Ec17-11-80 Nebraska Outdoor Education Series: Plant A Tree, Joe Range, John D. Orr

University of Nebraska-Lincoln Extension: Historical Materials

Not all trees or shrubs can find a home in your yard or apartment. Help your child to discover a home for the tree or shrub he or she grows or receives. The greatest benefit of this Plant-A-Tree project is being close to a living plant. This project will: introduce five tree planters - one from each area of Nebraska, discuss the parts of tree seeds, give examples of how tree seeds travel, discuss preparation of soil, demonstrate how to grow a seedling tree from seed, demonstrate how to transplant a tree, and offer suggestions for activities and exhibits.

The Malaysian Fishing Gears And Methods, Mohamed Ibrahim Bin Haji Mohamed

Marine Affairs Theses and Major Papers

There are more than 40 types of fishing gears operated in Malaysia. These gears are classified locally into 11 gear groups based on their principles of operation. These gears have never been fully documented. This investigation attempts to document all the commercially important fishing gears in the country, the technical specifications, methods of operation, identify spacial differences in gears, operation and review the share/lay system operated in the industry.

Bringing Nature Into The Zoo: Inexpensive Solutions For Zoo Environments, David Hancocks

Zoos and Aquariums Collection

Animals in captivity have traditionally been kept in sterile and inappropriate environments. Typically this situation still prevails in zoos. Cages are designed only for restraint of the animals, expediency for the public, and convenient maintenance by keepers. The animals' behavioral needs are often ignored. By using nature as a norm, and by using natural materials, the spatial and temporal environment of a captive animal can be easily and greatly enriched. Several examples which have been used at Woodland Park Zoological Gardens are discussed. Their application and expansion are appropriate for most urban zoos.

Nongame Birds Of The Rocky Mountain Spruce- Fir Forests And Their Management, Kimberly G. Smith

T.W. "Doc" Daniel Experimental Forest

Spruce-fir forests in the Rocky Mountains consist mainly of Engelmann spruce and subalpine fir. The breeding avifaunas in these forests show remarkable consistency in composition along a latitudinal gradient from Montana to Arizona and New Mexico, and with avian communities in the Hudsonian life zone in Washington, Oregon, and California. Woodpeckers, corvids, and seed-eating finches are the most common components. Only the Golden Eagle and a few other raptors are threatened or endangered. Few species winter in these high mountain forests. The distribution of many species is controlled primarily by the vegetation physiognomy, a variable under the control of the …

Association Of Aquatic Insects To Macrophytes In An Agricultural Drainage Ditch, Kevin King, John Flypaa, Henry W. Quade

Journal of the Minnesota Academy of Science

The aquatic insects associated with five species of aquatic macrophytes were collected and identified from a drainage ditch in Le Suer County. A total of 21,160 specimens from eight orders were recovered with Diptera being the dominant. Tests of association, using the Coefficient of Community and Percent Similarity revealed a unique community associated with Potamogeton nodosus. Further, the authors found that the same information generated from the study could have been accomplished without the detailed taxonomy.

Inventory Of The Decapod Crustaceans (Crayfishes And Shrimps) Of Arkansas With A Discussion Of Their Habitats, Raymond W. Bouchard, Henry W. Robison

Journal of the Arkansas Academy of Science

The freshwater decapod crustaceans of Arkansas presently consist of two species of shrimps and 51 taxa of crayfishes divided into 47 species and four subspecies. The shrimps are represented by Macrobranchium ohione and Palaemonetes kadiakensis. The crayfish fauna is the largest of any state west of the Mississippi River reflecting the variety of habitats within Arkansas as a result of the geologic diversity in the state. The Ozark Plateaus and Ouachita provinces are dominated by the genus Orconectes, while in the Gulf Coastal Plain Procambarus is the most conspicuous group. Other crayfish stocks present include Cambarus, found predominantly in the …

Platte River Evapotranspiration: A Historical Perspective In Central Nebraska, Harold G. Nagel, M. Stanley Dart

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

A computational model was developed to estimate evapotranspiration (ET) in the Platte River ecosystem of central Nebraska. Data used in the model were mostly derived from the literature, although leaftemperature data were collected to estimate species transpirationcoefficients.

Preliminary estimates for ET are 35.5 in per yr during the April-tooctober growing season. Riparian forest accounted for 30% of the total ET, followed in order of importance by open-water evaporation, forested islands, herbaceous riparian-transpiration, sandbar evaporation, and then hcrbaceous island-vegetation, which accounted for only 10% of the total ET.

The Platte River has changed markedly during the last 40 years, with reduced …

The Rush Creek-Lisco Structural Basin, Garden And Morrill Counties, Nebraska, R. F. Diffendal Jr.

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Detailed field mapping of outcrops in southern Garden and Morrill counties, Nebraska, has revealed a drop of more than 60 m (200 ft) in 4.8 km (3 mi) in the elevation of the contact between the Brule Formation and the Ogallala Group as exposed on the east side of Rush Creek. Beds of silt, sand, siltstone, and volcanic ash locally dip to the northwest at angles up to 8.5°. The contact between the two formations cannot be seen on the west side of Rush Creek but beds in the Ogallala Group there dip to the north and northeast. Rocks north …

Floristic Analysis Of A Natural Area On The Lower Platte River Flood Plain, Donald A. Becker

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The vascular flora of an extinct river-island and inactive northchannel of the Platte River was studied from 1972-1978. Within a variety of vegetation types, including seral and sub climax flood plain forests, 289 species were identified from 200 genera and 70 families. The flora is dominated by four families, the Poaceae, Asteraceae, Cyperaceae, and Fabaceae, which contribute 40% of the species. Forty-eight species of woody plants occur in the area, including 17 species not previously reported in Dodge County. While much of the flora is composed of forest species (36.1%), significant numbers of ruderal and marsh species (each 19.4%) are …

