Kosterní zbytky v potravě kalouse ušatého Asio otus (Linnaeus,1758) jako ukazatele populačních změn drobných savců na zimovišti v Kladně-Kročehlavech / Telemetry of the Long eared owl (Asio otus) in the wintering place in Kladno

23/6/2011 Kosterní zbytky v potravě kalouse ušatého 7 jako ukazatele populačních změn drobných savců 1.2 Abstrakt v anglickém jazyce The diploma thesis is called Skeletal Remnants in Diet of Long-eared Owl Asio otus (Linnaeus, 1758) as The Indicators of Fluctuation in Size of Population of Small Mammals in Wintering Place in Kladno-Kročehlavy. The thesis deals with oversight of Long-eared Owl in his wintering site, analysis of his diet, and estimation of population changes in the diet of small vertebrate. It also consists of the estimation of changes in gender of small mammals and in the content of his diet, and of studies morphological traits done on pelvises of males and females of common vole. As part of didactic section there were laboratory exercises completed. The focus was on the analyses of pellets and the assignment of small vertebrates in the diet of Long-eared Owl. The main monitoring was completed in the period of autumn 2009 till the end of winter 2010. The results showed significant changes in the population of small mammals included in the diet of Long-eared Owl could bring new knowledge about population dynamics of small mammals. Another part of monitoring of population of Long-eared Owl was also tramping and ringing. Most of the materials used for this analysis of the diet came from the...

Habitat selection and roosting ranges of northern long-eared bats (Myotis septentrionalis) in an experimental hardwood forest system

Badin, Holly A. 03 May 2014 (has links)
This study presents the findings of a field study examining roost tree selection and roosting ranges of the northern long-eared bat (Myotis septentrionalis) in an experimental ecosystem of two southern Indiana state forests comprised of differing timber harvesting treatments. The northern long-eared bat is anticipated to be added to the Endangered Species list in the fall of 2014, so understanding its habitat selection is important to aid in minimizing their population decline. Northern long-eared bats were captured in Morgan-Monroe and Yellowwood state forests, and females were fitted with transmitters. We tracked these bats to their maternity roost trees during the day, and measured vegetation characteristics around those trees. Roost tree locations were plotted in ArcMap (ArcGIS 10.2) to find roosting ranges, and the roosting range size for this species was found to average 5.4 ha. Bats roosted in the unharvested forest more often than in trees within the harvested areas, and selected areas containing more vegetation obstruction, or clutter, in both areas. However, northern long-eared bats are roost generalists when compared to other species for many vegetative characteristics, and may tolerate smaller forest harvests as long as adequate roost trees remain available on the landscape. / Roost tree selection of the northern long-eared bat (Myotis septentrionalis) in southern Indiana -- Roosting ranges of the northern long-eared bat (Myotis septentrionalis) in southern Indiana. / Department of Biology
