Premise The effective ex situ conservation of exceptional plants, whether in living collections or cryo‐collections, requires more resources than the conservation of other species. Because of their expertise with rare plants, botanical gardens are well positioned to lead this effort, but a well‐developed strategy requires a clear understanding of the resources needed. Methods Grant funding was obtained from the Institute of Museum and Library Services to support a three‐year project on cryobanking, and to provide smaller grants to 10 other botanical gardens for one‐year projects on either (1) seed behavior studies or (2) the development of protocols for in vitro propagation or cryopreservation. Results Nine of the partner gardens worked on 19 species (one was unable to continue due to the COVID‐19 pandemic), while the larger project focused on 14 species. A point system was developed for tasks accomplished, and the average costs per point of the larger and smaller projects were similar. Labor accounted for half the costs. Projects focused on species in the Asteraceae and Orchidaceae had lower costs per point than other species. Discussion Both large and small projects can contribute to a strategy for exceptional plant conservation for similar costs. Prioritizing species with lower costs could help advance the field while allowing time for work on more difficult species to develop.
Transparent magnetic glass-ceramics were produced by infiltrating nano-porous glass with nitrate salts and firing. The resultant glass-ceramics contained spinel ferrite nanocrystals that exhibited ferromagnetic and superparamagnetic behavior depending on composition and firing temperature. Transparency in the near infrared was obtained when oxidizing conditions were used to prevent Fe 21 formation, while the porous matrix ensured nano-sized crystallites to limit scattering losses. MnFe 2 O 4 glassceramics treated at 10001C offered the best combination of magnetic and optical properties with a saturation magnetization of 5.6 emu/g, a Verdet constant of 16.51/cm, and losses below 3 dB/mm at 1550 nm.
County health departments typically bear responsibility for implementing immunization programs. In 2011, the Florida state legislature made significant reductions in state health department funding, and responsibility for routine childhood immunizations in some counties was shifted to local federally qualified health centers. This study was conducted to assess the impact of these administrative changes on childhood immunization rates in one county. A secondary analysis of data in the state immunization registry was conducted to assess changes and patterns in childhood immunization rates within the local health department, federally qualified health centers, and private pediatric practices. These changes were compared in the 3-year period before, during, and after the change. Results revealed that there was no net negative change in the vaccination rates of 0- to 7-year-old children in the county. There was a shift in the proportion of vaccinations administered by each health care delivery setting. The majority of immunizations were administered in private pediatric practices. When state funding for the local public health department ceased, other delivery settings covered the immunizations previously provided in the public health sector.
