Macroecological patterns in experimental microbial communities

This study shows that macroecological patterns observed in natural microbial communities also emerge in controlled lab experiments and can be modeled using the Stochastic Logistic Model.

Investigating macroecological patterns in coarse-grained microbial communities using the stochastic logistic model of growth

This study uses the Stochastic Logistic Model to predict microbial biodiversity across taxonomic and phylogenetic scales, showing that ecological interactions are necessary to explain diversity patterns at different scales.

Metacommunity Structure Preserves Genome Diversity in the Presence of Gene-specific Selective Sweeps.

The paper shows that metacommunities can maintain genome diversity despite gene-specific selective sweeps through mathematical modeling and simulations.

The stochastic logistic model with correlated carrying capacities reproduces beta-diversity metrics of microbial

Ecological stochasticity and phage induction diversify bacterioplankton communities at the microscale

The paper investigates microscale microbial community dynamics on chitin particles, finding that stochastic processes and phage predation drive taxonomic and functional variability.

Universality of evolutionary trajectories under arbitrary competition dynamics

This paper develops a framework for evolutionary trajectories under arbitrary competition dynamics, showing universal properties across different systems.

Eco-evolutionary dynamics lead to functionally robust and redundant communities

The paper shows that microbial communities converge to a functional attractor determined by environmental conditions, with taxonomic diversity fluctuating while maintaining functional stability.

Heavy-tailed abundance distributions from stochastic Lotka-Volterra models

The paper shows how heavy-tailed abundance distributions in microbial communities emerge from stochastic Lotka-Volterra models with a global maximal capacity and specific parameter distributions.

A macroecological description of alternative stable states reproduces intra- and inter-host variability of gut microbiome

The paper analyzes gut microbiome time-series to show taxa have stationary fluctuations or quick changes indicating alternative stable states, and develops a model to predict community variability.

Threshold accumulation of a constitutive protein explains E. coli cell division behavior in nutrient upshifts.

The paper investigates E. coli cell division behavior during nutrient upshifts and finds that a constitutive protein accumulates to a threshold, triggering division and maintaining adder correlations.

ppGpp is a bacterial cell size regulator

This study shows ppGpp regulates bacterial cell size by controlling growth rate and division, leading to size homeostasis.

Laws of diversity and variation in microbial communities

The paper identifies three universal macroecological laws governing microbial community diversity and variation, showing they can be explained by environmental stochasticity.

Dissecting the control mechanisms for DNA replication and cell division in E. coli

This study re-evaluates existing models of DNA replication and cell division in E. coli, concluding that replication is not the sole bottleneck and proposing a dual-cycle mechanism.

Concurrent processes set E. coli cell division

The paper challenges the classic view that chromosome segregation limits cell division in E. coli, showing instead that two concurrent processes set division on competing time scales.

Size control in mammalian cells involves modulation of both growth rate and cell cycle duration

The paper measures single-cell volume over cell cycles in mammalian cells and finds size homeostasis relies on both growth rate and cell cycle duration modulation.
