Book Description
A treasury like no other Since the 1500s, scientists have documented the plants and fungi that grew around them, organizing the specimens into collections. Known as herbaria, these archives helped give rise to botany as its own scientific endeavor. Herbarium is a fascinating enquiry into this unique field of plant biology, exploring how herbaria emerged and have changed over time, who promoted and contributed to them, and why they remain such an important source of data for their new role: understanding how the world’s flora is changing. Barbara Thiers, director of the William and Lynda Steere Herbarium at the New York Botanical Garden, also explains how recent innovations that allow us to see things at both the molecular level and on a global scale can be applied to herbaria specimens, helping us address some of the most critical problems facing the world today. At its heart, Herbarium is a compelling reminder of one of humanity’s better impulses: to save things—not just for ourselves, but for generations to come.

Book Description
Mycology, the study of fungi, originated as a subdiscipline of botany and was a des criptive discipline, largely neglected as an experimental science until the early years of this century. A seminal paper by Blakeslee in 1904 provided evidence for self incompatibility, termed "heterothallism", and stimulated interest in studies related to the control of sexual reproduction in fungi by mating-type specificities. Soon to follow was the demonstration that sexually reproducing fungi exhibit Mendelian inheritance and that it was possible to conduct formal genetic analysis with fungi. The names Burgetf, Kniep and Lindegren are all associated with this early period of fungal genet ics research. These studies and the discovery of penicillin by Fleming, who shared a Nobel Prize in 1945, provided further impetus for experimental research with fungi. Thus began a period of interest in mutation induction and analysis of mutants for biochemical traits. Such fundamental research, conducted largely with Neurospora crassa, led to the one gene: one enzyme hypothesis and to a second Nobel Prize for fungal research awarded to Beadle and Tatum in 1958. Fundamental research in biochemical genetics was extended to other fungi, especially to Saccharomyces cerevisiae, and by the mid-1960s fungal systems were much favored for studies in eukaryotic molecular biology and were soon able to compete with bacterial systems in the molecular arena.

Book Description
Biological collections are a critical part of the nation's science and innovation infrastructure and a fundamental resource for understanding the natural world. Biological collections underpin basic science discoveries as well as deepen our understanding of many challenges such as global change, biodiversity loss, sustainable food production, ecosystem conservation, and improving human health and security. They are important resources for education, both in formal training for the science and technology workforce, and in informal learning through schools, citizen science programs, and adult learning. However, the sustainability of biological collections is under threat. Without enhanced strategic leadership and investments in their infrastructure and growth many biological collections could be lost. Biological Collections: Ensuring Critical Research and Education for the 21st Century recommends approaches for biological collections to develop long-term financial sustainability, advance digitization, recruit and support a diverse workforce, and upgrade and maintain a robust physical infrastructure in order to continue serving science and society. The aim of the report is to stimulate a national discussion regarding the goals and strategies needed to ensure that U.S. biological collections not only thrive but continue to grow throughout the 21st century and beyond.

Book Description
The intriguing Bird’s Nest Fungi (Nidulariaceae) of forest, meadow, and garden have been familiar to botanists since 1601, but only relatively recently has the significance of their peculiar form been realized. Dr Brodie traces the long controversy that arose when Bird’s Nest Fungi were first classified as seed plants because of the numerous seed-like bodies contained in their small cup-shaped fruit bodies. The ‘seeds’ are now known to contain spores like those of other fungi such as puffballs, to which the Nidulariaceae are related. Present-day research has shown that certain Bird’s Nest Fungi produce chemicals having previously unrecognized molecular structure. Between these milestones Dr Brodie reveals the solution to the mystery of the dispersal of the ‘eggs’ from the ‘bird’s nest’: the fruit bodies are splash guns from which the reproductive spores are ejected by the force of falling raindrops. This explanation of the phenomenon is supported by copious observations and hitherto unpublished experiments. All known species of Nidulariaceae, including many only recently recognized, are described in this volume. All aspects of growth, structure, development, and life-cycle of these fungi, both in nature and in laboratory culture, are reported in a modern, comprehensive treatment of a subject which is of interest not only to mycologists but to amateur naturalists as well.
