Última Estimating the public benefits of mitigating damages caused by invasive plant species in a subsistence economy AgEcon Rai, Rajesh Kumar; Scarborough, Helen. This paper presents analysis of a choice experiment (CE) designed to estimate willingness-topay (WTP) to mitigate damages caused by invasive plant species (IPS) in a rural community of Nepal. In order to address the cash constraints problem in a subsistence economy, two payment attributes, labor contribution and membership fee, were included in the choice sets. The results reveal that rural farmers have significant WTP for forest management activities, in terms of both cash and labor contributions. The results also suggest that rural farmers value their time in this context at a different rate to the current wage rate.

Ano: 2012 URL: http://purl.umn.edu/124421 Allelopathic suppression by Conyza canadensis depends on the interaction between latitude and the degree of the plant’s invasion Acta Botanica Wang,Congyan; Jiang,Kun; Zhou,Jiawei; Liu,Jun. ABSTRACT Allelopathic suppression of the growth of co-occurring plant species in invaded ecosystems is an important factor in some plant invasions. This study uses leaf extracts of the invasive plant species Conyza canadensis to determine its allelopathic effects along a latitudinal gradient, and under different cover classes and degrees of invasion, on seed germination and growth of Lactuca sativa, a sensitive bioindicator of allelochemicals. The allelopathic effects of C. canadensis on seedling height, root length, seedling biomass, germination percentage, germination potential, germination index, germination rate index, and vigor index of L. sativa increased significantly with increasing latitude. A possible explanation is that the leaves of plants...
