• Amphicryptophytes — An ecological term used to designate a group of amphibious plants (cryptophytes) whose renewal organs, the wintering buds, are structurally protected underwater or underground, depending on seasonal fluctuations of the aquatic level; plants adapted to wetlands and floodplains, capable of functioning alternatively as helophytes (marsh plants) or as geophytes (terrestrial plants with underground bulbs/rhizomes).
• Oxbow lake — A regional or archaic form used to describe an old riverbed abandoned by a watercourse, an oxbow lake turned into a temporary pond, or a natural floodable excavation formed by the structural diversion of a main river. In a broader hydrological sense, archenea represents a lacustrine micro-ecosystem specific to floodplains, characterized by organic silt accumulations and dense hydrophilic vegetation.
• Baicheng — A prefecture-level city located in the northwestern part of Jilin province, People's Republic of China, bordering Heilongjiang and Inner Mongolia. Etymologically, its name translates to 'White City', derived from its historical Mongolian name (Chaganhot). The region features vast steppe plains and is internationally recognized for major wetland nature reserves like Momoge.
