  • PHYLOGENETIC RELATIONSHIPS AMONG BRAZILIAN HOWLER MONKEYS, GENUS Alouatta (PLATYRRHINI, ATELIDAE), BASED on Γ1-GLOBIN PSEUDOGENE SEQUENCES
    Genetics and Molecular Biology, 22, 3, 337-344 Phylogenetic(1999) relationships of Brazilian howler monkeys 337 PHYLOGENETIC RELATIONSHIPS AMONG BRAZILIAN HOWLER MONKEYS, GENUS Alouatta (PLATYRRHINI, ATELIDAE), BASED ON γ1-GLOBIN PSEUDOGENE SEQUENCES Carla Maria Meireles1, John Czelusniak1, Stephen F. Ferrari2, Maria Paula Cruz Schneider2 and Morris Goodman1 ABSTRACT The genus Alouatta (howler monkeys) is the most widely distributed of New World primates, and has been arranged in three species groups: the Central American Alouatta palliata group and the South American Alouatta seniculus and Alouatta caraya groups. While the latter is monotypic, the A. seniculus group encompasses at least three species (A. seniculus, A. belzebul and A. fusca). In the present study, approximately 600 base pairs of the γ1-globin pseudogene were sequenced in the four Brazilian species (A. seniculus, A. belzebul, A. fusca and A. caraya). Maximum parsimony and maximum likelihood methods yielded phylogenetic trees with the same arrangement: {A. caraya [A. seniculus (A. fusca, A. belzebul)]}. The most parsimoni- ous tree had bootstrap values greater than 82% for all groupings, and strength of grouping values of at least 2, supporting the sister clade of A. fusca and A. belzebul. The study also confirmed the presence of a 150-base pair Alu insertion element and a 1.8-kb deletion in the γ1-globin pseudogene in A. fusca, features found previously in the remaining three species. The cladistic classification based on molecular data agrees with those of morphological studies, with the monospecific A. caraya group being clearly differentiated from the A. seniculus group.

  • Fascinating Primates 3/4/13 8:09 AM Ancient Egyptians Used Traits of an Ibis Or a Hamadryas Used Traits Egyptians Ancient ) to Represent Their God Thoth
    © Copyright, Princeton University Press. No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. Fascinating Primates Fascinating The Beginning of an Adventure Ever since the time of the fi rst civilizations, nonhuman primates and people have oc- cupied overlapping habitats, and it is easy to imagine how important these fi rst contacts were for our ancestors’ philosophical refl ections. Long ago, adopting a quasi- scientifi c view, some people accordingly regarded pri- mates as transformed humans. Others, by contrast, respected them as distinct be- ings, seen either as bearers of sacred properties or, conversely, as diabolical creatures. A Rapid Tour around the World In Egypt under the pharaohs, science and religion were still incompletely separated. Priests saw the Papio hamadryas living around them as “brother baboons” guarding their temples. In fact, the Egyptian god Thoth was a complex deity combining qualities of monkeys and those of other wild animal species living in rice paddies next to temples, all able to sound the alarm if thieves were skulking nearby. At fi rst, baboons represented a local god in the Nile delta who guarded sacred sites. The associated cult then spread through middle Egypt. Even- tually, this god was assimilated by the Greeks into Hermes Trismegistus, the deity measuring and interpreting time, the messenger of the gods. One conse- quence of this deifi cation was that many animals were mummifi ed after death to honor them. Ancient Egyptians used traits of an ibis or a Hamadryas Baboon (Papio hamadryas) to represent their god Thoth.

  • Diets of Howler Monkeys
    Chapter 2 Diets of Howler Monkeys Pedro Américo D. Dias and Ariadna Rangel-Negrín Abstract Based on a bibliographical review, we examined the diets of howler mon- keys to compile a comprehensive overview of their food resources and document dietary diversity. Additionally, we analyzed the effects of rainfall, group size, and forest size on dietary variation. Howlers eat nearly all available plant parts in their habitats. Time dedicated to the consumption of different food types varies among species and populations, such that feeding behavior can range from high folivory to high frugivory. Overall, howlers were found to use at least 1,165 plant species, belonging to 479 genera and 111 families as food sources. Similarity in the use of plant taxa as food sources (assessed with the Jaccard index) is higher within than between howler species, although variation in similarity is higher within species. Rainfall patterns, group size, and forest size affect several dimensions of the dietary habits of howlers, such that, for instance, the degree of frugivory increases with increased rainfall and habitat size, but decreases with increasing group size in groups that live in more productive habitats. Moreover, the range of variation in dietary habits correlates positively with variation in rainfall, suggesting that some howler species are habitat generalists and have more variable diets, whereas others are habi- tat specialists and tend to concentrate their diets on certain plant parts. Our results highlight the high degree of dietary fl exibility demonstrated by the genus Alouatta and provide new insights for future research on howler foraging strategies. Resumen Con base en una revisión bibliográfi ca, examinamos las dietas de los monos aulladores para describir exhaustivamente sus recursos alimenticios y la diversidad de su dieta.

