ECOLOGY OF MENINGEAL WORM, PARELAPHOSTRONGLYUS TENIUS (NEMATODA) IN WHITE-TAILED DEER AND TERRESTRIAL GASTROPODS OF MICHIGAN'S UPPER PENINSULA WITH IMPLICAITONS FOR MOOSE
Moose (Alces alces) were reintroduced to Michigan's Upper Peninsula in the mid-1980's. Because of some of the subsequent mortalities were attributed to meningeal worm, Parelaphostrongylus tenuis, a study was done in 1995 - 1996 to determine potential exposure of moose to this parasite. Obj...

Moose (Alces alces) were reintroduced to Michigan's Upper Peninsula in the mid-1980's.
