Sparsity of higher-order landscape interactions enables learning and prediction for microbiomes

This paper introduces a mechanism-agnostic method to predict microbial community compositions and functions using sparse representations and compressive sensing, validated on both simulated and experimental data.

Universal abundance fluctuations across microbial communities, tropical forests, and urban populations

The paper analyzes time-series data from microbial communities, tropical forests, and urban populations using a shared stochastic model, revealing similar parameter space occupancy despite different scales.

Functional universality in slow-growing microbial communities arises from thermodynamic constraints

The paper develops a consumer-resource model to show that thermodynamic constraints drive functional convergence in slow-growing microbial communities, validated by experimental data from anaerobic digesters.

Ecological landscapes guide the assembly of optimal microbial communities

The paper investigates how ecological landscapes influence the success of heuristic strategies in assembling optimal microbial communities using consumer-resource models and experimental data.

Fin Shape, Asymmetry, and Evolutionary Ecomorphology in Triggerfishes and Filefishes (Superfamily: Balistoidea)

The paper quantifies morphological diversity in balistoid fishes and finds convergence in fin shapes related to swimming performance and ecological niches.

Complementary resource preferences spontaneously emerge in diauxic microbial communities

This study develops a model of diauxic microbial communities and finds that complementary resource preferences emerge spontaneously during community assembly.

Traveling fronts in self-replicating persistent random walks with multiple internal states

The paper analyzes traveling fronts in self-replicating persistent random walks with multiple internal states, deriving expansion velocity formulas and showing discontinuous transitions in propagation.

Functional Morphology of Endurance Swimming Performance and Gait Transition Strategies in Balistoid Fishes

This study examines how fin and body shapes in balistoid fishes relate to swimming performance and gait transitions, finding that high aspect ratio fins correlate with higher critical swimming speeds.

Chirality provides a direct fitness advantage and facilitates intermixing in cellular aggregates

The paper shows that chirality provides a fitness advantage and promotes intermixing in cellular aggregates through bulge formation during competition.

Pinned, locked, pushed, and pulled traveling waves in structured environments

The paper studies how traveling waves in structured environments can become pinned or locked, showing that locked velocities depend on environmental periodicity and are robust to fluctuations.
