Resilience in Agriculture through Crop Diversification: Adaptive Management for Environmental Change (2011, background): “…plant species richness and composition were manipulated, the pathogen load was almost three times greater in the monoculture plots, where host abundance was at a maximum, than in the polyculture plots planted with 24 grassland species (an approximation of natural diversity; Mitchell et al. 2002).”
Effects of elevated CO2, nitrogen deposition, and decreased species diversity on foliar fungal plant disease (2003, methodology): “…of the disease severity of each constituent species, with disease severity of each species weighted by the biomass of that species, following Mitchell et al. (2002): l P n i1 S i C i P n i1 C i 1 where l is pathogen load, S i is disease severity of the ith species, C i is biomass of…”
Trophic control of grassland production and biomass by pathogens (2003, methodology): “However, recent studies indicate that components of environmental change such as decreased plant species diversity (Mitchell et al. 2002; Mitchell et al. in press), nitrogen deposition (Strengbom et al. 2002; Mitchell et al. in press) and climate warming (Harvell et al. 2002) can increase foliar…”
Biodiversity-Ecosystem Function Research: Is It Relevant to Conservation? (2005, background): “In essence, specialized enemies create frequency-dependent selection among species or genotypes (e.g., Mitchell et al. 2002).”
Biomass production, symbiotic nitrogen fixation and inorganic N use in dual and tri-component annual intercrops (2005, background): “…other things profoundly affect soil fertility (Hooper, 1998; Russell, 2002; Swift and Anderson, 1993), increase nutrient and water-use efficiency and resistance to crop diseases (Mitchell et al., 2002), thereby providing stability to the cropping system (Swift and Anderson, 1993; Trenbath, 1999).”
Impacts of biodiversity on the emergence and transmission of infectious diseases (2010, background): “For plants, seeding experimental fields with plant species that are not hosts for fungal pathogens decreased threefold the pathogen load of species that are hosts, apparently by reducing host density through competition 66 .”
Mechanisms responsible for the positive diversity–productivity relationship in Minnesota grasslands (2004, methodology): “This strong relationship between overyielding and foliar pathogen disease severity (opposite in direction than expected) may be explained by host-specific foliar pathogens that respond to the density, not frequency of their hosts (Mitchell et al. 2002).”
Increasing forest loss worldwide from invasive pests requires new trade regulations (2014, background): “Does the diversity of tree species play a protective role? It has been hypothesized that species-rich forests should have fewer pests because effective host density is lower (Mitchell et al. 2002) and because of interference: propagules can be “lost” by landing on non-hosts (Burdon and Chilvers 1982”
Effects of Host Diversity on Infectious Disease (2012, background): “Monocultures of genetically similar or identical plants are notoriously susceptible to disease spread, whereas genetic mixtures of the same plants are more resistant (Elton 1958, Mundt 2002).”
Effects of species diversity on disease risk. (2006, background): “For example, Knops et al. (1999) and Mitchell et al. (2002, 2003) investigated the effects of plant species richness on the prevalence of foliar fungal diseases, each specific to a particular host plant species.”
