Annual Report Of The Iowa Academy Of Science, 1993-94, Paul E. Rider

Journal of the Iowa Academy of Science: JIAS

Since 1976, annual reports have served as a continuing record of the activities of the Iowa Academy of Science and an archive for its history. These augment the 100 year IAS history written in the centennial year of 1975.

This report covers the period from July 1, 1993 to June 30, 1994. It is based on the official records of the Academy (committee reports, Board minutes, correspondence) as well as the recollections, impressions and thoughts of the author.

Charles Rueben Keyes And The History Of Iowa Archaeology, William Green

Journal of the Iowa Academy of Science: JIAS

Charles Reuben Keyes (1871-1951) achieved recognition during his lifetime as the "founding father" of Iowa archaeology, and later assessments confirmed and reemphasized Keyes' stature as Iowa's pioneer archaeologist. The collections and documents Keyes compiled, his interpretive publications, and the records of field work he coordinated have proven more valuable to Midwest and Plains archaeology every year. This article emphasizes Keyes' involvement in the development of professionalism in American archaeology and Iowa’s position in the growth of the discipline from 1920 to 1950. Keyes' contacts with the principal archaeologists of his era ensured Iowa’s involvement in the development of survey methods …

Ground Water Quality And Management In Minnesota, Jeanette H. Leete

Journal of the Minnesota Academy of Science

Minnesota is known for its abundant surface water - lakes, rivers, and streams - and much emphasis is placed on managing these priceless resources, yet it is ground water that supplies drinking water to about 75 percent of the state's population, and ground water that agriculture depends on for 88 percent of irrigation water. While ground water quality can be and is impacted by activities at the land surface, the greatest proportion of Minnesota's ground water is still suitable for most uses.

Over 175 units and several levels of government are involved in water resource protection and planning. Choices are …

Nesting Of Raptors Uncommon In Iowa: Summary And New Records, Dean M. Roosa, Jon Stravers

Journal of the Iowa Academy of Science: JIAS

The nesting status of the Turkey Vulture, Bald Eagle, Northern Harrier, Sharp-shinned Hawk, Cooper's Hawk, Red-shouldered Hawk, Broad-winged Hawk, Swainson's Hawk, Peregrine Falcon, Common Barn-Owl, Burrowing Owl, Long-eared Owl and Short-eared Owl is reviewed and previously unpublished records added. Also the potential for the Northern Saw-whet Owl and Osprey to nest in Iowa is discussed. Although several species are on the brink of extirpation as part of Iowa's nesting avifauna, the Bald Eagle has returned as a regular nester. Over 100 previously unpublished nesting reports and some management recommendations are included.

Genetic Analysis Of Evolutionary Processes, Horst Wilkens

International Journal of Speleology

Epigean and cave populations of A. fasciatus (Characidae, Pisces) differ in a series of morphological physiological, and ethological features. The interfertility of these populations made possible a genetic analysis of organs characteristic of interspecific divergence. The study of the regressive organs “eye” and “melanophore system” on the one hand and that of the constructively improved “gustatory equipment" and "feeding behaviour” on the other yielded identical principles of genetic manifestation: (1) All features have a polygenic basis with an at least di- to hexahybrid inheritance. (2) All polygenes have the same amount of expressivity. (3) After recombination of a minimum number …

A Contribution To The Knowledge Of The Invertebrate Cave Faunas Of Venezuela: Invertebrate Faunas Of Tropical American Caves, Part 4, Stewart B. Peck

International Journal of Speleology

The invertebrate faunas of four caves in northern Venezuela were studied. Three were dry and one was a wet cave; but guano provided the base of the food chain in all four caves. The faunas in each were strikingly different. Of 24 non-accidental species of arthropods, all were judged to be troglophiles. All were scavengers except for 5 predators, one ectoparasite, and one parasitoid.

Experimental Testing Program In Elementary Chemistry: A Preliminary Report, Billie G. Broach, Howard L. Hodges

Journal of the Arkansas Academy of Science

An experimental testing program is described which utilizes questions that are partly computer composed, in addition to a section composed by the instructor, and a retesting option to the student. Results from a trial of the program for one term indicate that (1) course grades were improved, (2) the student withdrawal failure rate was unaffected, and (3) the employed students took greater advantage of the retest than did the unemployed students.

