Reduction of bitter taste receptor gene family in folivorous colobine primates relative to omnivorous cercopithecine primates
Bitter taste perception is important in preventing animals from ingesting potentially toxic compounds. Whole-genome assembly (WGA) data have revealed that bitter taste receptor genes ( TAS2R s) comprise a multigene family with dozens of intact and disrupted genes in primates. However, publicly available WGA data are often incomplete, especially for multigene families. In this study, we employed a targeted capture (TC) approach specifically probin…
Survey report on the current activity of research and education of anthropology by the members of the Anthropological Society of Nippon in 2021
日本の学会や学術研究を取り巻く状況は年々厳しくなっている。そうした状況に適切に対処していくための基礎データを得る目的で,2021年8–9月に,日本人類学会の会員に対してウェブ調査を実施した。(1)会員の職位による研究活動や教育活動の状況,(2)科研費小区分「自然人類学」に対する意識と申請状況,(3)会員の科研費審査への関与状況,(4)自然人類学の下支えのための方策についてのアンケートに対し,会員の23%にあたる123件の有効回答があった。分析の結果,任期の定めのない常勤職では研究・教育活動に割ける時間的余裕が圧倒的に不足している,有期雇用者(ポスドク,テニュアトラック,非常勤講師など)は研究活動に際して専門的な設備やフィールドにアクセスしづらく所属組織からの理解も得づらい,学生では研究に対する意欲を維持しづらい,という回答傾向があった。科研費小区分に「自然人類学」があるほうがよいと答えた回答者の割合は75%だったが,過去5年間以内に研究代表者として「自然人類学」に科研費を申請したことがあ…
Influence of rainfall on sleeping site choice by a group of anubis baboons ( Papio anubis )
For diurnal nonhuman primates, shifting among different sleeping sites may provide multiple benefits such as better protection from predators, reduced risk of parasitic infection, and closer proximity to spatially and temporally heterogeneous food and water. This last benefit may be particularly important in sleeping site selection by primates living in savanna‐woodlands where rainfall is more limited and more seasonally pronounced than in rainfo…
Point of Care Blood Gas and Electrolyte Analysis in Anesthetized Olive Baboons (Papio anubis) in a Field Setting
Capture, immobilization, and Global Positioning System collaring of olive baboons ( Papio anubis ) and vervets ( Chlorocebus pygerythrus )
As the value of Global Positioning System (GPS) technology in addressing primatological questions becomes more obvious, more studies will include capturing and collaring primates, with concomitant increased risk of adverse consequences to primate subjects. Here we detail our experiences in capturing, immobilizing, and placing GPS collars on six olive baboons ( Papio anubis ) in four groups and 12 vervet monkeys ( Chlorocebus pygerythrus ) in five…
The role of sleeping sites in the predator‐prey dynamics of leopards and olive baboons
Predation is widely recognized as an important selective pressure on prey animals such as baboons (Papio spp.), which face high leopard (Panthera pardus) predation risk, particularly at night. Baboons regularly sleep on cliff faces and in trees at night, ostensibly to avoid such predators. Despite retreating to such "refuges," baboons are most often killed by leopards at or near their sleeping sites. Because of the challenges of studying nocturna…
GPS-identified vulnerabilities of savannah-woodland primates to leopard predation and their implications for early hominins
GPS‐identified, low‐level nocturnal activity of vervets ( Chlorocebus pygerythrus ) and olive baboons ( Papio anubis ) in Laikipia, Kenya
OBJECTIVES: Except for owl monkeys (Aotus spp.), all anthropoid primates are considered strictly diurnal. Recent studies leveraging new technologies have shown, however, that some diurnal anthropoids also engage in nocturnal activity. Here we examine the extent to which vervets (Chlorocebus pygerythrus) and olive baboons (Papio anubis) are active at night. MATERIALS AND METHODS: We deployed GPS collars with tri-axial accelerometer data loggers on…
How surviving baboons behaved after leopard predation
Predation has been an evolutionary force in primates, driving changes in their behavior, cognition, and numerous morphological characteristics. There is little evidence regarding the counter-strategies of primates to predation, because previous studies on primates have focused on the animals eaten rather than the animals that survive. I report a case of predation in which an adult male baboon was preyed on by a leopard in the early morning in the…
Ranging behavior of Mahale chimpanzees
