Loss of olfactory receptor genes coincides with the acquisition of full trichromatic vision in primates. (1/67)

Olfactory receptor (OR) genes constitute the molecular basis for the sense of smell and are encoded by the largest gene family in mammalian genomes. Previous studies suggested that the proportion of pseudogenes in the OR gene family is significantly larger in humans than in other apes and significantly larger in apes than in the mouse. To investigate the process of degeneration of the olfactory repertoire in primates, we estimated the proportion of OR pseudogenes in 19 primate species by surveying randomly chosen subsets of 100 OR genes from each species. We find that apes, Old World monkeys and one New World monkey, the howler monkey, have a significantly higher proportion of OR pseudogenes than do other New World monkeys or the lemur (a prosimian). Strikingly, the howler monkey is also the only New World monkey to possess full trichromatic vision, along with Old World monkeys and apes. Our findings suggest that the deterioration of the olfactory repertoire occurred concomitant with the acquisition of full trichromatic color vision in primates.  (+info)

Tracking Alu evolution in New World primates. (2/67)

BACKGROUND: Alu elements are Short INterspersed Elements (SINEs) in primate genomes that have proven useful as markers for studying genome evolution, population biology and phylogenetics. Most of these applications, however, have been limited to humans and their nearest relatives, chimpanzees. In an effort to expand our understanding of Alu sequence evolution and to increase the applicability of these markers to non-human primate biology, we have analyzed available Alu sequences for loci specific to platyrrhine (New World) primates. RESULTS: Branching patterns along an Alu sequence phylogeny indicate three major classes of platyrrhine-specific Alu sequences. Sequence comparisons further reveal at least three New World monkey-specific subfamilies; AluTa7, AluTa10, and AluTa15. Two of these subfamilies appear to be derived from a gene conversion event that has produced a recently active fusion of AluSc- and AluSp-type elements. This is a novel mode of origin for new Alu subfamilies. CONCLUSION: The use of Alu elements as genetic markers in studies of genome evolution, phylogenetics, and population biology has been very productive when applied to humans. The characterization of these three new Alu subfamilies not only increases our understanding of Alu sequence evolution in primates, but also opens the door to the application of these genetic markers outside the hominid lineage.  (+info)

Independent origin of the growth hormone gene family in New World monkeys and Old World monkeys/hominoids. (3/67)

The growth hormone (GH) gene family represents an erratic and complex evolutionary pattern, involving many evolutionary events, such as multiple gene duplications, positive selection, the birth-and-death process and gene conversions. In the present study, we cloned and sequenced GH-like genes from three species of New World monkeys (NWM). Phylogenetic analysis strongly suggest monophyly for NWM GH-like genes with respect to those of Old World monkeys (OWM) and hominoids, indicating that independent gene duplications have occurred in NWM GH-like genes. There are three main clusters of genes in putatively functional NWM GH-like genes, according to our gene tree. Comparison of the ratios of nonsynonymous and synonymous substitutions revealed that these three clusters of genes evolved under different kinds of selective pressures. Detailed analysis of the evolution of pseudogenes showed that the evolutionary pattern of this gene family in platyrrhines is in agreement with the so-called birth-and-death process.  (+info)

Fatal poxvirus outbreak in a colony of New World monkeys. (4/67)

An epizootic infection was observed in a colony of 80 New World monkeys consisting of various species including a group of marmosets and Saguinus species. During the summer and autumn of 2002, 30 animals died of unknown diseases. Six animals were sent to the German Primate Center for investigation of the cause of death. A complete pathologic and histologic investigation was carried out. The animals exhibited erosive-ulcerative lesions of the oral mucous membranes. Advanced stages of the disease were characterised by hemorrhagic lesions on the skin distributed randomly over the body, but principally on the face, scrotal region, soles, and palms. Electron microscopy revealed virus particles with orthopox-like morphology within intracytoplasmic inclusions in epithelial cells. The DNA samples from various tissues were analyzed by use of a set of orthopox virus-specific, real-time polymerase chain reaction assays. Amplification products were sequenced to define the virus more precisely. Sequencing confirmed the presence of an orthopox virus. Sequence data indicated that all six animals were infected with the same virus. Propagation of the virus on Vero cells resulted in a rapidly progressive cytopathogenic effect. Preliminary phylogenetic analyses of two genes revealed closest homology to cowpox viruses. The origin of this poxvirus outbreak remains unexplained, and the strain and genus of the virus need to be determined in detail.  (+info)

