Abstract:
The proboscis monkey (Nasalis larvatus Wurmb, 1787) is an endemic primate of the island of Borneo that is protected and threatened with extinction. Deforestation is the biggest threat to proboscis monkeys because it destroys the ideal habitat for proboscis monkeys. The proboscis monkey’s habitat includes various types of forest such as wetland forest, peat forest, heath forest, rubber forest, and mangrove forest associated with water. The Tunan River is one of the proboscis monkey’s habitats outside the conservation area in the form of a forest that is fragmented apart by roads, residential areas, plantations, and ponds. Meanwhile, the spread of proboscis monkeys in the Tunan river forest fragmentation area, Waru District, North Penajam Paser Regency, East Kalimantan has never been reported so that a study is needed to determine its distribution. This research was started from January to February 2022. The data was collected using the boat survey method, namely observation by using a boat. The results obtained were twenty-four proboscis monkey distribution points based on direct observation. The distribution pattern of proboscis monkeys tends to be random in the fragmentation area and is found more in the upstream than downstream areas due to habitat conditions and the presence of forage trees that support the proboscis monkey population. Therefore, to preserve the proboscis monkey, it is necessary to provide information to the surrounding community by protecting the proboscis monkey habitat

Abstract:
Nature tourism park is a designation for landscapes that are protected through long-term planning, sustainable use and agriculture. These precious landscapes are preserved in their current state and promoted for tourism purposes. In the Bakut Island Nature Park, there are several groups of proboscis monkeys spread across the island, which are known as their natural habitat. Currently, the proboscis monkey, which is endemic to the island of Kalimantan, has received an endangered status after experiencing a population decline caused by the loss of the proboscis monkey's natural habitat. Currently, Bakut Island is one of the natural proboscis monkey conservation locations, but there is a natural tourism park that openly shows human activity at that location. This can affect the activity of proboscis monkeys in their survival. Responding to this, it is felt necessary to redesign the TWA which uses a concept that creates a relationship between humans and proboscis monkeys without directly involving the proboscis monkeys with the concept of Camouflage Architecture which hides human activity from the proboscis monkey's view and Biophilic Architecture in efforts to heal nature.

Abstract:
Despite saccades changing the image on the retina several times per second, we still perceive a stable visual world. A possible mechanism underlying this stability is that an internal retinotopic map is updated with each saccade, with the location of objects being compared before and after the saccade. Psychophysical experiments have shown that humans derive such location information from a corollary discharge (CD) accompanying saccades. Such a CD has been identified in the monkey brain in a circuit extending from superior colliculus to frontal cortex. There is a missing piece, however. Perceptual localization is established only in humans and the CD circuit only in monkeys. We therefore extended measurement of perceptual localization to the monkey by adapting the target displacement detection task developed in humans. During saccades to targets, the target disappeared and then reappeared, sometimes at a different location. The monkeys reported the displacement direction. Detections of displacement were similar in monkeys and humans, but enhanced detection of displacement from blanking the target at the end of the saccade was observed only in humans, not in monkeys. Saccade amplitude varied across trials, but the monkey's estimates of target location did not follow that variation, indicating that eye location depended on an internal CD rather than external visual information. We conclude that monkeys use a CD to determine their new eye location after each saccade, just as humans do.

AbstractForaging vocalizations given by Japanese and rhesus momkeys reared by their biological mothers differed from each other in a single parameter. Calls made by a Japanese monkey fostered by a rhesus female were dissimilar to those of conspecifics reared by their biological mothers, but similar to those of rhesus monkeys reared by their biological mothers, and the vocalizations given by rhesus monkeys fostered by Japanese monkey mothers were dissimilar to those of conspecifics reared by their biological mothers, but similar to those of Japanese monkeys reared by their biological mothers. Playback experiments revealed that both Japanese and rhesus monkeys distinguished between the calls of Japanese monkeys reared by their biological mothers and of the cross-fostered rhesus monkeys on one hand, and the vocalizations of rhesus monkeys reared by their biological mothers and of the cross-fostered Japanese monkey on the other hand. Thus, production of species-specific vocalizations was learned by each species, and it was the learned species-difference which the monkeys themselves discriminated.

