Book excerpt: This study presents the findings of a habitat suitability model for the northern long-eared bat maternity roosting habitat (Myotis septentrionalis) in a three-county region in southern Indiana. The northern long-eared bat was added to the endangered species list in 2015 and understanding its' habitat selection at the landscape scale is important to aid in minimizing population declines. Female northern long-eared bats were captured and fitted with transmitters in Morgan Monroe and Yellowwood state forests during the 2012-2015 summer maternity season. These bats were tracked to day roosts where location and habitat information was recorded. We used ArcMap to plot roost tree locations and extract landscape-level environmental variables. MaxEnt was used to evaluate which environmental variables of interest were of greatest importance to northern long-eared bats in our study. Our final model included a map indicating areas most suitable to northern long-eared bats. Our model indicated that elevation, distance to roads, and distance to regeneration openings had the most influence on which habitats bats used for roosting.

Book excerpt: Delineating habitat preferences, especially those of imperiled species, is critical to ensure that species have access to resources needed to persist. In addition to overall preferences, establishing the phenology of sensitive periods such as reproduction can be challenging for small, cryptic species such as bats. We conducted an empirical study in northeast Wyoming, USA, to characterize the habitat selection of northern long-eared bats (Myotis septentrionalis). Objectives in Chapter 1 were to (1) characterize the maternity roost-site preferences of endangered northern long-eared bats in a peripheral population occurring within a forest managed for timber harvest, and (2) determine whether roost-site preferences and switching were modulated by weather conditions. Chapter 2 objectives were (1) to assess whether maternity roost trees of northern long-eared bats are used for multiple years in northeast Wyoming; (2) to determine whether intra-seasonal occupation of maternity roosts in northeast Wyoming matches the timing of seasonal protections for northern long-eared bats; and (3) to assess the efficacy of motion-triggered game cameras for determining occupancy of maternity roosts. In our first chapter, we found that bats were more likely to select quaking aspens, snags, and trees relatively large in diameter; however, these preferences were modulated by daily weather conditions and reproductive state. Bats roosted more often in pine at warm temperatures and while lactating, and in snags when solar radiation was high and precipitation low. Bats preferred forest patches with higher canopy cover and a larger proportion of snags. In our second chapter, we documented colony occupation at maternity roosts across multiple years and outside of the protected season of June—July. We also recorded rarely documented behaviors, including pup carrying, with motion-triggered game cameras. Our findings provide guidance on habitat types that would be beneficial to conserve for northern long-eared bat populations, and more broadly, that context-dependence is an important consideration for habitat-selection studies. Peripheral populations may be critical for future recovery of declining species; however, seasonal protections against habitat disturbance may be mismatched with the phenology of populations at range edges.

This book was released on 2020 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: The decline in northern myotis (Myotis septentrionalis) populations since the arrival of white-nose syndrome (WNS) in eastern North America has led to the species receiving protected status in the United States and Canada. Much of the research on habitat use of this species has occurred during the summer maternity season while similar examinations of autumn and winter habits are scarce. The goal of my thesis was to describe the seasonal presence and habitat use of a remnant colony of northern myotis in central Pennsylvania. From 2017–2020, I radio-tagged 27 northern myotis and used acoustic bat detectors at 5 locations to study roost habitat choice and seasonal changes in activity. Radio-tagged northern myotis never left the study area and were tracked to day roosts until early November. Counts of bats exiting roost trees revealed that maternity roosts were as frequently used during autumn (August 15–October 31) as during summer (21 June–August 14). Similarly, 78% of roost trees located during autumn were used during the summer as well. Using model selection and multinomial logistic regression models, I found that tree decay stage, basal area of the forest stand, and distance to water best described the variance in male roosts, female roosts, and randomly sampled trees. Both male and female northern myotis preferred to roost in dead and declining trees. Females also preferred to roost in dense forest stands and in trees located close to water. During October and November, one radio-tagged female and one male northern myotis were tracked to a ground-level rock crevice. Acoustic activity recorded between February and October at this location differed from trends in activity at other sampling locations and had a peak of activity in late summer when northern myotis are known to swarm. Northern myotis calls were recorded at this roost between March and October and bats were observed emerging from this roost during spring and autumn but not summer. These data support the growing evidence that northern myotis hibernate outside of caves and show that bats in central Pennsylvania roost in maternity trees until at least late October.

