Understanding the phytochemical diversity of plants: Quantification, variation and ecological function

This paper examines phytochemical diversity (chemodiversity) in plants, discussing its ecological relevance, reviewing methodological practices, and outlining future research directions.

How does plant chemodiversity evolve? Testing five hypotheses in one population genetic model

The paper develops a population genetic model to test five hypotheses about the evolution of plant chemodiversity, finding support for some hypotheses and partial support for others.

Reviving collapsed networks from a single species: the importance of trait variation and network architecture

The paper shows that perturbing a single species can revive collapsed mutualistic networks, even under unfavorable conditions, by leveraging network architecture and trait variation.

Multi-scale Effects of Habitat Loss and the Role of Trait Variation

This study shows habitat loss affects neighboring patches and the landscape, with trait variation influencing consumer resilience and extinction risks.

Modeling the genetic footprint of fluctuating balancing selection: From the local to the genomic scale

The paper models the genetic footprint of fluctuating balancing selection and shows it increases diversity near selected sites but reduces it elsewhere, potentially lowering genome-wide diversity.

Modeling minimum viable population size with multiple genetic problems of small populations

The paper develops eco-evolutionary models to estimate minimum viable population sizes by incorporating genetic problems like inbreeding depression, mutation accumulation, and genetic drift.

Quantifying the effects of intraspecific trait variation and interspecific trait correlations on interacting populations - a nonlinear averaging approach

This paper develops a nonlinear averaging framework to quantify how intraspecific trait variation and interspecific trait correlations affect ecological interactions between species.

Waiting for love but not forever: modelling the evolution of waiting time to selfing in hermaphrodites

The paper models how waiting time to selfing evolves in hermaphrodites under different population densities and finds that mixed mating systems are not stable under the considered conditions.

Climate change and green sea turtle sex ratio - Preventing possible extinction

The paper models how climate change affects green sea turtle sex ratios and shows nest depth evolution could help prevent extinction, though extreme scenarios still pose risks.

Models for Eco-evolutionary Extinction Vortices and their Detection

The paper develops quantitative models to describe and detect eco-evolutionary extinction vortices caused by genetic drift and loss of variation in small populations.

Density dependence on multiple spatial scales maintains spatial variation in both abundance and traits

The paper shows how interactions between patches can maintain spatial variation in density and traits through eco-evolutionary feedbacks.

Segregation lift: A general mechanism for the maintenance of polygenic variation under seasonally fluctuating selection.

The paper introduces a mechanism called segregation lift that explains how polygenic variation can be maintained under seasonally fluctuating selection by considering dominance and epistasis in multi-locus models.

Eco-evolutionary buffering: rapid evolution facilitates regional species coexistence despite local priority effects

The paper develops an eco-evolutionary model showing that rapid evolution allows species coexistence despite local priority effects by reducing resistance to interference in common species.
