We investigated how Half-Against-Half Support Vector Machine (HAH-SVM) and Half-Against-Half kNearest Neighbour (HAH-KNN) methods succeed in the classification of the benthic macroinvertebrate images. Automated taxa identification of benthic macroinvertebrates is a slightly researched area and in this paper HAH-KNN was for the first time applied to this application area. The main problem, when ...

In coastal environments, the supratidal zone bridges marine and terrestrial ecosystems and is important for energy exchange. However, it is also subject to extensive anthropogenic disturbance, such as armoring of shorelines. Shoreline armoring is extensive along many coasts, but the impacts on biota are comparatively unknown. Between 2000 and 2002, paired and synoptic sampling regimes were empl...

Water is one of the most essential factors for civilization, and also among the most important items in the new world order due to its unrenewable feature. In this regard, developed countries have continually been monitoring and classifying their water. For this reason, a number of EU countries have developed a national water quality system, considering characteristic structure of their own riv...

Background: Water quality monitoring is vital for the sustainable conservation of water resources. Benthic macro invertebrates have been documented as best indicators serving a link in aquatic food web. The present work was carried out at Dikhu River, Mokokchung, Nagaland. Methods: analysis samples done by adopting standard methods and compared against W.H.O. 1995 drinking standards water. macr...

Analysis of patterns of temporal variation in community dynamics was conducted by combining two unsupervised artificial neural networks, the Adaptive Resonance Theory (ART) and the Kohonen network. The field data used as input for training represented monthly changes in density and species richness in selected taxa of benthic macroinvertebrates collected in the Suyong River in Korea from Septem...

Land-use alterations and pesticide run-offs are among the main causes for impairment in agricultural areas. We evaluated the influence of different land-uses (forest, pasture and intensive agriculture) on the water quality and on benthic macroinvertebrate assemblages on three occasions: in the dry season, wet season and at the end of the wet season. Macroinvertebrates responded to this gradient...

Stream types determined according to altitude, slope and alkalinity in six different hydrobiogeographic regions of Türkiye were taken as the basis study. In line with European Water Framework Directive, a macroinvertebrate based multimetric method was tested for Turkish rivers potential assessment. this study, benthic data (3502 samples obtained from 1925 stations reference points) used create ...

Body size is a key trait of species, populations, and organisms; it relates to abundance, home range, metabolic rates, stressors. As reported by Damuth’s law, the relationship between body abundance negative with slope value −0.75. In aquatic ecosystems, particularly for benthic macroinvertebrates, deviates from expected This variation may depend on abiotic biotic factors as well methods that a...

Abstract Compliance with the Water Framework Directive has not yet been met by Albania, and further efforts are needed to achieve this goal, including implementation of an extensive programme monitoring surface groundwater bodies. Benthic macroinvertebrates integrated element whose results being used assess achievement objectives. This study carried out strictly following protocols methodologie...
