Biogeography of plant‐associated fungal symbionts in mountain ecosystems: A meta‐analysis

Meta-analysis revealed broad biogeographic patterns in plant-fungal symbiont abundance, diversity and composition that inform predictions of future distributions, suggesting that species turnover contributes more to elevational gradients in fungal symbionts than does variation in abundance or richness.

A mutualistic endophyte alters the niche dimensions of its host plant

A symbiotic relationship is identified as a potential mechanism facilitating the coexistence of two species, suggesting that symbiont effects on host niche may have community-level consequences.

Plant Identity Influences Foliar Fungal Symbionts More Than Elevation in the Colorado Rocky Mountains

It is suggested that across the ~ 300 m elevation range that the authors sampled, foliar fungal symbionts may indirectly experience climate change by tracking the shifting distributions of plant hosts rather than tracking climate directly.

Does a foliar endophyte improve plant fitness under flooding?

The novel hypothesis that endophyte symbiosis promotes host fitness under flooded conditions, contributing to niche differentiation between the two bluegrass species is investigated, demonstrating an overall benefit of fungal symbiosis in this system.

Context‐dependent biotic interactions control plant abundance across altitudinal environmental gradients

Altitudinal gradients fail to predict fungal symbiont responses to warming.

It is indicated that altitude does not always serve as an adequate proxy for warming effects on fungal symbionts of plants, and predicting climate effects on symbioses will require tracking both host and symbiont identities.

Predicting changes in bee assemblages following state transitions at North American dryland ecotones

Comparing bee assemblages and their seasonality among sites at the Sevilleta National Wildlife Refuge that represent three dryland ecosystem types (and two ecotones) of the southwestern U.S. found strong seasonal bee species turnover, suggesting that bee phenological shifts may accompany state transitions.

Grass species identity shapes communities of root and leaf fungi more than elevation

Fungal symbionts can buffer plants from environmental extremes and may affect host capacities to acclimate, adapt, or redistribute under environmental change; however, the distributions of fungal…

Life-history traits predict responses of wild bees to climate variation

Life-history traits, which are physical traits or behaviours that affect growth, survivorship and reproduction, could play an important role in how well organisms respond to environmental change. By…

Plant Identity Influences Foliar Fungal Symbionts More Than Elevation in the Colorado Rocky Mountains

Despite colonizing nearly every plant on Earth, foliar fungal symbionts have received little attention in studies on the biogeography of host-associated microbes. Evidence from regional scale studies…
