| Abstract | Quantifying circulating nutrient concentrations in sera of free-ranging subjects will help to establish a basis from which we can evaluate the nutritional status and needs of the captive population. We collected serum samples from 26 free-ranging black-and-gold howlers (Alouatta caraya) in San Cayetano forest in northern Argentina. We analyzed them for concentrations of lipoproteins; amino acids; vitamins A, D, and E; carotenoids; and minerals. There are a few significant differences between sexes in concentrations of high-density lipoprotein cholesterol, certain amino acids, vitamin E, lutein + zeaxanthin, and copper. Most nutritional parameters are similar to the ones measured in free-ranging Mexican mantled howlers (Alouatta palliata mexicana) and in captive New World primates (NWPs). Carotenoid, vitamin D, and phosphorus concentrations are the exceptions. Carotenoid concentrations are higher in free-ranging Alouatta caraya than reported for other free-ranging and captive species. Vitamin D concentrations are 14 times greater in the free-ranging black-and-gold howlers than in captive NWPs. Phosphorus concentrations are also higher than expected and higher than typically occur in captive primates, leading to a 1:1.6 calcium:phosphorus ratio. Because we based our study on a small number of free-ranging howlers, additional samples from different regions and throughout the year would better define desirable nutritional parameters for captive howlers. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
