Microbial communities that degrade natural polysaccharides are thought to have a hierarchical organization and one-way positive interactions from higher to lower trophic levels. Daniels et al. have recently shown that reciprocal interactions between trophic levels can occur and that these interactions change over the duration of a batch culture.

The growth of microbial populations in nature is dynamic, as the cellular physiology and environment of these populations change. Understanding the growth dynamics of these populations has wide-ranging consequences for their ecology and evolution; it may also be critical for clinical and environmental applications in which we need to promote or inhibit microbial growth. Here we review the [...]

Humans have been giving a selective advantage to antibiotic-resistant bacteria worldwide by inundating the environment with antimicrobials for about one century. As a result, the efficacy of antibiotics has been impaired. Antibiotic resistance is a public health problem, responsible for increases in mortality and extended stays at hospitals. Hospitals and other clinical settings have implemented [...]

Humans have inundated the environment worldwide with antimicrobials for about one century, giving selective advantage to antibiotic-resistant bacteria. Therefore, antibiotic resistance has become a public health problem responsible for increased mortality, and extended hospital stays because the efficacy of antibiotics has diminished. Hospitals and other clinical settings have implemented [...]

Studies of viral adaptation have focused on the selective pressures imposed by hosts. However, there is increasing evidence that interactions between viruses, cells, and other mobile genetic elements (MGEs) are determinant to the success of infections. These interactions are often associated with antagonism and competition, but sometimes involve cooperation or parasitism. They involve mechanism [...]

Movement is critical for the fitness of organisms, both large and small. It dictates how individuals acquire resources, evade predators, exchange genetic material, and respond to stressful environments. Movement also influences ecological and evolutionary dynamics at scales beyond the individual organism. However, the links between individual motility and the processes that generate and maintain [...]

The growing threat of vector-borne diseases, highlighted by recent epidemics, has prompted increased focus on the fundamental biology of vector-virus interactions. To this end, experiments are often the most reliable way to measure vector competence (the potential for arthropod vectors to transmit certain pathogens). Data from these experiments are critical to understand outbreak risk, but – [...]

Inter-individual differences in gut microbiota composition are hypothesized to generate variation in host fitness – a premise for the evolution of host-gut microbe symbioses. However, recent evidence suggests that gut microbial communities are highly dynamic, challenging the notion that individuals harbour unique and stable gut microbial phenotypes. Leveraging a long-term dataset of wild [...]

Society is confronted by interconnected threats to ecological sustainability. Among these is the devastation of forests by destructive non-native pathogens and insects introduced through global trade, leading to the loss of critical ecosystem services and a global forest health crisis. We argue that the forest health crisis is a public good social dilemma and propose a response framework that [...]

The ability to form biofilms is a functional trait shared by many bacterial species. Biofilms provide bacteria a sheltered environment where the nutrients and oxygen gradients create a heterogeneous matrix and promote cells to differentiate their metabolism and functions according to the position they occupy inside the matrix. Species of the Microcystis genus are among the most common [...]

Mycoplasma bovis is an economically important bacterial pathogen of cattle and bison that most commonly causes pneumonia, polyarthritis and mastitis. M. bovis is prevalent in cattle and commercial bison; however, infections in other species are rare. In early 2019, we identified M. bovis in free-ranging pronghorn (Antilocapra americana) in northeastern Wyoming, USA. Here we report on additional [...]

Horizontal gene transfer (HGT) drives microbial adaptation but is often under the control of mobile genetic elements (MGEs) whose interests are not necessarily aligned with those of their hosts. In general, transfer is costly to the donor cell while potentially beneficial to the recipients. The diversity and plasticity of cell-MGEs interactions, and those among MGEs, results in complex [...]

Bacterial organisms like surfaces. Water and soil contain a multiplicity of particulated material where bacterial populations and communities might attach. Microbiotic particles refers to any type of small particles (less than 2 mm) where bacteria (and other microbes) might attach, resulting in medium- long-term colonization. In this work, the interactions of bacterial organisms with microbiotic [...]

Beneficial microorganisms shape the evolutionary trajectories of their hosts, facilitating or constraining the colonization of new ecological niches. One convincing example entails the responses of insect-microbe associations to rising temperatures. Indeed, the insect resilience to stressful high temperatures depends on the genetic identity of the obligate symbiont and the presence of heat [...]