Abstract:
A monkey forest tourism park is a tourist attraction whose function is to preserve the long tailed monkey’s (Macaca fascicularis) population and to benefit it as a tourist attraction. The research was taking place at the Monkey Forest Tourism Park/Taman Wisata Hutan Kera (TWHK) Bandar Lampung in Bandar Lampung City, Lampung Province, in November 2018. This study objective was to understand he interaction between monkeys and tourists influence the daily activities of long-tailed monkeys, by etermining the behavior of eating, resting, and moving. The dialy tourist presence was observed in order to analyse this impact to anaimal behavior. Observations in this research were carried out using the scan sampling method by observing and recording continuously the daily behavior over a certain period of time. The research was conducted in the period of time at 6:00 AM to 18:00 PM WIB with intervals observation time for 30 minutes for 14 consecutive days. The results showed 50% switching behavior, 31% resting, and 19% eating of all daily behavior. Factors that influence the most dominant behavior are the presence of natural food in TWHKis very small and the dependence of long-tailed monkeys to receive food from tourists. A long-tailed monkey’s natural food source at TWHK is the main factor influencing behavior change.The research implication is the enrichment of feed sources both type and amount of feed is important in TWHK

γ–Herpesviruses can be found in most primates including Old World an New World monkeys. The γ– herpesvirinae are grouped into two classes: lymphocryptoviruses (γ 1 ) and rhadinoviruses (γ 2 ). The lymphocryptoviruses include Epstein–Barr virus, lymphocryptovirus of rhesus monkeys, and Herpesvirus papio of baboons. Rhadinoviruses that infect New World monkeys include Herpesvirus saimiri , whose natural host is the squirrel monkey, and Herpesvirus ateles , which infects spider monkeys. Rhadinoviruses that infect hominoids and Old World monkeys include Kaposi's sarcoma–associated herpesvirus, also known as HHV–8, and rhesus monkey rhadinovirus.

Abstract:
1. The role of the thalamic ventroposterior medial (VPM) nucleus in the discriminative aspects of nociception and thermoreception was evaluated in alert, trained rhesus monkeys. Single-unit responses were recorded from VPM while the monkeys performed a battery of tasks involving noxious heat, innocuous cool, and air-puff stimuli presented to the face. The discriminative ability of the monkey was compared directly with the responses of single neurons, to determine whether the neuronal response could subserve the monkey's discriminative behavior. 2. Most thermally sensitive neurons exhibited multimodal properties. Only 18% responded exclusively to heat (HT-Heat neurons), whereas 27% responded to innocuous mechanical, as well as noxious mechanical and heat stimuli (WDR-Heat). Twenty-three percent responded to innocuous mechanical stimuli and innocuous skin cooling (Mechano-Cool), and 32% responded to mechanical, innocuous cool, and noxious heat stimuli (WDR-Heat-Cool). 3. Almost all mechanical receptive fields were confined to one division of the trigeminal nerve. This was true for all of the above categories of VPM neurons, even those showing highly convergent properties (WDR-Heat-Cool). 4. Heat-activated neurons produced graded responses to noxious skin heating in the 46 to 49 degrees C range. Stimulus-response functions of neurons that responded to both heat and cool did not differ from those of neurons that responded exclusively to skin heating. 5. When the monkeys were detecting small changes in the intensity of a noxious heat stimulus (e.g., from 47 to 47.1–47.8 degrees C), heat-activated neurons responded to the smallest temperature changes that could be detected by the monkeys. Further, there was a high correlation between the monkey's success in detecting the stimulus changes and the magnitude of the neuronal responses to those changes. 6. Although the responsiveness of VPM cool-activated neurons was not compared with the monkeys' threshold for detecting cooling changes, larger stimulus changes (2 degrees C) that the monkey reliably detected produced significant neuronal responses. Further studies are needed to determine whether VPM neurons respond to the smallest detectable changes in skin cooling. 7. Several thermally sensitive VPM neurons were tested under two attentional conditions: 1) while the monkey was required to attend to a visual stimulus, and 2) while it was required to attend to the thermal stimulus to obtain reward. None showed a significant difference in heat- or cool-evoked activity in the two attentional states.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract:
AbstractTwo genera of nonhuman primates that include howler monkeys (Alouatta palliata and Alouatta pigra) and spider monkeys (Ateles geoffroyi) currently are located throughout the Maya region. It has been suggested that the Classic Maya associated these monkeys, especially howler monkeys, with the arts. This view is exemplified in the Popol Vuh and in depictions of monkey-man scribes on Late Classic (c. a.d. 550–900) ceramics. This paper provides evidence that a third genus, the capuchin monkey (Cebus capucinus), is also located in the southern Maya region and may have extended as far north as Belize within the last century. Supporting data are drawn from historic accounts, artifact and faunal analysis, and linguistic data. It is also proposed, based on an interspecific comparison of morphological and behavioral characteristics, that capuchin monkeys rather than howler monkeys are the animals represented in depictions of monkey scribes.

