Between concepts and experiences: understandings of climate change in southern Ecuador.

For decades, researchers have worried about people's understanding of climate change. Although this understanding varies by cultural context, most studies so far have taken place in industrialised countries. Few studies have explored understandings of climate change in the global South. Through standardised questionnaires and semi-structured interviews conducted in southern Ecuador, this article explores differences between urban and rural dwellers and compares these with farmers' understandings of the causes, consequences and risks. We found urban and rural dwellers hold a similar understanding to that found in other nations, but articulated in ways that reflect their particular realities. Despite reporting firsthand experience of the agricultural effects of climate change, when prompted, farmers do not link climate change to their own experience. It is thus important to go beyond judging knowledge as correct or incorrect, and instead, incorporate local realities in the climate narrative.

Pilot Testing of a Sampling Methodology for Assessing Seed Attachment Propensity and Transport Rate in a Soil Matrix Carried on Boot Soles and Bike Tires.

Land managers of natural areas are under pressure to balance demands for increased recreation access with protection of the natural resource. Unintended dispersal of seeds by visitors to natural areas has high potential for weedy plant invasions, with initial seed attachment an important step in the dispersal process. Although walking and mountain biking are popular nature-based recreation activities, there are few studies quantifying propensity for seed attachment and transport rate on boot soles and none for bike tires. Attachment and transport rate can potentially be affected by a wide range of factors for which field testing can be time-consuming and expensive. We pilot tested a sampling methodology for measuring seed attachment and transport rate in a soil matrix carried on boot soles and bike tires traversing a known quantity and density of a seed analog (beads) over different distances and soil conditions. We found % attachment rate on boot soles was much lower overall than previously reported, but that boot soles had a higher propensity for seed attachment than bike tires in almost all conditions. We believe our methodology offers a cost-effective option for researchers seeking to manipulate and test effects of different influencing factors on these two dispersal vectors.
