Numeracy
The more statistical analyses performed in the analysis of research data, the more likely it is that one or more of the conclusions will be in error. Multiple statistical analyses can occur when the sample contains several subgroups and the researchers perform separate analyses for each subgroup. For example, separate analyses may be done for different ethnic groups, different levels of education, and/or for both genders. Media reports of research frequently omit information on the number of subgroup analyses performed thus leaving the reader with insufficient information to assess the validity of the conclusions. This article discusses the problems with …
Phototactic Behaviour Of Subterranean Copionodontinae Pinna, 1992 Catfishes (Siluriformes, Trichomycteridae) From Chapada Diamantina, Central Bahia, Northeastern Brazil, Bianca Rantin, Maria Elina Bichuette
Phototactic Behaviour Of Subterranean Copionodontinae Pinna, 1992 Catfishes (Siluriformes, Trichomycteridae) From Chapada Diamantina, Central Bahia, Northeastern Brazil, Bianca Rantin, Maria Elina Bichuette
International Journal of Speleology
The phototactic behaviour of three Copionodontinae (Trichomycteridae) catfish species (two troglobites and one epigean) from Chapada Diamantina was studied in order to detect modifications related to isolation in the subterranean environment. Differences in response under different luminosities were detected and, unlike other cavefish, Copionodontinae cave species have shown to be more photophobic than the epigean syntopic to them. The troglobitic Glaphyropoma spinosum is the most photophobic, presenting this behaviour under all light intensities, and more homogeneous regarding morphological characters. It suggests that this population is probably isolated for a longer time in the subterranean environment compared to Copionodon sp. n., …
