The Parque Estadual do Prosa (PEP), in Campo Grande, MS, is an urban fragment of savanna (cerrado) and tall savanna woodland (cerradão), with an area of 1,335 km(2), where the population density of brown-nosed coatis is 33.71 individuals/km(2). Our results suggest that seasonality at the PEP causes changes in the availability of resources for coatis, altering their home range areas, their dispersion patterns and their daily behaviour. And our observations regarding male-band associations, agonistic interactions between bands and their daily behaviour emphasize the plasticity of coati social structure, and its potential for future comparative studies.
位于巴西马托格罗索州大坎普市的普罗萨州立公园（PEP）是一片稀树草原（塞拉多）和高大稀树草原林地（大塞拉多）的城市区域，面积为1335平方千米，其中长鼻浣熊的种群密度为每平方千米33.71只。我们的研究结果表明，普罗萨州立公园的季节性变化导致了浣熊可获取资源的变化，改变了它们的家域面积、扩散模式和日常行为。我们对雄性群体关联、群体间的争斗互动及其日常行为的观察强调了浣熊社会结构的可塑性，以及其在未来比较研究中的潜力。