An anthropoid-specific segmental duplication on human chromosome 1q22. (5/67)

Segmental duplications (SDs) play a key role in genome evolution by providing material for gene diversification and creation of variant or novel functions. They also mediate recombinations, resulting in microdeletions, which have occasionally been associated with human genetic diseases. Here, we present a detailed analysis of a large genomic region (about 240 kb), located on human chromosome 1q22, that contains a tandem SD, SD1q22. This duplication occurred about 37 million years ago in a lineage leading to anthropoid primates, after their separation from prosimians but before the Old and New World monkey split. We reconstructed the hypothetical unduplicated ancestral locus and compared it with the extant SD1q22 region. Our data demonstrate that, as a consequence of the duplication, new anthropoid-specific genetic material has evolved in the resulting paralogous segments. We describe the emergence of two new genes, whose new functions could contribute to the speciation of anthropoid primates. Moreover, we provide detailed information regarding structure and evolution of the SD1q22 region that is a prerequisite for future studies of its anthropoid-specific functions and possible linkage to human genetic disorders.  (+info)

Distribution patterns of Neotropical primates (Platyrrhini) based on Parsimony Analysis of Endemicity. (6/67)

The Parsimony Analysis of Endemicity (PAE) is a method of historical biogeography that is used for detecting and connecting areas of endemism. Based on data on the distribution of Neotropical primates, we constructed matrices using quadrats, interfluvial regions and pre-determinated areas of endemism described for avians as Operative Geographic Units (OGUs). We codified the absence of a species from an OGU as 0 (zero) and its presence as 1 (one). A hypothetical area with a complete absence of primate species was used as outgroup to root the trees. All three analyses resulted in similar groupings of areas of endemism, which match the distribution of biomes in the Neotropical region. One area includes Central America and the extreme Northwest of South America, other the Amazon basin, and another the Atlantic Forest, Caatinga, Cerrado and Chaco.  (+info)

Fast and non-invasive PCR sexing of primates: apes, Old World monkeys, New World monkeys and Strepsirrhines. (7/67)

BACKGROUND: One of the key tools for determining the social structure of wild and endangered primates is the ability to sex DNA from small amounts of non-invasive samples that are likely to include highly degraded DNA. Traditional markers for molecular sex determination of primates are developed on the basis of the human sequence and are often non-functional in distantly related primate species. Hence, it is highly desirable to develop markers that simultaneously detect Y- and X-chromosome specific sequences and also work across many species. RESULTS: A novel method for sex identification in primates is described using a triple primer PCR reaction and agarose gel electrophoresis of the sex-chromosomal isoforms of the ubiquitously transcribed tetratricopeptide repeat protein gene (UTX/UTY). By comparing genomic data from several mammals we identified the UTX/UTY locus as the best candidate for a universal primate sexing marker. Using data from several species we identified a XY-conserved region, a Y conserved region and an X conserved region. This enabled the design of a triple primer PCR setup that amplifies X and Y products of different length in a single PCR reaction. CONCLUSION: This simple PCR amplification of X and Y fragments is useful for sexing DNA samples from all species of primates. Furthermore, since the amplified fragments are very short the method can be applied to fragmented DNA extracted from non-invasive samples.  (+info)

Isolation of an active Lv1 gene from cattle indicates that tripartite motif protein-mediated innate immunity to retroviral infection is widespread among mammals. (8/67)

