  • Conservation of the Brown Howler Monkey in South-East Brazil
    ORYX VOL 28 NO 1 JANUARY 1994 Conservation of the brown howler monkey in south-east Brazil Adriano Garcia Chiarello and Mauro Galetti The brown howler monkey Alouatta fusca once had a wide geographical distribution throughout a large part of the Atlantic forest in Brazil. Today only 5 per cent of these forests remain and the species is endangered. Howler monkeys can thrive in small forest fragments but they are more vulnerable to hunting, disease, and predation in these habitats than in undisturbed forests. Brown howler monkeys are important seed dispersers of several plant species, particularly in isolated forest fragments where specialized frugivores are absent. In protected areas without large predators howlers can reach high densities and the management of these populations is necessary to avoid inbreeding. Introduction on free-ranging brown howler monkeys started only recently (Mendes, 1989; Prates et The Atlantic forest of Brazil originally ex- al., 1990; Chiarello, 1992; Galetti, 1992).

Mammals compose one of the better studied animal groups; occur in a great diversity of environments, and present distinct and Bruno Sávio Freire interesting behaviors. It has been estimated the existence of approximately 5,000 mammal’s species in the whole world, mostly rodents (40%) and bats (20%). In Brazil it has been reported the occurrence of 530 mammals’ species, among these 66 are threatened. The drastic antropic changes that Brazilian Atlantic Forrest had experienced in the last 150 years, as consequence of the expansion of urban and rural areas, besides hunting and illegal trade, had caused habitat fragmentation and severe reduction in populations’ sizes, resulting in serious threats to mammalian species, specially the larger ones. Celso Margraf Maned-Three-Toed-Sloth, Bradypus torquatus Of 250 mammalian species registered in the Brazilian Atlantic Rain Forest, 55 are endemic to this biome and 38 are threatened. Also, some species have already disappeared in certain regions and localities. For these reasons, with the legal support of the Ordinance 316/2009 of the Ministry of Environment and ICMBio, it was established a covenant with society defining strategies to recover Black-Faced-Lion-Tamarin, Leontopithecus caissara these species in the form of a national action plan. THE PLAN The National Action Plan (NAP) for the conservation of central Atlantic Forest Mammals has a geographic approach, rather than specific, including the states: Espírito Santo, São Paulo, Rio de Janeiro, and part of Minas Gerais, Bahia and Paraná, in a region under high human pressure and of great relevance in Brazil’s socioeconomic scenario.

  • Primate Families-Short
    The Primates compiled by Dana Visalli A male Mandrill Primates arose from ancestors that lived in the trees of tropical forests; many primate characteristics represent adaptations to life in this challenging three-dimensional environment. Most primate species remain at least partly arboreal. There are a surprisingly large number of primates, or ‘monkeys and their kin.’ The total number is variable, but settles in the range of approximately 325 species. The word ‘primate’ comes from a Latin root meaning ‘first rank’ or ‘numeral uno,’ a reflection of ever-present an- thropocentrism (human self-centeredness) of our species, which tends to judge nearby Homo sapiens (which means ‘wise man’) as the pinnacle of the infinitely long evolutionary journey, while those Homo sapiens at a distance are often considered to be ‘the other’ and ‘the enemy’ and therefore not wise at all. Primates range in size from a tiny lemur in Madagascar called Madame Berthe’s Mouse Lemur, which weighs one ounce, to the lowland gorillas in Africa, which weigh in at well over 400 pounds. Genetic studies indicate that the primate line originated about 85 million years ago, in the mid-Cretaceous Peri- od. New primate species are still being discovered. More than 25 species were taxonomically described in the decade of the 2000s and eleven have been described since 2010. Primates are characterized by large brains relative to other mammals, as well as an increased reliance on stereoscopic vision at the expense of smell, the dominant sensory system in most mammals. These features are more developed in monkeys and apes and noticeably less so in lorises and lemurs.

