The winegrowers dig pits and plant the vines in the lapillus coat, as it is known, which is several meters thick. In the dry climate on Lanzarote, the porous stones which form the layer, and which are no bigger than a pea or a nut, store the night dew. The plants are protected from strong wind by low walls. This is an example of how agriculture can adapt to extreme conditions. Max Planck Research · 1 | 2021 EDITORIAL Dear reader, Our planet provides a comfortable home for the life it supports. With its water, food, warmth and light, it has everything that all kinds of organisms – including humans – need to grow and thrive. However, at certain times and places, conditions on Earth can be distinctly hostile. Heat or cold, heavy precipitation or total drought, strong winds, lightning, volcanic eruptions and earthquakes all threaten the existence of many living beings. The only way they can survive is by adapting to such extremes. Nature is constantly providing new and surprising examples of this, such as a species of algae that is indigenous to the desert. Researchers are studying how these algae can survive in such inhospitable environments and whether its properties could be 3 transferred to crop plants. The question of how plants can cope with drought is becoming ever more urgent. Recent summers have shown that the agricultural industry needs to be prepared for long periods of drought, even in this country. Moreover, climate research models have shown that extreme weather events will become even more common in the future. Forecasting them can help us adjust to these situations. History has shown that humans respond to the challenges posed by their environment in many different ways. Disasters such as earthquakes and volcanic eruptions have caused great human tragedies, but they have also influenced and inspired art and culture. There are many examples of this in the Italian city of Naples. Extremes are threatening. However, we have seen new life burgeon and new opportunities open up again and again, even in inhospitable surroundings and harsh conditions. With this in mind, we hope you will find this magazine informative reading!

As a joint development of the Max Planck Institute for Biogeochemistry in Jena and the Technical University of Ilmenau, the underlying algorithm was first trained with several million images of plants. Now, it learns new data every time it is used. So why not download the Flora Incognita app, take a photo and find out what plants are currently in bloom all PHOTO: SHUTTERSTOCK/LAPA SMILE SHUTTERSTOCK/LAPA PHOTO: around you? And not only that, the app can do so much more. Is this plant poisonous? Is it rare or common? Is it a protected species? Flora Incognita offers users quick, on-site access to a great deal of knowledge about unfamiliar plants. At the same time, scientists obtain new data and facts about plant diversity. When do certain species flower, and where? How much do plants from a single species differ from each other? How does the composition of plant species change at a particular loca- tion? With this Citizen Science project, anyone can help to investigate biodiversity and how it is changing, for example through climate change or agriculture. And with a little help of artificial intelligence, a wildflower meadow – here in the Bavarian Alps – becomes a research location. floraincognita.com Max Planck Research · 1 | 2021 Relics of Late Antique prosperity: the Late Antique Little Ice Age in the 6th century A.D. saw settlements in the Near East, like this one in Syria, expand as a result of increasing precipita- tion and improved water management.

BARKER UNIVERSITY OF WISCONSIN-MADISON. U.S.A. Abstract: The uses of matrimony have always been standard practices for dynastic advancement through the ages. A perfect case study involves two important Italian families whose machinations had local implications and widespread international extensions. Their competitions are given particular point by the fact that one of the two families, the House of Savoy, was destined to become the dynasty around which the Modern State of Italy was created. This essay is, in part, a study in dynastic genealogies. But it is also a reminder of the wide impact of the crusading movements, beyond military operations and the creation of ephemeral Latin States in the Holy Land. Keywords: Matrimony, Crusading, Montferrat, Savoy, Levant.

  • Appendix for “The Feudal Revolution and Europe's Rise: Political
    Appendix for “The Feudal Revolution and Europe’s Rise: Political Divergence of the Christian West and the Muslim World before 1500 CE” August 1, 2012 1 Feudalism and Political Stability To formalize the intuition presented in Section 3.3 using a simple framework, suppose that a perfectly myopic, risk-neutral sovereign imperfectly controls a polity that creates output of size one each period. Denote by γ the amount of land controlled by the military regardless of the actions of the sovereign (this can be interpreted as the percentage of the entire polity controlled by the military). Suppose that there are N perfectly myopic, risk-neutral members of the military (where N is sufficiently large) and that γ is evenly distributed between the members of this class. We consider the parameter value γ exogenously given. A value of γ = 0 corresponds to a perfectly absolutist sovereign (who uses mamluks or mercenaries to staff his military) whereas higher values of γ denote more feudal arrangements. Note that our assumption of perfectly myopic agents allows us to abstract from the potentially important issue of how the sovereign compensates the military (i.e., iqta’ rents versus land grants).1 In addition, we abstract from other important issues in order to focus on the sovereign’s desire to prevent a successful revolt. We do so in order to highlight one mechanism that we believe contributes to the observed increase in ruler duration. The order of play in the game is as follows: after observing γ the sovereign moves first and decides whether to keep the entire amount of output he controls to himself or whether to divide it equally between himself and the military.

  • Mediating Public Science: Experts, Politics, and Climate Change in the News Media in Canada
    MEDIATING PUBLIC SCIENCE: EXPERTS, POLITICS, AND CLIMATE CHANGE IN THE NEWS MEDIA IN CANADA BERNHARD ISOPP A DISSERTATION SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY GRADUATE PROGRAM IN SCIENCE AND TECHNOLOGY STUDIES YORK UNIVERSITY TORONTO, ONTARIO October 2018 © Bernhard Isopp, 2018 Abstract This project offers a reconstructionist science and technology studies (STS) analysis of climate change coverage in three Canadian newspapers, the Globe and Mail, the National Post, and the Toronto Star from 2006 to 2013. It employs a combination of framing, critical discourse, and philosophical analyses to address two core questions: (1) Why has climate change been represented in these newspapers in the ways it has? (2) What effects have these newspapers had in shaping issues of climate change? These broad inquiries are organised by a set of six more specific conceptual concerns stemming from STS: i) How do scientists relate, engage, and compete with other actors in influencing climate change coverage? ii) To what extent can these newspapers be understood as a site of scientific practice, communication, and knowledge production? iii) What broader social, political, and economic factors are linked to the competing representations of climate change and actor coalitions that emerge in these newspapers? iv) What broader images, ideologies, and philosophies of science and scientists shape and emerge from these media discourses? v) What do STS conceptions of scientific rhetoric suggest about these discourses? vi) How is the authority of science and scientists established, affected, challenged, and undermined through and by all these interacting influences and processes? While the answers to these questions are multifaceted, the authority of science is a culminating theme.
