ABSTRACT The multibillion-dollar trade in bushmeat is among the most immediate threats to the persistence of tropical vertebrates, but our understanding of its underlying drivers and effects on human welfare is limited by a lack of empirical data. We used 30 years of data from Ghana to link mammal declines to the bushmeat trade and to spatial and temporal changes in the availability of fish. We show that years of poor fish supply coincided with increased hunting in nature reserves and sharp declines in biomass of 41 wildlife species. Local market data provide evidence of a direct link between fish supply and subsequent bushmeat demand in villages and show bushmeat's role as a dietary staple in the region. Our results emphasize the urgent need to develop cheap protein alternatives to bushmeat and to improve fisheries management by foreign and domestic fleets to avert extinctions of tropical wildlife.

    ABSTRACT: Economic and social transition periods can have strong negative effects for the environment and for wildlife. The collapse of the Soviet Union in 1991 provides a striking example of social turmoil and transition to a new society. It is unclear, however, how humans affected the environment in the course of the collapse , and if institutions designed to safeguard the environment continued to fulfill their intended role. Our goal was to assess the impact of the collapse of the Soviet Union on forest canopy removal rates in protected areas, and how these rates varied by protected area status and over time. We monitored forest canopy removal within and outside of protected areas using a 1985–2010 time series of Landsat satellite images from the Western Caucasus. On average, we found surprisingly low annual forest canopy removal rates of only 0.03%. The highest canopy removal inside of protected areas of all types occurred after 2000. Among the protected areas, we found the highest canopy removal rates within Sochi National Park, attributable to construction for the Olympic Games and in spite of the Park's protected status. Overall, it is encouraging that forest canopy removal rates in protected areas in the Western Caucasus are far lower than in other Russian regions. Because many local endemic plant and animal species are found in the Caucasus region, clear cuts are prohibited, and this regulation appears to be effective. However, forest canopy removal within protected areas caused by major social and political events such as the Olympic Games is of concern.

    ABSTRACT: The Importance of bushmeat trade in Amazonian towns has been very little studied, either because it is thought to be insignificant or due to the context of illegality. Based on preliminary field work to identify the main stakeholders involved and the existing trade routes, our study aimed at describing the invisible bushmeat trade using a participatory monitoring protocol in Leticia and Puerto Nariño in Colombia, Tabatinga, Benjamin Constant and Atalaia do Norte in Brazil, and Santa Rosa and Caballococha in Peru. The monitoring system included two key levels of the market chain: hunters and market traders. With the support of our research team, the hunters and traders self monitored their activities during 60 days and 20 days respectively during two hydro-climatic periods. Our study shows that the most hunted species are paca, tericaya turtle and currassows while the most commercialized species are paca, tapir, collared peccary and the red brocket deer. We registered a total of 13 tons of bushmeat captured by hunters (from 29 species) and 6.7 tons of bushmeat sold by market sellers (from 19 species). We extrapolated this data to a year and to the total numbers of stakeholders involved in the trade and found that 473 tons of bushmeat are traded per year in market places from the main Tri frontier towns, which taken to the total urban population size of the area, equals to 3.2 kg/hab/year, a number that is comparable to those found in Central African urban settings.

    ABSTRACT: Native Papuans are relied on hunting for subsistence purposes and significantly contributed to traditional cultures. However, in Papua information on hunting is limited and largely restricted to anthropological setting with most observations were done on the forest sites in lowland and highland landscapes. This study focuses on the contribution of hunting on food security along the coastal forests at the Bird's Head Peninsula. Do people live near coastal sites mostly rely on marine resources as protein source? We gathered data on hunting by the majority of Karon ethnic group in the Abun district of Tambrauw Regency at the Bird's Head Peninsula of Papua, Indonesia. We used information from in-depth interviews with hunters and households meal survey at four villages of Abun: Waibem, Wau, Warmandi and Saubeba. Reasons for hunting were varies among respondents but mostly conducted for trade. Six species of mammals and three birds were commonly hunted by using six different hunting techniques. Wild pig and rusa deer were the major targets in hunting to meet the demand of meat for both trading and household consumption. Meals containing wildmeat was the most consumed meal, greater than meals containing fish, animal products and vegetables, and noodles.