  • Alouatta Caraya ); Acoustics, Function and Applications for Welfare
    Howl vocalisations of captive black and gold howler monkeys (Alouatta caraya ); acoustics, function and applications for welfare. Submitted by Holly Lavinia Antonia Farmer, to the University of Exeter as a thesis for the degree of Doctor of Philosophy in Psychology in July 2011 This thesis is available for Library use on the understanding that it is copyright material and that no quotation from the thesis may be published without proper acknowledgement. I certify that all material in this thesis which is not my own work has been identified and that no material has previously been submitted and approved for the award of a degree by this or any other University. 1 ABSTRACT This thesis aims to determine the function of howl vocalisations performed by the black and gold howler monkey, Alouatta caraya , and to examine the connections between howling, welfare and breeding in captivity. Comparisons of the behaviours performed during natural howling bouts and during howling bouts in response to experimental playbacks provide evidence for a range of howl functions including regular advertisement of the caller’s occupancy and mate defence and attraction. Detailed analyses of howl call acoustics provide the first evidence of both individuality and context-specificity in the calls of A. caraya males. These findings further support the functions of intergroup spacing, mate defence and attraction and suggest that howling may act as an honest signal of male quality. Experimental playbacks of conspecific calls stimulated howling by captive male A. caraya and affected other behaviour patterns suggesting that playbacks are an effective form of environmental enrichment to enhance captive welfare.

  • Primates in Peril – the World’S Top 25 Most Endangered Species
    Primates in Peril – the World’s Top 25 Most Endangered Species Mountain galago (Paragalago orinus) – Tanzania (numbers unknown) Found in Tanzania, this is one of the smallest of all galago species. Their habitat has been affected by agricultural expansion and illegal logging. Their population is very fragmented in forests across seven isolated mountain blocks. Their conservation status has been at Near Threatened since 2008. Roloway monkey (Cercopithecus roloway) – Côte d’Ivoire and Ghana (very few remain, possibly fewer than 100) The roloway monkey is one of the most endangered monkeys in Africa. Illegal logging has destroyed large areas of the forests in Ghana where they live. Trees have also been cleared for charcoal production. They are also hunted. Without effective conservation they could become extinct. The captive population is so small that extinction in captivity is also a strong possibility. White-thighed Colobus (Colobus vellerosus) – Nigeria (numbers unknown) One of four species of black-and-white colobus monkeys in Africa. Unregulated hunting is the main reason for the demise of this species across a very large part of its range, although habitat loss and degradation have also contributed significantly to population decline. The fall in their numbers has been relatively neglected in comparison with other threatened West African primates. Niger Delta red coloBus monkey (Piliocolobus epieni) – Nigeria (numbers as few as 1,000) The red colobus monkeys are probably more threatened than any other group of primates in Africa. As a result of habitat destruction and hunting, the population has declined significantly since the 1990s and may now be 90 per cent lower than the previous estimate of 10,000.

  • On the Origin of Allopatric Primate Species
    Biodiversity Journal, 2016, 7 (1): 117–198 MONOGRAPH On the origin of allopatric primate species Marc G.M. van Roosmalen* & Tomas van Roosmalen ¹MVRS - Marc van Roosmalen Stichting, Leiden, The Netherlands *Corresponding author, e-mail: [email protected] ABSTRACT Here we present a theory on the origin of allopatric primate species that follows - at least in Neotropical primates - the irreversible trend to albinotic skin and coat color, called “meta- chromic bleaching”. It explains why primates constitute such an exceptionally diverse, species-rich, and colorful Order in the Class Mammalia. The theory is in tune with the principle of evolutionary change in tegumentary colors called “metachromism”, a hypothesis propounded by the late Philip Hershkovitz. Metachromism holds the evolutionary change in hair, skin, and eye melanins following an orderly and irreversible sequence that ends in loss of pigment becoming albinotic, cream to silvery or white. In about all extant sociable Neo- tropical monkeys we identified an irreversible trend according to which metachromic varieties depart from the saturated eumelanin (agouti, black or blackish brown) archetypic form and then speciate into allopatric taxa following the trend to albinotic skin and coat color. Speci- ation goes either along the eumelanin pathway (from gray to silvery to cream to white), or the pheomelanin pathway (from red to orange to yellow to white), or a combination of the two. The theory represents a new and original evolutionary concept that seems to act indef- initely in a non-adaptive way in the population dynamics of male-hierarchic societies of all sociable primates that defend a common territory.
