Why ignoring parasites in fish ecology is a mistake
(Elsevier, 2020-09)
Parasites are ubiquitous components of biological systems that have evolved in multiple independent lineages during the history of life, resulting in a diversity of taxa greater than that of their free-living counterparts. ...
Seasonality of parasitic helminths of Leporinus macrocephalus and their parasitism rates in farming systems in the Amazon
(Colégio Brasileiro de Parasitologia Veterinária, 2018)
Experimental evidence that host choice by parasites is age-dependent in a fish-monogenean system
(2022-01-01)
Host age is known to influence the risk of parasite infection, but there is very little experimental evidence on whether parasites show preference towards potential hosts of a specific age. To investigate how host age ...

Brazilian catfish parasitized by Epistylis sp. (Ciliophora, Epistylididae), with description of parasite intensity score
(2013-01-01)
The determination of mean intensity of parasitism for colony-forming sessile protozoan such as Epistylis has been a great problem in parasitological studies. Some alternatives have been proposed by researchers for laboratory ...
