Bivalve molluscs stand out for their ecological success and key role in the functioning of aquatic ecosystems, while also constituting a very valuable commercial resource. Both production bivalves depend on effective immune defence function, which haemocytes play central acting as both undertaker cellular immunity supplier humoral immunity. Bivalves have different types haemocytes, perform functions. Hence, identification cell subpopulations functional characterisation responses is essential to fully understand system bivalves. Nowadays, there not unified nomenclature that applies all Characterisation bivalve haemocyte often combined with 1) other multiple parameter assays determine differences between immune-related physiological activities, such phagocytosis, oxidative stress apoptosis; 2) response stressors pathogens, temperature, acidification pollution. This review summarises major most recent findings classification main molluscs.

Organisms face energetic challenges of climate change in combination with suites natural and anthropogenic stressors. In particular, chemical contaminant exposure has neurotoxic, endocrine-disrupting, behavioral effects which may additively or interactively combine associated change. We used a literature review across animal taxa classes, but focused on Arctic endotherms contaminants important ecosystems, to demonstrate potential for interactive five bioenergetic domains: (1) energy supply, (2) demand, (3) storage, (4) allocation tradeoffs, (5) management strategies; involving four change-sensitive environmental stressors: changes resource availability, temperature, predation risk, parasitism. Identified examples included relatively equal numbers synergistic antagonistic interactions. Synergies are often suggested be particularly problematic, since they magnify biological effects. However, we emphasize that traits can equally reflect dampening beneficial responses result negative fitness. Our also highlights empirical demonstrations remain limited, especially endotherms. Elucidating the nature change-by-contaminant will build toward determining overall outcomes balance Progressing determine critical species, life stages, target areas transformative arise aid forecasting broad-scale under global scenarios.

Trematode parasites are distributed worldwide and can severely impact host populations. However, their influence on ecosystem functioning through the alteration of engineering behaviours remains largely unexplored. This study focuses a common parasite system in marine coastal environments, i.e., trematode Himasthla elongata, infecting edible cockle Cerastoderma edule as second intermediate host. A laboratory experiment was conducted to investigate indirect effects metacercarial infection sediment bioturbation biogeochemical fluxes at water interface. Our results revealed that, despite high intensity, reworking bioirrigation rates, well nutrient fluxes, were not impacted. finding unexpected since previous studies showed that impairs physiological condition cockles induces mechanical obstruction feet, thus altering burrowing capacity. There several explanations for such contrasting results. Firstly, behavior could arise over longer time period following infection. Secondly, modulation by be more pronounced older specimens burying deeper. Thirdly, intensity deleterious impacts metacercariae strongly vary across species. Lastly, alters fitness an interaction with other biotic abiotic environmental stressors.

Abstract Trematodes are the main macroparasites in coastal waters. The most abundant and widespread form of these parasites is metacercaria. Their impact on their host fitness considered relatively low but metacercarial larvae some species can have deleterious effects individuals and/or populations. This review focused cockle Cerastoderma edule four genus Himasthla ; a common host–parasite system marine environments. Our aims were (1) to literature concerning continua , elongata interrupta quissetensis cockles; (2) provide molecular signatures (3) analyse infection patterns using 20-year monthly database monitoring from Banc d'Arguin (France). Due identification uncertainties, analysis was restricted H. it revealed that infect cockles same size range. intensity increased with size/age. During colder months, mean parasite cohort decreased, while occurred warmest season. No inter-specific competition between trematode detected. Furthermore, even if or fluctuated different years, this did not modify community structure cockles. both also positively correlated richness abundance. study highlighted possible detrimental role spp. population dynamics. It risks misidentification, which should be resolved by further approaches.

Bivalve populations are prone to change due sudden or gradual alteration in the natural environment and anthropogenic interference. Fisheries environmental managers therefore interested long-term trends disentangling human influences, assisting them conservation efforts management of bivalve stocks. Here, 64 monitoring reports covering a 50-year period from 1958 2009 cockles Cerastoderma edule (Linnaeus, 1758) South Wales, UK, were scrutinised for data on recruitment, growth mortality. Changes these population parameters related modernisation wastewater treatment 1997, weather climate variables (temperature, sun hours, air frost days, NAO) numbers estuary. Recruitment as well mortalities high during first last decade study, variation was significantly linked total number population. Cockle sizes all cohorts overall biomass declined late 1990s. Modernisation with downward trend, suggesting that changed nutrient regime estuary may have resulted reduced food provision cockles. The average size newly settled their mortality: smaller recruits higher study indicated link between 1997 diminishing cockle shortened life span. Survey methods profoundly after 2009, it is recommended develop conversion factors pre- post-2009 survey methods. This would allow an extension timeline deeper insight into impact recovery

In the population dynamics of bi-phasic marine invertebrates, fitness one stage in life a cohort affects that following stage. This effect makes prediction fate challenging. We conducted 22 yr monthly survey cockles Cerastoderma edule focussed on juvenile Two types years were distinguished terms longevity: low-mortality group (‘L’) and high-mortality (‘H’). The cockle shell lengths 0 + cohorts was higher L group, August September. A could hereby confidently be assigned to or H as soon August. Maximum abundance cohorts, parasite load, date recruitment did not discriminate groups, while an early for peak related group. maximum air temperature chl concentration July whereas minimum salinity during month September slightly lower years. Therefore, length under given threshold identified alert short lifespan cohort. long-term analysis contributes deeper understanding invertebrates. success juveniles is solely intensity mortality by predation, but also linked their fitness, growth rates appearing proxy.
