Recently we have demonstrated that grass and cut grass are important sources of volatile organic compound (VOC) emissions into the atmosphere. The production of these VOCs can be traced back to plant growth, maintenance and wound defence mechanisms. The gases emitted as part of these wound defence mechanisms are responsible for the smell of freshly cut grass, and are also highly photochemically...

In this study, perennial fast growth Napier grass fibers were used for pulp and papermaking. Chlorination and alkaline process were carried using sodium chlorite and sodium hydroxide respectively for pulp extraction from Napier grass. Detailed chemical composition of the Napier grass fibers and the extracted pulp was carried out and a comparison with other perennial grasses made. The extracted ...

Plants are the essential factors shaping soil microbial community (SMC) structure. When most studies focus on the difference in the SMC structure associated different plant species, the variation in the SMC structure associated with phylogenetically close species is less investigated. Legume (Fabaceae) and grass (Poaceae) are functionally important plant groups; however, their influences on the...

GeoPAT modules are written in ANSI C and are designed to work within the GRASS GIS 7 (GRASS Development Team, 2012) environment. Embedding GeoPAT in GRASS has a number of advantages: • GRASS is an open source software available for major computing platforms, • GRASS is especially well suited to work with large datasets, • incorporating a toolbox into an already existing, well-established enviro...

Cockatoo grass [Alloteropsis semialata (R.Br.) A. Hitchc.] is considered a keystone species in northern Australian ecosystems as it provides a food resource for many species, including several endangered vertebrates. This study examined both local and regional environmental factors influencing cockatoo grass distribution and abundance in the Wet Tropics of north Queensland, Australia. Local dis...

The efficiency of wet explosion applied as modified dilute acid pretreatment at previously identified reference conditions (150°C, 0.3% H(2)SO(4), 15 min) was investigated on lucerne, ryegrass, fescue grass, cocksfoot grass, rye fescue, forage grass, and wheat straw in order to identify their potential as feedstock for cellulosic bioethanol production. After pretreatment, cellulose recovery was...

Non-native plants are invading terrestrial ecosystems across the globe, yet little is known about how invasions impact carbon (C) cycling or how these impacts will be influenced by climate change. We quantified the effect of a non-native C4 grass invasion on soil C pools and fluxes in a Hawaiian tropical dry forest over 2 years in which annual precipitation was average (Year 1) and 60% higher t...
