Assessment of seabed litter at Concepción Seamount (Canary island) using a remotely operated towed vehicle.

The seafloor is recognised as a major sink for marine litter. However, studies conducted in this compartment addressing marine litter densities and its interactions with fauna are scarce, mainly due to sampling constraints. In this paper, we assess marine litter density, composition and interactions with marine communities and evaluate its relationship with fishing activities at the "Banco de la Concepción" seamount (Canary Islands, Spain).

A common garden experiment supports a genetic component underlying the increased resilience of common cockle () to the parasite .

The common cockle is a valuable bivalve species inhabiting the Atlantic European coasts. The parasite has devastated cockle beds in the southern Galician (NW Spain) rias since 2012. Previous data suggested that cockles from Ría de Arousa acquired some resilience to this parasite through natural selection after consecutive annual marteiliosis outbreaks and candidate markers associated with marteiliosis resilience were identified using population genomics and transcriptomics approaches.

A nationwide monitoring of atmospheric microplastic deposition.

Plastic production continues to increase every year, yet it is widely acknowledged that a significant portion of this material ends up in ecosystems as microplastics (MPs). Among all the environmental compartments affected by MPs, the atmosphere remains the least well-known. Here, we conducted a one-year simultaneous monitoring of atmospheric MPs deposition in ten urban areas, each with different population sizes, economic activities, and climates.

Invasion of Sargassum muticum in intertidal rockpools: patterns along the Atlantic Iberian Peninsula.

Spatial patterns of non-indigenous species show scale-dependent properties. Sargassum muticum is an invasive macroalga widely distributed along the Atlantic Iberian Peninsula. Despite being quite abundant from Norway to South Portugal, there is little information about its patterns of distribution, particularly at a large spatial scale (i.

Limited impact of Sargassum muticum on native algal assemblages from rocky intertidal shores.

Invasive species represent a serious threat to natural ecosystems through a range of negative effects on native species in the region invaded. The invasive species Sargassum muticum has invaded several temperate regions worldwide including the Galician rocky shoreline (northwestern Spain) in Western Europe. The main aim of this study was to assess if colonization by S.