Lv1/TRIM5alpha (tripartite motif 5alpha) has recently emerged as an important factor influencing species-specific permissivity to retroviral infection in a range of primates, including humans. Old World monkey TRIM5alpha blocks human immunodeficiency virus type 1 (HIV-1) infectivity, and the human and New World monkey TRIM5alpha proteins are inactive against HIV-1 but active against divergent murine (N-tropic murine leukemia virus [MLV-N]) and simian (simian immunodeficiency virus from rhesus macaque [SIVmac]) retroviruses, respectively. Here we demonstrate antiviral activity of the first nonprimate TRIM protein, from cattle, active against divergent retroviruses, including HIV-1. The number of closely related human TRIM sequences makes assignment of the bovine sequence as a TRIM5alpha ortholog uncertain, and we therefore refer to it as bovine Lv1. Bovine Lv1 is closely related to primate TRIM5alpha proteins in the N-terminal RING and B-box 2 domains but significantly less homologous in the C-terminal B30.2 domain, particularly in the region shown to influence antiviral specificity. Intriguingly, some viruses restricted by bovine Lv1, including HIV-1 and MLV-N, are unable to synthesize viral DNA by reverse transcription, whereas restricted HIV-2 makes normal amounts of DNA. The data support the conclusion that TRIM protein-mediated restriction of retroviral infection is a more common attribute of mammals than previously appreciated.  (+info)

New World monkeys are small to mid-sized primates, ranging from the pygmy marmoset (the worlds smallest monkey), at 14 to 16 cm (5.5 to 6.5 in) and a weight of 120 to 190 g (4.2 to 6.7 oz), to the southern muriqui, at 55 to 70 cm (22 to 28 in) and a weight of 12 to 15 kg (26 to 33 lb).

The organization, evolution and function of eukaryotic centromeres represent a deficiency in our understanding of genome biology. The discovery of human clinical neocentromeres and ENCs has further complicated, on one hand, our understanding of the centromere. On the other hand, neocentromeres and ENCs have allowed an initial dissection of centromere complexity. They have made evident, for instance, its epigenetic nature. The ENC analysis we have accomplished in the present study has contributed to the identification of factors that, very likely, play a crucial role in ENC progression and fixation in the population. We have provided strong evidence that the pericentromeric duplication activity is an intrinsic property of ENCs. This conclusion was mainly supported by FISH experiments using species-specific BAC clones that detected SDs around the centromere in almost all studied ENCs. A deep restructuring was particularly evident in MMU17 (human 13) and MMU2 (human 3). The latter ENC showed a ...

Why biodiversity is not uniformly distributed on the Earth is a major research question of biogeography. One of the most striking patterns of disparity in species distribution are the biodiversity hotspots, which generally do not fit with the distribution of relevant components of the Neotropical biota. In this study, we assess the proximal causes of the species-richness pattern of one of the most conspicuous groups of Neotropical mammals, the New World monkeys the Platyrrhini. We test two complementary hypotheses : (1) there is a historical source-sink dynamic (addressed using macroevolutionary and macroecological approaches) ; (2) the large number of species in the Amazon basin is due to the constraints imposed by environmental variables occurring outside this area.(...).

In many platyrrhine types, by comparison, just a percentage of females are trichromats (regular or anomalous). The staying females and all men are dichromats because there are just two code genetics for opsins, one in the X-chromosome and another in the chromosome 7. In men, with just one homozygous and X-chromosome females, the total result is normally dichromacy, while in heterozygous females gene ...

A monkey is a primate, either an Old World monkey or a New World monkey. There are about 260 known living species of monkey. Many are arboreal, although there are species that live primarily on the ground, such as baboons. Monkeys are generally considered to be intelligent. Unlike apes, monkeys usually have tails. Tailless monkeys may be called "apes", incorrectly according to modern usage; thus the tailless Barbary macaque is called the "Barbary ape". ...
Oligopithecidae is an extinct primate family from the late Eocene of Egypt (about 37 million years ago). Its members were probably insectivorous due to their simple molars and cusp arrangement.

