Early Biogeography of Otophysi Points to the Neotropics as the Cradle of Characiphysan Fishes Open
Freshwaters represent less than 1% of Earth's surface and only 0.02% of the available aquatic habitable volume, yet they host nearly half of the 35,500 known species of bony fishes. Ostariophysan fishes account for 70% of all freshwater fi…
Quantifying the success of prey crypsis, aposematism, and evasiveness in avoiding predator attack Open
Antipredator defenses typically act at distinct stages of the predation sequence—encounter, identification, approach, and subjugation. However, their effectiveness has rarely been quantified and compared simultaneously in wild predator–pre…
The Complete Chloroplast Genome of Tornillo (<i>Cedrelinga cateniformis</i> Ducke 1922, Fabaceae) Open
Tornillo ( Cedrelinga cateniformis Ducke 1922) is a tropical tree of the Fabaceae family. It is commonly used in the lumber factory and is an interesting substitute to overexploited tropical timber species. We sequenced and assembled the f…
Quantifying the success of prey crypsis, aposematism and evasiveness in avoiding predators’ attack Open
Antipredator defences typically act at distinct stages of the predation sequence—encounter, identification, approach, and subjugation. However, their effectiveness has rarely been quantified and compared simultaneously in wild predator-pre…

Quantitative impacts of hydroelectric dams on the trans‐Amazonian migrations of goliath catfish Open
Hydropower expansion is increasingly responsible for connectivity and biodiversity loss in freshwater ecosystems. The Amazon basin, which supports the highest level of freshwater biodiversity globally, faces such unplanned expansion. Here,…

Timber Tracking of Jacaranda copaia from the Amazon Forest Using DNA Fingerprinting Open
We investigated the utility of nuclear and cytoplasmic single nucleotide polymorphism (SNP) markers for timber tracking of the intensively logged and commercialized Amazonian tree Jacaranda copaia. Eight hundred and thirty-two trees were s…
Expanding the Distribution and Phylogenetic Insights of <i>Chrysobrycon mojicai</i> in the Peruvian Amazon: Morphological and Molecular Analyses with Taxonomic Corrections Open
This study focuses on the genus Chrysobrycon , particularly Chrysobrycon mojicai , which was initially described in the Amacayacu National Natural Park in Colombia. Here, we document a new geographical record of C. mojicai in various locat…
The complete chloroplast genome of Marupa (<i>Simarouba amara</i> Aubl., Simaroubaceae) Open
Marupa ( Simarouba amara Aublet 1775) is a tropical tree of the family Simaroubaceae. It is commonly used for its wood in the Amazonian forest, and it is an important species for restoring degraded environments. Yet, very little genetic re…
Timber tracking of Jacaranda copaia from Amazon Forest using DNA fingerprint Open
Amazon tropical forest is actually subject to strong deforestation, generally originated from illegal logging, resulting in ecological, environmental and economic problems. Aiming stop deforestation and timber commercialization of illegal …
Unveiling biogeographical patterns of the ichthyofauna in the Tuichi basin, a biodiversity hotspot in the Bolivian Amazon, using environmental DNA Open
To date, more than 2400 valid fish species have been recorded in the Amazon basin. However, some regions remain poorly documented. This is the case in the Beni basin and in particular in one of its main sub-basins, the Tuichi, an Andean fo…
Age validation and contrasted growth performances of Pseudoplatystoma punctifer (Siluriformes: Pimelodidae) in two river systems of the Western Amazon Open
The doncella Pseudoplatystoma punctifer is an economically and ecologically important catfish in the Amazon basin. However, little is known about its age, growth and population dynamics parameters. This study aims to validate the formation…

The Silent Threat of Non-native Fish in the Amazon: ANNF Database and Review Open
Non-native fish (NNF) can threaten megadiverse aquatic ecosystems throughout the planet, but limited information is available for the Amazon Region. In this study we review NNF data in the Amazonian macroregion using spatiotemporal records…
Species‐level ichthyoplankton dynamics for 97 fishes in two major river basins of the Amazon using quantitative metabarcoding Open
The Amazon basin holds the world's largest freshwater fish diversity. Information on the intensity and timing of reproductive ecology of Amazonian fish is scant. We use a metabarcoding method by capture using a single probe to quantify spe…

Conservation of migratory fishes in the Amazon basin Open
The Amazon basin hosts the Earth's highest diversity of freshwater fish. Fish species have adapted to the basin's size and seasonal dynamics by displaying a broad range of migratory behaviour, but they are under increasing threats; however…

The Digestive Function of Pseudoplatystoma punctifer Early Juveniles Is Differentially Modulated by Dietary Protein, Lipid and Carbohydrate Content and Their Ratios Open
Pseudoplatystoma punctifer is an Amazonian catfish highly appreciated for its high flesh quality, size, and commercial value. Its aquaculture is pursued to satisfy the demands of an increasing population in the region. However, knowledge o…
Isolation, identification, and gene expression analysis of the main digestive enzymes during ontogeny of the Neotropical catfish Pseudoplatystoma punctifer (Castelnau, 1855) Open
The ontogeny of the digestive capacities in fish is species-specific and its knowledge is essential for understanding the nutritional requirements of fish larvae. While the Amazon basin contains the world's highest fish biodiversity, the m…
Threatened fish spawning area revealed by specific metabarcoding identification of eggs and larvae in the Beni River, upper Amazon Open
Identifying fish spawning areas is of great ecological and conservation importance as fishes are suffering increasing threats levels from anthropogenic activities. However, to date very few studies have done so in the Amazon basin. In the …
The Amazonian dwarf cichlid <span><i>Apistogramma agassizii</i></span> (Steindachner, 1875) is a geographic mosaic of potentially tens of species: Conservation implications Open
Assessing biodiversity and understanding how it works is a prerequisite for species conservation. The Amazon basin is one of the main biodiversity hotspots where fish are heavily exploited for ornamental purposes. The ornamental trade heav…
