The spatiotemporal changes in surface water area (SWA) the basins of Northeast China have far-reaching impacts on their economic, agricultural, and social development ecological sustainability. However, long-term variation characteristics bodies basin its main driving factors are still unclear. Based global dataset, combined with Meteorological Vegetation Normalized Index (NDVI) datasets, this ...

An estuarine wetland is an area of high ecological productivity and biodiversity, it also anthropic activity hotspot area, which concern. The wetlands in areas have suffered declines, had remarkable impacts. land use changes, especially loss, were studied based on Keyhole Landsat images the Liao River delta from 1962 to 2016. dynamics ecosystem service values (ESVs), suitable habitat for birds,...

Grande Riviere Beach in Trinidad and Tobago is an important nesting site in the Caribbean for the Critically Endangered leatherback sea turtle, Dermochelys coriacea. Community members were concerned that beach erosion and seasonal river flooding were destroying many of the nests deposited annually and thought that a hatchery was a possible solution. Over the 2001 turtle nesting season, the Inst...

This paper presents three hybrid metaheuristic algorithms that further improve the two hybrid differential evolution (DE) metaheuristic algorithms described in Liao [1]. The three improved algorithms are: (i) MDE′–HJ, which is a modification of MA–MDE′ in Liao [1] by replacing the random walk with direction exploitation local search with the Hooke and Jeeves (HJ) method; (ii) MDE′–IHS–HJ, which...

Floods of high magnitude are one of the major problems in the north-eastern region of India. Heavy flooding causes abrupt changes in the flow pattern of the rivers. The present paper deals with the study of three northern bank tributaries of the Brahmaputra river, namely Jia-Bhareli, Puthimari and Pagladiya. The river Brahmaputra shows significant amount of erosion and deposition in the basin. ...

The river carpsucker, Carpiodes carpio, was collected in the Missouri River bordering eastern Nebraska in 1961 and 1962. During and preceding the study period the course of the river was being altered to promote commercial barge traffic. These alterations resulted in numerous cutoff lakes and chutes many of which were left open to the river at their downstream ends. Collections were made both h...

Range expansion of obligate freshwater fishes in the Cape Floristic Region (CFR) of South Africa has mostly been attributed to river capture events and confluence of rivers following sea-level regression. The role of low drainage divides and interbasin water transfers has received less attention. This study analyzed mitochondrial and nuclear DNA sequences to assess the processes that could have...

The SIGNAL biotic index for river macroinvertebrates, originally developed and tested in eastern Australia, was revised for application to the entire continent. Macroinvertebrate survey data from the National River Health Program were used to set grade numbers between 1 and 10 to represent the water-quality sensitivities of 210 taxa. Grades were assigned at the taxonomic levels customarily used...