Viral DNA or RNA that benignly settles itself into a vector or inside human DNA itself turns into a sleeping gene, enjoying the protection of a longer-lived cell. That means it doesnt aggravate the immune system to destroy it. That could easily account for the tolerance of humans and new world monkeys to all the viral DNA that has accumulated all this time. Social patterns can only account for so much, since many viruses travel through touch and aerosol to infect others. Blood is not the only means of transmission.. Evolution in small organisms proceeds at a much more rapid pace than in organisms even as small as a shrimp. This is because generations recur in very short periods of time: one virus invades another cell, produces progeny, they break out of the cell and do the same-and there are many cells they can invade.

That means it doesnt aggravate the immune system to destroy it. That could easily account for the tolerance of humans and new world monkeys to all the viral DNA that has accumulated all this time. Social patterns can only account for so much, since many viruses travel through touch and aerosol to infect others. Blood is not the only means of transmission.. Evolution in small organisms proceeds at a much more rapid pace than in organisms even as small as a shrimp. This is because generations recur in very short periods of time: one virus invades another cell, produces progeny, they break out of the cell and do the same-and there are many cells they can invade. The more generations there are-and you get many in one bout of illness-the more chance there is that a quiescent mutation can occur. This mutated virus can invade a cell and just ...
H.G. Wells advised in his 1940 work The New World Order that "... when the struggle seems to be drifting definitely towards a world social democracy, there may still be very great delays and disappointments before it becomes an efficient and beneficent world system. Countless people ... will hate the new world order ... and will die protesting against it. When we attempt to evaluate its promise, we [must] bear in mind the distress of a generation or so of malcontents, many of them quite gallant and graceful-looking people."[34] He called for the effort to organize prominent intellectuals behind the idea of establishing a World Government, in which his writings would be expected to have an instrumental role, in the "Open Conspiracy" (a benevolent one) in his book published under that name in 1928.[35] ...

The brown howler (Alouatta guariba) is a New World monkey that is native to the far northeastern portions of Argentina, and Brazil. It is also commonly known as the brown howling monkey. Although its name implies that it is brown, it can vary in color with some individuals appearing to be redder in color or even black. It typically lives in small groups that contain up to eleven individuals. It holds two subspecies, one of which is critically endangered. The brown howler as a species appears on the IUCN Red List with a conservation status of "Least Concern".. Image Caption: Brown Howler Monkey, Alouatta guariba clamitans Horto Florestal de São Paulo.

The vomeronasal organ (VNO) detects pheromones in many vertebrate species but is likely to be vestigial in humans. TRPC2(TRP2), a gene that is essential for VNO function in the mouse, is a pseudogene in humans. Because TRPC2 is expressed only in the VNO, the loss of selective pressure on this gene can serve as a molecular marker for the time at which the VNO became vestigial. By analyzing sequence data from the TRPC2 gene of 15 extant primate species, we provide evidence that the VNO was most likely functional in the common ancestor of New World monkeys and Old World monkeys and apes, but then became vestigial in the common ancestor of Old World monkeys and apes. We propose that, at this point in evolution, other modalities, notably the development of color vision, may have largely replaced signaling by pheromones ...

