Many Gram-negative bacteria use a type III secretion system (T3SS) to establish associations with their hosts. The T3SS is a conduit for direct injection of type-III effector proteins into host cells, where they manipulate the host for the benefit of the infecting bacterium. For plant-associated pathogens, the variations in number...
Questions: Mountain systems have high abiotic heterogeneity over local spatial scales, offering natural experiments for examining plant species invasions. We ask whether functional groupings explain non-native species spread into native vegetation and up elevation gradients.We examine whether non-native species distribution patterns are related to environmental variables after controlling for elevation...
Global environmental change is causing local extinctions of species. When species depend on one another, as in the mutualistic relationship between plants and pollinators, loss of one interaction partner may cause cascading effects within the community – such as additional extinctions and reduced pollination services. Network theory provides a way...
This dataset includes species richness of native plants, pollinators and birds as well as 13 proxies for ecosystem services representing timber production, culturally-valued plants and animals, and regulating services tied to forest productivity. The data were collected from an experiment conducted in the Oregon Coast Range USA that sought to...

Biological invasions threaten native biodiversity, alter ecosystem function, and are a major cause of economic losses across the planet. The most impactful invaders alter disturbance regimes and initiate state shifts to outside the historical range of variability of the ecosystem. Concern for ecological and economic losses has prompted a rapid...
The effect of three different weed management strategies, non-weeding, hand weeding, and weed mat, were examined on physicochemical, sugar profile, and antioxidant properties of two cultivars of blackberry (Rubus spp), ’Marion’ and ’Black Diamond’ harvested at three time intervals during the 2012 season. Sensory analysis on flavor intensity of six...
Unlike most investor-owned enterprises, cooperatives often have freedom to choose among a variety of firm objectives. Using 2002–2008 plantand province-level data, we ask in the present article which of several alternative maximands a Korean cooperative rice processing firm pursues. In contrast to earlier studies, farmer-member supply functions are incorporated into...
