Here, Santer discusses how his research helps shift discussions of climate change from ideology to science. To uncover how climate affects the functional diversity of forests, Daniel Wieczynski et al. (pp. 587–592) analyzed data from 421 tree communities around the world, 66 of which were sampled in situ. Membership of the National Academy of Sciences is an award granted to scientists that the National Academy of Sciences (NAS) of the United States judges to have made “distinguished and continuing achievements in original research… Spor o globální oteplování se týká vědecké, politické a veřejné diskuse o tom, zda globální oteplování existuje, jak je v moderní době velké, co ho způsobuje, jaké důsledky bude mít, zda je třeba a zdali je naléhavé podniknout jakékoli… viruses were seen budding from many of the TEPI cells. the arrays from two to five.

The net effect was calculated as the sum of the standardized regression coefficients of all biodiversity attributes selected during the model selection procedures. How Earth’s history influenced the evolution of passerine diversity remains poorly understood. Carl Oliveros et al. (pp. 7916–7925) constructed a comprehensive passerine evolutionary tree based on DNA sequence data from representatives of… Empirical and theoretical work to understand how coexistence emerges from these dynamic interactions will be critical in the continuing quest to understand how so many tree species can coexist. To explore how self-assessments of life worth affect health and behavior, Andrew Steptoe and Daisy Fancourt (pp. 1207–1212) analyzed data from the English Longitudinal Study of Ageing, in which surveys were conducted among and biomarker… Sometimes entries in the table, which are next to each other, do not match perfectly. For example, Haeckel placed the red algae (Haeckel's Florideae; modern Rhodophyta) and blue-green algae (Haeckel's Archephyta; modern Cyanobacteria) in his… in relation to the revenue index: The lowest trophic level as- semblage has average annual revenues 39% higher than the top The findings could influence recently proposed, environmentally friendly alternatives to hydraulic fracturing that would free methane from shale beds using borehole-associated shock waves, thus minimizing the discharge of chemically…

To determine whether malaria transmission in Brazil is influenced by deforestation in the Amazon, Andrew MacDonald and Erin Mordecai (pp. 22212–22218) compared a dataset of malaria cases reported in 795 municipalities of the Brazilian… The National Academies Press (NAP) publishes authoritative reports issued by The National Academies of Science, Engineering, and Medicine (Nasem). aInstitute of Botany, Academy of Sciences of the Czech Republic, CZ-252 43 Průhonice, Czech Republic; bDepartment of Ecology, Faculty of Science, Charles University, CZ-128 01 Prague 2, Czech Republic; cBio-Protection Research Centre… The default mode network, shown here in resting-state fMRI scans (Upper), includes the posterior cingulate cortex, hippocampus, and the medial prefrontal cortex.

Participants heard the entrepreneur’s voice-over narration while they watched each video. The size difference may reduce the ability of lice from different hosts to mate and reproduce. In support of this idea, pairs of lice with typical sexual dimorphism in body size spent more time copulating, were more likely to produce eggs…
