    Nonlinear forecasting of intertidal shoreface evolution (2015)
    American Institute of Physics (AIP)
    In: Chaos
    Details
    Publication Date: 2015-10-01
    Description: Natural systems dominated by sediment transport are notoriously difficult to forecast. This is particularly true along the ocean coastline, a region that draws considerable human attention as economic investment and infrastructure are threatened by both persistent, long-term and acute, event driven processes (i.e., sea level rise and storm damage, respectively). Forecasting the coastline's evolution over intermediate time (daily) and space (tens of meters) scales is hindered by the complexity of sediment transport and hydrodynamics, and limited access to the detailed local forcing that drives fast scale processes. Modern remote sensing systems provide an efficient, economical means to collect data within these regions. A solar-powered digital camera installation is used to capture the coast's evolution, and machine learning algorithms are implemented to extract the shoreline and estimate the daily mean intertidal coastal profile. Methods in nonlinear time series forecasting and genetic programming applied to these data corroborate that coastal morphology at these scales is predominately driven by nonlinear internal dynamics, which partially mask external forcing signatures. Results indicate that these forecasting techniques achieve nontrivial predictive skill for spatiotemporal forecast of the upper coastline profile (as much as 43% of variance in data explained for one day predictions). This analysis provides evidence that societally relevant coastline forecasts can be achieved without knowing the forcing environment or the underlying dynamical equations that govern coastline evolution.

    Emerging marine diseases--climate links and anthropogenic factors (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-09-25
    Description: Mass mortalities due to disease outbreaks have recently affected major taxa in the oceans. For closely monitored groups like corals and marine mammals, reports of the frequency of epidemics and the number of new diseases have increased recently. A dramatic global increase in the severity of coral bleaching in 1997-98 is coincident with high El Nino temperatures. Such climate-mediated, physiological stresses may compromise host resistance and increase frequency of opportunistic diseases. Where documented, new diseases typically have emerged through host or range shifts of known pathogens. Both climate and human activities may have also accelerated global transport of species, bringing together pathogens and previously unexposed host populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harvell, C D -- Kim, K -- Burkholder, J M -- Colwell, R R -- Epstein, P R -- Grimes, D J -- Hofmann, E E -- Lipp, E K -- Osterhaus, A D -- Overstreet, R M -- Porter, J W -- Smith, G W -- Vasta, G R -- 1PO1 ES09563/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1999 Sep 3;285(5433):1505-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecology and Evolutionary Biology, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10498537" target="_blank"〉PubMed〈/a〉

    Notes: Abstract Two urease-positiveVibrio spp. were isolated from a brown shark (Carcharhinus plumbeus) that died in captivity at a national aquarium. Morphological, biochemical, and molecular genetic studies revealed one of the isolates to beV. damsela; the other isolate was unique and has been classified asV. carchariae sp. nov. BothV. damsela andV. carchariae were found to be virulent for spiny dogfish (Squalus acanthias), causing death in less than 18 hours after intraperitoneal injection of ca. 4×106 cells.V. damsela was strongly cytotoxic for Y1 adrenal cell monolayers;V. carchariae exhibited weak cytotoxicity for Y1 cells.V. damsela contained cryptic plasmids and both isolates were urease positive.V. carchariae was able to utilize urea as sole source of carbon and nitrogen.

    Bacterial bioconcentration of chlorinated hydrocarbon insecticides from aqueous systems (1975)

