University, Ann Arbor, MI, 48109. Persistent Organic Pollutants on Microplastic Debris from Great Lakes. Microplastic pollution is becoming a fast growing problem in our environment. Our society is highly dependent on plastic products; from large industrial goods to the smallest plastic bags one gets from the stores, can all be potential hazards to the environment if they are not disposed properly. These products are not being recycled properly and they are polluting different water bodies and also other natural environments. Microplastic pollution can be highly catastrophic to the aquatic organisms because of the known potential to adsorb persistent organic pollutants, POPs, which can affect the human race. The problem is not being emphasized as it should be compared to its disastrous impact. The objective of this research is to provide an assessment of the pollution caused by microplastic debris in the Great Lakes waters by adsorption of toxic compounds. The preliminary results presented are from 44 samples from surface water (33 samples) and sediments (11 samples) collected from May to August, 2014. The plastic debris collected was classified by color, size, and chemical composition of the synthetic polymer. Keywords: Microplastics, POPs, PCBs, Freshwater, PAHs.

Lake Characteristics that Affect Biomagnification of Mercury in Michigan's Upper Peninsula. IAGLR 2016 / GUELPH 2 Food webs in the Lake Superior watershed are impacted by the atmospheric deposition of mercury. Torch Lake, an inland lake connected to Lake Superior suffers from high concentrations of mercury leading to fish consumption advisories that affect members of the Keweenaw Bay Indian Community who use it as a traditional spear fishing site. This poster examines factors that influence the bioaccumulation of mercury in lake food webs; we focus here on fish community as a surrogate for food web structure. Using existing data for multiple lakes in the western Upper Peninsula, we developed an empirical relationship between lake characteristics and lake fish communities. We measured biological components of Torch Lake and compared these to the empirical model to test its ability to predict fish communities in lakes for which the model was not calibrated. This is one step towards building a model that can help predict mercury concentrations in other settings. As numerous lakes across the region have similar problems with mercury contamination, our findings will help local residents determine how much fish can be consumed safely. Keywords: Mercury, Bioaccumulation, Food chains. ALARCON, M.A. and MAIGRET, J., Taubman College of Architecture & Urban Planning, University of Michigan, Ann Arbor, MI. Visualizing the Dynamic Shorelines of the Great Lakes. The shoreline landscapes of the Great Lakes are dynamic natural systems and an important part of the culture, economy, and ecology of the coastal communities in the region. Yet our desire to inhabit the shore also yields conflict between the built environment and the physical realities of coastal dynamics. The conservation, enjoyment and development of the shoreline over time have triggered a series of planning efforts aimed to sustainably manage these resources. This talk integrates research informed by urban planning, coastal engineering, landscape architecture and law through the use of visualization techniques. The project employs computational analysis, spatial modeling and graphic visualization techniques to enhance our understanding of the complex dynamics of Great Lakes shorelines. Through the selection of specific coastal sites, the work explores different techniques of visualization to gain knowledge of a physical and ecological system that fluctuates over space and time, and question current regulatory mechanisms defining water levels and development. These digital technologies sponsor collaborative conversations between urban planners, coastal engineers, state policy makers, architects, land owners, and local public officials to find a common language for making informed shoreland management decisions.

US, Canadian, state, and international regulations will soon require ships entering the Great Lakes to treat ballast water so that virtually no live organisms will be released in discharged ballast water, thereby preventing the introduction of non-native or pathogenic species. The Automated Fluorescence Intensity Detection Device (AFIDD) was developed to differentiate live from dead organisms in ballast water by measuring enzymatic activity that metabolizes fluorescein diacetate (FDA, non-fluorescent) to fluorescein (fluorescent) in live organisms

  • (Coregonus Lavaretus (L.)) Caused by Competitor Invasion
    Speciation Reversal in European Whitefish (Coregonus lavaretus (L.)) Caused by Competitor Invasion Shripathi Bhat1*, Per-Arne Amundsen1, Rune Knudsen1, Karl Øystein Gjelland3, Svein-Erik Fevolden1, Louis Bernatchez2, Kim Præbel1 1 Department of Arctic and Marine Biology, University of Tromsø, Tromsø, Norway, 2 Institut de Biologie Inte´grative et des Syste`mes (IBIS), Universite´ Laval, Que´bec, Canada, 3 Norwegian Institute for Nature Research, Tromsø, Norway Abstract Invasion of exotic species has caused the loss of biodiversity and imparts evolutionary and ecological changes in the introduced systems. In northern Fennoscandia, European whitefish (Coregonus lavaretus (L.)) is a highly polymorphic species displaying adaptive radiations into partially reproductively isolated and thus genetically differentiated sympatric morphs utilizing the planktivorous and benthivorous food niche in many lakes. In 1993, Lake Skrukkebukta was invaded by vendace (Coregonus albula (L.)) which is a zooplanktivorous specialist. The vendace displaced the densely rakered whitefish from its preferred pelagic niche to the benthic habitat harbouring the large sparsely rakered whitefish. In this study, we investigate the potential influence of the vendace invasion on the breakdown of reproductive isolation between the two whitefish morphs. We inferred the genotypic and phenotypic differentiation between the two morphs collected at the arrival (1993) and 15 years after (2008) the vendace invasion using 16 microsatellite loci and gill raker numbers, the most distinctive adaptive phenotypic trait between them. The comparison of gill raker number distributions revealed two modes growing closer over 15 years following the invasion. Bayesian analyses of genotypes revealed that the two genetically distinct whitefish morphs that existed in 1993 had collapsed into a single population in 2008.

