虽然人类景观中剩余的自然生境的保护作用是明确的，但农业基质对动物使用的限制程度尚不清楚，但对于评估物种对土地使用变化的适应力至关重要。使用占用框架，我们评估了油棕种植园如何影响哥伦比亚Llanos陆地哺乳动物的发生和栖息地利用。此外，我们评估了林下植被和接近森林对种植园内栖息地利用的影响。大多数物种在整个研究区域表现出有限的分布，特别是在油棕种植园。栖息地类型强烈影响栖息地使用的12个更广泛分布的物种与油棕榈负面影响物种，如水豚和裸尾犰狳。其余物种没有表现出明显的影响，生境类型，但油棕和森林利用的概率不同物种。总体而言，多面手mesocarnivores，白尾鹿和巨型食蚁兽更有可能使用油棕，而其余的物种，包括虎猫和较小的食蚁兽，表现出对森林的偏好。距离最近的森林物种栖息地的使用有混合的影响，而林下植被促进使用油棕物种的存在。我们的研究结果表明，允许林下植被内种植园和维护附近的河岸走廊将增加陆生哺乳动物的可能性内油棕景观的发生。
While the conservation role of remaining natural habitats in anthropogenic landscapes is clear, the degree to which agricultural matrices impose limitations to animal use is not well understood, but vital to assess species’ resilience to land use change. Using an occupancy framework, we evaluated how oil palm plantations affect the occurrence and habitat use of terrestrial mammals in the Colombian Llanos. Further, we evaluated the effect of undergrowth vegetation and proximity to forest on habitat use within plantations. Most species exhibited restricted distributions across the study area, especially in oil palm plantations. Habitat type strongly influenced habitat use of four of the 12 more widely distributed species with oil palm negatively affecting species such as capybara and naked-tailed armadillo. The remaining species showed no apparent effect of habitat type, but oil palm and forest use probabilities varied among species. Overall, generalist mesocarnivores, white-tailed deer, and giant anteater were more likely to use oil palm while the remaining species, including ocelot and lesser anteater, showed preferences for forest. Distance to nearest forest had mixed effects on species habitat use, while understory vegetation facilitated the presence of species using oil palm. Our findings suggest that allowing undergrowth vegetation inside plantations and maintaining nearby riparian corridors would increase the likelihood of terrestrial mammals’ occurrence within oil palm landscapes.
