Excerpt from Some Observations Concerning the Botanical Conditions on the Galapagos Islands A few herbaceous halophytes grow on the sand beaches near where we anchored. There was also a low thicket of bushes of Laguncularia racemosa bushes growing here. Other than these no halophytes were found.

Vistas in Botany features the study of life histories of plants, their development from spore or seed through vegetative phases up to the diverse phenomena of reproduction needs. This book is a compilation of studies and research conducted by several botanists that discuss topics such as the taxonomy general principles and Angiosperms; plant biochemistry; causal plant ecology; plant geography; cytology; genes, chromosomes, and evolution; viruses; bacteria; fungi; Bryophyta; Pteridophyta; Gymnospermae; and plant physiology. This publication is valuable to botanical specialists who wish to obtain updated knowledge in botany or phytology, and to students conducting research on the science of plant life.

Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.

In 1905, eight men from the California Academy of Sciences set sail from San Francisco for a scientific collection expedition in the Galapagos Islands, and by the time they were finished in 1906, they had completed one of the most important expeditions in the history of both evolutionary and conservation science. These scientists collected over 78,000 specimens during their time on the islands, validating the work of Charles Darwin and laying the groundwork for foundational evolution texts like Darwin's Finches. Despite its significance, almost nothing has been written on this voyage, lost amongst discussion of Darwin's trip on the Beagle and the writing of David Lack. In Collecting Evolution, author Matthew James finally tells the story of the 1905 Galapagos expedition. James follows these eight young men aboard the Academy to the Galapagos and back, and reveals the reasons behind the groundbreaking success they had. A current Fellow of the California Academy of Sciences, James uses his access to unpublished writings and photographs to provide unprecedented insight into the expedition. We learn the voyagers' personal stories, and how, for all the scientific progress that was made, just as much intense personal drama unfolded on the trip. This book shares a watershed moment in scientific history, crossed with a maritime adventure. There are four tangential suicides and controversies over credit and fame. Collecting Evolution also explores the personal lives and scientific context that preceded this voyage, including what brought Darwin to the Galapagos on the Beagle voyage seventy years earlier. James discusses how these men thought of themselves as collectors before they thought of themselves as scientists, and the implications this had on their approach and their results. In the end, the voyage of the Academy proved to be crucial in the development of evolutionary science as we know it. It is the longest expedition in Galapagos history, and played a critical role in cementing Darwin's legacy. Collecting Evolution brings this extraordinary story of eight scientists and their journey to life.
