Conference Paper
Full-text available
Small-scale fisheries support the livelihoods of millions of people worldwide, contributing in terms of food supply and nutrition, jobs and income, and cultural and identity values. Despite this relevance, consideration of small-scale fisheries (SSF onwards) is often lacking from international policies, in part due to the lack of available informat...
Article
Full-text available
Understanding large-scale spatial and temporal patterns of marine populations is a central goal in ecology, which has received renewed attention under climate change. However, few studies explore the large-scale dynamics of populations using standardized protocols and during the same time frames. We studied the phenology and intensity of reproducti...

The stalked barnacle Pollicipes pollicipes inhabits rocky shores from the Atlantic coasts of Brittany (France) to Senegal. Because of the culinary traditions of southern Europe, stalked barnacles represent an important target species for local fisheries on the Iberian Peninsula. To manage this fishery sustainably, it is therefore important to asses...
Article
Full-text available
In January 2020, a stakeholder workshop was organized as a knowledge sharing strategy among European stalked barnacle fisheries. Management of this fishery differs greatly among regions and ranges from less organized and governed at large scales (>100 km, coasts of SW Portugal and Brittany in France) to highly participatory systems which are co-man...
Article
Numerical biophysical models are a standard methodology used to provide estimates of larval dispersal and population connectivity for marine species with a bi-phasic life cycle. However, confidence on biophysical models, tested by confronting model estimates with empirical evidence, is seldomly assessed. We compared time-series estimates of larval...
Article
Despite their remoteness, deep-sea species bioaccumulate mercury, mostly in the form of the neurotoxin methylmercury (MeHg). Although the concentration of MeHg in the water column is known to increase with depth down to a maximum found at the base of the permanent thermocline, the knowledge of the relationship between MeHg content in marine species...
Article
Full-text available
The lack of effective governance is a major concern in small-scale fisheries. The implementation of governance that encompasses the three pillars of sustainability (social, economic, and ecological) is still a worldwide challenge. We examined nine stalked barnacle fisheries (Pollicipes pollicipes) across Southwest Europe to better understand the re...
Article
Full-text available
We developed a new type of generalized depletion model adapted to the rapid life cycle of Octopus vulgaris and the data collection framework put in place in its co-managed small-scale fishery (SSF) in Asturias, northwest Spain. The model uses weekly data from 19 seasons to estimate annual recruitment and female spawners emigration out of the vulner...
Article
Full-text available
The biological pump transports organic carbon produced by photosynthesis to the meso-and bathypelagic zones, the latter removing carbon from exchanging with the atmosphere over centennial time scales. Organisms living in both zones are supported by a passive flux of particles, and carbon transported to the deep-sea through vertical zooplankton migr...

The PERCEBES project aspires to answer questions regarding the effects of harvesting on the intertidal community and recovery potential of stalked barnacle populations after harvesting, for which a Human Exclusion Experiment has been deployed over 2 years in 4 regions: coast of Alentejo (Portugal), Atlantic Islands (Galicia, Spain), Western Asturia...
Article
Despite the growing popularity of bottom-up fishery management schemes not all socio-ecological systems re- spond well to this approach. Unfortunately, due to the heterogeneous nature of socio-ecological systems and lack of long-term, place-based studies we have yet to disentangle the impact of social attributes on their sustain- ability. The goose...

Global patterns of planktonic diversity are mainly determined by the dispersal of propagules with ocean currents. However, the role that abundance and body size play in determining spatial patterns of diversity remains unclear. Here we analyse spatial community structure - β-diversity - for several planktonic and nektonic organisms from prokaryotes...

The gooseneck barnacle fishery in Asturias (N. Spain) has undergone three important changes: (1) the early implementation of a co-management system based on Territorial User Rights for Fishing, (2) a change in management measures (due to a decrease in landings), and (3) an economic crisis. This has allowed us to analyze the systems' sustainability...

We have supplemented available, concurrent measurements of fresh weight (W, g) and body carbon (C, g) (46 individuals, 14 species) and nitrogen (N, g) (11individuals, 9 species) of marine gelatinous animals with data obtained during the global ocean MALASPINA 2010 expedition (totalling 267 individuals and 33 species for the W versus C data; totalli...
Conference Paper
Full-text available
Salps are pelagic tunicates with high feeding, growth and fecal pellet production rates. These features allow them to efficiently graze on algal blooms, rapidly developing dense populations which mediate significant fluxes of organic matter to the bottom. Their complex life cycle, ephemeral appearance and patchy distribution make them difficult to...

With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total fishes biomass. However, recent acoustic observations show that mesopelagic fishes biomass could be significantly larger than the current estimate. Here we combine modelling and a sensitivity analysis of the acoustic observations from the Malaspina 20...

Jellyfishes have functionally replaced several overexploited commercial stocks of planktivorous fishes. This is paradoxical, because they use a primitive prey capture mechanism requiring direct contact with the prey, whereas fishes use more efficient visual detection. We have compiled published data to show that, in spite of their primitive life-st...
