Somos un entusiasta grupo de investigadores, docentes, becarios y estudiantes enfocados en la biología reproductiva de los artrópodos, con énfasis en la evolución de los rasgos sexuales entre los arácnidos.
Iniciamos este camino hace 10 años para ofrecer un lugar de investigación y docencia en nuestro país en esta apasionante temática. Junto con estudios de biodiversidad y filogenia, queremos mostrar una perspectiva integrada de los arácnidos.
Líneas de investigación
- Estudio comparado y experimental de patrones y mecanismos de selección sexual
- Biodiversidad y filogenia de grupos seleccionados de arácnidos
- Exploración de la fenología y ecología reproductiva
- Divulgación de nuestro conocimiento científico mediante publicaciones y docencia
