Primates must solve complex spatial problems when foraging, such as finding patchy resources and navigating between different locations. However, the nature of the cognitive representations supporting these types of behaviors is currently unclear. In humans, there has been great debate concerning the relative importance of egocentric representations (which are viewer-dependent) versus allocentric representations (which are based on aspects of the external environment). Comparative studies of nonhuman apes can illuminate which aspects of human spatial cognition are shared with other primates, versus which aspects are unique to our lineage. The current studies therefore examined spatial cognitive development in one of our closest living relatives, bonobos (Pan paniscus) across contexts. The first study assessed how younger bonobos encode locations in a place-response task in which apes first learn that one of two locations is consistently baited with a reward, and then must approach the two locations from
Because of the promiscuous mating behavior of female bonobos, there is a great deal of paternal uncertainty. If a male cannot be sure which offspring are his, he is less likely to invest any time or energy caring for them. It is because of this lack of certainty that the entirety of parental care in bonobos is assumed by the mothers (de Waal 1997). That is not to say that adult males are not attentive to infants in the unit-group, in fact, there is very little aggression directed towards bonobo infants by adult males in the group and infanticide has never been recorded (Kuroda 1989; de Waal 1997). Like all primates, bonobos exhibit a prolonged maturation period that is necessary for behavioral plasticity, strong mother-offspring relationship, and social development (Kuroda 1989). Bonobos, though, when compared to chimpanzees, have a particularly slow rate of development, and it is reported that bonobo mothers are more attentive to their offspring than chimpanzee mothers. In their first years, ...
Their diet consists mainly of plant products including fruit, seeds, sprouts, leaves, flowers, bark, stems, pith, roots, and mushrooms. Though the majority of their diet is fruit (57%), bonobos are also known to consume small mammals, insect larvae, earthworms, honey, eggs, and soil (Kano 1992; Bermejo et al. 1994). Unlike chimpanzees, bonobos do not actively hunt mammalian prey but feed on it opportunistically (White 1996). At one study site, bonobos have been observed washing off their food before eating (Bermejo et al. 1994). Daily activities can be partitioned into six categories: feeding in trees, rest, travel, foraging, nest-building, and group excitement. These daily activities are generally in a cycle of resting (43% of the day), traveling (13%), foraging (20%), and feeding (20%). The remaining time is spent doing other activities. Bonobos forage for principal food items between 25 and 40 m (82 and 131 ft) above the ground. Though most primary food sources are found at this height, they ...
The following editorial comment summarises detailed information given within the LITERATURE REPORTS. Links to the LITERATURE REPORTS are provided at the bottom of this box. WILD POPULATION - IMPORTANCE: The total population is estimated at somewhere between 1,000 and 100,00, and declining.. GENERAL LEGISLATION: Bonobos are listed as Class A in the African Convention on the Conservation of Nature and Natural Resources and listed as Threatened under the U.S. Endangered Species Act.. CITES LISTING: Appendix I. RED-DATA LIST STATUS: Endangered under criteria A4cd (version 3.1). THREATS: Major threats include habitat destruction and hunting - for bushmeat and for parts used in religious rituals. Even in areas where bonobos are not hunted specifically, snares can result in severe injury and loss of digits or limbs. The timber trade, by facilitating assess into the forest, and transport of both people and bushmeat, creates a market for bushmeat; forest workers often are not provided with domestic meat, ...
The ovarian steroids, 17-beta estradiol (E2) and progesterone (P4), are critical for normal uterine function, establishment and maintenance of pregnancy, and mammary gland development. Furthermore, the local effects that are essential for normal ovarian physiology are dependent on the endocrine, paracrine, and autocrine actions of E2, P4, and androgens. In most mammals (including humans and mice), ovarian steroidogenesis occurs according to the two-cell/two-gonadotropin theory. This theory describes how granulosa and theca cells work together to make the ovarian steroids. Theca cells respond to LH signaling by increasing the expression of enzymes necessary for the conversion of cholesterol to androgens, such as androstenedione (A) and testosterone (T). Granulosa cells respond to FSH signaling by increasing the expression of enzymes necessary for the conversion of theca-derived androgens into estrogens (E2 and estrone ...
