Book Description
Primates are confronted with threats of predation on a regular basis, but much is unknown regarding how they perceive and respond to these threats. Even less is known about how predators respond to primate anti-predator behaviors. Thus, key questions remain: How do primates cope with the possibility of being eaten and do these coping strategies thwart hunting by predators? This dissertation investigates these questions using a newly identified primate species, Rylands’ bald-faced saki monkeys (Pithecia rylandsi), one of their main felid predators, ocelots (Leopardus pardalis), and audio and visual simulations of other predators. Specifically, I conducted experiments on wild saki monkeys in the Peruvian Amazon using audio playbacks of predator vocalizations and life-size decoys of their main aerial and terrestrial predators. I also carried out playback experiments on the predators themselves using audio broadcasts of monkey alarm calls. This experimental design allowed me to test the ability of sakis to recognize predators based on acoustic and visual cues, determine how they respond based on predator class, location, and context, as well as to examine what information might be conveyed in their alarm calls and how these calls cause changes to predator behavior. Results from playbacks show that sakis are able to identify predator types (aerial vs. terrestrial) based solely on vocalizations, but they do not exhibit predator-specific escape responses to terrestrial predators based on acoustic cues alone. While sakis respond to harpy eagle shrieks appropriately by descending the canopy, they exhibit no clear movement patterns upon hearing jaguar growls. In contrast, visual jaguar models consistently elicit fast approaches, mobbing-style responses, and long alarm calling bouts. Visual harpy eagle stimuli elicit predator-specific whistle calls that are brief and quiet in nature, characteristics that make them difficult to locate in the forest matrix. Additionally, whistle calls are most often accompanied by escape behaviors. Thus, these calls are likely used to alert conspecifics to raptor presence while simultaneously avoiding advertisement of the caller’s location. Sakis respond to ocelot models with long bouts of chipper calls that are interspersed by periodic chucks and growls. These calls are noisy and chaotic, with call features that make them easily locatable. Playbacks conducted on radio-collared ocelots show that chipper calls function as deterrent signals by causing ocelots to leave the area. Lastly, visual experiments show that sakis are able to discriminate dangerous from non-dangerous snakes and appear to adjust the intensity of their responses according threat level. This dissertation contributes the first systematic and experimental data on risk perception, anti-predator behaviors, and alarm call usage in Pithecia rylandsi, a little-known pitheciine species. Furthermore, this is the first experimental evidence using playbacks to show that wild ambush predators in naturalistic conditions are deterred by prey alarm calls. By incorporating data on both primate responses to predator stimuli and predator response to primate alarm calls, this research takes a rarely applied dual approach to the investigation of alarm call function. My findings also elucidate the need to more carefully consider the effects of sensory mode on primate anti-predator responses.

Book Description
This will be the first time a volume will be compiled focusing on South American monkeys as models to address and test critical issues in the study of nonhuman primates. In addition, the volume will serve an important compliment to the book on Mesoamerican primates recently published in the series under the DIPR book series. The book will be of interest to a broad range of scientists in various disciplines, ranging from primatology, to animal behavior, animal ecology, conservation biology, veterinary science, animal husbandry, anthropology, and natural resource management. Moreover, although the volume will highlight South American primates, chapters will not simply review particular taxa or topics. Rather the focus of each chapter is to examine the nature and range of primate responses to changes in their ecological and social environments, and to use data on South American monkeys to address critical theoretical questions in the study of primate behavior, ecology, and conservation. Thus, we anticipate that the volume will be widely read by a broad range of students and researchers interested in prosimians, New World monkeys, Old World monkeys, apes, humans, as well as animal behavior and tropical biology.

