Fire Weather : A Guide For Application Of Meteorological Information To Forest Fire Control Operations, Mark J. Schroeder, Charles C. Buck Jan 1970

Fire Weather : A Guide For Application Of Meteorological Information To Forest Fire Control Operations, Mark J. Schroeder, Charles C. Buck

The Bark Beetles, Fuels, and Fire Bibliography

Weather is never static. It is always dynamic. Its interpretation is an art. The art of applying complex information about weather to the equally complex task of wildland fire control cannot be acquired easily-especially not by the mere reading of a book. The environment is in control in wildland firefighting. Free-burning fires are literally nourished by weather elements, atmospheric components, and atmospheric motion. Outguessing mother nature in order to win control is an extremely difficult task. We need to soothe her with understanding. We have attempted to present information in such a way that your daily and seasonal awareness of …


Fertiliser Recommendations For Citrus : Detailed Fertilizer Programmes For Citrus Growers, N H. Shorter, J. E. L. Cripps Jan 1970

Fertiliser Recommendations For Citrus : Detailed Fertilizer Programmes For Citrus Growers, N H. Shorter, J. E. L. Cripps

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

CITRUS growers should adopt a well balanced fertiliser programme to safeguard tree health, cropping and fruit quality. While moderate dressings are a wise insurance in most situations the rates required vary with tree age and soil type.

The recommendations are given in detail in the tables in this article.

Influence Of Urea On The Fermentation Pattern & Nutritive Value Of Corn Silage, John Shirley Jan 1970

Influence Of Urea On The Fermentation Pattern & Nutritive Value Of Corn Silage, John Shirley

Masters Theses & Specialist Projects

The effects of chemical additives on the fermentation pattern and subsequent feeding value of corn silage was investigated over a two year period. Corn plants harvested in August 1967 (Experiment I) were ensiled with no additive, 3.50 per cent area, or urea-mineral mix supplying an equal amount of urea. Those harvested in August 1968 (Experiment II) were ensiled with no additive, 0.50 per cent urea, or 0.75 per cent urea. The nutritive value of these silages was evaluated chemically and by lactation trials.

:he addition of urea alone, or in combination with minerals elevated the initial pH and buffered against …

Bats Of The Genus Myotis From Western Mexico, With A Key To Species, J. Knox Jones Jr., Hugh H. Genoways, Larry C. Watkins Jan 1970

Bats Of The Genus Myotis From Western Mexico, With A Key To Species, J. Knox Jones Jr., Hugh H. Genoways, Larry C. Watkins

University of Nebraska State Museum: Mammalogy Papers

Distribution and variation in Mexican representatives of the vespertilionid bat genus Myotis have not been well documented. The most complete modern systematic treatment of these bats is that of Miller and Allen (1928), although these authors examined relatively few specimens and some of their taxonomic conclusions have been modified by more recent studies (see especially Findley, 1960; Findley and Jones, 1967; Genoways and Jones, 1969). In the past two decades, field representatives of the Museum of Natural History at The University of Kansas have obtained large collections of mammals in western Mexico, principally in the states of Jalisco and Sinaloa. …

Adaptations For Flight In Bats, Terry A. Vaughan Jan 1970

Adaptations For Flight In Bats, Terry A. Vaughan

Fondren Science Series

Flight developed independently in three groups of vertebrates. From reptilian ancestry arose the pterosaurs and the birds, and bats evolved from primitive mammals. Pterosaurs became extinct, together with their relatives the dinosaurs, more than 75 million years ago, whereas both birds and bats are still remarkably successful today. Pterosaurs probably used mostly gliding flight, but birds and bats use primarily flapping flight. Birds and bats use different styles of flight, probably as a result of the different ways in which these animals perceive their environments. Vision, which is used by birds for orientation, allows the recognition of obstacles at considerable …


Diurnal Retreats Of Bats, W. W. Dalquest, Dan W. Walton Jan 1970

Diurnal Retreats Of Bats, W. W. Dalquest, Dan W. Walton

Fondren Science Series

The forelimbs of bats are so highly modified for flight that they are of little value for terrestrial locomotion. Deprived of all but limited use of the front feet in terrestrial activity, roosts or resting sites are also limited. All bats are primarily nocturnal and most of them spend the day in elevated, secluded retreats. Elevation is critical, for some bats show limited ability to take flight from flat, horizontal surfaces. Many bats, however, do show marked agility on the ground, and are quite capable of gaining flight from flat, horizontal surfaces. There is little correlation between taxonomy and roosting …


