The role of Local Ecological Knowledge on the Behavioral Ecology of mammals
While the role of Local Ecological Knowledge (LEK) is widely recognized for its dialogue and complement in ecology and conservation contexts, its role on the behavioral ecology of mammals is still unknown. With that in mind, we investigated LEK on the behavioral ecology of mammals, and which variables could influence such knowledge. The study was carried out in the municipality of Cabaceiras, state of Paraíba, Brazil. Data collection was divided …
Revisiting Infanticide in Non‐Human Primates Reveals a Similar Likelihood of Male and Female Perpetrators
Infanticide is understood as any direct or indirect behavior that fatally harms an infant, regardless of whether the perpetrator gains benefits. In non‐human primates, males are frequently identified as the perpetrators. Classical studies categorized behaviors like “abuse”, “fatal neglect”, “kidnapping”, and “aunting to death” as forms of infanticide when they resulted in infant death. However, in more recent literature, some of these behaviors a…
Environmental anchoring as a tool for a more conscious tourism
Anchoring is a cognitive process in which individuals use an initial reference point to make quick judgments or decisions. We investigated its applicability in nature tourism, specifically in dolphin-watching tours using motorboats, an activity with high tourist demand but known negative impacts on wildlife. To test the anchoring effect, we applied an informative text about the harmful consequences of motorboats on dolphin well-being. We conducte…
Interactions between Cetaceans (suborder Odontoceti) and Artisanal Fishing in Brazil
Studies based on the relationship between humans and the natural environment have been proven to be important tools for understanding the influence, knowledge, and perceptions associated with the web of interactions between humans, species and ecosystems. Here, we highlight the interactions between cetaceans and artisanal fishing. Thus, this study aimed to: a) compile studies that consider artisanal fishing and its interactions with small cetacea…

Visitors’ perception when participating in a poorly planned ecotourism activity
The present study aimed at assessing the environmental perception of tourists about the impacts of an onboard excursion into nature, referred as an ecotourism activity. We interviewed 347 tourists after they attended a dolphin-watching activity at the Pipa Beach located within a protected area in Northeastern Brazil. We gathered socioeconomic information, such as gender, age, income, and schooling as well as tourists’ perceptions about positive o…
Self‐medication in nonhuman primates
Animal self‐medication is thought to provide an adaptive advantage, as species would actively respond to a disease state or homeostatic imbalances. In wild nonhuman primates, it is challenging to differentiate plant use as part of the diet or as medication, especially because self‐medication can be preventive or therapeutic. Here, we aimed to compile the available potential evidence on primate self‐medication modes, investigating which proposed r…
Like Music to our Ears
It is known that bird vocalizations and music share acoustic similarities. Unsurprisingly, bird sounds inspired a number of music composers. In music, complexity plays an important role in auditory attractiveness. Would sound complexity also be important to explain the attractiveness of bird vocalizations to humans? In our study, we experimentally assessed the preference for vocalizations according to their level of complexity, indicated by objec…
Temporal consistency and ecological validity of personality structure in common marmosets ( Callithrix jacchus )
Personality in animals has been extensively researched in recent decades. Temporal consistency of behaviors is almost always part of the personality definition and is usually explored in several different testing sessions or observation periods. However, it is still unclear whether the obtained personality constructs are stable across several years, which might be especially important for long‐living animals, such as primates. Further, little is …
Fermented food consumption in wild nonhuman primates and its ecological drivers
OBJECTIVES: Although fermented food use is ubiquitous in humans, the ecological and evolutionary factors contributing to its emergence are unclear. Here we investigated the ecological contexts surrounding the consumption of fruits in the late stages of fermentation by wild primates to provide insight into its adaptive function. We hypothesized that climate, socioecological traits, and habitat patch size would influence the occurrence of this beha…
The Anchoring Model as a Tool to Improve Visitors' Perceptions of Zoos
Visitors' negative perceptions about the quality of life of animals exhibited in zoos has been of great importance to induce a positive transformation of these establishments in a number of countries. However, this is a slow process, commonly associated with an improvement in the general education of society. The present study aimed to investigate whether the anchoring model can play a role in rapidly changing people's perceptions about the poor …
Wild common marmosets (Callithrix jacchus) employ spatial cognitive abilities to improve their food search and consumption
From exploitation to conservation
Currently there are many interfaces that allow the relationship between humans and animals, including zoos. Throughout history, the change in zoo structure has accompanied the social and cultural changes of human society. Nevertheless, despite the remarkable progress since early zoos were organized, there is still a great need for improvements of zoos around the world. A critical look at the relationship between humans and animals that led to the…
Detection of insect prey by wild common marmosets
Most species of New World primates have an unusual color vision pattern that can affect an individual's ability to detect food. Whereas males can only be dichromatic, females can be either dichromatic or trichromatic. Trichromats are expected to have an advantage in detecting conspicuous food whereas dichromats should be better at locating cryptic resources. Here we aimed to understand how color vision phenotype influences insect foraging by five…
Balancing contest competition, scramble competition, and social tolerance at feeding sites in wild common marmosets ( Callithrix jacchus )
Models of primate sociality focus on the costs and benefits of group living and how factors such as rank, feeding competition, alliance formation, and cooperative behavior shape within‐group social relationships. We conducted a series of controlled field experiments designed to investigate how resource distribution (one or three of four reward platforms) and amount of food on a reward platform affected foraging strategies and individual feeding s…
Trait variation and trait stability in common marmosets ( Callithrix jacchus) inhabiting ecologically distinct habitats in northeastern Brazil
Understanding the set of factors that promote and constrain a species’ ability to exploit ecologically distinct habitats is central for addressing questions of intraspecific variability in behavior and morphology. In this study, we compared newly collected data with published data on body measurements, group size and composition, daily path length, home range, and reproductive output in wild common marmosets naturally inhabiting two contrasting e…
People's perception on animal welfare
Understanding peoples' perception on animal welfare is vital to promote people awareness and changes in attitudes towards this subject. Here we present a short review on public perception of animal welfare in different instances and the factors influencing each one of them. While the great public concern towards farm and laboratory animals resulted in increased efforts to assess animal welfare in these instances, less attention has been given to …

Adaptability in stone tool use by wild capuchin monkeys ( Sapajus libidinosus )
Capuchin monkeys are well known for population variation in the use of stone tools and the types of food items consumed. In order to determine adaptability in stone tool use, we investigated a never before studied population of wild capuchin monkey (Sapajus libidinosus) displaying terrestrial habits in a Caatinga environment. To carry out this study we recorded physical evidence of the use of stone tools as well as made direct observations throug…
Camera Trap Observations of Nonhabituated Critically Endangered Wild Blonde Capuchins, Sapajus flavius (Formerly Cebus flavius)
The effect of habitat acoustics on common marmoset vocal signal transmission
Noisy acoustic environments present several challenges for the evolution of acoustic communication systems. Among the most significant is the need to limit degradation of spectro-temporal signal structure in order to maintain communicative efficacy. This can be achieved by selecting for several potentially complementary processes. Selection can act on behavioral mechanisms permitting signalers to control the timing and occurrence of signal produc…
