La recerca científica és una part important de l’activitat del Museu des dels seus orígens, amb l’objectiu d’estudiar i interpretar la diversitat de la vida i de les estructures geològiques que li donen suport, amb especial atenció als medis mediterranis.En aquesta tasca, el Museu se centra tant en la recerca basada en les col·leccions com en l’estudi de les espècies en el seu medi natural i avalua les interaccions amb l’entorn i entre elles.

Marine ectotherms, organisms whose body temperature depends on their environment, often rely on physiological plasticity to withstand rapid temperature increases when behavioural adjustments are insufficient. Despite ...
The Mediterranean common dolphin (Delphinus delphis) presents an enigmatic natural history during the past centuries. Widely prevalent in the 19th and early 20th centuries, it faced a significant decline across most of ...
Despite being one of the most abundant animal species in the world, House Sparrow Passer domesticus numbers have declined significantly worldwide in recent decades, above all in urban areas. We studied the influence of ...
The use of two-dimensional (2D) pictures to analyse form variation of three-dimensional (3D) objectsentails measurement error, loss of important information and a possible misinterpretation of real shapechanges. Despite ...
Animals use colours, morphological structures and behaviour to advertise their dominance status and ability to obtain resources (Resource Holding Potential, RHP) in agonistic contexts with conspecifics. Dominance ...
Passerines moult during various life-cycle stages. Some of these moults involve the retention of a variable quantity of wing and tail feathers. This prompts the question whether these partial moults are just arrested ...
Bird feathers have been widely used as environmental indicators, providing key information on environmental pollution. However, there is little available information on the adsorption of natural radioactivity in bird ...
Sequence and intensity are two essential components of bird moult. While the moult sequences of remex tracts are highly homogenous across passerines, other tracts apparently show a high variability. Moreover, order of moult ...
En este trabajo intentamos contribuir a la demarcación de unos límites biogeográficos verdaderos, así conio aportar algunos datos biométricos y morfológicos de los ejemplares recolectados en la zona más septentrional que ...
A recurrent behavioral trait model to study adaptation to urban environments is the flight initiation distance (FID), measured as the distance at which animals flee from an approaching threat. It has previously been shown ...
Many bird species with behavioural plasticity innovate when searching for alternative trophic resources, mainly during periods of energetic constraints, when colonizing new habitats, or during the breeding season when the ...
Urbanization represents a multi-dimensional ecological ‘filter’ for birds determined by a myriad of variables that can change over time. Birds colonising an urban system or staying in a habitat that has been recently ...
Marginal coverts are often neglected in passerine moult studies due to their small size and large number. Here, we document eight moult components of this group of wing coverts in a House Sparrow population from Barcelona ...
Dado que el comportamiento proporciona un marco útil para comprender la especialización, la personalidad animal puede ayudar a explicar la capacidad invasiva de las aves. La invasión implica la dispersión por áreas ...
This note gives fifteen localities for Triturus helveticus in the Province of Catalonia, Spain, and extends the known distribution of the species in a southerly direction.
Extra moult episodes in wild passerines have rarely if ever been documented. Here, we report a case of a possible extra moult episode in a House Sparrow Passer domesticus, a species with just one moult per annual cycle. ...
