Assembly archetypes in ecological communities

The paper identifies assembly archetypes in ecological communities using mathematical formalism and clinical data, distinguishing healthy from unhealthy gut microbiota.

Feasibility in MacArthur's Consumer-Resource Model

This paper identifies conditions for feasibility in MacArthur's consumer-resource model and shows how system complexity and resource growth affect feasibility.

On the limits to invasion prediction using coexistence outcomes

This study examines the limits of predicting invasion outcomes from coexistence outcomes using a Lotka-Volterra framework, showing varying degrees of translatability between different ecological dynamics.

Integrating metabolic scaling and coexistence theories

This paper integrates metabolic scaling and coexistence theories to explain community-level patterns in population abundance and biomass density across body sizes.

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.

Understanding the state-dependent impact of species correlated responses on community sensitivity to perturbations

The paper introduces a framework to analyze how species correlations affect community sensitivity to perturbations over time, showing these impacts vary with species abundance and can be detected in time series data.

Understanding the impact of third-party species on pairwise coexistence

The paper investigates how third-party species affect pairwise coexistence probabilities in multispecies systems under environmental uncertainty, showing that their impact varies across different pairs.

Rapid monitoring for ecological persistence

The paper shows that persistence of small ecological subnetworks can reliably predict the persistence of entire ecological networks, aiding conservation efforts.

Protection promotes energetically efficient structures in marine communities

This study shows that full marine protection leads to more top-heavy, energetically efficient marine communities through theoretical and empirical analysis.

Towards a system-level causative knowledge of pollinator communities

This paper proposes a probabilistic causal analysis approach to improve system-level understanding of pollinator communities by integrating observational and synthetic data.

Feasibility conditions of ecological models: Unfolding links between model parameters

This paper develops a general formalism to derive feasibility conditions for ecological models without solving equilibrium locations, enabling analytical relationships between parameters in complex models.

Plant-insect chemical communication in ecological communities: an information theory perspective

The paper introduces an information theory framework to study plant-insect chemical communication at the community level, aiming to understand ecological network dynamics under global changes.

Untangling the complexity of priority effects in multispecies communities

This paper develops a theoretical framework to classify priority effects in multispecies communities and demonstrates its utility using neural networks and experimental data.

Coexistence holes characterize the assembly and disassembly of multispecies systems

The paper introduces a hypergraph-based formalism to analyze coexistence in multispecies systems, revealing predictable discontinuities called coexistence holes.

Understanding the emergence of contingent and deterministic exclusion in multispecies communities

The paper develops a theoretical framework to explain deterministic and contingent competitive exclusion in multispecies communities using an empirical plant competition system.

Bridging parametric and nonparametric measures of species interactions unveils new insights of non-equilibrium dynamics

This paper bridges parametric and nonparametric measures of species interactions to reveal new insights into non-equilibrium ecological dynamics.

The impact of colonization history on the composition of ecological systems

This paper develops a theory linking colonization history to community composition, showing that community size, species connectivity, and growth rate variation influence the dominance of colonization history.

Truncated WT1 protein isoform expression is increased in MCF-7 cells in a long-term estrogen depletion.

This study examines WT1 isoform expression in MCF-7 cells under long-term estrogen depletion, finding increased 36-38 kDa isoform expression and decreased sensitivity to tamoxifen.

Is the addition of higher-order interactions in ecological models increasing the understanding of ecological dynamics?

This study evaluates whether higher-order interactions in ecological models improve understanding of dynamics by analyzing the number of free-equilibrium points in Lotka-Volterra models.

Rethinking the importance of the structure of ecological networks under an environment-dependent framework

The paper argues that the importance of ecological network structures depends on environmental perturbations and proposes a framework to study this relationship systematically.
