| party size and diet of syntopic atelids (ateles chamek and lagothrix cana) in southwestern brazilian amazonia. | syntopic alouatta seniculus, ateles chamek and lagothrix cana (atelidae) were studied in southwestern amazonia. primate populations were first surveyed, and then the party size, diet and vertical spacing were monitored over a 5-month period. atelids accounted for more than half the survey sightings and lagothrix was the most abundant. party sizes recorded for both alouatta and lagothrix during monitoring were significantly larger than those recorded during surveys, but no such difference was fou ... | 2001 | 11713409 |
| geographic distribution and abundance of woolly (lagothrix cana) and spider (ateles chamek) monkeys in southwestern brazilian amazonia. | two species of frugivorous atelids, ateles chamek and lagothrix cana, occur in southwestern brazilian amazonia. populations were surveyed at 36 sites in the state of rondônia. ateles chamek is widespread, but the distribution of l. cana is limited by a combination of riverine barriers and ecological factors, possibly including competition with a. chamek. groups of l. cana were generally larger and more abundant than those of a. chamek, even in syntopy. the transitional forest that predominates i ... | 2002 | 11793413 |
| primate abundance and habitat preferences on the lower urubamba and tambo rivers, central-eastern peruvian amazonia. | we report information on population density, group size, and habitat preferences of primates along the lower río urubamba and in the río urubamba-río tambo interfluvium, in central-eastern peruvian amazonia, an area that has been little explored with regard to its primate fauna. during 425 km of transect walks in october-november 2008 and april-may 2009 totally 174 groups of nine primate species were encountered, the most common being callicebus brunneus (45 groups), saguinus imperator (41 group ... | 2013 | 23661029 |
| strongyloides cebus (nematoda: strongyloididae) in lagothrix cana (primates: atelidae) from the brazilian amazon: aspects of clinical presentation, anatomopathology, treatment, and parasitic biology. | abstract : seven cases of parasitism by strongyloides cebus were identified in lagothrix cana from brazil. aspects of the clinical presentation, treatment, pathology, and parasitic biology of these infections are described. moderate to severe disease was observed, requiring hospitalization of 3 primates, and diarrhea was the most common clinical sign described. one l. cana individual died, for which ulcerative enteritis was the major finding upon histopathological analysis. the use of ivermecti ... | 2013 | 23909511 |
| activity budget and social interactions in semi-captive gray woolly monkeys (lagothrix lagotricha cana) living in an ex situ conservation area in central amazonia. | areas holding primates in semi-captivity conditions represent an excellent opportunity for collecting data on rare, little known, and endangered taxa, contributing with insightful information to help in their conservation. here, we present information on the activity budget and social interactions of the elusive gray woolly monkeys, lagothrix lagotricha cana, in an ex situ conservation area in central amazonia. we studied the behavior of 18 semi-captive individuals through instantaneous scan and ... | 2017 | 28186699 |
| trypanoxyuris (paraoxyuronema) lagothricis (nematoda: oxyuridae) in lagothrix cana (primates: atelidae) from brazil. | during necropsy of a specimen of lagothrix cana (é. geoffroy, 1812) (primates: atelidae) from the brazilian amazon, pinworms were found in the large intestine. the intensity of infection was 64 parasites (17 males and 47 females) and there were no gross pathological changes related to parasitism. after morphological analysis the parasites were identified as trypanoxyuris (paraoxyuronema) lagothricis (buckley, 1931) (nematoda: oxyuridae). this is the first record of this oxyurid species in primat ... | 2013 | 23778825 |