Download or read book Bat Roosts in Trees written by Bat Tree Habitat Key and published by Pelagic Publishing Ltd. This book was released on 2018-11-19 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a guide to finding tree-roosts. It is the result of the collaborative efforts of professional surveyors and amateur naturalists across Europe as part of the Bat Tree Habitat Key project, and represents a combination of firsts: It is the first time legislation and planning policy have been reviewed and put to practical use to define an analysis framework with clearly identifiable thresholds for action. Yet, despite its efficacy in a professional context, it is also the first time a guide has been produced that is equally effective in achieving its objective for amateurs. It is the first time such a method has been evidence-supported throughout, with summary reviews of each aspect of the roosting ecology of the individual 14 tree-roosting species, with illustrative photographs and data to which the reader has open access. It is the first time a repeatable analysis framework has been defined against which the surveyor may compare their results at every stage, from the desk-study, through ground-truthing, survey and analysis, thereby ensuring nothing is overlooked and that every result can be objectively compared. The survey and analysis framework itself is ground-breaking in that it may readily be adapted for any taxa; from moths, through amphibians, reptiles, birds and all other mammals. Used diligently, these methods will reward disproportionately and imbue the reader with renewed confidence as they quickly progress from beginner to competency. Thus, this book is for everyone who has ever wanted to find a tree-roost, or to safeguard against inadvertently damaging one.
Book Synopsis Roost Site Selection by Indiana Bats (Myotis Sodalis) and Comparison of Foraging Habitat Selection by Morphologically Similar Bat Species in Bottomland Hardwood Ecosystems by : Jacquelyn A. Dearborn
Download or read book Roost Site Selection by Indiana Bats (Myotis Sodalis) and Comparison of Foraging Habitat Selection by Morphologically Similar Bat Species in Bottomland Hardwood Ecosystems written by Jacquelyn A. Dearborn and published by . This book was released on 2017 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: While bottomland hardwoods used to encompass a large portion of the south-central United States, due to clear cutting for agriculture and other purposes, the amount of bottomland hardwoods present has been reduced by almost 88 percent from its previous extent. At the same time, bat surveys in the Midwest after the arrival of white-nose syndrome (WNS) have shown declines in populations of Indiana bats (Myotis sodalis), northern long-eared bats (Myotis septentrionalis), little brown bats (Myotis lucifigus), and tri-colored bats (Perimyotis subflavus). Due to these threats to bat populations, it is important to gain information on how various bat species in the Midwest United States utilize the landscape within bottomland hardwood ecosystems in order to inform conservation efforts. There were two main objectives to this study. First, we sought to determine which roost site characteristics influence selection of a roost location by individuals in maternity colonies of Indiana bats. Second, we wanted to evaluate which habitat characteristics influenced occupancy of morphologically similar species within bottomland hardwood ecosystems in the Midwest United States: Myotis species, tri-colored bats, and evening bats (Nycticeius humeralis).

Waldien and published by . This book was released on 1998 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Management of habitat for bats requires sound information on their habitat requirements. I used radio telemetry to identify 80 roosts for 24 long-eared myotis (Myotis evotis); 74 roosts were identified for 21 females and 6 roosts for 3 males. Females primarily used dead and defective conifer trees (n=22) and conifer stumps (n=41) though they also used 3 live conifer trees, 1 live and 5 dead hardwood trees, and 2 conifer logs. Males used one each of the following structures: dead conifer, dead hardwood, conifer log, conifer stump, slash pile, and rock crevice. Female long-eared myotis primarily roosted in conifer stumps in landscapes dominated by younger forests and used dead or defective conifer trees and stumps in landscapes characterized by older forests. Roosts generally were located in upland habitats. Odds of a dead or defective conifer being used as a roosts was associated with decay class, presence of snags, and distance to the edge of the stand. Odds of a conifer stump being used was associated with amount of species of stump, height of the stump on the downhill side, access, woody debris within 1 m, and slope (%). Twelve female long-eared myotis were tracked on 23 nights to determine activity areas. Individuals had a mean nightly activity area of 39.5 ha which was centered 0.550 km from the day-roost and 0.16 km from available water; the maximum distance a bat was detected from a day-roost was 2.4 km. Odds of an area being used as an activity area was associated with distance to available water and percent of older forest conditions. Individual bats used the same general foraging area on different nights, suggesting that there are landscape features that function as centers of bat activity. Management of habitats for bats should consider spatial relationships of day-roosts and activity areas. Maintenance of large dead and defective conifers within 1 km of available water should provide roosting and foraging habitat for long-eared myotis and other species of bats. Leaving tall stumps also may provide structures for roosting.
