Bat Habitat Use And Roost Tree Selection For Northern Long-Eared Myotis (Myotis Septentrionalis) In North-Central Ohio, Timothy J. Krynak
Bat Habitat Use And Roost Tree Selection For Northern Long-Eared Myotis (Myotis Septentrionalis) In North-Central Ohio, Timothy J. Krynak
Masters Theses
Understanding roosting behavior and habitat use of bats is an important component when unraveling life histories and their ecology. Ohio remains under-represented in published information of bats compared to surrounding states. This large scale survey in 2002–2003 and Myotis septentrionalis radio telemetry study in 2005 is one of the few conducted within the state and is the first in Ohio’s North-Central region. It is also the first study conducted where net sites were chosen randomly and spatially distributed to adequately survey bat populations within Cuyahoga Valley National Park and Cleveland Metroparks. This survey documented seven species (n = 668), with …
The Capacity Of Diatom Species To Survive Ingestion By The Algivorous Minnow, Pimephales Notatus, Paul Gregory Grubach
The Capacity Of Diatom Species To Survive Ingestion By The Algivorous Minnow, Pimephales Notatus, Paul Gregory Grubach
Masters Theses
The capacity of diatom species to survive gastrointestinal passage through the algivorous minnows Pimephales notatusand Campostoma anomalum was studied. From a site on the Grand River in northeastern Ohio, 27 minnows and 7 epilithic diatom samples were taken. In order to determine whether diatom taxa varied in digestibility, live/dead ratios of diatom cells taken from the minnows’ feces were compared with live/dead ratios of cells taken from immersed rocks. Diatoms that were live/undigested at the time of collection were differentiated from dead/digested cells under light microscopy by noting the presence of chloroplasts and/or lipid droplets. Seventy-seven percent of the …
