The effects of physiological integration on clonal plants growing in aquatic and terrestrial habitats have been extensively studied, but little is known about the role in the extension of amphibious clonal plants in the heterogeneous aquatic-terrestrial ecotones, especially when the water environments are polluted by heavy metals. Ramets of the amphibious clonal herb Alternanthera philoxeroides...

Dear Editor, This letter is concerned with visual feedback disturbance rejection control for an amphibious bionic stingray subject to actuator saturation internal and external disturbances. A method designed a dynamic nonlinear system on yaw angle of the via finite-time extended-state-observer, which proved achieve stability Lyapunov method. Finally, simulation results verify effectiveness

We present the leaf anatomy of seven amphibious species of Aeschynomene L. (Papilionoideae, Leguminosae), interpreting their structures and ecological functions, and also, providing information on which their taxonomy can be based, especially of morphologically similar species. We evaluated Aeschynomene americana, A. ciliata, A. evenia, A. denticulata, A. fluminensis, A. rudis and A. sensitiva....
