The wild tomato species Solanum chilense is divided into geographically and genetically distinct populations that show signs of defense gene selection and differential phenotypes when challenged with several phytopathogens, including the oomycete causal agent of late blight Phytophthora infestans. To better understand the phenotypic diversity of th...

Background: Coevolution is a selective process of reciprocal adaptation in hosts and parasites or in mutualistic symbionts. Classic population genetics theory predicts the signatures of selection at the interacting loci of both species, but not the neutral genome-wide polymorphism patterns. To bridge this gap, we build an eco-evolutionary model, w...

Coevolution is a selective process of reciprocal adaptation between antagonistic or mutualistic symbionts and their host. Classic population genetics theory predicts the signatures of selection at the interacting loci but not the neutral genome-wide polymorphism patterns. We here build a coevolutionary model with cyclic changes in the host and para...

Seed (egg) banking is a common bet-hedging strategy maximizing the fitness of organisms facing environmental unpredictability by the delayed emergence of offspring. Yet, this condition often requires fast and drastic stochastic shifts between good and bad years. We hypothesize that the host seed banking strategy can evolve in response to coevolutio...

The degradation of coffee cream quality, in different packaging and exposed to different lamps, was evaluated. Coffee cream is often retailed in packaging highly permeable to light and oxygen with high surface-to-volume ratio; therefore, riboflavin-containing coffee cream is sensitive to photooxidative reactions. Light-emitting diodes (LEDs) or sod...

Many life-history traits are important determinants of the generation time. For instance, semelparous species whose adults reproduce only once have shorter generation times than iteroparous species that reproduce on several occasions, assuming equal development duration. A shorter generation time ensures a higher growth rate in stable environments...

Iteroparous individuals reproduce several times, whereas semelparous reproduce just once. Many species are iteroparous to various degrees, despite a well-known advantage to semelparous genotypes: they grow more rapidly in stable environments where resources are in excess. Semelparity looses its selective advantage when resources become limiting, an...
