Brutsaert, Tom D. ; Kiyamu, Melisa ; Elias Revollendo, Gianpietro ; Isherwood, Jenna L. ; Lee, Frank S. ; Rivera-Ch, Maria ; Leon-Velarde, Fabiola ; Ghosh, Sudipta ; Bigham, Abigail W. | National Academy of Sciences | 2019-12-06T21:02:54ZHighland native Andeans have resided at altitude for millennia. They display high aerobic capacity (VO2max) at altitude, which may be a reflection of genetic adaptation to hypoxia. Previous genomewide (GW) scans for natural selection have nomin[...]texto impreso
Tejada, J.V. ; Flynn, J.J. ; Antoine, P.-O. ; Pacheco, V. ; Salas-Gismondi, R. ; Cerling, T.E. | National Academy of Sciences | 2020-12-14T16:10:17ZClosed-canopy rainforests are important for climate (influencing atmospheric circulation, albedo, carbon storage, etc.) and ecology (harboring the highest biodiversity of continental regions). Of all rainforests, Amazonia is the world's most div[...]texto impreso
Defrance, Dimitri ; Ramstein, Gilles ; Charbit, Sylvie ; Vrac, Mathieu ; Moise Famien, Adjoua ; Sultan, Benjamin ; Swingedouw, Didier ; Dumas, Christophe ; Gemenne, François ; Álvarez Solas, Jorge ; Vanderlinden, Jean-Paul | National Academy of Sciences | 2017-06-20The acceleration of ice sheet melting has been observed over the last few decades. Recent observations and modeling studies have suggested that the ice sheet contribution to future sea level rise could have been underestimated in the latest Inte[...]texto impreso

Here we examined the evolutionary history of parasites of the Leishmania braziliensis species complex based on whole-genome sequencing of 67 isolates f[...]texto impreso
Caramanica, A. ; Mesia, L.H. ; Morales, C.R. ; Huckleberry, G. ; Luis Jaime Castillo, B. ; Quilter, J. | National Academy of Sciences | 2020-12-14T16:06:12ZEl Niño-Southern Oscillation has been treated as a disruptor of environmental and socioeconomic equilibrium both in ancient times and in modern-day Peru. Recent work in the coastal desert plain, known as the Pampa de Mocan, challenges this view [...]texto impreso
Griffiths, Scott ; Mesarich, Carl-H. ; Saccomanno, Benedetta ; Vaisberg, Abraham ; De-Wit, Pierre-J. G. M. ; Cox, Russell ; Collemare, Jerome | National Academy of Sciences | 2019-02-06T14:45:34ZAnthraquinones are a large family of secondary metabolites (SMs) that are extensively studied for their diverse biological activities. These activities are determined by functional group decorations and the formation of dimers from anthraquinone[...]texto impreso
Masanes, Lluís ; Muller, Markus P. ; Augusiak, Remigiusz ; Pérez García, David | National Academy of Sciences | 2013-10Does information play a significant role in the foundations of physics? Information is the abstraction that allows us to refer to the states of systems when we choose to ignore the systems themselves. This is only possible in very particular fra[...]texto impreso

The Neolithization of Europe has been associated with large-scale migrations from [...]texto impreso
van Dorp, Lucy ; Lowes, Sara ; Weigel, Jonathan L. ; Ansari-Pour, Naser ; López, Saioa ; Mendoza-Revilla, Javier ; Robinson, James A. ; Henrich, Joseph ; Thomas, Mark G. ; Nunn, Nathan ; Hellenthal, Garrett | National Academy of Sciences | 2019-07-04T16:59:36ZFew phenomena have had as profound or long-lasting consequences in human history as the emergence of large-scale centralized states in the place of smaller scale and more local societies. This study examines a fundamental, and yet unexplored, co[...]texto impreso
Álvarez Solas, Jorge ; Robinson, Alexander James ; Montoya Redondo, María Luisa ; Ritz, Catherine | National Academy of Sciences | 2013-10-08Proxy data reveal the existence of episodes of increased deposition of ice-rafted detritus in the North Atlantic Ocean during the last glacial period interpreted as massive iceberg discharges from the Laurentide Ice Sheet. Although these have lo[...]texto impreso
