Recent spread of blue tits into the Barcelona urban environment: morphological differences and the role of balanced dispersal
Sign Up to like & getrecommendations! Published in 2020 at "Evolutionary Ecology"
DOI: 10.1007/s10682-020-10087-5
Abstract: 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 changes in… read more here.

DOI: 10.1016/j.anbehav.2017.09.004
Abstract: Divorce occurs when both members of a breeding pair survive to the following year but then pair with other individuals instead of reuniting. Divorce is common in birds, but its frequency can vary widely both… read more here.

DOI: 10.1093/beheco/arac044
Abstract: Abstract In species with mutual mate choice, we should expect adaptive signaling in both sexes. However, the role of female sexual signals is generally understudied. A case in point is female birdsong that has received… read more here.

DOI: 10.1093/beheco/arw148
Abstract: Lay Summary The pace-of-life syndrome hypothesis predicts that environmental differences can trigger the evolution of different life-history strategies, including differences in personality. A 5-year study reveals that blue tits breeding in different habitats differ in… read more here.

Micro Germline-Restricted Chromosome in Blue Tits: Evidence for Meiotic Functions
Sign Up to like & getrecommendations! Published in 2023 at "Molecular Biology and Evolution"
DOI: 10.1093/molbev/msad096
Abstract: Abstract The germline-restricted chromosome (GRC) is likely present in all songbird species but differs widely in size and gene content. This extra chromosome has been described as either a microchromosome with only limited basic gene… read more here.

Blue tits are outperformed by great tits in a test of motor inhibition, and experience does not improve their performance
Sign Up to like & getrecommendations! Published in 2023 at "Royal Society Open Science"
DOI: 10.1098/rsos.221176
Abstract: Motor inhibition refers to the ability to inhibit immediate responses in favour of adaptive actions that are mediated by executive functions. This ability may be an indication of general cognitive ability in animals and is… read more here.

Elevated Immune Gene Expression Is Associated with Poor Reproductive Success of Urban Blue Tits
Sign Up to like & getrecommendations! Published in 2017 at "Frontiers in Ecology and Evolution"
DOI: 10.3389/fevo.2017.00064
Abstract: Urban and forest habitats differ in many aspects that can lead to modifications of the immune system of wild animals. Altered parasite communities, pollution and artificial light at night in cities have been associated with… read more here.

DOI: 10.3390/d15050609
Abstract: Filarioid nematodes (commonly known as filarial worms) are known to impact human and domestic animal health, but studies examining their ecological relevance and impacts on wildlife are still underrepresented. In the case of birds, microfilariae… read more here.

The Immediate Impact of Ringing, Blood Sampling and PIT-Tag Implanting on the Behaviour of Blue Tits Cyanistes caeruleus
Sign Up to like & getrecommendations! Published in 2018 at "Ardea"
DOI: 10.5253/arde.v106i1.a8
Abstract: Blood sampling from the brachial vein and sub-cutaneous implantation of PIT-tags (‘passive integrated transponders’) are techniques widely practiced in ornithological research. Longer-term consequences of these procedures (across months or years) have been studied in detail.… read more here.