Some Observations On Ecto- And Endoparasites Of Chiroptera, John E. Ubelaker Jan 1970

Some Observations On Ecto- And Endoparasites Of Chiroptera, John E. Ubelaker

Fondren Science Series

The various groups of organisms associated with bats have caught the interest of many investigators. Noteworthy is the review by Stiles and Nolan (1931) in which all known parasites of bats were listed. Allen (1939) presented a general introduction to the parasites of bats in which he emphasized the arthropods. Other references to parasites of bats are concerned with particular groups. In this paper I hope to acquaint the reader with these groups and to indicate some of the interesting relationships that have been elucidated. The tremendous number of papers published concerning organisms associated with bats precludes the inclusion of …


The Role Of Karyotypes In Phylogenetic Studies Of Bats, Edwin Gould Jan 1970

The Role Of Karyotypes In Phylogenetic Studies Of Bats, Edwin Gould

Fondren Science Series

There are several reasons for using chromosome form and number (the karyotype) in phylogenetic studies. Since the material of the genotype forms part of the chromosomes, the karyotype is less influenced by external factors than are other morphological and physiological characteristics (John and Lewis, 1966). There are, however, two obvious ways natural selection can act on changes in the karyotype. The first involves the ability of the karyotype to proceed through the mechanics of mitosis or meiosis. If mitosis is blocked the cell line would die. If the rearrangement interferes with proper functioning of meiosis the result is reduced or …


A Statistical-Mechanical Model For The Binding Of Flexible Ligands To Proteins, Nora Dawn Laiken Jan 1970

A Statistical-Mechanical Model For The Binding Of Flexible Ligands To Proteins, Nora Dawn Laiken

Student Theses and Dissertations

In this dissertation, a theoretical model is presented for the binding of flexible ligands to proteins. The model explicitly accounts for the ability of these chain-like molecules to bind in a large number of configurations (including many in which not all segments are in contact with the protein) and therefore is quite different from the theory of multiple equilibria which commonly is used to analyze such interactions. The latter assumes that the ligands bind rigidly to point binding sites, neglecting the internal degrees of freedom of the bound molecules. Comparisons of binding data calculated using the present model with those …


Caste Regulation In The Termite, Neotermes Jouteli (Banks), Richard David Nagin Jan 1970

Caste Regulation In The Termite, Neotermes Jouteli (Banks), Richard David Nagin

Student Theses and Dissertations

The southern Florida termite Neotermes jouteli (Kalotermitidae) was found to provide exceptionally suitable material for the study of caste regulation, with special reference to the regeneration of reproductive forms. It was possible to collect entire natural colonies of this termite, including the reproductive pair, and to maintain them for long periods in the laboratory. In this way the characteristics of individual colonies could be studied in a way not done in most earlier work on caste regulation. Most interesting was the finding that the capacity to regenerate lost reproductive forms was a characteristic of individual colonies. By removing groups of …


Variability In The Firing Of Nerve Impulses In Eccentric Cells Of The Limulus Eye, Robert Shapley Jan 1970

Variability In The Firing Of Nerve Impulses In Eccentric Cells Of The Limulus Eye, Robert Shapley

Student Theses and Dissertations

This thesis is concerned with the source and characteristics of variability in the discharge of impulses by neurons. The neuron in which variability was studied is the eccentric cell in the compound eye of the horseshoe crab, Limulus polyphemus. In Part I a theory is presented which accounts for the variability in the response of an eccentric cell to light. The main idea of this theory is that the source of randomness in the impulse rate is "noise" in the generator potential. Another essential aspect of the theory is the view that the process which codes the generator potential into …


High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter Jan 1970

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

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

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

Weed Control Research Pays Dividends, G R W Meadly Jan 1970

Weed Control Research Pays Dividends, G R W Meadly

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

On my bookshelf is a handbook entitled "War on Weeds" or "How to Double our Food Supply."

In many of these countries experiments have been made to ascertain as far as possible the exact damage done by weeds to crops.

Result: In all the experiments, whether made in England or abroad, the mean loss was over 50 per cent.

The level of loss is equally true today, but the methods at our disposal for handling weeds have improved tremendously.


