The critical agenda for mammalian ecologists over this century is to obtain a synthetic and predictive understanding of the factors that limit the distribution and abundance of mammals on Earth. During the last 100 years, a start has been made on this agenda, but only a start. Most mammal species have been described, but there still are tropical areas of undisclosed species richness. We have been measuring changes in distribution and abundance of many common mammals during the last century, and this monitoring agenda has become more critical as climate change has accelerated and habitat destruction has increased with human population growth. There are a small number of factors that can limit the distribution and abundance of mammals: weather, predation, food supplies, disease, and social behavior. Weather limits distribution and abundance mostly in an indirect manner by affecting food supplies, disease, and predation in the short term and habitat composition and structure in the longer term. A good starting point for all studies of mammals is to define them within a well-structured trophic web, and then quantify the major linkages within that web. We still are far from having data on enough model systems to develop a complete theory and understanding of how food webs are structured and constrained as climate shifts and humans disturb habitats. We have many of the bits and pieces for some of our major ecosystems but a poor understanding of the links and the resilience of our mammalian communities to changes in trophic webs driven by climate change and human disturbances.

哺乳动物生态何去何从?

本世纪哺乳动物生态学家的关键议程是对限制地球上哺乳动物分布和丰度的因素进行综合和预测性的了解。在过去的 100 年里,这个议程已经有了一个开始,但只是一个开始。大多数哺乳动物物种已被描述,但仍有未公开物种丰富度的热带地区。在上个世纪,我们一直在测量许多常见哺乳动物的分布和丰度的变化,随着气候变化的加速和栖息地破坏随着人口的增长而加剧,这一监测议程变得更加重要。有少数因素可以限制哺乳动物的分布和数量:天气、捕食、食物供应、疾病和社会行为。天气主要通过影响短期的食物供应、疾病和捕食以及长期的栖息地组成和结构,以间接方式限制分布和丰度。所有哺乳动物研究的良好起点是在结构良好的营养网中定义它们,然后量化该网中的主要联系。我们还远没有足够的模型系统数据来开发完整的理论和理解食物网如何在气候变化和人类扰乱栖息地时结构和约束。我们拥有一些主要生态系统的许多零碎资料,但对我们的哺乳动物群落与气候变化和人类干扰导致的营养网变化之间的联系和恢复力的了解不足。短期的捕食和长期的栖息地组成和结构。所有哺乳动物研究的良好起点是在结构良好的营养网中定义它们,然后量化该网中的主要联系。我们还远没有足够的模型系统数据来开发完整的理论和理解食物网如何在气候变化和人类扰乱栖息地时结构和约束。我们拥有一些主要生态系统的许多零碎资料,但对我们的哺乳动物群落与气候变化和人类干扰导致的营养网变化之间的联系和恢复力的了解不足。短期的捕食和长期的栖息地组成和结构。所有哺乳动物研究的良好起点是在结构良好的营养网中定义它们,然后量化该网中的主要联系。我们还远没有足够的模型系统数据来开发完整的理论和理解食物网如何在气候变化和人类扰乱栖息地时结构和约束。我们拥有一些主要生态系统的许多零碎资料,但对我们的哺乳动物群落与气候变化和人类干扰导致的营养网变化之间的联系和恢复力的了解不足。然后量化该网络中的主要联系。我们还远没有足够的模型系统数据来开发完整的理论和理解食物网如何在气候变化和人类扰乱栖息地时结构和约束。我们拥有一些主要生态系统的许多零碎资料,但对我们的哺乳动物群落与气候变化和人类干扰导致的营养网变化之间的联系和恢复力的了解不足。然后量化该网络中的主要联系。我们还远没有足够的模型系统数据来开发完整的理论和理解食物网如何在气候变化和人类扰乱栖息地时结构和约束。我们拥有一些主要生态系统的许多零碎资料,但对我们的哺乳动物群落与气候变化和人类干扰导致的营养网变化之间的联系和恢复力的了解不足。
