Microalgal blooms are a natural part of the seasonal cycle photosynthetic organisms in marine ecosystems. They key components structure and dynamics oceans thus sustain benefits that humans obtain from these aquatic environments. However, some microalgal can cause harm to other organisms. These harmful algal (HABs) have direct impacts on human health negative influences wellbeing, mainly through their consequences coastal ecosystem services (fisheries, tourism recreation) HABs phenomena, but...
There is increasing concern that accelerating environmental change attributed to human-induced warming of the planet may substantially alter patterns, distribution and intensity Harmful Algal Blooms (HABs). Changes in temperature, ocean acidification, precipitation, nutrient stress or availability, physical structure water column all influence productivity, composition, global range phytoplankton assemblages, but large uncertainty remains about how integration these climate drivers might...
Abstract Aquaculture is the fastest growing food sector globally and protein provisioning from aquaculture now exceeds that wild capture fisheries. There clear potential for further expansion of marine (mariculture), but there are associated risks. Some naturally occurring algae can proliferate under certain environmental conditions, causing deoxygenation seawater, or releasing toxic compounds (phycotoxins), which harm cultured finfish shellfish, also human consumers. The impacts these...
A well-developed deep chlorophyll maximum (DCM) is a prominent feature of the Northwestern Mediterranean during large part year.Data from 7 oceanographic surveys carried out across Catalano-Balearic Sea, between 1982 and 1987, have been used to analyze shortterm (within cruises) seasonal+interannual (between variation several parameters (such as surface DCM concentration, integrated chlorophyll, DCM, nitracline nitrite depths).S~gnificant positlve correlations (p < 0.01) were found depths...
Sea surface temperatures in the world's oceans are projected to warm by 0.4–1.4 °C mid twenty-first century causing many tropical and sub-tropical harmful dinoflagellate genera like Gambierdiscus, Fukuyoa Ostreopsis (benthic algal bloom species, BHABs) exhibit higher growth rates over much of their current geographic range, resulting population densities. The primary exception this trend will be tropics where exceed species-specific upper thermal tolerances (30–31 °C) beyond which slows...
Harmful algal blooms (HABs) produce local impacts in nearly all freshwater and marine systems. They are a global problem that require integrated coordinated scientific understanding leading to regional responses solutions. Given these natural phenomena will never be completely eliminated, improved of HAB dynamics coupled with monitoring ocean observations facilitates new prediction prevention strategies. Regional efforts underway worldwide create state-of-the-art forecasting tools,...
Exposure to harmful algal blooms (HABs) can lead well recognised acute patterns of illness in humans. The objective this scoping review was use an established methodology and the PRISMA (Preferred Reporting Items for Systematic Reviews Meta-Analyses) reporting framework map evidence associations between marine HABs observed both chronic human health effects. A systematic reproducible search publications from 1985 until May 2019 conducted using diverse electronic databases. Following...
Shallow, well--illuminated coastal waters from tropical to temperate latitudes are attractive environments for humans.Beaches and coral reefs have provided lodging food communities centuries.Unfortunately, regions traditionally been threatened by outbreaks of the toxic benthic dinoflagellate Gambierdiscus associated Ciguatera Fish Poisoning.The ciguatoxins produced bioaccumulated in reef fishes responsible most common algal toxin--related illnesses, globally affecting greatest number victims...
The integrated study of ocean health and human is an emerging area increasing global importance. Growing evidences demonstrate that the humans have always been will continue to be, inextricably linked. Our actions towards oceans significantly influence future whole planet and, in turn, our own health. current review these issues arose from a summer school San Sebastian (Spain), 5th-7th June, 2019. An interdisciplinary group researchers discussed key risks (e.g. microbial pollution,...
The need for alternative energy systems like offshore wind power to move towards the Green Deal objectives is undeniable. However, it also increasingly clear that biodiversity loss and climate change are interconnected issues must be tackled in unison. In this paper we highlight farms (OWF) Mediterranean Sea (MS) pose serious environmental risks seabed of many areas due particular ecological socioeconomic characteristics vulnerability semi-enclosed sea. MS hosts a high diversity species...
The ratio of tissue RNA to DNA (R/D) is a widely used index recent growth and nutritional condition in larval juvenile fish. To date, however, no standard technique for measuring nucleic acids has been adopted. Because methodological details can affect the estimate R/D, researchers using different analytical protocols have unable compare ratios directly. Here, we report on results an international interlaboratory calibration 4 spectrofluorometric quantify acids. Replicate sets 5 samples 2...
Blooms of the benthic dinoflagellate Ostreopsis have been related to sporadic acute respiratory symptoms and general malaise in people exposed marine aerosols on some Mediterranean beaches. However, direct link between recurrent blooms health problems has not clearly established. In order establish elucidate connection, we conducted a joint ecology epidemiology study an hot spot. Throughout bloom, which extended from end June until October 2013, 81% human cohort that studied experienced at...
Sea spray aerosol (SSA) formation plays a major role in the climate system. The Antarctic Peninsula (AP) is affected by greatest warming occurring Southern Ocean; changes cryospheric and biological processes are being observed. Whilst there some evidence that organic material produced ice algae and/or phytoplankton high Arctic contributes to SSA, less known about (sympagic) regions. To gain insight into influence of biology biogeochemistry on atmospheric aerosol, we report simultaneous...
ABSTRACT Laboratory experiments were conducted to study the effects of agitation on growth, cell division, and nucleic acid dynamics dinoflagellate Gymnodinium nelsonii Martin. When cultures placed an orbital shaker at 100 rpm, division was prevented, cellular volume increased up 1.5 times that nonperturbed cells, form location nucleus modified, RNA DNA concentrations per 10 those controls. shaking stopped after days, cells divided immediately about 2/3 rate unshaken populations, all altered...
The effect of nitrogen (N) and phosphorus (P) depletion on the cell volume pigment composition marine dinoflagellate Heterocapsa sp. was studied. Cell size increased under both N or P starvation, but change faster when limiting. Quantitatively. deficiency resulted in greater loss than did deficiency, thereby corroborating relationship between synthesis metabolism. It is suggested that pigments primarily stopped at a transcriptional level (from DNA to RNA) limitation translational RNA...

Turbulence has been shown to alter different aspects of the physiology some dinoflagellates. The response appears be species‐specific and dependent on experimental design setup used generate small‐scale turbulence. We examined variability three dinoflagellate species turbulence, following same by Berdalet (1992) Akashiwo sanguinea (Hirasaka) Ge. Hansen et Moestrup (= Gymnodinium nelsonii G. W. Martin). In all experiments, turbulence was generated an orbital shaker at 100 rpm, which...
We present ship-borne and land-based measurements of carbohydrate concentrations patterns in (i) bulk seawater, (ii) sea surface microlayer (SML), (iii) atmospheric size-resolved aerosol particles (0.05–10 μm) collected the Western Antarctic Peninsula. In we find higher combined carbohydrates (CCHO) both particulate (PCCHO, 13–248 μg L–1) dissolved (DCCHO, 14–294 phases than free (DFCHO, 1.0–17 L–1). Moderate enrichment factors are found SML samples (median EFSML = 1.4 for PCCHO, DCCHO,...
