<jats:title>Global biodiversity and productivity</jats:title><jats:p>The relationship between biodiversity and ecosystem productivity has been explored in detail in herbaceous vegetation, but patterns in forests are far less well understood. Liang<jats:italic>et al.</jats:italic>have amassed a global forest data set from &gt;770,000 sample plots in 44 countries. A positive and consistent relationship can be discerned between tree diversity and ecosystem productivity at landscape, country, and ecoregion scales. On average, a 10% loss in biodiversity leads to a 3% loss in productivity. This means that the economic value of maintaining biodiversity for the sake of global forest productivity is more than fivefold greater than global conservation costs.</jats:p><jats:p><jats:italic>Science</jats:italic>, this issue p.<jats:related-article issue="6309" page="196" related-article-type="in-this-issue" vol="354">196</jats:related-article></jats:p>

<jats:p> Earlier this year, a number of leaders from major U.S. corporations gathered at Sunnylands in California to discuss the critical importance of basic scientific research. For decades, the private sector has withdrawn from some areas of basic research, as accelerating market pressures, the speed of innovation, and the need to protect intellectual property in a global marketplace made a Bell Labs–style, in-house model of discovery and development hard to sustain. However, the leaders who gathered for the “CEOs and Leaders for Science” retreat <jats:xref ref-type="fn">*</jats:xref> (which we convened) agreed that basic research will make or break corporations in the long term. Why? </jats:p>
