Substrate preferences of Campeloma decisum and Elimia livescens: influence of species interaction and substrate tenacity.
(2001)
This investigation sought to examine if substrate choice among the freshwater operculate snails Campeloma decisum and Elimia livescens in Douglas Lake, Cheboygan County, Michigan could be explained by species interaction ...
Ecological analysis of beetle (Coleoptera) density and diversity as bioindicators of accelerated succession in the UMBS FASET experiment.
(2009)
This study assessed beetle (order: Coleoptera) density and diversity as bioindicators for changes in northern Michigan forests undergoing succession. At UMBS, forests are succeeding from an aspen and birch dominated canopy ...
The effects of various environmental factors on the success of tristylous Lythrum salicaria.
(2001)
Invasive species can influence a community, causing a decline or even extinction of native species. Lythrum salicaria, or purple loosestrife, is an exotic, tristylous plant that spreads over disturbed wetland areas in ...
Investigation of ozone stomatal flux in a northern mixed hardwood forest during the 1999 to 2004 growing seasons
(2007)
Hourly ozone stomatal fluxes (Fs_O3) were calculated for the University of Michigan’s Biological Station (UMBS) forest in northern Michigan from June 15 to September 15 for each year from 1999 to 2004 based on a set of ...
Effects of Dreissena polymorpha and Pyganodon grandis on algal density
(2018)
Invasive species often compete with native species for various resources. This study investigated how an invasive species in Douglas Lake, the zebra mussel, and a native species, freshwater clams, would impact algal ...
Nitrogen flow and distribution in a northern Michigan dune system
(2008)
While the study of nutrient flow from terrestrial habitats to aquatic habitats is well known, little is known of the nutrient flow from aquatic to terrestrial habitats. The study of nitrogen flow from water to land in a ...
Impairment of feeding behavior of the spottail shiner (Notropis hudsonius) by metacercariae of the digenetic trematode Diplostomum flexicaudum.
(2004)
The spottail shiner (Notropis hudsonius) was infected in the laboratory with cercariae of the eye fluke Diplostomum flexicaudum to determine if infection by the parasite impaired feeding behavior of the fish. The mean and ...

A study on the pollination of the sarsaparilla flower.
(2013)
In this study, we examined the pollination rate of Aralia nudicaulis, commonly known as
the sarsaparilla flower. Sarsaparilla is an angiosperm without specialized pollinators. We
observed the plants at three different ...
