Biogeochemical processes rendered by the aquatic microbiome could influence the development of cyanobacterial harmful algal blooms (cHABs), but those biotic factors are poorly understood and rarely considered. We focused on the link between microbial functions, community composition and environmental gradients along the Thames River–Lake St. Clair–Detroit River–Lake Erie corridor across different seasons. We measured the abund...

The occurrence of facultative endosymbionts has been studied in many commercially important crop pest aphids, but their occurrence and effects in non‐commercial aphid species in natural populations have received less attention. We screened 437 aphid samples belonging to 106 aphid species for the eight most common facultative aphid endosymbionts. We found one or more facultative endosymbionts in 53% (56 of 106) of the species i...
