Wetting and drying cycles are widely recognised as driving aquatic macroinvertebrate zooplankton production, providing prey recruitment opportunities for fish in floodplain river systems. Conversely, invertebrate consumption of fishes features less frequently food web studies. We used two sources information: a) the finding an intact eel skeleton exceedingly high number diving beetles (Cybister...

An unstructured finite volume numerical model is presented here for simulating shallow-water flows with wetting and drying fronts. The model is based on the Green’s theorem in combination with Chorin’s projection method. A 2-order upwind scheme coupled with a Least Square technique is used to handle convection terms. An Wetting and drying treatment is used in the present model to ensures the to...

Structure-dependent colour is caused by the interaction of light with photonic crystal structures rather than pigments. The elytra of longhorn beetles Tmesisternus isabellae appear to be iridescent green in a dry state and turn to red when exposed to humidity. Based on the hygroscopic colouration of the longhorn beetle, we have developed centimeter-scale colorimetric opal films using a novel se...
