| evolution, climatic change and species boundaries: perspectives from tracing lemmiscus curtatus populations through time and space. | to provide empirical evidence of species boundaries and the role of climatic change in affecting evolution, we documented evolution of the sagebrush vole, lemmiscus curtatus, through hundreds of thousands of years by following populations from the middle pleistocene to the present. we found that: (i) extant representatives of the species culminate a morphological transition that was initiated within an unusually arid and warm interglacial period, perhaps related to the shift from glacial-intergl ... | 2003 | 14728781 |
| paranoplocephala maseri n. sp. (cestoda, anoplocephalidae), a parasite of sagebrush voles lemmiscus curtatus (rodentia) in the usa. | paranoplocephala maseri n. sp. is described from lemmiscus curtatus (cope) in the usa. the new species is related to paranoplocephala omphalodes (hermann, 1783), p. caucasica (kirschenblat, 1938), p. kirbyi voge 1948, p. microti (hansen, 1947) and p. macrocephala (douthitt, 1915) sensu genov et al. (1996). p. maseri n. sp. differs from p. omphalodes in the position of the genital pores, testes and cirrus-sac; from p. caucasica, in which there is an unarmed cirrus, in both the distribution and la ... | 1999 | 10612439 |
