Evolutionary Origins and Ecological Consequences of Endophyte Symbiosis with Grasses
Over the past 20 yr much has been learned about a unique symbiotic interaction between fungal endophytes and grasses. The fungi (Clavicipitaceae, Ascomycota) grow intercellularly and systemically inExpand

Soil pathogens and spatial patterns of seedling mortality in a temperate tree
The Janzen–Connell hypothesis proposes that host-specific, distance- and/or density-dependent predators and herbivores maintain high tree diversity in tropical forests. Negative feedback betweenExpand

Fungal Endophytes of Grasses: A Defensive Mutualism between Plants and Fungi
Many grasses are infected by systemic fungal endophytes (family Clavicipitaceae, Ascomycetes) that produce pysiologically active alkaloids in the tissues of their hosts. Infection makes grasses toxicExpand

GRASSROOTS ECOLOGY: PLANT-MICROBE-SOIL INTERACTIONS AS DRIVERS OF PLANT COMMUNITY STRUCTURE AND DYNAMICS
A growing body of research on plant-microbe interactions in soil is con- tributing to the development of a new, microbially based perspective on plant community ecology. Soil-dwelling microorganismsExpand

Fungal endophytes of grasses.
Mutualistic interactions between species are receiving increased attention from ecologists, although research lags far behind analogous work on competition or predator-prey interactions. MostExpand

Plant-soil biota interactions and spatial distribution of black cherry in its native and invasive ranges
One explanation for the higher abundance of invasive species in their non-native than native ranges is the escape from natural enemies. But there are few experimental studies comparing the parallelExpand

THE INCIDENCE AND EFFECTS OF HYBRIDIZATION BETWEEN CULTIVATED RICE AND ITS RELATED WEED RED RICE (ORYZA SATIVA L.)
The objectives of this study were (1) to determine if hybridization occurs naturally between cultivated rice and a closely related weed, red rice (both Oryza sativa L.) and (2) to determine theExpand

Microbial communities and interactions in the lone star tick, Amblyomma americanum
To quantify microbial composition and interactions, we identified prokaryotic communities in the lone star tick (Amblyomma americanum) based on 16S rRNA gene sequences and direct probing. The loneExpand

Conspecific Negative Density Dependence and Forest Diversity
Keep Your Distance Conspecific negative density dependence (CNDD), whereby the abundance of a species is limited by negative interactions between individuals of the same species, is thought to haveExpand

Herbivores cause a rapid increase in hereditary symbiosis and alter plant community composition.
Microbial symbioses are ubiquitous in nature. Hereditary symbionts warrant particular attention because of their direct effects on the evolutionary potential of their hosts. In plants, hereditaryExpand
