Tracheid buckling buys time, foliar water uptake pays it back - coordination of leaf structure and function in tall redwood trees.

Plant Cell Environ 2022 Jun 23. Epub 2022 Jun 23.

Plant Sciences Department, University of California Davis, Davis, CA, 95616, USA.

Tracheid buckling may protect leaves in the dynamic environments of forest canopies, where rapid intensification of evaporative demand, such as those brought on by changes in light availability, can result in sudden increases in transpiration rate. While treetop leaves function in reliably direct light, leaves below the upper crown must tolerate rapid, thermally driven increases in evaporative demand. Using synchrotron-based X-ray microtomography, we visualized impacts of experimentally induced water-stress and subsequent fogging on living cells in redwood leaves, adding ecological and functional context through crown-wide explorations of variation in leaf physiology and microclimate.

All for One Health and One Health for All: Considerations for Successful Citizen Science Projects Conducting Vector Surveillance from Animal Hosts.

Insects 2022 May 24;13(6). Epub 2022 May 24.

Department of Entomology, Penn State University, University Park, PA 16802, USA.

Many vector-borne diseases that affect humans are zoonotic, often involving some animal host amplifying the pathogen and infecting an arthropod vector, followed by pathogen spillover into the human population via the bite of the infected vector. As urbanization, globalization, travel, and trade continue to increase, so does the risk posed by vector-borne diseases and spillover events. With the introduction of new vectors and potential pathogens as well as range expansions of native vectors, it is vital to conduct vector and vector-borne disease surveillance. Read More