Dirofilaria Immitis In The Wild Canids Of Illinois, Thomas J. Kick

Masters Theses

The heartworm, Dirofilaria immitis, is widespread in dogs in North America and has been reported in wild canids in many states. This is a report of this parasite in hearts removed from coyote, red fox and gray fox carcasses collected in Illinois. A total of 415 coyotes had a significantly higher infection rate (23.6%) than 225 red foxes (3.6%) and 99 gray foxes (3.0%). Infection rates in red foxes and coyotes were significantly higher in or near the Wabash Border Natural Division along the eastern side of the state, suggesting a relationship between infection rates and this region. The …

Polymorphisms, Linkage And Mapping Of Four Enzyme Loci In The Fish Genus Xiphophorus (Poeciliidae), D C Morizot, M J Siciliano

Faculty, Staff and Student Publications

Electrophoretic variants at four additional enzyme loci--two esterases (Est-2, Est-3), retinal lactate dehydrogenase (LDH-1) and mannose phosphate isomerase (MPI)--among three species and four subspecies of fish of the genus Xiphophorus were observed. Electrophoretic patterns in F1 hybrid heterozygotes confirmed the monomeric structures of MPI and the esterase and the tetrametric structure of LDH in these fishes. Variant alleles of all four loci displayed normal Mendelian segregation in backcross and F2 hybrids. Recombination data from backcross hybrids mapped with Haldane's mapping function indicate the four loci to be linked as Est-2--0.43--Est3--0.26--LDH-1--0.19--MPI. Significant interference was detected and apparently concentrated in the Est-3 …

Homeless Cats And Dogs Are Suffering And Dying

Close Up Reports

Last year more than 13 million homeless cats and dogs were euthanized at humane societies and municipal animal shelters. As a statistic, 13 million may be meaningless. But think of it another way. Think of the 13 million as individual animals with individual personalities--each with their own beating heart, each with their own wretched story of how they found their way to the animal shelter. Each one was an individual breathing creature whose life was ended because there was no home to go to.

Macroinvertebrate Populations In The Upper Mississippi River, David R. Mcconville

Journal of the Minnesota Academy of Science

The macroinvertebrate community of the Mississippi River near Monticell, Minnesota, was examined for 22 months. Quantitative bottom fauna information was obtained by use of concrete block artificial substrate sampling units. Representative organisms were obtained from seven (7) orders, 15 families and 35 genera of benthic macroinvertebrates. All taxa collected displayed definite seasonal trends. The Orders Trichoptera, Diptera, and Ephemeroptera were the most abundant groups collected, Trichoptera (Hydropsyche and Cheumatopsyche) were the dominant members of the benthic population in both numbers and biomass. Midges and blackflies were the dominant Diptera. Pseudocloeon, Stenonema, and Ephemerella were the most frequently collected mayflies.

Seasonal Abundance And Habitat Distribution Of Birds In Northeastern Arkansas, Earl L. Hanebrink, Alan F. Posey

Journal of the Arkansas Academy of Science

Bird sighting records from 1964 through 1978 for 17 northeastern Arkansas counties were compiled according to the seasonal status, relative abundance and habitat distribution of each species. The five seasonal occurrence categories and their relative species composition were: transient visitant (46.6%), summer resident (20.3%), winter resident (14.8%), permanent resident (17.2%) and winter visitant (1.0%). The seven seasonal abundance categories and their relative species composition were: very rare (13.9%), rare 15.9%), uncommon (30.7%), fairly common (10.5%), common (25.6%), very common (1.7%) and abundant (1.7%). Eleven habitat categories were included: campestrian, abandoned fields, forest edge, lowland woods, upland woods, riparian woods, marshes, …

The Realizing Character Of The Social Sciences, Andrew Larkin

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Because of successful construction of theories in the mathematical, physical, and biological sciences, and because of their unchallenged technological usefulness, the philosophy of science has concentrated on the formal and epistemological aspects of sciences. However, the less formal social sciences have had a greater impact on society. This realizing character of the sciences, i.e., their influence on society through policy (in the case of the social sciences), has been inadequately studied. In this paper the normative character of the social sciences is seen from the perspective of realization. Norms as internal and external criteria, which are entailed by realization, are …

Roman Concrete: The Ascent, Summit, And Decline Of An Art, Thomas Nelson Winter

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The evidence of the surviving literature and structure provides this chronology for the development of concrete: Fronto dates for us, by naming consuls, two aqueducts utterly devoid of concrete at 312 and 272 B.C. From Cato, who died in 149 B.C., we can discern that (a) concrete has now become the normal foundation for building, (b) limeburning is now an established trade, and (c) his recipe for cement is primitive-even medieval-and non-hydraulic. The year 140 saw the opening of the Marcian Aqueduct, its water-channel lined in non-hydraulic cement. Vitruvius, ca.25 B.C., describes different cement formulations for different purposes, even giving, …

The Ornithogeography Of The Great Plains States, Paul A. Johnsgard

Paul Johnsgard Collection

It has long been recognized that the Great Plains represent a major transition zone in the distribution patterns of North American birds; field guides traditionally have treated the 100° W. longitude meridian as a convenient dividing line between eastern and western faunas. Furthermore, this line rather neatly bisects the political subdivisions of the Great Plains, namely the "plains states" extending from North Dakota southward through South Dakota, Nebraska, Oklahoma, and Texas. Of these, Texas is the least typical, its climate and fauna is strongly influenced by the Gulf Coast on the east and the Chihuahuan desert on the west. As …
