Changes in environmental conditions regulate the biodiversity of planktonic microeukaryotes mediated by the dispersal-selection relationships in river: an example of the Beipan River, Guizhou, China.

River planktonic microeukaryotes (phytoplankton and zooplankton) underpin aquatic ecosystem function, yet how environmental change regulates their biodiversity via assembly mechanisms remains poorly understood. Using eDNA metabarcoding along China's Beipan River, partitioned by a barrier dam into environmentally heterogeneous upstream and stable downstream regions, we assessed plankton diversity and the roles of dispersal and environmental selection. Phytoplankton exhibited higher alpha- and beta-diversity than zooplankton, attributed to stronger dispersal but weaker selection.

A waterproof and breathable cellulosic composite with thermal management inspired by penguins.

Temperature is paramount for human body, contributing to a growing demand for enhanced thermal comfort in wearable textiles. However, it is still a major challenge to prepare multifunctional thermal comfort materials with integrated insulation strategies. The Antarctic penguin uses its feathers to maintain body temperature by three different functional layers, namely photothermal conversion layer, thermal insulation layer and infrared reflective layer.
