An assessment of sample processing methods for stable isotope analyses of coastal foodwebs
Carabel Chans, Sirka; Godínez Domínguez, Enrique; Verísimo Amor, Patricia; Fernández, Luis; Freire, Juan (2004)[Abstract] The relative abundance of the light and heavy forms of stable isotopes of Carbon and Nitrogen is commonly used in the research of marine food webs. Dehydration of samples is needed for C and N isotopic analysis, ... -

Carabel Chans, Sirka; Verísimo Amor, Patricia; Bernárdez Martí, Cristina; Freire, Juan; Fernández, Luis (2003) -
Complex patterns of habitat use by spider crabs Maja squinado revealed by stable isotope analyses
Freire, Juan; Carabel Chans, Sirka; Verísimo Amor, Patricia; Bernárdez Martí, Cristina; Fernández, Luis (2005)[Abstract] Patterns of habitat use by spider crab juveniles, Maja brachydactila, from two geographic areas in the NW coast of the Iberian Peninsula, were analyzed through the analysis of Carbon and Nitrogen stable isotope ... -
Decomposing diversity patterns of a soft-bottom macroinvertebrate community in the tropical eastern Pacific
Godínez Domínguez, Enrique; Freire, Juan; Franco-Gordo, María del Carmen; González Sansón, Gaspar (2003)[Abstract] Diversity is one of the most frequently used attributes of ecological communities, and there is a long-standing discussion about their adequate use, calculus and interpretation. One of the most conspicuous and ... -
Dynamics of the small-scale spatial structure of a local population of the spider crab, "Maja brachydactyla"
Corgos López-Prado, Antonio; Sánchez Carnero, Noela; Freire, Juan (2005) -
Estacionalidad de la muda terminal y la migración reproductiva en la centolla, "Maja brachydactyla" : evidencias de estrategias de apareamiento alternativas
Corgos López-Prado, Antonio; Verísimo Amor, Patricia; Freire, Juan (2005)[Resumen] Se analiza la temporalidad y sincronización de los procesos de muda terminal, maduración gonadal, acumulación de reservas energéticas y migración en la centolla, Maja brachydactyla, tanto a nivel individual como ... -
Growth at moulth, intermoult period and moulting seasonality of the spider crab "Maja brachydactyla" : combining information from mark-recapture and experimental studies
Corgos López-Prado, Antonio; Sampedro Pastor, María Paz; González-Gurriarán, Eduardo; Freire, Juan (2005)[Abstract] An analysis of growth at moult (for both the prepubertal and terminal moults), moulting seasonality and the intermoult period in the spider crab Maja squinado in the Ría de A Coruña (NW Spain) was carried out ... -
Habitat diversity and postlarval benthic decapod crustacean assemblages in shallow waters of the Ría de A Coruña (NW Spain)
Pallas Lozano, Alicia; García Calvo, Beatriz; Corgos López-Prado, Antonio; Freire, Juan; Godínez Domínguez, Enrique; Bernárdez Martí, Cristina; Sampedro Pastor, María Paz (2003) -
Hierarchical organization of spatial and temporal patterns of macrobenthic assemblages in the tropical Pacific continental shelf
Godínez Domínguez, Enrique; Freire, Juan; Franco-Gordo, María del Carmen; González Sansón, Gaspar (2002)[Abstract] 1. Nowadays, studies focused to test a well-defined set of a priori hypotheses about spatial and temporal organization of assemblages in marine communities are scarce. 2. This study presents the first ... -
Inter-specific comparative analysis of distribution and habitat use patterns of benthic decapod crustaceans in shallow waters
Pallas Lozano, Alicia; García Calvo, Beatriz; Corgos López-Prado, Antonio; Bernárdez Martí, Cristina; Freire, Juan (2005)[Abstract] Coastal areas have been widely considered as nurseries for many marine species. New approaches to this concept take into account interactions among environmental variables and ecological variations related to ... -

Interactions of the fishery of the spider crab Maja squinado with mating, reproductive biology and migrations
Freire, Juan; Fernández, Luis; González-Gurriarán, Eduardo (1998)[Abstract] In this paper different aspects of the fishery and life history of the spider crab Maja squinado in southern Galicia (NW Spain) are analyzed to evaluate the potential effects of the fishery on the sperm limitation ... -
Interannual variability of the diversity and structure of ichthyoplankton assemblages in the central Mexican Pacific
Franco-Gordo, María del Carmen; Godínez Domínguez, Enrique; Freire, Juan (2004)[Abstract] We examined larval fish diversity and assemblage structure on the central Mexican Pacific (coast of Jalisco and Colima) using data from samplings carried out with a Bongo net at 12 stations during 27 months, ... -
Movements of juvenile and adult spider crab ("Maja squinado") in the Ría da Coruña (NW Spain)
Bernárdez Martí, Cristina; González-Gurriarán, Eduardo; García Calvo, Beatriz; Corgos López-Prado, Antonio; Freire, Juan (2003)[Abstract] In August 2002, 12 juvenile and 12 adult (recently terminal moulted) spider crabs were tagged using ultrasonic pingers (Sonotronics, USA) in the Ría da Coruña (NW Spain). Both adults and juveniles were released ... -
Predicting changes to macrobenthic communities due to fishing disturbance in a shrimp fishing ground of the Mexican central Pacific
Godínez Domínguez, Enrique; Freire, Juan; González Sansón, Gaspar (2002)[Abstract] We test predicted short-term structural changes in the macroinvertebrate assemblages of a shrimp fishing ground in the tropical Mexican Pacific subject to low effort with seasonal closures. During two years, ... -
