Squirrels in Cities: Meeting the Anthropological Conservation Conundrum of the World’s Squirrels
As occurrences and even entire populations of squirrels in cities, and especially around them, become increasingly more frequent, addressing this...

Who gets the treat: Interspecific interactions between red squirrels and corvids in an urban park
Squirrels and some corvids have successfully adapted to urban conditions. Their populations are often more abundant in city parks than in rural...

Seasonal variation in the activity pattern of red squirrels and their mammalian predators
Camera traps are a powerful tool to monitor the activity pattern of species over long time periods. Camera data can be used to analyze activity...

Trade in Prevost’s squirrels: legality, risk for introduction and disease transmission
Squirrels traded for pets or consumption have the potential to be vectors for zoonotic disease transmission and to establish themselves as invasive...

Circadian Activity in Yellow Ground Squirrels Spermophilus fulvus Licht. (Sciuridae): A Pilot Instrumental Study
AbstractMost of the information on animal circadian activity is based on laboratory data. To obtain information from a natural population, we...

Juvenile social play predicts docility in Belding’s ground squirrels
AbstractWe evaluated the hypothesis that social play behavior influences the development of temperament in young animals, using docility as a measure...

Urban eastern gray squirrels (sciurus carolinensis) show little seasonal variation in biochemical and hematological parameters
Urban wildlife faces unique physiological and behavioral challenges compared to conspecifics which live in less altered natural habitats. Animals in...

The advantage of living in the city: effects of urbanization on body size and mass of native and alien squirrels
In an ever more urbanized world, animals have to cope with different challenging conditions that may shape the individual’s phenotype in the urban...

The retrieval of food hoarded by red squirrels inhabiting an urban park
Food hoarding is a useful evolutionary adaptation which strongly affects animal fitness. However, its effectiveness depends on the trade-off between...

Gray squirrels consume anthropogenic food waste most often during winter
Urban habitats provide wildlife with predictable, easily accessible and abundant food sources in the form of human food waste. Urban eastern gray...

Evolution, Extinction, and Extinction Rate Estimates of the World Squirrels
Beyond Charles Darwnin, the taxonomy and subsequent phylogeny of squirrels, their biogeography, and their evolution explicit in time and space remain...

Seasonal activity patterns of sympatric eastern gray squirrels (Sciurus carolinensis) and fox squirrels (Sciurus niger) in a Midwestern metropolitan region
Niche partitioning reduces interspecific competition, facilitating coexistence. In urban ecosystems, however, habitat loss reduces species’ ability...

Differential bone remodeling mechanism in hindlimb unloaded and hibernating Daurian ground squirrels: a comparison between artificial and natural disuse within the same species
Loss of bone mass can occur in mammals after prolonged disuse but the situation for hibernators that are in a state of torpor for many months of the...

Plasticity changes in iron homeostasis in hibernating Daurian ground squirrels (Spermophilus dauricus) may counteract chronically inactive skeletal muscle atrophy
Disuse-induced muscular atrophy is frequently accompanied by iron overload. Hibernating animals are a natural animal model for resistance to disuse...

Sex-specific effects of capital resources on reproductive timing and success in red squirrels
AbstractReproduction is an energetically expensive activity for both sexes. However, if males and females differ in their annual timing of...

Winter habitat selection of Japanese squirrels in a snowy region of northeastern Japan
We clarified the landscape-scale habitat selection of Japanese squirrels during winter in heavy snowfall areas in northeastern Japan. In this study,...

Frontoparietal connectivity as a product of convergent evolution in rodents and primates: functional connectivity topologies in grey squirrels, rats, and marmosets
Robust frontoparietal connectivity is a defining feature of primate cortical organization. Whether mammals outside the primate order, such as...

First Conclusions, Success Stories, and A Good Calls-to-Action for the Conservation of the World’s Squirrels: From ‘Squirrelology’ and ‘Ministry of Squirrels’ to a ‘Global Squirrel Agenda’!
For the progression of science and society, it is essential to use the synthesized information and to present good ‘calls to action’ for the future....

Long-Term Dynamics of Spatial and Genetic Structure of a Narrow Hybrid Zone between Russet (Spermophilus major Pallas, 1778) and Yellow (Spermophilus fulvus Lichtenstein, 1823) Ground Squirrels
AbstractThe research into the structure, population and genetic patterns of formation and long-term existence of natural hybrid zones is of paramount...

Taxonomy for the Squirrels of the World: Hairy Classifications and Conservation Category Games
This chapter represents an overview list of all the extant squirrel species with the illustrated discrepancies between the number of accepted species...