Book Description
The selective pressures exerted on primate populations from threat of predation have led to numerous behavioral and morphological adaptations that allow for pre-emptive detection and evasion of predators. Predators evolve counterstrategies, and an arms race is born. Anti-predator strategies are costly, in the sense that employing them may divert energy from activities more directly related to fitness, such foraging or mating. Therefore, one would expect higher frequencies of more severe anti-predator behaviors to be expressed by primates who have regular interactions with potential predators, because temporal allocation of those behaviors would be reinforced. A snapshot of natural primate populations reveals that predation is often a substantial source of mortality. Here I investigate the anti-predator strategies of eight sympatric primates in Suriname, South America, to examine how astute wild primates are at detecting predators by only audio cues, how strategies vary by taxa, and whether these strategies vary depending on level or perception of risk within a location. The results suggest that neotropical primates can identify predators as such by vocalizations alone, that anti-predator strategies are highly variable, and that some degree of experience and reinforcement is required for an appropriate level of response behavior. Further, primates in the neotropics appear to evaluate the relative safety of their surroundings and make decisions based on them when confronted with the perceived presence of predators.

Book Description
In this dissertation, I investigate primate anti-predator behavior toward snakes. In particular, I examine: 1) how differences in evolutionary history with venomous snakes in lemuriforms, platyrrhines, and catarrhines are reflected in differential ability to detect snakes at a distance; 2) whether mobbing and monitoring snakes interfere with daily activities, or can be undertaken without affecting daily activities, and; 3) if rhesus macaques (Macaca mulatta) use the postural cues of snakes to assess their potential threat. The Snake Detection theory proposes that predation by snakes has influenced the neural organization of primate visual systems on different continents over evolutionary time. I tested the ability to detect snakes at a distance in species from Madagascar, South America, and Asia, and found that, consistent with the prediction, rhesus macaques detected snake models at the farthest distance, squirrel monkeys (Saimiri sciureus) only responded when snake models were close, and black-and-white ruffed lemurs (Varecia variegata) never responded to the models. Predator monitoring is generally thought to interfere with normal daily activities, but I found that rhesus macaques did not significantly decrease baseline activities while monitoring a model snake. These findings suggest that snakes may be the only primate predator that can be monitored with little cost, and I argue that it results from the unique hunting style of snakes. Primates are known to vary in their responses toward different types of snakes or snakes in different contexts. One possible explanation is that primates are responding to the threat level presented by the snake. One way to interpret the intentions of a snake is through its posture. Using models of snakes in different postures, I found that rhesus macaques respond more strongly to snakes in striking pose relative to a coiled posture, and more to coiled posture than to traveling snakes, consistent with what is known of snake behavior. In addition, I found that a partially covered snake evoked a response comparable to that of the striking snake. My research contributes to the study of anti-predator behavior by investigating primate behavior in relation to predators at a finer level than had previously been conducted. By recognizing the unique hunting style of snakes and their biogeographical history, this dissertation highlights the subtle effects of snakes on primate anti-predator behavior on both ecological and evolutionary time scales.

Book Description
The classic literature on predation dealt almost exclusively with solitary predators and their prey. Going back to Lotka-Volterra and optimal foraging theory, the theory about predation, including predator-prey population dynamics, was developed for solitary species. Various consequences of sociality for predators have been considered only recently. Similarly, while it was long recognized that prey species can benefit from living in groups, research on the adaptive value of sociality for prey species mostly emerged in the 1970s. The main theme of this book is the various ways that predators and prey may benefit from living in groups. The first part focusses on predators and explores how group membership influences predation success rate, from searching to subduing prey. The second part focusses on how prey in groups can detect and escape predators. The final section explores group size and composition and how individuals respond over evolutionary times to the challenges posed by chasing or being chased by animals in groups. This book will help the reader understand current issues in social predation theory and provide a synthesis of the literature across a broad range of animal taxa. Includes the whole taxonomical range rather than limiting it to a select few Features in-depth analysis that allows a better understanding of many subtleties surrounding the issues related to social predation Presents both models and empirical results while covering the extensive predator and prey literature Contains extensive illustrations and separate boxes that cover more technical features, i.e., to present models and review results
