The Efficiency of Motorcycle Use in Illegal Bushmeat Transportation in
Western Serengeti, Tanzania
- Abstract: Bushmeat is an important source of protein, as well as economic income for communities in sub-Saharan Africa and Latin America. This study was conducted in north-western Serengeti, Tanzania, from July to September of 2019. Two villages were sampled for distance calculation: Kowak and Robanda. The snowballing technique was the sampling design adopted. Trained assistants identified at least one bushmeat vendor in each village to be interviewed, who was thereafter asked to identify another vendor known to him/her. The number of days spent delivering bushmeat packages to the illegal market (an average of 200 km) from the bushmeat source was 16.8 days when using donkeys, 6.8 days when using bicycles, and 2.0 days when using motorcycles. Motorcycles were 8.4 and 3.4 times more efficient than donkeys and bicycles, respectively. Bicycles were 2.5 times more efficient than donkeys. The mean weights of bushmeat packages delivered by donkeys were 188.4 kg and 109.0 kg when using bicycles. Motorcycles delivered 185.0 kg of bushmeat per trip. The mean weights carried by donkeys and motorcycles were 1.7 times higher than those of bicycles. The mean depletion rates of motorcycles were 92.5 kg of bushmeat per day for a distance of 200 km. Bicycles depleted 16.0 kg, while donkeys only depleted 11.2 kg per day to the market. The use of motorcycles in bushmeat transportation increased the efficiency in delivering illegal bushmeat to predetermined illegal markets, and thus resulted in a high depletion rate. Wildlife authorities should introduce patrol systems that include the control of motorcycles close to protected areas. There should be day and night checkpoints in various places, such as large bridges that cannot be avoided and along rural pathways.

Differing Fine-Scale Responses of Vegetation and Bare Soil to Moisture
Variation in a Pinyon-Juniper Woodland Underlie Landscape-Scale Responses
Observed from Remote Sensing
- Abstract: Pinyon juniper woodlands in the American southwest face an uncertain ecological future with regard to climate altered precipitation. Although satellite remote sensing will be relied upon to assess the overall health of these plant communities more fine scaled information is needed to elucidate the mechanisms shaping the broader scaled regional assessments. We conducted a study to assess the NDVI response at the plant canopy level (insitu sensors placed over the canopies) of three tree and one shrub species to changes in precipitation, reference evapotranspiration and soil volumetric water content. Landsat data was used to compare stand integrated and satellite NDVI values. We also provided supplemental water in the amount of 10.85 cm over the study period to additional trees and shrubs which also had insitu NDVI sensors placed over their canopies. NDVI at the canopy level separated statistically by species and when contrasted with bare soil (p
