Descriptive Ethology And Activity Patterns Of Black-Footed Ferrets, Tim W. Clark, Louise Richardson, Steven C. Forrest, Denise E. Casey, Thomas M. Campbell Iii

Great Basin Naturalist Memoirs

Aspects of the aboveground ethology and activity patterns of the black-footed ferrets (Mustela nigipes) are described for a population in northwestern Wyoming as a first step in building a descriptive ethogram and quantification of activity patterns. We observed at least 237 individual ferrets for 208 hr on 441 occasions from 2 December 1981 through 25 September 1984. Mainenance behaviors (locomotion, alert, grooming, and sunning, defecation and urination, digging, and predation) and social behavior (reproduction, ontogeny, maternal, play, agonistic) are described as well as some ferret-human interactions. Ferret vocalizations are subjectively described. We located ferrets during most months including …

Description And History Of The Meeteetse Black-Footed Ferret Environment, Tim W. Clark, Steven C. Forrest, Louise Richardson, Denise E. Casey, Thomas M. Campbell Iii

Great Basin Naturalist Memoirs

The black-footed ferret (Mustela nigripes) occupied area lies in the western Big Horn Basin, Park County, Wyoming. Cody, a nearby town, shows a record high temperature of 40.5 C and a low of -43.3 C, with 173 days each year below 0 C. Area geology is dominated by Absaroka volcanics. Soils are shallow (0.5 m) and underlain by unconsolidated gravels; well-drained, medium-textured clay-loams (ca 1 m in depth); or clays derived from shale parent materials. Vegetation is characterized by a wheatgrass-needlegrass shrubsteppe type (Agropyron/Stipa/Artemisia). Prior to white settlement, the area hosted a diverse large mammal community. …

Phomopsis-Resistanct Lupins : Breakthrough Towards The Control Of Lupinosis, W A. Cowling, J. G. Allen, P Mcr. Wood, J. Hamblin

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

Attemots to control lupinosis in sheep have been thwarted by the unpredictable occurence of the disease in the field. The complex interaction of the toxin-producing fungus (Phomopsis leptostromiformis) with its host (the lupin plant), together with variable weather and paddock grazing conditions, have made it difficult to predict when stock are in danger of contracting the disease. The risk of lupinosis discourages many farmers from growing lupins, despite the many potential benefits of including them in crop rotations.

A team of Department of Agriculture plant breeders, plant pathologists, and animal scientists set out in the mid 1970s to find resistance …

Grazing And Management Of Saltland Shrubs, C V. Malcolm, J. E. Pol

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

areas of bare saltland on farms need not be unproductive etesores. Many Western Australian farmers are now successfully growing salt-tolerant or halophytic shrubs such as bluebush (Maireana brevifolia), saltbushes (Atriplex spp.) and samphires (Halosarcia spp.) on these areas.

Department of agriculture trials and farmers' experience indicate that if saltland is planted with recommended shrubs, it can provide two months' valuable grazing for sheep during autumn and early winter, a time when paddock feed is scarce. Research by the Department has also identified a range of salt-tolerant shrubs suited to the various types of saltland.

Preventing Lupinosis With Phomopsis-Resistant Lupins, Jeremy G. Allen, W. A. Cowling

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

Lupinosis is one of the major livestock siseases in Western Australia. It is caused by stock eating toxins produced by the fungus Phomopsis leptostromiformis which colonises the stems of dead lupin plants.

In 975, the Department of Agriculture started a breeding programme to develop Phompsis-resistant lupins to overcome or control lupinosis. In the previous issue of this Journal the results of small plot evaluations of new lines of Phompsis-resistant lupins developed in this programme were reported. This article describes the first trial involving grazing of Phompsis-resistant lupins.

Phomopsis Infection Of Lupin Seed, D S. Petterson, P. Mcr. Wood

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

Early reports of lupinosis in Western Australia implicated infected stems and leaves of the sandplain or W,A. blue lupin (Lupinus cosentinii) as the main source of toxicity.

After the introduction of low alkaloid varieties of L. augustifolius, lupinosis continued to oddur on stubbles but random testing of seeds showed only low levels of Phomopsis leptostromiformis infection.

