Predatory Interactions Between Myxobacteria and Their Prey
The myxobacteria are an order of abundant and virtually ubiquitous soil-dwelling Deltaproteobacteria. They initially attracted scientific attention in the nineteenth century for their ability to…
Deciphering the hunting strategy of a bacterial wolfpack.
- BiologyFEMS microbiology reviews
The multicellular structures formed during contact with prey, and the molecular mechanisms utilized by M. xanthus to detect and destroy prey cells are examined to examine the understanding of the predatory life cycle of M. Xanthus.
Hunters or gardeners? Linking community structure and function of trap-associated microbes to the nutrient acquisition strategy of a carnivorous plant
- Environmental SciencebioRxiv
Assessment of the trap-associated microbial community structure, diversity, function, as well as the nutrient recycling potential of bacterivory gained insight into the nutrient acquisition strategies of the Utricularia hosts concluded that trap ecophysiological function is in many aspects highly analogous to that of the herbivore gut.
Decomposing Predation: Testing for Parameters that Correlate with Predatory Performance by a Social Bacterium
- Environmental ScienceMicrobial Ecology
Five predation-related parameters were quantified during M. xanthus growth on nine phylogenetically diverse bacterial prey species to highlight the importance of examining multiple parameters for thoroughly understanding the population biology of microbial predation.
ORIGINS OF ALTRUISM DIVERSITY I: THE DIVERSE ECOLOGICAL ROLES OF ALTRUISTIC STRATEGIES AND THEIR EVOLUTIONARY RESPONSES TO LOCAL COMPETITION
- BiologyEvolution; international journal of organic evolution
The results contribute to explaining the observed natural diversity of altruistic strategies, reveal the necessary connection between the evolution and the ecology of sociality, and correct the widespread but inaccurate view that local competition uniformly impedes the evolution of altruism.
Relative Contributions of Halobacteriovorax and Bacteriophage to Bacterial Cell Death under Various Environmental Conditions
- Environmental Science, BiologymBio
Findings suggest that along with bacteriophage and protists, Halobacteriovorax has the potential to have a prominent role in bacterial mortality and cycling of nutrients, two vital ecologic functions.
Cooperation increases robustness to ecological disturbance in microbial cross-feeding networks
- Environmental SciencebioRxiv
This work finds the opposite pattern: natural selection in the form of ecological disturbance favors both specific network topologies and cooperative cross-feeding among community members, establishing environmental selection as a key driver shaping the architecture of microbial interaction networks.
Cooperation increases robustness to ecological disturbance in microbial cross-feeding networks.
- Environmental ScienceEcology letters
Microorganisms mainly exist within complex networks of ecological interactions. Given that the growth and survival of community members frequently depend on an obligate exchange of essential…
Hunters or farmers? Microbiome characteristics help elucidate the diet composition in an aquatic carnivorous plant
- Medicine, BiologyMicrobiome
It is concluded that Utricularia traps can, in terms of their ecophysiological function, be compared to microbial cultivators or farms, which center around complex microbial consortia acting synergistically to convert complex organic matter into a source of utilizable nutrients for the plants.
Extraordinary Multi-Organismal Interactions Involving Bacteriophages, Bacteria, Fungi, and Rotifers: Quadruple Microbial Trophic Network in Water Droplets
- Environmental Science, BiologyInternational journal of molecular sciences
The involvement of bacteriophages in rotifer hunting was demonstrated based on molecular analyses and was discussed, and the described case seems to be an extraordinary quadruple microbiological puzzle that has not been described and is still far from being understood.
