Summary Reliable estimates of animal density and abundance are essential for effective wildlife conservation management. Camera trapping has proven efficient sampling multiple species, but statistical estimators from camera data species that cannot be individually identified still in development. We extend point‐transect methods estimating to accommodate traps, allowing researchers exploit existing distance theory software designing studies analysing data. tested it by simulation, used...
The extension of distance sampling methods to accommodate observations from camera traps has recently enhanced the potential remotely monitor multiple species without need additional data collection (sign production and decay rates) or individual identification. However, method requires that proportion time is quantifiable when animals can be detected by cameras. This problematic, for instance, spend above ground, which case most primates. In this study, we aimed validate trap (CTDS)...
Empirical validations of survey methods for estimating animal densities are rare, despite the fact that only an application to a population known density can demonstrate their reliability under field conditions and constraints. Here, we present validation camera trapping in combination with spatially explicit capture-recapture (SECR) enumerating chimpanzee populations. We used 83 traps sample habituated community western chimpanzees (Pan troglodytes verus) territory size Taï National Park,...
Abstract As camera trapping grows in popularity and application, some analytical limitations persist including processing time accuracy of data annotation. Typically images are recorded by traps although videos becoming increasingly collected even though they require much more for To overcome with image annotation, trap studies linked to community science (CS) platforms. Here, we extend previous work on CS annotations from a challenging environment; dense tropical forest low visibility high...
Abstract Distance sampling ( DS ) is a widely used framework for estimating animal abundance. models assume that observations of distances to animals are independent. Non‐independent introduce overdispersion, causing model selection criteria such as AIC or c favour overly complex models, with adverse effects on accuracy and precision. We describe, evaluate via simulation real data, estimators an overdispersion factor ), associated adjusted QAIC use overdispersed data. In other contexts,...
Demographic factors can strongly influence patterns of behavioral variation in animal societies. Traditionally, these are measured using longitudinal observation habituated social groups, particularly animals like primates. Alternatively, noninvasive biomonitoring methods such as camera trapping allow researchers to assess species occupancy, estimate population abundance, and study rare behaviors. However, measures fine‐scale demographic variation, those related age sex structure or...
Abstract Citizen science has grown rapidly in popularity recent years due to its potential educate and engage the public while providing a means address myriad of scientific questions. However, rise citizen also been accompanied by concerns about quality data emerging from research projects. We assessed online scientist platform Chimp&See, which hosts camera trap videos chimpanzees ( Pan troglodytes ) other species across Equatorial Africa. In particular, we compared detection...
Carrion scavenging is a well‐studied phenomenon, but virtually nothing known about on plant material, especially remnants of cracked nuts. Just like meat, the insides hard‐shelled nuts are high in energetic value, and both foods difficult to acquire. In Taï forest, chimpanzees ( Pan troglodytes ) red river hogs Potamochoerus porcus crack by using tools or strong jaws, respectively. this study, previously collected non‐invasive camera trap data were used investigate sooty mangabeys Cercocebus...
