Zoonotic host diversity increases in human-dominated ecosystems | Nature - 0 views

  •  
    Land use change-for example, the conversion of natural habitats to agricultural or urban ecosystems-is widely recognized to influence the risk and emergence of zoonotic disease in humans1,2. However, whether such changes in risk are underpinned by predictable ecological changes remains unclear. It has been suggested that habitat disturbance might cause predictable changes in the local diversity and taxonomic composition of potential reservoir hosts, owing to systematic, trait-mediated differences in species resilience to human pressures3,4. Here we analyse 6,801 ecological assemblages and 376 host species worldwide, controlling for research effort, and show that land use has global and systematic effects on local zoonotic host communities. Known wildlife hosts of human-shared pathogens and parasites overall comprise a greater proportion of local species richness (18-72% higher) and total abundance (21-144% higher) in sites under substantial human use (secondary, agricultural and urban ecosystems) compared with nearby undisturbed habitats. The magnitude of this effect varies taxonomically and is strongest for rodent, bat and passerine bird zoonotic host species, which may be one factor that underpins the global importance of these taxa as zoonotic reservoirs. We further show that mammal species that harbour more pathogens overall (either human-shared or non-human-shared) are more likely to occur in human-managed ecosystems, suggesting that these trends may be mediated by ecological or life-history traits that influence both host status and tolerance to human disturbance5,6. Our results suggest that global changes in the mode and the intensity of land use are creating expanding hazardous interfaces between people, livestock and wildlife reservoirs of zoonotic disease.

Rethinking 'tipping points' in ecosystems and beyond - 0 views

  •  
    Until now, research into regime shifts has focused on critical environmental thresholds, or "tipping points," in external conditions-eg when crossing a certain temperature threshold triggers a sudden shift to desertification. But the new model by Catalina Chaparro-Pedraza and SFI External Professor André de Roos, both at the University of Amsterdam, reveals how a small change in the external environment, with little immediate impact, can induce slow evolutionary changes in the species that inhabit the system. After what the researchers call a "considerable delay," wherein species slowly evolve a new trait or behavior over generations, the regime shift manifests as a delayed reaction.

Research could save years of breeding for new Miscanthus hybrids - 0 views

  •  
    Breeders have been working to develop new Miscanthus hybrids for years, but the clonal crop's sterility, complex genome, and long time to maturity make conventional breeding difficult. In a new study, University of Illinois researchers mine the crop's vast genomic potential in an effort to speed up the breeding process and maximize its most desirable traits.

It wasn't just hate. Fascism offered robust social welfare - Sheri Berman | Aeon Ideas - 0 views

  • There can be no question that violence and racism were essential traits of fascism. But for most Italians, Germans and other European fascists, the appeal was based not on racism, much less ethnic cleansing, but on the fascists’ ability to respond effectively to crises of capitalism when other political actors were not. Fascists insisted that states could and should control capitalism, that the state should and could promote social welfare, and that national communities needed to be cultivated. The fascist solution ultimately was, of course, worse than the problem. In response to the horror of fascism, in part, New Deal Democrats in the United States, and social democratic parties in Europe, also moved to re-negotiate the social contract. They promised citizens that they would control capitalism and provide social welfare policies and undertake other measures to strengthen national solidarity – but without the loss of freedom and democracy that fascism entailed.
  • The lesson for the present is clear: you can’t beat something with nothing. If other political actors don’t come up with more compelling solutions to the problems of capitalism, the popular appeal of the resurgent Right-wing will continue. And then the analogy with fascism and democratic collapse of the interwar years might prove even more relevant than it is now.

It wasn't just hate. Fascism offered robust social welfare | Aeon Ideas - 0 views

  • The origins of fascism lay in a promise to protect people. In the late 19th and early 20th centuries, a rush of globalisation destroyed communities, professions and cultural norms while generating a wave of immigration. Right-wing nationalist movements promising to protect people from the pernicious influence of foreigners and markets arose, and frightened, disoriented and displaced people responded. These early fascist movements disrupted political life in some countries, but they percolated along at a relatively low simmer until the Second World War.
  • After coming to power, the Italian fascists created recreational circles, student and youth groups, sports and excursion activities. These organisations all furthered the fascists’ goals of fostering a truly national community. The desire to strengthen (a fascist) national identity also compelled the regime to extraordinary cultural measures. They promoted striking public architecture, art exhibitions, and film and radio productions. The regime intervened extensively in the economy. As one fascist put it: ‘There cannot be any single economic interests which are above the general economic interests of the state, no individual, economic initiatives which do not fall under the supervision and regulation of the state, no relationships of the various classes of the nation which are not the concern of the state.’
  • When, in January 1933, Hitler became chancellor, the Nazis quickly began work-creation and infrastructure programmes. They exhorted business to take on workers, and doled out credit. Germany’s economy rebounded and unemployment figures improved dramatically: German unemployment fell from almost 6 million in early 1933 to 2.4 million by the end of 1934; by 1938, Germany essentially enjoyed full employment. By the end of the 1930s, the government was controlling decisions about economic production, investment, wages and prices. Public spending was growing spectacularly.
