A Multidisciplinary Approach to Identify Priority Areas for the Monitoring of a Vulnerable Family of Fishes in Spanish Marine National Parks
(Springer Nature, 2021-01-21)[Abstract] Background: Syngnathid fishes (Actinopterygii, Syngnathidae) are flagship species strongly associated with seaweed and seagrass habitats. Seahorses and pipefishes are highly vulnerable to anthropogenic and ... -
An assessment of sample processing methods for stable isotope analyses of coastal foodwebs
(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, ... -

Complex Patterns of Habitat Use by Juvenile Spider Crabs Maja Brachydactila Revealed by Stable Isotope Analyses
(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 ... -
Dogs and Foxes in Early-Middle Bronze Age Funerary Structures in the Northeast of the Iberian Peninsula: Human Control of Canid Diet at the Sites of Can Roqueta (Barcelona) and Minferri (Lleida)
(Springer, 2019-01-14)[Abstract] Findings of canid remains in graves at different sites in the northeast of the Iberian Peninsula are evidence of a widespread funerary practice that proliferated between the end of the 3rd and the 2nd millennium ... -
Equine diet during protohistoric times in the Northeast of the Iberian Peninsula: Stable isotope data (C, N) from bone collagen
(Elsevier, 2021-09-16)[Abstract] The analysis of stable isotopes in bone collagen allows us to infer the diet of the animals studied. This dataset consists of isotopic signatures (δ13C and δ15N) obtained by isotope ratio mass spectrometry from ... -

Estudio de la dieta de la avispa asiática ("Vespa velutina" Lepeletier, 1836) mediante isótopos estables
(2017)[Resumen] Desde su llegada a Europa en 2004, la avispa asiática (Vespa velutina Lepeletier 1836) se ha convertido en un problema ecológico, económico y social. Con este trabajo se pretende contribuir a mejorar el conocimiento ... -
Identification of ambiguous fossil bone remains following 13C and 15N isotopic signals on bone collagen
(Universidade da Coruña, 2001)[Abstract] In this paper we deal with an useful application of isotopic studies on fossil bone remains. Following δ1 3C and δ1 5N signals recorded in bone collagen, it is possible to classify into the proper taxon some ... -
Indicios de pastoreo extensivo en el noroeste peninsular durante el dominio suevo
(Universidade da Coruña, 2015)[Resumen:]Las condiciones edáficas de Galicia (NW de España), debido al sustrato ácido predominante, dificultan la conservación de los restos arqueozoológicos asociados a los asentamientos humanos. En estos casos, la ... -
Los isótopos estables de Carbono y Nitrógeno como biomarcadores para la trazabilidad alimentaria
(2017)[Resumen] El análisis de isótopos estables mediante espectrometría de masas para relaciones isotópicas (E.M.R.I.) es una herramienta clave en la trazabilidad alimentaria por su potencial para reconstruir la dieta de los ... -
Leaf Wax Biomarkers of a High-Mountain Lake Area in Western Iberia—Implications for Environmental Reconstructions
(Frontiers, 2022-11-29)[Abstract] Leaf wax n-alkane biomarkers are widely used to infer past vegetation dynamics and hydroclimate changes. The use of these compounds strongly relies on the characterization of modern plants. However, few studies ... -
