The cover illustration portrays a landscape in which terrestrial and marine protected areas are connected through corridors of natural or restored habitat and surrounded by buffer and multiple-use zones to ensure the long-term conservation of biodiversity. In this vision, landscapes are managed for ecosystem services such as clean water, soil stability,(More)
and restore forest ecosystems by promoting incentives that diversify trade in the forest sector, moving beyond exclusive focus on lumber and fiber, to a broader range of products and services. To fulfill its mission Forest Trends works to accelerate development of markets for forest ecosystem services, expand markets of sustainably produced forest products(More)
Lagerstroemia (crape myrtle) is an important plant genus used in ornamental horticulture in temperate regions worldwide. As such, numerous hybrids have been developed. However, DNA sequence resources and genome information for Lagerstroemia are limited, hindering evolutionary inferences regarding interspecific relationships. We report the complete plastid(More)
Since 2006, beekeepers have reported increased losses of Apis mellifera colonies, and one factor that has been potentially implicated in these losses is the microsporidian Nosema ceranae. Since N. ceranae is a fairly recently discovered parasite, there is little knowledge of the variation in infection levels among individual workers within a colony. In this(More)
The Venus Science and Technology Definition Team (STDT) was formed by NASA to look at science objectives, mission architecture, science investigations, and instrument payload for a Flagship-class mission to Venus. This $3-4B mission, to launch in the 2020-2025 timeframe, should revolutionize our understanding of how climate works on terrestrial planets,(More)
Female mating frequency is one of the key parameters of social insect evolution. Several hypotheses have been suggested to explain multiple mating and considerable empirical research has led to conflicting results. Building on several earlier analyses, we present a simple general model that links the number of queen matings to variance in colony performance(More)
The calibration of measurement systems is a fundamental but under-studied problem within industrial statistics. The origins of this problem go back to basic chemical analysis based on NIST standards. In today's world these issues extend to mechanical, electrical, and materials engineering. Often, these new scenarios do not provide " gold standards " such as(More)
Introduction: The Venus Science and Technology Definition Team (STDT) was created by NASA's Science Mission Directorate to formulate the science goals and objectives, and to design the mission architecture , science investigations, and instrument payload for a Flagship-class mission to Venus. It was also tasked to develop a prioritized technology roadmap to(More)