Allograft rejection is the consequence of the recipients alloimmune response to nonself antigens expressed by donor tissues. After transplantation of organ allografts, there are two pathways of antigen presentation. In the direct pathway, recipient T cells react to intact allogeneic MHC molecules expressed on the surface of donor cells. This pathway would activate host CD4 or CD8 T cells. In contrast, donor MHC molecules (and all other proteins) shed from the graft can be taken up by host APCs and presented to recipient T cells in the context of self-MHC molecules - the indirect pathway. Such presentation activates predominantly CD4 T cells. A direct cytotoxic T-cell attack on graft cells can be made only by T cells that recognize the graft MHC molecules directly. Nontheless, T cells with indirect allospecificity can contribute to graft rejection by activating macrophages, which cause tissue injury and fibrosis, and are also likely to be important in the development of an alloantibody response ...
Acts as a tumor suppressor in many tumor types; induces growth arrest or apoptosis depending on the physiological circumstances and cell type. Involved in cell cycle regulation as a trans-activator that acts to negatively regulate cell division by controlling a set of genes required for this process. One of the activated genes is an inhibitor of cyclin-dependent kinases. Apoptosis induction seems to be mediated either by stimulation of BAX and FAS antigen expression, or by repression of Bcl-2 expression.
Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) are the closest living relatives of humans, but the two species show distinct behavioral and physiological differences, particularly regarding female reproduction. Despite their recent rapid decline, the demographic histories of the two species have been different during the past 1-2 Myr, likely having an impact on their genomic diversity. Here, we analyze the inferred functional consequences of genetic variation across 69 individuals, making use of the most complete data set of genomes in the Pan clade to date. We test to which extent the demographic history influences the efficacy of purifying selection in these species. We find that small historical effective population sizes (Ne) correlate not only with low levels of genetic diversity but also with a larger number of deleterious alleles in homozygosity and an increased proportion of deleterious changes at low frequencies. To investigate the putative genetic basis for phenotypic ...
Observations of chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) provide valuable comparative data for understanding the significance of conspecific killing. Two kinds of hypothesis have been proposed. Lethal violence is sometimes concluded to be the result of adaptive strategies, such that killers ultimately gain fitness benefits by increasing their access to resources such as food or mates1, 2, 3, 4, 5. Alternatively, it could be a non-adaptive result of human impacts, such as habitat change or food provisioning6, 7, 8, 9. To discriminate between these hypotheses we compiled information from 18 chimpanzee communities and 4 bonobo communities studied over five decades. Our data include 152 killings (n = 58 observed, 41 inferred, and 53 suspected killings) by chimpanzees in 15 communities and one suspected killing by bonobos. We found that males were the most frequent attackers (92% of participants) and victims (73%); most killings (66%) involved intercommunity attacks; and attackers ...
The Wolfgang Köhler Primate Research Center (Pongoland) is a project of the Max Planck Institute for Evolutionary Anthropology. It is operated in collaboration with the Leipzig Zoo. Research focuses on the behavior and cognition of the four species of great ape: chimpanzees (Pan troglodytes), gorillas (Gorilla gorilla), Organgutans (Pongo pygmaeus), and bonobos (Pan paniscus). There is a special focus on the ontogeny of chimpanzee cognition. Researchers and students from the University of Leipzig, and other universities around the world, conduct their research projects at the center guided by the personnel of the Center ...
UPDATE: I emailed one of the researchers and I got this response: Hello, you are of course absolutely right. Bonobos are equally distant to people from Africa, Europe or anywhere else in the world. The X/A ratio measures something completely different: It compares individuals from a certain group (bonobos, chimpanzees, or human populations) and compares…
In 1999, neuroscientist Prof. John Allman and colleagues at the California Institute of Technology first published a report[12] on spindle neurons found in the anterior cingulate cortex (ACC) of hominids, but not in any other species. Neuronal volumes of ACC spindle neurons were larger in humans and bonobos (Pan paniscus) than the spindle neurons of the common chimpanzee, gorilla, and orangutan. Allman and his colleagues[13] have delved beyond the level of brain infrastructure to investigate how spindle neurons function at the superstructural level, focusing on their role as «air traffic controllers for emotions ... at the heart of the human social emotion circuitry, including a moral sense»[14]. Allmans team proposes that spindle neurons help channel neural signals from deep within the cortex to relatively distant parts of the brain. Specifically, Allmans team[15] found signals from the ACC are received in Brodmanns area 10, in the frontal polar cortex, where regulation of cognitive ...