  • Opossum Didelphis Virginiana
    Opossum Didelphis virginiana Other common names Virginia Opossum, possum Introduction The opossum is the only marsupial found in the United States. Like kangaroos, another well- known marsupial, opossums carry their young in a pouch called a marsupium for the early stages of development after birth. Once they’ve matured a bit, they climb out and hang onto their mother’s back. Opossums are also known for their habit of “playing dead” when threatened, leading to the phrase “playing possum”. Physical Description and Anatomy Opossums have short legs and a thick body. Their fur is coarse and grey to greyish-brown, with a white face. They have a pointed snout with a pink nose and prominent whiskers, beady eyes, and lots of sharp teeth. The ears are black and hairless, and the round, scaly tail is pink and also hairless. The tail is prehensile, used for gripping on to branches while climbing. The innermost toe of the hind foot, called a hallux, is opposable and clawless. Adults weigh anywhere from 4 – 15 lbs (1.8 – 6.8 kg). This weight varies seasonally, and they are often heaviest in the fall, in preparation for winter. Total length is 13-28 inches (33.0 – 71.1 cm). Males are generally larger Opossum skull. than females. Opossum pelt. Identifying features (tracks, scat, calls) Opossums will often use roads and trails created by humans to travel. Their tracks are very distinctive, with the widespread toes and the hallux on the hind foot. Tracks may or may not be accompanied by tail drag marks. Listen for growling or hissing, which indicates an opossum that feels threatened.

  • ABSTRACT the Genus Callicebus Is One of the Most
    Volume ##(##):A‑P, #### NEW SPECIES OF TITI MONKEY, GENUS CALLICEBUS THOMAS, 1903 (PRIMATES, PITHECIIDAE), FROM SOUTHERN AMAZONIA, BRAZIL JULIO CÉSAR DALPONTE1 FELIPE ENNES SILVA2 JOSÉ DE SOUSA E SILVA JÚNIOR3 ABSTRACT The genus Callicebus is one of the most diverse Neotropical primate groups, with 31 recog- nized species. However, large knowledge gaps still exist regarding the diversity of this genus. Such gaps are gradually being filled due to recent intensification of sampling efforts. Several geographic distributions have been better delimited, and six new species have been described in the last 15 years. The goal of the present study is to describe a new species of Callicebus belonging to the Callicebus moloch species group, recently discovered in an area previously considered to be part of the geographic distribution of C. cinerascens. Data collection was conducted through direct observations, specimen collection and interviews with local residents during four expeditions. Specimens were deposited in the mammalian collection of the Mu- seu Paraense Emílio Goeldi. For a comparative evaluation, we examined specimens of the other species of the Callicebus moloch species group, especially the geographically neighboring forms, C. bernhardi and C. cinerascens. We examined 10 chromatic characters of the fur. In addition to body mass, we verified the conventional external variables and 26 craniomet- ric variables. The new species differs from all other Amazonian Callicebus by an exclusive combination of characters, being easily distinguished by the light gray line of the forehead, dark ocher sideburns and throat, dark gray portions of the torso and flanks, and uniformly orange tail. The geographic distribution of the new species is limited by the Roosevelt and Aripuanã rivers, in the states of Mato Grosso and Amazonas, Brazil.

The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae. The total analysis strongly supports the monophyly of the Cebidae family, group- ing Aotus, Cebus and Saimiri with the small callitrichines. In the callitrichines, the data link Cebuela to Callithrix, place Callimico as a sister group of Callithrix/Cebuella, and show Saguinus to be the earliest offshoot of the callitrichines. In the family Pithecidae, Callicebus is the basal genus. Finally, combined molecular data showed congruent branching in the atelid clade, setting up Alouatta as the basal lineage and Brachyteles-Lagothrix as a sister group and the most derived branch.
