Alometría evolutiva en el órgano reproductor masculino de histricomorfos (Rodentia: Hystricomorpha)570 - BiologíaBáculoSaco intromitenteSelección sexualOs penisBiologíaZoologíaEvoluciónGenética animalFiguras.La genitalia masculina está compuesta la uretra, músculos y ocasionalmente una estructura ósea interna denominada báculo. En Hystricomorpha, este presenta una invaginación llamada saco intromitente, que contiene un par de espinas evertibles durante la cópula. El conocimiento sobre la funcionalidad y evolución de estas estructuras es aún limitado. El objetivo de este estudio es evaluar la alometría de los elementos genitales masculinos en histricomorfos, su variación entre familias y sistemas de apareamiento, y explorar la relación del tamaño del báculo con factores geográficos. Se recopilaron medidas corporales de los genitales, así como información geográfica. Se realizaron regresiones del Eje Mayor Reducido para evaluar la relación entre las variables recopiladas en histricomorfos, así como entre familias y sistemas reproductivos. Además, se realizaron regresiones de Mínimos Cuadrados Ordinarios para analizar la relación entre la latitud y el área de distribución con la longitud del báculo. En histricomorfos, el báculo presentó alometría negativa, pero en Octodontidae no hubo relación entre ambas variables, y Ctenomyidae presentó alometría negativa con baja correlación. Las especies poligínicas y promiscuas no mostraron relación entre el tamaño corporal y la longitud del báculo, mientras que las monógamas presentaron alometría negativa. No hubo relación con las variables geográficas. Estos resultados sugieren selección directa en Octodontidae y Ctenomyidae, así como en especies poligínicas y promiscuas, mientras que, en las monógamas, se presenta selección indirecta. No obstante, se requieren más descripciones de la morfología de histricomorfos, para realizar análisis integrativos que abarquen mayor cantidad de familias taxonómicas.The male genitalia are composed of the urethra, muscles, and occasionally an internal bony structure known as the baculum. In Hystricomorpha, this structure presents an invagination called the intromittent sac, which contains a pair of spines that are everted during copulation. Knowledge about the functionality and evolution of these structures remains limited. The objective of this study is to evaluate the allometry of male genital elements in hystricomorphs, their variation among families and mating systems, and to explore the relationship between baculum size and geographic factors. Body and genital measurements, as well as geographic information, were collected. Reduced Major Axis regressions were performed to evaluate the relationships among the variables in hystricomorphs, and among families and reproductive systems. Additionally, Ordinary Least Squares regressions were conducted to analyze the relationship between latitude and distribution area with baculum length. In hystricomorphs, the baculum exhibited negative allometry, however, in Octodontidae no relationship was found between these variables, and Ctenomyidae showed negative allometry with low correlation. Polygynous and promiscuous species showed no relationship between body size and baculum length, whereas monogamous species exhibited negative allometry. No relationship was found with the geographic variables. These results suggest direct selection in Octodontidae and Ctenomyidae, as well as in polygynous and promiscuous species, whereas indirect selection is present in monogamous species. Nevertheless, more descriptions of hystricomorph morphology are required to conduct integrative analyses encompassing a greater number of taxonomic families.Introducción -- Materiales y métodos -- Trayectorias de crecimiento -- Sistemas de apareamiento y familias taxonómicas -- Resultados -- Trayectorias de crecimiento -- Sistemas de apareamiento y familias taxonómicas -- Relación geográfica -- Discusión -- Conclusiones -- Referencias bibliográficasPregradoBiólogo(a)MastozoologíaUniversidad de CaldasFacultad de Ciencias Exactas y NaturalesManizales, CaldasBiologíaRamírez Chaves, Héctor EmilioUniversidad de CaldasArboleda-Osorio, Juan José2026-01-23T16:33:32Z2026-01-23T16:33:32Z2026-01-23Trabajo de grado - Pregradohttp://purl.org/coar/resource_type/c_7a1fTextinfo:eu-repo/semantics/bachelorThesis32 páginasapplication/pdfapplication/pdfapplication/pdfapplication/pdfhttps://repositorio.ucaldas.edu.co/handle/ucaldas/26539Universidad de CaldasRepositorio Institucional Universidad de Caldasrepositorio.ucaldas.edu.cospaAdams, D.
