A Descriptive Study Of Range Livestock Operations In The Somali Central Rangelands, Abdinasir M. Abdulle
A Descriptive Study Of Range Livestock Operations In The Somali Central Rangelands, Abdinasir M. Abdulle
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Information on livestock operations, particularly what kind of livestock operations are practiced in the Somali central rangelands, and how these operations differ for different herders in different vegetation types and farming systems, could serve as a major tool in making management decisions. This study provides a detailed description of range livestock operations in the Somali Central Rangelands. It also answers some important management questions.
Range livestock operations were inventoried through personal interviews with the owners and herders. Data are supplemented by previous nation-wide and regional survey statistics. Herd productivity data which include herd structures, age, age-related sales, slaughters, gifts, and …

First paragraphs of the introduction:
In Fortführung der Forschungsreisen der russischen Floristen und Pflanzengeouraphen im vorigen und Anfang dieses Jahrhunderts wurden erste Expeditionen zur systematischen Erforschung der Naturressourcen der Mongolei in den 20er und 30er Jahren durchgeführt. Sie wurden von der Akademie der Wissenschaften der UdSSR und der Akademie der Wissenschaften der MVR (vorher Wissenschaftliches Komitee der MVR) organisiert. Auch die von der Geographischen GeselIschaft und der Akademie der Wissenschaften der UdSSR durchgeführten Expeditionen zur Erforschung der natürlichen Bedingungen und der Landwirtschaft in der Mongolei schufen Möglichkeiten zur Entwicklung der geobotanischen Forschungsrichtung (vgl. GUBANOV u. HILBIG 1989).

Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford
Waterlogging : How It Reduces Plant Growth And How Plants Can Overcome Its Effects, Tim Setter, Bob Belford
Journal of the Department of Agriculture, Western Australia, Series 4
Lack of oxygen is the major cause of limited plant growth in waterlogged soils. When soils become waterlogged less gas diffuses to and from the roots through the soil pores; there are changes in concentrations of mineral elements in soil solutions; and toxic products of roots and soil microorganisms begin to accumulate. These changes adversely affect germination, growth and development of plants.

Plant Growth And Survival In Saline, Waterlogged Soils, Ed Barrett-Lennard, Neil Davidson, Richard Galloway
Journal of the Department of Agriculture, Western Australia, Series 4
Waterlogged soils in Western Australia are often salt-affected. Recent research has shown that the interaction between waterlogging and salinity has a far greater adverse effect on plant groivth and survival than either of these two factors individually. The consequences of the combined effects of salt and waterlogging for most plant species are increased salt uptake, reduced growth, chlorosis (yellowing of leaves), defoliation, and death. Salt sensitive agricultural species (nonhalophytes) are more severely affected by this interaction than salt tolerant species (halophytes).
Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson
Integrated Control Of Soil Insect Pests Of Potatoes, Stewart Learmonth, John Matthiesson
Journal of the Department of Agriculture, Western Australia, Series 4
One of the more difficult aspects of growing potatoes in Western Australia is controlling soil insect pests. These pests have become more troublesome because the highly effective and persistent organochlorine insecticides previously used to control the main soil pests, African black beetle and whitefringed weevil, were deregistered for agricultural use in 1987. Entomologists from the Department of Agriculture and CSIRO in Western Australia are collaborating to develop new management strategies for these pests that rely less on the use of chemical insecticides

Journal of the Department of Agriculture, Western Australia, Series 4
Waterlogging is highly variable, both between years and within paddocks. This residts in uncertainty as to whether a paddock should be cropped in a particular year, and whether different management should be used on waterlogged areas within a paddock
A study has determined what are the most important causes of waterlogged soils.
Floristic Survey Of Remnant Vegetation In The Dandaragan Area, Western Australia, Edward Arnold Griffin
Floristic Survey Of Remnant Vegetation In The Dandaragan Area, Western Australia, Edward Arnold Griffin
Resource management technical reports
A study involving the documentation of the extent and floristic composition of patches of native vegetation left uncleared by agricultural development is described. Floristic regions were defined in the study area by detailed analysis of the floristic data. The concentration of the major conservation reserves in only a few of these regions left the floristic variation of most of these regions poorly represented conservation reserves. About 13 percent of the private property remains uncleared.
Effects Of Lake Management On Chemical, Physical, And Phycological Characteristics Of A Hypereutrophic Reservoir, Kaye J. Surratt
Effects Of Lake Management On Chemical, Physical, And Phycological Characteristics Of A Hypereutrophic Reservoir, Kaye J. Surratt
Masters Theses
Lake Charleston is a 1.1 billion gallon capacity side channel reservoir which was constructed in 1982 as a public drinking water supply for the City of Charleston in Coles County, Illinois. Past studies of the lake indicated an increase in eutrophication and the capacity to support large algal populations. Recent lake management practices include copper sulfate applications as an algicide and aeration to reduce flavor and odor.
In order to assess present lake status and to evaluate the effectiveness of lake management practices, two lake sites were sampled on a weekly basis from May to October, 1989. Chemical, physical, and …
