Cyanobacteria, also known as blue-green algae, are photosynthetic, aquatic organisms found in fresh, brackish, and marine water around the world (1). Rapid proliferation and accumulation of potentially toxin-producing cyanobacteria characterize one type of harmful algal bloom (HAB). HABs have the potential to cause illness in humans and animals (2,3); however, the epidemiology of these illnesse...
Harmful algal blooms (HABs) cause significant economic and ecological damage worldwide. Despite considerable efforts, a comprehensive understanding of the factors that promote these blooms has been lacking, because the biochemical pathways that facilitate their dominance relative to other phytoplankton within specific environments have not been identified. Here, biogeochemical measurements show...
We investigated the effects of human activities on the pelagic food web structure of nearshore marine ecosystems. Their generic structure was established on the basis of literature review and analyzed by qualitative structural network analysis. Two main issues were addressed: (1) the role of species capable of forming harmful algal blooms (HABs) and red tides (Noctiluca spp.), as well as the ro...
1. Hu, C., B. B. Barnes, L. Qi, and A. A. Corcoran (2015). A harmful algal bloom of Karenia brevis in the northeastern Gulf of Mexico as revealed by MODIS and VIIRS: A comparison. Sensors, 15:2873-2887. 2. Hu, C., Muller-Karger, F.E., Taylor, C.,Carder, K.L., Kelble, C., Johns, E., Heil, C (2005). Red tide detection and tracing using MODIS fluorescence data: A regional example in SW Florida coa...
The incidence of harmful algal blooms (HABs) is increasing in the United States and worldwide. HAB toxins cause a substantial but unquantified amount of human and animal morbidity and mortality from exposures in recreational, commercial, drinking-source and potable waters. HAB biomass and toxins threaten the sustainability of aquatic ecosystems. U.S. Congressional legislation mandated the estab...
The discrimination of harmful algal blooms (HABs) from space would benefit both the capability of early warning systems and the study of environmental factors affecting the initiation of blooms. Unfortunately, there are no published techniques using global monitoring satellite sensors to distinguish the resulting subtle changes in ocean colour, so in situ sampling is needed to identify the spec...
Thread-local allocation buffers (TLABs) are widely used in memory allocators of garbage-collected systems to speed up the fast-path (thread-local allocation) and reduce global heap contention yet at the expense of increased memory fragmentation. Larger TLABs generally improve performance and scalability but only up to the point where more frequent garbage collection triggered by increased memor...
Harmful algal blooms (HABs) degrade water quality and produce toxins. The spatial distribution of HAbs may change rapidly due to variations wind, water currents, and population dynamics. Risk assessments, based on traditional sampling methods, are hampered by the sparseness of water sample data points, and delays between sampling and the availability of results. There is a need for local risk a...
Harmful Algal Blooms (HABs) persist in many water bodies around the world and pose adverse health economic impacts to affected communities. Small Unmanned Aerial Vehicles (UAVs) have recently been applied as a cost-effective tool for HABs monitoring. In this study, two small lakes Southern Illinois (Carbondale Reservoir Campus Lake of University) were monitored using UAVs biomass concentrations...
Harmful algal blooms (HABs) are becoming widely distributed and more frequent, threatening socioecosystems human health. We determined species composition, abundance spatial distribution of dinoflagellate cysts in the upper sediment Oualidia Lagoon located on Atlantic coast Morocco. Sediment samples were collected 2017 at 51 stations, environmental parameters measured together with microphytopl...
