Speciation in Allopatric Species of the Hamster Subfamily Cricetinae (Rodentia, Cricetidae) [PDF]

open access: possibleBiology Bulletin Reviews, 2019
Abstract—According to the Dobzhansky–Muller model (Dobzhansky, 1937; Muller, 1942), in the absence of gene flow, conspecific populations can become reproductively isolated, and postzygotic isolation should increase proportionally to the square of divergence time.

Daily torpor in hamsters (Rodentia, Cricetinae)

Russian Journal of Ecology, 2012
Study of ecological adaptations, including torpor, related to survival through the adverse conditions of the autumn-winter season is important for both the estimation of the body reserves in mammals in general and the search for the ways to increase the cold-stress resistance in humans. The changes in the body temperature during the period from October

Experimental Comparative Analysis of Hunting Behavior in Four Species of Cricetinae Hamsters [PDF]

open access: possibleBiology Bulletin, 2019
In laboratory experiments we investigate hunting behavior towards insects in Phodopus sungorus (Pallas 1773), P. сampbelli (Thomas 1905), Allocricetulus eversmanni (Brandt 1859), and A. curtatus (Allen 1925). In these species purposeful inter-relations with insects in the predator–prey manner have been revealed and described in details.

Eubrachylaelaps martini, a New Mite (Acarina: Laelaptinae) from the Volcano Mouse (Mammalia: Cricetinae)

open access: closedThe Journal of Parasitology, 1951
Two collections of laelaptid mites from Mexico belong to an unnamed species of Eubrachylaelaps Ewing. This species is parasitic on the volcano mouse, Neotomodon alstoni Merriam, a member of the subfamily CRICETINAE to which belong all other hosts of the known species of Eubrachylaelaps. Through the kindness of Dr.

Experiments on nest-building behaviour in Peromyscus (Rodentia: Cricetinae)

open access: closedAnimal Behaviour, 1970
Abstract Previous studies reflect conflicting views on the relative importance of major climatic factors and microhabitat in selection for nest-building behaviour in the genus Peromyscus. In my study, populations of the leucopus species group (P. leucopus and P. gossypinus) from Illinois, Mississippi, and Florida were found not to differ consistently.

Speciation of Eversmann and Mongolian hamsters (Allocricetulus, Cricetinae): Experimental hybridization

Biology Bulletin, 2016
Contrary to the pre-existing concepts based on morphological and karyological data on the impossibility of hybridization between hamster species of the genus Allocricetulus (A. curtatus and A. eversmanni), F1 hybrids in both combinations, and backcrosses, were obtained for the first time.