Light is a very interesting phenomenon. Different animals use it in different ways. Colobus monkeys tend to target young reddish not green leaves. Plant species tend to have young leaves that are red and are more nutritious. They are simply taking advantage of their sense of full color vision. This is the ability to distinguish certain shades of colors. Therefore this ability helps them with their survival. Non-primate animals lack full color vision. More specifically apes and Old World monkeys have trichromatic vision. This means they see across the visible spectrum from blue to green to red. Most animals are dichromatic which means they only see blue and yellow. Therefore in the case of the red leaves or the green leaves, dichromatic animals do not have the ability to see the red leaves.. This ability of animals to see light and distinguish color is a physiological response of the eye to light. The human eye usually has only three types of color receptors and each one is stimulated by light of ...
Mico marcai é uma espécie de primata do Novo Mundo endêmico da Amazônia brasileira. É uma das espécies de primata menos conhecida, e até 2008 não havia sido observada em estado selvagem. Foi descrito originalmente como uma subespécie de Mico argentatus (Callithrix argentata marcai). Ocorre entre os rios Aripuanã e Manicoré, limitado ao norte pelo rio Madeira, ocorrendo junto com Callibella humilis. A espécie Mico manicorensis tem sido aceita como sinônimo de M. marcai, dado que não existem diferenças morfológicas significativas entre as duas espécies e nem barreiras geográficas separando as suas ocorrências.

The complement component C4 genes of Old World primates exhibit a long/short dichotomous size variation, except that chimpanzee and gorilla only contain short C4 genes. In human it has been shown that the long C4 gene is attributed to the integration of an endogenous retrovirus, HERV-K(C4), into intron 9. This 6.36 kilobase retroviral element is absent in short C4 genes. Here it is shown that the homologous endogenous retrovirus, ERV-K(C4), is present precisely at the same position in the long C4 gene of orangutan and African green monkey. Determination of the short C4 gene intron 9 sequences from human, three apes, two Old World monkeys, and a New World monkey allowed the establishment of consistent phylogenetic trees for primates, which favors a chimpanzee-gorilla clade. The 5 long terminal repeats (LTR) and 3 LTR of ERV-K(C4) in long C4 genes of human, orangutan, and African green monkey have similar sequence divergence values of 9.1%-10.5%. These values are more than five-fold higher than ...

Brand New Book. This book provides a novel focus on adaptive explanations for cranial and postcranial features and functional complexes, socioecological systems, life history patterns, etc. in early primates. It further offers a detailed rendering of the phylogenetic affinities of such basal taxa to later primate clades as well as to other early/recent mammalian orders. In addition to the strictly paleontological or systemic questions regarding Primate Origins, the editors concentrate on the adaptive significance of primate characteristics. Thus, the book provides the broadest possible perspective on early primate phylogeny and the adaptive uniqueness of the Order Primates.

Why do humans see in all three colors? There isnt a certain answer. Multiple hypotheses have been proposed. Peter Lucas, my former professor, believes our ability to see reds was advantageous in helping our ancestors see young red leaves, which are especially nutritious, against a background that is mostly made up of shades of green (Lucas et al., 1998). Our closest living relatives, chimpanzees and gorillas, consume a diet mainly composed of leaves. Or perhaps we see reds because red fruit is often ripe and therefore we can distinguish ripe fruit against a green background (Allen, 1879; Mollon, 1989; Fleagle, 1999). Yet, if this were the complete answer, wouldnt we expect New World Monkeys, who consume fruit, to see red wavelengths? Another hypothesis suggests that our ability to see shades of red occurred so that male Old World Monkeys could more easily discern the sexual swellings of females that were in estrous (Liman and Innan, 2003 ...