Camillo is the highest ranking male bonobo of the study group. He is often seen in his mothers company. Image: Caroline Deimel, Lui Kotale Bonobo Project. Variation in male mating success is often related to rank differences. Males who are unable to monopolize estrous females alone may engage in coalitions with other group members to chase higher ranking males off these females and to thus enhance their own mating success.. Studies on chimpanzees and dolphins suggest that coalitions are independent of kinship. Information from species in which females remain in their natal group, on the other hand, shows the importance of kin support, especially from mothers, on the reproductive success of their daughters. Therefore, one might expect a similar effect on sons in species in which males remain in their natal group like bonobos. "With our study we wanted to find out whether in bonobos the mating success of the sons was indeed influenced by the support they received from their mothers", says Martin ...
The bonobo, along with the chimpanzee, is one of our two closest living relatives. Their relatively narrow geographic range (south of the Congo River in the Democratic Republic of Congo) combined with the history of political instability in the region, has made their scientific study extremely difficult. In contrast, there are dozens of wild and captive sites where research has been conducted for decades with chimpanzees.
April Flowers for redOrbit.com - Your Universe Online. In 2002 a fossil specimen of an ape skeleton was unearthed in Spain. The researchers who discovered the remains assigned it a new genus and species, Pierolapithecus catalaunicus, estimating that the ape lived about 11.9 million years ago. The researchers argued that the ape could be the last common ancestor of modern great apes, which include chimpanzees, orangutans, bonobos, gorillas and humans.. Now a new study led by a University of Missouri integrative anatomy expert has revealed that the shape of the ape´s pelvis indicates that it lived near the beginning of the great ape evolution after the lesser apes started to independently develop but before the great ape species began to diversify.. The international team was led by Ashley Hammond, a Life Sciences Fellow in the MU Department of Pathology and Anatomical Sciences, and included members from the Autonomous University of Barcelona, the University of Turin and Stony Brook University. ...
THE GREAT APE NEUROSCIENCE PROJECT PROGRESS REPORT - FEBRUARY 2011 Introduction. As our closest living relatives, great apes share similarities with humans in terms of cognition, emotion, sociality, and susceptibility to some diseases of aging. Yet despite these striking similarities, important differences exist that set humans apart with regard to brain structure and function. The overarching goal of the Great Ape Neuroscience Project is to investigate the neurobiological basis of variation
Malaria parasites, although widespread among wild chimpanzees and gorillas, have not been detected in bonobos, a chimp cousin.

