Toxic cyanobacterial blooms are an increasing problem in the lower Laurentian Great Lakes. To better understand their occurrence and distribution, samples for particulate toxin analysis were collected from more than 140 New York Lakes including Lakes Erie, Champlain and Ontario. Microcystins were of most importance and were detected in nearly 50% of the samples. Anatoxin-a, cylindrospermopsin a...

To establish the influence of phytoplankton blooms on the cycling of dissolved and particulate species of organic carbon and nitrogen, we conducted a field study during a series of blooms in a coastal embayment on Shelter Island, NY. Using cross-flow filtration, we collected highand low-molecular-weight (HMW and LMW) dissolved organic matter (DOM), along with particulate organic matter (POM). T...

a r t i c l e i n f o Phytoplankton blooms, in their pivotal position in pelagic seasonal succession require precise classification criteria in order to evaluate such parameters as bloom start, bloom timing, bloom maximum and growth rates. Such bloom parameters are linked directly to species and bloom specific features. Currently the phytoplankton bloom concept, though intuitively clear, lacks ...

Advected cyanobacteria, algal blooms and cyanotoxins have been increasingly detected in freshwater ecosystems. This review gives an insight into the present state of knowledge on taxonomy, dynamics, toxic effects, human ecological health implications East African Community lakes. The major toxigenic microalgae lakes include Microcystis, Arthrospira, Dolichospermum, Planktolyngbya Anabaenopsis s...

In the late summers of 1993 and 2007, phytoplankton communities in Allatoona Lake shifted from typically diverse assemblages to near monospecific blooms of small cell-size species (a 0.5 X 2 μm cyanobacterium and a 2.5 X 15 μm diatom, respectively). These changes resulted in major increases in the amount of flocculating chemicals used to treat drinking water. Water temperatures in the epilimnio...

The Web of Data currently coming into existence through the Linked Open Data (LOD) effort is a major milestone in realizing the Semantic Web vision. However, the development of applications based on LOD faces difficulties due to the fact that the different LOD datasets are rather loosely connected pieces of information. In particular, links between LOD datasets are almost exclusively on the lev...

Prymnesium parvum is a toxin-producing haptophyte that causes harmful algal blooms globally, leading to large-scale fish kills that have severe ecological and economic implications. For the model haptophyte, Emiliania huxleyi, it has been shown that large dsDNA viruses play an important role in regulating blooms and therefore biogeochemical cycling, but much less work has been done looking at v...

The trouble began for Toledo, Ohio, in the spring of 2014, when extreme storms washed an unusually high pulse of nutrients into Lake Erie. By late summer, a massive bloom of blue-green algae, otherwise known as cyanobacteria, had shut down the city’s drinking water system. Powered by nutrients from agricultural runoff and the warm, calm summer waters, the algae spread across the lake and slowly...
