As a typical vulnerable ecosystem, alpine steppes can be subject to nonlinear accelerations in degradation, once tipping points are reached or exceeded, and thus far more effort and investment will be needed, to reverse the degraded status of such ecosystems, if effective preventive measures or interventions are not adopted sufficiently early. Thus, detecting early warning signals of tipping events

The Changjiang River estuarine-coastal ocean continuum is a well-studied system that is undergoing significant changes due to human activities and climate change. While research has improved our understanding of its ecological importance, the changing external forces present challenges that require integrated knowledge. Here, we provide a comprehensive summary of the natural and man-made stresses on

Effect of sprouting and corresponding root distribution of the shrub species Eurya japonica on slope stability Catena (IF 6.2) Pub Date : 2024-02-16 Keitaro Yamase, Hidetoshi Ikeno, Norifumi Hotta, Mai Imawaka, Mizue Ohashi, Toko Tanikawa, Chikage Todo, Masako Dannoura, Yasuhiro Hirano
After disturbance sprouts emerge from the ground, generating multi-stemmed plants as they grow, which represents a means of rapidly recovering above ground biomass. We hypothesised that the above- and below ground characteristics would differ depending on the number of stems in individual shrubs, which is likely to compensate for the slope stability of soil reinforcement by plant roots in forests.
