We detected Heartland virus (HRTV) in lone star nymphs collected in 2018 in northern Alabama, USA. Real-time reverse transcription PCR selective for the small segment of the HRTV genome and confirmatory sequencing of positive samples showed high identity with HRTV strains sequenced from Tennessee…

Spatially explicit data on the location of species across broad geographic areas greatly facilitate effective conservation planning on lands managed for multiple uses. The importance of these data notwithstanding, our knowledge about the geography of biodiversity is remarkably incomplete. An…

In Puerto Rico, an island in the West Indies, large areas of primary forest have been cut and converted to farmland or to secondary forest; subsequently the farmlands declined in fertility and were abandoned. Various tree species were planted in order to restore the degraded land and to provide…

Oregon’s Land Use Planning Program is often cited as an exemplary approach to protecting forest and farm lands from development. In November 2004, Oregon voters approved a ballot measure—Measure 37—to require the state to compensate landowners for any property value losses resulting from land use…

There is little question that global warming would increase the risk of wildfires by drying out vegetation and stirring the winds that spread fire. Until recently, however, land managers were unable to formulate appropriate responses because the spatial scales of predictions were far too coarse.…
