Several devices have been designed to prevent predation in nest boxes by mammals and birds. Although snakes are one of the most common predators in cavity–nesters, they have always been difficult to deter. Here we tested ...
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.
The methods used to preserve bird skins in museums have a potentially crucial impact on the feasibility and use of these specimens as a source of biological knowledge, although this subject is rarely broached. Study skins ...
Biological invasions are the second most important cause of species extinction. Aided by processes such as transportation and urbanization, exotic species can establish and spread to new locations, causing changes in the ...
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 ...
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 ...
The area of the Montseny mountain whre the population of Rana temporaria lives is described. That mountain is part of the Catalonian Prelitoral System, so that it is clearly influenced by the mediterranean climate. ...
An extensive compilation of the available literature regarding marine Turtles on the spanish coasts have been completed, giving at the same time further unpublished observations. The 99 references obtained are shared between ...
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 ...
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 ...
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 ...
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 ...
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 ...
