Ficoll density gradient sedimentation isolation of pelage hair follicle mesenchymal stem cells from adult mouse back skin: a novel method for hair follicle mesenchymal stem cells isolation [PDF]

open access: goldStem Cell Research & Therapy, 2022
Background Hair follicle mesenchymal stem cells (HF-MSCs) have great potential for cell therapy. Traditional method to isolate whisker HF-MSC is time-consuming and few in cell numbers.

«Pepper's patches» on Rangifer pelage

open access: diamondRangifer, 1986
We describe and give frequencies of occurrence of a rarely-mentioned pattern of spots in Rangifer pelage. We also show that the pattern was well-known to Palaeolithic humans who recorded it in their cave art.

Pelage color of red bats Lasiurus borealis varies with body size: An image analysis of museum specimens

open access: goldCurrent Zoology, 2010
Mammalian pelage color can vary among individuals of many species, although this intraspecific variation is often overlooked by researchers, perhaps because of its sometimes subtle nature and difficulty in assessing it quantitatively.

Seasonal pelage color change: news based on a South American Rodent [PDF]

open access: diamondAnais da Academia Brasileira de Ciências, 2006
Mammalian seasonalmolting and color change are known to be influencedby photoperiod changes. Calomys laucha, a South American rodent, exhibits seasonal pelage color change; however, unlike Northern hemisphere rodents, which present a gray or brown color ...

Extensive population genetic structure in the giraffe [PDF]

open access: yesBMC Biology, 2007
Background A central question in the evolutionary diversification of large, widespread, mobile mammals is how substantial differentiation can arise, particularly in the absence of topographic or habitat barriers to dispersal. All extant giraffes (Giraffa

Comparative histomorphometric and transcriptomic analysis reveals potential genetic determinants of pelage variation between hairy and coarse-woolly sheep [PDF]

open access: yesBMC Genomics
Background The unique pelage composition and developmental pattern endow hairy sheep with superior heat tolerance and minimized wool-shearing needs, compared with coarse-woolly sheep.

Sexual dichromatism in the fur of a bat: An exploration of color differences and potential signaling functions [PDF]

open access: yesEcology and Evolution
Sex differences in body color (i.e., sexual dichromatism) are rare in bats and, more broadly, in mammals. The eastern red bat (Lasiurus borealis) is a common tree‐roosting bat that occupies much of North America and has long been described as sexually ...

Pelage variation and morphometrics of closely related Callithrix marmoset species and their hybrids [PDF]

open access: yesBMC Ecology and Evolution
Background Hybrids are expected to show greater phenotypic variation than their parental species, yet how hybrid phenotype expression varies with genetic distances in closely-related parental species remains surprisingly understudied.

Total mercury in small mammals from forest ecosystems (nearby Cherepovets, Vologda region) [PDF]

open access: yesE3S Web of Conferences, 2023
The aim of the research is to determine the total mercury (THg) in small mammals in forest ecosystems at a distance of 3 – 8 km from the boundaries of the industrial site of PJSC Severstal near Cherepovets, Vologda region. THg in the pelage and organs of

Photoperiodic influences on ultradian rhythms of male Siberian hamsters. [PDF]

open access: yes, 2012
Seasonal changes in mammalian physiology and behavior are proximately controlled by the annual variation in day length. Long summer and short winter day lengths markedly alter the amplitude of endogenous circadian rhythms and may affect ultradian ...
