Algal extracellular release in river-floodplain dissolved organic matter: response of extracellular enzymatic activity during a post-flood period
River-floodplain systems are susceptible to rapid hydrological events. Changing hydrological connectivity of the floodplain generates a broad range of conditions, from lentic to lotic. This creates a mixture of allochthonously and autochthonously derived dissolved organic matter (DOM). Autochthonous DOM, including photosynthetic extracellular release (PER), is an important source supporting bac...
متن کاملAmphibian Abundance and Detection Trends During a Large Flood in a Semi-Arid Floodplain Wetland
—Amphibian abundance and occupancy are often reduced in regulated river systems near dams, but comparatively little is known about how they are affected on floodplain wetlands downstream or the effects of actively managed flows. We assessed frog diversity in the Macquarie Marshes, a semi-arid floodplain wetland of conservation significance, identifying environmental variables that might explain...
متن کاملOrganic Matter Processing in Tropical Streams
Organic matter derived from many sources provides a basis for stream food webs. In terms of weight, leaves from the surrounding land constitute the largest allochthonous source of energy for stream consumers, but other items, including fruits, flowers, wood and twigs, and terrestrial insects, are also important. Timing of allochthonous inputs can vary markedly due to the phenology of the ripari...
متن کاملStruggle in the flood: tree responses to flooding stress in four tropical floodplain systems
BACKGROUND AND AIMS In the context of the 200th anniversary of Charles Darwin's birth in 1809, this study discusses the variation in structure and adaptation associated with survival and reproductive success in the face of environmental stresses in the trees of tropical floodplains. SCOPE We provide a comparative review on the responses to flooding stress in the trees of freshwater wetlands i...
متن کاملcritical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
