Dan Perry was born and raised on Mount Carmel. From childhood, encouraged by his father, he often wandered on the mountain, getting to know its surroundings and connecting with its flora and fauna. As an adult, he became involved in the newly formed Nature Conservation Authority - first as a tour guide, and later as part of the Society for the Protection of Nature. In 1965 he started working within the Nature Conservation Authority, established in 1964, as an inspector in the Galilee as part of a collaboration between the Society and the Authority. Immediately after the Six-Day War, he established a magnificent system of nature reserves on the Golan Heights. He ran the Hermon Development Authority which established the Hermon site, and then joined the Authority's management and held a variety of positions. This unique volume includes color photographs.

Although frequently observed in natural habitats across Israel, the true nature of the "strange growths" (galls) that appear on various plants is not always clear. Insect-induced plant galls are actually the most intimate way in which animals feed on plants. This book reveals to naturalists and scientists one of the most impressive and conspicuous groups among gall-forming insects: aphids that form galls on wild pistachio (Pistacia). The gall serves as an incubator for the aphids, providing them with a rich food supply and shelter from natural enemies and abiotic factors. Several aphid generations develop in galls from spring to fall. During these months, the gall functions as a dynamic and complex multitrophic ecological (mini) system, including pathogens, competitors, parasites, and predators. The first part of the book describes the multi-disciplinary information on the biology and ecology of the aphids and gall system from molecular, anatomical, physiological, biochemical, behavioral, biogeographic, and evolutionary points of view. The second part of the book is in fact an informative and photographic guide to all the aphid-induced galls on wild pistachios in Israel.

In the second half of the twentieth century, the medical community adopted the scientific method as a basis for practice. It seemed that after thousands of years the way was paved for a regulated process: from the laboratory through the clinical trial to the patient's bed. But it soon became clear that the road is neither straight nor continuous. Clinical research only offers unequivocal answers in a few cases. The balance between benefit and risk does not end with a statistical calculation; A significant part of the consideration of the factors that determine the change of medical practice is based on values, worldview and interests. Many factors are involved in the path leading from the laboratory to the patient: scientists, doctors, pharmaceutical and technology companies, politicians, regulators, and at the end of the path stand the patients themselves. Each of these factors uses the means at its disposal to influence the final result - the diagnosis, treatment and follow-up of the patient. The path of progress from the laboratory to the patient is also not continuous: sometimes the intervals between steps are large, sometimes sudden jumps occur after a prolonged period of slowing down and even stopping. Scientific and clinical research depends on the initiative, skills and determination of the researchers, and not a little on coincidences and has no fixed timetables. This book is dedicated to revealing the evolution of medical practice, to identifying fundamental changes in practice and to describing the winding way in which they were accepted and assimilated into the body of medical knowledge and the mutual relationship between the doctor and the patient.

The migration of birds is a fascinating phenomenon that has aroused curiosity since ancient times. This book brings to the interested reader the latest knowledge collected on this phenomenon by many researchers - scientists and enthusiasts, in Israel and around the world, and also presents the importance of the Land of Israel as a major traffic route for birds that migrate from Europe and Asia to Africa and back again. Recognizing this importance also has implications for preserving nature in the country.

Korot is devoted to the study of the philosophical, sociological and ethical aspects of the history of medicine and Judaism. The topics covered by the journal include: medicine in Jewish and Hebrew sources, the history of Jewish physicians, medicine in Palestine and Israel and medicine during the Nazi period. Each volume contains mostly English-language articles, together with some Hebrew contributions (abstracted in English). The "Historical Notes" and "Notes and Events" sections cover recent important developments and events in the above mentioned topics around the world. Each issue also includes several reviews of noteworthy books and contributions to the field.

In October 2018, results of a randomized controlled trial showed an excess mortality mainly from cancer, among “healthy” people over the age of 70 who took aspirin, in contrast to many clinical studies previously published. This event was another record in the crisis in scientific medicine that has been unfolding before our eyes in recent decades. In this book the author tries to trace the causes of the shocks that afflict the medical knowledge base, and to offer solutions to strengthen and stabilize it. This book includes four parts. The first part discusses aspirin as a test case for development of clinical research. The second part is devoted to a discussion of the seven foundations of modern clinical research while revealing the pros and cons of each and their relative contribution to the pursuit of scientific truth. In the third part, five groundbreaking discoveries are examined. In each of them, the process that led to the discovery is deciphered, emphasizing the findings making clinical research, on the way from bench to bedside, redundant. In the fourth part the author exposes the rules of the competition among scientist, and determines its impact on the conduct of research and its results.

This book describes the increasing interactions between wildlife and people in human settlements in Israel and beyond.

There over 1,300 species of bats in the world, which constitute one-third of the total sum of mammals in Israel. Most people are not aware of them and their fantastic ways of living, because contrary to other mammals, bats do not walk or swim (although they are capable of doing both), but rather fly actively. They are also nocturnal, and unlike most mammals and birds their main sense is not sight but hearing. In order to find their way around, bats omit calls and listen to the echoes they produce in order to navigate. This is also how they find their prey, which is comprised of a variety of animals such as insects, scorpions, fish, frogs, and toads, as well as nectar and fruit. Each species of bats has a special diet and unique behavioural , anatomical and physiological adaptations for this purpose. Bats are beneficial to people by pollinating flowers of many plants, consuming enormous quantities of insects that spread malaria and damage agricultural crops and producing valuable fertilizer-guano. In spite of these benefits, people around the world have created many superstitious beliefs and legends about bats and their behavior. This book describes the biology of bats and their complex relationships with humanity.
