Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

open access: yesJournal of Raman Spectroscopy, EarlyView.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

The Detection and Characterization of Extrasolar Planets

open access: yesChallenges, 2014
We have now confirmed the existence of > 1800 planets orbiting stars other thanthe Sun; known as extrasolar planets or exoplanets. The different methods for detectingsuch planets are sensitive to different regions of parameter space, and so, we are ...

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them

open access: yesPeople and Nature, EarlyView.
Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

Building a Geochemical View of Microbial Salt Tolerance: Halophilic Adaptation of Marinococcus in a Natural Magnesium Sulfate Brine

open access: yesFrontiers in Microbiology, 2018
Current knowledge of life in hypersaline habitats is mostly limited to sodium and chloride-dominated environments. This narrow compositional window does not reflect the diversity of brine environments that exist naturally on Earth and other planetary ...
