Assessing Fish Community Structure and Diversity Across Environmental Gradients in a Tropical Bay

open access: yesMarine Ecology, Volume 46, Issue 2, March 2025.
ABSTRACT Understanding the relationship between species distribution and the environment across spatial gradients is crucial for biodiversity evaluation. We surveyed fish populations in a tropical bay, covering a spatial gradient from the outer zone with favorable marine conditions to the inner zone affected by human activities.

Otolith edge fingerprints as approach for stock identification of Genidens barbus [PDF]

open access: yesEstuarine, Coastal and Shelf Science, 2017
Abstract The purpose of this paper is to assess the use of multi-elemental otolith fingerprints as a tool to delimit catfish Genidens barbus fish stocks in four estuaries from the southwestern Atlantic Ocean. Barium:Calcium (Ca), Magnesium:Ca, Manganese:Ca, Sodium:Ca and Strontium:Ca ratios in the otolith edge were determined by LA-ICPMS. PERMANOVA

Temporal patterns of fish occurrence of the euryhaline sector of a subtropical estuary, southern Brazil

open access: yesActa Scientiarum: Biological Sciences, 2020
Fish fauna was studied in five sites of the shallow infralittoral of the Paranaguá Bay during the period from October 1999 to September 2000. At each sampling site, fish were sampled with other trawls, salinity and temperature were measured, water ...

On the homologies of the skeletal components of catfish (Teleostei: Siluriformes) suspensorium [PDF]

open access: yes, 2001
There has been much controversy concerning the identity of the components of the suspensorium in Siluriformes (catfishes). This confusion has implications not only for comparative morphology, but also for phylogenetic studies.
