Variability of functional and biodiversity responses to perturbations is predictable and informative

The paper shows that variability in community-level responses to perturbations is predictable and provides insights into hidden features of ecosystem functions and species responses.

The distribution of distances to the edge of species coexistence

The paper derives an analytical distribution of distances to the edge of species coexistence in Lotka-Volterra models, using interaction matrices and applies it to experimental plant community data.

A taxonomy of multiple stable states in complex ecological communities

The paper investigates multiple stable states in complex systems, identifying four regimes of multistability and their fingerprints, which can be used to analyze regime shifts in ecological communities.

Identifying the limits where variation in consumer stable isotope values reflect variation in diet

The paper examines how variation in consumer stable isotope values relates to diet variability and other confounding factors, showing how quantitative corrections can improve interpretation.

How collectively integrated are ecological communities?

The paper investigates whether ecological community dynamics depend more on direct species interactions or indirect feedbacks, showing that the spectral radius of the interaction matrix determines the contribution of indirect pathways.

Heating tolerance of ectotherms is explained by temperature's non-linear influence on biological rates

The paper shows that ectotherms' heating tolerance is consistent across acclimation temperatures when accounting for temperature's non-linear effects on biological rates.

Why scaling up uncertain predictions to higher levels of organisation will underestimate change

The paper shows that scaling up uncertain predictions from species to ecosystem levels underestimates system-level change due to dimensional effects in complex systems.

Fitness and community feedbacks: the two axes that drive long-term invasion impacts

The paper develops an analytical method to predict long-term community impacts of invasions by considering fitness and feedback mechanisms across different ecological models.

Can biomass distribution across trophic levels predict trophic cascades?

This study shows that biomass distribution and trophic cascades are linked through trophic dissipation, using data from aquatic mesocosm experiments.

The inherent multidimensionality of temporal variability: How common and rare species shape stability patterns

The paper shows how variability in ecological communities, viewed as a response to stochastic perturbations, reveals stability properties shaped by common and rare species.

Plant-soil feedbacks trigger tannin evolution by niche construction: a spatial stoichiometric model

The paper models plant-soil feedbacks and herbivory to show how tannin evolution is driven by soil nitrogen dynamics and mycorrhizal associations in unproductive environments.

The impact of spatial and temporal dimensions of disturbances on ecosystem stability

This study investigates how spatial and temporal features of disturbances affect ecosystem stability using three models, finding that disturbance extent and frequency interact to influence recovery and persistence.

The three regimes of spatial recovery

The paper identifies three recovery regimes in spatially structured ecosystems and their implications for population stability and response to disturbances.

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.

How ecosystems recover from pulse perturbations: A theory of short- to long-term responses

This paper explains why short-term recovery rates in ecosystems differ from long-term resilience, showing that short-term responses depend on perturbation distribution and species abundance.
