The home range of one group of the Geoffroy's marmoset (Callithrix geoffroyi) was studied in a fragment of the Atlantic Forest in south-eastern Brazil, between February 1993 and January 1994. The total home range was 23.3 ha and the area used in the dry season was significantly larger than that of the wet season. The smallest distance travelled by group was 480 m/day in May and the longest was 1,980 m/day in March, but with no significant differences between seasons. The total home range used for this species agrees with the ecological grouping of the genus Callithrix proposed by Rylands & Faria (1993) and may be associated with the habitat structure, the limit of the fragment and the inexistence of neighbouring groups.
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non‐detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non‐governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer‐reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non‐detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio‐temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large‐scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data.
This study examined the removal of seeds of the exotic jackfruit Artocarpus heterophyllus (Lamarck) by mammals in a native forest area with predo minance of jackfruit trees in the Duas Bocas Bio logical Reserve, Southeastern Brazil. The seed removal experiments were made in an area with the predominance of jackfru it trees and in an native forest between January and October 2010. At each samp ling area three distinct treat ments (control: seeds that can be accessed by any species of mammals; semi-protected: seeds that can be accessed only by species of small mammals; and protected: seeds that can not be accessed by any species of ma mma ls) were d isplayed containing seeds of A. heterophyllus. The area predominated by jackfru it trees showed a greater removal o f seeds (35.6%) co mpared to the native forest (21.6%). The results showed that there was no significant difference in the amount of seeds removed fro m each area in the protected and control treatments. However, there was a higher seed removal in the semi-protected treatment in jackfruit trees area. In the native forest the removal was significantly h igher in the control than in the other treatments. In the jackfruit trees area, the removal of seeds in the control was significantly higher than in the protected treatment. Of the species recorded by camera traps, Trinomys paratus can be considered the main disperser in the jackfruit area, contributing to the dispersal of A. heterophyllus, an invasive plant species. Thus, a management plan for A. heterophyllus at the Duas Bocas Biological Reserve should be carried out partially , gradually and slowly, so that the populations of vertebrate species that now depend on this resource for food do not suffer a drastic impact.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
