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...

Studies designed to measure anthropogenic impacts on marine benthic communities depend on the ability of taxonomists to consistently discriminate, identify, and count benthic organisms. To quantify errors and discrepancies in identification and enumeration, 20 samples were completely reprocessed by another one of four participating laboratories. Errors were detected in 13.0% of the data records...

Globally, lakes are warming and browning with ongoing climate change. These changes significantly impact a lake's biogeochemical properties all organisms, including invertebrate consumers. The effects of these essential to understand, especially during critical periods after before the growing season, that is, autumn spring, which can determine composition consumer community. In this study, we ...

Through systematic Reef Life Survey censuses of rocky reef fishes, invertebrates and macroalgae at eight marine reserves across northern New Zealand and the Kermadec Islands, we investigated whether a system of no-take marine reserves generates consistent biodiversity outcomes. Ecological responses of reef assemblages to protection from fishing, including potential trophic cascades, were assess...

It is possible to increase the sampling resolution and the available information on zooplankton populations by applying acoustic sampling techniques. Knowledge of an organism’s acoustic target strength (TS) is critical for translating acoustic data into meaningful biological information, such as numerical abundance. We have taken several approaches to evaluate the acoustic TS of Mysis relicta, ...

Salmonids frequently adapt their feeding and movement strategies to cope with seasonally fluctuating stream environments. Oncorhynchus mykiss tend drift-forage in higher velocity habitat than other salmonids, yet presence streams low drift suggests behavioral flexibility. We combined 3D videogrammetry measurements of invertebrate hydraulics investigate the drivers O. foraging mode during season...

Many coastal habitats are being substantially altered by introduced plants. In San Francisco Bay, California, USA, a hybrid form of the eastern cordgrass Spartina alterniflora is rapidly invading open mudflats in southern and central sections of the Bay, altering habitat, reducing macrofaunal densities, and shifting species composition. The invasion has resulted in significant losses of surface...
