Trace elements assessment in Cerastoderma glaucum from port areas in the Tunisi...

In the present study, the seasonal concentration of seven trace elements was investigated in sediment and the cockle Cerastoderma glaucum tissues from two port areas in the North-East and South of Tunisia comparing cockles non-parasitized (NP) and parasitized (P) with digenean parasites. Elements concentration in sediments analyzed in both sites revealed that Zinc (Zn), Chromium (Cr), and Lead (Pb) were the mos...

Morphological vs. molecular identification of trematode species infecting the e...

Identifying marine trematode parasites in host tissue can be complicated when there is limited morphological differentiation between species infecting the same host species. This poses a challenge for regular surveys of the parasite communities in species of socio-economic and ecological importance. Our study focused on identifying digenean trematode species infecting the marine bivalve Cerastoderma edule acros...

Do Freshwater and Marine Bivalves Differ in Their Response to Wildfire Ash? Eff...

Wildfires constitute a source of contamination to both freshwater and marine ecosystems. This study aimed to compare the antioxidant defense response of the freshwater clam Corbicula fluminea and the marine cockle (Cerastoderma edule) to wildfire ash exposure and the concomitant metal body burden. Organisms were exposed to different concentrations (0%, 12.5%, 25%, 50%, and 100%) of aqueous extracts of Eucalypt ...

Ativação de Marca junto da Geração Z

The sense of differentiation, notoriety and belonging is increasingly important on the part of consumers. In this article, aspects such as the concept of generation Z, brand activation and GPT chat, but also, how to be innovative in the eyes of this generation are covered. The big unknown is how the impact of these new technologies can influence this new brand activation and this generation, who is known to be ...

Effects of cockle density and environmental background in the structure of free...

Biotic and abiotic factors can play an important role in the parasite community. The likelihood of successful parasite transmission rises with host density. At the same time, high host density can provide a dilution effect that lessens the host’s individual burden. In this study, the effects of cockle (Cerastoderma edule) density and environmental factors in the structure of free-living and parasitic communitie...

Effect of the alveolate parasite Perkinsus olseni infection on sexual maturatio...

The effect of Perkinsus olseni infection on the reproduction ability of clams has been underestimated so far. Although some studies found evidence of reduction of egg production and delay in gonad maturation after infection, the total effect of the infection is still unclear. In this study, Ruditapes decussatus clams from a naïve population were injected with two different doses of P. olseni parasites, a low do...

Trematode genetic patterns at host individual and population scales provide ins...

Multiple parasites can infect a single host, creating a dynamic environment where each parasite must compete over host resources. Such interactions can cause greater harm to the host than single infections and can also have negative consequences for the parasites themselves. In their first intermediate hosts, trematodes multiply asexually and can eventually reach up to 20% of the host's biomass. In most species...
