Fluctuating asymmetry and organosomatic indexes in fish: the Corocoro grunt as a case study (Haemulidae)

Anais da Academia Brasileira de Ciências, 2021
Fluctuation asymmetries (FA) are random on the bilateral symmetry plan of paired morphological characters, and other types of symmetry, such as: for instance, translational or rotational symmetry, in response to environmental, and genetic stress.

Assessing conservation priorities for seahorses in Brazil reveals gaps in current protected areas

Conservation Science and Practice, Volume 7, Issue 6, June 2025.
Abstract Seahorses are rare and threatened marine species facing increasing risks from habitat degradation and overexploitation. Understanding their distribution is critical for effective conservation planning, yet comprehensive studies are limited, including in Brazil. This study aimed to conduct a gap analysis and identify priority areas for seahorse

The Ulva spp. Conundrum: What Does the Ecophysiology of Southern Atlantic Specimens Tell Us?

Journal of Marine Sciences, Volume 2019, Issue 1, 2019., 2019
Species of the genus Ulva are common in anthropogenically disturbed areas and have been reported as the cause of green tides in many areas of the world. In addition, they rank among the main marine groups used in a wide range of commercial applications.

Multibiomarker Approach in Fish to Assess a Heavily Polluted Brazilian Estuary, Guanabara Bay

Environmental Monitoring and Assessment, 2022
Abstract Brazil’s Guanabara Bay (GB), located in Rio De Janeiro, is a deeply contaminated, eutrophic waterbody that has a reduced environment that challenges the understanding of the effects of pollutants on the biota. This paper presents an integrated strategy to evaluate the impact of contamination, utilizing a multibiomarker approach in the ...

BioTIME 2.0: Expanding and Improving a Database of Biodiversity Time Series

Global Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Motivation Here, we make available a second version of the BioTIME database, which compiles records of abundance estimates for species in sample events of ecological assemblages through time. The updated version expands version 1.0 of the database by doubling the number of studies and includes substantial additional curation to the taxonomic ...

A strong CO₂ sink enhanced by eutrophication in a tropical coastal embayment (Guanabara Bay, Rio de Janeiro, Brazil) [PDF]

Biogeosciences, 2015
In contrast to its small surface area, the coastal zone plays a disproportionate role in the global carbon cycle. Carbon production, transformation, emission and burial rates at the land–ocean interface are significant at the global scale but still ...

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

Marine 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.

Update of the risk assessment of brominated phenols and their derivatives in food

EFSA Journal, Volume 22, Issue 10, October 2024.
Abstract The European Commission asked EFSA to update its 2012 risk assessment on brominated phenols and their derivatives in food, focusing on five bromophenols and one derivative: 2,4,6‐tribromophenol (2,4,6‐TBP), 2,4‐dibromophenol (2,4‐DBP), 4‐bromophenol (4‐BP), 2,6‐dibromophenol (2,6‐DBP), tetrabrominated bisphenol S (TBBPS), tetrabromobisphenol S

Integrating multiple lines of evidence of sediment quality in a tropical bay (Guanabara Bay, Brazil)

Marine Pollution Bulletin, 2019
The present study evaluated the ecological risk of metal contamination in sediments of Guanabara Bay (GB) by combining multiple lines of evidence (LOEs). Chemical analysis and a set of whole-sediment toxicity assays were conducted with Tiburonella viscana, Kalliapseudes schubartii, Anomalocardia flexuosa, and Nitocra sp.
