Hidden in the sand: phylogenomics unravel an unexpected evolutionary history for the desert-adapted vipers of the genus Cerastes
The desert vipers of the genus Cerastes are a small clade of medically important venomous snakes within the family Viperidae. According to published morphological and molecular studies, the group is comprised by four species: ...
Niche shifts over spread of a biological invasion: unveiling the role of changing habitat preference and density-dependence
Aim Anticipating the ultimate fraction of a landscape that might be susceptible to invasion is challenging as several species are able to expand the range of environmental conditions used over invasion. Despite its ...
Sensitization to avian and fungal proteins in diferent work environments
Introduction Hypersensitivity pneumonitis (HP) is usually caused by the inhalation of avian and fungal proteins. The present study assesses a cohort of Urban Pest Surveillance and Control Service (UPSCS) workers with high ...
Evidence for vocal signatures and voice-prints in a wild parrot
In humans, identity is partly encoded in a voice-print that is carried across multiple vocalizations. Other species also signal vocal identity in calls, such as shown in the contact call of parrots. However, it remains ...
Dispersal behaviour and settlement in an invasive bird: dispersers prefer their natal habitat
Habitat selection has profound consequences for individual fitness, but how do animals decide where to settle? The natal habitat preference induction (NHPI) hypothesis proposes that individuals choose habitats that exhibit ...
Breeding great tit Parus Major individuals have moderately consistent foraging niches across years
Diet specialisation during brood rearing has important consequences on parental reproductive success and on the recruitment rate of offspring. However, very little is known about the long-term consistency of parents when ...
Longevity records of citril finches Carduelis citrinella: analysing 43 years of continuous ringing
Longevity records (maximum lifespan) of free-ranging birds are basic to understand the evolution of avian senescence patterns. Here we provide minimum longevity records for the citril finch Carduelis citrinella, an endemic ...
The effect of climate change on avian offspring production: a global meta-analysis
Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders ...
Heterospecific nest material kleptoparasitism: observations of grey herons, Ardea cinerea, removing material from the nests of monk parakeets, Myiopsitta monachus
Nest material kleptoparasitism occurs when an individual steals material from another individual's nest. Here we document 69 observations of grey herons, Ardea cinerea, removing nest material from the nests of monk parakeets, ...
Long-distance dispersal of monk parakeets
Las especies invasivas amenazan la biodiversidad en todo el mundo y, por ello, en el ámbito de la biología de la conservación se considera prioritario determinar las causas y mitigar los efectos de este fenómeno. Uno de ...
Temperature synchronizes temporal variation in laying dates across European hole-nesting passerines
Identifying the environmental drivers of variation in fitness-related traits is a central objective in ecology and evolutionary biology. Temporal fluctuations of these environmental drivers are often synchronized at large ...
The diet of Monk Parakeet nestlings (Myiopsitta monachus) in an urban area: a study using stable isotopes
Capsule: Previous observations in Barcelona and other cities showed that approximately 40% of the food ingested by adult Monk Parakeets Myiopsitta monachus is of anthropogenic origin. Here we show that this type of food ...
Risk-taking coping style correlates with SERT SNP290 polymorphisms in free-living great tits
The coping style of an individual in relation to potentially dangerous situations has been suggested to be inherited in a polygenic fashion, SERT being one of the candidate genes. In this study, we assessed in free-living ...
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 ...