Sexually dimorphic preference for altruism in the opposite sex according to recipient
Sexual selection may affect human altruistic behaviour. Evolutionary psychology predicts that human mate preference reflects sexual selection. We investigated sex differences in preference for opposite-sex altruism according to recipient because the reasons for altruistic behaviour differ according to the relationship between actor and recipient. We employed the Self-Report Altruism Scale Distinguished by the Recipient, which was newly developed …
Estrous asynchrony causes low birth rates in wild female chimpanzees
Estrous cycle asynchrony likely functions to elevate individual females' sexual attractiveness during female mate choice. Female chimpanzees show physiological estrus as anogenital swelling. Copulations are concentrated during the period of maximal tumescence, which is called the estrous period. A group of female chimpanzees in Mahale Mountains National Park, Tanzania, was shown to display asynchrony in both maximal tumescence and periovulatory p…
Human prosociality in altruism niche
Possible effects of external and internal factors affecting prosociality in Japanese undergraduates were investigated. We employed social support as an external factor and helping norms, self-consciousness, other-consciousness, self-esteem, and religious attitude as internal factors. Prosociality toward friends/acquaintances was significantly positively correlated with social support from siblings, social support from friends/acquaintances, self-…

Proximity and estrous synchrony in Mahale chimpanzees
Since McClintock [Nature 229:244–255, 1971] first reported menstrual synchrony in women, a number of studies have reported similar phenomena. Many researchers have suggested that one of the proximate factors leading to synchrony is spatial proximity among females (e.g., close friends or roommates). However, most studies on menstrual synchrony have been conducted in limited spaces, and it remains to be determined whether controlled environments, s…
Extraordinarily low bone mineral density in an old female chimpanzee (Pan troglodytes schweinfurthii) from the Mahale Mountains National Park
Demography, female life history, and reproductive profiles among the chimpanzees of Mahale
Demography provides critical data to increase our understanding of the evolution, ecology, and conservation of primate populations. The chimpanzees of the Mahale Mountains National Park, Tanzania, have been studied for more than 34 yr on the basis of individual identification and standardized attendance records. From this long‐term study, we derived the following demographic data: The major cause of death was disease (48%), followed by senescence…

The Four Chimpanzee Skulls Collected in the Mahale Mountains, Tanzania
Morphological and osteological data taken from chimpanzee skeletal materials gathered at chimpanzee research sites are accompanied by life history data (e.g. diet, environment of habitat, sexual activity and social relationship). Unfortunately morphological and osteological studies of chimpanzee skeletal remains from long-term field research projects are rare (Yasui and Takahata, 1983, an infant of P. t. schweinfurthii from Mahale mountains Natio…
Mahale chimpanzees
The social system of chimpanzees (Pan troglodytes schweinfurthii) is characterized by the fission-fusion of social groups. Several studies have reported that females are less gregarious than males. In the current study, adult female gregariousness depended on their reproductive state. Noncycling adult females (pregnant, lactating, or post reproductive) were observed in large bisexual parties less often than cycling adult females. On the other han…
Changes in the activity budget of cycling female chimpanzees
This study is a preliminary report on the time allocated to various activities by female wild chimpanzees (Pan troglodytes schweinfurthii) during their sexual cycle. Cycling females with maximal tumescence (estrous females) tended to spend more time moving than cycling females with quiescent sexual skin (anestrous females). Although there was no statistically significant decrease in any specific activity that corresponded to the increase in time …
