Current regeneration patterns at treeline in the Pyrenees indicate similar recruitment processes irrespective of past disturbance regime
Aim: Impacts of global change, such as land-use and climate changes, could produce significant alterations in the elevational patterns of alpine tree line ecotones and their adjacent vegetation zones. Because the responses ...
MEDFATE 2.9.3: a trait-enabled model to simulate Mediterranean forest function and dynamics at regional scales
Regional-level applications of dynamic vegetation models are challenging because they need to accommodate the variation in plant functional diversity, which requires moving away from broadly defined functional types. ...
Seedling recruitment, survival and facilitation in alpine <em>Pinus uncinata</em> treeline ecotones. Implications and potential responses to climate warming
Aims: Alpine tree line ecotones are harsh environments where low temperatures constrain tree regeneration and growth. However, the expected upward shift of tree line ecotones in response to climate warming has not been ...
Activity and space patterns of Pyrenean desman (Galemys pyrenaicus) suggest non-agressive and non-territorial behaviour
The Pyrenean desman is considered a flagship species for biodiversity and evolution. However, its scientific knowledge is still under development and currently on debate, particularly in relation to its behavioural ecology ...
Is the standard Eurasian otter Lutra lutra survey strategy suitable for surveying the American mink Neovison vison?
The American mink Neovison vison is an elusive mustelid that is monitored mostly through the detection of its field signs, namely, footprints and scats. In Europe, the American mink has been often monitored using the ...
New insights into social and space use behaviour of the endangered Pyrenean desman (<em>Galemys pyrenaicus</em>)
We describe novel aspects of the social organisation of the Pyrenean desman, Galemys pyrenaicus, by studying home range and shelter use behaviour in a local population. A total of 45 individuals were trapped of which 20 ...
Causes and patterns of human-induced mortality in the Critically Endangered European mink Mustela lutreola in Spain
Human intervention is the main cause of the decline of the Critically Endangered European mink Mustela lutreola. In this study we analysed the main causes of direct human-caused mortality of the species in Spain. A total ...
Morphological variation of introduced species: the case of American mink (Neovison vison) in Spain
We studied the morphology of American mink Neovison vison in five out of the six introduced populations in Spain. The spatial and temporal variation of body weight (BW), body length (BL), tail length, hind-foot length and ...
Evaluating the effect of <em>American mink</em>, an alien invasive species, on the abundance of a native community: is coexistence possible?
Loss of biodiversity due to biological invasions is one of the most critical issues our society is facing. American mink is one of the most nefarious invasive non-native species and has major consequences for diversity, ...
Framework for deep learning diagnosis of plant disorders in horticultural crops: From data collection tools to user-friendly web and mobile apps
Food security is a pressing global concern, particularly highlighted by the United Nations Sustainable Development Goal 2 (SDG 2), which focuses on enhancing the productivity and incomes of smallholder farmers. In the ...
Buccal dental-microwear and feeding ecology of Early Pleistocene Theropithecus oswaldi from Cueva Victoria (Spain)
Despite the scarcity of fossil specimens of Theropithecus oswaldi in Eurasia, its presence out of Africa attests to the great dispersal of this Papionini genus during the Early Pleistocene. In the present study, we analyze ...
Face-brain correlates as potential sex-specific biomarkers for schizophrenia and bipolar disorder
Given the shared ectodermal origin and integrated development of the face and the brain, facial biomarkers emerge as potential candidates to assess vulnerability for disorders in which neurodevelopment is compromised, such ...
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 ...
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 ...
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) ...
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 ...
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. ...
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 ...
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 ...