Pseudoscorpions Cavernicoles De La Macédoine, B. P. M. Ćurčić

International Journal of Speleology

A cavernicolous pseudoscorpion of the genus Neobisium Chamberlin 1930 is living in Kalina Dupka cave in the Bistra Highland of western Macedonia. This pseudoscorpion clearly differs from the other members of the subgenus Blothrus Schiodte 1849, and belongs to the new species N. (B.) princeps, the principal features of which are described in this study. The nearest relatives of this species are N. (B.) spelaeum (Schiodte) 1849, and N. (B.) stygium Beier 1931, both from Slovenian and Croatian caves. From chelal dentition N. (B.) princeps may be considered as the most primitive element of the princeps-stygium-spelaeum series. This new …

Branchiobdellids (Annelida: Clitellata) From Some Eastern North American Caves, With Descriptions Of New Species Of The Genus Cambarincola, Perry C. Holt

International Journal of Speleology

Branchiobdellids are found as epizoites on crustaceans of the orders Isopoda and Decapoda (cambarine crayfishes) in caves of eastern North America. Species that may be considered as troglobites, since they are not known from epigean waters, appear to be confirmed to truly troglobitic isopods and possibly a few troglobitic crayfishes from Florida and the Tennessee-Kentucky Highland Rim cave belt. The majority of the records of branchiobdellids from caves are of representatives of common epigean forms epizootic un crayfishes. Cross-referenced lists of branchiobdellids, their hosts and cave localities are presented. Some of the new species described are apparently troglobitic or troglophilic, …

The Certified Strains Of Subterranean Clover : Their Origin, Potential Use And Identification, B J. Quinlivan, C. M. Francis, M. L. Poole

Journal of the Department of Agriculture, Western Australia, Series 4

SUBTERRANEAN CLOVER originated in the countries surrounding the Mediterranean Sea and in parts of Western Europe.

Therefore it is not surprising that it grows well in the agricultural districts of Western Australia, for these regions have a typically Mediterranean climate with cool wet winters and hot dry summers.

The Genus Arrhopalites (Collembola: Sminthuridae) In The United States And Canada, Kenneth Christiansen

International Journal of Speleology

The members of the genus Arrhopalites (Collembola Sminthuridae) found in the U.S. and Canada are described and illustrated. These include six previously described forms and seven new species: A. altus, A. clarus, A. bimus, A. bellingeri, A. dubius, A. hirtus, and A. amarus. Two forms known only from incomplete specimens are described, but not named. Nine of the species are found in caves, but only four of these are at present unknown from surface localities. The characteristics of the genus are described and discussed, and the genus Pseudarrhopalites Stach is placed in synonymy with Arrhopalites. New methods are …

Contribution À La Systématique Des Stenasellinae D'Afrique (Crustacés, Asellotes), Guy Magniez

International Journal of Speleology

From 1897 to 1962, many species have been described as belonging to the genus Stenasellus Dollfus. Among all these the forms from Central Africa and one of Western Africa are not conform to the generic description of Racovitza 1924 obliging us to institute two new genera, Metastenasellus and Parastenasellus. The archaeic Asellota belong to the genus Stenasellus Dollfus, Johannella Monod, Metastenasellus nov.gen. and Parastenasellus nov. gen. are thus grouped in a sub family of Stenasellinae and the relationship between the different groups has still to be explained.

The Penetration Of Light Through Snow And Ice Cover, W. C. Croxton, W. B. Thurman, Theodore Shiffer

Journal of the Minnesota Academy of Science

During several months of each year, soil and bodies of water in high latitudes are separated from the enveloping atmosphere by a layer of snow and ice of varying thickness. The effects of this insulating layer are not well understood, having received relatively a rather surprisingly small amount of attention by ecologists. It is known that snow cover influences the heat exchange between the surface of the earth and the air. Ice is thought to interfere with gas exchange between water and air and with aeration by wave action to the extent that epidemic losses of fish life occur through …
