![]() There was a longer peak in the morning in the coastal area, and a higher peak in the evening in the mountains, where activity starts later and becomes less intense earlier. Activity patterns were different in the two study areas (W = 6.77, p = 0.034). Activity peaked in the morning soon after sunrise and then before and during dusk. Activity patterns were diurnal and bimodal, and animals were active for 14-15 hours each day. ![]() A total of 49 photos were taken in the mountains and 152 in the coastal area. Camera traps were used to gather data in two protected areas (one montane and other coastal) in the state of Espírito Santo, southeastern Brazil. Here we examine temporal activity in the Red-rumped Agouti ( Dasyprocta leporina) in two fragments of Atlantic Forest and those factors that influence the circadian rhythm in the study areas. "Dasyprocta leporina" (On-line), Animal Diversity Web.Timing of activity is a consequence of adaptations to daily and seasonal changes in the environment and examining these patterns is important to better understand the temporal niches of the species. Mammals of Neotropics: Ecuador, Bolivia and Brazil. "The agouti Dasyprocta leporina (Rodentia: Dasyproctidae) as seed disperser of the palm Astrocaryum aculeatissimum". ^ Pires, Alexandra Galetti, Mauro (December 2012).^ a b "Dasyprocta leporina (Red-rumped Agouti)" (PDF).Mammal Species of the World: A Taxonomic and Geographic Reference (3rd ed.). They are known to feed on and disperse Astrocaryum aculeatissimum seeds, as well as Hymenaea courbaril seeds. They also feed on insect larvae when plant resources are low. Dietįood mostly consists of seeds, pulp, leaves, roots and fruits. Most animals in the family Dasyproctidae mate once or twice, and it is presumed to be true for the red-rumped agouti as well. They need large areas for food, breeding, and territory because of this, keeping them in captivity is difficult. They live in pairs or family groups of the parents and babies. On average, it takes 20 weeks for the young to be weaned. They have no distinct breeding season, and females generally have about one to three young. They can be distinguished from other agoutis by their distinct coloring. The front feet have four toes and the back have three each. The fur becomes more orange as it goes past (going down) the middle area of the animal. They are brownish with darker spots on the upper body. The females are larger than males but otherwise look similar. They are about 19 to 25 inches (48 to 64 cm) long. Red-rumped agoutis weigh about 3 to 6 kilograms (6.6 to 13.2 lb). Parental Investment: precocial pre-fertilization (Provisioning, Protecting: Female) pre-hatching/birth (Provisioning: Female, Protecting: Female) pre-weaning/fledging (Provisioning: Female, Protecting: Female) post-independence association with parentsĬaptive specimen at Henry Vilas Zoo in the United States The roles of mothers and fathers in parental care have not been documented for these animals. Juveniles of both sexes might remain with their parents after 20 weeks of age, though males are more likely to disperse than females. Members of the family Dayproctidae generally give birth to fewer, larger offspring than do other rodents, and spend a good amount of time and energy raising their young. Juvenile agoutis are born into a world rich with predators, and the ability to run within an hour of birth greatly increases their chance of survival. Key Reproductive Features: iteroparous gonochoric/gonochoristic/dioecious (sexes separate) sexual fertilization viviparousĪverage age at sexual or reproductive maturity (female)Īgoutis often live in small groups consisting of a breeding pair and their offspring, though young are precocial and can forage soon after birth. leporina are unavailable, other members of Dasyproctidae have estrus cycles lasting approximately 34 days and wean their offspring around 20 weeks of age.īreeding interval: The breeding interval for these animals is not known.īreeding season: The breeding season for D. It is reasonable to assume that Brazilian agoutis are similar to other Dasyproctids.īrazilian agoutis tend to have 1 to 3 offspring at a time after a gestation period of 104 to 120 days. leporina are not available, other species in the family Dasyproctidae mate for life and breed twice annually if enough food is available. They are fairly social animals, and perhaps stick together for mating and safety purposes. Agoutis need a large area to court and breed, so they do not reproduce well in captivity. Brazilian agoutis are monogamous, and often live in pairs or small family groups consisting of parents and their offspring.
