In response to environmental, economic, and social challenges, the living labs approach innovation is receiving increasing attention within agricultural sector. this paper, we propose a set of defining characteristics for an emerging type lab intended increase sustainability resilience agriculture agri-food systems: “agroecosystem lab”. Drawing on first-hand knowledge case studies large initiat...

The vision of the Long Term Agroecosystem Research (LTAR) network is to enable multi-decadal, trans-disciplinary, and cross-location science ensure long-term sustainability U.S. agriculture. LTAR's primary goals are to: (1) Intensify agricultural productivity, (2) Improve ecosystem services related production, (3) rural prosperity. LTAR includes 18 locations (sites). It 10 existing hydrologic o...

In tropical ecosystems, ants represent a substantial portion of the animal biomass and contribute to various ecosystem services, including pest regulation and pollination. Dominant ant species are known to determine the structure of ant communities by interfering in the foraging of other ant species. Using bait and pitfall trapping experiments, we performed a pattern analysis at a fine spatial ...

uring the 1980s, crisphead lettuce, butterhead lettuce, and spinach crops in western Oregon (Fig. 1) became increasingly damaged by beet western yellows luteovirus (BWYV) (5,8) infection (15), a previously insignificant problem in this area. Utilizing double antibody sandwich enzyme-linked immunosorbent assay (DASELISA) methodology (2), we identified potential BWYV inoculum sources in vicinitie...

This paper combines theory from ecology and anthropology to investigate variation in the territory sizes of subsistence oriented agricultural societies. The results indicate that population and the dependence of individuals within a society on "wild" foods partly determine the territory sizes of agricultural societies. In contrast, the productivity of an agroecosystem is not an important determ...

Trophic cascades exist in numerous terrestrial systems, including many systems with ants as the top predator. Many studies show how behavioral modifications of herbivores are especially important in mediating species interactions and trophic cascades. Although most studies of trophic cascades focus on predator-herbivore-plant links, the trophic cascades concept could be applied to almost any le...
