Kecacingan sering menginfeksi primata terutama yang di pelihara secara eksitu. Infeksi cacing menimbulkan kesakitan dan ketidaknyamanan pada primata dan dapat menularkan ke manusia (zoonosis). Penelitian ini bertujuan untuk mengetahui jenis cacing saluran pencernaan dan prevalensinya pada primata di Pusat Rehabilitasi Primata Jawa.

Abstract:

Environmental stress on primate populations can take many forms. Abiotic factors, such as temperature and precipitation, may directly influence the behavior of primates owing to physiological demands of thermoregulation or through indirect influences on vegetation that primates rely on for food. These effects can also scale up to the macro scale, impacting primate distributions and evolution. Primates also encounter stress during interactions within and between species (i.e., biotic interactions). For example, selective pressure from male-perpetrated infanticide can drive the development of fe

With 60% of all primate species now threatened with extinction and many species only persisting in small populations in forest fragments, conservation action is urgently needed.

Here we argue that restoration of primate habitat will be an essential component of strategies aimed at conserving primates and preventing the extinctions that may occur before the end of the century and propose that primates can act as flagship species for restoration efforts.

In consequence, debate has tended to focus on whether a given trait can be interpreted as evidence of nocturnal or diurnal behavior in the primate fossil record.

Recent articles on primate articulatory abilities are revolutionary regarding speech emergence, a crucial aspect of language evolution, by revealing a human-like system of proto-vowels in nonhuman primates and implicitly throughout our hominid ancestry. This article presents both a schematic history and the state of the art in primate vocalization research and its importance for speech emergence. Recent speech research advances allow more incisive comparison of phylogeny and ontogeny and also an illuminating reinterpretation of vintage primate vocalization data.

Abstract:

The anatomy of the nonhuman primate vocal tract is not fundamentally different from the human one. Notwithstanding, nonhuman primates are remarkably unskillful at controlling vocal production and at combining basic call units into more complex strings. Instead, their vocal behavior is linked to specific psychological states, which are evoked by events in their social or physical environment. Humans are the only primates that have evolved the ability to produce elaborate and willfully controlled vocal signals, although this may have been a fairly recent invention. Despite their expressive limit

Abstract:

The primate species of Bangka Belitung such as Mentilin are categorized as endangered species and are constantly under threat as a result of poaching and habitat destruction. Various conservation efforts have been carried out, one of which is by touching the aspect of public education. However, there has been no specific research on the community's response to primate conservation in Bangka Island. This study aimed to determine the level of public knowledge of primates typical of Bangka Belitung and to determine public perceptions of conservation efforts for primates typical of Bangka Belitung

Abstract:

When the diminutive skeleton of Homo floresiensis was found on the Indonesian island of Flores, it was interpreted as an island dwarf, conforming to the ‘island rule’ that large animals evolve smaller size on islands, but small animals tend to get larger. However, previous studies of the island rule have not included primates, so the extent to which insular primate populations undergo size change was unknown. We use a comparative database of 39 independently derived island endemic primate species and subspecies to demonstrate that primates do conform to the island rule: small-bodied primates t

Abstract:

Four genera of primates are present in the early to mid-Duchesnean Lac Pelletier Lower Fauna. Phenacolemur leonardi sp.nov., Trogolemur sp., Omomys sp., and Macrotarsius cf. M. montanus make up the latest diverse primate assemblage known from North America and from the Great Plains. This primate assemblage is similar to the earliest Duchesnean assemblage from the Wood locality, Badwater Creek area of central Wyoming, and primate genera appear to have been widely distributed through the Great Plains and Rocky Mountains in the Uintan–Duchesnean.

Currently, ~65% of extant primate species (ca 512 species) distributed in 91 countries in the Neotropics, mainland Africa, Madagascar, South Asia and Southeast Asia are threatened with extinction and 75% have declining populations as a result of deforestation and habitat loss resulting from increasing global market demands, and land conversion for industrial agriculture, cattle production and natural resource extraction. Other pressures that negatively impact primates are unsustainable bushmeat hunting, the illegal trade of primates as pets and as body parts, expanding road networks in previou

We therefore need to establish population densities in both unprotected and protected areas to effectively inform conservation planning. The Greater Mahale Ecosystem in western Tanzania is a region of mixed protected status with seven cercopithecine and colobine species: blue (Cercopithecus mitis doggetti), red-tailed (C. ascanius schmidi), and vervet (Chlorocebus pygerythrus) monkeys; ashy red colobus (Piliocolobus tephrosceles); black-and-white colobus (Colobus angolensis); a

Guinea-Bissau (GB) is a regional stronghold for primate conservation. Ten primates occur in the country, including the Western chimpanzee (<em>Pan troglodytes verus</em>) and two colobus monkeys (<em>Colobus polykomos</em> and <em>Piliocolobus badius temminckii</em>). Primate meat is consumed at households and bushmeat-dedicated establishments, locally named "Abafatório". Such establishments are mentioned to be common in urban areas since the 1980s and to be specialized in serving primate meat while drinking alcoholic beverages. The meat is typically cooked in a stew and eaten with bread. Howe

Our research goal was to investigate the primate pet trade in the United States. While dogs and cats are the most common type of pet, there are an estimated 15,000 pet primates in the United States and the demand for exotic pets in general has been rising. Most research on pet primates occurs in habitat countries and little is known about these pets in the United States. We collected data from six exotic pet-trade websites twice a month for 12 months. We recorded the type of primate for sale, sex, age, location, and price. We used Chi-Square Goodness-of-Fit tests to compare whether the number

Here, we investigate sex differences in the relative size of the cerebellum, a region that has played a major role in primate brain evolution and that has been associated with cognitive abilities that may be subject to sexual selection in primates. Methods: We compiled individual volumetric and sex data from published data sources and used MCMC generalized linear mixed models to test for sex effects

Abstract:

Litter size plays an essential role in mammalian evolution and is one of the most important factors determining whether an organism is deemed to have a ‘slow’ or ‘fast’ life history strategy. Humans are distinct in being classified as having slow life history yet bearing singletons who have completed relatively less growth than other ape neonates. Previous work has proposed that the ancestral primate gave birth to singletons. However, primate litter size has not yet been contextualized within a broad phylogenetic assessment of mammalian life history. We performed a comprehensive investigation

Abstract:

Variation in relative brain size among adult mammals is produced by different patterns of brain and body growth across ontogeny. Fetal development plays a central role in generating this diversity, and aspects of prenatal physiology such as maternal relative metabolic rate, altriciality, and placental morphology have been proposed to explain allometric differences in neonates and adults. Primates are also uniquely encephalized across fetal development, but it remains unclear when this pattern emerges during development and whether it is common to all primate radiations.

Primates are unique among mammals in possessing a region of dorsolateral prefrontal cortex with a well-developed internal granular layer. This region is commonly implicated in higher cognitive functions. Despite the histological distinctiveness of primate dorsolateral prefrontal cortex, the work of Rose, Woolsey, and Akert produced a broad consensus among neuroscientists that homologues of primate granular frontal cortex exist in nonprimates and can be recognized by their dense innervation from the mediodorsal thalamic nucleus (MD).
