... The Natural & Physical Science (NPS) Libraries of the Smithsonian Libraries consist of several locations serving the National Museum of Natural History, the Smithsonian Environmental Research Center, the Smithsonian’s National Zoological Park and Conservation Biology Institute, and the Smithsonian Tropical Research Institute in Panama. Much has been written about the dramatic shift in recent years to the changing face of university research environments, but there are few recent studies on the use of libraries by museum and research center staff. Together and with the members of the NPS Libraries Advisory Committee consisting of staff scientists and other departments, we developed surveys and other feedback mechanisms that investigated museum and research center staff’s research and scholarly publishing practices. Questions included use of library print and digital collections for research, service and training priorities, methods employed to find scholarly journal articles, Open Access publishing funding and practices, and data management. The poster will provide the results of this and other research and our libraries’ strategies in response to the findings.

... Liverworts and mosses are a major component of the epiphyte flora of tropical montane forest ecosystems. Canopy access was used to analyse the distribution and vertical stratification of bryophyte epiphytes within tree crowns at nine forest sites across a 3400 m elevational gradient in Peru, from the Amazonian basin to the high Andes. The stable isotope compositions of bryophyte organic material (13C/12C and 18O/16O) are associated with surface water diffusive limitations and, along with C/N content, provide a generic index for the extent of cloud immersion. From lowland to cloud forest Î´13C increased from -33â ° to -27â °, while Î´18O increased from 16.3â ° to 18.0â °. Epiphytic bryophyte and associated canopy soil biomass in the cloud immersion zone was estimated at up to 45 t dry mass ha-1, and overall water holding capacity was equivalent to a 20 mm precipitation event. The study emphasizes the importance of diverse bryophyte communities in sequestering carbon in threatened habitats, with stable isotope analysis allowing future elevational shifts in the cloud base associated with changes in climate to be tracked.

... Data on paired seed traps from Barro Colorado Island in Panama. 200 paired traps were installed 2 m distance in March 2011 and censused weekly through February 2013 along the trails of the 50ha plot. Each trap consisted of a square ½ m2, open-topped, 1-mm mesh bag supported 0.8 to 1 m above the ground by a polyvinyl chloride frame. Fruits and seeds were identified to species, counted and further categorized as immature, mature (endosperm filled), or damaged by animals. PART definitions: 0 reproductive buds, 1 mature fruit, 2 seeds, 3 capsules, 4 fragments, 5 immature fruit, 6 flowers (female or perfect), 7 fruit with insect emergence holes / insect damaged, 8 aborted fruit, 9 male flowers, 10 fruit eaten by animal (bird, monkey, squirrel o others), 11 category for leaves, 12 "unknown", 13 leaf pedicel, 14 fragment og branch, less than 2 cm in diameter, 15 fine litter, 16 flower pedicel, 17 fruit pedicel, 18 monkey feces.
