Fisheries Report No 12 - Results Of A Biological Survey Of A Proposed Wildlife Sanctuary At Dragon Rocks Near Hyden, Western Australia, N. L. Mckenzie, A. A. Burbidge, N. G. Marchant
Fisheries Research Reports
In 1972, three visits were made to an area of vacant crown lam 30 kilometres south-south~east of Hyden, Western Australia.
A preliminary survey was made in April 1972 and following this recommendations were made on the equipment and staff required for a detailed survey of the vegetation and animals.
From the 30th July to the 4th August 1972, a team from the Fauna Research Branch of the Department of Fisheries and Fauna began a detailed fauna survey.
Between the 20th August and the 25th August 1972, the fauna survey was continued am a botanist from the Western Australian Herbarium undertook …

Observation On Natural Outcropping In The Tomato (Lycopersicon Esculentum L.) In Northwest Arkansas, Alvin F. Reeves
Observation On Natural Outcropping In The Tomato (Lycopersicon Esculentum L.) In Northwest Arkansas, Alvin F. Reeves
Journal of the Arkansas Academy of Science
A single tomato plant homozygous for the recessive anthocyaninless mutant, ae, was grown in the middle of an experimental tomato plot at the University of Arkansas Agronomy Experimental Station Farm in Fayetteville. Progeny tests of seeds harvested from this plant indicated that only 0.7% of the seeds were the result of outcrossing to other plants

Natural Areas And Reference Collections For Environmental Education In Some Arkansas Schools, Jewel E. Moore
Journal of the Arkansas Academy of Science
A survey of 20 school campuses throughout Arkansas showed that most lack natural areas for outdoor environmental education. For most Arkansas schools no checklists of local plants are available, and there are no reference collections at the schools. Projects are underway at State College of Arkansas to establish herberia for the woody plants of Arkansas and the vascular plants of Faulkner County.
The Effect Of The Herbicide Glyphosate On The Growth Of Selenastrum Capricornutum, Judith Susan Eisen
The Effect Of The Herbicide Glyphosate On The Growth Of Selenastrum Capricornutum, Judith Susan Eisen
Undergraduate Honors Capstone Projects
The herbicide glyphosate (MON-0139), an isopropylamine salt of N- (phosphonemethyl)glycine, was tested to determine its effects on the growth of the fresh water green alga Selenastrum capricornutum. Experiments were carried out to determine algicidal, algistatic, and inhibitory concentrations of the compound.
Concentrations from 5 ppm to 1000 ppm were inhibitory to the growth of the alga, but the effects were algistatic, rather than algicidal. At concentrations from 0.1 ppm to 1.0 ppm the growth of the alga was stimulated by the presence of the herbicide, while at concentrations from 0.001 ppm to 0.05 ppm the effects of the herbicide were …

Fleas Of Venezuela, Vernon J. Tipton, Carlos E. Machado-Allison
Brigham Young University Science Bulletin, Biological Series
Forty-three species of fleas were collected in Venezuela by personnel of the Smithsonian Venezuelan Project. Currently there are fifty-two species of fleas known from Venezuela. Four new taxa are described: Hormopsylla cryptica, Ctenidiosomus perplexus, Adoratopsylla antiquorum rara and Adoratopsylla antiquorum recta. The females of Adoratopsylla antiquorum discreta Jordan and Rothschildopsylla noctilionis (Costa Lima) are described. The families Stephanocircidae (Cleopsylla, Craneopsylla, Plocopsylla, Sphinctopsylla) and Pygiopsyllidae (Ctenidiosomus) are reported from Venezuela for the first time. Two male specimens of the genus Orchopeas constitute the first record of this genus in South America and records of species of the …
