Although fewer postcranial remains have been discovered for Hadropithecus than for Archaeolemur, what has been found indicates that both were adapted for a terrestrial or semi-terrestrial lifestyle,[1][5][6][12] an unusual trait for lemurs. Both genera had short limbs and a powerful build.[11] Due to its specialized dentition and likely diet, Hadropithecus is thought to have been the more terrestrial of the two,[12] since Archaeolemur may have sent more time foraging and sleeping in the trees.[5] Both genera also have shortened hands and feet, an adaptation for walking on the ground.[11] The face of Hadropithecus was shortened and adapted to heavy stress from chewing. The monkey lemurs had highly specialized teeth, but Hadropithecus went further by specializing in strong grinding.[15] It had expanded molars that wore down quickly,[11] much like those of ungulates,[1] and its posterior premolars acted like molars to extend the grinding surface.[11] It also had a robust mandible to facilitate ...
This species is listed on Appendix I of CITES. Daubentonia madagascariensis is reported to occur in numerous protected areas, including 13 national parks (Andohahela, Andringitra, Mananara-Nord, Mantadia, Marojejy, Masoala, Midongy du Sud, Montagne d Ambre, Ranomafana, Sahamalaza-Iles Radama, Tsingy de Bemaraha, Tsingy de Namoroka, and Zahamena), seven strict nature reserves (Betampona, Tsaratanana, Makira, Farankaraina, Itampolo, Tsingy de Bemaraha, and Zahamena), and 13 special reserves (Ambatovaky, Analamazaotra, Analamerana, Anjanaharibe-Sud, Ankarana, Bora, Forêt d Ambre, Kalambatritra, Manombo, Manongarivo, Marotandrano, Nosy Mangabe, and Pic d Ivohibe). They are found as well in the forests of Daraina (part of the Loky-Manambato Protected Area), as well as in the Maroala and Anjiamanginana Classified Forests. Yet despite occuring in a great many protected areas, their presence is often based only on signs and infrequent sightings, so there is little understanding of population size ...
The most commonly recurring debate in primatology during the 1970s, 1980s, and early 2000s concerned the phylogenetic position of tarsiers compared to both simians and the other prosimians.[54][55] Tarsiers are most often placed in either the suborder Haplorhini with the simians or in the suborder Prosimii with the strepsirrhines.[47] Prosimii is one of the two traditional primate suborders and is based on evolutionary grades (groups united by anatomical traits) rather than phylogenetic clades, while the Strepsirrhini-Haplorrhini taxonomy was based on evolutionary relationships.[5] Yet both systems persist because the Prosimii-Anthropoidea taxonomy is familiar and frequently seen in the research literature and textbooks.[22]. Strepsirrhines are traditionally characterized by several symplesiomorphic (ancestral) traits not shared with the simians, particularly the rhinarium.[f][47][57] Other symplesiomorphies include long snouts, convoluted maxilloturbinals, relatively large olfactory bulbs, and ...
This report presents the first study of the pressures experienced by the hands (and feet) during quadrupedal locomotion in aye-ayes. Results show that although there is some individual variation, there are clear general trends with regard to hand posture, speed and pressure that characterize aye-aye locomotion. These trends reveal a composite strategy to reduce pressure on long, gracile digits. This study not only confirms previous behavioral data on hand posture but also reveals previously undocumented mechanisms for adaptation to locomotion on larger substrates that are frequently used by aye-ayes in the wild. These are alternative strategies to the postural adaptations, such as knuckle-walking, or morphological changes, such as reduced length of digits, that are documented in other primates, and this study reveals more clearly the plasticity of primate behavior overall. The various behavioral adaptations to digit load reduction shown by aye-ayes in this study may not only be informative for ...
16. Tarsiers are prosimian primates of the genus Tarsius, a monotypic genus in the family Tarsiidae, which is itself the lone extant family within the infraorder Tarsiiformes. The phylogenetic position of extant tarsiers within the order Primates has been debated for much of the past century, and tarsiers have alternately been classified with strepsirrhine primates in the suborder Prosimii, or as the sister group to the simians (=Anthropoidea) in the infraorder Haplorrhini. Analysis of SINE insertions, a type of macromutation to the DNA, is argued to offer very persuasive evidence for the monophyly of Haplorrhini, where other lines of evidence, such as DNA sequence data, had remained ambiguous. Thus, some systematists argue that the debate is conclusively settled in favor of a monophyletic Haplorrhini.Tarsiers have enormous eyes and long feet. Their feet have extremely elongated tarsus bones, which is how they got their name. They are primarily insectivorous, and catch insects by jumping at ...
Epidemiological models often use information on host social contacts to predict the potential impact of infectious diseases on host populations and the efficiency of control measures. It can be difficult, however, to determine whether social contacts are actually meaningful predictors of transmission. We investigated the role of host social structure in the transmission of Escherichia coli in a wild population of primates, Verreauxs sifakas (Propithecus verreauxi). Using multilocus sequence typing (MLST), we compared genetic similarities between E. coli isolates from different individuals and groups to infer transmission pathways. Correlation of social and transmission networks revealed that membership to the same group significantly predicted sharing of E. coli MLST sequence types (ST). Intergroup encounter rate and a measure of space-use sharing provided equally potent explanations for type sharing between social groups when closely related STs were taken into account, whereas animal age, sex and

