Maximum Entropy Modeling of Indiana Bat (Myotis Sodalis) Maternity Roost Habitat
… variables associated with Indiana bat maternity roost trees in an attempt to better understand what factors play a role in their distribution in north central Missouri. I tracked reproductive female Indiana bats to 20 different primary and secondary roost trees; these are roosts that had multiple …

A Comparison of Summer and Winter Roosting Habitat and Behavior of Evening Bats (Nycticeius Humeralis) in Missouri
… 13 evening bats (Nycticeius humeralis) to 34 trees during the summer of 2003 and 11 evening bats to 29 trees during the winters of 2003 and 2004. I captured males in every month of the year and I provide capture and radio-telemetry evidence that females are also year-round residents of …

Bats and trees in a managed forest
… American bat species rely heavily on forests for roosting and foraging habitat. Especially in the face of drastic population declines, understanding how forests can be managed to support local bat assemblages is crucial for bat conservation. We worked in two managed hardwood state forests in …

Assessment Of Natural Roost Availability And Artificial Roost Preference By Indiana Bats In Scott County, Kentucky
In addition to using natural roosts, Indiana bats (Myotis sodalis) form maternity colonies in artificial roosts such as rocket boxes and bark-mimic structures. However, few Indiana bat study systems contain multiple artificial roost types alongside natural roosting options. I sought to analyze …

Nocturnal roost tree, roost site and landscape characteristics of Carnaby's Black-Cockatoo (Calyptorynchus latirostris) on the Swan Coastal Plain
There is limited information on communal roosting in parrot species of Western Australia and other parts of the world. Carnaby’s Black-Cockatoo is an endangered species that forms large nocturnal communal roosts, and for this reason they are an ideal model species to test the characteristics or …

Bald eagle habitat use on B. Everett Jordan Lake and Falls Lake, North Carolina
I examined the roosting and perching habitat preferences of a nonbreeding population of bald eagles in North Carolina during 1986 and 1987. I characterized roosting habitat at 2 scales; those of forest stands and individual roost trees. Eagles chose roost areas that were less dense, had less canopy …

Roosting Habitat and Poult Survival of Merriam's Turkeys in the Southern Black Hills of South Dakota
… main objectives of this project were to evaluate roosting habitat and poult survival of Merriam's turkeys in the southern Black Hills of South Dakota. Wild turkey females were captured during the winters of 2001 and 2002 and fitted with radiotransmitters to determine roost sites and assess poult …

Seasonal activity patterns of bats in the Central Appalachians
Two threats to bats are especially pervasive in the central Appalachian Mountains of the eastern United States: a fungal disease called White-nose Syndrome (WNS) and wind energy development. White-nose Syndrome has caused the death of millions of bats in North America, and multiple hibernating bat …

Assessment of Indiana bat reproductive condition, recapture trends, and temperatures of artificial roosts in Kentucky
… Mist net surveys around artificial maternity roosts at three focal management areas resulted in the capture of 866 Indiana bats across 22 netting events during the 2017-2019 maternity seasons. I examined changes in female mass (a measure of reproductive health) across years in order to …
