The planktonic and benthic microbial communities in eight hypersaline evaporation ponds of Eilat, Israel, ranging in salinity between 58 and 329 g l(-1), were studied by microscopic methods. Marked shifts in the species composition of phototroph[...]

Natural populations of planktonic Synechococcus spp. exhibit diel variations in abundance and frequency of dividing cells (FDC) during the warm seasons (> 25A degrees C) in coastal water of the western subtropical Pacific ocean. We hypothesized [...]

The strong invasive freshwater mysid Limnomysis benedeni, a detritivorous-herbivorous feeder, has a preference for small food particles, but also feeds on leaf litter. Here, we tested whether leaf litter consumption by L. benedeni depends on the[...]

Light intensity preferences of Procambarus clarkii (Girard, 1852) were evaluated in an indoor fiber glass trough, consisting of five equal length (4 m) zones with light intensities varying from dark to 1,000 lux (L), situated at the 'Las Vegas d[...]

Eucypris virens is a freshwater ostracod in which both sexual reproduction and parthenogenesis occur. Sympatric coexistence of both reproductive modes is known in zones of overlap. This renders the species a potentially valuable model organism t[...]

The importance of cephalopods in marine ecosystems is well recognized as they serve as important predators and prey in many food chains. During a 1-year period, cuttlefish were monthly sampled in five areas throughout the Sado estuary, and the s[...]

Many invasive species show temporal variations in abundances, such as seasonal cycles and medium to long term variations. The effects of invasive species on native assemblages have, however, mainly been investigated during the maximum abundance [...]

Diatoms have been routinely used to monitor the ecological status of French rivers. Since 2000, this monitoring has been carried out to comply with the Water Framework Directive. Ecoregions corresponding to the aquatic fauna and flora of rivers [...]

A current practice of marine aquaculture is to integrate fish with low-trophic-level organisms (e.g. molluscs and/or algae) during farming to minimise effects of cultivation on the surrounding environment and to potentially increase economic inc[...]

The determination of the history and causes of recent eutrophication and intensified thermal stratification in Lake Victoria is still hampered by the sparsity of paleolimnologic coverage of the enormous lake. Five new diatom records from Ugandan[...]