The golden-crowned or Tattersalls sifaka (Propithecus tattersalli), known locally as ankomba malandy (or akomba malandy, meaning "white lemur"),[3][4][5] was discovered in 1974 north of Vohemar in northeast Madagascar by Ian Tattersall, who observed but did not capture the animal.[3][4] Unsure of its classification, Tattersall provisionally considered it a variant of the silky sifaka in his 1982 book, The Primates of Madagascar,[3][6] citing its mostly off-white to yellowish fur, but also noting its uncharacteristic orange crown patch and tufted ears.[4] Driven by a report in 1986 that the forest where Tattersall had observed this unique sifaka was contracted to be clear-cut for charcoal production, a research team from the Duke Lemur Center, led by Elwyn L. Simons, obtained permits to capture specimens for a captive breeding program.[4] Simons and his team were the first to capture and observe the golden-crowned sifaka,[7] formally describing it as a new species in 1988 and naming it in honor ...

Bobgunnia madagascariensis (Bambara: Samagara), also called the snake bean plant, is a species of legume in the Fabaceae family. Bobgunnia madagascariensis is a small deciduous tree, 3-4 m tall. The plant has large pods that turn dark when ripe. The larvae of Abantis zambesiaca feed on B. madagascariensis. Bobgunnia madagascarensis is toxic. Poison composed of the roasted seeds of Bobgunnia madagascariensis and innards of the beetle Diamphidia nigroornata is applied to the arrows of the Bushmen.[citation needed] Seeds, fruits and stem bark are also used in fishing by poisoning in Africa. The methanolic extract of the fruit of B. madagascariensis contains a saponin tetraglycoside. The root bark of B. madagascariensis contains quinone methide diterpenes. The seed pod contains two acidic saponins, swartziasaponin A and B and swartziagenin, a mixture of oleanolic and 0-acetyloleanolic acid. The pod methanolic extract yields highly glycosylated flavonoids (glycosides of kaempferol and quercetin). The ...

Sifaka (množina »sifake«) so rod iz družine lemurjev v redu prvakov. Njihovo ime je onomatopeja (neposredno izgovorjeno) njihovih značilnih klicev za alarm "si-fak". Kot vse lemurje, jih najdemo le na otoku Madagaskar. Vse vrste sifak so ogrožene, od ranljivih do skrajno ogroženih vrst. Sifake so srednje veliki lemurji z dolžino glave in telesa 40-55 centimetrov in težo od 3 do 6 kilogramov. Njihov rep je ravno tako dolg kot telo, kar jih razlikuje od ostalih lemurjev. Njihovo krzno je dolgo in svilnato, barva pa se med posameznimi vrstami spreminja od rumenkasto bele do črno rjave. Okrogel obraz brez dlake je vedno črn. Kot pri vseh lemurjih ima tudi sifaka posebne prilagoditve za negovanje, vključno z WC-krempljem na svojem drugem nožnem prstu in zobnim glavnikom. Sifake se premikajo z oklepanjem in skakanjem, pri čemer so vedno obrnjeni z glavo navzgor, ko skačejo z debla na deblo in se premikajo med vejami. So vešči plezalci in močni skakalci; zmožni so skočiti celo do ...

