Experimental evidence that intra-specific competition in seagrass meadows reduces reproductive potential in the sea urchin Paracentrotus lividus (Lamarck)
To better understand the biological controls that regulate sea urchin dynamics, we studied the effects of potential inter- and intra-specific competition for food on several biological variables of the main sea urchin in ...
Schizophrenia polygenic risk score in psychosis proneness
Schizophrenia (SZ) is a complex disorder with a highly polygenic inheritance. It can be conceived as the extreme expression of a continuum of traits that are present in the general population often broadly referred to as ...
Unreported catches, impact of whaling and current status of blue whales in the South European Atlantic Shelf.
The North Atlantic blue whale was depleted by modern whaling and it is still considered to be highly endangered. Despite its protection in 1954, catches continued in the South European Atlantic Shelf (SEAS) region and ...

Sea slug night fever: 39 new records of elusive heterobranchs in the western Mediterranean (Mollusca: Gastropoda)
Citizen (or community) science has provided copious and valuable information about charismatic marine taxa such as heterobranch gas- tropods, thus contributing enormously to the known geographic dis- tribution of many sea ...
Water stress protection by the arbuscular mycorrhizal fungus<em> Rhizoglomus irregulare</em> involves physiological and hormonal responses in an organ-specific manner
Arbuscular mycorrhizal fungi may alleviate water stress in plants. Although several protection mechanisms have already been described, little information is available on how these fungi influence the hormonal response to ...
Towards understanding the organisation of metacommunities in highly dynamic ecological systems.
Community ecology recognises today that local biological communities are not only affected by local biotic interactions and abiotic environmental conditions, but also by regional processes (e.g. dispersal). While much is ...
Spatial variability and temporal trends in water-use efficiency of European forests
The increasing carbon dioxide (CO2) concentration in the atmosphere in combination with climatic changes throughout the last century are likely to have had a profound effect on the physiology of trees: altering the carbon ...
Stable oxygen isotopes reveal habitat use by marine mammals in Rio de la Plata estuary and the adjoining Atlantic Ocean
Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of marine mammals along the ...
Tooth crown size and dentine exposure in Australopithecus and early Homo: testing hypotheses of dietary related selective preasures
Preliminary analyses of total crown area and dentine exposure surfaces in a sample of hominid teeth seem to indicate that a significant correlation between tooth size and occlusal abrasion occurs, most probably related to ...
Smittia pratti sp. n., a new riparian species from the up-per basin of the Cinqueta River, Spanish Pyrenees [Diptera, Chironomidae, Orthocladiinae]
Male adult of Smittia pratti sp. n. is described on the basis of material collected by sweep net in the upper basin of the Cinqueta River (Spanish Pyrenees, NE-Spain, altitude 1561 m). A combination of some distin-guishing ...
Conectividad en organismos marinos: Aplicaciones para la conservación
El estudio de la conectividad de especies marinas en el Parque Nacional de Cabrera arroja conclusiones útiles para su gestión. Algunas especies de invertebrados clave en los sistemas rocosos están significativamente aisladas ...

Describimos la estructura de un ecotono bosque subalpino-pastos alpinos en los Pirineos Centrales, que incluye los límites altitudinales del bosque y del árbol y está dominado por Pinus uncinata Ram. Para cada individuo ...
Leapfrog migration and habitat preferences of a small oceanic seabird, Bulwer's petrel (Bulweria bulwerii)
Aim Our current understanding of migratory strategies and the reasons for their high variability along the phylogenetic tree remains relatively poor. Most of the hypotheses relating to migration have been formulated for ...
Sea Urchins Predation Facilitates Coral Invasion in a Marine Reserve
Macroalgae is the dominant trophic group on Mediterranean infralittoral rocky bottoms, whereas zooxanthellate corals are extremely rare. However, in recent years, the invasive coral Oculina patagonica appears to be increasing ...
Twin study designs as a tool to identify new candidate genes for depression: A systematic review of DNA methylation studies
Monozygotic (MZ) twin studies constitute a key resource for the dissection of environmental and biological risk factors for human complex disorders. Given that epigenetic differences accumulate throughout the lifespan, the ...
