“…While most robust capuchin (Sapajus) species have been documented to use tools in the wild at least anecdotally, wild gracile capuchin (Cebus) species have been observed to do so much less frequently (Barrett et al, 2018;Boinski, 1988;Chevalier-Skolnikoff, 1990;Monteza-Moreno et al, 2020;Panger et al, 2002;Panger, 1998;Perry et al, 2017;Phillips, 1998), pointing to significant diversity in types of tool use actions and frequency of tool use performed across the capuchin radiation by different species. Of the robust capuchins, Sapajus libidinosus, the bearded capuchin or black-striped capuchin, is the best documented tool-using species with the most diverse tool use repertoire in the wild; some populations even exhibit habitual stone tool use for hammering (Falótico et al, 2017(Falótico et al, , 2018(Falótico et al, , 2019Presotto et al, 2020;Visalberghi et al, 2015). In addition, a limited number of bearded capuchin populations have been documented to use tools for digging, probing, throwing as a sexual display, and for displaying aggressiveness in the wild (Falόtico & Ottoni, 2014;Mannu & Ottoni, 2009;Moura & Lee, 2004, 2010; Table 1).…”

Primate tool use is of great interest but has been reported only in a limited number of species. Here we report tool use in crested capuchin monkeys (Sapajus robustus), an almost completely unstudied robust capuchin species. Crested capuchins and their sister species, the yellow‐breasted capuchin, diverged from a common ancestor over 2 million years ago, so this study fills a significant gap in understanding of tool use capacity and variation within the robust capuchin monkey radiation. Our study group was a captive population of seven individuals at the Santa Ana Zoo in California. The monkeys were given no prior training, and they were provided with a variety of enrichment items, including materials that could be used as tools as well as hard‐to‐access resources, for open‐ended interactions. In 54 observation hours, monkeys performed eleven tool use actions: digging, hammering, probing, raking, sponging, striking, sweeping, throwing, waving, wedging, and wiping. We observed tool modification, serial tool use, and social learning opportunities, including monkeys' direct observation of tool use and tolerated scrounging of foods obtained through tool use. We also observed significant individual skew in tool use frequency, with one individual using tools daily, and two individuals never using tools during the study. While crested capuchins have never been reported to use tools in the wild, our findings provide evidence for the species' capacity and propensity for tool use, highlighting the urgent need for research on this understudied, endangered primate. By providing detailed data on clearly identified S. robustus individuals, this study marks an effort to counteract the overgeneralization in the captive literature in referring to any robust capuchins of unknown provenance or ancestry as Cebus apella, a practice that obfuscates potential differences among species in tool use performance and repertoire in one of the only species‐rich tool‐using genera in the world.

“…Many animal phyla and species use mangrove forests, such as molluscs, arthropods, fishes, reptiles, birds, and mammals (Giesen et al 2006). For example, sixty-seven primate taxa, most of them exhibiting rare behaviors shelter or feed in tropical and subtropical mangroves (Supriatna & Wahono 2000, Santos et al 2019, Presotto et al 2020. The high productivity rates of mangrove ecosystems are crucial for the benthic and pelagic components of neritic food webs (Robertson et al 1992), providing direct and indirect resources (Tomlinson 1986, Luther & Greenberg 2009 for transient fishes and crustaceans as nursery and foraging habitats (El-Regal & Ibrahim 2014, Hutchison et al 2014, Sheaves 2017, Litvin et al 2018.…”

Brazilian mangroves at risk

Recent statements from the Brazilian federal government indicate that impacting economic activities, particularly commercial shrimp farming, are being encouraged in mangrove areas in the near future. Alterations of the National Action Plan and legal instruments that partially protected mangrove ecosystems have created an even weaker legal framework than previously existed. Such changes are leading Brazil far from the global call to conserve mangroves and from the Aichi targets and United Nations Sustainable Development Goals. Unfortunately, the loss of mangrove ecosystems and their ecosystem services will negatively impact living standards for Brazilians in coastal areas.

“…It is known that Nasalis larvatus has its primary habitat within mangrove forests. Other NHPS mangrove forest relationships are noted, such as the critically endangered Piliocolobus kirkii [42,43] and Piliocolobus epieni [44,45], as well as two capuchin species, the toolusing capuchin species, Sapajus libidinosus [11,46] and S. apella [47]. In contrast, the global status of the relationship between all NHPS and mangrove forests remains unknown or has limited documentation.…”

Establishing the relationship between non-human primates and mangrove forests at the global, national, and local scales

Global and spatially explicit information about the interaction between habitat and wildlife species is critical to enhancing conservation efforts. Despite the recognized importance of mangrove forests to non-human primates, the relationship between the two lacks understanding. To counter this, we created the MangPrim-21 database to map and measure the locations of interactions between all non-human primates and all mangrove forests globally. We report our findings across the global, national, and local scales for all inventoried non-human primates and all inventoried mangrove forests. Globally, we find that half of all non-primates potentially use mangrove forests, and more than half of the global mangrove forest falls within the delineated range of at least one non-human primate species. Nationally, we find that Indonesia, Madagascar, Brazil, Cameroon, and Malaysia likely have the most non-human primate and mangrove forest interactions. At the subnational level, we find that several discrete locations in Kalimantan are critical to both mangrove forests and non-human primates. The MangPrim-21 database provides a globally consistent and locally applicable database of non-human primate and mangrove forest interactions. The results presented have broader implications for non-human primate and mangrove conservation and global actions to protect both. Additionally, our results raise questions about the idea that non-human primates primarily use mangrove forests as a refuge from human encroachment and habitat degradation.
