Humaninduced species losses are currently responsible for the sixth mass extinction. Like many other organisms, populations of bats are threatened by various human activities (O’Shea et al. 2016). Given their lifehistory strategies with low mortality and slow reproductive rates, bat populations are particularly vulnerable when exposed to mass mortality events caused by unfavourable environmental conditions, anthropogenic threats, and diseases (O’Shea et al. 2016). Limited research effort has… Expand

Figures and Tables from this paper

Differences in seasonal survival suggest species‐specific reactions to climate change in two sympatric bat species
TLDR
Seasonal survival differences in Natterer's bats and Daubenton's bats are explored, pointing toward a high importance of specific time periods for population dynamics and suggests species‐, population‐, and age class‐specific responses to global climate change. Expand
Ecology and impacts of white-nose syndrome on bats
TLDR
Collectively, this research highlights how early pathogen detection and quantification of host impacts has accelerated the understanding of this newly emerging infectious disease. Expand
Determinants of defence strategies of a hibernating European bat species towards the fungal pathogen Pseudogymnoascus destructans.
TLDR
It is concluded that M. myotis, and possibly also other European bat species, tolerate Pd infections during torpor by using selected acute phase response parameters at baseline levels, yet without arousing from torpor and without synthesizing additional immune molecules. Expand
Population genetics as a tool to elucidate pathogen reservoirs: Lessons from Pseudogymnoascus destructans, the causative agent of white-nose disease in bats
TLDR
Results from the intensively sampled site show higher measures of genotypic richness on walls compared to bats, the absence of genic differentiation between bats and walls, and stable relative abundance of multi-locus genotypes over multiple winter seasons, which clearly implicates hibernacula walls as the main environmental reservoir of the pathogen. Expand
A Rapid, in-Situ Minimally-Invasive Technique to Assess Infections with Pseudogymnoascus destructans in Bats
Emerging infectious diseases may become serious threats to wildlife, a prominent example being the white-nose disease (WND). In case of WND, the cold-loving fungus Pseudogymnoascus destructansExpand
Screening and Biosecurity for White-nose Fungus Pseudogymnoascus destructans (Ascomycota: Pseudeurotiaceae) in Hawai‘i
Abstract:Introduced pathogens causing emerging infectious diseases (EIDs) are serious contemporary threats to animal, plant, and ecosystem health. The invasive fungus, Pseudogymnoascus destructans,Expand
Genetic diversity in a long‐lived mammal is explained by the past’s demographic shadow and current connectivity
TLDR
An integrative approach is presented that disentangles and quantifies the contribution of different connectivity measures in addition to contemporary colony size and historic bottlenecks in shaping genetic diversity in Rhinolophus hipposideros, highlighting the relevance of disentangling them to ensure appropriate conservation strategies. Expand
Interspecific competition in bats: state of knowledge and research challenges
Interspecific competition (IC) is often seen as a main driver of evolutionary patterns and community structure. Bats might compete for key resources, and cases of exaggerated divergence ofExpand
Mating type determination within a microsatellite multiplex for the fungal pathogen Pseudogymnoascus destructans, the causative agent of white-nose disease in bats
TLDR
Three mating type-specific primer sets were designed and tested on 80 isolates and will have great utility in better understanding and predicting the population dynamics and evolutionary potential of this fungus, including the emergence of virulent strains. Expand
Heterothermy and antifungal responses in bats.
TLDR
The Th17 and neutrophil responses, normally beneficial antifungal mechanisms, appear to be sources of immunopathology for susceptible bat species, because they are hyperactivated after return to homeothermy. Expand

Diseases and Causes of Death in European Bats: Dynamics in Disease Susceptibility and Infection Rates
TLDR
The clear seasonal and individual variations in disease prevalence and infection rates indicate that maternity colonies are more susceptible to infectious agents, underlining the possible important role of host physiology, immunity and roosting behavior as risk factors for infection of bats. Expand
Multiple mortality events in bats: a global review.
TLDR
Trends in the occurrence and apparent causes of multiple mortality events (MMEs) in bats around the world are reviewed and qualitatively described. Expand
Return of the bats? A prototype indicator of trends in European bat populations in underground hibernacula
TLDR
It is suggested that after a period of strong decline in the 20th century, populations of most of the investigated bat species are stabilising or recovering, although with profound differences between European bio-geographical regions and countries. Expand

Pan-European Distribution of White-Nose Syndrome Fungus (Geomyces destructans) Not Associated with Mass Mortality
TLDR
The characterisation of the temporal variation in G. destructans growth on bats provides reference data for studying the spatio-temporal dynamic of the fungus, and the presence of G. destructionans spores on cave walls suggests that hibernacula could act as passive vectors and/or reservoirs for G.destructans and therefore, might play an important role in the transmission process.

Skin Lesions in European Hibernating Bats Associated with Geomyces destructans, the Etiologic Agent of White-Nose Syndrome
White-nose syndrome (WNS) has claimed the lives of millions of hibernating insectivorous bats in North America. Its etiologic agent, the psychrophilic fungus Geomyces destructans, causes skin lesionsExpand
Altitudinal migration in bats: evidence, patterns, and drivers
TLDR
The evidence supporting the existence of altitudinal bat migrations worldwide is comprehensively reviewed, basic patterns of migration in temperate and tropical regions are described, and hypotheses potentially explaining these migrations are proposed. Expand
White-Nose Syndrome fungus introduced from Europe to North America
TLDR
The first informative molecular comparison between isolates from North America and Europe is presented and strong evidence for the long-term presence of the fungus in Europe and a recent introduction into North America is provided. Expand
White-nose syndrome: is this emerging disease a threat to European bats?
TLDR
An international WNS consortium of 67 scientists from 29 countries was assembled and the most important research and conservation priorities were identified to assess the risk of WNS to European bats. Expand
Review of historical unusual mortality events (UMEs) in the Gulf of Mexico (1990-2009): providing context for the multi-year northern Gulf of Mexico cetacean UME declared in 2010.
TLDR
Evidence is provided that the most common causes of previous UMEs are unlikely to be associated with the current UME and that the current northern GoM UME has lasted more than 48 mo and has had more than 1000 reported mortalities within the currently defined spatial and temporal boundaries of the event.