Researchers at the University of Washington - Seattle examined a small section of chromosome 2 in humans, apes and old world monkeys. What they found was that old world monkeys did not have a series of duplications found in apes and humans - implying the duplications occurred after the last common ancestor of old world monkeys, apes and humans (approximately 10-20 mya). An interesting finding is that the gene duplications occurred in a very short timespan. How does the article characterize the research ( Did Humans Evolve in Fits and Starts?)?. ...
Aha! I must make it clear that I have been using the term monkey as a direct match for the term Simiiformes (which includes the Old and New World monkeys, the lesser apes and the great apes) in the discussion above, but is that valid?. Obviously I argue that it is, since Ive been using it - the question should be why wouldnt it be valid? The only logically robust answer (that I can think of) is that it wouldnt be valid if people dont commonly use the two terms to refer to the same things. So do people use the term monkey to refer to the apes?. The simple fact is that this whole discussion has been raised because Graham Smith published an article in which he refer to apes as monkeys, which demonstrates that monkey is indeed used as a generic term to refer to apes.. Another example is Terry Pratchetts Discworld, where the Librarian (who happens to be an Orang-utan) dislikes being referred to as a monkey, which happens regularly - it may be fiction, but it seems reasonable to suggest that it ...
Hi, folks, Im trolling this through sci.med in the hopes of picking up some M.D. readers who have hematology experiemce but who dont ordinar- ily read the bionet newsgroups. Similarly for bionet.immunology. How- ever, I have set the followups back to bionet.cellbiol, which I think is the most appropriate newsgroup for this rather technical discussion. Ive run into an interesting problem. I am working with an an- tibody to the class I MHC molecule. I am studying class I MHC in a species of New World Monkey; some individuals react to this antibody, and some of them do not. The antibody recognizes an epitope that spans across the class I heavy chain and beta-2 microglobulin. I have identi- fied an amino acid polymorphism in beta-2m that is responsible for the antibody reactivity. You may recall that class I heavy chains are membrane-anchored molecules, but beta-2m is not. So class I heavy chains can lose their endogenous beta-2m in cell culture, and pick up the beta-2m from the cul- ture medium. ...

The Nyaya school classified inference into several types: inference for oneself (Svarthanumana), inference for others (Parathanumana), Purvavat (inferring an unperceived effect from a perceived cause), Sheshavat (inferring an unperceived cause from a perceived effect), and Samanyatodrishta (when inference is not based on causation but on uniformity of co-existence). A detailed analysis of error is also given, explaining when anumana could be false. The Nyaya theory of error is similar to that of Kumarilas Viparita-khyati (see Mimamsa). The Nyayayikas also believe that error is due to a wrong synthesis of the presented and the represented objects. The represented object is confused with the presented one. The word anyatha means elsewise and elsewhere and both these meanings are brought out in error. The presented object is perceived elsewise and the represented object exists elsewhere. They further maintain that knowledge is not intrinsically valid but becomes so on account of extraneous ...

Can you imagine someone hearing you holler from three kilometer away? Howler Monkeys have the loudest sound of any land animal, and it can be heard for three kilometers because of a bone its throat that acts like an amplifier. The noise you hear really does have a purpose. It saves the monkey energy. The male Howler Monkeys set up a howl that other male Howler Monkeys hear and respond to. In this manner they can locate one another, and avoid the territories of other Howler Monkeys. This decreases the amount of energy they have to spend fighting for territorial rights.. South America hosts the Howler Monkey. South Brazil, northern Argentina, Paraguay and Bolivia are a few countries in which this monkey lives. They enjoy the rainforests, secondary forests, mangroves and cloud forests that these places offer.. The yellow-brown female Howler Monkeys and the, often black male Howler Monkeys are well adapted to their lives high in the trees. Their greatest asset is a thick power full tail that can ...

... s are New World monkeys of the family Atelidae, subfamily Atelinae. Found in tropical forests from southern Mexico to Brazil, spider monkeys belong to the genus Ateles; the closely related woolly spider monkeys are in the genus Brachyteles.. As they require large tracts of undisturbed forest and specialize on ripe fruits, spider monkeys may be considered an indicator species. The monkeys are threatened by habitat destruction through continued growth in South American agriculture. Disproportionately long, spindly limbs inspired the spider monkeys common name. Their deftly prehensile tails have highly flexible hairless tips.. Spider monkeys have hook-like, narrow and thumbless hands; the fingers are elongate and recurved. The hair is coarse, ranging in color from a ruddy gold to brown and black; the hands and feet are usually black. Heads are small with hairless faces. An unusually long labia in females may be mistaken for a penis; it is used to attract the males. A female will ...

