Understanding continent-wide variation in vulture ranging behavior to assess feasibility of Vulture Safe Zones in Africa: Challenges and possibilities

Protected areas are intended as tools in reducing threats to wildlife and preserving habitat for their long-term population persistence. Studies on ranging behavior provide insight into the utility of protected areas. Vultures are one of the fastest declining groups of birds globally and are popular subjects for telemetry studies, but continent-wide studies are lacking. To address how vultures use space and identify the areas and location of possible vulture safe zones, we assess home range size and their overlap with protected areas by species, age, breeding status, season, and region using a large continent-wide telemetry datasets that includes 163 individuals of three species of threatened Gyps vulture. Immature vultures of all three species had larger home ranges and used a greater area outside of protected areas than breeding and non-breeding adults. Cape vultures had the smallest home range sizes and the lowest level of overlap with protected areas. Rüppell\u27s vultures had larger home range sizes in the wet season, when poisoning may increase due to human-carnivore conflict. Overall, our study suggests challenges for the creation of Vulture Safe Zones to protect African vultures. At a minimum, areas of 24,000 km2 would be needed to protect the entire range of an adult African White-backed vulture and areas of more than 75,000 km2 for wider-ranging Rüppell\u27s vultures. Vulture Safe Zones in Africa would generally need to be larger than existing protected areas, which would require widespread conservation activities outside of protected areas to be successful

Binary and Millisecond Pulsars at the New Millennium

We review the properties and applications of binary and millisecond pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1300. There are now 56 binary and millisecond pulsars in the Galactic disk and a further 47 in globular clusters. This review is concerned primarily with the results and spin-offs from these surveys which are of particular interest to the relativity community.Comment: 59 pages, 26 figures, 5 tables.

Binary and Millisecond Pulsars

We review the main properties, demographics and applications of binary and millisecond radio pulsars. Our knowledge of these exciting objects has greatly increased in recent years, mainly due to successful surveys which have brought the known pulsar population to over 1700. There are now 80 binary and millisecond pulsars associated with the disk of our Galaxy, and a further 103 pulsars in 24 of the Galactic globular clusters. Recent highlights have been the discovery of the first ever double pulsar system and a recent flurry of discoveries in globular clusters, in particular Terzan 5.Comment: 77 pages, 30 figures, available on-line at http://www.livingreviews.org/lrr-2005-

The British Columbia Farmers' Market Nutrition Coupon Program reduces short-term household food insecurity among adults with low incomes: a pragmatic randomized controlled trial.

The British Columbia Farmers' Market Nutrition Coupon Program (BC FMNCP) provides households with low incomes with coupons to purchase healthy foods from farmers' markets.To examine the impact of the BC FMNCP on the short-term household food insecurity, malnutrition risk, mental well-being, sense of community (secondary outcomes), and subjective social status (exploratory outcome) of adults with low incomes post-intervention and 16 weeks post-intervention.Secondary analyses from a pragmatic randomized controlled trial conducted in 2019 that collected data at baseline, post-intervention, and 16 weeks post-intervention.Adults ≥18 years with low incomes were randomized to a FMNCP group (n=143) or a no-intervention control group (n=142).Participants in the FMNCP group received 16 coupon sheets valued at $21 Canadian dollars (CAD)/sheet over 10-15 weeks to purchase healthy foods from farmers' markets and were eligible to participate in nutrition skill-building activities.Outcomes included short-term household food insecurity (modified version of Health Canada's 18-item Household Food Security Survey Module), malnutrition risk (Malnutrition Universal Screening Tool), mental well-being (Warwick-Edinburgh Mental Well-Being Scale), sense of community (Brief Sense of Community Scale), and subjective social status (MacArthur Scale of Subjective Social Status community scale)
