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 ...
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 ...
Genetic variation in the phenolic concentration and inducibility in explanding leaves of Populus tremuloides.
(2002)
The co-existence of plants and herbivores has resulted in various chemical and mechanical adaptations in plants. Phenolics form one of the largest groups of defensive chemical compunds and are ubiquitous among all plants. ...
Lancaster Lake Survey, Cheboygan County, Michigan.
(2002)
The survey of Lancaster Lake concluded that it is between a mesotrophic and eutrophic lake. By using the chemical and biotic data collected on July 6, 2002, the lake's watershed characteristics and tophic status were determined.
Plastic, wood or concrete, which is the best river bank retaining wall material?
(2002)
Erosion is a problem on many streams and rivers. Should land owners decide to protect the stream bank on their property, the construction causes serious disturbance to the aquatic community. Algae periphyton has been used ...
Distribution of soil types and tree communities as a function of glacial landroms in northern lower Michigan.
(2002)
The relationship between glacial features, tree communities and soil characteristics was studied at a moraine and two outwash plains on the UMBS property. There was a significant difference found in DBH, nitrogen, juvenile ...
Substrate preference for sand and cobble of Lymnaea stagnalis in an artificial stream.
(2002)
Study has been done on preference of substrate for Lymnaea Stagnalis snails from Douglas Lake located in Pellston, MI. The site of the study was the section of the Maple River, adjacent to the Rivers and Streams Research ...
The effect of acid deposition on American beech growth.
(2002)
Human induced acid precipitation has been shown to cause large negative effects on sensitive ecosystems in areas that have a direct association with a large-scale producer of pollution. However, the effects of acid deposition ...
The impact of natural selection on the feeding preference of birds in northern Michigan.
(2002)
Natural selection may influence feeding preference by selecting for levels of nutrients that may be beneficial to survival and reproduction. We hypothesized that this force may be acting on bird feeding preference by ...
Spider predation as a selective pressure on midge body size.
(2002)
The adaptationist paradigm suggests that organisms today are primarily a result of natural selection. However, fixed and neutral traits, as well as genetic drift, often undermine the assumed pervasiveness of natural ...
