Evolutionary Origins and Ecological Consequences of Endophyte Symbiosis with Grasses
TLDR
Longitudinal studies suggest that the prevalence of seed‐transmitted endophytes can increase rapidly over time, and estimates of infection frequency have revealed variable levels of infection with especially high prevalence in the subfamily Pooideae.

Soil pathogens and spatial patterns of seedling mortality in a temperate tree
TLDR
This work shows that a soil pathogen leads to patterns of seedling mortality in a temperate tree (Prunus serotina) as predicted by the Janzen–Connell hypothesis, and suggests that similar ecological mechanisms operate in tropical and temperate forests.

Fungal Endophytes of Grasses: A Defensive Mutualism between Plants and Fungi
TLDR
Experiments demonstrate that plant growth and seed production can be increased by infection of systemic fungal endophytes in grasses, suggesting a defensive mutualism in which the fungi defend their hosts against herbivory, thereby defending their own resources.

Plant-soil biota interactions and spatial distribution of black cherry in its native and invasive ranges
TLDR
Evidence is presented showing that the invasion of black cherry into north-western Europe is facilitated by the soil community, which enhances the growth of its seedlings and improves the ability to predict and counteract plant invasions.

GRASSROOTS ECOLOGY: PLANT-MICROBE-SOIL INTERACTIONS AS DRIVERS OF PLANT COMMUNITY STRUCTURE AND DYNAMICS
TLDR
It is suggested that positive feedback between plants and soil microbes plays a central role in early successional communities, while negative feedback contributes both to species replacements and to diversification in later successional Communities.

Fungal endophytes of grasses.
TLDR
This research has shown clearly that plants benefit from a widespread mutualistic association between grasses, the authors' most familiar and important plant family, and endophytic fungi.

THE INCIDENCE AND EFFECTS OF HYBRIDIZATION BETWEEN CULTIVATED RICE AND ITS RELATED WEED RED RICE (ORYZA SATIVA L.)
TLDR
Overall, hybrids were vegetatively robust plants, demonstrating heterosis and expressing morphological characteristics of both parents, and produced more tillers than red rice.

Microbial communities and interactions in the lone star tick, Amblyomma americanum
TLDR
The findings indicate that microbial communities within lone star ticks are diverse, and suggest that direct probing for a wider range of prokaryotes and application of quantitative polymerase chain reaction (PCR) may provide further insights into microbial interactions within disease vectors.

Conspecific Negative Density Dependence and Forest Diversity
TLDR
It is found that most species experienced conspecific negative density dependence (CNDD), but there was little effect of heterospecific density, and abundant species exhibited weaker CNDD than rarer species, and species-rich regions exhibited stronger C NDD than species-poor regions.

Hybridization and the colonization of novel habitats by annual sunflowers
TLDR
Evidence is presented that the colonization of sand dune, desert floor, and salt marsh habitats by three hybrid sunflower species was made possible by selection on extreme or “transgressive” phenotypes generated by hybridization.