Abstract:
Abstract Cloning of macaque monkeys by somatic cell nucleus transfer (SCNT) allows the generation of monkeys with uniform genetic backgrounds that are useful for the development of non-human primate models of human diseases. Here, we report the feasibility of this approach by SCNT of fibroblasts from a macaque monkey (Macaca fascicularis), in which a core circadian transcription factor BMAL1 was knocked out by clustered regularly interspaced short palindromic repeat/Cas9 gene editing (see accompanying paper). Out of 325 SCNT embryos transferred into 65 surrogate monkeys, we cloned five macaque monkeys with BMAL1 mutations in both alleles without mosaicism, with nuclear genes identical to that of the fibroblast donor monkey. Further peripheral blood mRNA analysis confirmed the complete absence of the wild-type BMAL1 transcript. This study demonstrates that the SCNT approach could be used to generate cloned monkeys from fibroblasts of a young adult monkeys and paves the way for the development of macaque monkey disease models with uniform genetic backgrounds.

Abstract:
Rhesus monkeys Macaca mulatta and people have coexisted for many years in Vrindaban in Mathura District, Uttar Pradesh, India. The monkeys are highly valued both by locals and pilgrims to the area, in part because of their quasi sacred status, but during the last two decades the increasing human and monkey populations of the township have led to severe human-monkey conflict and a decrease in people's respect for the monkeys. To ease this situation one of the world's largest ever translocations of monkeys was undertaken. In 1995, 30 groups of rhesus monkeys, comprising an estimated 1,338 individuals, were recorded in Vrindaban. Of these, 12 groups, a total of 600 individuals, were translocated in January 1997 to eight sites in seminatural forested areas within the same District. A post-translocation study indicated that the translocated monkeys were settled and appeared to be exhibiting normal behaviour. This study indicates that translocation of commensal monkeys to forested areas can be a successful technique for their rehabilitation.

Abstract:
Six young and six old squirrel monkeys were tested on two different short-term memory tasks. One was a two-choice problem, the other a nine-choice problem. A baseline, or one-choice, problem was also included. A video camera recorded all behaviors displayed by the monkeys during testing. Behaviors coded were turning, aggression, displacement, exploratory, huddling, orienting, locomotion, screen activities, and visual scanning. Also recorded was correct or incorrect choice and whether the animal showed evidence of seeing the cue stimulus. Old animals committed more errors during both phases of the experiment. Older animals were also more likely to engage in active behaviors, such as turning, whereas young animals were more likely to manifest less active behaviors, such as visual scanning and orienting. Young animals were also more likely to see the stimulus. A path analytic procedure was used to determine direct effects of age on performance and indirect effects mediated through behaviors manifested prior to the choice. For the two-choice problem, approximately half of the age effects on performance were attributable to indirect effects. For the nine-choice problem almost three quarters of the age effects on performance were attributable to indirect effects. These findings indicate that age differences in short-term memory performance are not direct effects of age alone. The age effect also occurs because age affects the behaviors of the monkeys and that these behaviors have a large effect on subsequent memory performance.

