Remote detection of invasive alien species

The spread of invasive alien species (IAS) is recognized as the most severe threat to biodiversity outside of climate change and anthropogenic habitat destruction. IAS negatively impact ecosystems, local economies, and residents. They are especially problematic because once established, they give rise to positive feedbacks, increasing the likelihood of further invasions and spread. The integration of remote sensing (RS) to the study of invasion, in addition to contributing to our understanding of invasion processes and impacts to biodiversity, has enabled managers to monitor invasions and predict the spread of IAS, thus supporting biodiversity conservation and management action. This chapter focuses on RS capabilities to detect and monitor invasive plant species across terrestrial, riparian, aquatic, and human-modified ecosystems. All of these environments have unique species assemblages and their own optimal methodology for effective detection and mapping, which we discuss in detail

White House publicity operations during the Korean War, June 1950 – June 1951

Truman was the first modern president to face the challenge of selling a limited war. Based on a wide range of primary sources, this article explores the impact that the Korean War had on Truman’s publicity operations. Whereas all wars place important new demands on presidents to speak out more frequently and forcefully, limited wars place significant constraints on what presidents can say and do. During the Korean War, Truman refused to go public at key moments, often employed rhetoric that was more restrained than at earlier moments of the Cold War, and shied away from creating new structures to coordinate the official message. Such actions also had important consequences. In 1950-51, they hampered the task of effective presidential communication, and contributed to the war’s growing unpopularity. For the longer term, they demonstrated the difficulties of selling a limited war, and hence place into sharper context the problems that beset Truman’s successors during the subsequent conflict in Vietnam
