Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Habitability in 4D: Predicting the Climates of Earth Analogs across Rotation and Orbital Configurations

open access: yesThe Astrophysical Journal
Earth-like planets in the circumstellar habitable zone (HZ) may have dramatically different climate outcomes depending on their spin–orbit parameters, altering their habitability for life as we know it.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Effects of Transient Stellar Emissions on Planetary Climates of Tidally Locked Exo-Earths

open access: yesThe Astronomical Journal
Space weather events in exoplanetary environments sourced from transient host star emissions, including stellar flares, coronal mass ejections, and stellar proton events, can substantially influence a planet's habitability and atmospheric evolution ...

The influence of circadian variables on ecotoxicology metabolomics

open access: yesBiological Reviews, EarlyView.
ABSTRACT Ecotoxicologists are using metabolomics increasingly to gain insight into toxicological mechanisms and sublethal effects of chemical exposures. Metabolomics offers a sensitive multi‐parameter approach that can detect biochemical responses not obvious using apical and behavioural endpoints.

A Secular Solar System Resonance that Disrupts the Dominant Cycle in Earth’s Orbital Eccentricity (g 2 − g 5): Implications for Astrochronology

open access: yesThe Astronomical Journal
The planets’ gravitational interaction causes rhythmic changes in Earth’s orbital parameters (also called Milanković cycles), which have powerful applications in geology and astrochronology.

Planetary volatiles [PDF]

open access: yes, 1983
Initial and present volatile inventories and distributions in the Earth and other planets, meteorites, and comets; observational evidence on the time history of volatile transfer among reservoirs; and volatiles in planetary bodies, their mechanisms of ...
