The Physiological Effects Of Strychnine And Electric Stimuli On Cyclops, Ralph J. Fricke
The Physiological Effects Of Strychnine And Electric Stimuli On Cyclops, Ralph J. Fricke
Journal of the Minnesota Academy of Science
Cyclops, the intermediate hosts of parasites of higher animal~, particularly some tapeworms of fish, waterfowl, and some mammals is a comparatively simply crustacean. From the following it should become apparent that the Cyclops is, in fact, very complex, exhibiting physiological reactions similar to those produced in the mammal. This study will include certain observations of the physiological effects of strychnine and electric stimuli on Cyclops. The animal lacks a heart. Body fluid is circulated as a result of the rhythmic movements of its gut. For the experiments a clone of the species Eueyclops agilis was established. In a clone, all …
An Investigation Of Possible Commensalism In Red Squirrels, Yellow-Bellied Sapsuckers, And Humming-Birds At The Lake Itasca Biological Station, John C. Coulter
An Investigation Of Possible Commensalism In Red Squirrels, Yellow-Bellied Sapsuckers, And Humming-Birds At The Lake Itasca Biological Station, John C. Coulter
Journal of the Minnesota Academy of Science
This is an investigation of a relationship noted at the Lake Itasca Biological Station. It was noted that the Red Squirrel, Tamiasciurus hudsonicus, in some locations spent a considerable amount of time lapping sap from the rows of holes drilled in the White Birch, Betula papyrifera, by the Yellow-bellied Sapsuckers, Sphyropious varius varius (L.). After the invasion of the red squirrel the sapsuckers and the Ruby-throated Hummingbird, Archilochus colubris (L.) continued to utilize the same food supply as well as a considerably number of insects. The two general objectives of this endeavor were then to investigate some of the related …