  • First Record of a Coregonid Fish Species, Coregenus Albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake Shared Between Turkey and Georgia
    J. Black Sea/Mediterranean Environment Vol. 25, No. 3: 325-332 (2019) SHORT COMMUNICATION First record of a coregonid fish species, Coregenus albula (Linnaeus, 1758) (Salmoniformes: Salmonidae) in Aktaş Lake shared between Turkey and Georgia Sedat V. Yerli Department of Biology, Hacettepe University, SAL, Beytepe, Ankara, TURKEY Corresponding author: [email protected] Abstract The genus Coregenus (Salmoniformes: Salmonidae) was recently considered not to be represented in Turkey. European cisco or vendace, Coregonus albula (Linnaeus, 1758) was reported for the first time for Turkey in this article with fifteen samples in Aktaş Lake, Ardahan. This species should be added to the checklist of Turkish fish fauna. Turkish name is proposed as “Akbalık” for this species. Keywords: Coregonus albula, first record, Aktaş Lake, Kartsakhi, alkaline lake, Georgia, Turkey Received: 30.10.2019, Accepted: 26.11.2019 Vendace or European cisco Coregonus albula (Linnaeus, 1758) is a native species for northern Europe. Berg (1948) reported the distribution of this species its morphological measurements in the former USSR and adjacent countries. Froese and Pauly (2019) summarized the natural distribution of vendace as Baltic basin, several lakes of upper Volga drainage; some lakes of White Sea basin and North Sea basin east of Elbe drainage; anadromous in Gulf of Finland and marine in northernmost freshened part of Gulf of Bothnia between Finland and Sweden; in Lake Inari, northern Finland; lower Rhine (now extirpated). The vendace was introduced, intentionally in some countries in Europe and United States of America. Vendace was introduced in 1959, 1982-1987 in the Irtysh River Basin and in 1960-61 in Lake Balkhash in Kazakhstan (Mitrofanov and Petr 1999).

Public domain. Available: http://eol.org/data_objects/26779416. (June 2017). 1 Native Range, and Status in the United States Native Range From Froese and Pauly (2017): “Europe: In the Baltic Sea: Swedish coast (including Bothnian Gulf, not in Gotland); in southern Baltic, extending from the Schlei to Gulf of Finland. Southeast North Sea Basin: Ems, Weser and Elbe drainages 1 and small rivers of Schleswig-Holstein and Denmark. Landlocked in several lakes in Poland, Sweden, and Russia.” Status in the United States From Neilson (2017): “Failed introduction.” “A shipment of 409 individuals from Lake Miedwie (formerly Madue Lake), Poland was stocked in Garnder Lake, Michigan in 1877 (Baird 1879; Todd 1983).” Means of Introductions in the United States From Neilson (2017): “Coregonus maraena, along with other species of Coregonus, was intentionally stocked as a food fish by the U.S. Fish Commission (Todd 1983). According to Baird (1879), 1,000 eggs of C. maraena were shipped from Poland to Michigan in 1877 and hatched in captivity at the State Hatching House in Detroit. A total of 409 of the young fish were stocked in Gardner Lake (Baird 1879; Todd 1983). Baird (1879) considered the stocking an experimental introduction of a European food fish.” Remarks From Neilson (2017): “There is much confusion regarding the identity of whitefish imported from Germany in the late 1800s by the U.S. Fish Commission, primarily due to the uncertain taxonomy and systematics of Coregonus (Kottelat and Freyhof 2007).

    HABITAT PREFERENCES AND FEEDING ECOLOGY OF BLACKFIN CISCO (COREGONUS NIGRIPINNIS) IN NORTHERN ALGONQUIN PROVINCIAL PARK A Thesis Submitted to the Committee on Graduate Studies in Partial Fulfillment of the Requirements for the Degree of Master of Science in the Faculty of Arts and Science Trent University Peterborough, Ontario, Canada © Copyright by Allan Henry Miller Bell 2017 Environmental and Life Sciences M.Sc. Graduate Program September 2017 ABSTRACT Depth Distribution and Feeding Structure Differentiation of Blackfin Cisco (Coregonus nigripinnis) In Northern Algonquin Provincial Park Allan Henry Miller Bell Blackfin Cisco (Coregonus nigripinnis), a deepwater cisco species once endemic to the Laurentian Great Lakes, was discovered in Algonquin Provincial Park in four lakes situated within a drainage outflow of glacial Lake Algonquin. Blackfin habitat preference was examined by analyzing which covariates best described their depth distribution using hurdle models in a multi-model approach. Although depth best described their distribution, the nearly isothermal hypolimnion in which Blackfin reside indicated a preference for cold-water habitat. Feeding structure differentiation separated Blackfin from other coregonines, with Blackfin possessing the most numerous (50-66) gill rakers, and, via allometric regression, the longest gill rakers and lower gill arches. Selection for feeding efficiency may be a result of Mysis diluviana affecting planktonic size structure in lakes containing Blackfin Cisco, an effect also discovered in Lake Whitefish (Coregonus clupeaformis). This thesis provides insight into the habitat preferences and feeding ecology of Blackfin and provides a basis for future study. Keywords: Blackfin Cisco, Lake Whitefish, coregonine, Mysis, habitat, feeding ecology, hurdle models, allometric regression, Algonquin Provincial Park ii ACKNOWLEDGEMENTS First and foremost I would like to thank my supervisor Dr.
