Fisheries Report No 9 - The Fauna And Flora Of Monte Bello Islands, A. A. Burbidge Dr

Fisheries Research Reports

Two visits were made to the Monte Bello Islands in 1970 and 1971.

The aim of the visits was to examine the islands for the presence of native mammals and other fauna, and to explore the possibility of re-establishing fauna now extinct,

The first survey was carried out in conjunction with a more detailed examination of the Dampier Archipelago. The fisheries patrols vessel "Dampier" was used to reach the islands and as a base. Personnel were R. Johnstone (W.A. Museum), E.J. Little and J.D. Harman (crew of the "Dampier"), R.F. Dear and A.A, Burbidge, all from the Department of Fisheries …

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr

Fisheries Research Reports

Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.

The first Europeans to see the area were the exploring party led …

Studies Of Arundinaria: Experimental Induction Of Flowering And Additional Observation In The Field, Daniel L. Marsh

Journal of the Arkansas Academy of Science

Arundinaria has been observed for three successive seasons at a site near Amity, Arkansas. In advance of the 1971 flowering period rhizomes were taken from the field, pruned, and placed either in an environmental chamber or in the greenhouse in water or in sandy soil. Flowering occurred under each condition, but was most rapid and profuse in transplants growing in sandy soil in the greenhouse. Observations point to the possibility of induction of flowering or to the possible existence of an annually flowering race. Possible economic uses are considered.

Survey Of The Vascular Flora Of Poinsett County, Arkansas, Michael I. Johnson

Journal of the Arkansas Academy of Science

A survey of the vascular flora of Poinsett County, Arkansas was made over a period of 13 months. The fifteen field trips taken were planned to include representative soil associations and geographic areas within the county. Three hundred sixty-three species and varieties from eighty-three families were collected or examined.

Internode Growth In The Aquatic Macrophyte, Hippuris Vulgaris, Mary Ellen Bland

Journal of the Minnesota Academy of Science

ABSTRACT -An analysis of internode lengths in the Hippuris stem is represented by a four phase growth curve, The two parameters which infl~ence this pattern of internode lengths are the number of cells per internode and the length of the individual cells within the internode. In the ontogeny of the Hippuris stem cell length and cell number influence internode length in the distal portion of the stem while in the basal portion of the stem cell number is the major factor affecting internode length. The pattern of stem growth in Hippuris differs from that of Elodea in that the cell …

Relation Of Hybridity To The Expression Of Gene Dwarf-1 In Maize Coleoptile Growth, Martin C. Goffinet

Journal of the Minnesota Academy of Science

ABSTRACT - The plants used in this study were two inbred strains of maize and their hybrid. Each strain segregated for the mendelian gene dwarf-1, approximating a ratio of three normal to one dwarf, with l 00 per cent penetrance. The length of each of fifty coleoptiles per strain was determined at planting and after emergence of the seedlings until maturity of that organ. The dwarf seedlings were compared with their normal sibs within each strain to determine the degree of expression of the mutant gene. The growth parameters determined from the measurements were: l) total elongation of coleoptile after …

Aphanizomenon Elenkinii Kissel, An Interesting Variation, Hibbert Hill

Journal of the Minnesota Academy of Science

ABSTRACT-A mature bloom of Aphanizomenon elenkinii Kissel, type II, appeared in a local lake in late April, early May, 1971. The appearance of the alga in late spring and changes in the structures of the alga from those previously reported are of interest.

The Biological Activity Of Phytotoxic Extracts From Corynebacterium Sepedonicum, Doran W. Pearson

Open Access Master's Theses (through 2010)

Isolation of a phytotoxin from the ring rot pathogen of potatoes, Corynebacterium sepedonicum, had previously been reported by Strobel (21). The first phase in our study was to investigate more extensively the general nature of this compound. The phytotoxin could possibly be a specific compound associated only with the ring rot pathogen. However, the possibility that the substance could be obtained from sources other than the bacterium had not been completely eliminated. In an attempt to answer this question, three extracts were purified and compared. First, compounds were isolated from a broth culture of bacteria in the manner described …

A Description Of Vascular Plant Species From An Area In The Central Sierra Nevada Foothills Of California, Thomas Carter Hensel

University of the Pacific Theses and Dissertations

Much work has been done on the remarkably diverse flora of California but few specific studies of the foothills of the Central Sierra Nevada Range have been undertaken. One such area is Calaveras County, a region rich in the early history of California.

The site chosen for this study ranges from approximately 2350 to 2700 feet in elevation. It is well defined by survey and accessible at all times of the year. The primary objective of the study was to determine what vascular plant species occur naturally in the area. This was accomplished by extensive collections made from April 1970 …

Observations On The Establishment Of Seedlings Of Phoradendron Californicum On Prosopis Juliflora, Richard L. Null

Dissertations and Theses

The mistletoe Phoradendron californicum is a common parasite on the mesquite plant Prosopis juliflora. Seeds of the parasite are deposited upon the host plant by birds and perhaps other agents. Normally seedlings of the parasite become established when the elongating radicle of the embryo comes into contact with a host branch and forms a holdfast. From the underside of the holdfast the primary haustorium enters the host tissue and establishes the parasitic union. Later the aerial portion of the parasite develops. Some seeds of P. californicum follow a different sequence; they stimulate the host to produce gum in the tissue …

A Comparative Study Of The Head And Thoracic Osteology And Myology Of The Skinks Eumeces Gilberti Van Denburgh And Eumeces Skiltonianus (Baird And Girard), David F. Nash, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The differences observed from the osteology and myology are few and subtle.

Neither species is consistent in having all of the anatomical characters equal. E. skiltonianus, however, is more variable than gilberti. This species: 1. exhibits a wider range of variation in the number of slips of the intermandibularis anterior; 2. has two distinct bundles of the depressor mandibularis; and 3. has variation in the anterior suture pattern of the frontal, nasal, prefrontal and maxilla elements. E. gilberti on the other hand has: 1. only one distinct bundle of the depressor mandibularis; 2. a frequent reduction of the relative size …
