  1. 1. Trophic complexity of zooplankton–cyanobacteria interactions in the Baltic Sea : Insights from molecular diet analysis

    Författare :Nisha H. Motwani; Elena Gorokhova; Jakob Walve; Catherine Legrand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bloom-forming filamentous cyanobacteria; diazotrophs; picocyanobacteria; zooplankton; grazing; molecular diet analysis; stable isotopes; biochemical indices; Marine Ecology; marin ekologi;

    Sammanfattning : Blooms of nitrogen fixing cyanobacteria (NFC) occur in many freshwater and marine systems, including the Baltic Sea. By fixing dissolved nitrogen, they circumvent general summer nitrogen limitation, while also generating a supply of novel bioavailable nitrogen for non-diazotrophic primary producers and ultimately supporting secondary production.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; β-N-methylamino-L-alanine; BMAA; cyanobacteria; Baltic Sea; blooms; neurotoxin; neurodegenerative diseases; amyotrophic lateral sclerosis; ALS; nitrogenase; nitrogen fixation; Plant Physiology; växtfysiologi;

    Sammanfattning : β-N-methylamino-L-alanine (BMAA) is one of the more recently discovered bioactive compounds produced by cyanobacteria. BMAA is a non-protein amino acid reported present in human brain tissues of patients deceased from a neurodegenerative disease, such as Alzheimer´s disease or amyotrophic lateral sclerosis (ALS).
