Phylogeny structures species' interactions in experimental ecological communities

This paper introduces a framework to test if phylogeny influences species interactions and abundance in ecological communities, finding strong phylogenetic signal across experiments.

Coexistence of many species under a random competition-colonization trade-off

The paper investigates coexistence in metacommunities under a competition-colonization trade-off, finding that half of species in a large pool typically coexist without saturation.

Ranking species based on sensitivity to perturbations under non-equilibrium community dynamics

The paper introduces two methods to rank species by sensitivity to perturbations using time-varying Jacobian matrices and applies them to empirical time series to show sensitive species are harder to forecast.

Habitat heterogeneity, environmental feedbacks, and species coexistence across timescales

The paper develops a modeling framework to study species coexistence in heterogeneous environments and how environmental feedbacks influence community dynamics across timescales.

Modeling ecological communities when composition is manipulated experimentally

The paper introduces methods to infer species interactions from experimental ecological community data, demonstrating their effectiveness across multiple taxa and simulations.

No robust coexistence in a canonical model of plant-soil feedbacks

The paper shows that a canonical plant-soil feedback model cannot support coexistence of more than two species, suggesting the need for alternative frameworks to explain diversity in natural communities.

Intraspecific variation stabilizes classic predator-prey dynamics

The paper shows that intraspecific variation stabilizes predator-prey dynamics without requiring direct self-regulation, challenging assumptions in ecological models.

Metapopulations with habitat modification

The paper extends a metapopulation model to include habitat modification by species, showing that memory of previous occupants can enable coexistence and increase diversity-robustness relationships.

Effects of phylogeny on coexistence in model communities

This study uses a model to show how phylogenetic trees and species traits influence coexistence in communities.

Tractable models of ecological assembly

The paper examines conditions under which top-down and bottom-up ecological assembly models produce equivalent coexisting species sets, using network representations to analyze community dynamics.

Predicting coexistence in experimental ecologicalcommunities

The paper presents a statistical method to predict coexistence and species abundances in experimental ecological communities using limited experiments, achieving high accuracy without assuming system dynamics.

Ecological networks: Pursuing the shortest path, however narrow and crooked

The paper analyzes ecological network studies using shortest paths, identifying methodological issues in edge weight handling and proposing a checklist for better practices.
