Abstract This study evaluated the anesthetic activity of essential oil from Lippia alba (EOLA), linalool chemotype in a euryhaline fish (fat snook Centropomus parallelus). In the first experiment, fish were exposed to 30, 80, 130, 180, 200, and 230

Alterations, such as drainage network reorganization, in the landscape in the Amazon basin influence the distribution range and connectivity of aquatic biota and, therefore, their evolution. River capture is a geomorphic mechanism of network reorgani

Photoperiod is considered an important synchronizer of biological activities and endocrine pathways, including growth. As ectotherms, fish have many physiological functions controlled by the photoperiod. However, the combined effects of photoperiod a

Background In the wild, matrinchã (Brycon amazonicus) and tambaqui (Colossoma macropomum) rely strongly on their swimming capacity to perform feeding, migration and reproductive activities. Sustained swimming speed in fishes is performed almost excl

The structural organization and histo-cytochemical features of dorsal skin of Ancistrus dolichopterus (acari bodo) are the main focus of this work. The epidermis, dermis and subcutis are the principal layers of the skin. The epidermis mainly consists

Abstract Biodiversity is much more than what we see. Biodiversity also includes a number of microorganisms, such as bacteria, fungi and viruses, many of which cause disease in animals, plants and man. In the Amazon, many of these organisms live in th

We investigated how natural dissolved organic matter (DOM) of the Rio Negro (Amazon) affects acute copper (Cu) toxicity to local fish: the cardinal tetra (Paracheirodon axelrodi) and the dwarf cichlid (Apistogramma agassizii). It is established that