Abstract:
I studied free-ranging vervet monkeys (Chlorocebus aethiops) in South Africa using focal animal sampling to test current theories of reproduction and maternal investment. Mothers cope with the energetic costs of lactation by feeding more than non-lactating females and targeting higher nutrient quality items as their infant ages. The dynamic nature of mother-infant interactions is highlighted, with infants spending less time in contact while the mother is moving and foraging. Other troop members “allomother” the infant primarily in the infant’s first couple of months. The length of investment is explored, with greater length of interbirth interval in low nutrient quality environments, larger troop sizes and higher survival rates. Maternal dominance rank and infant sex significantly influenced time in ventral contact, with low-ranking daughters spending more time in contact than high-ranking daughters. The findings from this thesis highlight the complex interaction of ecological and social conditions on maternal investment.

Abstract:
This study explores the effect of changing ecological conditions on female social organization among free-ranging vervet monkeys (Cholorocebus aethiops pygerythrus) in the Klein Karoo, South Africa. Comparison was made between a previous study conducted during a period of drought in 2009, and my own study conducted when conditions were much wetter and hence, less ecologically stressful. In addition, animals in the present study also experienced conditions of low demographic stress. Compared to 2009, females displayed lower rates of competition and aggression, did not compete for access to grooming partners, and did not preferentially groom those of high rank, nor did they do so more frequently. Females did, however, preferentially associate spatially with those they groomed most; a finding in contrast to the previous study. Females did not groom those of adjacent ranks more frequently, nor was there any relationship between rank difference and spatial association. In addition, there were rank differences in vigilance were found between females, and vigilance costs overall were affected by total group size. Overall, these findings support some aspects of the socioecological model used to predict group structure in primates, but other aspects of social organization remain puzzling, and may reflect larger overall group sizes in the Samara population, which changes patterns of engagement between females in ways not fully captured by current models.

Abstract:
Food cleaning behavior has been observed among laboratory squirrel monkeys. A Wilcoxon signed-ranks test showed that significantly more cleaning behavior occurred when hard monkey chow pellets and soft fruit were coated with edible debris. Monkeys removed fewer pieces of fruit from a food crock containing fruit coated with edible debris in a timed test. A principal component analysis of the food cleaning behaviors showed two underlying correlated factors. The first factor was the use of the body to clean food. The second factor was the use of the environment to clean food. Two groups of squirrel monkeys, one without previous learners and one with previous learners, were subjects in a fishing study. The presence of previous learners in the social group was not significant for monkeys fishing in water filled crocks. But there was a significant difference in the number of fishing attempts made by the No Previous Learners Group when fishing in wading pools. The Previous Learners group did not make significantly more fishing attempts fishing in wading pools than in crocks. A significant difference was observed in fishing attempts during Phase 1 and Phase 2 of the wading pool experiment for both groups. All monkeys in the group fishing experiments ate fish when it could be obtained. Monkeys who did not learn to fish successfully learned alternative behaviors to obtain fish. The Previous Learners group in the wading pool experiment were subjects in a more difficult fishing test. Significantly fewer fishing attempts were made but the number of monkeys that caught fish was larger. Caged squirrel monkeys scored a lower percentage of fishing attempts than squirrel monkeys living in a social group. While Cebus monkeys caught fish, unlike squirrel monkeys, they did not attempt to eat them.

Full text
Abstract:
Many studies have documented adverse affects to inequitable situations in non-human primates. The behaviors that have predominantly been examined include food taking, collecting, giving, and refusals between the primate subjects and the experimenters. However, no studies had looked at the affective responses to inequity in primates. In a recent study, four-year old children who were rewarded inequitably accepted the reward, however they showed affective signs of dissatisfaction. For this study, we looked for affective displays in capuchins during inequitable exchange tasks. We predicted that the capuchins that were experiencing inequity would show more signs of agitation and aggression than those in equitable situations. We saw no increase in agitation or aggression when subjects were treated inequitably. There was higher aggression towards partners who received the lower reward in inequitable situations and less agitation seen by partners during frustration controls. Future studies may find our hypothesized results using different methodologies.

