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 ...
Adaptive responses of animals to climate change are most likely insufficient
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 ...
Diet assessments as a tool to control invasive species: comparison between Monk and Rose-ringed parakeets with stable isotopes
Food is a main limiting factor for most populations. As a consequence, knowledge about the diet of invasive alien species determines the design of control measures. The Monk and Rose-ringed parakeets are two typical species ...
Diet to tissue discrimination factors for the blood and feathers of the monk parakeet (Myiopsitta monachus) and the ring–necked parakeet (Psittacula krameri)
Diet to tissue discrimination factors for the blood and feathers of the monk parakeet (Myiopsitta monachus) and the ring–necked parakeet (Psittacula krameri). Stable isotope analyses (SIAs) have been widely used in recent ...
Do invasive mosquito and bird species alter avian malaria parasite transmission?
Alien mosquito and vertebrate host species may create novel epidemiological scenarios for the transmission of pathogens naturally circulating in the invaded area. The exotic Monk parakeet (Myiopsitta monachus) has established ...
Beak morphology predicts apparent survival of crossbills: due to selective survival or selective dispersal?
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 ...
The roles of temperature, nest predators and information parasites for geographical variation in egg covering behaviour of tits (Paridae)
Aim Nest building is widespread among animals. Nests may provide receptacles for eggs, developing offspring and the parents, and protect them from adverse environmental conditions. Nests may also indicate the quality of ...
Microsatellite characterisation and sex-typing in two invasive parakeet species, the monk parakeet Myiopsitta monachus and ring-necked parakeet Psittacula krameri
Invasive species can have wide-ranging negative impacts, and an understanding of the process and success of invasions can be vital to determine management strategies, mitigate impacts and predict range expansions of such ...
En memòria de Roser Nos: una breu història d’algú que va estimar i potenciar l’ornitologia
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 ...
45 anys d’ornitologia de muntanya i el Grup Bages d’Anellament
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 ...
