Short Lag Times for Invasive Tropical Plants: Evidence from Experimental Plantings in Hawai'i

Short Lag Times for Invasive Tropical Plants: Evidence from Experimental Plantings in Hawai'i

BACKGROUND The lag time of an invasion is the delay between arrival of an introduced species and its successful spread in a new area. To date, most estimates of lag times for plants have been indirect or anecdotal, and these estimates suggest that plant invasions are often characterized by lag times of 50 years or more. No general estimates are available of lag times for tropical plant invasion...

Do Native and Invasive Labels Affect Consumer Willingness to Pay for Plants? Evidence from Experimental Auctions

Heterogeneous Consumer Preferences for Native and Invasive Plants: Evidence from Experimental Auctions

All stakeholders along the supply chain affect the dispersal of native and invasive horticultural plants. This is especially true for the consumers who determine how the plants are ultimately used. Therefore, consumer attitudes toward native and invasive plants cannot be ignored. This study used an experimental auction to explore market segmentation among consumers in terms of their preference ...

Protein from Tropical Plants

s of Workshop Papers Abstracts of Workshop Paperss of Workshop Papers TOBACCO LEAF PROTEIN Pilot-scale technology that extracts high-quality protein from young tobacco leaves has been developed. Soluble proteins extracted from tobacco plants might be added to foods as nutritional supplements or for functional properties (e.g., gelling, thickening). Although not fully tested, they might have a s...

Control of Invasive Species: Lessons from Miconia in Hawaii

The threat of invasive species stems from their ability to rapidly and irreversibly change ecosystems and degrade the value of ecosystem services. Optimal control of a pre-established exotic pest minimizes the costs of population reduction plus the residual damages from the remaining pest population. The shrubby tree, Miconia calvescens, is used to illustrate dynamic policy options for a forest...
