genetic identification of mammalian carnivore species in the kushiro wetland, eastern hokkaido, japan, by analysis of fecal dna. | to identify mammalian carnivore species distributed in the kushiro wetland, eastern hokkaido, japan, we developed molecular-genetic methods for identification of the species from fecal samples collected from the field. species-specific primers and pcr programs were established for five native and six alien species of carnivores: martes zibellina, mustela nivalis, mustela erminea, vulpes vulpes, and nyctereutes procyonoides as native species, and neovison vison, martes melampus, mustela itatsi, c ... | 2008 | 18828658 |
interaction between seasonal density-dependence structures and length of the seasons explain the geographical structure of the dynamics of voles in hokkaido: an example of seasonal forcing. | the grey-sided vole (clethrionomys rufocanus) is distributed over the entire island of hokkaido, japan, across which it exhibits multi-annual density cycles in only parts of the island (the north-eastern part); in the remaining part of the island, only seasonal density changes occur. using annual sampling of 189 grey-sided vole populations, we deduced the geographical structure in their second-order density dependence. building upon our earlier suggestion, we deduce the seasonal density-dependen ... | 2002 | 12350246 |
