There is no magic pill. There is no perfect diet. Could it be that our underlying assumption—that what we’re eating is making us fat and sick—is just plain wrong? To address the rapid rise of “lifestyle diseases” like diabetes and heart disease, scientists have conducted a whopping 500,000 studies of diet and another 300,000 of obesity. Journalists have written close to 250 million news articles combined about these topics. Yet nothing seems to halt the epidemic. Anastacia Marx de Salcedo’s Eat Like a Pig, Run Like a Horse looks not just to data-driven science, but to animals and the natural world around us for a new approach. What she finds will transform the national debate abo...

In The Greenland Entomofauna an international team of 64 taxonomic specialists provide for the first time a richly illustrated guide to the identification of the ≈1200 species of Hexapods/Insects, Arachnids and Myriapods so far known to occur in the country. While the composition, origin and adaptations of the Greenland fauna has always been a challenge to biogeographers and ecologists/ecophysiologists, the provision of a tool for detailed identification of its constituent species is now particularly timely, since global climate change will expectedly have a particularly noticeable impact on biota at high latitudes. This obviously renders the feasibility of monitoring distributional range ...
A Cultural History of the Avant-Garde in the Nordic Countries 1925-1950 is the first publication to deal with the avant-garde in the Nordic countries in this period. The essays cover a wide range of avant-garde manifestations: literature, visual arts, theatre, architecture and design, film, radio, body culture and magazines. It is the first major historical work to consider the Nordic avant-garde in a transnational perspective that includes all the arts and to discuss the role of the avant-garde not only within the aesthetic field but in a broader cultural and political context: the pre-war and wartime responses to international developments, the new cultural institutions, sexual politics, the impact of refugees and the new start after the war.
Die heutige Rassehundezucht steckt in einer tiefen Krise: Die durch das Ausstellungswesen praktizierte jahrzehntelange Selektion auf reine Äußerlichkeiten anstatt auf Gesundheit und Vitalität hat zu katastrophalen Konsequenzen geführt. Manche Rassehunde können kaum noch laufen, atmen oder sich auf natürlichem Wege fortpflanzen. Wie das passieren konnte und welche Wege zur Gesundung beschritten werden könnten, zeigt der anerkannte Kynologe Hellmuth Wachtel in diesem Buch. Nach einem kurzen Abriss über Evolution und Domestikation des Hundes unter Einbeziehung der neuesten molekulargenetischen Erkenntnisse geht Wachtel auf die Entstehung der verschiedenen Rassen und schließlich die Schauhundezucht als Erscheinung der Neuzeit ein. Frei von jeder Polemik, aber mit entschiedener Sachlichkeit klärt er über die Ursachen des Niedergangs auf und zeigt machbare Lösungsmöglichkeiten auf.
Most organisms and populations have to cope with hostile environments, threatening their existence. Their ability to respond phenotypically and genetically to these challenges and to evolve adaptive mechanisms is, therefore, crucial. The contributions to this book aim at understanding, from a evolutionary perspective, the impact of stress on biological systems. Scientists, applying different approaches spanning from the molecular and the protein level to individuals, populations and ecosystems, explore how organisms adapt to extreme environments, how stress changes genetic structure and affects life histories, how organisms cope with thermal stress through acclimation, and how environmental and genetic stress induce fluctuating asymmetry, shape selection pressure and cause extinction of populations. Finally, it discusses the role of stress in evolutionary change, from stress induced mutations and selection to speciation and evolution at the geological time scale. The book contains reviews and novel scientific results on the subject. It will be of interest to both researchers and graduate students and may serve as a text for graduate courses.
One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby...
