Reproduction in the Wolverine, <i>Gulo guloi>

The reproductive habits of the wolverine, largest of the terrestrial mustelids, have remained largely unknown. Recently Rausch (1953) has concluded that the American and European wolverines belong to the same species (Gulo gulo). In this paper, the reproduction of this species is investigated.

<i>Paranoplocephala sciurii> (Cestoda: Anoplocephalidae), a Parasite of the Northern Flying Squirrel (<i>Glaucomys sabrinusi>), with a Discussion of Its Systematic Status

This study redescribes Andrya sciuri Rausch, 1947 (Anoplocephalidae) from the northern flying squirrel, Glaucomys sabrinus (Shaw), in North America, to redefine the morphology and generic position of this poorly known cestode. Andrya sciuri is shown to belong unambiguously to the genus Paranoplocephala Lühe, 1910 sensu Haukisalmi and Wickström (2005). Paranoplocephala sciuri is compared with four species that resemble it morphologically, and features that can be used in its identification are presented. It is suggested that P. sciuri has speciated through a shift from arvicoline rodents (voles and lemmings) to G. sabrinus.
