Phototaxis and courtship behavioral preferences reflect strong correlation with differences in olfactory and visual nervous system investment across five monophyletic Drosophila species, and could help explain their speciation events.
Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
Genome-wide chromatin mapping during bacterial-fungal cocultivation identifies the Myb-like transcription factor BasR as the major regulatory node of bacteria-triggered production of fungal secondary metabolites.
Experiments and mathematical modelling show that rare nitrogen fixing symbionts invade a population dominated by non-fixing bacteria across plant generations, above a threshold of a combination of ecological factors.
The genetic make-up of dominating MDR-TB clades in Central Asia is shaped by programmatic and socio-economic changes that led to fixation of resistance and bacterial fitness related mutations in the Soviet era.
