项目摘要

Habitat loss is the greatest cause of biodiversity loss, as it isolates small patches of habitat along with the populations in these fragments. This project examines landscape connectivity, which is the inverse of fragmentation, and the degree to which corridors among fragments facilitate the movement of organisms and thus alleviate the effects of fragmentation. Although habitat connectivity is considered to be fundamental to the maintenance of species diversity, there is remarkably little empirical evidence documenting the effects of corridors. The investigators will extend an ongoing experiment explicitly designed to test the effects of habitat connectivity. Results to date show that species diversity increases when fragments are connected by corridors, but the question remains whether these responses are short-term or persistent. The project will generate long-term data to resolve the mechanisms underlying the relationship between connectivity, diversity, and time, and to determine whether connectivity effects are long-lasting or transient. This experiment provides a direct link to conservation by manipulating connectivity through landscape corridors. Strategies to reconnect landscapes through landscape corridors have dominated land acquisitions in conservation. Results of this project will provide some of the first evidence for land managers of the value of landscape connections for protecting biological diversity. The project will develop a solutions-oriented workshop with scientists and land managers to catalyze the translation of science to practical long-term land conservation in the southeastern United States study region. A website dedicated to bridging the science and practice of conservation corridors will contribute to these efforts. Both graduate and undergraduate students will be engaged in and trained through participation in the research, continuing a successful collaboration with the US Forest Service to train and mentor women and students from underrepresented groups.

栖息地丧失是生物多样性丧失的最大原因，因为它将小片栖息地与这些碎片中的种群隔离开来。该项目审查了景观连通性，这是碎片化的反面，以及碎片之间的走廊在多大程度上促进了生物体的移动，从而减轻了碎片化的影响。尽管生境连通性被认为是维持物种多样性的基础，但记录走廊影响的经验证据非常少。研究人员将延长一项正在进行的实验，该实验明确旨在测试栖息地连通性的影响。迄今为止的结果表明，当碎片通过走廊连接时，物种多样性增加，但问题仍然是这些反应是短期的还是持久的。该项目将生成长期数据，以解决连通性、多样性和时间之间关系的潜在机制，并确定连通性影响是长期的还是短暂的。这项实验通过操纵景观走廊的连通性，提供了与保护的直接联系。通过景观走廊重新连接景观的战略在保护土地收购中占据主导地位。该项目的结果将为土地管理者提供一些最早的证据，证明景观连接对保护生物多样性的价值。该项目将与科学家和土地管理人员共同举办一个以解决方案为导向的讲习班，以促进将科学转化为美国东南部研究区域长期土地保护的实际做法。一个致力于将保护走廊的科学和实践联系起来的网站将为这些努力做出贡献。研究生和本科生都将通过参与这项研究来参与和培训，继续与美国林务局成功合作，培训和指导来自代表性不足群体的妇女和学生。
