Comparative cytogenetics in Astyanax (Characiformes: Characidae) with focus on the cytotaxonomy of the group [PDF]
Neotropical Ichthyology, 2013 Astyanax is a diverse group of Neotropical fishes, whose different forms occupy different environments. This great diversity is also reflected on cytogenetic aspects and molecular markers, which have repeatedly been demonstrated by cytogenetic studies ...

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 ...

Competition from sea to mountain: Interactions and aggregation in low-diversity monogenean and endohelminth communities in twospot livebearer Pseudoxiphophorus bimaculatus (Teleostei: Poeciliidae) populations in a neotropical river. [PDF]
Ecol Evol, 2020 The results of this work suggest that interspecific competition can occur in species‐poor, nonsaturated communities among specialist dominant species. Our analyses suggest also that aggregation is an important factor to determine local richness of parasites in fish populations and that intraspecific aggregation allows the coexistence of species in the ...

Evolution &Development, Volume 25, Issue 2, Page 170-193, March 2023., 2023 Lake Malawi cichlids harbor a spectacular intra‐ and interspecific morphological diversity yet understanding of how early in ontogeny species‐specific phenotypes emerge remains limited. A comparative analysis of early development of three divergent Malawi cichlids reveals anatomical and timing differences during embryogenesis and indicates divergence ...

Aquaculture, Fish and Fisheries, Volume 2, Issue 4, Page 277-286, August 2022., 2022 A 90‐day aquarium trial was conducted to evaluate the effect of temperature on the growth, blood chemistry and histology of vital organs in juvenile Ompok bimaculatus. Fish reared at 30℃ showed significantly higher growth performances, specific growth rate and haemoglobin and white blood cell counts in comparison to the control group at 25℃. Fish at 30℃