Urea Block Supplements For Stubble, H E. Fels, R. J. Parkin Jan 1970

Urea Block Supplements For Stubble, H E. Fels, R. J. Parkin

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

THERE was a great deal of controversy throughout the summer of Western Australia's 1969-70 drought over the feeding of supplements other than grain to grazing sheep.

This report summarises some of the experiments carried out by this Department to investigate various artificial means of supplementing sheep grazing stubbles and dry summer pastures.

Further details of the experiments can be obtained by contacting the authors.

The results failed to demonstrate economic responses to urea supplements for grazing sheep.


Reproduction And Growth Of The Tule Perch Hysterocarpus Traskii (Gibbons) With Notes On Its Ecology, David Scott Bundy Jan 1970

Reproduction And Growth Of The Tule Perch Hysterocarpus Traskii (Gibbons) With Notes On Its Ecology, David Scott Bundy

University of the Pacific Theses and Dissertations

This study was initiated to obtain information about the natural history of the tule perch before greater reduction in population has occurred. The studies of Hopkirk (1962) and Turner (1966) did not include information on reproduction, development, and growth of embryos within the ovarian sac, and the growth of the tule perch and, secondly, to supplement the work of Hopkirk and Turner concerning color variation and food habits.


Developmental Changes In Organ Systems Of Transforming Anuran Larvae, Muriel Humphrey Marshall Jan 1970

Developmental Changes In Organ Systems Of Transforming Anuran Larvae, Muriel Humphrey Marshall

University of the Pacific Theses and Dissertations

Despite an enormous amount of information on the biochemical and physiological changes of amphibian metamorphosis, information about the general anatomy of anuran larvae is not readily available. The present study is a comparison of the general morphological changes during metamorphic climax of three anuran species belonging to three different families. This anatomical information is designed to assist those wishing to correlate cellular and chemical events with the corresponding morphological events.


Immunodiffusion And Immunoelectrophoretic Studies On Trypanosoma Lewisi (Kent) During The Course Of An Infection In The Albino Rat, Rattus Rattus, Carol Louise Perkins Drew Jan 1970

Immunodiffusion And Immunoelectrophoretic Studies On Trypanosoma Lewisi (Kent) During The Course Of An Infection In The Albino Rat, Rattus Rattus, Carol Louise Perkins Drew

University of the Pacific Theses and Dissertations

Immunoelectrophoresis revealed an antigen-antibody response between 4 day metabolic products and 8, 12 and 16 day sera and between 4 day trypanosomal extract and 16 day serum.

Metabolic products from trypanosomes incubated at room temperature do not appear to be antigenic.

The limitations of immunodiffusion are discussed in reference to the results. It is suggested that some of the antibodies to metabolic products may be of the precipitating type while others are not.

Since a faint reaction also occurred between 4 day trypanosomal extract and 16 day serum, it may be concluded that metabolic products contribute to only a portion …

A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin Jan 1970

A New Tribe Of Saber-Toothed Cats (Barbourofelini) From The Pliocene Of North America, C. Bertrand Schultz, Marian R. Schultz, Larry D. Martin

Bulletin of the University of Nebraska State Museum (1924–2023)

A new genus of Pliocene Saber-toothed felid, Barbourofelis, is proposed and two new species B. fricki and B. morrisi are described. These two forms and other described material represent an unusual lineage of felids with long sabers, shortened crania, and massive postorbital bars. The tribal name Barbourofelini is proposed for this lineage which is presently known in North America from deposits ranging in age from Clarendonian through Kimballian. The Barbourofelini apparently migrated from Eurasia to North America in the Late Miocene or Early Pliocene. Sansanosmilus of the French Vindobonian appears to represent the ancestral stock of these cats. The …


Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling Jan 1970

Part I - Controlling The Soil Moisture Environment Of Transpiring Plants, Part Ii - Prediction Of Leaf Temperature Under Natural Atmospheric Conditions, Charles T. Haan, Billy J. Barfield, Robert Edling

KWRRI Research Reports

Part I

A technique for controlling the soil moisture potential in the root zone of transpiring plants was developed. The method uses the principles of unsaturated flow through a porous media to develop the desired moisture potential. In the case of non-steady state transpiration, the maximum possible fluctuation in the soil moisture potential can be determined by the techniques presented.

Part II

Two implicit leaf temperature prediction equations were derived from the energy balance approach. The equations define sensible and latent heat transfer from a plant population as a two step process:

  1. Transfer between the plant leaf and the canopy …
