Biological soil crust and vascular plant interactions in Western Myall ( Acacia papyrocarpa ) open woodland in South Australia

Mossbauer Spectra of Soil Kaolins from South-western Australia

-Six well-characterized soil kaolins from widely separated sites in south-western Australia and four reference kaolins were studied by 57Fe M6ssbauer spectroscopy at room temperature after removal of non-structurally-bound iron with dithionite-citrate-bicarbonate solution. The soil kaolins and one of the reference kaolins were also studied at temperatures near 16 K. The soil kaolins were remark...

Do biotic interactions modulate ecosystem functioning along stress gradients? Insights from semi-arid plant and biological soil crust communities.

Climate change will exacerbate the degree of abiotic stress experienced by semi-arid ecosystems. While abiotic stress profoundly affects biotic interactions, their potential role as modulators of ecosystem responses to climate change is largely unknown. Using plants and biological soil crusts, we tested the relative importance of facilitative-competitive interactions and other community attribu...

An Archaeobotanical Perspective on Environment, Plant Use, Agriculture, and Interregional Contact in South and Western Iran

Plant remains from archaeological sites reflect many aspects of the relationship between people, plants, and the environmentin which they lived. Plant macroremains—seeds and wood that are visible without a microscope—can address a widerange of questions. The most basic include what crops were grown? What was used for fuel? Do any of the plants comefrom distant lands? Examples from fourth and th...

Changes in the soil micro-topography of two coastal hiking trails in south-western Australia

Two coastal walk trails in south-western Australia were subjected to a specific soil erosion and microtopography assessment between 2004–2007. A point intercept (PIN) frame was used to evaluate change over time to the trail profile. Estimates of soil loss are quantified and discussed in relation to previous historical use and a lack of appropriate management intervention. The results show that ...
