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 ...
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 ...
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 ...
The effect of acid rain on the annual growth of Pinus strobus and Acer rubrum.
(2001)
Acid deposition, a side effect of human advances in industrial and agricultural technology, is now known to affect multiple components of ecosystem health on both a local and multiregional scale. Our study investigated the ...
Caddisfly (Trichoptera) larvae distribution in the Maple River.
(2002)
Caddisflies of the three superfamilies, Spicipalpia, Integripalpia, and Annulipalpia, produce cases during an aquatic larval stage to aid in their growth and development. The distribution of these cases in rivers and streams ...
Prevalence of Haemosporidians in birds of Northern Michigan.
(2006)
In this study, the prevalence of Haemosporidians in birds of Northern Michigan was investigated with an emphasis on the parasite Plasmodium in passerine birds. Birds caught and banded by mist-netters were sampled for blood ...
The behavior of ozone flux in the plants at PROPHET Tower in UMBS.
(2003)
Ozone is the primary precursor of OH. OH is a very strong oxidant and will immediately oxidize of almost organic molecules. Tropospheric ozone has been demonstrated to cause damage to forest trees. Volatile organic compounds ...
The relationship between Phalaris arundinacea and Glyceria grandis and their epiphyte communities in the Maple River.
(2002)
The relationship between epiphytes and their aquatic hosts has scarcely been studied for freshwater ecosystems. The epiphytes gain substrate on which to live from the plants but how do they affect the plants? Understanding ...
Diatoms as bioindicators: does the stream lab have an effect downstream?
(2003)
Diatom communities developed on tiles in four different locations on the Maple River were subjected to short term growth in order to test the hypothesis that the Michigan Biological Stream Lab will have an effect at the ...
