Bird populations most exposed to climate change are less sensitive to climatic variation
The phenology of many species shows strong sensitivity to climate change; however, with few large scale intra-specific studies it is unclear how such sensitivity varies over a species’ range. We document large intra-specific ...
Epigenetics and the city: non-parallel DNA methylation modifications across pairs of urban-forest Great tit populations
Identifying the molecular mechanisms involved in rapid adaptation to novel environments and determining their predictability are central questions in evolutionary biology and pressing issues due to rapid global changes. ...
Sex and age effects on monk parakeet home-range variation in the urban habitat
Home-range size is a key aspect of space-use, and variation in home-range size and structure may have profound consequences for the potential impact of damage and control strategies for invasive species. However, knowledge ...
Dietary plasticity in an invasive species and implications for management: the case of the monk parakeet in a Mediterranean city
Behavioural flexibility may play a relevant role during invasion of a new habitat. A typical example of behavioural flexibility favouring invasion success refers to changes in foraging behaviour. Here we provide data on ...
A comparison of the diet of urban and forest great tits in a Mediterranean habitat
The low breeding performance and body condition of nestling passerine birds in urban environments has been attributed to the poor quality and low abundance of food in these settings. However, detailed data on prey provided ...
The role of monk parakeets as nest-site facilitators in their native and invaded areas
While most of the knowledge on invasive species focuses on their impacts, little is known about their potential positive effects on other species. Invasive ecosystem engineers can disrupt recipient environments; however, ...
Are plumage colour and song redundant ornaments in great tits (Parus major)? It depends on the colour
According to current theory, the development of different conspicuous ornaments may provide multiple, redundant or unreliable information. However, multiple visual and acoustic traits have not often been tested at the same ...
Leaf bathing in ring-necked parakeets Psittacula krameri
Una de las principales acciones en el cuidado y limpieza del plumaje de las aves es el baño. Las aves pueden bañarse en agua, nieve, polvo e incluso hormigas. Está más raramente descrito el baño con hojas, en el que las ...
Continent-wide genomic signatures of adaptation to urbanisation in a songbird across Europe
Urbanisation is increasing worldwide, and there is now ample evidence of phenotypic changes in wild organisms in response to this novel environment. Yet, the genetic changes and genomic architecture underlying these ...
Fine‐scale genetic structure reflects limited and coordinated dispersal in the colonial monk parakeet, Myiopsitta monachus
The genetic structure of animal populations has considerable behavioural, ecological and evolutionary implications and may arise from various demographic traits. Here, we use observational field data and molecular genetics ...
Roser Nos: la zoologia al servei de la ciutadania
Roser Nos Ronchera (1924-2018) és un bon exponent de científica capaç de superar, amb gran tenacitat, un reguitzell d’adversitats per desenvolupar una llarga i notable carrera. Nascuda en un poble petit i allunyat, es va ...
Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal
Rates of phenotypic change are greater in cities than in any other habitat. Consequently, urban habitats are an ideal experimental area to study contemporary evolution and adaptation. A key question related to phenotypic ...
Fluctuating optimum and temporally variable selection on breeding date in birds and mammals
Temporal variation in natural selection is predicted to strongly impact the evolution and demography of natural populations, with consequences for the rate of adaptation, evolution of plasticity, and extinction risk. Most ...
Connecting the data landscape of long‐term ecological studies: the SPI‐Birds data hub
1. The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long‐term studies of individually marked animals are not an ...
Nicarbazin has no effect on reducing feral pigeon populations in Barcelona
BACKGROUND: Nicarbazin is an anti-coccidial product sometimes used as a contraceptive to reduce the size of feral pigeon populations. However, its effectiveness in reducing pigeon population size in cities has generated ...
Mosquitoes in an urban zoo: identification of blood meals, flight distances of engorged females, and avian malaria infections
Zoological gardens are home to a large number of vertebrate species and as such are suitable sites for both mosquito breeding and maintenance. They are excellent places for entomological studies of mosquito phenology, ...
Interaction of climate change with effects of conspecific and heterospecific density on reproduction
We studied the relationship between temperature and the coexistence of great tit Parus major and blue tit Cyanistes caeruleus, breeding in 75 study plots across Europe and North Africa. We expected an advance in laying ...
