El objectivo de este estudio es evaluar la afluencia de visitantes que acuden al Museo de Zooología e Barcelona, intentando conocer: 1. Si existe algun tipo de dinámica en la afluencia del público individual 2. Si la ...
Many animals show behavioural syndromes (i.e. suites of correlated behaviours across multiple situations). These behavioural correlations, however, imply limitations in the behavioural plasticity of individuals when facing ...
A standard approach to model how selection shapes phenotypic traits is the analysis of capture–recapture data relating trait variation to survival. Divergent selection, however, has never been analyzed by the capture–recapture ...
BACKGROUND: As feeding by humans is one of the main food resources to pigeons (Columba livia), there is general agreement that public education that aims to reduce the food base may be the most feasible way to reduce ...
Most examples of adaptation to the urban environment relate to plasticity processes rather than to natural selection. Personality, however, defined as consistent individual differences in behaviour related to ...
The diet of wild animals has been studied using many different strategies, approaches and methods in recent decades. In this regard, stable isotopes analysis (SIA) is becoming a widespread tool, but no study has yet, to ...
Epigenetic modifications can respond rapidly to environmental changes and can shape phenotypic variation in accordance with environmental stimuli. One of the most studied epigenetic marks is DNA methylation. In the present ...
ABSTRACTAimEffective policy and management responses to the multiple threats posedby invasive alien species (IAS) rely on the ability to assess their impacts beforeconclusive empirical evidence is available. A plethora of ...
Roser Nos ens ha deixat un rastre poc ortodox de complicitat amb l’ornitologia. Una cerca a les xarxes web no serviria per dimensionar correctament l’impacte que va tenir sobre l’estudi dels ocells. Aquesta breu semblança ...
Bird plumage is often very colorful and can communicate the quality of the bearer to conspecifics. These plumage-based signals of quality are composed of multiple pigments (e.g., melanin and carotenoids). Therefore, sex ...
Parasite-mediated competition has been reported to be one of the most harmful, although overlooked, impacts that alien species have on native ecosystems. Monk parakeets Myiopsitta monachus are successful invaders in Europe, ...
En aquest article s’aporten dades històriques sobre l’origen i el tarannà del Grup Bages d’Anellament (GBA) i del paper que aquest ha jugat en l’estudi de l’ornitologia de muntanya. Alhora, completa alguns aspectes sobre ...
Hypersensitivity pneumonitis (HP) is usually caused by the inhalation of avian and fungal proteins. The present study assesses a cohort of Urban Pest Surveillance and Control Service (UPSCS) workers with high exposure to ...
Aquest article, a més de mostrar la importància dels pins en el cicle biològic de la llucareta Carduelis citrinella, té com objectiu posar en relleu el paper que té la pinassa Pinus nigra en la hivernada de l’espècie i en ...
Many species only show sexual dimorphism at the age of maturity, such that juveniles typically resemble females. Under these circumstances, estimating accurate age‐specific demographic parameters is challenging. Here, we ...
BACKGROUND: The monk parakeet Myiopsitta monachus (Boddaert), native to South America, is an invasive species in several European countries, causing crop damage and potential negative impacts on wildlife. Only Spain and ...
Breeding parameters for Monk Parakeets Myiopsitta monachus nesting in Barcelona, Spain, were collected for 651 nests over five breeding seasons. This invasive population has a high reproductive capacity compared with the ...
Biological responses to climate change have been widely documented across taxa and regions, but it remains unclear whether species are maintaining a good match between phenotype and environment, i.e. whether observed trait ...
Dozens of morphologically differentiated populations, subspecies and species of crossbills (genus Loxia) exist. It has been suggested that this divergence is due to variation in the conifer cones that each population ...
