Contrasting vital rate contributions across interconnected populations of a highly vagile avian scavenger: A multisite modelling approach
Identifying the key drivers of population dynamics in long-lived species is critical for understanding their life history and guiding conservation. However, dispersal processes like immigration and emigration are often ...
Filling the gap: The unique isotopic niche of medium-sized and large sharks in the northwestern Mediterranean Sea
The Mediterranean Sea is considered a biodiversity hotspot and hosts a broad diversity of shark species. Unfortunately, many shark populations have suffered a long story of overexploitation and their abundance has strongly ...
A comprehensive spatial analysis of invertebrate diversity within intermittent stream networks: Responses to drying and land use
Freshwater ecosystems are highly vulnerable to the impacts of climate change, which affect both diversity and ecosystem functioning. Furthermore, these ecosystems face additional threats from human activities, such as ...
Chlorination Cessation Alters Greenhouse Gas Dynamics in Artificial Urban Ponds
Cities are facing an ecological challenge, and international policies are increasingly focused on implementing nature-based solutions to support this transition. In this context, the naturalization of artificial urban ponds ...
Schizophrenia Following Early Adolescence Prodrome: A Neurodevelopmental Subtype With Autism-like Sensorimotor and Social Cognition Deficits
Background and Hypothesis While age at onset in schizophrenia (SCZ) is usually defined by age at onset of psychosis, the illness actually occurs earlier, with a prodrome often starting in childhood or adolescence. We ...
Secuenciación de ADN antiguo de restos humanos del País Vasco
Se ha recuperado DNA mitocondrial (región 1 del D-loop) de tres individuos procedentes del yacimiento vasco de época altomedieval de Alto de la Ermita (Amézaga, Araba), mediante la técnica de PCR (reacción en cadena de la ...
Sexual reproduction of actively restored gorgonians
Corals and gorgonians play an important role as ecosystem engineers in many sublittoral communities worldwide. However, coral populations are being increasingly impacted by human activities. Active ecological restoration ...
A combined phylogenetic strategy illuminates the evolution of Goniodorididae nudibranchs (Mollusca, Gastropoda, Heterobranchia)
Goniodorididae is a family of small dorid nudibranchs distributed worldwide that feed on entoprocts, ascidians, and bryozoans. The evolutionary relationships between its taxa have been uncertain due to the limited taxa ...
Environmental and overgrazing effects on diatom communities in high mountain mires
High mountain mires are affected by anthropogenic activities such as livestock, which have changed land use, fragmented habitats, and affected the structure and functioning of aquatic communities such as diatoms. Diatoms ...
Diversity of planktonic and benthic communities in the high‐altitude Salar de Pedernales basin, Atacama Desert, Chile
Salar de Pedernales basin is located at 3370 meters above sea level in the Atacama Desert, Chile, covering an area of 3620km2. This ecosystem is characterized by high exposure to ultraviolet radiation, low humidity, huge ...
Restoring High Mountain Sphagnum Communities in the Central Pyrenees
A handful of Sphagnum species and their ecosystems find their southernmost occurrence in the Pyrenees, and these small, relict units are endangered through anthropic activities and climatic change. A number of hydropower ...
Omnipresents, però secrets i desconeguts: els líquens. Una ullada al Parc de Montnegre i el Corredor
Des que al segle XIX Schwendener (1869), amb l’ajuda del microscopi, va descobrir que els líquens no eren plantes sinó fongs amb algues dins, s’han fet molts estudis sobre els organismes presents al tal·lus (el cos vegetatiu) ...
La capacidad de producción de los océanos
Ya no se habla tanto, con entonación retórica, de los recursos ilimitados del mar, pero se sigue especulando con mayor motivación práctica sobre las posibilidades de incrementar la extracción de proteínas alimenticias de ...
Order within chaos: potential migratory strategies and individual associations in fin whales feeding off Iceland
Background: The life cycle of most baleen whales involves annual migrations from low-latitude breeding grounds to high latitude feeding grounds. In most species, these migrations are traditionally considered to be carried ...
Characterizing decision-making and reward processing in bipolar disorder: A cluster analysis
The presence of abnormalities in emotional decision-making and reward processing among bipolar patients (BP) has been well rehearsed. These disturbances are not limited to acute phases and are common even during remission. ...
No detrimental effects of wing-harnessed GPS devices on the breeding performance of Yellow-legged Gulls (Larus michahellis): A multy-colony evaluation
A recent study revealed that wing-harnessed tracking devices negatively affected reproductive success of Great Black-backed Gulls Larus marinus. To evaluate the generality of this effect in large gulls, we investigated the ...
Theory of mind in schizophrenia through a clinical liability approach: a sib-pair study.
Background: Consistent findings indicate that Theory of Mind (ToM) is impaired in schizophrenia (SZ). To investigate whether such deficits are trait- or state-dependent, we investigated if ToM is modified by clinical ...
Theory of mind in schizophrenia through a clinical liability approach: a sib-pair study.
<strong> Background: </strong> Consistent findings indicate that Theory of Mind (ToM) is impaired in schizophrenia (SZ). To investigate whether such deficits are trait- or state-dependent, we investigated if ToM is modified ...

Intergenerational effects of maternal childhood maltreatment on newborns' stress regulation: The role of maternal depressive symptoms
Background: Maternal childhood maltreatment (CM) has been repeatedly associated with negative offspring's emotional outcomes. The dysregulation of the Hypothalamic-Pituitary-Adrenal (HPA) axis has emerged as the main ...
