The influence of other factors is also discussed. Because the two study areas are at about the same latitude, we suggest that the behavioral plasticity is due to different temperature regimes associated with a local effect of altitude and topography of the terrain on the incidence of solar rays inside the forest. The difference between activity patterns in the two locations suggests plasticity in agouti behavior. 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. Universidade Vila Velha, Programa de Pós-Graduação em Ecologia de Ecossistemasĭasyproctidae, abiotic factors, activity patterns, circadian rhythm, photoperiod AbstractĪbstract 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.
