Experimental Evidence of Differences in Life History Characteristics and Interactions Between Cryptic Species of Diplostomum (Digenea) [PDF]

open access: yes, 2018
Recent DNA studies have uncovered diversity in sympatric species of Diplostomum (Digenea), a cosmopolitan parasite with a three host life-cycle infecting a piscivorous bird, snail and fish at different stages during its life cycle.

The role of parasite diversity in the life of the three-spined sticklebacks [PDF]

open access: yes, 2006
Parasite infections containing genetically different parasites of the same species are widespread in nature. The genetic diversity is predicted to influence parasite load, the evolution of virulence and host defence mechanisms. According to kin-selection

In-feed Praziquantel treatment of grass carp (Ctenopharyngodon idella) infected with eye flukes

open access: yesVeterinární Medicína
Praziquantel (PZQ) is a drug effective against several parasitic diseases of fish caused by Platyhelminthes. The study assesses the efficacy of selected in-feed PZQ doses in eliminating metacercariae Diplostomum pseudospathaceum in grass carp.

Parasite avoidance behaviours in aquatic environments [PDF]

open access: yes, 2018
Parasites, including macroparasites, protists, fungi, bacteria and viruses, can impose a heavy burden upon host animals. However, hosts are not without defences. One aspect of host defence, behavioural avoidance, has been studied in the terrestrial realm

Ecological and host behavioural aspects of parasite dispersal in a simple and a complex host–parasite system [PDF]

open access: yes
If one is to understand how parasitic diseases spread within and among host populations, one has to take into account characteristics of the given parasite species, the host as well as of their common environment.

Molecular basis of ecological speciation in sticklebacks [PDF]

open access: yes, 2018
The constant race to outcompete other organisms, either from the same or another species drives the continuous emergence of new and, better-adapted individuals.
