Simulated Trampling Disturbance Alters Biocrust Microbial Communities and Soil Functions: A Container‐Based Mesocosm Experiment

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Biological soil crusts (biocrusts) are crucial components of dryland ecosystems; however, they are highly vulnerable to anthropogenic disturbances, particularly trampling caused by grazing. To evaluate the impacts of trampling on biocrust structure, microbial communities, and soil functions, we conducted a mesocosm‐based simulated disturbance ...

Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

PTQ10‐based organic photodetectors for visible light detection and their tolerance to impurities

open access: yesPolymer International, EarlyView.
PTQ10‐based organic photodetectors were found to be very sensitive to the presence of Pd(PPh3)4 catalyst traces, impacting the transport properties and light detection capacities. Abstract PTQ10 donor polymer has attracted a lot of interest in organic optoelectronics, particularly in the field of organic photovoltaics, owing to its ease of synthesis ...

Past, present and future of local crop evolution

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Promoting agrobiodiversity is a promising strategy for mitigating the negative effects of climate change on global food security. We highlight the central role evolutionary processes play in harnessing the potential of local crops by integrating genomics, archaeology, ethnobotany and traditional ecological knowledge (TEK).
