6. Twigs of Albizia niopoides (Spruce ex Benth.) Burkart as a nesting resource for ants (Hymenoptera: Formicidae)
ABSTRACT Ants can use twigs from fragments of tree branches as a nesting resource. The present study analyzed gatherings of ants in twigs of Albizia niopoides, a Fabaceae native to the Atlantic Forest that is used in landscaping in parks and squares in Brazil. Expeditions were performed in an urban park located in Atlantic Forest areas between February and J

7. Tegumentary leishmaniasis in the State of Amazonas: what have we learned and what do we need?
This study evaluated the occurrence of American tegumentary leishmaniasis (ATL) in the State of Amazonas, Brazil, in the last 30 years with emphasis on the last 10 years (2001 to 2010). The disease was predominantly observed in males (76.2%), in the 21- to 30-year-old age group (26.6%) and in extractive workers (43.7%); 3.3% of the cases were the mucosal for

8. Worker morphology of the ant Gnamptogenys striatula Mayr (Formicidae, Ectatomminae) in different landscapes from the Atlantic Forest domain
Morphological traits, such as size and shape, may reflect a combination of ecological and evolutionary responses by organisms. Ants have been used to evaluate the relationship between the environment and species coexistence and morphology. In the present study, we analyzed the morphology of workers of Gnamptogenys striatula Mayr in different landscapes from

9. Distúrbios osteomusculares relacionados ao trabalho de operadores da colheita florestal mecanizada / Work-related musculoskeletal disorders of operators of mechanized harvesting
The Repetitive Strain Injury / Work Related Musculoskeletal Disorders (LER / DORT) can arise in any field of activity; just there is a causal factor, ie, functions and jobs that expose workers to risk factors. These risk factors are present in the operator of the harvesting machinery activities. Throughout the workday upper limbs are highly required, necessi

12. O papel das rotas e da obtenção de informações sobre a eficiência no forrageio de dinoponera quadriceps em ambiente natural
In this study, we investigated the role of routes and information attainment for the queenless ant species Dinoponera quadriceps foraging efficiency. Two queenless ant colonies were observed in an area of Atlantic secondary Forest at the FLONA-ICMBio of Nisia Floresta, in the state of Rio Grande do Norte, northeastern Brazil, at least once a week. In the fir
