Phylogenetic, geographical, and temporal analysis of female reproductive trade-offs in Drosophilidae

The fact that reproductive effort often shows trade-offs with other necessary functions and features of living organisms has been recognized for centuries. Darwin (1872, pg. 142) gives credit to Geoffroy St. Hilaire and Goethe for proposing the law of "Compensation or Balancement of Growth" and ascribes the following quote to Goethe, "In order to spend on one side, nature is forced to economize on the other side." The essence of this law is captured in modern theories and syntheses (Lack, 1947; Cody, 1966; Smith and Fretwell, 1974; Stearns, 1976, 1977, 1992) that emphasize time, energy budgets, and physiological, genetic and phylogenetic associations that govern the form of compensation that results in a trade-off

A standardized nomenclature and atlas of the male terminalia of Drosophila melanogaster

International audienceAnimal terminalia represent some of the most diverse and rapidly evolving structures in the animal kingdom, and for this reason have been a mainstay in the taxonomic description of species. The terminalia of Drosophila melanogaster, with its wide range of experimental tools, have recently become the focus of increased interest in the fields of development, evolution, and behavior. However, studies from different disciplines have often used discrepant terminologies for the same anatomical structures. Consequently, the terminology of genital parts has become a barrier to integrating results from different fields, rendering it difficult to determine what parts are being referenced. We formed a consortium of researchers studying the genitalia of D. melanogaster to help establish a set of naming conventions. Here, we present a detailed visual anatomy of male genital parts, including a list of synonymous terms, and suggest practices to avoid confusion when referring to anatomical parts in future studies. The goal of this effort is to facilitate interdisciplinary communication and help newcomers orient themselves within the exciting field of Drosophila genitalia. ARTICLE HISTOR
