The overdue construction of the Brazilian highway BR-156, which connects Macapá to Oiapoque, is facing a new pressure to be finished. This new connection put together two different agricultural points of view, since in Brazil, alongside the BR-156 highway, some fields of eucalyptus and soy monocultures can be found whereas, in French Guiana, agriculture is mainly characterized by traditional practices. Among the biological perspectives, some issues like biodiversity modification and the increase of potentially plague species both in biological and agricultural aspects can arise. Ants have a key position in most land environments and are also considered good indicators of diversity or disturbance. Leaf-cutting ants of the genera Atta and Acromyrmex are considered the dominant herbivores from the Neotropical zone eventually bringing loss to main crops within the agriculture practices. We propose a bilateral collaborative study between Guianese and Brazilian researchers in order to compare the ant fauna between these two countries, understanding the major impacts that the leaf-cutting ants have on the local crop production. The comparative ant fauna investigation would be performed through the combination of morphological and cytogenetic tools allowing the detection diversity even among similar ant species. We expect to survey the negative biological impact caused by some ant groups under the agriculture grounds, and also contribute to our knowledge on the Amazonian ants both from French Guiana and Brazil. These tasks require the establishment of collaborative partnerships with intensive academic training of undergraduate students and also student exchanges as important educational achievements of this proposal.

Jerome Orivel
Jérôme Orivel is a research director at CNRS. He is working in the field of evolutionary ecology, with particular interests for social insects and the interactions they have developed with other organisms. He is managing the research lab of ‘Biology of Interactions’ at Ecofog which objective focus on the study of the roles of interspecific interactions and environmental factors in shaping biological diversity. During the last years, he has coordinated 1 ANR Young Researchers project and 3 other international/national/regional projects. He was/is also involved in 11 other research projects. He has published ca. 90 papers in international peer- reviewed journals and supervised 5 PhD students, 1 Post-doc, and >20 Master’s degree or undergraduate students.


Jeferson Alves Cardoso de Aguiar
Hilton de Aguiar is the professor of Genetics and Evolution at the Federal University of Amapá (UNIFAP), campus Oiapoque in Brazil since 2013. He is graduated in Biology at Federal University of Viçosa (UFV) with masters and Doctor degree in Genetics and Breeding also by UFV. He focuses his scientific efforts on animal cytogenetics, evolution, taxonomy and myrmecology. Recently he has been working on taxonomic conflicts among some ant species of the genus Camponotus from South America. He is training a group of undergraduate students at the "Laboratório de Formigas" from UNIFAP at Oiapoque to collect, store, assemble and identify the main ant genera of the northern Amapá.