AU - Zamboni, Luciano. PY - 1990. Y1 - 1990. N2 - The presence of germinal cells outside of the embryonal and fetal gonads of the strepsirhine prosimian Galago crassicaudatus crassicaudatus is described. Forty‐three embryos and fetuses from day 26 or 27 of gestational age to near term were studied: more than 90% possessed germinal cells in ectopic sites situated either far from (extragonadal ectopism) or close to the gonads (perigonadal ectopism). The first sites were the walls of the aorta and mesenteric artery, the stroma between the aorta and the cardinal vein and the retroperitoneal neuroganglia. The second were the mesenchyme dorsal to the gonads and around the vestigia of the mesonephric glomeruli and tubules, and the rete ovarii and testis. The ectopic cells were generally present in conspicuous numbers, in some ...

Despite great interest and decades of research, the musculoskeletal relationships of the masticatory system in primates are still not fully understood. However, without a clear understanding of the interplay between muscles and bones it remains difficult to understand the functional significance of morphological traits of the skeleton. Here, we aim to study the impacts of the masticatory muscles on the shape of the cranium and the mandible as well as their co-variation in strepsirrhine primates. To do so, we use 3D geometric morphometric approaches to assess the shape of each bone of the skull of 20 species for which muscle data are available in the literature ...
Spectral tarsiers have a small, round body covered in soft, velvety fur. Their pelage ranges from gray to buff-gray in color. They have long scaly tails with tufts of fur only present on the distal third of the tail. Spectral tarsiers exhibit sexual dimorphism: females weigh 102 to 114 g while males weight 118 to 130 g.. Members of the genus Tarsius possess long, slender hands, feet, and digits. Their hands are thought to be the longest of any living primate relative to body size. These extremely elongated hands are designed for clinging and gripping despite the lack of opposable thumbs. The third finger of T. tarsier is extremely long and slender and is only 15% shorter than the humerus. This trait is not symmetrically reproduced from the anterior to the posterior, as the fourth digit is the longest of the hindlimb digits. The second and third digits of the hindlimb are equipped with specialized toilet claws. Spectral tarsiers are thought to be the most primitive tarsiers, as they lack disks on ...
Ang karamihan sa mga hayop at halaman ay may kakayahang mag-sintesis(synthesize) ng kanilang sariling bitamina C sa pamamagitan ng sekwensiya ng apat na pinapatakbo ng enzyme na mga hakbang na kumokonberte sa glucose patungo sa bitamina C[2]. Ang glucose na kailangan upang mag-sintesis ng ascorbate sa atay(sa mga mammal at mga ibon na nagsasagawa ng perching) ay kinakatas mula sa glycogen. Ang sintesis ng ascorbate ay isang nakabatay sa glycogenolisis na proseso. Sa mga reptilya at mga ibon, ang biosintesis ay isinasagawa sa mga kidney nito[3]. Kabilang sa mga hayop na nawalan ng kakayahan na mag-sintesis ng sariling bitamina C ang mga simian at tarsier na ang pinagsamang ito ay bumubuo sa dalawang pangunahing mga suborder ng primate na anthropoidea na tinatawag ring haplorrhini.

Tarsiers are among the smallest haplorhine primates (80-150 g), and their diet is based on insects and other small animal prey [27]. Tarsius sirindhornae was a large species of Tarsius, as large as or possibly larger than T. bancanus, the largest extant Tarsius. We used the regression equation of the M1 area against body weight proposed by Gingerich [28] for Tarsius and obtained an estimated body weight of T. sirindhornae of 90-180 g. Its body mass places it below Kays threshold of 500 g, below which primates cannot be obligate folivores owing to fundamental metabolic constraints [29]. Some specimens of T. sirindhornae display a high degree of premolar and molar wear with horizontal wear facets, suggesting a dietary difference from most other tarsiers. Its large premolars and molars, with enlarged M3 and low and less acute molar cusps, also point towards a less insectivorous and carnivorous diet than the extant and fossil Tarsius and even other fossil Tarsiidae. The meaning of such an odd ...
