A new species of Hemigrammus Gill, 1858 (Characiformes: Characidae) from the rio Madeira and rio Paraguai basins, with a redescription of H. lunatus [PDF]
Neotropical Ichthyology, 2020 A new Hemigrammusis described from the rio Paraguai and rio Madeira basins, Mato Grosso and Rondônia States, Brazil. The new species is characterized by possessing a wide dark horizontal stripe across the eye, a vertically elongated humeral blotch, and 4-

Species-specific behaviour and environmental drivers of trap interactions in wild ornamental fishes. [PDF]
J Fish BiolAbstract The harvest of animals from the wild is a pervasive selective force, especially in fisheries, where harvesting often targets individuals with specific traits. While most research has focused on large‐scale commercial or recreational fisheries, little attention has been paid to artisanal fisheries, particularly those targeting ornamental ...

Characterization of Mitochondrial Genomes and Evolutionary Relationships in Two <i>Moenkhausia</i> (Characiformes: Acestrorhamphidae). [PDF]
Ecol EvolThis study successfully decoded the complete mitochondrial genomes of two Moenkhausia species, with total lengths of 16,439 and 16,461 bp, respectively. This study enhances genomic resources for Acestrorhamphidae and provides a foundation for investigating evolutionary mechanisms and developing molecular markers.

Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River. [PDF]
Conserv BiolAbstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

Mechanisms of group‐hunting in vertebrates
Biological Reviews, Volume 98, Issue 5, Page 1687-1711, October 2023., 2023 ABSTRACT Group‐hunting is ubiquitous across animal taxa and has received considerable attention in the context of its functions. By contrast much less is known about the mechanisms by which grouping predators hunt their prey. This is primarily due to a lack of experimental manipulation alongside logistical difficulties quantifying the behaviour of ...

Conformity in mate choice, the overlooked social component of animal and human culture
Biological Reviews, Volume 98, Issue 1, Page 132-149, February 2023., 2023 ABSTRACT Although conformity as a major driver for human cultural evolution is a well‐accepted and intensely studied phenomenon, its importance for non‐human animal culture has been largely overlooked until recently. This limited for decades the possibility of studying the roots of human culture.

Mitochondrial genomes of five Hyphessobrycon tetras and their phylogenetic implications
Ecology and Evolution, Volume 11, Issue 18, Page 12754-12764, September 2021., 2021 To date, the taxonomic status and phylogenetic affinities within Hyphessobrycon, even among other genera in Characidae, remains unclear. Here, we determined five new mitochondrial genomes of Hyphessobrycon species. Abstract To date, the taxonomic status and phylogenetic affinities within Hyphessobrycon, even among other genera in Characidae, remain ...

Environmental DNA, Volume 3, Issue 5, Page 889-900, September 2021., 2021 A multi‐marker scat DNA metabarcoding approach was used to examine the dietary diversity of the world's largest and rarest otter, the iconic giant otter (Pteronura brasiliensis) from fecal DNA. The combined use of highly discriminant markers (COI and 12S) and of local reference databases of DNA barcodes offered a high accuracy of taxonomic assignments ...
