[PDF][PDF] Artificial night lighting affects dawn song, extra-pair siring success, and lay date in songbirds

…, P Borgström, P Loës, E Schlicht, M Valcu - Current biology, 2010 - cell.com
Associated with a continued global increase in urbanization [1], anthropogenic light pollution
is an important problem [2]. However, our understanding of the ecological consequences of …

The effects of life history and sexual selection on male and female plumage colouration

J Dale, CJ Dey, K Delhey, B Kempenaers, M Valcu - Nature, 2015 - nature.com
Classical sexual selection theory 1 , 2 , 3 , 4 provides a well-supported conceptual framework
for understanding the evolution and signalling function of male ornaments. It predicts that …

Adaptive sleep loss in polygynous pectoral sandpipers

JA Lesku, NC Rattenborg, M Valcu, AL Vyssotski… - Science, 2012 - science.org
The functions of sleep remain elusive. Extensive evidence suggests that sleep performs
restorative processes that sustain waking brain performance. An alternative view proposes that …

Artificial night lighting rather than traffic noise affects the daily timing of dawn and dusk singing in common European songbirds

…, JM Samplonius, E Schlicht, M Valcu… - Behavioral …, 2014 - academic.oup.com
It is well established that artificial night lighting can influence animal orientation, but there is
less information about its effects on other behaviors. Previous work suggested that light …

Avian olfactory receptor gene repertoires: evidence for a well-developed sense of smell in birds?

SS Steiger, AE Fidler, M Valcu… - Proceedings of the …, 2008 - royalsocietypublishing.org
Among vertebrates, the sense of smell is mediated by olfactory receptors (ORs) expressed in
sensory neurons within the olfactory epithelium. Comparative genomic studies suggest that …

Light pollution alters the phenology of dawn and dusk singing in common European songbirds

A Da Silva, M Valcu… - … Transactions of the …, 2015 - royalsocietypublishing.org
Artificial night lighting is expanding globally, but its ecological consequences remain little
understood. Animals often use changes in day length as a cue to time seasonal behaviour. …

Skin telocytes

MC Rusu, N Mirancea, VS Mănoiu, M Vâlcu… - Annals of Anatomy …, 2012 - Elsevier
A distinctive stromal cell-type, the telocyte (TC), has recently been described to send
specific long prolongations (telopodes) alternating thin segments (podomers) with dilations (podoms…

Unexpected diversity in socially synchronized rhythms of shorebirds

M Bulla, M Valcu, AM Dokter, AG Dondua… - Nature, 2016 - nature.com
The behavioural rhythms of organisms are thought to be under strong selection, influenced
by the rhythmicity of the environment 1 , 2 , 3 , 4 . Such behavioural rhythms are well studied …

A global analysis of song frequency in passerines provides no support for the acoustic adaptation hypothesis but suggests a role for sexual selection

P Mikula, M Valcu, H Brumm, M Bulla… - Ecology …, 2021 - Wiley Online Library
Animals use acoustic signals for communication, implying that the properties of these signals
can be under strong selection. The acoustic adaptation hypothesis predicts that species in …

When the sun never sets: diverse activity rhythms under continuous daylight in free-living arctic-breeding birds

SS Steiger, M Valcu, K Spoelstra… - … of the Royal …, 2013 - royalsocietypublishing.org
Circadian clocks are centrally involved in the regulation of daily behavioural and
physiological processes. These clocks are synchronized to the 24 h day by external cues (Zeitgeber), …
