Book Description
Biodiversity has been a key concept in international conservation since the 1980s, yet historians have paid little attention to its origins. Uncovering its roots in tropical fieldwork and the southward expansion of U.S. empire at the turn of the twentieth century, Megan Raby details how ecologists took advantage of growing U.S. landholdings in the circum-Caribbean by establishing permanent field stations for long-term, basic tropical research. From these outposts of U.S. science, a growing community of American "tropical biologists" developed both the key scientific concepts and the values embedded in the modern discourse of biodiversity. Considering U.S. biological fieldwork from the era of the Spanish-American War through the anticolonial movements of the 1960s and 1970s, this study combines the history of science, environmental history, and the history of U.S.–Caribbean and Latin American relations. In doing so, Raby sheds new light on the origins of contemporary scientific and environmentalist thought and brings to the forefront a surprisingly neglected history of twentieth-century U.S. science and empire.

Book Description
The term biodiversity defines not only all the variety of life in the Earth but also their complex interactions. Under the current scenario of biodiversity loss, and in order to preserve it, it is essential to achieve a deep understanding on all the aspects related to the biological interactions, including their functioning and significance. This volume contains several contributions (nineteen in total) that illustrate the state of the art of the academic research in the field of biological interactions in its widest sense; that is, not only the interactions between living organisms are considered, but also those between living organisms and abiotic elements of the environment as well as those between living organisms and the humans.

Book Description
There is a growing interest in the use of nanoparticles modifiedwith DNAs, viruses, peptides and proteins for the rational designof nanostructured functional materials and their use in biosensorapplications. The challenge is to control the organization ofbiomolecules on nanoparticles while retaining their biologicalactivity as potential chemical and gene therapeutics. Thesenoble metal nanoparticles/biomolecules conjugates have specificproperties and therefore they are attractive materials fornanotechnology in biochemistry and medicine. In this book, the author review work performed dealing with theDNA structure and functionalities, interactions between DNA, noblemetal nanoparticles, surface active agents, solvents and otheradditives. Particular attention is given to how the DNA’schain length and the DNA conformation affect the interaction andstructure of the nanoconjugates and nanostructures that are formed.Also discussed are the recent advances in the preparation,characterization, and applications of noble metal nanoparticlesthat are conjugated with DNA aptamers and oligomers. The advantagesand disadvantages of functionalized nanoparticles through variousdetection modes are highlighted, including colorimetry,fluorescence, electrochemistry, SPR, and, mass spectrometry for thedetection of small molecules and biomolecules. The functionalizednoble metal nanoparticles are selective and sensitive for theanalytes, showing their great potential in biosensing. Furthermore,this book reviews recent progress in the area of DNA-noble metalnanoparticles based artificial nanostructures, that is, thepreparation, collective properties, and applications of variousDNA-based nanostructures are also described.

Book Description
A comprehensive review of the hundreds of bird species that have become extinct over the last 1,000 years of habitat degradation, over-hunting and rat introduction. Extinct Birds has become the standard text on this subject, covering both familiar icons of extinction as well as more obscure birds, some known from just one specimen or from travellers' tales. This second edition is expanded to include dozens of new species, as more are constantly added to the list, either through extinction or through new subfossil discoveries. The book is the result of decades of research into literature and museum drawers, as well as caves and subfossil deposits, which often reveal birds long-gone that disappeared without ever being recorded by scientists while they lived. From Great Auks, Carolina Parakeets and Dodos to the amazing yet almost completely vanished bird radiations of Hawaii and New Zealand via rafts of extinction in the Pacific and elsewhere, this book is both a sumptuous reference and astounding testament to humanity's devastating impact on wildlife.
