In a context of the global biodiversity crisis, such as the one in which the planet is found, having accurate information linked to biodiversity monitoring systems is essential to be able to make evidence-based decisions. ...
Los animales despliegan diferentes estrategias de forrajeo a la hora de buscar alimento para su descendencia, mostrando gran variabilidad entre especies, poblaciones e individuos. Este patrón es especialmente acusado en ...
The present dissertation addresses the study of the diversity, systematics, biogeography and evolutionary history of squat lobster superfamily Galatheoidea, founded on integrative taxonomy criteria. Squat lobsters are a ...
[spa] Desde que en el siglo pasado empezaron a tomarse en consideración los entonces incipientes estudios de Biología Marina para racionalizar la pesca de la época, una de las primeras preocupaciones fue la pesca al arrastre, ...
Submarine canyons are major topographic structures forming deep incisions in shelfs and continental margins around the globe. Due to their topographic characteristics, canyons influence both local hydrodynamic conditions ...
Bivalves living in large aggregations of individuals (reefs or beds), such as mussels, clams, cockles and some high trophic predators such as sea stars, play an essential ecological role in the structure, integrity, ...
En esta tesis doctoral se estudia el efecto de una dieta de restricción calórica de mantenimiento a largo plazo (14 meses), en machos de lubina prepúberes, sobre el inicio y desarrollo de la pubertad. Para ello se consideró ...
A major challenge in evolutionary biology is understanding the main drivers that underlie morphological and species diversity. Ecological opportunity—access to new or previously inaccessible niches—has been identified as ...
The study of intraspecific diversity is essential in ecology and evolution as they reveal fine-scale patterns and it is crucial in conservation planning. The main aim of this thesis is to study the evolutionary history of ...
Many topics in ecology and evolution are currently being studied under the framework of eco- evolutionary dynamics that is to say integrating genetic, ecological and demographic data. Here, I have focused my investigations ...
During recent years, jellyfish blooms have become in a passionate issue among marine scientists with a series of studies and reviews. The main concern about this blooms are related with ecosystem and socio-economic impacts ...
The Mediterranean Sea can be considered an excellent natural laboratory for benthic ecologists, due to its peculiar environmental conditions, its broad-scale gradients, and its deep-sea fauna. Primary production levels in ...
La presente Tesis Doctoral está centrada en el centollo atlántico (Maja brachydactyla Balss, 1922). Los objetivos incluyen la optimización del cultivo larvario y el estudio ontogénico del sistema digestivo. El cultivo ...
The study of morphology of organisms has become a widely extended scientific discipline since the beginning of the 20th century, when the scientific community began to establish direct relationships between the anatomical ...
Aiming to improve the conservation status of the European seas, the Marine Strategy Framework Directive (MSFD) was adopted in 2008, establishing a general framework for all EU countries in the field of marine environmental ...
The arid areas of North Africa and Arabia cover a surface of more than 13 million square kilometers and are characterized by their extreme temperatures, diversity of desert habitats and well-adapted flora and fauna. The ...
The study of the non-crustacean invertebrates dwelling on the deep Mediterranean Sea is of interest for different marine science disciplines, being the diversity of species and their distributions largely unexplored. In ...
In the northwestern Mediterranean Sea, anglerfishes Lophius budegassa Spinola, 1807 and Lophius piscatorius Linnaeus, 1758 are among the most valuable demersal species and support an important fishery. Both anglerfishes ...
