TITLE:

CYTOGENETIC STUDY OF Hoplias malabaricus (BLOCH 1794) IN TWO RIVERS FROM THE PLATEAU REGION OF THE MUNICIPALITY OF ORIXIMINÁ - PA

KEY WORDS:

Amazon basin, Fish, Taxonomy, Biodiversity

PAGES: 15
BIG AREA: Outra
AREA: Ciências Ambientais
SUMMARY:

The Amazon basin is the largest hydrographic province in South America and is home to more than 2,700 species of freshwater fish. In the last decade, the increase in the description of new fish species and the clarification of taxonomic relationships was driven by evidence obtained by integrative taxonomy analysis. Hoplias malabaricus (traíra) is a controversial nominal taxon that harbors a complex of cryptic species. For decades, recurrent cytogenetic studies have pointed to the presence of different evolutionary units hidden in the H. malabaricus taxon. This proposal will contribute scientifically to the advancement of knowledge about the aquatic biodiversity of the Amazon basin through the resolution of taxonomic uncertainties of the H. malabaricus group. This work aims to investigate the taxonomic status of populations of H. malabaricus from the Amazon basin to highlight possible candidate species and formally describe new species in the group. The specimens of H. malabaricus will be collected in two different areas: Igarapé Alambique and Igarapé Ariramba. The chromosome preparations will be processed in the field. The preserved specimens will have their measurements taken using a digital caliper with a precision of 0.01 mm and a measuring tape. It is expected to evidence new genetic lineages for the genus Hoplias.
