The Astrophysical Journal Letters, 2023 Climate modeling has shown that tidally influenced terrestrial exoplanets, particularly those orbiting M-dwarfs, have unique atmospheric dynamics and surface conditions that may enhance their likelihood to host viable habitats.

Habitability of extrasolar planets and tidal spin evolution
, 2011 Stellar radiation has conservatively been used as the key constraint to planetary habitability. We review here the effects of tides, exerted by the host star on the planet, on the evolution of the planetary spin. Tides initially drive the rotation period

Catastrophic Declines in Wilderness Areas Undermine Global Environment Targets.
Current Biology, 2016 Humans have altered terrestrial ecosystems for millennia [1], yet wilderness areas still remain as vital refugia where natural ecological and evolutionary processes operate with minimal human disturbance [2-4], underpinning key regional- and planetary ...

Coupled Above‐ and Belowground Ecosystem Stability Worldwide
Advanced Science, EarlyView.Are the worlds above and below our feet in sync? This global exploration reveals an entangled fate between above‐ and belowground ecosystem stability. It identifies arid regions as hotspots for this coupling and highlights temperature stability as a vital safeguard for maintaining ecosystem balance across our warming planet.

Crater Retention Timescales of Brain Coral Terrain Record Past Climatic Change on Mars
The Planetary Science JournalGlacial landforms on Mars offer an opportunity to decipher the planet’s recent climate history. We used crater size frequency distributions of brain coral terrain on concentric crater fill, lobate debris aprons, and lineated valley fill, all of which ...

The Final Ascent: from refuges to ruins in a warming world [PDF]
Research Ideas and OutcomesMountains exemplify how climate change transforms long-standing refuges into zones of loss. As species track suitable climates upslope, they confront absolute ecological limits.

High Stellar FUV/NUV Ratio and Oxygen Contents in the Atmospheres of Potentially Habitable Planets [PDF]
, 2013 Recent observations of several planet-hosting M dwarfs show that most have FUV/NUV flux ratios 1000 times greater than that of the Sun. Here we show that the atmospheric oxygen contents (O2 and O3) of potentially habitable planets in this type of UV ...

The New Titan Planetary Climate Model. II. Titan’s Haze and Cloud Cycles
The Planetary Science JournalObservations of Titan have long revealed the presence of seasonal cycles, including haze, clouds, and gases. The lack of information on the different processes that govern these cycles prevents us from understanding all the phenomena taking place in ...
