Site-suitability difference and the expectation of species richness difference in stochastic two-subcommunities models

The paper develops a theoretical framework to predict species richness differences between subcommunities using presence-absence data and null models.

Jaccard dissimilarity in stochastic community models based on the species-independence assumption

The paper develops probabilistic models to analyze beta-diversity by considering species presence probabilities across sites and applies them to woodpecker distribution data.

Species interactions and diversity: a unified framework using Hill numbers

This paper unifies models of biotic interactions with diversity measurements, showing that biodiversity changes can arise from various interactions and that traditional diversity analyses obscure absolute abundance changes.

Partitioning the temporal changes in abundance-based beta diversity into loss and gain components

The paper develops a method to partition temporal changes in beta diversity into loss and gain components, revealing homogenization in fish communities driven by species abundance gains.

Reproductive interference hampers species coexistence despite conspecific sperm precedence

This study shows reproductive interference reduces coexistence of closely related species with conspecific sperm precedence, even when they share habitats.

Solving the sex ratio scandal in Melittobia wasps

The paper resolves the sex ratio discrepancy in Melittobia wasps by showing that females adjust their sex ratio based on dispersal status and relatedness in natural settings, contrasting with laboratory experiments.

Cooperative interactions among females and even more extraordinary sex ratios

The paper investigates how cooperative interactions among females can lead to more extreme female-biased sex ratios than predicted by Hamilton's local mate competition theory, using wasp species as a case study.

Eco-evolutionary dynamics of prior selfing rate promotes the coexistence without niche partitioning under reproductive interference

This study shows that the evolution of prior selfing can promote coexistence between plant species under reproductive interference without niche partitioning.

The evolution of stage-specific virulence: differential selection of parasites in juveniles

This paper develops a stage-structured epidemiological model to show how juvenile and adult virulence evolve under different transmission and demographic conditions.
