متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
The divergence of major histocompatibility complex class I genes in Sciurus aberti.
Major histocompatibility complex (MHC) class I genes encode cell surface molecules that bind and present immunogenic peptides to cytolytic T lymphocytes. We have developed a model using the MHC (Scab) of tassel-eared squirrels, Sciurus aberti, to investigate the evolution of MHC genes in subspecies that have been effectively isolated in comparable, if not identical, environments. Class I cDNAs ...
متن کاملMechanisms of Cache Decision Making in Fox Squirrels (sciurus Niger)
The cache decisions of scatter-hoarding animals are influenced by a number of factors, including satiety, food quality, number of competitors, and the risk of predation and pilferage. However, it is unknown how animals assess these variables. We investigated this process experimentally in free-ranging fox squirrels (Sciurus niger) by measuring the effects of nut characteristics and social conte...
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...
