Wild mammals as economic goods and implications for their conservation

Abstract

ABSTRACT. In social-ecological systems, human activities and animal distribution are interrelated. Any effort at studying wildlife abundance therefore requires the integration of detailed socioeconomic context into species distribution models. Wild mammals have always been an important resource for humankind, and concepts of economic goods provide an analytical framework to deduce relevant socioeconomic factors that shape wild mammal-human relationships and consequences for the spatial distribution patterns of wild mammals. We estimated the effects of the human population on wild mammals in a rural area in the Republic of Guinea, West Africa. We related large mammal survey data via statistical models to detailed socioeconomic information about the human population in the same area. We compared models, taking account of the human population in different ways, and found that wild mammal abundance was better explained by human factors other than human population density. Although human population density had a negative effect on wild mammals, the effect of market integration and food taboos were more important and not accounted for by human population density alone. Additionally, the analysis did not provide evidence of higher mammal abundance in classified forests, which one would assume if conservation interventions aimed at reducing hunting were implemented. Beyond doubt, the relationship between humans and wild mammals is highly complex and species-and context-specific. To understand mammal-human relationships in the wider context of social-ecological systems, an in-depth knowledge of the socioeconomic characteristics of a human population is needed to identify crucial links and driving mechanisms.

Novelty Response of Wild African Apes to Camera Traps

“…Comparable results report reduced neophobia in spotted hyenas living in areas with high human disturbance [38]. Furthermore, apes may be protected by local ''taboos'' [39] where they are not specifically targeted by hunters, permitting increased familiarity to novelty without a direct threat. Overall, our results confirm findings from captive studies on great apes but also highlight the impact of natural socio-ecological settings on reactions to novelty.…”

Advancing conservation planning for western chimpanzees using IUCN SSC A.P.E.S.—the case of a taxon-specific database

“…Chimpanzees in the Fouta Djallon and adjacent areas appear to be a large population characterized by savanna-mosaic habitat. Despite challenging ecological conditions (Wessling et al 2018), chimpanzees persist here at high densities due to relatively low levels of anthropogenic threats and a high prevalence of hunting taboos (Boesch et al 2017, Heinicke et al 2019. Chimpanzees in the second largest population live in a habitat mostly characterized by rainforest.…”

A preliminary survey of medium and large‐sized mammals from Lebu Natural Protected Forest, Southwest Showa, Ethiopia

“…They are also vital constituents of ecosystems (Boddicker, Rodriguez, & Amanzo, ), keeping ecological stability (Herrerias‐Diego et al, ). They are considered as an important resource for humankind and provide benefits such as a source of food and income generation like tusks, horns, and ivory (Boesch, Mundry, Kühl, & Berger, ).…”