The genome of the common marmoset (Callithrix jacchus) represents the first sequenced and analyzed New World monkey (NWM, platyrrhine) genome. C. jacchus is also a common animal model for studying human disease, including neuroscience and infectious diseases. In its draft genome assembly [calJac3.2], we identified a novel mobile element, dubbed Platy-1.. Based on our comparative analyses, we determined that Platy-1 elements are unique to NWMs. A full-length Platy-1 element is just over 100 bp in length and does not appear to contain coding sequence. Platy-1 elements exhibit facets such as termination in an Adenosine tail of varying length, target site duplications, and an endonuclease cleavage site characteristic of non-LTR retrotransposons. The combination of these features strongly suggests that Platy-1 elements are inserted in the genome by the enzymatic machinery of L1 through a mechanism called target-primed reverse transcription. Based on our whole genome analysis, we determine that the C. ...

Modern platyrrhines live in Central and South America but its not entirely clear how their common ancestor got there. At the time, around 25 million years ago, the Panama land bridge that connected North and South American hadnt formed, and the Atlantic Ocean was narrower. Its possible that this ancient monkey rafted across from Africa. No matter how it got there, what happened next is clearer thanks to Perelmans study.. After they reached South America, the platyrrhines diverged into three major families. The first to branch off were the pithecids, including the titis, the bald-faced uakaris (top left), the bearded sakis. Next came the atelids with their long, prehensile tails, including the howler (bottom right), spider and woolly monkeys.. Finally, the cebids. This group includes several species that have previously been classified in separate families; Perelman has decided to united them in one. They diverged in quick succession - first, the capuchins and squirrel monkeys (bottom left), ...

Aim In 1833, C.L. Gloger observed that bird populations living in warm and wet habitats were darker than those found in dry, cool areas. However, this hypothesis has seldom been evaluated, particularly for mammals. Here, we test Glogers rule using a dataset consisting of more than 100 primate species representing all major primate clades.. Location Africa, Madagascar, Asia and the Neotropics.. Methods We used museum skins, digital photography, and colour correction software to quantify the brightness of the dorsal and ventral pelage surface of each species. We utilized the mean actual evapotranspiration (AET) within the geographic range of each species as a proxy for habitat conditions and accounted for additional variables that may influence coloration. To analyse the data, we used a generalized linear model that simultaneously accounts for the effects of phylogenetic and spatial autocorrelation.. Results We found that increasing levels of AET were significantly related to increasing pelage ...

Northfield, Minn.-- Julie Neiworth, Carleton College professor of psychology and director of neuroscience, has been awarded an Academic Research Enhancement Award (AREA) grant of $344,204 from the National Institutes of Health (NIH) for her research "Revisiting Challenged Findings to Determine Social and Cognitive Abilities in Tamarins.". Neiworth will test tamarins, a new world monkey species, on several aspects of cognition contested in psychology due to the retraction or correction of work from former Harvard psychologist Marc Hauser. The topics include recognition of human speech, theory of mind, and social learning. Five undergraduate collaborators/student researchers assisted with the work this summer; ten students will continue that work this fall.. The research involves Carletons colony of 13 tamarins that are all adults and have been reared in social groups. Neiworth notes tamarins are prized in comparative research when considering primates and the evolution of mind since they ...

Bringing rice to the New World created a circle of events that the New World is still dealing with today. With rice came Africans who cared for the rice. With Africans came malaria, which many slaves were immune to but white farmers were not. This was one of many factors that helped to sustain and keep the slave trade going. The slave trade and slavery are often blamed as a factor for racism that still exists today in America. What if rice had not been brought to the New World? Would the slave trade have lasted so long? With fewer breeding grounds, would mosquitoes not have flourished and spread malaria in the New World? One can only imagine how history might be different if rice had never been brought to the New World. Rice has had lasting effects on the New World and has changed the history of the New World.

