Species extinctions have defined the global biodiversity crisis, but extinction begins with
loss in abundance of individuals that can result in compositional and functional changes of …

Billions of nocturnally migrating birds move through increasingly photopolluted skies,
relying on cues for navigation and orientation that artificial light at night (ALAN) can impair. …

A fully automated method for the detection and quantification of bird migration was developed
for operational C-band weather radar, measuring bird density, speed and direction as a …

The effect of confinement on the dynamical properties of liquid water was studied by mid-infrared
ultrafast pump–probe spectroscopy on HDO:D 2 O in reverse micelles. By preparing …

Avian migration is one of Earth’s largest processes of biomass transport, involving billions of
birds. We estimated continental biomass flows of nocturnal avian migrants across the …

Many species of migratory birds have evolved the ability to migrate at night, and the recent
and rapid expansion of artificial light at night has markedly altered the nighttime sky through …

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 …

Climate warming challenges animals to advance their timing of reproduction [1], but many
animals appear to be unable to advance at the same rate as their food species [2, 3]. As a …

We study the vibrational dynamics of nanodroplets of liquid water with femtosecond two-color
midinfrared pump-probe spectroscopy. For the smallest nanodroplet, containing 10–15 …

Nocturnal avian migration flyways remain an elusive concept, as we have largely lacked
methods to map their full extent. We used the network of European weather radars to …