    Topics: Biology
    Notes: Abstract The prevalence of chlorinated hydrocarbon insecticide uptake by chemoorganotrophic bacteria has been investigated. Thirteen bacterial species were observed to sorb and concentrate (bioconcentratc)α-chlordane,β-chlordane, dieldrin, heptachlor epoxide, and lindane from aqueous systems. Bioconcentration, as expressed by the ratio of cellular insecticide in ng/mg (dry wt) to supernatant insecticide in ng/μl, ranged from 10 for lindane byEnterobacter aerogenes to a high of 55,900 forβ-chlordane byCaulobacter vibrioides var.limonus. Amounts of cellular chlorinated hydrocarbon insecticides (CHI) detected and the bioconcentration ratios were observed to have the following order in magnitude:α- orβ-chlordane 〉 dieldrin 〉 heptachlor epoxide 〉 lindane. This decreasing order was the inverse of reported water solubilities for the CHI and the inverse relationship was mathematically defined. The CHI were not easily removed from cells by washing (desorbing) and desorption was directly proportional to insecticide water solubility. Uptake of the CHI was rapid, near-maximum amounts being sorbed within 15 min, and pH 7 appeared optimal for bioconcentration as examined over the range pH 6 to 8. Implications of this investigation are that bioconcentration of CHI by bacteria might serve as a means of introducing these toxic compounds into aquatic food chains and that the bioconcentration phenomenon might lend itself as a treatment procedure for the intentional removal of residual CHI from water supplies and wastewater.

    Experimental infection of lemon sharks, Negaprion brevirostris (Poey), with Vibrio species (1985)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish diseases 8 (1985), S. 0

    Notes: Abstract Healthy lemon sharks, Negaprion brevirostris (Poey), were inoculated with Vibrio carchariae and V. damsela, two vibrios known to cause disease in other shark species. Vibrio damsela was not recovered from the inoculated sharks; V. carchariae infected the healthy lemon sharks, but did not produce clinically observable disease. However, histological evaluation revealed active splenic and hepatic disease with Gram-negative bacteria found in association with mononuclear cells. When the experiment was repeated with a physiologically compromised lemon shark, V. carchariae was lethal for the test animal, but V. damsela was again cleared. Vibrio carchariae was also isolated from skin lesions of a lemon shark infested with monogeneans (Dermophthirius nigrellii). Histological evidence indicated that this shark died of protozoan infection. Thus, lemon sharks are susceptible to infection with V. carchariae which can cause subclinical disease in otherwise healthy specimens. We suggest that D. nigrellii may act as a vector of V. carchariae and that stress plays a role in the clinical manifestation of this disease.

    Survival and viability of nonculturableEscherichia coli andVibrio cholerae in the estuarine and marine environment (1982)

    Notes: Abstract Plating methods for estimating survival of indicator organisms, such asEscherichia coli, and water-borne pathogens includingVibrio cholerae, have severe limitations when used to estimate viable populations of these organisms in the aquatic environment. By combining the methods of immunofluorescent microscopy, acridine orange direct counting, and direct viable counting, with culture methods such as indirect enumeration by most probable number (MPN) estimation and direct plating, it was shown that bothE. coli andV. cholerae undergo a “nonrecoverable” stage of existence, but remain viable. Following 2-week incubations in saltwater (5–25%o NaCl) microcosms, total counts, measured by direct microscopic examination of fluorescent antibody and acridine orange stained cells, remained unchanged, whereas MPN estimates and plate counts exhibited rapid decline. Results of direct viable counting, a procedure permitting estimate of substrate-responsive viable cells by microscopic examination, revealed that a significant proportion of the nonculturable cells were, indeed, viable. Thus, survival of pathogens in the aquatic environment must be re-assessed. The “die-off” or “decay” concept may not be completely valid. Furthermore, the usefulness of the coliform and fecal coliform indices for evaluating water quality for public health purposes may be seriously compromised, in the light of the finding reported here.

    Notes: Abstract SeveralVibrio spp. cause disease in marine fish populations, both wild and cultured. The most common disease, vibriosis, is caused byV. anguillarum. However, increase in the intensity of mariculture, combined with continuing improvements in bacterial systematics, expands the list ofVibrio spp. that cause fish disease. The bacterial pathogens, species of fish affected, virulence mechanisms, and disease treatment and prevention are included as topics of emphasis in this review.
