Initial Effects Of Deforestation On Herbaceous Species Composition In Grassy Woodlands Of The Northern Tablelands, Nsw Australia, Chris R. Chilcott, N. Reid, R. D. B. Whalley Dec 2021

Initial Effects Of Deforestation On Herbaceous Species Composition In Grassy Woodlands Of The Northern Tablelands, Nsw Australia, Chris R. Chilcott, N. Reid, R. D. B. Whalley

IGC Proceedings (1977-2023)

Limited information on the initial effects of clearing and thinning on herbaceous vegetation of grassy temperate eucalyptus forests exists. The aim of this investigation is to study the initial changes in species composition following clearing and thinning. A deforestation experiment was established where clearing, thinning of 50% of canopy cover and control treatments were established. In the open-forests, patterns in herbaceous species composition were strongly influenced by the presence of trees, with weeping wheat grass (Microlaena stipoides) dominant, whereas wiregrass (Aristida ramosa) dominated interspaces and canopy gaps. Immediately following clearing, significant changes in the herbaceous species …

The Influence Of Large Animal Diversity In Grazed Ecosystems, M. G. Murray, D. R. Baird

IGC Proceedings (1977-2023)

Field observations in the Serengeti National Park, Tanzania have revealed several modes of grazing system, including migration, sustained-yield grazing and grazing succession which contribute on the one hand to ecological separation of herbivores by habitat choice, but on the other hand to positive association of species on wet season pastures known as hot spots. Drawing from results of experimental field studies, we consider what is known about resource competition and facilitation, the two key ecological processes underlying these grazing systems, and specify the shape of the relationship between species richness and pasture height that is predicted depending on which process …

Grassland Use And Plant Diversity In Grazed Ecosystems, V. A. Deregibus, E. J. Jacobo, O. E. Ansin

IGC Proceedings (1977-2023)

Earth biomes are being deconstructed, through unprecedented rates of species disappearance or invasion (McCann 2000). This, added to the threat of global environmental change and changes in values of a developed society, caused that biodiversity became a topic that has captured the attention of the public as well as the scientific community. Such concern on the importance of biodiversity is based in four basic reasons clearly described by West (1993): (i) morality, that aims for the protection of species; (ii) aesthetics, as people desire to see and appreciate the living parts of nature; (iii) economics and, (iv) the array …

Vegetation Changes In Southeast Australian Temperate Grasslands, D. L. Garden, T. P. Bolger Dec 2021

Vegetation Changes In Southeast Australian Temperate Grasslands, D. L. Garden, T. P. Bolger

IGC Proceedings (1977-2023)

In temperate areas of southeast Australia, the combined effects of tree clearing, grazing, application of fertilizer and the introduction of exotic species have modified the original grasslands. This paper describes these changes and attempts to explain them in terms of ecological principles derived from North American grasslands. Stability of the original grasslands appears to have been due to the lack of disturbance and the slow rates of nitrogen (N) cycling within them. Increased N cycling after disturbance has allowed invasion of species better adapted to higher N status, particularly exotic annual grasses and weeds. The present composition of grasslands, in …

The Effects Of Grazing Management And Fertilization On Grassland Diversity And Productivity, Warren Mcg. King, David R. Kemp Dec 2021

The Effects Of Grazing Management And Fertilization On Grassland Diversity And Productivity, Warren Mcg. King, David R. Kemp

IGC Proceedings (1977-2023)

The effects of management practices on plant species diversity and productivity within a naturalised grassland was studied as part of a large-scale experiment designed to investigate issues of sustainability in temperate Australia. Fertiliser increased the production but reduced the diversity of the sward. The main decline was in exotic weed species. Strategic grazing resulted in a small increase in pasture diversity but a reduction in productivity. There was a consistent decline in diversity as productivity increased, across all treatments.

Coal Geology & Exploration

In order to reveal the characteristics of nano-scale pores in coals with different metamorphic degrees, the small-angle X-ray scattering method (SAXS) is used to obtain the porosity, pore size distribution, specific surface area and fractal dimension of 15 samples whose vitrinite reflectance Rmax is 0.31%-6.24%, and the low temperature CO2 and N2 adsorption DFT model results are used to verify the pore size distribution. The results show: during coalification process, when Rmax is < 0.5%, the porosity and the specific surface area of coal increase with the increase of metamorphic degree, the micropores(< 2 nm) content increases seldomly, the mesoporous(2-50 nm) and microporous(50-100 nm) content increase greatly, and the surface of coal is gradually smooth. When Rmax=0.5%-1.4%, the porosity and the specific surface area decrease, and each type of pore content is reduced, and the surface of …
