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 ...

The taxonomic status of Farlowella colombiensis Retzer & Page 1997 with comments on species of the F. acus species group (Loricariidae: Loricariinae). [PDF]
J Fish BiolAbstract The genus Farlowella has been historically challenging, in part due to the difficulty in defining diagnostic characters for defining and identifying the species. Farlowella colombiensis is one such example, whose diagnostic characters are based on caudal‐fin colour pattern, ventral pattern of body cover and anatomical details of the head, such

Fish Diversity and Environmental Relationships in the Jinsha River During the Initial Phases of the 10-Year Fishing Ban: A Metabarcoding Approach. [PDF]
Ecol EvolUsing eDNA metabarcoding, we identified 61 fish species in the Jinsha river during the early stage of the Yangtze river fishing ban. Fish diversity showed seasonal and regional variation, with Cypriniformes as the dominant group. Key environmental factors like temperature and dissolved oxygen were closely linked to diversity patterns.

Phylogenetic analysis of microbial communities in different regions of the gastrointestinal tract in Panaque nigrolineatus, a wood-eating fish [PDF]
, 2012 The Neotropical detritivorous catfish Panaque nigrolineatus imbibes large quantities of wood as part of its diet. Due to the interest in cellulose, hemi-cellulose and lignin degradation pathways, this organism provides an interesting model system for the

Examination of a culturable microbial population from the gastrointestinal tract of the wood-eating loricariid catfish Panaque nigrolineatus [PDF]
, 2013 Fish play a critical role in nutrient cycling and organic matter flow in aquatic environments. However, little is known about the microbial diversity within the gastrointestinal tracts that may be essential in these degradation activities.

Environmental DNA Reveals the Fish Community Structure Exhibited Instability and Trend of Miniaturization in the Xijiang River Basin of the Guizhou. [PDF]
Ecol EvolMonitoring of fish communities is of great significance for the management and sustainability of river ecosystems. Environmental DNA (eDNA) metabarcoding technology has been demonstrated to be a highly sensitive biomonitoring tool. Nevertheless, it has seldom been tested in mountainous rivers within the geographically complex Karst region.
