Recent global warming is acting across marine, freshwater, and terrestrial ecosystems to favor species adapted to warmer conditions and/or reduce the abundance of cold-adapted organisms (i.e., "thermophilization" of communities). Lack of community responses to increased temperature, however, has also been reported for several taxa and regions, suggesting that "climatic lags" may be frequent. Here we show that microclimatic effects brought about by forest canopy closure can buffer biotic responses to macroclimate warming, thus explaining an apparent climatic lag. Using data from 1,409 vegetation plots in European and North American temperate forests, each surveyed at least twice over an interval of 12-67 y, we document significant thermophilization of ground-layer plant communities. These changes reflect concurrent declines in species adapted to cooler conditions and increases in species adapted to warmer conditions. However, thermophilization, particularly the increase of warm-adapted species, is attenuated in forests whose canopies have become denser, probably reflecting cooler growing-season ground temperatures via increased shading. As standing stocks of trees have increased in many temperate forests in recent decades, local microclimatic effects may commonly be moderating the impacts of macroclimate warming on forest understories. Conversely, increases in harvesting woody biomass-e.g., for bioenergy-may open forest canopies and accelerate thermophilization of temperate forest biodiversity.
“They Took to the Sea”
(2023)
The sea and maritime spaces have long been neglected in the field of Jewish studies despite their relevance in the context of Jewish religious texts and historical narratives. The images of Noah’s arche, king Salomon’s maritime activities or the miracle of the parting of the Red Sea immediately come into mind, however, only illustrate a few aspects of Jewish maritime activities. Consequently, the relations of Jews and the sea has to be seen in a much broader spatial and temporal framework in order to understand the overall importance of maritime spaces in Jewish history and culture.
Almost sixty years after Samuel Tolkowsky’s pivotal study on maritime Jewish history and culture and the publication of his book “They Took to the Sea” in 1964, this volume of PaRDeS seeks to follow these ideas, revisit Jewish history and culture from different maritime perspectives and shed new light on current research in the field, which brings together Jewish and maritime studies.
The articles in this volume therefore reflect a wide range of topics and illustrate how maritime perspectives can enrich our understanding of Jewish history and culture and its entanglement with the sea – especially in modern times. They study different spaces and examine their embedded narratives and functions. They follow in one way or another the discussions which evolved in the last decades, focused on the importance of spatial dimensions and opened up possibilities for studying the production and construction of spaces, their influences on cultural practices and ideas, as well as structures and changes of social processes. By taking these debates into account, the articles offer new insights into Jewish history and culture by taking us out to “sea” and inviting us to revisit Jewish history and culture from different maritime perspectives.
Ziel der Studie Erfassung der Strukturen zur Frühdiagnostik von Demenzen an Krankenhäusern in Deutschland.
Methodik Fragebogenerhebung.
Ergebnisse 14 % von 1758 kontaktierten Einrichtungen antworteten. 52 % berichteten über ein entsprechendes Angebot, zum großen Teil mit leitlinienorientierten Verfahren, wie Liquordiagnostik. Das Diagnosespektrum umfasste zu 46 % Demenzen und zu 41 % Diagnosen der leichten oder subjektiven kognitiven Störung.
Schlussfolgerung Leitlinienbasierte Diagnostik und Früherkennungskonzepte sind in Gedächtnisambulanzen weitgehend etabliert.
