“…The annual grass, Panicum miliaceum L. (Proso millet), has produced relatively recent biotypes better adapted to spread by combine harvesters (Bough et al. , 1986; McCanny & Cavers, 1988; McCanny et al. , 1988).…”

Climate change and weed adaptation: can evolution of invasive plants lead to greater range expansion than forecasted?

Invasive plants are frequently viewed as harbingers of climate change owing to their potential to cause economic and ecological damage in the process of expanding their ranges. Models are being developed to help predict the range expansion of these plants, based on known tolerance ranges. Success of weeds has often been attributed to an Ôall-purpose genotypeÕ, implying a high level of phenotypic plasticity. However, recent work has shown that many species are capable of relatively rapid genetic change as well, enhancing their ability to invade new areas in response to anthropogenic ecosystem modification. We thus predict that range expansion by many invasive species will exceed that predicted by modelling approaches that do not consider potential evolutionary change. We highlight a number of cases where weeds have expanded their latitudinal ranges or are predicted to do so in response to climatic selection pressures. We also list ten traits as likely targets for natural selection under climate change. The lag phase commonly observed for invasive species may frequently be a result of the time needed for the invader to evolve to fit the new habitat. During this present period of climate change, many invasive plant populations are likely to be in the process of developing adaptations that could lead to exponential population growth in the near future. Thus, assessment of the risk of invasive species owing to changing climate must incorporate evolutionary potential.

“…Combine harvesting has been analysed as a cause of dispersal within (Ballaré et al. , 1987; McCanny & Cavers, 1988) and among fields (McCanny et al. , 1988), but has rarely been related to spatial variability of weed populations (Dieleman & Mortensen, 1999; Colbach et al.…”

Spatial distribution of Lolium rigidum seedlings following seed dispersal by combine harvesters

et al. 2004

This paper considers the relationships between the dispersal of seeds and the distribution pattern of an annual weed. A comparative study of seed dispersal by combine harvesters, with and without a straw chopper attached, was established using Lolium rigidum, a common weed in Mediterranean cereal crops. Seed dispersal distance was quantified and the relationships between dispersal and fine-scale seedling distribution evaluated. Primary dispersal of L. rigidum seeds occurs in a very limited space around the parent plants, but the density of seed is low because most seeds do not fall from spikes spontaneously. In contrast, many seeds are spread by combine harvesters. In this study the maximum dispersal exceeded 18 m from established stands in cereal fields, although the modal distance was close to the origin. In addition, the action of the combine harvesters tended to accumulate L. rigidum seeds predominantly under the straw swath, with some lateral movement. This action could explain the fine-scale banded pattern of L. rigidum in cereal fields. Although the treatment of straw by the standard and straw chopper combines differed, the resultant seed distribution showed few differences.
