Observations on the habitat of Pogonia ophioglossoides (Orchidaceae) in Northern Michigan.
(1997)
In conclusion, observation of Pogonia ophioglossoides, the rose pogonia or snake's mouth orchid, appears to indicate that it is a moisture-loving, calciphilic, minerotrophic fen species which grows on the quaking mat, poor ...
Effects of elevated CO2 and paternal family on stomatal index and size in wild radish (Raphanus raphanistrum).
(1993)
Rising atmospheric carbon dioxide may become a stronger selection force in a future environment if certain genotypes exhibit differential responses to elevated CO2. Heritable variation must be present within natural ...
A comparison of soil arthropod communities in successional forest plots.
(1995)
Many abiotic factors may influence the diversity and abundance of soil arthropods in forest plots. This study tried to determine how diversity and abundance of arthropods changed as forest recover and regrow, and which, ...
A comparison of the maneuverability of bluegill and sunfish to that of minnows.
(1993)
The purpose of conducting this experiment is to determine which has more maneuverability--bluegills and sunfish or minnows? It will be interesting to determine the answer to this question as each of these two types of fish ...
Color preference in seed choice of birds in the Douglas Lake Region.
(1996)
This study asked whether birds of the UMBS region exhibit a preference among seeds of different colors. Specifically, we expected that birds would prefer brown seeds, which are associated with abundant and/or nutritious ...
Effects of pH, nutrient availability, and mycorrhizal association on distribution of Kalmia polifolia in Mud Lake bog.
(1995)
The distribution of organisms is often affected by the presence of abiotic factors in the environment. As a result, many organisms have developed mutualistic relationships with other organisms in order to increase chances ...
Aquatic insect diversity as a function of nutrient levels in a northern Michigan stream.
(1991)
Species diversity in natural systems generally correlate with environmental heterogeneity. In this experiment, I examined insect colonizations of artificial substrates (ribbons) along five different sites of the West ...
Sturgeon River community study.
(1993)
The purpose of our study is to conduct a detailed examination of the Sturgeon River fish community. This entails describing the physical habitat of the river and determining what fish and other fauna are present. We will ...
