AbstractIn this paper, we present a first estimation, using the GIPSY-OASIS software, of the crustal velocity and strain rate fields in the Balearic Islands (Spain), based on continuous GPS observations from the XGAIB network spanning the period 2010-2013. The XGAIB network consists of nine permanent, widely distributed stations that have operated continuously since 2010. In this paper, we describe the XGAIB network and the CGPS data processing and present our principle results in terms of the position time series and velocities of all of the sites, which were observed for more than three and a half years. In addition, strain tensors were estimated from the velocity field to obtain the first realistic crustal deformation model of the archipelago.The strains exhibit gradual variation across the Balearic Islands, from WNW-ESE extension in the southwest (Ibiza and Formentera) to NW-SE compression in the A c c e p t e d M a n u s c r i p t 2 northeast (Menorca). These results constitute an advance in our knowledge of the tectonics of the western Mediterranean region. Highlights-We model the crustal velocity and strain rate fields in the Balearic Islands.-We use continuous GPS observations from a permanent GNSS network.-The strains exhibit gradual variation from WNW-ESE in the southwest to NW-SE in the northeast.

Stock boundaries for fisheries assessment and management in the Mediterranean: the Balearic Islands as a case study

et al. 2011

View full text Add to dashboard Cite

SUMMARY:The stock concept plays a pivotal role in fisheries assessment and management. Stocks are defined according to biological, geographical, economic or socio-political factors. The General Fisheries Commission for the Mediterranean (GFCM) has established thirty management geographical sub-areas (GSAs) based on political and statistical considerations rather than biological or economic factors. Here, we present our view on the main biological and ecological aspects that should be considered for delineating different management units in the Mediterranean. We focus on the Balearic Islands (GSA05) as a case study highlighting its specificities compared to the adjacent coast of the Iberian Peninsula (GSA06), but the approach could be generalized to the problem of identifying stock boundaries in other areas. The work is based on published information from different marine disciplines such as geomorphology, ecology and fisheries, combined with the analysis of new data coming from official fishery statistics and scientific surveys. This approach avoids the important drawbacks (inconclusive results, high costs) of other time-consuming techniques used in stock identification, such as genetics. According to the information presented, we conclude that GSA05 should be maintained as an individualized area for assessment and management purposes in the western Mediterranean.Keywords: stock boundary, fishery assessment and management, General Fisheries Commission for the Mediterranean (GFCM), Balearic Islands, Mediterranean Sea. RESUMEN: Definición de límites en la evaluación y gestión de stocks mediterráneos: las Islas Baleares como caso de estudio. -El concepto de stock juega un papel clave en la evaluación y gestión de pesquerías. Los stocks se definen en base a factores biológicos, geográficos, económicos o socio-políticos. La Comisión General de Pesca para el Mediterráneo (CGPM) ha establecido treinta subáreas geográficas de gestión (GSAs) basándose más en consideraciones políticas y estadísti-cas que en factores biológicos o económicos. En este trabajo presentamos nuestro punto de vista sobre los principales aspectos que deberían considerarse para definir diferentes unidades de gestión en el Mediterráneo. Aunque nos hemos centrado en las Islas Baleares (GSA05) como caso de estudio, resaltando sus especificidades en relación a las costas adyacentes de la Península Ibérica (GSA06), el enfoque podría generalizarse al problema de la identificación de stocks en otras áreas. El trabajo combina el uso de información publicada de diferentes disciplinas marinas como la geomorfología, ecología y pesquerías, con el análisis de datos inéditos procedentes de estadísticas pesqueras oficiales y campañas científicas. El enfoque que presentamos evita importantes inconvenientes (resultados no concluyentes, elevados costes) de otras técnicas más complejas y laboriosas utilizadas en la identificación de stocks como la genética. En base a la información presentada, concluimos que la GSA05 debería mantenerse como un área individualizada pa...

“…The sampling sites were located over 200 and 900 m depth (shelf break and middle slope, respectively) and present different environmental conditions (Pinot et al 2002;López-Jurado et al 2008). At the southern station of Mallorca, the upper slope is irregular, with numerous small canyons, while it is smooth in the northern station (Acosta et al 2002). Two additional polychelid zoeal stages were captured between 300 and 400 m depth over the slope of Blanes canyon (NW Mediterranean) during 2004 under the ''Observation, analysis and modelling of the Mediterranenan Sea'' (OAMMS-04) survey, and were also used for photographic record.…”

Larval stages of the deep-sea lobster Polycheles typhlops (Decapoda, Polychelida) identified by DNA analysis: morphology, systematic, distribution and ecology

et al. 2014

A total of 25 specimens of Eryoneicus larvae were collected near the Balearic Archipelago (Western Mediterranean Sea) in 2009 and 2010. Detailed morphological examination indicated that the smallest individual corresponded with the first zoea (ZI) stage of Polycheles typhlops hatched from a berried female by Guerao and Abelló (J Nat Hist 30(8): [1179][1180][1181][1182][1183][1184] 1996). Only two species of deep-sea polychelid lobster, namely P. typhlops and Stereomastis sculpta, are known to occur in the Mediterranean. Genetic distance comparisons and phylogenetic analysis of the mitochondrial 16S rDNA and Cox I genes of this early larva together with adults from several Polycheles and Stereomastis species allowed us to assign it to P. typhlops. This is the first wild-caught larval stage of a polychelid lobster being identified using molecular techniques. The remaining specimens were attributed to zoeal stages II-III and decapodid stage based on morphological comparison. The arrangement of spines along the anterior part of the middorsal line (R, 1, 1, 1, 2, C 1 ), characteristic of the former species E. puritanii, discriminates these larvae from other Eryoneicus found in the Mediterranean. The clear presence of epipods on the third maxilliped and pereiopods of the decapodid stage gives further support to the identification of E. puritanii as the larval stages of P. typhlops. Additionally, information on the ecology of these larvae, their abundances during different seasons, as well as their bathymetric distribution is reported.
