This guide describes and illustrates in full color the plants and animals that live in or near ponds, lakes, streams, and wetlands. It includes surface-dwelling creatures as well as those of open water, the bottom, and the shore and tells how various animals and plants live together in a community. As well, it provides suggestions for:

· Where and when to look

· Observing and collecting specimens

· Making exciting discoveries

There is now an increased awareness of the importance of polar regions in the Earth system, as well as their vulnerability to anthropogenic derived change, including of course global climate change. This new edition offers a concise but comprehensive introduction to polar ecology and has been thoroughly revised and updated throughout, providing expanded coverage of marine ecosystems and the impact of humans. It incorporates a detailed comparison of the Arctic and Antarctic systems, with a particular emphasis on the effects of climate change, and describes marine, freshwater, glacial, and terrestrial habitats. This breadth of coverage is unique in the polar biology literature. As with other titles in the Biology of Habitats Series, particular emphasis is placed on the organisms that dominate these extreme environments although pollution, conservation and experimental aspects are also considered. This accessible text is suitable for both senior undergraduate and graduate students taking courses in polar ecology, often as part of a wider marine biology degree programme. It will also be of value and use to the many professional ecologists and conservation biologists requiring a concise overview of the topic.

Placed uniquely at the intersection of common law and civil law, mixed legal systems are today attracting the attention both of scholars of comparative law, and of those concerned with the development of a European private law. Pre-eminent among the mixed legal systems are those of Scotland and South Africa. In South Africa the Roman-Dutch law, brought to the Cape by the Dutch East India Company in 1652 was, from the early nineteenth century onwards, infused with and remoulded by the common law of the British imperial master. In Scotland a more gradual and elusive process saw the Roman-Scots law of the early period fall under the influence of English law after the Act of Union in 1707. The result, in each case, was a system of law which drew from both of the great European traditions whilst containing distinctive elements of its own. This volume sets out to compare the effects of this historical development by assessing whether shared experience has led to shared law. Key topics from the law of property and obligations are examined, collaboratively and comparatively, by teams of leading experts from both jurisdictions. The individual chapters reveal an intricate pattern of similarity and difference, enabling courts and legal writers in Scotland and South Africa to learn from the experience of a kindred jurisdiction. They also, in a number of areas, reveal an emerging and distinctive jurisprudence of mixed systems, and thus suggest viable answers to some of the great questions which must be answered on the path towards a European private law.

Unmanned aircraft systems (UASs) have played an important role in warfare over the past two decades, including to conduct counterterrorism operations. To better understand the utility of UASs, this latest report from CSIS adopts a comparative case study approach and examines the Nagorno-Karabakh war in 2020, Ukraine war in 2022, and Northern Edge-21 exercise in the Indo-Pacific in 2021. These cases demonstrate that UASs have been increasingly integrated into combined arms warfare, a major change from the past. In addition, UASs are likely to play an increasingly important role in several types of missions as part of strategic competition and warfare with such countries as China and Russia.
