Abiotic Influences on Free-Living Microbial Communities in Hydrothermal Vent Ecosystems
(2016-05-18)
Hydrothermal vent ecosystems are defined by steep thermal and chemical gradients. Chemosynthetic microorganisms are the primary producers in these systems, utilizing the available chemical energy to support substantial ...
Selection for Antibiotic Production
(2016-05-18)
Antibiotic-producing microorganisms can gain a selective advantage by inhibiting nearby competing species. However, despite their genetic potential, natural isolates often make only small amounts of antibiotics and laboratory ...
Microbiome-Targeted Interventions for Colitis-Associated Bacteria
(2016-05-06)
Complex interactions between mammalian hosts and their gut microbes have evolved over many millennia and have established a sophisticated communication system that is essential for symbiosis and mutualism. Perturbations ...
Mode and Fidelity of Bacterial Symbiont Transmission and Its Impact on Symbiont Genome Evolution
(2016-05-18)
Mutualistic symbioses have enabled the colonization of novel habitats and niches in a large array of eukaryotic and bacterial taxa. Reliable mechanisms of symbiont transmission between host generations are necessary to ...
Competition and Coexistence in Yeast Experimental Evolution
(2016-05-19)
Natural selection gives rise to biodiversity by purging the less-fit among variants that are too similar (a principle known as character displacement), but to predict how fit or different an organism needs to be to survive ...
Convergent Interactions Among Pitcher Plant Microcosms in North America and Southeast Asia
(2016-08-03)
Ecosystems are composed of diverse suites of organisms whose interactions are mediated by both the biotic and abiotic constraints of their environments. The complexity of ecosystems makes them both resilient and difficult ...
