“…There are important differences among savanna chimpanzee research sites because of their specific biogeography and local history. There is some variability in plant and animal communities, although aridity and high temperatures shape the organisms that succeed in these stressful environments (Wessling et al 2020; reviewed in Domínguez-Rodrigo 2014). The degree of anthropogenic impact, consequent habitat disruption, and direct or indirect competition with humans vary across sites.…”

“…The Fongoli Savanna Chimpanzee Project achieved habituation in 2005. With that accomplishment has come a wealth of significant insights into the behavior, ecology, and physiology of this community of chimpanzees, including direct behavioral evidence of how chimpanzees cope with aridity and heat stress while managing to meet nutritional demands (Bogart and Pruetz 2011;Lindshield et al 2017;Pruetz and Bertolani 2009;Wessling et al 2018a; see also Boyer Ontl and Stewart and Pruetz, 2020;Wessling et al 2020).…”

“…One aspect of contextualizing savanna sites is by categorizing/classifying habitats. Three papers in this special issue (Pennec et al 2020, van Leeuwen et al 2020, and Wessling et al, 2020 seek to objectively quantify (habitat) components of savannamosaic landscapes for Pan species. While dense forest characterizes most landscapes with bonobos (e.g., Hickey et al 2012), Pennec et al 2020 characterize the habitat of a group of bonobos living in a mosaic of savanna and forest.…”

“…Wessling et al (2020) investigate components of the chimpanzee biogeographical range edge as a means of understanding the species' biogeographical limits. Building on the work of others in the region (Baldwin 1979;Bogart and Pruetz 2011;Lindshield et al 2019a), Wessling et al (2020) provide explicit description of habitat characteristics of Fongoli, Dindefelo, and four additional sites in Senegal, and relate these patterns to the structure of the range edge of the western chimpanzee. Chimpanzee densities declined in parallel to multiple floristic and abiotic metrics with proximity to the range limit, the characterization of which provides clear floristic differences (e.g., reduced floristic diversity and lower tree densities) from more central chimpanzee research sites.…”

“…Rather, the habitats they occupy, as implied by the use of "savanna," are more open; may include woodland, grassland; and are often labeled mosaic habitats (Hunt and McGrew 2002). These habitats also represent some of the extremes of where chimpanzees can persist-occupying the biogeographical edges of the species' distribution (Wessling et al 2020).…”

The new field of primate archaeology investigates the technological behavior and material record of nonhuman primates, providing valuable comparative data on our understanding of human technological evolution. Yet, paralleling hominin archaeology, the field is largely biased toward the analysis of lithic artifacts. While valuable comparative data have been gained through an examination of extant nonhuman primate tool use and its archaeological record, focusing on this one single aspect provides limited insights. It is therefore necessary to explore to what extent other non‐technological activities, such as non‐tool aided feeding, traveling, social behaviors or ritual displays, leave traces that could be detected in the archaeological record. Here we propose four new areas of investigation which we believe have been largely overlooked by primate archaeology and that are crucial to uncovering the full archaeological potential of the primate behavioral repertoire, including that of our own: (1) Plant technology; (2) Archaeology beyond technology; (3) Landscape archaeology; and (4) Primate cultural heritage. We discuss each theme in the context of the latest developments and challenges, as well as propose future directions. Developing a more “inclusive” primate archaeology will not only benefit the study of primate evolution in its own right but will aid conservation efforts by increasing our understanding of changes in primate‐environment interactions over time.

Characteristics of food availability and distribution are key components of a species' ecology. Objective ecological surveying used in animal behavior research does not consider aspects of selection by the consumer and therefore may produce imprecise measures of availability. We propose a method to integrate ecological sampling of an animal's environment into existing behavioral data collection systems by using the consumer as the surveyor. Here, we evaluate the consumer‐centric method (CCM) of assessing resource availability for its ability to measure food resource abundance, distribution, and dispersion. This method catalogs feeding locations observed during behavioral observation and uses aggregated data to characterize these ecological metrics. We evaluated the CCM relative to traditional vegetation plot surveying using accumulated feeding locations across 3 years visited by a tropical frugivore, the bonobo ( Pan paniscus ), and compared it with data derived from over 200 vegetation plots across their 50 km 2 + home ranges. We demonstrate that food species abundance estimates derived from the CCM are comparable to those derived from traditional vegetation plot sampling in less than 2 years of data collection, and agreement improved when accounting for aspects of consumer selectivity in objective vegetation plot sampling (e.g., tree size minima). Density correlated between CCM and plot‐derived estimates and was relatively insensitive to home range inclusion and other species characteristics, however, it was sensitive to sampling frequency. Agreement between the methods in relative distribution of resources performed better across species than expected by chance, although measures of dispersion correlated poorly. Once tested in other systems, the CCM may provide a robust measure of food availability for use in relative food availability indices and can be incorporated into existing observational data collection. The CCM has an advantage over traditional sampling methods as it incorporates sampling biases relevant to the consumer, thereby serving as a promising method for animal behavioral research.
