Conservation of carnivores involves finding solutions to minimize habitat loss and human-wildlife conflict. Understanding the nature of land-use economics can allow us to mitigate both threats. In the Pantanal, the two main economic activities are cattle ranching and ecotourism, each of which directly and indirectly affect the persistence of jaguars (Panthera onca). To understand how the geography of these economic activities is related to jaguar populations, we developed a jaguar distribution model (JDM), livestock density model, and ecotourism lodge density model for the Pantanal. Due to the recent wildfires within the Pantanal, we also assess the impact of burnt areas that are suitable for jaguars, cattle ranching, and tourism. Our JDM indicate that 64% of the Pantanal holds suitable habitat for jaguars. However, jaguar habitat suitability was positively correlated with ecotourism, but negatively correlated with areas most suitable for intensive cattle-ranching. This demonstrates a biome-wide scenario compatible with jaguar conservation. Of particular concern, recent wildfires overlap most suitable areas for jaguars. If wildfires become increasingly frequent, this would represent a serious threat to jaguars and many other wildlife populations. We emphasize the global importance of the Pantanal wetland ecoregion as a key stronghold for long-term jaguar conservation.
保护肉食动物需要寻找解决方案,以尽量减少栖息地的丧失和人与野生动物的冲突。了解土地利用经济学的性质可以使我们减轻这两种威胁。在潘塔纳尔湿地,两种主要的经济活动是养牛业和生态旅游业,这两种活动都直接和间接地影响着美洲虎(Panthera onca)的生存。为了了解这些经济活动的地理分布与美洲虎种群之间的关系,我们为潘塔纳尔湿地开发了美洲虎分布模型(JDM)、牲畜密度模型和生态旅游小屋密度模型。由于潘塔纳尔湿地最近发生了野火,我们还评估了适合美洲虎、养牛业和旅游业的燃烧区的影响。我们的 JDM 表明,潘塔纳尔湿地的 64% 拥有适合美洲虎的栖息地。然而,美洲虎的栖息地适宜性与生态旅游呈正相关,与最适合集约化养牛的地区呈负相关。这展示了一个与保护美洲虎相兼容的生物群落范围的情景。特别令人关注的是,最近的野火与最适合美洲虎的地区重叠。如果野火变得越来越频繁,这将对美洲虎和许多其他野生动物种群构成严重威胁。我们强调潘塔纳尔湿地生态区作为长期保护美洲虎的关键据点的全球重要性。
