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.

The spread of the Assyrian Empire over the entire Fertile Crescent in the second half of the 8th century BC introduced various forms of cooperation between the neighboring nomadic Arabs and the imperial authorities. The geographical conditions and resultant lifestyle of the Arabs facilitated a mutual dependence and delicate equilibrium between themselves and the Assyrian rulers, eager to capitalize on their unprecedented regional might. Henceforth, the Arabs appear as an organic component of the Fertile Crescent history rather than mere desert raiders.

The book deals with geomorphological and soil aspects, plants, and animals (arthropods, reptiles, and rodents) of dunes on the coastal plain of Israel. The book has 11 chapters: structure and geomorphological processes of coastal dunes, soil formation processes, the characteristic of the largest coastal dune areas, flora and fauna (arthropods, reptiles, small mammals: rodents), the impact of man and climate changes on coastal dune ecosystems, ecological-economic losses due to the loss or fixation of coastal dunes, policy, planning, and conflicts between stakeholders, conservation and interface of coastal dunes. The book is a product of the vast knowledge accumulated over decades in detailed studies conducted by Prof. Pua Bar, together with many other researchers in the coastal dunes in Israel.

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 his autobiography, Abraham Halevi Fraenkel describes growing up as an Orthodox Jew in Germany and his development as a mathematician at the beginning of the twentieth century. In his memoir, originally published in German in 1967, Fraenkel painted a unique picture of the complexity of Jewish life in Germany with special emphasis on the developments in the Orthodox community. He described the world of mathematics in Germany in the first half of the twentieth century, in the context of the great mathematicians he met, many of whom were Jews or had Jewish roots. In his personal life, Fraenkel merged the worlds of orthodox Judaism, liberal Zionism and mathematics, in a period of global and national upheavals, which included the two World Wars and the establishment of the State of Israel. The last chapter of the book, which describes his extensive public activity in Israel from the 1930s until his death in 1965, was written by Prof. Jiska Cohen-Mansfield. Introductions were added by Prof. Yehoshua Bar-Hillel and Prof. Menachem Magidor, the former president of the Hebrew University.

This book describes the changes that occurred in the mammalian fauna of the Land of Israel during the Pleistocene.

If a large rock had collapsed in a desert or a tree had fallen in the heart of a distant forest several hundred miles away from living beings, would it have made a sound upon its fall? Different people will give different answers to this ancient question. Objectively, some will say that a sound would have been heard because sound does not exist only in the mind of the listener. Subjectively, some would say that a sound requires someone to listen to it. What is correct? Is this complex answer related to the essence of sound? It's All in the Sound investigates the phenomenon of sound and tries to understand it and answer, among other things, the above questions. It was written to meet the needs of students and teachers, with a desire to update the teaching of physics and fill the shortage of textbooks in this field, which is associated with teaching the subject of sound waves. The gradual development of the concept of sound is discussed in the book by building structured experimental illustrations, as well as mathematical expressions describing this miraculous phenomenon. The illustrations were chosen so that a curious reader could repeat most of the experiments in a home environment without the need for special laboratory equipment. Even for readers unfamiliar with the basics of physical mathematics that describe sound, this book may provide a unique experience and open up a new window to understanding physics.

Today, the term "natural reserve" is common in Israel. However, this wasn’t the case during the first years of its existence. A majority of the planning authorities did not understand what natural reserves were and why they were required, and the Hebrew language did not yet have a term for them. A small group of nature lovers struggled to preserve nature, leading battels, some of which continue to this day. The results of some of the successful battles can be seen across Israel today – in natural reserves, national parks and fields of wildflowers. The history of these battles is brought forth in this book by Dr. Uzi Paz, one of the pioneers of nature preservation in Israel. He also unfolds the changes formed in the country's landscape, flora and fauna, from ancient times to this day. The book contains a wealth of photographs taken by the author.
