CONDITION FACTOR AND ECOLOGY OF ENDOHELMINTHS IN Metynnis lippincottianus FROM THE CURIAÚ RIVER, IN EASTERN AMAZON (BRAZIL)

open access: yesBoletim do Instituto de Pesca, 2020
Fish are among the vertebrate groups most susceptible to parasitic infections due to environmental characteristics that can favor the development of parasites; also, position of the host in food web has been associated with the parasitism.

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork

open access: yesFreshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Metagenomic Insights Into the Dietary Diversity of the Adaptive Radiation of Cichlid Fishes in Lake Tanganyika

open access: yesMolecular Ecology, Volume 34, Issue 9, May 2025.
ABSTRACT Diet specialisation is a main driver of diversification in many adaptive radiations. Therefore, identifying diet items is essential to characterise trophic specialisations and to understand the dynamics of dietary adaptations. In this study, we explored the trophic niches of 56 species from the adaptive radiation of cichlid fishes in Lake ...

The Ribosomal Operon Database: A Full‐Length rDNA Operon Database Derived From Genome Assemblies

open access: yesMolecular Ecology Resources, Volume 25, Issue 1, January 2025.
ABSTRACT Current rDNA reference sequence databases are tailored towards shorter DNA markers, such as parts of the 16/18S marker or the internally transcribed spacer (ITS) region. However, due to advances in long‐read DNA sequencing technologies, longer stretches of the rDNA operon are increasingly used in environmental sequencing studies to increase ...
