Global distributions and plant associations of the ecologically diverse ascomycete order Helotiales

This study quantifies the specificity of Helotiales-plant associations using global occurrence data and phylogenetic analysis, revealing structured ecological relationships.

Environmental filtering and host identity collectively shape root-associated microbiomes of Ericaceae and ectomycorrhizal plants in fumarole fields

Few root-associated microbial operational taxonomic units (OTUs) in Japanese fumarole fields prefer both a habitat and a host; most specialize on one axis, and Hyaloscyphaceae preferences lack significant phylogenetic signal.

ELAplus: Fast and accurate analysis platform for energy landscape analysis facilitated by fine-tuning optimization algorithm.

ELAplus improves energy landscape analysis for ecological communities by enhancing computational efficiency and uncertainty assessment through optimized algorithms and bootstrap methods.

Response diversity can stabilize or destabilize community dynamics depending on the number of insensitive species

This paper shows response diversity can stabilize or destabilize communities depending on the proportion of insensitive species, highlighting the need for better metrics that distinguish species sensitivity from response variation.

Complexity-multistability relationships: How does species diversity shape the number of alternative stable states?

The paper develops a framework to quantify multistability in ecological communities and finds that competitive interactions increase the number of alternative stable states with higher species diversity.

Stochastic Forces in Microbial Community Assembly: Founding Community Size Governs Divergent Ecological Trajectories

This study quantifies how initial stochasticity in microbial community assembly affects ecological trajectories by varying founding community size and analyzing divergence in community dynamics.

High density invasion by the shrub Ardisia crenata in Florida, USA is associated with altered soil chemical properties and microbial communities

Do below-ground genotypes influence above-ground microbiomes of grafted tomato plants?

This study examines how rootstock genotypes influence phyllosphere microbiomes in grafted tomato plants, finding no overall difference but some taxa preferences.
