Collective dynamical regimes predict invasion success and impacts in microbial communities

The paper shows that invasion success and impacts in microbial communities depend on dynamics, interaction strength, and diversity, with more fluctuating and diverse communities being more invasible and having larger ecological effects.

Getting More by Asking for Less: Linking Species Interactions to Species Co-Distributions in Metacommunities

This paper shows that inferring precise species interactions from spatial distribution patterns is challenging, but estimating statistical moments of interaction distributions is more robust.

Emergent phases of ecological diversity and dynamics mapped in microcosms

The paper demonstrates predictable emergent diversity and dynamics in microbial ecosystems by showing transitions between distinct dynamical phases as species number or interaction strength increases.

Local and collective transitions in sparsely-interacting ecological communities

The paper studies ecological community transitions under varying interaction strengths, identifying regime shifts and collective transitions in sparse interaction networks.

Directionality and community-level selection

The paper shows that competitive ecological communities can exhibit long-lasting directionality under high diversity, leading to community-level selection through a maturity function.

Fingerprints of high-dimensional coexistence in complex ecosystems

This study explores high-dimensional coexistence in ecosystems using grassland biodiversity data, showing that biodiversity arises from collective organization rather than individual species interactions.

Dynamical persistence in resource-consumer models

The paper shows that ecological communities with high diversity can exhibit persistent abundance fluctuations due to resource competition and migration, depending on the ratio of species diversity to resources.

Can endogenous fluctuations persist in high-diversity ecosystems?

The paper shows high-diversity spatial ecosystems can exhibit persistent non-equilibrium states with chaotic dynamics, driven by endogenous fluctuations rather than external perturbations.

Generic assembly patterns in complex ecological communities

The paper shows that generic behaviors in ecological communities can be predicted using a random model, highlighting the role of statistical properties over detailed structure.
