Global Change Biology, 2020
The expansion of shrubs across the Arctic tundra may fundamentally modify land–atmosphere interactions. However, it remains unclear how shrub expansion pattern is linked with key environmental drivers, such as climate change and fire disturbance. Here we

Proceedings of the 8th Workshop on Socio-Technical Aspects in Security and Trust, 2018
An organisational requirement of no unauthorised personnel permitted in a restricted area may have a security policy such as all employees must wear identification badges and employees must challenge people who are not wearing a badge. An employee's choice to wear/not wear their badge can be strongly related to how they perceive the security policy ...

Shrub encroachment increases soil carbon and nitrogen stocks in temperate grasslands in China
Land Degradation and Development, 2019Shrub encroachment has significant impacts on carbon (C) and nitrogen (N) dynamics of grassland ecosystems, but, how it influences soil organic C (SOC) and soil total N (STN) stocks of grasslands is not well documented, especially in deep soils. Here, we

Bacterial shrubs, crystal shrubs, and ray-crystal shrubs: bacterial vs. abiotic precipitation
Sedimentary Geology, 1999Hot-water travertine deposits commonly contain shrub-like morphologies, on the centimeter to meter scale, that range from highly irregular forms (bacterial shrubs) to features that display regular geometric patterns (crystal shrubs and ray-crystal crusts).
