The paper extends the allometric trophic network framework to model time-varying phytoplankton subsidies in a Chilean intertidal ecosystem, revealing differential species responses and increased extinction risk for predators.

The paper analyzes wild bee diversity over a century at a preserve, finding declining species richness and traits associated with extinction risk.

The paper uses random forest models to analyze an ontogenetic consumer-resource model, revealing ecological mechanisms that influence stability.

The paper develops a Bayesian method to estimate plant-pollinator network structure from noisy observational data and applies it to Seychelles data.

The paper develops population dynamic models to compare pollination and seed dispersal mutualisms, finding they exhibit different stability dynamics at low density depending on plant carrying capacity, animal foraging efficiency, and obligacy.

The paper assesses how coastal productivity changes and artisanal fisheries interact to affect a marine food-web using network analysis and bioenergetic modeling.

The paper develops extensible models for two-species mutualisms to evaluate population-level consequences of different mechanisms and proposes a general ecological theory of mutualism.

NetworkExtinction simulates extinction propagation and rewiring in ecological networks, quantifying robustness and secondary extinctions in response to species loss.

The paper shows that reduced temporal resource overlap increases pollinator specialization, using mechanistic models and empirical pollen load data from bees with different flight periods.

This study shows that mutualistic interactions, particularly pollination, enhance diversity, stability, and function in food webs by increasing persistence, productivity, and abundance of species.

The paper integrates economic drivers into ecological networks to analyze fishery sustainability, finding that harvesting high biomass species can threaten long-term sustainability by inducing extinction cascades.
