We document a facultative Bartonella-like Rhizobiales bacterium in the giant tropical ant, Paraponera clavata. In a lowland tropical rainforest in Costa Rica, 59 colonies were assayed for the prevalence of the Bartonella-like bacterium (BLB), 14 of which were positive. We addressed three questions: First, how does the prevalence of BLB within colonies vary with environmental conditions? Second, how does diet affect the prevalence of BLB in P. clavata? Third, how does the distribution of BLB among colonies reflect ambient differences in food resources and foraging habits? A variety of environmental variables that may be predictive of the presence of BLB …

The deep sea is a unique and extreme environment characterized by low concentrations of highly recalcitrant carbon. As a consequence, large organic inputs have potential to cause significant perturbation. To assess the impact of organic enrichment on deep sea microbial communities, we investigated bacterial diversity in sediments underlying two whale falls at 1820 and 2893 m depth in Monterey Canyon, as compared with surrounding reference sediment 10-20 m away. Bacteroidetes, Epsilonproteobacteria and Firmicutes were recovered primarily from whale fall-associated sediments, while Gammaproteobacteria and Planctomycetes were found primarily within reference sediments. Abundant Deltaproteobacteria were recovered from both sediment types, but the …