An animal sanctuary is a facility where animals are brought to live and be protected for the rest of their lives.[1] Unlike animal shelters, sanctuaries do not seek to place animals with individuals or groups, instead maintaining each animal until his or her natural death. In some cases, an establishment may have characteristics of both a sanctuary and a shelter; for instance, some animals may be in residence temporarily until a good home is found and others may be permanent residents. The mission of sanctuaries is generally to be safe havens, where the animals receive the best care that the sanctuaries can provide. Animals are not bought, sold, or traded, nor are they used for animal testing. The resident animals are given the opportunity to behave as naturally as possible in a protective environment.[1]. What distinguishes a sanctuary from other institutions is the philosophy that the residents come first. In a sanctuary, every action is scrutinized for any trace of human benefit at the ...

Human females have concealed ovulation or hidden estrus. Most female animals show distinctive signs when they are "in heat". These include swelling and redness of the genitalia in baboons and bonobos, pheromone release in the feline family, etc. By comparison, human females have few external signs of fertility. It is difficult to tell, by means of external signs only, whether or not a woman is ovulating at the time. Humans are the only mammal to lack obvious, visible manifestations of ovulation, although some argue that the extended estrus period of the bonobo (reproductive-age females are in heat for 75% of their menstrual cycle)[1] has a similar effect to the lack of a "heat" in human females.[2] While women can be taught to recognize their own ovulation (fertility awareness), whether men can detect ovulation in women is highly debated. At least one recent study has argued that men are more likely to initiate sex with fertile women[3], while another has found male-initiated sex to occur at a ...

This only serves to further illustrate what i just said, a complete misunderstanding of evolution. The fossil record shows that we humans shared a common ancestor with some of the primates; the great apes. DNA supports this, with our closest extant relatives being Chimpanzees and Bonobos, Orang-Utans and Gorillas. Transitional forms support this. Just even looking at evidence available today supports this; our skeletons, our shared teeth formation, our brain size in relation to our bodies, our skulls, opposable thumbs. the fact we also have an appendix, though unused now in humans, that it is still used by our closest relatives because of their mostly herbivorous diets. Our chromosome (the organised structure of DNA and protein in all cells) sequence of 23 pairs, rather than 24 pairs as with the other primates, and the fact that humans show a fused second chromosome, which shows a link between us and the other great apes, since it is suggestive that we formerly had, also, 24 pairs. We retain the ...

Amos was one of the handsomest males I have known, except perhaps on the day he stuffed two entire apples in his mouth, which taught me again that chimpanzees can do things we cant. He had large eyes in a friendly, symmetrical face, a full, shiny coat of black hair, and well-defined muscles on his arms and legs. He was never overly aggressive, as some males can be, yet he was supremely self-confident during his heyday. Amos was beloved. Some of us cried at the time when he died, and his fellow apes were eerily silent for days. Their appetites took a hit.. At the time, we didnt know what his problem was, but we learned postmortem that in addition to a hugely enlarged liver that took up most of his abdomen, he had several cancerous growths. He had lost 15 percent of his weight from a year before, but even though his condition must have been building for years, he had acted normally until his body just couldnt hold out any longer. Amos must have felt miserable for months, but any sign of ...

Wife checking husbands head for lice in hunting camp.. It was also Sarah who solved the problem of bad hunting luck. Neither Tshukizas nor Kenges net caught anything the first few days out at Kiokiokio. The women were the first to be blamed. Perhaps they had accompanied the hunt while menstruating. This was less than likely as Safenia had stayed in camp with Sarah and Fatuma, Tshukizas wife, was pregnant. In any case, Safenia and Fatuma, without much of a show of contrition, cut their tongues and spit blood on the nets. Safenia called out the names of all potential game animals. Tshukiza hung the nets under which he burned little packets of dawa, leaves thought capable of curing the problem. Nevertheless, that day their nets came back empty again.. The next morning Safenia took up a wooden bugali spoon and started beating Kenges net. "What is this? You dont kill animals? Where is the sundura, mboloko, nge, kuva…? Sarah thought it was great fun. She took the wooden paddle and went at it ...

The inward sanctuary is my sanctuary. It is the place where I keep my trust with all my meanings and my values. It is the quiet place where the ultimate issues of my life are determined. What I know of myself, my meaning; what I know of God, His meaning; all this, and much more, is made clear in my secret place. It seems strangely incongruous, often, to bring into my secret place the rasping, gritty noises of my outer life. Again, this may be for me merely an alibi.