Mantled howler monkey (Alouatta palliata), Costa Rica. The mantled howler (Alouatta palliata), or golden-mantled howling monkey, is a species of howler monkey, a type of New World monkey, from Central and South America. It is one of the monkey species most often seen and heard in the wild in Central America. It takes its mantled name from the long guard hairs on its sides. The mantled howler is one of the largest Central American monkeys. Image by Andres Morya
New world Primates are represented by the suborder Platyrrhini. This includes the families Callitrichidae (marmosets and tamarins), Callimiconidae (Goeldis monkey) and Cebidae (cebids) with a total of 55 species according to Honacki et al. (285) and Hershkovitz (277). Some authors (69, 393) recognize a larger number of callitrichids. The primates are the best studied and best known group of neotropical mammals, which is why an exhaustive review of the relevant literature would exceed the purpose of this book. A number of primates are used for food or captured alive or bred for commercial purposes, but there is no outstanding key species in this respect. They will therefore be presented summarily as a group. Local names: Macaco (Brazil), mico, mono (in wide use), pichico (Peru, callitrichids), saqui (Brazil, callitrichids). Geographical distribution: The Cebidae family ranges from southern Mexico to northern Peru, along the Pacific slope and as far southeast as northern Argentina. The more ...
The evidence from the semicircular canals suggests that the earliest anthropoids dating to the Late Eocene and Early Oligocene of Egypt were all medium to medium slow in their locomotion. These predictions generally match the hypothesized locomotor behaviours based on postcranial fossil evidence for these Fayum taxa. Catopithecus, Parapithecus and Aegyptopithecus, all predicted to be slow or medium in agility based on postcranial evidence, are also reconstructed as medium to medium slow based on semicircular canal size. Proteopithecus, predicted to be an agile arborealist [27-30], is reconstructed as the fastest of the Fayum anthropoids based on the semicircular canal data. The extant taxon to which Proteopithecus appears most similar in the lateral canal plot is Callimico goeldi, a relatively agile, arboreal New World monkey. In contrast, the results for Apidium are somewhat surprising and contradict expectations. Postcranial remains of Apidium display adaptations to leaping [29,31-36], ...
Dental microwear analysis is conducted on a community of platyrrhine primates from South America. This analysis focuses on the primate community of Cachoeira Porteira (Para, Brazil), in which seven sympatric species occur: Alouatta seniculus, Ateles paniscus, Cebus apella, Chiropotes satanas, Pithecia Pithecia, Saguinus midas, and Saimiri sciureus. Shearing quotients are also calculated for each taxon of this primate community. Dental microwear results indicate significant differences between taxa, but are somewhat insufficient when it comes to discriminating between ecologically similar taxa. The primates of Cachoeira Porteira all incorporate a certain amount of fruit in their diet, entailing a definite amount of inter-specific competition as they must share food resources. Alouatta is the most folivorous taxon of this community, which is corroborated by dental microwear analysis. Ateles, although of a similar size to Alouatta, limits inter-specific competition by incorporating more fruit in its diet.
It is currently thought that New World monkeys, prosimians, and humans are the only primates to possess vomeronasal organs (VNOs) as adults. Recent studies of the human VNO suggest that previous investigations on Old World primates may have missed the VNO. We examined nasal septa from the chimpanzee (Pan troglodytes) grossly and histologically for comparison with nasal septa from humans, Old World monkeys (Macaca fascicularis, M. nemistrina) and prosimian primates (Microcebus murinus, Otolemur garnettii). Grossly, chimpanzees had depressions on the nasal septum similar to fossae reported anterior to the VNO openings in humans. Histologically, chimpanzees and humans had bilateral epithelial tubes which were above the superior margin of the paraseptal cartilages (vomeronasal cartilage homologue). The epithelial tubes had a homogeneous ciliated epithelium. These structures were thus positionally and structurally identical to the human VNO and unlike the well-developed prosimian VNOs which were ...
