The paper investigates whether sporophytic self-incompatibility breaks down more easily in tetraploid compared to diploid populations, finding that dominance relationships significantly influence this outcome.

The paper develops a statistical framework to estimate different sources of variation in prey-predator interactions, showing how experimental design affects parameter identifiability.

This study develops a unified Wright-Fisher model to analyze mutation fate on Y chromosomes and autosomes, showing overdominant mutations are more likely to fix on Y chromosomes due to segregation time effects.

The paper analyzes floral and reproductive traits across 361 flowering plant species to show that dioecy is linked to floral traits, while correlations with lifespan and dispersal are spurious.

The paper challenges the belief that environmental and individual variabilities drive prey consumption rate variation, showing stochastic foraging paths are the main driver.

The paper identifies a hemizygous genomic region containing a gibberellin pathway gene that controls self-incompatibility in Oleaceae plants, linking GA catabolism to SI responses.

The paper develops a stochastic birth-death model with competitive interactions and uses Approximate Bayesian Computation to infer ecological, demographic, and genetic parameters from genetic data.
