Disconnect between the developing eye and craniofacial prominences in the avian embryo
In the amniote embryo, the upper jaw and nasal cavities form through coordinated outgrowth and fusion of craniofacial prominences. Adjacent to the embryonic prominences are the developing eyes, which abut the maxillary and ...
Biodiversity in storerooms
Zoology collections preserved in museums worldwide contain a broad variety of materials. Designing and adapting storerooms for theses collections is no easy task and is more difficult when reusing existing buildings. ...
La transversalité dans les musées d'histoire naturelle: de la collecte des spécimens aux expositions
The activity of natural history museums is based on the principle of nature sharing. Although no single museum has exclusive rights over a particular fraction of nature, specialised museums and reference centres do exist. ...
La interoperativitat de les eines de descripció de museus, arxius i biblioteques.
El patrimonio de los museos (colecciones, archivos, bibliotecas) y la actividad científica (proyectos de investigación, edición de revistas y monografías) constituyen una plataforma de fuentes documentales diversas y ...
Genotipar sin capturar
En los últimos años, los avances en técnicas moleculares han sido aplicados en taxonomía, ecología, biología evolutiva y biología de la conservación. Es preferible que los estudios genéticos de la fauna salvaje se realcen ...
The primate collection at the Natural Science Museum of Barcelona (Spain)
The Natural Science Museum of Barcelona (MCNB) houses a total of 309 specimens of non–human primates. The collection comprises 102 stuffed animals, 33 skins, 73 skeletons, 24 postcranial skeletons, eight mounted skeletons, ...
Records of fatal attacks by Rose-ringed parakeets "Psittacula krameri" on native avifauna
Interspecific interactions between invasive and native fauna are poorly studied. Here we report six fatal attacks by Rose-ringed Parakeets Psittacula krameri, one of the most successful invasive avian species in Europe, ...
Space invaders: house sparrow densities along three urbanagricultural landscapes
One of the most successful avian urban invaders is the House Sparrow (Passer domesticus). Here, we examine House Sparrow numbers in the urban-agricultural landscape of three cities, one where the sparrow is native (Barcelona) ...
The diet of Great Tit Parus major nestlings in a Mediterranean Iberian forest: the important role of spiders
The diet of the Great Tit Parus major when rearing chicks has been described in many studies. However, data from the Mediterranean area is scarce. Here we describe the diet of nestlings in a population of Great Tits in a ...
Selection based on the size of the black tie of the great tit may be reversed in urban habitats
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 ...
Measurement errors in 3D models used in osteometric data research with freeware: a test using skulls of the algerian hedgehog (Atelerix algirus)
The use of 3D models is becoming commonplace in both scientific investigation and in more general educational activities; nevertheless, methodologies and their associated software are both relatively expensive to use. As ...
Sexy birds are superior at solving a foraging problem
Yellow, red or orange carotenoid-based colorations in male birds are often a signal to prospecting females about body condition, health status and ability to find food. However, this general ‘ability to find food’ has never ...
Is response to fire influenced by dietary specialization and mobility? A comparative study with multiple animal assemblages
Fire is a major agent involved in landscape transformation and an indirect cause of changes in species composition. Responses to fire may vary greatly depending on life histories and functional traits of species. We have ...
