- 摘要：
- Small farms and ranches are extremely important to local economies and food systems. Yet, small farms and ranches are known to struggle financially. A review of the literature and this research project revealed agritourism is a promising practice that can improve the viability and financial stability of small farms and ranches. Five farmers were interviewed in a qualitative study that used a modified gap analysis to reveal the knowledge, motivation, and organizational (KMO) influences impacting agritourism participation. The findings are summarized with recommendations to further improve this promising practice, as well as ideas for future research and a plan to implement and evaluate an agritourism program that could change how farmers approach this promising practice.

Data from: What can interaction webs tell us about species roles?

- 摘要：
- The group model is a useful tool to understand broad-scale patterns of interaction in a network, but it has previously been limited in use to food webs, which contain only predator-prey interactions. Natural populations interact with each other in a variety of ways and, although most published ecological networks only include information about a single interaction type (e.g., feeding, pollination), ecologists are beginning to consider networks which combine multiple interaction types. Here we extend the group model to signed directed networks such as ecological interaction webs. As a specific application of this method, we examine the effects of including or excluding specific interaction types on our understanding of species roles in ecological networks. We consider all three currently available interaction webs, two of which are extended plant-mutualist networks with herbivores and parasitoids added, and one of which is an extended intertidal food web with interactions of all possible sign structures (+/+, -/0, etc.). Species in the extended food web grouped similarly with all interactions, only trophic links, and only nontrophic links. However, removing mutualism or herbivory had a much larger effect in the extended plant-pollinator webs. Species removal even affected groups that were not directly connected to those that were removed, as we found by excluding a small number of parasitoids. These results suggest that including additional species in the network provides far more information than additional interactions for this aspect of network structure. Our methods provide a useful framework for simplifying networks to their essential structure, allowing us to identify generalities in network structure and better understand the roles species play in their communities.
