Abstract

PADILLA, DORA NANCY. Spatial Distribution of the Species of the Genus Buenoa (Hemiptera: Notonectidae) in Tumaco (Nariño, Colombia). Acta biol.Colomb. [online]. 2014, vol.19, n.1, pp.83-88. ISSN 0120-548X.  https://doi.org/10.15446/abc.v19n1.38641.

The work was carried in the Mar Agrícola farm of the municipality Tumaco, with the objective of studying the distribution of the species of the genus Buenoa in homogeneous environmental conditions regarding temperature, humidity, altitude and aquatic habitats of the freshwater and the others with different grade of conductivity and dedicated to the marine shrimp farming Litopenaeus vannamei (Boone, 1931). The studied lakes were four of freshwater and four with different conductivity, in the months of June to November 2010. The results showed heterogeneous distribution of the species of the genus Buenoa with major diversity in freshwater (5 species) and lower abundance; while in saltwater had lower diversity (4 species) and major abundance. Only Buenoa dactylis Padilla-Gil 2010 was found in both aquatic environments. It is discussed possible ecological implications than can influence this distribution pattern are discussed.
