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 ...

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 ...

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 ...

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 ...

A context analysis of bobbing and fin‐flicking in a small marine benthic fish
Ecology and Evolution, Volume 11, Issue 3, Page 1254-1263, February 2021., 2021 In fish, repeatedly and rapidly raising and lowering the anterior part of the body (bobbing) and repeated flicks of the dorsal, pectoral, or pelvic fins (fin‐flicking) are common behaviors often studied in the context of predation. We show that such behavioral traits can have other than an antipredator function in small marine triplefins.

Informative and misinformative interactions in a school of fish [PDF]
, 2017 It is generally accepted that, when moving in groups, animals process information to coordinate their motion. Recent studies have begun to apply rigorous methods based on Information Theory to quantify such distributed computation.
