Adaptation of Pelage Color and Pigment Variations in Israeli Subterranean Blind Mole Rats, Spalax Ehrenbergi
BACKGROUND Concealing coloration in rodents is well established. However, only a few studies examined how soil color, pelage color, hair-melanin content, and genetics (i.e., the causal chain) synergize to configure it. This study investigates the causal chain of dorsal coloration in Israeli subterranean blind mole rats, Spalax ehrenbergi. METHODS We examined pelage coloration of 128 adult ani...
متن کاملVariations in ribosomal DNA and mitochondrial DNA among chromosomal species of subterranean mole rats.
Restriction site variations in nuclear ribosomal DNA (rDNA) spacers and mitochondrial DNA (mtDNA) were examined in several populations of mole rats with variable numbers of chromosomes, which represented the two superspecies Spalax leucodon (2n = 38, 54, or 62) and Spalax ehrenbergi (2n = 52, 54, 58, or 60). Sequence divergence of rDNA spacers between the members of the superspecies was approxi...
متن کاملOntogenetic expression of erythropoietin and hypoxia-inducible factor-1 alpha genes in subterranean blind mole rats.
Blind subterranean mole rats of the Spalax ehrenbergi superspecies in Israel have evolved multiple adaptive strategies to face underground hypoxia. Hypoxia-inducible factor-1alpha (HIF-1alpha) and erythropoietin (Epo) are key factors in the development of normal erythropoiesis and angiogenesis. Here, we demonstrate via real-time polymerase chain reaction (PCR) quantification that Spalax fetal l...
متن کاملBody Temperature Patterns and Rhythmicity in Free-Ranging Subterranean Damaraland Mole-Rats, Fukomys damarensis
Body temperature (T(b)) is an important physiological component that affects endotherms from the cellular to whole organism level, but measurements of T(b) in the field have been noticeably skewed towards heterothermic species and seasonal comparisons are largely lacking. Thus, we investigated patterns of T(b) patterns in a homeothermic, free-ranging small mammal, the Damaraland mole-rat (Fukom...
متن کاملSocial Structure Predicts Genital Morphology in African Mole-Rats
BACKGROUND African mole-rats (Bathyergidae, Rodentia) exhibit a wide range of social structures, from solitary to eusocial. We previously found a lack of sex differences in the external genitalia and morphology of the perineal muscles associated with the phallus in the eusocial naked mole-rat. This was quite surprising, as the external genitalia and perineal muscles are sexually dimorphic in al...
