The winter community structure of bats visiting Muierilor Cave, Romania, was studied between 2004 and 2008. Field observations revealed the presence in the hibernacula of the following species: Rhinolophus ferrumequinum, Rhinolophus hipposideros, Myotis myotis/oxygnathus, Myotis emarginatus, Myotis daubentonii and Miniopterus schreibersii. The hibernating bat assemblages were characterized by a significant dominance of R. ferrumequinum and M. schreibersii. During the eight visits conducted at Muierilor Cave in the winter months the maximum number of bats recorded was 2830. Our observations indicate that in spite of frequent disturbance arising from speleotourism, Muierilor Cave is one of the biggest and most important bat hibernacula in Southern Carpathians.

    Background: White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America in 2006, where over a million bats died since then. In Europe, G. destructans was first identified in France in 2009. Its...

    Habitat loss is the leading cause of decline in wildlife diversity and abundance throughout the world, but its effects on wildlife are not always predictable. Matrix population modeling is an increasingly common tool used to predict the effects of habitat loss. In spite of the growing number of...

    Context: Unveiling the scale at which organisms respond to habitat features is crucial to understand how they are influenced by anthropogenic environmental changes. We implemented species distribution models (SDMs) based on multiple-scale landscape pattern analysis for four bat species...

    Understanding the specific habitat requirements of reptiles during different life stages or seasons is critical to conserving viable populations. Northern Pinesnakes (Pituophis melanoleucus) are one of the few species that spend the winter in underground hibernacula, which they excavate...

    The ability to predict the effects that new or modified roads will have on species or populations of conservation interest is critically important to protection efforts. We documented patterns of movement and spatial dispersion of two sympatric snake populations by radiotracking 34 Eastern...

    In order to monitor bat population trends, an annual census is performed of all known underground hibernacula in Europe. During these censuses, bats are sometimes found to show signs of arousal, presumably from non-tactile stimuli caused by the observer, e.g. air currents, sound, light or an...

    Snakes are often highly selective in the choice of sites for hibernation, and suitable sites can potentially be a limiting resource. Hibernating Louisiana Pine Snakes (Pituophis ruthveni; N = 7) in eastern Texas and Black Pine Snakes (Pituophis melanoleucus lodingi; N = 5) in Mississippi were...

    During close bodily contact, many species transfer substances that influence the behaviour or physiology of conspecifics. Such transfer is especially common during courtship and copulation. When this is the case the involved bioactive substances are favoured by sexual selection because their...
