Hydrological Connectivity Enhances Fish Biodiversity in Amazonian Mining Ponds: Insights From eDNA and Traditional Sampling. [PDF]
Mol EcolABSTRACT Artisanal and small‐scale gold mining (ASGM) expansion in the Madre de Dios region of the Peruvian Amazon has transformed primary forests into a novel wetland complex of thousands of abandoned mining ponds. Despite their ecological relevance, post‐mining recovery of these systems remains understudied, particularly regarding fish biodiversity ...

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 ...

Phylogenetic relationships of the neon tetras Paracheirodon spp. (Characiformes: Characidae: Stethaprioninae), including comments on Petitella georgiae and Hemigrammus bleheri [PDF]
Neotropical Ichthyology, 2020 Neon tetras (Paracheirodon spp.) are three colorful characid species with a complicated taxonomic history, and relationships among the species are poorly known. Molecular data resolved the relationships among the three neon tetras, and strongly supported

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 ...
