2020 Seedless Pickling Cucumber Variety Trial, Ben Phillips, Hilda Mcshane Nov 2020

2020 Seedless Pickling Cucumber Variety Trial, Ben Phillips, Hilda Mcshane

Midwest Vegetable Trial Reports

A pickling cucumber variety trial was planted at the Saginaw Valley Research and Extension Center (43.399097, -83.694497, Frankenmuth, Michigan). Bejo (BJ), Nunhems (NU), and Rijk Zwaan (RZ) seed companies donated parthenocarpic (seedless) varieties for mechanical once-over harvest.


New State Species Records And Noteworthy Re-Captures Of Michigan (Usa) Trichoptera, David Houghton Sep 2020

New State Species Records And Noteworthy Re-Captures Of Michigan (Usa) Trichoptera, David Houghton

The Great Lakes Entomologist

Ten caddisfly species are reported from Michigan for the first time, including 5 in the family Limnephilidae (Limnephilus femoralis, L. thorus, Pycnopsyche aglona, P. circularis, and P. limbata), 2 in the Polycentropodidae (Cernotina pallida and Holocentropus glacialis), 1 in the Hydroptilidae (Hydroptila fiskei), 1 in the Leptoceridae (Triaenodes perna), and 1 in the Rhyacophilidae (Rhyacophila angelita). An additional 5 unique species, including several not seen in Michigan for over 70 years, are confirmed to be extant in the state, most notably Plectrocnemia sabulosa, Michigan’s only known …


New State Record And Range Extension For Mycterus Youngi Pollock (Coleoptera: Mycteridae) – But Is It Really Rare?, Daniel K. Young Feb 2020

New State Record And Range Extension For Mycterus Youngi Pollock (Coleoptera: Mycteridae) – But Is It Really Rare?, Daniel K. Young

The Great Lakes Entomologist

Mycterus youngi was described from Wisconsin and “L.S” (presumed to indicate along Lake Superior). All but one of the specimens in the type series were collected between 1947 and 1949. Herein, three females of M. youngi are reported from Michigan, between 1910 and 1940. A discussion of possible implications of the few, and largely old collection dates is provided.

Detection And Classification Of Eurasian Watermilfoil With Multispectral Drone-Enabled Sensing, Colin Brooks Jan 2020

Detection And Classification Of Eurasian Watermilfoil With Multispectral Drone-Enabled Sensing, Colin Brooks

Dissertations, Master's Theses and Master's Reports

Littoral zones support growth of submerged aquatic vegetation, creating productive areas that provide food and habitat for fish, amphibians, macroinvertebrates, and other parts of the food web. Understanding macrophyte dynamics requires the identification of submerged aquatic vegetation (SAV) taxa, which can be possible if taxa of interest are spectrally distinct with data collected at appropriate scales. Eurasian watermilfoil, Myriophyllum spicatum or EWM, is a non-native SAV species that forms thick, often monotypic beds that reduce benthic species richness, restrict recreation, reduce property values, clog water intakes, and lower dissolved oxygen concentrations. Remote sensing of SAV species has to address the …


Effects Of Wild Pig Disturbance On Forest Vegetation And Soils, Steven M. Gray, Gary J. Roloff, Daniel B. Kramer, Dwayne R. Etter, Kurt C. Vercauteren, Robert A. Montgomery Jan 2020

Effects Of Wild Pig Disturbance On Forest Vegetation And Soils, Steven M. Gray, Gary J. Roloff, Daniel B. Kramer, Dwayne R. Etter, Kurt C. Vercauteren, Robert A. Montgomery

USDA Wildlife Services: Staff Publications

In North America, wild pigs (Sus scrofa; feral pigs, feral swine, wild boars) are a widespread exotic species capable of creating large‐scale biotic and abiotic landscape perturbations. Quantification of wild pig environmental effects has been particularly problematic in northern climates, where they occur only recently as localized populations at low densities. Between 2016 and 2017, we assessed short‐term (within ~2 yrs of disturbance) effects of a low‐density wild pig population on forest features in the central Lower Peninsula of Michigan, USA. We identified 16 8‐ha sites using global positioning system locations from 7 radio‐collared wild pigs for sampling.Within each …
