Importance of nonindigenous harpacticoids (Crustacea: Copepoda) decrease with depth in Lake Ontario Importance of nonindigenous harpacticoids (Crustacea: Copepoda) decrease with depth in Lake Ontario
Harpacticoid copepods can be a substantial component of the meiobenthic community in lakes and serve an ecological role as detritivores. Here we present the first species-level lake-wide quantitative assessment of the harpacticoid assemblage of Lake Ontario with emphasis on the status of nonindigenous species. Additionally, we provide COI-5P sequences of harpacticoid taxa through Barcode...

First record of the non-indigenous parasitic copepod Neoergasilus japonicus (Harada, 1950) in the Lake Ontario Watershed: Oneida Lake, New York First record of the non-indigenous parasitic copepod Neoergasilus japonicus (Harada, 1950) in the Lake Ontario Watershed: Oneida Lake, New York
Four specimens of the Asiatic parasitic copepod Neoergasilus japonicus (Harada, 1930) were collected from Oneida Lake, New York in September 2018; one specimen was from a white sucker Catostomus commersonii, another from a green sunfish Lepomis cyanellus, and two from a bluegill Lepomis macrochirus. The four adult female specimens were found attached to the base of the gills of their...

A multi-species synthesis of physiological mechanisms in drought-induced tree mortality A multi-species synthesis of physiological mechanisms in drought-induced tree mortality
Widespread tree mortality associated with drought has been observed on all forested continents and global change is expected to exacerbate vegetation vulnerability. Forest mortality has implications for future biosphere–atmosphere interactions of carbon, water and energy balance, and is poorly represented in dynamic vegetation models. Reducing uncertainty requires improved mortality...

Eurytemora carolleeae in the Laurentian Great Lakes revealed by phylogenetic and morphological analysis Eurytemora carolleeae in the Laurentian Great Lakes revealed by phylogenetic and morphological analysis
In the Laurentian Great Lakes, specimens of Eurytemora have been reported asEurytemora affinis since its invasion in the late 1950s. During an intensive collection of aquatic invertebrates for morphological and molecular identification in Western Lake Erie in 2012-2013, several specimens of Eurytemora were collected. Analysis of these specimens identified them as the recently described...

Observations of cocooned Hydrobaenus (Diptera: Chironomidae) larvae in Lake Michigan Observations of cocooned Hydrobaenus (Diptera: Chironomidae) larvae in Lake Michigan
Larvae of the family Chironomidae have developed a variety of ways to tolerate environmental stress, including the formation of cocoons, which allows larvae to avoid unfavorable temperature conditions, drought, or competition with other chironomids. Summer cocoon formation by younger instars of the genus Hydrobaenus Fries allows persistence through increased temperatures and/or...

Morphological identification and COI barcodes of adult flies help determine species identities of chironomid larvae (Diptera, Chironomidae) Morphological identification and COI barcodes of adult flies help determine species identities of chironomid larvae (Diptera, Chironomidae)
Establishing reliable methods for the identification of benthic chironomid communities is important due to their significant contribution to biomass, ecology and the aquatic food web. Immature larval specimens are more difficult to identify to species level by traditional morphological methods than their fully developed adult counterparts, and few keys are available to identify the...
