Understanding the ecological and behavioral variation of primates is central to improving conservation strategies. Studies of chimpanzees (Pan troglodytes) have shown marked behavioral variability across a wide range of habitats. By comparison, bonobos (Pan paniscus) occur mainly in continuous forest sites, and socioecological models explaining behavioral differences between the two species are based on the assumption that bonobo habitat is richer and more stable than chimpanzee habitats. The objective of this study was to assess bonobo ecology in a forest–savanna mosaic. We specifically explored 1) bonobo home range size, habitat use, and dietary composition; 2) forest fragmentation in a bonobo community’s home range; and 3) seasonality of dietary diversity, habitat use, and spatial distribution. Using 2 years of observational data on location, habitat type, and dietary composition, we found that the bonobo community's home range size, density, and dietary diversity were similar to those observed in continuous forest sites. Bonobos used areas with lower forest fragmentation than the surrounding areas and preferentially spent time in forested habitats. During the dry season, bonobos consumed a lower diversity of fruit species, spent more time in sparse forest with Marantaceae understory, and were closer to the seasonal center of their home range than during the rainy season. Our results contribute to our understanding of behavioral variation in bonobos and suggest that forest–savanna mosaic is valuable to bonobo conservation.

倭黑猩猩(Pan paniscus)栖息地在森林中的时空变化 - 稀树草原马赛克

了解灵长类动物的生态和行为变异是改进保护策略的核心。对黑猩猩(Pan troglodytes)的研究表明,在广泛的栖息地中存在显着的行为变异性。相比之下,倭黑猩猩(Pan paniscus)主要出现在连续的森林地带,解释这两个物种行为差异的社会生态模型是基于倭黑猩猩栖息地比黑猩猩栖息地更丰富和更稳定的假设。这项研究的目的是评估森林 - 稀树草原马赛克中的倭黑猩猩生态。我们专门探讨了 1) 倭黑猩猩家庭范围的大小、栖息地使用和饮食构成;2) 倭黑猩猩社区家庭范围内的森林破碎化;3) 饮食多样性、栖息地利用和空间分布的季节性。使用 2 年的位置观测数据,栖息地类型和饮食组成,我们发现倭黑猩猩群落的家庭范围大小、密度和饮食多样性与在连续森林遗址中观察到的相似。倭黑猩猩使用森林破碎化程度低于周边地区的地区,并优先在森林栖息地中度过。在旱季,倭黑猩猩消耗的水果种类较少,在马兰科林下的稀疏森林中呆的时间更长,并且比雨季更接近其栖息地的季节性中心。我们的研究结果有助于我们了解倭黑猩猩的行为变异,并表明森林 - 稀树草原马赛克对倭黑猩猩保护很有价值。和饮食多样性与在连续林地观察到的相似。倭黑猩猩使用森林破碎化程度低于周边地区的地区,并优先在森林栖息地中度过。在旱季,倭黑猩猩消耗的水果种类较少,在马兰科林下的稀疏森林中呆的时间更长,并且比雨季更接近其栖息地的季节性中心。我们的研究结果有助于我们了解倭黑猩猩的行为变异,并表明森林 - 稀树草原马赛克对倭黑猩猩保护很有价值。和饮食多样性与在连续林地观察到的相似。倭黑猩猩使用森林破碎化程度低于周边地区的地区,并优先在森林栖息地度过。在旱季,倭黑猩猩消耗的水果种类较少,在马兰科林下的稀疏森林中呆的时间更长,并且比雨季更接近其栖息地的季节性中心。我们的研究结果有助于我们了解倭黑猩猩的行为变异,并表明森林-稀树草原马赛克对倭黑猩猩保护很有价值。与雨季相比,它们在具有 Marantaceae 林下植物的稀疏森林中呆的时间更长,并且更接近其栖息地的季节性中心。我们的研究结果有助于我们了解倭黑猩猩的行为变异,并表明森林 - 稀树草原马赛克对倭黑猩猩保护很有价值。与雨季相比,它们在具有 Marantaceae 林下植物的稀疏森林中呆的时间更长,并且更接近其栖息地的季节性中心。我们的研究结果有助于我们了解倭黑猩猩的行为变异,并表明森林-稀树草原马赛克对倭黑猩猩保护很有价值。
