Using refuge plants to manage resistance evolution and crop yield in agricultural fields

This study shows that varying toxicity and refuge frequency over pest generations is more effective for managing pesticide resistance than keeping them constant, with outcomes depending on population parameters and mating behaviors.

A metabolic model to investigate the evolution of chemodiversity

The paper develops a metabolic model to compare hypotheses about the evolution of chemodiversity, finding support for the interaction diversity hypothesis over the screening hypothesis.

How does individual trait variation impact the survival of populations with an Allee effect?

This study investigates how intraspecific trait variation impacts population survival under Allee effects using individual-based models, finding that ITV can hinder survival in mate-finding Allee effects but benefit survival in predator-driven Allee effects.

Individualised niches in a variable environment - Consequences for environmental change responses

The paper develops a mathematical model integrating intraspecific trait variation and niche conformance/construction to assess population fitness in changing environments, applying it to case studies on great tits and a host-parasite system.

Adaptive rewiring and temperature tolerance shape the architecture of plant-pollinator networks globally

The paper models how temperature affects plant-pollinator networks by integrating temperature tolerance and adaptive rewiring, showing declines in specialization and increases in connectance and nestedness with rising temperatures.

Can the marginal male hypothesis explain spatial density variation in pinnipeds?

The paper tests if the marginal male hypothesis combined with density-dependent pup survival can explain density differences between pinniped colonies.

Evolution of genetic variance and its consequences oneco-evolutionary response in complex mutualistic networks

This study shows that evolving genetic variance and network architecture enhance resilience of plant-pollinator networks to temperature shifts by promoting faster adaptation and reducing trait lag.

The role of evolving niche choice in herbivore adaptation to host plants

This study uses an individual-based model to show that niche choice slows insecticide resistance evolution and promotes phenotypic coexistence in phytophagous insects.

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.
