“…On the other hand, in addition to humans, bamboo shoots are beneficial and tasty food for animals. Bamboo shoots are a source food for some rare animals such as African golden monkeys ( Cercopithecus mitis kandti ), mountain gorillas ( Gorilla beringei beringei ) [ 120 ], and especially panda, which guarantees the survival of the panda generation [ 121 ]. In general, bamboo, as a beneficial plant with plenty of fiber, plays a considerable role in the food chain of humans and especially in animals.…”

Bamboo forests are undoubtedly one of the most abundant nontimber plants on Earth and cover a wide area of tropical and subtropical regions around the world. This amazing plant has unique rapid growth and can play an important role in protecting our planet from pollution and improving the soil. Bamboo can be used as a biofuel, food, and for architecture and construction applications and plays a large role in the local economy by creating job opportunities. The aim of this paper is to review the extraordinary tropical plant bamboo by explaining the mechanisms related to the growth and strength of bamboo and identifying ways to utilize bamboo in industry, employment, climate change mitigation, and soil erosion reduction.

Analysis of Climate and Topography Impacts on the Spatial Distribution of Vegetation in the Virunga Volcanoes Massif of East-Central Africa

et al. 2017

This paper aimed to investigate the influence of climatic and topographic factors on the distribution of vegetation in the Virunga Volcanoes Massif using GIS and remote sensing techniques. The climatic variables considered were precipitation, Land Surface Temperature (LST), and evapotranspiration (ET), whereas the topographic factors considered were elevation and aspect. The dataset consisted of MODIS NDVI data, satellite-delivered precipitation, ET, and the LST. A 2014 Landsat 8 OLI image was used to produce a vegetation map of the study area, while DEM was used to derive the elevation attributes and to calculate the aspect angles. Moran's I and Geographically Weighted Regression (GWR) Model was used to analyze the relationships between the climatic factors and NDVI changes over elevation and aspect. The results indicated that among the nine vegetation types inventoried in the area, the Mean NDVI varied from 0.33 to 0.59 and the optimal vegetation growth was found at an elevation between 2000 and 3900 m, with mean NDVI values larger than 0.50. The peak mean NDVI value of 0.59 was found at the elevation from 2100 to 2800 m. Vegetation growth was found to be more sensitive to elevation, as NDVI values were more varied at a lower elevation (<4000 m) than at a higher elevation (>4000 m). Considering the aspect, the greater vegetation growth was found in SE (132 • , 148 • ), SW (182 • , 186 • ), and NW (309.5 • -337.5 • ), with mean NDVI values larger than 0.56. This indicated that vegetation was susceptible to better growth conditions in the lower elevation ranges and in shady areas. The vegetation NDVI in this study area was mostly uncorrelated with precipitation (R 2 = 0.34), but was strongly correlated with LST (R 2 = 0.99) and ET (R 2 = 98). LST (≥18 • C) and ET (1286 mm/year −1 ) were found to provide optimal conditions for vegetation growth in the Virunga Volcanoes Massif. Empirically, the results concluded that elevation, aspect, LST, and ET are the main factors controlling the spatial distribution and vegetation growth in this area. This information is significantly helpful for biodiversity conservation and constitutes a valuable input to environmental and ecological research.

“…If certain wild plant resources are exploited heavily or destructively by people and wildlife, and these resources show low temporal or spatial availability, this might lead to their decline over time. However, if access to plant resources is restricted, for example through government regulations preventing the harvest of rare plant species, this can create hostility between local user groups, and between local people and authorities, which equally might compromise wildlife conservation objectives (Sheil et al, 2012;Redpath et al, 2013). Furthermore, if animals exploit resources which people value it can lead to their retaliatory persecution (Hockings and Humle, 2009).…”

“…Secondly, data on plant selection by humans and primates are often collected over different time periods and geographical areas, making it difficult to assess the extent of shared resource use across space and time, and potential ecological drivers (e.g., plant availability) (Chepstow-Lusty et al, 2006;Riley, 2007). Thirdly, investigation can focus on a single plant species that is confirmed as important to humans and primates (Kinnaird, 1992;Reynolds et al, 2012;Sheil et al, 2012;Waller and Pruetz, 2016). Although this approach can yield important information on spatial and temporal overlap in the use of a single resource that is heavily exploited by both, it provides an incomplete picture where humans and primates select numerous plants and plant parts across different seasons.…”

Extensive Overlap in the Selection of Wild Fruits by Chimpanzees and Humans: Implications for the Management of Complex Social-Ecological Systems

Understanding the capacity for humans to share resources (crops, wild foods, space) with large-bodied wildlife is vital for biodiversity conservation and human wellbeing, and requires comprehensive examination of their temporal interactions over fine spatial scales. We combined ecological (plant identification, wild fruit availability plots, animal fecal and trace sampling) and social science (free-listing, semi-structured interviews, participant observation) methods to systematically and simultaneously collect data on the availability and selection of fruits from wild plants by humans and critically endangered chimpanzees (Pan troglodytes verus), a national conservation flagship species at Cantanhez National Park, Guinea-Bissau. Within an area of 12.7 km 2 , we demonstrate that local people's monthly use of wild fruits was driven by its overall availability in the habitat, whereas chimpanzees, as ripe fruit specialists, sought out fruits year-round. Humans and chimpanzees overlap in the selection of fruits from at least 27 wild plant species. The ranked use of fruits from species which were used by both chimpanzees and humans was significantly positively correlated, suggesting they preferentially target fruits of the same wild plant species. Each month, humans and chimpanzees selected three to six of the same wild fruit species. Chimpanzees fed significantly more on wild fruit species that were available for longer periods, with no effect of that plant species density. Neither plant density nor number of fruiting months impacted human selection of fruit from a plant species, suggesting people might seek out desired resources irrespective of a species' abundance in the landscape. These findings are important for the development of a shared knowledge base to establish culturally relevant conservation management strategies. We recommend the active management of plant species that are exploited for their fruits by both humans and chimpanzees at Cantanhez National Park, including figs (Ficus spp.), oil-palm (Elaeis guineensis) and velvet tamarind (Dialium guineense). This can be achieved through supporting traditional resource management practices and the strategic replanting of