Abstract:
Studies on accommodation in monkeys suggest that accommodation is caused by a pressure differential between the anterior and vitreous chambers of the eye. Our subjects were six adult male pigtail monkeys. This animal was chosen because it has strong eye-contact behavior to control his accommodation. Each subject had a radiosonde pressure transducer implanted in the vitreous chamber of one eye. The transdicer was activated by a radio-frequency source taped to the skull above the eye. The unit was calibrated by putting the unit (attached to the monkey) into a pressure chamber and elevating the pressure. The first two monkeys were restrained in a chair and were alert because no drugs were used. The other four were not familiar with a restraining chair. For this reason we used ketamine anesthesia, along with eserine, to induce accommodation. At 20 ft (6.1 m) from the monkey's eyes the caretaker developed eye contact with the monkey. The caretaker then slowly walked to within 1 ft (30.6 cm) of the monkey's eyes while the pressure steadily increased. The caretaker then backed away to 20 ft (6.1 m) and the signal returned to its starting point. The results on the four monkeys under anesthesia and eserine support the findings from the first group.

Abstract:
Recent anatomical experiments in macaque monkeys have identified the presumed cortical pathway for motion processing. Using a combination of psychophysical, recording, and lesion techniques our laboratory has begun to investigate the types of motion processing that occur at each cortical level in this pathway. Our psychophysical experiments show that monkeys and humans have similar thresholds for perceiving shear motion and 2- and 3-D structures from motion. These experiments also show that the monkey and human nervous systems integrate motion information across both space and time to form neural representations of 3-D surfaces. Restricted ibotenic acid-induced cortical lesions to the middle temporal area (area MT) of macaque monkeys produced increased thresholds for the perception of both shear motion and structure from motion. These deficits were restricted to that part of the visual field that corresponded to the locus of the lesion within the retinotopic representation in area MT. The deficits appeared to be specific to motion perception since contrast sensitivity thresholds were not affected by the lesions. Interestingly the shear motion thresholds recovered in 3–4 days. This result suggests that either there has been a reorganization of the retinotopic map within regions of area MT that were not damaged or parallel motion pathways have been recruited or strengthened during the recovery period.

Abstract:
The effect of hormone treatment on the material properties of ligaments has been extensively studied for the anterior cruciate ligament (ACL). However, there have been very few studies on the effects of hormones on the material properties of the shoulder. These shoulder ligaments contribute to overall shoulder stability, and a change in ligament properties could contribute to a change in overall shoulder laxity. This study uses female cynomologus macaque (Macaca fascicularis) monkeys as an animal model of the human shoulder to determine if estrogen has an effect on the viscoelastic properties of the anterior pouch of the inferior glenohumeral ligament (IGHL). Cynomolgus monkeys have served as nonhuman primate models in several studies, including monkey models of menopause, the effects of hormone replacement therapy on the cardiovascular system, reproductive support organs, and the knee joint. The cynomolgus macaques are commonly used for studies involving hormone replacement therapy because they have 28-day menstrual cycles with very similar hormonal patterns to that of women.

Abstract:
In spite of the fact that the computing architecture of the brain is massively parallel, our ability to process incoming sensory information in parallel is surprisingly limited. It is not possible, for example, to recognize within the same instant more than one or two objects in a crowded scene. Thus, much of the information impinging on the retina must be filtered out centrally, a process usually termed attention. To understand how this comes about, we have recorded from neurons in visual areas of monkey extrastriate cortex known to underlie object recognition. We have found that selective attention serves to remove irrelevant information from the receptive fields of extrastriate neurons and sharpen their selectivity for visual features such as orientation or color. These effects of attention may explain both why we have little awareness of unattended stimuli, and why our resolution of spatial location and visual features is improved inside the focus of attention. Our behavioral studies in monkeys suggest that attention controls visual processing via signals from the lateral pulvinar nucleus of the thalamus.
