A Study Of The “Iron Ridge” Mine: An Excerpt From When Iron Was King In Dodge County, Wisconsin, George G. Frederick
A Study Of The “Iron Ridge” Mine: An Excerpt From When Iron Was King In Dodge County, Wisconsin, George G. Frederick
Field Station Bulletins
Mining began at the Iron Ridge Mine (now commonly called Neda Mine) in 1849. The ore is relatively concentrated (nearly 55% iron by weight) and was easily mined initially because some deposits were surficial and of a loosely-cemented granular structure. In the 1850's Byron H. Kilbourn (twice mayor of Milwaukee) purchased most of the land surrounding a competitor's open pit mine, and in 1864 his own Swedes Iron Co. began underground mining. The period from 1850 to 1890 was a period of intense railroad construction in the United States, so there was a high demand for iron from this mine. …
Seasonal Changes And Overwintering Of Endoparasites In The Bat (Myotis Lucifugus) In A Southeastern Wisconsin Hibernaculum, James R. Coggins
Seasonal Changes And Overwintering Of Endoparasites In The Bat (Myotis Lucifugus) In A Southeastern Wisconsin Hibernaculum, James R. Coggins
Field Station Bulletins
Eight digenetic trematode species (Phylum Platyhelminthes, Subclass Digena), one cestode species (Phylum Platyhelminthes, Class Cestoidea) and three nematode species (Phylum Nematoda) were recovered from the little brown bat, Myotis lucifugus, at the Neda Mine hibernaculum in southeastern Wisconsin. Bats displayed a rich and diverse helminth fauna throughout the year. Statistically significant seasonal variation was observed for two digenetic trematodes. Mean intensities and prevalence of parasites were highest in autumn and spring and lowest in summer. Highest species diversity occurred in autumn. Greater intensity and prevalence in autumn and spring were correlated with bat swarming and emergence patterns, behavioral phenomena which …
Seasonal Activity Patterns In The Bat Community At Neda Mine, Charles Rupprecht
Seasonal Activity Patterns In The Bat Community At Neda Mine, Charles Rupprecht
Field Station Bulletins
Even though bats represent a relatively abundant, biologically fascinating and highly beneficial component of Wisconsin's wildlife, they remain poorly studied and greatly misunderstood. Accounts of the seasonal adaptive strategies of most bats are inadequate or fragmentary (Barbour and Davis 1969). Rarely have researchers investigated more than one species at a single time and place. The aim of this study was to make simultaneous comparisons by sex and species of the various adaptive strategies employed by members of the Neda Mine bat community on an annual basis.
