Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Degassing of CO2 triggers large-scale loss of helium from magma oceans

Communications Earth & Environment
The moon-forming impact caused widespread melting and vaporization of the proto-Earth, leading to the formation of a protolunar disk1,2. Volatile elements trapped in the inner parts of the disk condensed together with heavier elements into a global magma

The Microbial Community of a Terrestrial Anoxic Inter-Tidal Zone: A Model for Laboratory-Based Studies of Potentially Habitable Ancient Lacustrine Systems on Mars

Microorganisms, 2018
Evidence indicates that Gale crater on Mars harboured a fluvio-lacustrine environment that was subjected to physio-chemical variations such as changes in redox conditions and evaporation with salinity changes, over time.

The Carbonate Geochemistry of Enceladus' Ocean

Geophysical Research Letters, 2020
The plume composition at Enceladus contains clues about conditions and processes in the interior. We present new geochemical interpretations of Cassini mass spectrometry data from the plume gas and salt‐rich ice grains.

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, EarlyView.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

Symbolic or Substantive Action: Intent, Effort, and Results

Business Strategy and the Environment, EarlyView.
ABSTRACT Many firms have made ambitious climate pledges since the Paris Agreement of 2015. These pledges may be symbolic or substantive, but the literature is fragmented in defining these two terms. We propose a conceptual framework with three frames to delineate symbolic from substantive action: Intent—underlying motivations for engaging in climate ...

Prolonged Multi‐Phase Magmatism Due To Plume‐Lithosphere Interaction as Applied to the High Arctic Large Igneous Province

Geochemistry, Geophysics, Geosystems
The widespread High Arctic Large Igneous Province (HALIP) exhibits prolonged melting over more than 50 Myr, an observation that is difficult to reconcile with the classic view that large igneous provinces (LIPs) originate from melting in plume heads ...

Dynamics of Y dwarf atmospheres

Astronomy & Astrophysics
Context. The global circulation regime of the coolest class of brown dwarfs, known as the Y dwarfs, remains largely unexplored. Aims. We aim to investigate the interplay between convection, rotation, and cloud thermal feedback through a selected sample ...
