Scott
Schaefer's Fieldwork in Brazil - SAS95
The 1995 Academy of
Natural Sciences of Philadelphia (ANSP) and Museo de
Ciencias (MCP), Pontificia Universidad Catolica do Rio
Grande do Sul (PUCRS) in Porto Alegre expedition was the
second of two expeditions to Brazil funded by a grant to
Scott Schaefer from the National Science Foundation in
support of monographic research on Otocinclus. The personnel consisted of S.
Schaefer and W. Saul of ANSP, J. Garavello from UFSCar,
and R. Reis and students from PUCRS. The purpose of this
expedition, in addition to assembling a comprehensive
collection of fishes, was to survey the Atlantic coastal
streams north of Rio de Janeiro for additional
populations of Otocinclus.
Species of
Otocinclus
were known from the lower
Paraná and Atlantic coastal streams of Santa Catarina
State and areas to the south, but no collections or
reports indicated the presence of Otocinclus in areas of eastern Brazil north of Rio
de Janeiro (Thayer Expedition specimens were collected in
the vicinity of Rio in the 1860's; however, no recent
collections had obtained additional Otocinclus specimens from that region). This
expedition failed to locate populations in the area,
which strengthened the case for the absence of
Otocinclus
from this region.