However in 1976, scientists at the University of Western Australia who were evaluating the use of an all lupin seed ration for drought feeding sheep encounted lupinosis in one of their trials.Seven per cent of the seed used was found to be infected …

Control Strategies For Annual Ryegrass Toxicity, W J. Burdass

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

In 982-83, annual ryegrass tocicity (ARGT) was estimated to have cost Western Australian sheep farmers between $7 and $8 million in total economic losses.

The disease can severely disrupt farming operations. Sheep must be checked daily and if affected moved to a 'safe' paddock. The availability of paddock feed is reduced, as is stock carrying capacity. Worry about the possibility of dramatic stock losses, and uncertainty about what decisions to make, are all stressful.

Stock losses from ARGT can be minimised by the use of selective herbicides to control ryegrass in pastures and crops. This breaks the disease cycle - …

Protein Enrichment Of Cereal Grains For Livestock, Andrew C. Dunlop, C. L. Mcdonald

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

Every year Western Australian farmers feed about 759,000 tonnes of cereal grain to livestock, mostly to sheep but also to dairy and beef cattle. These grains are fed as drought feeds, as supplements to augment poor quality or scarce paddock feed or in growth rations to attain higher levels of production. Many grains fed, however, have a low protien content and are therefore used inefficiently by animals.

Several methods of improving the low protien content of feed grains have been tested. They include the addition of lupin seed, spraying oats with urea and gassing oats with ammonia.

High Rates Of Photosynthesis In The Desert Shrub Chrysothamnus Nauseosus Ssp. Albicaulis, Tim D. Davis, N. Sankhla, W. R. Andersen, D. J. Weber, B. N. Smith

Great Basin Naturalist

Basic aspects of photosynthesis were investigated in white rubber rabbitbrush (Chrysothamnus nauseosus (Pallas) Britt. ssp. albicaulis), a common C₃ deciduous shrub native to arid regions of the western U.S. Under favorable field conditions, net photosynthesis (P_n) ranged from 36 to 73 mg CO₂ · dm ⁻² · hr⁻¹, which is relatively high for a woody species. The leaves from the actively growing flowering shoots exhibited higher P_n than those on the vegetative shoots. P_n also varied according to the age of the leaves and the location of the plants. P …

Documentation Of Whole-Farm Model For The Eastern Wheatbelt Of Western Australia, Ross S. Kingwell, David J. Pannell, David. A. Morrison

Grain and other field crops published reports

The Eastern Wheatbelt Model (EwM) is a hypothetical farm model, intended to be representative of farms in the eastern wheatbelt region. It is a model of an 'average' farm in an 'average' season. Nevertheless it is possible to substitute the resource mix of a 'real' farm for the •average' and to substitute various types of season for the 'average'.

Assumptions of 'average' farm resources and •average' season are based on opinions by WADA researchers and advisers. For the EWM, researchers and advisers at Merredin prescribed average resources for an eastern wheatbelt farm receiving a 300 mm average rainfall including 210 …

Spatial Patterns Of Plant Communities And Differential Weathering In Navajo National Monument, Arizona, Jack D. Brotherson, William E. Evenson, Samuel R. Rushforth, John Fairchild, Jeffrey R. Johansen

Great Basin Naturalist

Vegetation patterns in Navajo National Monument, Arizona, were studied over a five-year period from 1977 to 1981. Twelve distinct plant community types occur within the boundaries of the park. These communities are characterized and the dominant plant species of each are recorded. The relationships of parent material, soils, and moisture to plant communities are also discussed. It appears that discrete communities occupy soils of different characteristics, particularly with respect to amount of weathering of parent material.

Further Research Into Parrots And Fruit Damage, Department Of Agriculture, Western Australia

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

Parrits are major pests of Western Australia's South-West fruit growing industry. The amount of damage they can cause to ripening fruit in orchards varies from season to season, but in the last two years these colourful birds have become an even greater problem.

The Agriculture Protection Board has started further research aimed at determining how wxtensive damage to fruit can be prevented.
