The Bias of combining variables on fish's aggressive behavior studies
Noleto-Filho, Eurico Mesquita; ; Gauy, Ana Carolina Dos Santos ; Bolognesi, Marcela Cesar ; Gonçalves-de-Freitas, Eliane (Behavioural Processes, 2019) [Artigo]
Quantifying animal aggressive behavior by behavioral units, either displays or attacks, is a common practice in animal behavior studies. However, this practice can generate a bias in data analysis, especially when the ... -

Length–weight relations of fishes (Actinopterygii) from karst streams in the bodoquena plateau, western Brazil
Severo-Neto, Francisco; ; ; ; (Acta Ichthyologica et Piscatoria, 2018) [Artigo]
The presently reported study provides the length–weight relations (LWR) for 23 species from headwater streams of the Bodoquena Plateau, which is located on the southern border of the Brazilian Pantanal. The following species ... -
Tactile stimulation reduces aggressiveness but does not lower stress in a territorial fish
Bolognesi, Marcela Cesar; dos Santos Gauy, Ana Carolina ; Gonçalves-de-Freitas, Eliane (Scientific Reports, 2019) [Artigo]
Body tactile stimulation has a positive effect upon highly social animals, such as mammals and cleaner-client coral-reef fish, by relieving stress and improving health. Conversely, some tactile contacts are naturally ... -
Two new species of tenuipalpus sensu stricto (Acari: Tenuipalpidae) from Brazil, with a discussion on the ontogeny of leg setae
