Alfredo Vicente Peretti is Principal Researcher of the Consejo Nacional de Investigaciones Científicas y Técnicas de la Argentina, Instituto de Diversidad y Ecología Animal (CONICET-IDEA) and Associate Professor of the Departamento de Diversidad Biológica y Ecología, Facultad de Ciencias Exactas Físicas y Naturales, Universidad Nacional de Córdoba, Argentina. His main areas of interest and research are in zoology, with emphasis on invertebrates. He works on behavior, ecology and evolution, especially in the field of reproductive biology using arthropods as models. Lucia Calbacho-Rosa is an Associate Researcher at the Consejo Nacional de Investigaciones Científicas y Técnicas de la Argentina, Instituto de Diversidad y Ecología Animal (CONICET-IDEA). Her main research areas are behavior, reproductive biology, sexual selection and studies of genital morphology using arthropod species as models. Paola Andrea Olivero is an Assistant Researcher at the Consejo Nacional de Investigaciones Científicas y Técnicas de la Argentina, Instituto de Diversidad y Ecología Animal (CONICET-IDEA). and Associate Professor of general biology at the Facultad de Ciencias Exactas, Físicas y Naturales of the Universidad Nacional de Córdoba, Argentina. Her research is related to the study of the reproductive biology, analyzing courtship behavior and patterns of differential paternity in arthropods. Mariela Oviedo-Diego is Postdoctoral Fellow at the Consejo Nacional de Investigaciones Científicas y Técnicas de la Argentina, Instituto de Diversidad y Ecología Animal (CONICET-IDEA) and a vocational teacher of entomology at the Facultad de Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba, Argentina. Her research has focused on sexual behavior, the study of pre- and postcopulatory characters, and reproductive interference in different arachnid species. David Eduardo Vrech is Associate Researcher at the Consejo Nacional de Investigaciones Científicas y Técnicas de la Argentina, Instituto de Diversidad y Ecología Animal (CONICET-IDEA) and Assistant Professor specializing in invertebrate biology at the Facultad de Ciencias Exactas, Físicas y Naturales, Universidad Nacional de Córdoba, Argentina.
