Background and Aims Phytolith studies are still facing numerous challenges regarding the available notions of Si absorption from soil and its deposition in aerial organs. This study shows how plant water availability affects the biosilica content and silicon isotopic composition of phytoliths in sorghum ( Sorghum bicolor ). Methods Phytoliths were extracted from different plant parts of crops grown experimentally in lysimeters...

Assessing the scope and severity of threats is necessary for evaluating impacts on populations to inform conservation planning. Quantitative threat assessment often requires monitoring programs that provide reliable data over relevant spatial and temporal scales, yet such programs can be difficult to justify until there is an apparent stressor. Leveraging efforts of wildlife management agencies to record winter counts of hiber...
