Caudal Polymorphism And Cephalic Morphology Among First-Stage Larvae Of Parelaphostrongylus Odocoilei (Protostrongylidae: Elaphostrongylinae) In Dall’S Sheep From The Mackenzie Mountains, Canada, Eric P.

We demonstrate polymorphism in the structure of the tail among first-stage larvae of Parelaphostrongylus odocoilei (Protostrongylidae). Two distinct larvae, both with a characteristic dorsal spine, include (1) a morphotype with a kinked conical tail marked by three distinct transverse folds or joints and a symmetrical terminal tail spike and (2) a morphotype with a digitate terminal region lacking folds or joints and with an asymmetrical, subterminal tail spike. These divergent larval forms had been postulated as perhaps representing distinct species of elaphostrongyline nematodes. Application of a multilocus approach using ITS-2 sequences from the nuclear genome and COX-II sequences from the …


Possible Recent Range Expansion Of Alcataenia Longicervica (Eucestoda: Dilepididae) Parasitic In Murres Uria Spp. (Alcidae) Into The North Atlantic [Short Communications], Sabir B. Muzaffar, Eric P. Hoberg, Ian L. Jones Jan 2005

Possible Recent Range Expansion Of Alcataenia Longicervica (Eucestoda: Dilepididae) Parasitic In Murres Uria Spp. (Alcidae) Into The North Atlantic [Short Communications], Sabir B. Muzaffar, Eric P. Hoberg, Ian L. Jones

Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications

A wide range of helminths has been recorded from murres Uria spp. (Threlfall 1971, reviewed by Hoberg 1984a, Muzaffar & Jones 2004). Of the cyclophyllidean cestodes that parasitize murres, the genus Alcataenia Spasskaya 1971 (Dilepididae) is represented by ten species, eight of which are restricted and specific to the auks; the other two species occur in gulls (Laridae). The intermediate hosts of Alcataenia are euphausiid crustaceans such as species of Thysanoessa (Shimazu 1975), which also form an important dietary component of breeding and wintering murres, particularly Thick-billed Murres Uria lomvia (Gaston & Noble 1985, Birkhead & Nettleship 1987, Elliot et …


First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles Jan 2005

First Record Of An Adult Male Evening Bat From Kansas, Clay R. Davis, Justin G. Boyles

The Prairie Naturalist

The evening bat (Nycticeius humeralis) occurs throughout the eastern and southeastern United States and into extreme northeastern Mexico, approximately 42° to 18° N latitude (Watkins and Shump 1981). Although records of females are common, records of adult male evening bats are rare in the northern portion of the species range (Watkins 1969, Watkins 1972). Jones et al. (1967) suggested that adult males might not accompany females to at least some parts of the parturient range. As part of a larger study (Davis 2003) we surveyed bats on Fort Leavenworth Military Reservation (FLMR), Leavenworth County, Kansas in July 2002 …
