Basal rate of metabolism (BMR) and resting maternal rate of metabolism around peak lactation (RMR(L)) were measured in Crocidura russula, Mus domesticus and Microtus arvalis. These species have a moderate or high BMR relative to the scaling relationship of Kleiber. One goal of the study was to check whether females of these species show elevated rates of metabolism during lactation. A second go...

We sequenced 998 base pairs (bp) of mitochondrial DNA cytochrome b and 799 bp of nuclear gene BRCA1 in the Lesser white-toothed shrew (Crocidura suaveolens group) over its geographic range from Portugal to Japan. The aims of the study were to identify the main clades within the group and respective refugia resulting from Pleistocene glaciations. Analyses revealed the Asian lesser white-toothed ...

Mammalian herbivores, particularly dietary specialists must have an efficient means to metabolize the high doses of plant secondary compounds they consume. We found previously that Neotoma stephensi, a juniper specialist, upregulated catechol-O-methyl transferase (COMT) mRNA almost seven fold in response to an ecologically relevant diet (70% juniper). To further investigate the relevance of thi...

A total of 1,498 small mammals (rodents and insectivores), including Apodemus agrarius (n = 1,366), Crocidura lasiura (54), Mus musculus (32), Micronytus fortis (28), Eothenomys regulus (9), Micronys minutes (6), and Cricetulus triton (3), were live-trapped in Gyeonggi-do (Province) (Paju-si, Pocheon-gun, and Yeoncheon-gun) near the demilitarized zone (DMZ) from December 2004 to September 2005....

Repeated sea-level fluctuations during and prior to the Pleistocene had a dramatic effect on the distribution of land and connection among islands between the Asian and Australian continents. These cycles of connection and isolation have long been recognized as an important factor determining the distribution and organization of biodiversity in the Philippines. However, surprisingly few studies...
