Aerial Jumping in the Trinidadian Guppy (Poecilia reticulata)
Many fishes are able to jump out of the water and launch themselves into the air. Such behavior has been connected with prey capture, migration and predator avoidance. We found that jumping behavior of the guppy Poecilia reticulata is not associated with any of the above.

Eficiência de peixes nativos brasileiros como predadores de larvas de mosquitos
Peixes são uma alternativa no controle biológico de mosquitos. Algumas espécies são comprovadamente eficientes em muitos países, porém não são nativas brasileiras. Espécies brasileiras podem ser larvófagas, porém há carência de informações.

Laterality enhances numerical skills in the guppy, Poecilia reticulata [PDF]
It has been hypothesized that cerebral lateralization can significantly enhance cognition and that this was one of the primary selective forces shaping its wide-spread evolution amongst vertebrate taxa. Here, we tested this hypothesis by examining the link between cerebral lateralization and numerical discrimination.

Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.
