TL;DR: The behavioral ecology of the Central American agouti, a large caviomorph rodent living on Barro Colorado Island in the Panama Canal Zone is described, which includes social structure, activity patterns, maturation, courting, agonistic and comfort behavior, and acoustic, vocal, visual, and olfactory communication systems, as well as the interrelationship of the animals' behavior with the environment.
Abstract: Smythe, Nicholas. The Natural History of the Central American Agouti (Dasyprocta punctata). Smithsonian Contributions to Zoology, number 257, 52 pages, 25 figures, 2 tables, 1978.—In this report the behavioral ecology of the Central American agouti (Dasyprocta punctata), a large caviomorph rodent, living on Barro Colorado Island in the Panama Canal Zone is described. This two phase study includes social structure, activity patterns, maturation, courting, agonistic and comfort behavior, and acoustic, vocal, visual, and olfactory communication systems, as well as the interrelationship of the animals' behavior with the environment.

TL;DR: In this article, the authors investigated the movements and home range of Dasyprocta punctata on Barro Colorado Island, Panama, and found that the agoutis are central-place foragers.
Abstract: This study investigates the movements and home range of the agouti (Dasyprocta punctata) on Barro Colorado Island, Panama. We captured and tracked 12 agoutis from January to December 2003. Home-range size (95% kernel) ranged from 1.56–2.45 ha (n = 6) for males and 1.34–1.97 ha (n = 5) for females. Agouti ranges overlapped and we estimated a density of approximately 100 agoutis km−2. We compared agouti movement with the locations of refuges and food trees, and the results suggest that the agoutis are central-place foragers. Agoutis moved an average of 850 m d−1 covering approximately 35% of their range daily. These movement data help us understand the potential impacts of agoutis as seed dispersers, predicting that D. punctata will encounter and hoard fallen fruit within 10–200 m (i.e. radius of home range) of its source, and move seeds towards refuges such as ground holes and dense vegetation around recent tree falls.

TL;DR: Two adult male and three adult female agoutis have been reproducing at the Lincoln Park Zoo since 1978, and it is believed that they are likely to produce multiple offspring in captivity.
Abstract: Two adult male and three adult female agoutis have been reproducing at the Lincoln Park Zoo since 1978. Agoutis of the species D. punctata and D. fuliginosa are capable of breeding and producing offspring in every month of the year in captivity. The minimum interbirth interval of captive punctata is 127 days, and its gestation period is apparently less than 127 calendar days. In captivity, agoutis are likely to produce multiple offspring.

TL;DR: The implementation of artificial drinking fountains in the RBC during the dry season was a successful action to mitigate the effects of water scarcity, as water for drinking supply must be transported from distant distances.
Abstract: Objective: We describe the use of artificial drinking fountains by the Central American agouti (Dasyprocta punctata) in the Calakmul Biosphere Reserve, Mexico. Design/methodology/approach: Eight artificial drinking fountains were monitored each one with a camera trap with the aim to estimate the relative abundance index and activity patterns of visits to the drinking fountains. The monitoring was during the dry season of 2019. The analyzes were carried out with the InfoStat and R programs. Results: From January to May 2019, with a sampling effort of 1121 days/camera, average abundance of 160.0885.44. The pattern of visits to the drinking troughs was mainly diurnal. Limitations/Implications: The water shortage in the Calakmul region limits this monitoring system, as water for drinking supply must be transported from distant distances. Findings/conclusions: The implementation of artificial drinking fountains in the RBC during the dry season was a successful action to mitigate the effects of water scarcity. The use of the water resource by the Central American agouti in artificial drinking fountains was constant, other species of mammals and birds were also observed making use of artificial
