High rDNA polymorphisms in Astyanax lacustris (Characiformes: Characidae): new insights about the cryptic diversity in A. bimaculatus species complex with emphasis on the Paraná River basin

Neotropical Ichthyology, 2022
This study aimed to identify species of Astyanax bimaculatus group from four Itaipu Reservoir tributaries (Paraná River Basin) by cytogenetics and molecular markers (COI) to investigate the possible occurrence of cryptic diversity in part of this basin ...

Insect meals in fish nutrition

Reviews in Aquaculture, Volume 11, Issue 4, Page 1080-1103, November 2019., 2019
Abstract Different studies have shown that insect meals can partially or completely replace the fish and soya bean meals that are commonly used in aquaculture. However, information is lacking on the amino acid and fatty acid contents and digestibility of different insect meals. Moreover, we evaluated different proportions of insect diets and determined

Inducción de micronúcleos y otras anormalidades nucleares en Astyanax gr. bimaculatus (Pisces: Characidae) expuestas a fenantreno

, 2012
Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) associated with the oil industry, highly lipophilic, ubiquitous and with the property to persist in the environment for longer periods. Despite its impact, few studies has been carry out in tropical

Trends in Medicinal Uses of Edible Wild Vertebrates in Brazil

Evidence-Based Complementary and Alternative Medicine, Volume 2017, Issue 1, 2017., 2017
The use of food medicines is a widespread practice worldwide. In Brazil, such use is often associated with wild animals, mostly focusing on vertebrate species. Here we assessed taxonomic and ecological trends in traditional uses of wild edible vertebrates in the country, through an extensive ethnobiological database analysis. Our results showed that at

Restoration Effects of the Riparian Forest on the Intertidal Fish Fauna in an Urban Area of the Amazon River

The Scientific World Journal, Volume 2016, Issue 1, 2016., 2016
Urbanization causes environmental impacts that threaten the health of aquatic communities and alter their recovery patterns. In this study, we evaluated the diversity of intertidal fish in six areas affected by urbanization (areas with native vegetation, deforested areas, and areas in process of restoration of vegetation) along an urban waterfront in ...

Using Gap Visualization to Navigate Multivariate Metabarcode Data, Select Primer Pairs, and Enhance Reference Data Quality

Environmental DNA, Volume 6, Issue 6, November–December 2024.
We introduce the metabarcoding gap visualization and demonstrated how it can make comparisons of PCR primers rapidly comprehensible for researchers in the molecular ecology community. We use gap visualization to simultaneously interrogate multiple primer pairs and enhance reference data quality. This has significant impact for study design as selecting
