| ectoparasite associations of bats from central pennsylvania. | between april and october 1997, 689 bats representing seven species were captured at pennsylvania's canoe creek state park. each bat was sampled for ectoparasitic arthropods, and four species were collected from 13.2% of the host individuals. ectoparasites include the bat flea myodopsylla insignis (rothschild), the wing mite spinturnix americanus (banks), the bed bug cimex adjunctus barber, and the soft tick ornithodoros kelleyi cooley & kohls. prevalence, relative density, and mean intensity we ... | 2003 | 14765658 |
| west nile virus antibodies in bats from new jersey and new york. | eighty-three serum samples were obtained from big brown (eptesicus fuscus), little brown (myotis lucifugus), and northern long-eared (myotis septentriotalis) bats (chiroptera: vespertilionidae), from new jersey and new york (usa) between july and october 2002. samples were analyzed for neutralizing antibodies to west nile virus (wnv) and st. louis encephalitis (sle) virus. one little brown bat and one northern long-eared bat tested positive for wnv neutralizing antibodies. no bats had antibodies ... | 2004 | 15362837 |
| use of artificial roost structures by bats at the indianapolis international airport. | from 1992-1996, 3204 artificial roosts of 9 types were placed in woodlots near indianapolis international airport in an effort to provide habitat for the federally-endangered indiana myotis (myotis sodalis) and to determine the feasibility of using these structures to manage bats in a rapidly developing suburban area. we surveyed these structures at least annually during 1992-1999 and found only northern myotis (myotis septentrionalis) regularly using the structures. four other species were occa ... | 2006 | 16622759 |
| temperatures and locations used by hibernating bats, including myotis sodalis (indiana bat), in a limestone mine: implications for conservation and management. | understanding temperatures used by hibernating bats will aid conservation and management efforts for many species. a limestone mine with 71 km of passages, used as a hibernaculum by approximately 30,000 bats, was visited four times during a 6-year period. the mine had been surveyed and mapped; therefore, bats could be precisely located and temperatures (t (s)) of the entire hibernaculum ceiling accurately mapped. it was predicted that bats should hibernate between 5 and 10 degrees c to (1) use t ... | 2007 | 17874161 |
| experimental assessment of the impacts of northern long-eared bats on ovipositing culex (diptera: culicidae) mosquitoes. | the importance of predation as a mortality factor in adult mosquitoes has received only limited attention in the scientific literature. despite the lack of consensus among researchers as to whether bats are important predators of mosquitoes, there have been no attempts to directly document the effect of bats on mosquito populations or behavior. we conducted an enclosure experiment to test the hypothesis that bats reduce the local abundance of ovipositing female mosquitoes by examining whether th ... | 0 | 19769034 |
| the effects of cutaneous fatty acids on the growth of pseudogymnoascus destructans, the etiological agent of white-nose syndrome (wns). | white nose syndrome (wns) greatly increases the over-winter mortality of little brown (myotis lucifugus), indiana (myotis sodalis), northern (myotis septentrionalis), and tricolored (perimyotis subflavus) bats. it is caused by a cutaneous infection with the fungus pseudogymnoascus destructans (pd). big brown bats (eptesicus fuscus) are much more resistant to cutaneous infection with pd, however. we thus conducted analyses of wing epidermis from hibernating e. fuscus and m. lucifugus to determine ... | 2016 | 27070905 |
| effects of white-nose syndrome on regional population patterns of 3 hibernating bat species. | hibernating bats have undergone severe recent declines across the eastern united states, but the cause of these regional-scale declines has not been systematically evaluated. we assessed the influence of white-nose syndrome (an emerging bat disease caused by the fungus pseudogymnoascus destructans, formerly geomyces destructans) on large-scale, long-term population patterns in the little brown myotis (myotis lucifugus), the northern myotis (myotis septentrionalis), and the tricolored bat (perimy ... | 2016 | 26872411 |
| the resistance of a north american bat species (eptesicus fuscus) to white-nose syndrome (wns). | white-nose syndrome (wns) is the primary cause of over-winter mortality for little brown (myotis lucifugus), northern (myotis septentrionalis), and tricolored (perimyotis subflavus) bats, and is due to cutaneous infection with the fungus pseudogymnoascus (geomyces) destructans (pd). cutaneous infection with p. destructans disrupts torpor patterns, which is thought to lead to a premature depletion of body fat reserve. field studies were conducted at 3 wns-affected hibernation sites to determine i ... | 2014 | 25437448 |
