We answer a question of László Babai concerning the abelian sandpile model. Given a graph, the model yields a finite abelian group of recurrent configurations which is closely related to the combinatorial Laplacian of the graph. We explicitly describe the group elements and operations in the case of thick trees with loops—that is, graphs which are obtained from trees by setting arbitrary edge m...

storage and circadian rhythms. Memory and learning have been studied in squirrels that cache their food, sometimes not returning until the next year. Singing mice provide a new model for studying speech and learning. Studies of wild rodents will undoubtedly give us a window into the genetics underlying phenotypic variation, further promoted by genome sequencing projects that extend beyond the u...

altogether, 132 rodents of 4 species of meriones persicus , cricetulus migratorius, mus muscri~ius and allactaga dater were collected with live traps from different parts of meshkin - shahr district from summer 1373 to autumn 1374. the purpose of this survey was to identify the parasitic fauna of rodents. before dissection, the mammals were measured for biometric purposes. babesia microti , see...

iranian jerboa classified as data deficient species according to the iucn red list. little information has been published about ecological and biological characteristics of allactaga firouzi and other members of genus allactaga. in the present study, we aimed to identify some ecological characteristics, such as: hibernation, feeding habits, breeding, coexistence with other rodents and threateni...

Problem statement: The digestive tract of animals including rodents has taxonomic and ecologic importance due to its ability in adaptation for different environments. Whereas colon absorbs water and carbohydrates, it has a vital role ecologically and physiologically and enjoys different histological structures in different rodents with various diets. Approach: Different rodent specimens belong ...

Entomoparasitic nematodes are natural control agents for many insect pests, including fleas that transmit Yersinia pestis, a causative agent of plague, in the natural foci of this extremely dangerous zoonosis. We examined the flea samples from the Volga-Ural natural focus of plague for their infestation with nematodes. Among the six flea species feeding on different rodent hosts (Citellus pygma...
