Spatio-temporal variation of trematode parasites community in Cerastoderma edule cockles
from Ria de Aveiro (Portugal)

Authors: Luísa Magalhães, Simão Correia, Xavier de Montaudouin, Rosa Freitas

Description: A spatio-temporal monitoring of cockles from Ria de Aveiro (Portugal) was performed. The results showed that trematode parasites community infecting cockles can be used to characterize the environment with respective assessment of the ecosystem ecological status and possible identification of threatened areas (specifically in terms of biodiversity and environmental conditions).

Trematode infection modulates cockles biochemical response to climate change

Authors: Luísa Magalhães, Xavier de Montaudouin, Etelvina Figueira, Rosa Freitas

Description: Following an experimental approach, it was demonstrated that when exposed to climate change related factors (water acidification and warming), cockles presented higher infection rate and weak biochemical performance. This study highlighted the negative impact of forecasted changes in cockles, which may promote the proliferation of parasites with influence on the geographical distribution of some diseases.

Non-indigenous species in soft-sediments: Are some estuaries more invaded than others?

Authors: Sara Cabral, Frederico Carvalho, Miguel Gaspar, João Ramajal, Erica Sá, Cátia Santos, Gilda Silva, António Sousa, José Lino Costa, Paula Chainho

Description: Non-indigenous species (NIS) were studied in the Tagus and Sado estuaries (Portugal), providing a baseline list of occurrences with indication of relative abundance. NIS represented 1/4 of total species found, highlighting the threat to native populations sustainability (including cockles).

Interactive effects of contamination and trematode infection in cockles biochemical performance

Authors: Luísa Magalhães, Xavier de Montaudouin, Etelvina Figueira, Rosa Freitas

Description: Following an experimental approach, this study showed the harmful effects of trematode parasites in cockles individual health and highlighted the importance to include parasitology in ecotoxicological studies to avoid incorrect identification of some marine species as tolerant or susceptible to a given stress, when in fact the physiological response of the organism is modified by a parasitic infection.

A Useful SNP Panel to Distinguish Two Cockle Species, 'Cerastoderma edule' and 'C. glaucum', Co-Occurring in Some European Beds, and Their Putative Hybrids

Authors: Francesco Maroso, Celia Pérez de Gracia, David Iglesias, Asunción Cao, Seila Díaz, Antonio Villalba, Manuel Vera, and Paulino Martínez

Description: For the first time, a panel of SNPs (single nucleotide polymorphisms) was identified to distinguish cockles Cerastoderma edule from C. glaucum, co-occurring in some European beds, a valuable tool for management purposes.

Temporal dynamics of infection of cockles 'Cerastoderma edule' with the protistan parasite 'Minchinia tapetis' (Rhizaria: Haplosporida) in Galicia (NW Spain)

Authors: María J. Carballal, Assunción Cao, David Iglesias, Ana I. González, Antonio Villalba

Description: A new occurrence of Minchinia tapetis (Rhizaria: Haplosporidia) was detected in cockles from Ría de Noia (Galicia, Spain) with high prevalence but low to moderate intensity. The positive correlation found between this parasite prevalence and water temperature, classified this parasite species as a possible production threat in actual and predicted climate change scenarios.

Ecosystem services provided by a non-cultured shellfish species: The common cockle 'Cerastoderma edule'

Authors: David N. Carss, Ana C. Brito, Paula Chainho, Aurélie Ciutat, Xavier de Montaudouin, Rosa M. Fernández Otero, Mónica Incera Filgueira, Angus Garbutt, M. Anouk Goedknegt, Sharon A. Lynch, Kate E. Mahony, Olivier Maire, Shelagh K. Malham, Francis Orvain, ...

Description: A full assessment of ecosystems services provided by cockles was presented reporting for 5 European countries from the Atlantic coast (UK, Ireland, France, Spain and Portugal). This work highlighted the potential of cockles to be an important focus of conservation and management actions and to be a model to study the integration of cultural ecosystems services in the ecosystem services broader framework.

'Monorchis parvus' and 'Gymnophallus choledochus': two trematode species infecting cockles as first and second intermediate host

Authors: Luísa Magalhães, Guillemine Daffe, Rosa Freitas, Xavier de Montaudouin

Description: A literature review was performed to depict infection patterns of two trematode species using cockles as host. It was showed that different parasite species display different size range preferences and that coinfection is rare, raising some questions about interspecific competition. It was highlighted the need to identify main predictors of infection towards better management of severe disease and mortality events.

Fine-scale seascape genomics of an exploited marine species, the common cockle 'Cerastoderma edule', using a multi modelling approach

Authors: Ilaria Coscia, Sophie B. Wilmes, Joseph E. Ironside, Alice Goward-Brown, Enda O’Dea, Shelagh K. Malham, Allan D. McDevitt, Peter E. Robins

Description: The study of fine-scale spatial genetic structure of cockles was combined to a multi modelling approach towards identification of genetic clusters in the north-west Atlantic Area. The results filled an important knowledge gap, bringing insights concerning the role of larval dispersal in population connectivity

Does parasitism influence sediment stability? Evaluation of trait-mediated effects of the trematode 'Bucephalus minimus' on the key role of cockles 'Cerastoderma edule' in sediment erosion dynamics

Authors: Annabelle Dairain, Olivier Maire, Guillaume Meynard, Francis Orvain

Description: This study confirmed the influence of cockles in the sediment dynamics and stability (= ecosystem engineers) and was pioneer in the study of indirect influence of parasitism on sediment dynamics processes. It was demonstrated that when parasitized, cockles had a different influence on the sediment dynamics with impact in the microphytobenthos growth.

Large scale patterns of trematode parasite communities infecting 'Cerastoderma edule' along the Atlantic coast from Portugal to Morocco

Authors: Simão Correia, Luísa Magalhães, Rosa Freitas, Hocein Bazairi, Meriam Gam, Xavier de Montaudouin

Description: A spatial monitoring of cockles from Portugal to Morocco was performed to analyse trematode community patterns. The results showed that more important than latitude and besides host presence, the temperature is an important trigger of parasite infection with coastal upwelling operating as a shield against trematode infection in Portugal.

Parasite Assemblages in a Bivalve Host Associated with Changes in Hydrodynamics

Authors: Simão Correia, Ana Picado, Xavier de Montaudouin, Rosa Freitas, Rui Rocha, João Dias, Luísa Magalhães

Description: Following a spatio-temporal monitoring of cockles from Ria de Aveiro (Portugal) and an experimental approach, it was demonstrated that cockles collected intertidally and exposed to higher water current velocities showed higher infection rates than subtidal cockles or exposed to lower current velocity. This study highlighted the importance of host vertical and horizontal position on trematode infection, highlighting the positive influence of current velocity by supporting trematode settlement and favourable abiotic conditions.
