Abstract Diplazium esculentum is a herbaceous fern native to Asia. It has been introduced into a number of countries in Africa, Oceania and North America as an ornamental and as a food source. As it produces a large number of spores it can easily escape cultivation and rapidly spread into new areas. The species is reported as having escaped cultivation and become invasive in Hawaii, USA, New Zealand and Australia. In Hawaii, D. esculentum grows abundantly in wet valleys and in sheltered moist areas at dry sites. It is also a frequent volunteer in gardens. In New Zealand it has escaped from cultivation, spreading rapidly and aggressively in riverbanks at an average rate of spread of 1 m per year. In Australia the species is widely cultivated for food and as an ornamental, naturalising in swampy areas of Queensland. Its impacts on other habitats or species are unknown.

Mode A

Grid-independent rate of spread results from a physics-based simulation are presented. Previously, such a numerical benchmark has been elusive owing to computational restrictions. The grid-converged results are used to systematically construct correlations between the rate of spread (RoS) and both wind speed and grass height, separately. The RoS obtained from the physics-based model is found to be linear with wind speed in the parameter range considered. When wind speed is varied, the physics-based model predicts faster RoS than the Mk III and V (McArthur) models (Noble et al. 1980) but slower than the CSIRO model (Cheney et al. 1998). When the grass height is varied keeping the bulk density constant, the fire front changes from a boundary layer flame mode to plume flame mode as the grass height increases. Once the fires are in plume mode, a higher grass height results in a larger heat release rate of the fire but a slower RoS.

Scalable Synthesis

Mathuralure (1) is the major sex pheromone component of the pink gypsy moth Lymantria mathura, a potentially devastating invasive species to North America. To support population monitoring of this moth, a gram-scale synthesis of (–)-mathuralure (1) was developed. This process relies on coupling an alkynyl lithium species with a chloroepoxide and provides access to the natural product in a 10% yield over 10 steps.
