Influences of seasonality and habitat quality on Great Lakes coastal wetland fish community composition and diets Influences of seasonality and habitat quality on Great Lakes coastal wetland fish community composition and diets
Great Lakes coastal wetlands (GLCW) have been severely degraded by anthropogenic activity over the last several decades despite their critical role in fish production. Many Great Lakes fish species use coastal wetland habitats for spawning, feeding, shelter, and nurseries throughout the year. The goal of our study was to compare GLCW fish community composition in the spring, summer, and...

Variation of cisco egg size among Laurentian Great Lakes populations Variation of cisco egg size among Laurentian Great Lakes populations
Many fish species display inter-population and inter-individual egg size variation. Intra-specific differences in egg size seemingly reflect both energetic experiences of individual spawning fish and long-term population responses to differing ecosystems. Optimal egg size theory implies that selection influences a population’s mean egg size in response to its early-life environment...

Fungal endophyte effects on invasive Phragmites australis performance in field and growth chamber environments Fungal endophyte effects on invasive Phragmites australis performance in field and growth chamber environments
Manipulating plant microbiomes may provide control of invasive species. Invasive Phragmites australis has spread rapidly in North American wetlands, causing significant declines in native biodiversity. To test microbiome effects on host growth, we inoculated four common fungal endophytes into replicated Phragmites genotypes and monitored their growth in field and growth chamber...

Extent of sedge-grass meadow in a Lake Michigan drowned river mouth wetland dictated by topography and lake level Extent of sedge-grass meadow in a Lake Michigan drowned river mouth wetland dictated by topography and lake level
Water-level fluctuations are critical in maintaining diversity of plant communities in Great Lakes wetlands. Sedge-grass meadows are especially sensitive to such fluctuations. We conducted vegetation sampling in a sedge-grass dominated Lake Michigan drowned river mouth wetland in 1995, 2002, and 2010 following high lake levels in 1986 and 1997. We also conducted photointerpretation...

Soft pressure sensor for underwater sea lamprey detection Soft pressure sensor for underwater sea lamprey detection
In this paper, an economical and effective soft pressure sensor for underwater sea lamprey detection is proposed, which consists of an array of piezoresistive elements between two layers of perpendicular copper tape electrodes, forming a passive resistor network. With multiplexers, the apparent resistance corresponding to each pixel of the sensing matrix can be measured directly, where...

Phoretic sharksuckers (Echeneis naucrates) associated with an elasmobranch host occupy higher relative trophic positions Phoretic sharksuckers (Echeneis naucrates) associated with an elasmobranch host occupy higher relative trophic positions
The relationship between phoretic diskfishes and their hosts is a classic example of marine symbiosis, yet surprisingly few studies have quantified this trophic relationship. We investigated the hypothesis that by consuming host parasites and prey scraps phoretic diskfishes (Echeneidae) feed at a higher relative trophic position than free-living individuals through expanded foraging...

Results of the collaborative Lake Ontario bloater restoration stocking and assessment, 2012–2020 Results of the collaborative Lake Ontario bloater restoration stocking and assessment, 2012–2020
Bloater, Coregonus hoyi, are deepwater planktivores native to the Laurentian Great Lakes and Lake Nipigon. Interpretations of commercial fishery time series suggest they were common in Lake Ontario through the early 1900s but by the 1950s were no longer captured by commercial fishers. Annual bottom trawl surveys that began in 1978 and sampled extensively across putative bloater habitat...

Balancing prey availability and predator consumption: A multispecies stock assessment for Lake Ontario Balancing prey availability and predator consumption: A multispecies stock assessment for Lake Ontario
Trophic interactions are drivers of ecosystem change and stability, yet are often excluded from fishery assessment models, despite their potential capacity to improve estimates of species dynamics and future fishery sustainability. In Lake Ontario, recreational salmonine fisheries, including Chinook salmon (Oncorhynchus tshawytscha) and lake trout (Salvelinus namaycush), depend on a...

Local diversity in phenological responses of migratory lake sturgeon to warm winters Local diversity in phenological responses of migratory lake sturgeon to warm winters
Rich intraspecific diversity in traits that shape responses to environmental conditions implies that effects of climate change will differ within species or even populations. Nevertheless, few studies investigate how different groups within species respond to climatic fluctuations, and most risk assessments rely upon species-wide generalizations. We studied effects of among-year...

Bioaccumulation of perfluoroalkyl substances in a Lake Ontario food web Bioaccumulation of perfluoroalkyl substances in a Lake Ontario food web
Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals detected throughout the environment. To better understand the distribution of PFAS in an aquatic system (the Laurentian Great Lakes), stable isotope enrichment (δ13C and δ15N), fatty acid (FA) profiles, and PFAS were measured in various species from the Lake Ontario (LO) aquatic food web. Sampled organisms...
