“…Giant Otters can be easily located because of their noisy diurnal habits and conspicuous campsites. These characteristics, combined with the high value of their pelts ($US 27-90 or more) (Doughty & Myers, 1971;Donadio, 1978;Ayres & Best, 1979), led to extensive uncontrolled hunting in the 1950s and 1960s. Official statistics indicate that over 40 663 pelts were exported from Brazil alone from 1960 to 1967 (Best, 1984).…”

Biology and conservation of the Giant Otter Pteronura brasiliensis

The Giant Otter Pferonuru brasifiensis (Zimmermann, 1780) is endemic to South America, distributed throughout the Orinoco, Amazon and La Plata River basins and numerous localities in the Guyanas. This otter is the largest member of the family Mustelidae, clearly distinguished from other South American otter species by morphological and behavioural characteristics. Large-scale pelt hunting in the 1950s and 1960s led to the classification of the species as 'vulnerable' by the World Conservation Union (IUCN, 1990). Habitat degradation and destruction now present the largest threat to remaining populations. The current distribution of the Giant Otter is presented, emphasizing recent information collected in the Amazon Basin. Morphology, systematics, habitat, behaviour, diet, predation, competition, reproduction, development and physiology are discussed. New data on habitat use and preference, behaviour and diet in northern Amaz6nia are included, and recommendations for future conservation measures are made. Because of the decimation of the Giant Otter in its southern distribution and the habitat destruction occurring in the remainder of its range, we recommend that this species be elevated to 'endangered' status in the IUCN Red Data Book.

“…The Amazonian Manatee is the smallest of the sirenians, reaching between 2.8 and 3.0 m in total length and up to 450 kg in weight (Ayres & Best, 1979;Caldwell & Caldwell, 1985;Rosas, 199 1 ). There are no differences in size between the sexes.…”

Biology, conservation and status of the Amazonian Manatee Trichechus inunguis

The Amazonian Manatee Trichechus inunguis (Natterer, 1883) is the only exclusively freshwater sirenian and the smallest of the living species. Its inability to reduce peripheral heat loss limits its distribution to tropical waters. The species is endemic to the Amazonian region, being distributed throughout the Amazon basin, occurring mainly in calm waters and lakes. The species has been commercially exploited since 1542, with the meat and hide being the main products extracted. This commercial exploitation, combined with their very low reproductive rate, has seriously reduced the manatee population. Therefore the Amazonian Manatee is now considered an endangered species. Although it is protected by most of the countries where it occurs, there is no law enforcement, and the species is still captured throughout the Amazon. Data on general biology, physiology and management of the Amazonian Manatee, as well as its status and recommendations for its conservation, are presented.

“…The adverse consequences of creating iso lated reserves, with the formation of genetic islands or artificial refuges, have been pointed out by Ayres and Best [53], Thorington [54] suggested that reserves of at least 10,000 ha are needed to protect small population of callitrichids, with appropriate management.…”

Feeding Ecology of Saguinus bicolor bicolor (Callitrichidae: Primates) in a Relict Forest in Manaus, Brazilian Amazonia

This study is part of a long-term ecological study of habitat and dietary requirements of the pied bare-face tamarin (Saguinus bicolor bicolor). One group was studied for 11 months in an area of secondary forest in a suburb of Manaus, Amazonas, Brazil. Three main vegetation types occurred inside the group’s home range (12 ha): capoeira, older secondary forest and campinarana (white sand forest). The tamarins ate fruits (21 species), flowers (1 species), exudates (4 species), and arthropods (insects and spiders). They spent 14.3% of total activity time seeking and eating animal prey, and 9.9% feeding on plant material, mostly fruits. In general, fruits consumed were ripe, small and succulent. Trees used for feeding were low and had small crown diameters. Three plant species (Protium aracouchinni, Myrcia cf. fallax, and Couma utilis) were used intensively during the three seasons covered by the study period. The concentrated use of 3 fruit species, each for an extended period (one fruiting species per season), provided the tamarins with a regular food supply. Tamarins consumed exudates from holes in the bark of trees of the families Anacardiaceae and Vochysiaceae, as well as gum exuded from seed pods of Mimosaceae. Exudates were exploited during the dry season and at the beginning of the wet season. Group travel was primarily based on routes connecting the fruiting trees exploited, with foraging for animal prey occurring during travel. Tamarins searched for arthropods on trunks, branches and leaves and in trunk holes. The foraging and feeding tactics displayed by S. b. bicolor are closely linked to morphological characteristics (small size and weight, claw-like nails) that allowed access to energy-rich resources (arthropods and plant exudates) in different strata of the vegetation.
