Do Siberian Flying Squirrels reuse nest materials made by other individuals?

Ultrasonic Vocalizations Emitted by Flying Squirrels

Anecdotal reports of ultrasound use by flying squirrels have existed for decades, yet there has been little detailed analysis of their vocalizations. Here we demonstrate that two species of flying squirrel emit ultrasonic vocalizations. We recorded vocalizations from northern (Glaucomys sabrinus) and southern (G. volans) flying squirrels calling in both the laboratory and at a field site in cen...

Flying back to the nest

Stem cells are a critical component of most multicellular organisms as they are responsible for maintaining tissue turnover throughout the lifetime of the organism. This is such a fundamental mechanism of life that it is conserved from worms to humans. Loss of stem cells is associated with severe diseases and loss of stem cell function is at the heart of aging. Understanding the mechanisms resp...

Flying free before building my nest.

because of the poor employment prospects for biologists in Spain in the 1980s, which deterred me from studying science. But I had become fascinated by bearded vultures as a teenager, and my emotional attachment to these birds of prey and to conservation never faded. So, after fi nishing my bachelor’s degree, I signed a 6-month contract with the regional government to monitor bearded vulture bre...

Nest and nest-site reuse within and between breeding seasons by three neotropical flycatchers (Tyrannidae).

Nest and or nest site reuse within and between breeding seasons was reported by the Euler's Flycatcher (Lathrotriccus euleri), the Sepia-capped Flycatcher (Leptopogon amaurocephalus) and the Gray-hooded Flycatcher (Mionectes -rufiventris) in forest fragments from southeastern Brazil. Nest and or nest site reuse between some years was frequent within a single breeding season by the Sepia-capped ...
