Therefore, changes in the structure of the zooplankton community affect how energy moves through aquatic ecosystems. Changes in the zooplankton community structure are typically documented through detailed community analysis, which can be difficult to interpret and communicate to non-experts. Alternatively, a few key summary indicators of community structure may better disseminate this information to a broader audience. In this study we analyzed zooplankton data from 1997 to 2019 from the US Environmental Protection Agency’s Great Lakes National Program Office to select indicators that summarized changes in the zooplankton community. Two indicators (percent of calanoids by biomass and areal density of herbivorous cladocerans) detected known changes in lakes Huron, Michigan, and Ontario, correlated with the crustacean zooplankton areal biomass above (herbivorous cladocerans) or in the hypolimnion (percent calanoids), and were related to the lake or basin-wide Carlson’s Trophic State Index based on chlorophyll (TSI_chl) (percent calanoids by biomass). Our findings suggest that employing one or both selected indicators in addition to TSI_chl and total crustacean zooplankton areal biomass, an already reported indicator in the Great Lakes that captures overall food availability for fish, would provide additional key information about zooplankton community structure in simple metrics that could be effectively communicated to stakeholders.</div></div>","PeriodicalId":54818,"journal":{"name":"Journal of Great Lakes Research","volume":"50 5","pages":"Article 102417"},"PeriodicalIF":2.4,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142316240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cisco historically supported large commercial fisheries in the Great Lakes during the late 1800s and early 1900s, but many populations declined and never recovered. Restoration efforts focusing on re-establishing cisco in the Great Lakes are underway, but increasing water temperatures may hinder these efforts. Therefore, we examined aerobic scope and thermal tolerance of allopatric cisco populations from different latitudes and habitats to determine if a southern latitude population (Crooked Lake, Indiana, USA) near the southern edge of cisco distribution was better adapted to withstand warmer water temperatures than a northern latitude population (Les Cheneaux Islands, Michigan, USA; Lake Huron). As expected, both stocks demonstrated increases in metabolic rates and absolute aerobic scope with increased temperature. Northern cisco had significantly lower aerobic scope compared to southern cisco at both treatment temperatures of 10 and 13 °C. Both cisco stocks had high thermal tolerances when challenged by temperatures increased to 20 and 23 °C but low tolerances at 26 °C. Cisco thermal tolerances increased with acclimation temperature, but we did not detect a difference in thermal tolerances between northern and southern cisco. Although southern cisco had higher capacity for aerobic metabolism, both stock sources had high thermal tolerances at the upper end of their thermal limits. Therefore, either population would be likely suitable for reintroduction into Great Lakes habitats, even with expected warming in the future.</div></div>","PeriodicalId":54818,"journal":{"name":"Journal of Great Lakes Research","volume":"50 5","pages":"Article 102415"},"PeriodicalIF":2.4,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142316133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Like Lake Michigan, the estuary was thermally stratified July to October, and historically dredged channels with water depths greater than 6 m allowed for the free movement of cold lake water into the estuary. However, temperatures in the estuary fluctuated rapidly both spatially and temporally, reflecting lake temperature fluctuations driven by changing meteorological conditions. Lake-driven upwelling and downwelling events influenced water temperature more than tributary contributions. Periodic upwelling and downwelling events caused temperature changes by up to 15 °C in less than 24 h. Nearshore upwelling events occasionally allowed cold, hypolimnetic lake water to reach tributary portions of the estuary beyond dredged areas, while downwelling events disrupted thermal stratification and caused the deep, dredged portions of the estuary to exceed 20 °C. Thermal impacts from these events were especially noticeable in transition zones between dredged and not dredged channels less than 2 m deep. The warming effects from downwelling persisted longer inside the estuary – up to two weeks – than cooling effects from upwelling, which typically lasted a few days. The predominantly lake-driven, rapid summer water temperature fluctuations observed in the Milwaukee Estuary serve as an important consideration in habitat restoration activities happening in Great Lakes estuaries.</div></div>","PeriodicalId":54818,"journal":{"name":"Journal of Great Lakes Research","volume":"50 5","pages":"Article 102416"},"PeriodicalIF":2.4,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0380133024001758/pdfft?md5=555a5d9dc1be2d20211fa046cec9b08c&pid=1-s2.0-S0380133024001758-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142316238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major findings are that: (1) The sandy lake bottom is distinct in bathymetric character from other compositions/textures, including bedrock, gravel-lag, and muddy sediments; (2) the Chicago North Side is sandier than the Chicago South Side; (3) sand thickness is greatest beneath urban pocket beaches and decreases sharply at the transition from engineered embayment to open lake environment; (4) sand thickness beyond semi-confinement is generally < 1 m, with the toe of the littoral sand wedge generally in > 5 m water depth; and (5) while the Chicago North Side littoral zone is continuously sandy alongshore, with few obstructions impacting unit continuity, that of the South Side is characterized by littoral fragmentation given exposure of bedrock highs.

The geomorphological attributes of the two sites presented challenges in successfully reproducing the observed streamflow with a conceptual model, like SWAT. After adjusting the model inputs and revising the boundary conditions, SWAT performance for the Napanee River model was found to be “very good” within both calibration (Nash-Sutcliffe efficiency, NSE, =0.83 and NSE = 0.87 for the daily and monthly streamflow rates, respectively) and validation (NSE = 0.87 and NSE = 0.91) domains. In contrast, despite the small size of Wilton Creek (∼233 km²) and the lack of permanent or human-regulated dams, the observed streamflow patterns displayed considerably delayed response to extreme precipitation events which posed challenges in achieving satisfactory model performance. Field evidence suggests that model residual variability is driven by excessive surface storage of water, the presence of beaver dams and narrowing of the stream channels under the bridges, which could potentially delay the flow of water for many days.

To help understand the cumulative impacts of local and regional factors on the trophic ecology of this large freshwater ecosystem, we used the paleolimnological approach to reconstruct changes over the past ∼ 200 years of primary production (subfossil pigments, diatom microfossils), secondary production (cladoceran zooplankton microfossils) and geochemistry (carbon and nitrogen isotopes, elemental analyses, % organic matter). Between ca. 1950 and the 2000’s changes in the sedimentary proxies are consistent with an enhanced influx of nutrients and dissolved organic carbon likely due to the cumulative landscape disturbances and an increase in precipitation. These changes include shifts in diatom composition ca. 1950 to higher abundances and taxa indicative of decreased light penetration and nutrient enrichment. Increases in δ¹⁵N (∼ +1‰) and cladoceran concentrations, concurrent with increasing sockeye salmon escapement post ca. 1975, is indicative of a higher pelagic fish production that occurs concurrently with both fisheries enhancements and sustained higher precipitation. The largest and most abrupt change in algal pigments occurred post ca. 2000, characterized by increases in motile and buoyant algae (i.e., chrysophytes, cryptophytes, colonial cyanobacteria), a time of increasing regional air temperatures, reduced spring and autumn winds, and resultant changes in patterns of lake mixing.</div></div>","PeriodicalId":54818,"journal":{"name":"Journal of Great Lakes Research","volume":"50 5","pages":"Article 102395"},"PeriodicalIF":2.4,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0380133024001539/pdfft?md5=73ca425f4899d5450ba008e4aa54c32c&pid=1-s2.0-S0380133024001539-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142316131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
