On the winter enhancement of adaptive humoral immunity: hypothesis testing in desert hamsters (Phodopus roborovskii: Cricetidae, Rodentia) kept under long-day and short-day photoperiod

Publikováno v: Integrative zoologyREFERENCES. 15(3)

We tested the winter immunity enhancement hypothesis (WIEH) on male desert hamsters (Phodopus roborovskii) kept under long-day (LD) and short-day (SD) photoperiods. We assumed that under SD in a laboratory, the adaptive humoral immune responsiveness

Publikováno v: Mammalian Biology. 81:255-265

Alarm calls of ground squirrels are innate signals, showing substantial geographical variation across populations without the masking effects of sex and age- related variation. This makes them a convenient model for studying population genetic effect

[Female mate choice, male-male competition, and male sexual traits: Experimental study of sexual selection directedness in Campbell's dwarf hamster (Phodopus campbelli Thomas 1905)]

Autor: N Yu, Vasilieva, O N, Shekarova, A M, Khrushchova, K A, Rogovin

Publikováno v: Zhurnal obshchei biologii. 78(2)

We studied the relationship between female mate choice and male-male competition in Campbell's dwarf hamster. Sexually motivated (SM) females chose between two tethered male siblings that differed in expression of sexual traits. Males were unrelated

Immunocompetence and reproductive characteristics of Campbell’s dwarf hamster males selected for low and high humoral immune response on sheep red blood cells (SRBC): Testing the immunocompetence handicap hypothesis

Autor: K. A. Rogovin, O. N. Shekarova, A.V. Bushuev, N. Yu. Vasilieva, A. M. Khrushcheva, O. V. Sokolova

Publikováno v: Biology Bulletin Reviews. 5:249-258

Characteristics of innate (nonspecific) and acquired T-cell immunity, resting metabolic rate, hormonal and reproductive status, morphological traits of maturation and aggressive behavior were studied in two sample groups of Campbell’s dwarf hamster

Effects of mitochondria-targeted plastoquinone derivative antioxidant (SkQ1) on demography of free-breeding Campbell dwarf hamsters (Phodopus campbelli) kept in outdoor conditions. Reproduction and lifespan: Explanation in the framework of ultimate loads

We studied demographic effects of the mitochondria-targeted antioxidant SkQ1 on free-breeding Campbell dwarf hamsters (Phodopus campbelli, Thomas, 1905, Rodentia, Cricetidae) in an outdoor vivarium with seasonally varying day length and temperatures.

Mitochondria-targeted antioxidant SkQ1 accelerates maturation in Campbell dwarf hamsters (Phodopus campbelli)

Autor: Vasily N. Manskikh, N. Yu. Vasilieva, A. M. Khrushcheva, O. N. Shekarova, K. A. Rogovin, M. V. Ushakova

Publikováno v: Biochemistry (Moscow). 79:1111-1116

We tested two hypotheses. 1) SkQ1 positively affects postnatal development of hamsters in litters born to parents receiving long-term SkQ1 treatment. 2) SkQ1 accelerates maturation of juvenile females receiving the antioxidant treatment from 10 days

The possibility of estimating the reproductive status of males using computer analysis of the contours of testes and midventral gland (MVG) in digital images was tested in Campbell’s dwarf hamsters (Phodopus campbelli). Relationships between the an
