In Vitro Experiments On Totipotency Of Dacus Carota, Karl L. Ruser

Journal of the Minnesota Academy of Science

The intent of this project was to induce the totipotency of carrot cells in tissue culture. The information gathered would be applied to work with woody plants. Differentiated cells removed from the root were cultured in vitro using a modified White's medium. Callus was initiated and successfully sub cultured. Roots and the production of chlorophyll have been initiated in the cultures. Because some specialized equipment and facilities for tissue culture were not available at the beginning of the project, it took considerable time to gather and improvise them. A roller tube culture mixer was constructed, using the mechanism from a …

Blue-Green Algal (Cyanophyta) Toxins, Charles P. Mason

Journal of the Minnesota Academy of Science

In the past toxin production by blue-green algae has been demonstrated by feeding large quantities of algae to vertebrates and observing symptoms leading to animal death. It was the purpose of this investigation to develop a more convenient way to test for the presence of an alga toxin using instead of vertebrates, other algae and those organisms with which it lives and competes in fresh water habitats. Using axenic algae cultures and three different agar media MBL, DAA and NA, the latter to check for bacterial contamination, algae were streaked on the agar surface in petri dishes to form a …

Shovelnose Sturgeon (Scaphirhynchus Platorhynchus) In The Minnesota River, Paul Durkee, Brian Paulson, Robert Bellig

Journal of the Minnesota Academy of Science

The shovelnose sturgeon, Scaphirhyncus platorhyncus, according to Eddy and Underhill (1974) has not been reported from the Minnesota River for a number of years. Recently, Wilcox et. al. (1978) reported a single adult taken in 1974, and two others in 1976. Our survey of the fishes in the Minnesota River showed a substantial number of shovelnose sturgeon, at least in certain locations. Twenty specimens were taken in 42 gill net days. Other data obtained included food habits and age-length relationships. Food habits were determined through volumetric analysis of stomach contents, and ages were obtained by sectioning the marginal pectoral fin …

Synthesis Of 2-Aminomorphine And 2-Aminocodeine. Reduction Of Aromatic Nitro Groups With Formamidinesulfinic Acid. / Nithiananda Chatterjie, Arlene Minar And Donald D.

Chemistry Faculty Publications

Our interest in the stereoselective reduction of the carbonyl groups of various oxymorphone derivatives with formamidinesulfinic acid (FSA) led to a result indicating that dihydrocodeinone underwent ring-oxygen scission under the conditions of reduction with this reagent. This observation4 has prompted interest and speculation as to the scope and mechanism of this reaction by others, as well as ourselves

Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The wolf (Canis lupus) is a wide-ranging social carnivore with a complex spatial organization (MECH, 1972; 1973). The precise manner in which this organization is maintained is unknown, but territory advertisement using olfactory and acoustic modes seems to be involved.

The acoustic mode includes primarily howling. Within a wolf pack, howling may be useful to reassemble separated members (MECH, 1966; THEBERGE & FALLS, 1967), and may communicate information on individual identity, location, and other behavioral and environmental contingencies (THEBERGE & FALLS, 1967). Between packs, however, howling may serve to advertise territory, communicating the locations of packs and thus …

Fisheries Report No. 37 - An Inventory Of The Marine Resources Of The Bunbury Marine Area And Geographe Bay, Michael H. Walker

Fisheries Research Reports

The marine resources of the Geographe Bay/Bunbury marine area were investigated using a variety of fishing gear i.e. set lines, set nets, trawls, ring nets, beach seines, hand lines, trolling lines, traps and light attraction at night. All the ftsh species caught were documented as to breeding state and food habits.

Commercial species encountered as adults during fishing operations were: bronze whaler, whiskery and gummy sharks, Westralian jewfish, Australian herring, skippy, flathead, oriental bonito, blue and sandy sprat, pilchard, mulloway, whiting, yellowtail scad, flounder, and leatherjacket and as juveniles were: skippy, yellowtail scad, tailor, southern sea garfish, pilchard, blue and …

Fisheries Report No 33 - The Western Rock Lobster Fishery 1975 - 1976, G. R. Morgan, E H. Barker

Fisheries Research Reports

iTshe fishery for the western rock lobster Panultrus ecygnus one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. …

Distributional Survey Of The Fishes Of Ten Mile Creek In Southeastern Arkansas, Carl D. Jeffers, Edmond J. Bacon Jr.

Journal of the Arkansas Academy of Science

A survey of the fishes of Ten Mile Creek was conducted during 1976 to 1979. The ichthyofauna of Ten Mile Creek is typical of lowland drainage systems in southeastern Arkansas. Fifty-three species representing 13 families and 23 genera were collected. Etheostoma parvipinne was locally abundant in the headwaters, and other vulnerable or rare species included Notropls maculatus, Fundulus notti, Fundulus chrysotus, Erimyzon sucetta, Moxostoma poecilurum, and Lepomis punctatus. Eight specimens of Notropis hubbsi were collected.

Alternatives To Laboratory Animals: Definition And Discussion, Andrew N. Rowan

The Institute for the Study of Animal Problems [ISAP]

The origins of the concept of "alternatives" to the use of animals in research may be traced back to the 1800's and the furore about using live animals in surgical and other experiments. Some of the animal protection societies in England were prepared to accept animal experimentation provided it was performed under anesthesia. Even Dr. Marshall Hall, who championed the spread of experimental medicine in 19th century England, considered it necessary to control and prevent unwarranted, inept and cruel experimentation (French, 1975). The concept of alternatives has developed in the 20th century to encompass not only the reduction (prevention) of …

Metcalf-Hatch Fact Sheet, Henry Spira

Metcalf-Hatch Campaign

The Metcalf-Hatch Act forces tax supported pounds and shelters to turn over unwanted cats and dogs to New York laboratories. This creates difficulties for shelters/pounds. People who are aware of Metcalf-Hatch (MH) will tend to abandon animals rather than risk having them recycled into labs. And this places additional tax burdens on communities for rounding up abandoned strays. The cost of stray animals is already $400 million a year in the USA.

Fisheries Report No 34 - The Status Of The Salt-Water Crocodile In The Glenelg, Prince Regent And Ord River Systems, Kimberley, Western Australia, A. A. Burbidge, H. Messel

Fisheries Research Reports

Counts were made of Salt-water Crocodiles (Crocodylus porosus) in the estuarine portions of the Glenelg, Prince Regent and Ord River systems of the Kimberley Division, Western Australia. During the survey 581 crocodiles were seen, including 143 hatchlings. The number of non-hatchling crocodiles in present the Glenelg system is estimated to be 200 to 259, in the Prince Regent 190 to 246 and in the Ord 235 to 306 (95% confidence limits).

The number of non-hatchling crocodiles present in the six Kimberley river systems now counted is estimated to be between 957 and 1243 (95% confidence limits) and we believe that …
