Dinophysis is the main dinoflagellate genus responsible for diarrheic shellfish poisoning (DSP) in human consumers of filter feeding bivalves contaminated with lipophilic toxins. Species this have a worldwide distribution driven by environmental conditions (temperature, irradiance, salinity, nutrients etc.), and these factors are sensitive to climate change. The D. acuminata-complex may contain...

The Arctic Ocean is subject to severe environmental changes, including the massive decline in sea ice due continuous warming many regions. Along with these Ocean's ecosystem affected on various scales. pelagic microbial food web of particular interest, because it determines mass transfer higher trophic levels. In this regard, variations size structure community reflect changes size-dependent bo...

Lake Maggiore is a site of the Long-Term Ecosystem Research (LTER) network, belonging to deep subalpine District in Northern Italy. Studies on physical, chemical, and biological features lake have been performed continuously since 1980s. The recovered from eutrophication reaching present oligotrophic condition. In last decade, climate change represents main driving factor for long-term evolutio...

we studied the role of nutrients on various aspects of the periphyton community in artificialstreams. dry mass, ash-free dry mass, chlorophyll a and biovolume of the periphyton community weremeasured under 3 different nutrient regimes, including one from natural streams as a control and twowhich were enriched with n and n+p. results of this experiment indicate that the standing crop of theperip...

Floristic studies indicate the abundance of microalgae in northern boreal peatlands, but we know relatively little about their ecology or how they will respond to changes in environmental conditions expected in this region as climate changes. We examined changes in algal community structure at sites exposed to a long-term water-table manipulation, including drought (lowered water-table treatmen...

The ability to count bacteria associated with reef-building corals in a rapid, reliable, and cost-effective manner has been hindered by the viscous and highly autofluorescent nature of the coral mucus layer (CML) in which they live. We present a new method that disperses bacterial cells by trypsinization prior to 4',6-diamidino-2-phenylindole (DAPI) staining and quantification by epifluorescenc...
