Sleep is nearly ubiquitous throughout the animal kingdom, yet little is known about how
ecological factors or perturbations to the environment shape the duration and timing of …

Understanding the phenotypic and molecular mechanisms that contribute to genetic
diversity between and within species is fundamental in studying the evolution of species. In …

Fruit flies of the genus Drosophila have been an attractive and effective genetic model
organism since Thomas Hunt Morgan and colleagues made seminal discoveries with them …

A major challenge of biology is understanding the relationship between molecular genetic
variation and variation in quantitative traits, including fitness. This relationship determines …

Abstract Drosophila suzukii (Matsumura)(Diptera: Drosophilidae) is a pest of small fruits and
cherries, and has also been noted to infest a variety of wild, ornamental, and uncultivated …

In many species, genomic data have revealed pervasive adaptive evolution indicated by the
fixation of beneficial alleles. However, when selection pressures are highly variable along a …

Drosophila suzukii ovoposits and feeds on healthy fruits, unlike most other Drosophila
species. It has been traditionally reported from Asia, but in the last 2 years it has been …

Life history theory seeks to explain the evolution of the major features of life cycles by
analyzing the ecological factors that shape age-specific schedules of growth, reproduction …

The Asiatic fruit fly Drosophila suzukii has recently invaded Europe and North and South
America, causing severe damage to fruit production systems. Although agronomic host …

Life-history traits or “fitness components”—such as age and size at maturity, fecundity and
fertility, age-specific rates of survival, and life span—are the major phenotypic determinants …
