Foraging and feeding behavior of the Eastern Grey Squirrel (Sciurus carolinensis)
The eastern grey squirrel (Sciurus carolinensis) is a prime example of scatter hoarding behavior, storing food in small hoards underground. Our research aimed to see how the spatial distribution of food affects the foraging behaviors of S. carolinensis, which is something that has not previously been researched. The experiments lasted from April May 2013 on the University of Maryland, College P...
متن کاملDetection of squirrel poxvirus by nested and real-time PCR from red (Sciurus vulgaris) and grey (Sciurus carolinensis) squirrels
BACKGROUND Squirrel poxvirus (SQPV) is highly pathogenic to red squirrels (Sciurus vulgaris), and is a significant contributing factor to the local extinction of the species in most parts of England and Wales, where infection is endemic in Eastern grey squirrel (Sciurus carolinensis) populations. Although a nested PCR assay has been used successfully to study the epidemiology of SQPV, samples h...

متن کاملFeeding of grey squirrels (Sciurus carolinensis) with the contraceptive agent DiazaCon™: effect on cholesterol, hematology, and blood chemistry.
Grey squirrels (Sciurus carolinensis) are an invasive species in Britain and Italy. They have replaced native red squirrels (Sciurus vulgaris) throughout most of Britain, and cause damage to trees. Currently, lethal control is used to manage grey squirrel populations in Britain, but nonlethal methods might be more acceptable to the public. One such method is contraception with 20,25-diazacholes...
متن کاملPre-dispersal strategies by Quercus schottkyana to mitigate the effects of weevil infestation of acorns
We investigated how pre-dispersal strategies may mitigate the effects of weevil infestation of acorns in a population of Quercus schottkyana, a dominant oak in Asian evergreen broad-leaved forests, and assess if weevil infestation contributes to low seedling recruitment. We counted the number of acorns produced, daily from the end of August to mid-late November for 9 years from 2006-2014. We al...
