BAT DIVERSITY, ACTIVITY, AND HABITAT USE IN A MIXED DISTURBANCE LANDSCAPE

Book Description
Bat species face multiple threats. One such threat, white-nose syndrome (WNS) has drastically reduced many bat populations. Also, habitat loss and fragmentation often forces bats to concentrate in remnant natural areas, or utilize habitats that are not as suitable. Both of these threats, while threaten bats in a general sense, also affect species differentially. The Oak Openings Region of Northwest Ohio is a biodiversity hotspot with a landscape composed of remnant natural areas within a matrix of agriculture and urban areas. This area, which provides crucial summer foraging habitat, has experienced declines in bat activity, shifts in bat assemblages, and some in diversity, in recent years, especially since WNS introduction. To study bats in this diverse landscape, we sampled bats acoustically from May - August 2016. We sampled mobile transects along roads along with stationary sites within the Oak Openings Preserve within the region. We identified calls to species and ran analyses investigating total bat activity, species-specific activity and presence, and bat diversity compared to. We compared bats to environmental, vegetation, road, and landcover parameters. Our results show that certain parameters influence bats as a whole, while others only affect one or a few species. We found that savanna stationary sites had more species-specific activity and bat diversity than forested sites (Rank Sums, p

Bats in the Anthropocene: Conservation of Bats in a Changing World
Author: Christian C. VoigtPublisher: Springer
ISBN: 3319252208
Category : Nature
Languages : en
Pages : 601
Book Description
This book focuses on central themes related to the conservation of bats. It details their response to land-use change and management practices, intensified urbanization and roost disturbance and loss. Increasing interactions between humans and bats as a result of hunting, disease relationships, occupation of human dwellings, and conflict over fruit crops are explored in depth. Finally, contributors highlight the roles that taxonomy, conservation networks and conservation psychology have to play in conserving this imperilled but vital taxon. With over 1300 species, bats are the second largest order of mammals, yet as the Anthropocene dawns, bat populations around the world are in decline. Greater understanding of the anthropogenic drivers of this decline and exploration of possible mitigation measures are urgently needed if we are to retain global bat diversity in the coming decades. This book brings together teams of international experts to provide a global review of current understanding and recommend directions for future research and mitigation.

Book Description
Landscape anthropization through habitat loss and fragmentation is one of the main threats to biodiversity. This PhD (CIFRE funding) was carried out in at INRAE Toulouse (Dynafor lab) in collaboration with the Conservatoire des Espaces Naturels de Midi-Pyrénées (CENMP). It aimed at a better understanding of the impacts of light pollution and road expansion on bats, two major and inevitable elements of anthropization, using a landscape ecology framework applied to bat conservation. This work is structured in 4 sections: (i) by means of an exhaustive review of bat telemetry studies in Europe and North America, I explored how landscape anthropization influenced bat mobility through mean home range sizes and commuting distances; (ii) using simultaneous acoustic sampling of bat communities at both edge and interior forest patches in 172 landscapes varying in terms of forest amount and road density, I analyzed how forest fragmentation and road network shaped the taxonomic, functional and phylogenetic diversity of bat communities at multiple spatial scales; (iii) by developing models of species distribution and connectivity (least-cost path) at the scale of a large urban area, I assessed the effect of different street lighting extinction scenarios on landscape connectivity for three bat species; and (iv) using a field experiment, I tested the influence of landscape context around road underpasses on their use by bats and the efficiency of these structures in maintaining landscape connectivity while reducing the risk of collision with vehicles. While the first two sections of the PhD seek to better understand the mechanisms underlying the effects of landscape anthropization on bats, the last two axes are applied to their direct conservation by demonstrating how landscape ecology can contribute to improve existing measures.
