Zusammenfassung:
Camera traps (CTs) are used for wildlife monitoring globally. How CTs are used in wildlife studies across Africa, however, remains unknown. We provide the first literature review of CT studies conducted across Africa, to describe where, to what end, and by whom CTs are used, and to identify apparent gaps in the use of CTs. We found 172 CT studies published across 60 scientific journals, conducted in 30 of 55 African countries from 2005 to 2017. Most studies were conducted over a single year/season (74%) and primarily addressed habitat use/species distribution (43%), species presence/richness (38.4%), behaviour (35.5%) or demographics (29.7%). Most studies took place in forest (52%), woodland (33%) and grassland (33%) habitat types, and focused on a single species (45.3%). Carnivores were the most commonly studied species group (86%), followed by large herbivores (58%) and primates (38%). Our results suggest that camera trapping is rapidly increasing in use across Africa and potentially driven by country-based economic factors; however, there is room for improvement. CTs could be expanded in use for studies on underrepresented taxa (i.e. small mammals, reptiles and birds), investigations of human-wildlife conflict and understudied ecoregions (i.e. Sahara Desert).
