Second Intermediate Host-Specificity Of Haematoloechus Complexus And Haematoloechus Medioplexus (Digenea: Haematoloechidae), Scott D. Snyder, John J. Janovy
Second Intermediate Host-Specificity Of Haematoloechus Complexus And Haematoloechus Medioplexus (Digenea: Haematoloechidae), Scott D. Snyder, John J. Janovy
Biology Faculty Publications
Second intermediate host-specificity was examined for two species of the frog lung fluke genus Haematoloechus. Nine species of freshwater arthropods were exposed to cercariae of H. complexus and H. medioplexus. Metacercariae of H. complexus developed in all arthropod species used. Metacercariae of H. medioplexus developed only in anisopteran odonate naiads. This difference in host utilization may have epizootiological implications. The potential development of H. complexus in a greater number of arthropods than H. medioplexus may increase the chances of ingestion of H. complexus by an anuran host. The range of arthropods parasitized by H. complexus indicates that host-specificity …
Students' Perception Of Teacher Expectation In A Co-Educational Physical Activity Class, Cari Robin Turner
Students' Perception Of Teacher Expectation In A Co-Educational Physical Activity Class, Cari Robin Turner
Student Work
The purpose of this study was to determine if a gender difference exists between students perception of male and female teacher expectation. Student perceptions were determined by administering the Student Perception Inventory (SPI) developed by McBride (1990). Three high schools and five junior high schools which included 15 teachers participated in the study. All students who participated were enrolled in co-educational physical activity classes. All students were surveyed at the beginning of the class period. There were 363 students surveyed. Of the 363 students surveyed, 342 were considered usable. Analysis of the data included frequency and percentage of response, as …
Nectar-Seeking Visits By Butterflies In A Tallgrass Prairie Remnant In Eastern Nebraska, Tanya Bray
Nectar-Seeking Visits By Butterflies In A Tallgrass Prairie Remnant In Eastern Nebraska, Tanya Bray
Biology Faculty Publications
Stolley Prairie, a tallgrass virgin prairie remnant in eastern Nebraska, was visited 20 times between May 25 and August 14, 1988. Fifty-two species offorbs were observed in bloom during this period. Twenty-seven species of butterflies were observed and 21 species made 262 nectar-seeking visits to 21 plant species. While numbers offorbs in bloom did not strongly correlate with numbers of butterflies present, peaks of butterfly occurrence appeared to follow peaks of blossom abundance. The number of plant species utilized by a species of butterfly ranged from one to nine. Plants with an abundance of nectar such as common milkweed and …
