Studies of plant phenology have been performed predominantly with terrestrial species and rarely so aquatic communities. Such plants are fundamental for the ecosystems, representing a valuable source resources when they scarce in environments fauna. help to understand reproduction rhythms communities provide support management conservation.

Climate change is expected to increase fire activity, which has the potential accelerate climate-induced shifts in species composition and distribution boreal-temperate ecotone. Wildfire can kill resident trees, thus provide establishment opportunities for migrating tree species. However, role of size its interactions with varied life-history attributes driving not understood. Future regimes co...

The Elements of Metacommunity Structure (EMS) framework gives rise to important ecological insights through the distinction of metacommunities into several different idealised structures. We examined the EMS in assemblages occupying a low-mountain river system in central Germany, sampled over three consecutive years. We compared the idealised distributions of assemblages in both the riparian fl...

Land-use change alters soil carbon (C) storage in terrestrial ecosystem through affecting respirations (Rs). However, the long-term effects of land-use on Rs are poorly understood. We undertook a field experiment to examine Rs. The types included grazed grassland (GGL), enclosed (EGL), continuous cropland (CCL), rotation (RCL) and abandoned (ACL) an alpine agro-pastoral ecotone Qinghai-Tibetan ...
