原始栖息地通常被认为是野生动物保护最重要的生态资源，但由于人类活动造成的森林退化，次生林的马赛克现象日益突出。我们研究了马赛克热带森林中的三种森林类型，包括矮的次生林（SS）、高的次生林（TS）和淡水沼泽森林（SF）。这些森林的林分结构和植物区系组成以及果实、花朵和嫩叶的物候生产力各不相同。我们研究了长尾猕猴（Macaca fasciculis）的栖息地利用与物候活动指数的关系。与 TS 和 SF 相比，猕猴更多地使用 SS 来进食/觅食。这是因为 SS 的水果产量较高，而水果是猕猴首选的食物资源。 SS和TS幼叶的茎密度也影响栖息地利用，因为它们提供了更多的丛生资源。 SF 的利用有限，但这些森林提供了更多物种丰富的资源。我们的结果表明，M.束状对异质镶嵌森林中发现的森林类型之间物候活动的小规模变异做出反应，年轻的次生再生森林可能提供最重要的食物资源。马赛克景观可能很重要，因为它们可以缓冲任何特定森林类型中食物资源时间变化的影响。在我们日益受到人类影响的景观中，更好地了解次生森林马赛克的作用对于野生动物栖息地及其赖以生存的动物的保护和管理至关重要。
Pristine habitats have generally been considered to be the most important ecological resource for wildlife conservation, but due to forest degradation caused by human activities, mosaics of secondary forests have become increasingly prominent. We studied three forest types in a mosaic tropical forest consisting of short secondary forest (SS), tall secondary forest (TS) and freshwater swamp forest (SF). These forests differed in stand structure and floristic composition, as well as phenological productivity of fruits, flowers and young leaves. We examined habitat use of long-tailed macaques (Macaca fascicularis) in relation to indices of phenological activity. The macaques used the SS for feeding/foraging more than the TS and the SF. This was because the SS had higher productivity of fruit, which is a preferred food resource for macaques. Stem densities of young leaves in the SS and the TS also influenced habitat use, as they provided more clumped resources. Use of SF was limited, but these forests provided more species-rich resources. Our results showed thatM. fascicularisresponded to small-scale variability in phenological activity between forest types found in a heterogeneous mosaic forest, with young secondary regrowth forests likely providing the most important food resources. Mosaic landscapes may be important as they can buffer the effects of temporal food resource variability in any given forest type. In our increasingly human-altered landscapes, a better understanding of the role of secondary forest mosaics is crucial to the conservation and management of wildlife habitats and the animals they support.
