Natural History In Iowa: The Early Phases, David C. Glenn-Lewin, Thomas R. Rosburg

Journal of the Iowa Academy of Science: JIAS

Natural history in Iowa prior to the 20th Century can be conveniently arranged into 4 phases: Native American, before the Louisiana Purchase, between the Louisiana Purchase and about 1850, and after 1850. Native American natural history was extensive and had a distinctly spiritual character. Natural history was a component of European exploration up to the time of the Louisiana Purchase, but was not treated as a separate endeavor; the evidence from this period comes from the journals and diaries of early exploreres, fur traders and the like. Between the Louisiana Purchase and about 1850, natural history changed from its status …

A Guide To The Natural History Of The Cedarburg Bog: Part Ii, James A. Reinartz Apr 1986

A Guide To The Natural History Of The Cedarburg Bog: Part Ii, James A. Reinartz

Field Station Bulletins

The boardwalk that extends to the center of the Cedarburg Bog is the UWM Field Station's most heavily used teaching facility. Research is also conducted in the Bog, which holds an understandable fascination for researchers and students of natural history because of its size, complexity, diversity and geographical isolation from similar communities. Because of the increasing research and teaching use of the Bog, it has become essential that some of what is known about the natural history of the Bog be assembled and summarized in an easily accessible introduction and guide. The guide contains too much material to fit into …

The Ethology Of The Wasp, Pseudomasaris Edwardsii (Cresson), And A Description Of Its Immature Forms (Hymenoptera: Vespoidea, Masaridae), Phillip F. Torchio Jan 1970

The Ethology Of The Wasp, Pseudomasaris Edwardsii (Cresson), And A Description Of Its Immature Forms (Hymenoptera: Vespoidea, Masaridae), Phillip F. Torchio

All PIRU Publications

In a greenhouse, each nest of Pseudomasaris edwardsii (Cresson) was constructed of nectar-moistened soil, was solitary and was placed in open but concealed niches attached to a variety of substrates. The wasp anchored her egg by its posterior tip to the bottom of the cell, deposited a jellylike cylindrical provision composed of Phacelia pollen and nectar and constructed a cell cap. Soil carried to the nest was attached to the post genal surfaces of the female's head, and the pollen and nectar were transported in her honey stomach. Cells were clustered and attached to each other and to the substrate …
