Bald Eagles Wintering Along The Des Moines River, Iowa, Neil Sabine Jan 1996

Bald Eagles Wintering Along The Des Moines River, Iowa, Neil Sabine

Journal of the Iowa Academy of Science: JIAS

Distribution, habitat use, and foraging behavior of Bald Eagles (Haliaeetus leucocephalus) wintering in southeast Iowa were studied in January - March 1990 and November 1990 - March 1991. Eagles were seen from November through March with the highest numbers in January and February. Adults had shorter winter residence times than immatures and they appeared to be less active during the day. Eagles concentrated their foraging efforts along certain river segments where they fed exclusively on fish. Timber harvesting along the river reduced eagle use and is considered to be the most serious threat to sustaining eagle use of the area. …


Life History And Status Classifications Of Birds Breeding In Iowa, Louis B. Best, Kathryn E. Freemark, Barbara S. Steiner, Timothy M. Bergin Jan 1996

Life History And Status Classifications Of Birds Breeding In Iowa, Louis B. Best, Kathryn E. Freemark, Barbara S. Steiner, Timothy M. Bergin

Journal of the Iowa Academy of Science: JIAS

Life history and status classifications were compiled for 145 bird species that breed in Iowa. Species were classified by food type and substrate, nest substrate, susceptibility to cowbird parasitism, migratory status, predominant habitat use and habitat-use specialization, body mass (an index of home range/territory size), area sensitivity, population trend and vulnerability, and beneficial/harmful aspects in relation to agriculture. Such information may be used to make interspecific comparisons, evaluate interrelationships among life history and status characteristics, and provide insights into the interpretation of previous research. This synthesis also can aid those responsible for making conservation and management decisions about Iowa's avifauna.

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther Jan 1996

The Natural History Of Aconitum Noveboracense Gray (Northern Monkshood), A Federally Threatened Species, Margaret A. Kuchenreuther

Journal of the Iowa Academy of Science: JIAS

Aconitum noveboracense Gray (Ranunculaceae), commonly known as northern monkshood, is a federally threatened herbaceous perennial that occurs in disjunct populations in Iowa, Wisconsin, Ohio and New York. It appears to be a glacial relict, existing today only in unique areas with cool, moist microenvironments, such as algific talus slopes. Field studies reveal that A. noveboracense has a complex life history. Perennation of individual plants occurs through the annual production of daughter tubers. Vegetative reproduction is commonly observed, and can occur by means of aerial and subterranean bulbils, as well as by development of adventitious root buds. Populations also reproduce sexually …

Gender Patterns In Science Course Enrollment And Course Drop Patterns In An Iowa Senior High School, Sandra L. Stephen, Elizabeth D. Riesz

Journal of the Iowa Academy of Science: JIAS

In order to ascertain whether local patterns corresponded to the national trends, which show fewer female and minority students enrolling in and completing high school physical science courses, the Cedar Rapids Community School District studied the course enrollment and drop patterns of seniors in one of the District high schools. Male students predominated in physics and AP Chemistry, and the proportion of males in AP Physics was significantly greater than the proportion of females. The proportion of females in chemistry was significantly greater than their proportion in the senior class. Course dropping patterns revealed a statistically significant relationship between gender …


Survey Of Hematozoa And Intestinal Helminths Infecting Green-Winged Teal In Guthrie County, Iowa, Rick Klann, Bryan Hellyer Jan 1995

Survey Of Hematozoa And Intestinal Helminths Infecting Green-Winged Teal In Guthrie County, Iowa, Rick Klann, Bryan Hellyer

Journal of the Iowa Academy of Science: JIAS

Five helminths and one sporozoan were recovered from 21 hunter-killed green-winged teal collected from Lakin Slough in Guthrie County, Iowa during October and November of 1991. The sporozoan, Leucocytozoon simondi, was identified in blood smears from all 21 teal. The helminths recovered from the alimentary tract included three trematodes, Cotylurus flabelliformis, Echinostoma trivolvis and Zygocotyle lunata; a hymenolepid tapeworm; and one acanthocephalan, Corynosoma constrictum. The ecological factors associated with infection by these parasites are discussed.

Paleokarst And Associated Mineralization At The Linwood Mine, Scott County Iowa, Paul L. Garvin Jan 1995

Paleokarst And Associated Mineralization At The Linwood Mine, Scott County Iowa, Paul L. Garvin

Journal of the Iowa Academy of Science: JIAS

Operations at the Linwood Mine in Scott County, Iowa, have exposed, on two working levels, extensive pre-Pennsylvanian paleokarst and associated sediment fillings and mineralization in Middle Devonian limestones. Cavities in Davenport-Spring Grove host rocks range up to 270 meters in length and are virtually all filled with fluviatile sediment. Cavities in Cedar Rapids host rocks, on average, are smaller and some are unfilled. Limestone dissolution was controlled by high-angle fractures with a wide variety of orientations and by bedding plane and stylolitic partings. Dissolutional features on both levels of the mine provide evidence for phreatic and vadose processes. Most of …
