Targeted Viromes and Total Metagenomes Capture Distinct Components of Bee Gut Phage Communities

This study compares total metagenomes and viromes to assess phage communities in bee guts, finding that viromes enrich for phage in honey bees but total metagenomes capture more diverse phage in bumble bees.

Nontarget impacts of neonicotinoids on nectar-inhabiting microbes

The paper assesses the impact of neonicotinoids on nectar-inhabiting microbes using in vitro and nectar inoculation experiments, finding no significant effects at field-relevant concentrations within 24 hours.

Microbial Metamorphosis: Symbiotic bacteria and fungi proliferate during diapause and may enhance overwintering survival in a solitary bee

This study identifies a core microbiome in solitary bees during diapause, showing microbial proliferation and potential roles in pathogen protection and overwintering survival.

Dispersal overwhelms variation in host quality to shape nectar microbiome assembly.

The paper shows that dispersal has a greater impact than host quality on shaping nectar microbiome composition, as microbial density in open flowers correlates with pollen receipt.

Nectar compounds impact bacterial and fungal growth and shift community dynamics in a nectar analog

This study examines how non-sugar nectar compounds affect microbial growth and community dynamics in a nectar analog, revealing compound-specific and microbe-specific responses.

Thermal sensitivity and seasonal change in the gut microbiome of a desert ant, Cephalotes rohweri

The paper examines how temperature affects the gut microbiome of desert ants, finding that bacterial abundance and composition change with elevated temperatures in both field and lab settings.

Bee-associated fungi mediate effects of fungicides on bumble bees

This study investigates how fungicides affect bumble bees by altering their fungal associations, showing species-specific impacts on survival and microbiome composition.

Ecological dynamics of the almond floral microbiome in relation to crop management and pollination

This study examines how almond orchard management and pollination affect floral microbiome dynamics and pollinator behavior.

Fungi are more dispersal-limited than bacteria among flowers

The paper compares dispersal abilities of bacteria and fungi in flower-inhabiting microbial communities, finding bacteria disperse more readily via thrips and are more widespread.

Linked networks reveal dual roles of insect dispersal and species sorting for bacterial communities in flowers

The paper uses a multilevel network approach to show that visitor identity, not dispersal rate, is more important in structuring floral bacterial communities, while species sorting plays a key role in network structure.

Organic management promotes natural pest control through enhanced plant resistance to insects

This study shows organic farming increases plant resistance to pests through salicylic acid and soil microbiomes, reducing insect settling on tomatoes.

Microbial metabolites mediate bumble bee attraction and feeding

This study investigates how microbial metabolites in nectar influence bumble bee attraction and feeding behavior through volatile and non-volatile cues.

Plant species and soil type influence rhizosphere bacterial composition and seedling establishment on serpentine soils

The paper investigates how plant species and soil type affect rhizosphere bacterial communities and seedling establishment on serpentine soils.
