| the influence of the scout upon the decision-making process of recruited workers in three acromyrmex species (formicidae: attini). | we examined how the information communicated by a scout worker influences the plant species transported by recruited workers in acromyrmex balzani, acromyrmex rugosus, and acromyrmex crassispinus, three species of leaf-cutting ant that have different substrate and habitat preferences. we verified that certain plant species were more likely to be transported than others and that recruitment occurs. we found that recruited workers were more likely to transport non-preferred plant species when they ... | 2004 | 15518996 |
| cytogenetic data on six leafcutter ants of the genus acromyrmex mayr, 1865 (hymenoptera, formicidae, myrmicinae): insights into chromosome evolution and taxonomic implications. | cytogenetic data for the genus acromyrmex mayr, 1865 are available, to date, for a few species from brazil and uruguay, which have uniform chromosome numbers (2n = 38). the recent cytogenetic data of acromyrmex striatus (roger, 1863), including its banding patterns, showed a distinct karyotype (2n = 22), similar to earlier studied atta fabricius, 1804 species. karyological data are still scarce for the leafcutter ants and many gaps are still present for a proper understanding of this group. ther ... | 2016 | 27551345 |
