Abstract
The present paper describes a new occurrence of the species Brachyhypopomus gauderio Giora and Malabarba, 2009 in the Taim Ecological Reserve, Rio Grande do Sul state, Brazil.
Highlights
On November 05th 2003, we collected twelve female specimens of B. gauderio, with average total length of 94.5±13.5mm and average total weight of 2.03±0.81g, in a wetland area (32°32’25” S, 52°32’24” W) adjacent to the BR-471 highway in the Taim Ecological Reserve, in southern Brazil (Figure 2)
The latest fish inventory available for the Taim Ecological Reserve (Garcia et al 2006) did not mention B. gauderio among the 62 fish species reported to occur in several freshwater sites of this ecological reserve
The present work reports for the first time the occurrence of this recently described species of electric fish, B. gauderio, in this important conservation area in southern Brazil. This Federal Reserve created in 1978 harbors a unique freshwater wetland ecosystem encompassing a variety of habitats such as beaches, dunes, forests, grasslands and, especially, lakes and wetlands (Motta Marques et al 2002)
Summary
On November 05th 2003, we collected twelve female specimens of B. gauderio, with average total length of 94.5±13.5mm and average total weight of 2.03±0.81g, in a wetland area (32°32’25” S, 52°32’24” W) adjacent to the BR-471 highway (km-495) in the Taim Ecological Reserve, in southern Brazil (Figure 2). Brachyhypopomus gauderio is widely distributed in the central, southern and coastal regions of the Rio Grande do Sul (RS) state, southern Brazil, especially in lagoons, rivers margins, slow-moving creeks and flood areas
