Recovery after exploitation of stalked barnacles is facilitated by the presence...
Gómez-del Campo, V.; Arrontes, J.; Cruz, T.; Vázquez, E.; Macho, G.; Thiébaut, E.; Geiger, K.; Fernandes, J.N.; Jacinto, D.; Aguión, A.; Silva, T.We have followed the recovery of gaps produced either by harvesters or by scientists in stands of stalked barnacle (Pollicipes pollicipes) during two years in four regions of Europe (SW Portugal, Galicia and Asturias in Spain and Brittany in France; n = 423 gaps), which was extended to four years in Asturias (n = 252 gaps). The presence of adult conspecifics in the margins of the gaps increased by at least four...
Coping with poachers in European stalked barnacle fisheries: Insights from a st...
Geiger, K.; Rivera, A.; Álvarez, J.; Arrontes, J.; Borrell, Y.J.; Cruz, T.; Davoult, D.; Dubert, J.; Feis, M.; Fernandes, J.N.; Fernández, C.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-managed at small spatial scales (10′s km and less, Galicia and Astu...
Biophysical modelling of larval dispersal and population connectivity of a stal...
Nolasco, R.; Dubert, J.; Acuña, J.L.; Aguión, A.; Cruz, T.; Fernandes, J.N.; Geiger, K.J.; Jacinto, D.; Macho, G.; Mateus, D.; Rivera, A.; Román, S.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. How- ever, confidence on biophysical models, tested by confronting model estimates with empirical evi- dence, is seldomly assessed. We compared time-series estimates of larval supply of the stalked barnacle Pollicipes pollicipes to rock...
Elemental Chemometrics as Tools to Depict Stalked Barnacle (Pollicipes pollicip...
Duarte, B.; Mamede, R.; Duarte, I.A.; Caçador, I.; Tanner, S.E.; Silva, M.; Jacinto, D.; Cruz, T.; Fonseca, V.F.The stalked barnacle Pollicipes pollicipes is an abundant species on the very exposed rocky shore habitats of the Spanish and Portuguese coasts, constituting also an important economical resource, as a seafood item with high commercial value. Twenty-four elements were measured by untargeted total reflection X-ray fluorescence spectroscopy (TXRF) in the edible peduncle of stalked barnacles sampled in six sites a...
Ten years of monitoring recruitment of the edible stalked barnacle Pollicipes p...
Fernandes, J.; Jacinto, D.; Penteado, N.; Sousa, A.; Mateus, D.; Seabra, M. I.; Silva, T.; Castellanos, P.; Castro, J. J.; Cruz, T.Understanding recruitment patterns of an exploited species is essential to predict changes in population dynamics and to improve its management and conservation. Temporal variability in recruitment of the edible stalked barnacle Pollicipes pollicipes was analyzed over a decade (consecutive annual recruitment seasons from 2007 to 2016) at a cape area located in the Canary-Iberia Current Upwelling System (Cape of...
Ecologia do litoral rochoso alentejano
Castro, J. J.; Cruz, T.; Jacinto, D.; Silva, T.Neste artigo são resumidamente apresentados os principais padrões de variação espacial e temporal da abundância e distribuição de macroepibentos do litoral rochoso alentejano, e os principais fatores que os condicionam.

Temporal variation of the fishers’ perception about the stalked barnacle (Polli...
Sousa, A.; Jacinto, D.; Penteado, N.; Pereira, D.; Silva, T.; Castro, J. J.; Leandro, S. M.; Cruz, T.The engagement of the fishers and other stakeholders in the management of the resources is considered the key ingredient for a good fishery governance. The stalked barnacle Pollicipes pollicipes can be considered the most important economic resource on rocky shores of northern Spain and continental Portugal. This species is highly prized as food and it is heavily exploited. The main objective of the present stu...

Spatial and temporal variation of kelp forests and associated macroalgal assemb...
Pinho, D.; Bertocci, I.; Arenas, F.; Franco, J. N.; Jacinto, D.; Castro, João J.; Vieira, R.; Sousa-Pinto, I.; Wernberg, T.; Tuya, F.Kelp communities are in decline in many regions. Detecting and addressing population declines require knowledge of patterns of spatial and temporal variation in the distribution and abundance of kelps and their associated organisms. We quantified kelp and associated macroalgal assemblages three times over a period of 2 years, at three regions along a natural gradient in temperature and nutrient availability acr...
