving a comparison of various metabolisms pursued by halophiles is shown to be well on the way to a quantitative habitability analysis.
