Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark pine populations require an understanding of all aspects of seed fate. In this paper, we review the literature on seed dispersal in whitebark pine. Clark's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and ultimately affect the ability of whitebark pine populations to regenerate. We also provide a general overview of the natural histories of the most influential species involved with whitebark pine seed fate: Clark's nutcracker and the pine squirrel.

Nontimber forest products (NTFPs) are fundamental to the functioning of healthy forests and play vital roles in the cultures and economies of the people of the United States. However, these plants and fungi used for food, medicine, and other purposes have not been fully incorporated into management, policy, and resource valuation. This report is a forest-sectorwide assessment of the state of the knowledge regarding NTFPs science and management information for U.S. forests and rangelands (and hereafter referred to as the NTFP assessment). The NTFP assessment serves as a baseline science synthesis and provides information for managing nontimber forest resources in the United States. In addition, this NTFP assessment provides information for national-level reporting on natural capital and the ecosystem services NTFPs provide. The report also provides technical input to the 2017 National Climate Assessment (NCA) under development by the U.S. Global Change Research Program (USGCRP).

Ecosystems are the stage on which the play of evolution is acted, and ecosystems are complex, spatially structured and temporally varying. The purpose of this Research Topic is to explore critical challenges and opportunities for the transition from landscape genetics to landscape genomics. Landscape genetics has focused on the spatial analysis of small genetic datasets, typically comprised of less than 20 microsatellite markers, taken from clusters of individuals in putative populations or distributed individuals across landscapes. The recent emergence of large scale genomic datasets produced by next generation sequencing methods poses tremendous challenge and opportunity to the field. Perhaps the greatest is to produce, process, curate, archive and analyze spatially referenced genomic datasets in a way such that research is led by a priori hypotheses regarding how environmental heterogeneity and temporal dynamics interact to affect gene flow and selection. The papers in the Research Topic cover a broad range of topics under this area of focus, from reviews of the emergence of landscape genetics, to best practices in spatial analysis of genetic data. The compilation, like the emerging field itself, is eclectic and illustrates the scope of both the challenges and opportunities of this emerging field.

The 7-volume Encyclopedia of Biodiversity, Second Edition maintains the reputation of the highly regarded original, presenting the most current information available in this globally crucial area of research and study. It brings together the dimensions of biodiversity and examines both the services it provides and the measures to protect it. Major themes of the work include the evolution of biodiversity, systems for classifying and defining biodiversity, ecological patterns and theories of biodiversity, and an assessment of contemporary patterns and trends in biodiversity. The science of biodiversity has become the science of our future. It is an interdisciplinary field spanning areas of both physical and life sciences. Our awareness of the loss of biodiversity has brought a long overdue appreciation of the magnitude of this loss and a determination to develop the tools to protect our future. Second edition includes over 100 new articles and 226 updated articles covering this multidisciplinary field— from evolution to habits to economics, in 7 volumes The editors of this edition are all well respected, instantly recognizable academics operating at the top of their respective fields in biodiversity research; readers can be assured that they are reading material that has been meticulously checked and reviewed by experts Approximately 1,800 figures and 350 tables complement the text, and more than 3,000 glossary entries explain key terms

Describes a prototype whitebark pine seed scarifier developed by the Missoula Technology and Development Center that allows workers to nick (scarify) seeds three times as fast as if they were doing so by hand, with reduced risk of injury. Populations of whitebark pine have declined over the past century because of white pine blister rust, insect infestations, and fire suppression. Whitebark pine seeds are a favored food of the grizzly bear, a threatened species protected by the Endangered Species Act in the 48 contiguous States. Whitebark pine trees, which may be the only trees growing in some sub-alpine and alpine areas of the northern Rocky Mountains, also catch snow during the winter. The drifts melt more slowly than thinner snowpack in bare areas, extending runoff. The scarifier should help reduce the costs of growing whitebark pine seedlings, possibly allowing more whitebark pines to be planted. Seeds collected from white-bark pine trees resistant to blister rust are germinated in nurseries. The germination rate increases from about 5 percent to 60 percent or more if each seed has a 1-mm-deep nick. Workers can nick about 400 seeds an hour by hand, compared to 1,500 seeds an hour when using the prototype scarifier. The scarifier costs about $1,000 to fabricate. Fabrication drawings will be available from the Missoula Technology and Development Center.