| white-nose syndrome and wing damage index scores among summer bats in the northeastern united states. | white-nose syndrome (wns) adversely affects millions of bats hibernating in caves of the eastern united states. beginning in 2009, the us fish and wildlife service supported use of a wing damage index (wdi) scoring system (scale of 0 to 3, or no damage to severe) to assess wing damage of bats captured during summer. based on bat captures at 459 mist net sites in pennsylvania, new york, maryland, virginia, and new jersey, usa, we questioned whether wdi scores varied by species group, date, and di ... | 2011 | 21269995 |
| a new species of eimeria (apicomplexa: eimeriidae) from the northern myotis, myotis septentrionalis (chiroptera: vespertilionidae), in oklahoma. | during september 2004, 4 adult northern myotis, myotis septentrionalis, were collected from leflore county, oklahoma (n = 2), and logan (n = 1) and yell (n = 1) counties, arkansas, and their feces examined for coccidian parasites. three of 4 bats (75%) were passing oocysts of eimeria spp. oocysts of eimeria tumlisoni n. sp. were subspherical, 17.6 × 16.8 (16-19 × 14-18) µm with a shape index of 1.0 (1.0-1.1). a micropyle and oocyst residuum were absent, although 1-2 bilobed polar granules ... | 2012 | 22509940 |
| winter activity of coastal plain populations of bat species affected by white-nose syndrome and wind energy facilities. | across the entire distribution of a species, populations may have variable responses to environmental perturbations. many bat species experience mortality in large portions of their range during hibernation and along migratory paths to and from wintering grounds, from white-nose syndrome (wns) and wind energy development, respectively. in some areas, warm temperatures may allow bats to remain active through winter, thus decreasing their susceptibility to wns and/or mortality associated with migr ... | 2016 | 27851832 |
| association, roost use and simulated disruption of myotis septentrionalis maternity colonies. | how wildlife social and resource networks are distributed on the landscape and how animals respond to resource loss are important aspects of behavioral ecology. for bats, understanding these responses may improve conservation efforts and provide insights into adaptations to environmental conditions. we tracked maternity colonies of northern bats (myotis septentrionalis) at fort knox, kentucky, usa to evaluate their social and resource networks and space use. roost and social network structure di ... | 2014 | 24468215 |
| population genetic structure within and among seasonal site types in the little brown bat (myotis lucifugus) and the northern long-eared bat (m. septentrionalis). | during late summer and early autumn, temperate bats migrate from their summering sites to swarming sites, where mating likely occurs. however, the extent to which individuals of a single summering site migrate to the same swarming site, and vice versa, is not known. we examined the migratory connectivity between summering and swarming sites in two temperate, north american, bat species, the little brown bat (myotis lucifugus) and the northern long-eared bat (myotis septentrionalis). using mitoch ... | 2015 | 25942425 |
| the gleaning attacks of the northern long-eared bat, myotis septentrionalis, are relatively inaudible to moths. | this study empirically tests the prediction that the echolocation calls of gleaning insectivorous bats (short duration, high frequency, low intensity) are acoustically mismatched to the ears of noctuid moths and are less detectable than those of aerially hawking bats. we recorded auditory receptor cell action potentials elicited in underwing moths (catocala spp.) by echolocation calls emitted during gleaning attacks by myotis septentrionalis (the northern long-eared bat) and during flights by th ... | 1993 | 8315370 |
| effects of hierarchical roost removal on northern long-eared bat (myotis septentrionalis) maternity colonies. | forest roosting bats use a variety of ephemeral roosts such as snags and declining live trees. although conservation of summer maternity habitat is considered critical for forest-roosting bats, bat response to roost loss still is poorly understood. to address this, we monitored 3 northern long-eared bat (myotis septentrionalis) maternity colonies on fort knox military reservation, kentucky, usa, before and after targeted roost removal during the dormant season when bats were hibernating in caves ... | 2015 | 25611060 |
| the neuroethology of song cessation in response to gleaning bat calls in two species of katydids, neoconocephalus ensiger and amblycorypha oblongifolia. | we investigated whether the use of primary or secondary behavioural defences is related to prey sensory thresholds using two species of north american katydids, neoconocephalus ensiger and amblycorypha oblongifolia. male katydids produce intense calling songs to attract mates, and many gleaning bat species are known to use these calls to locate them as prey. low duty cycle calling (i.e. sporadic calls) is a primary defence against gleaning bats (prevents attacks), and song cessation is a seconda ... | 2008 | 18626077 |
| the adaptive function of tiger moth clicks against echolocating bats: an experimental and synthetic approach. | we studied the efficiency and effects of the multiple sensory cues of tiger moths on echolocating bats. we used the northern long-eared bat, myotis septentrionalis, a purported moth specialist that takes surface-bound prey (gleaning) and airborne prey (aerial hawking), and the dogbane tiger moth, cycnia tenera, an eared species unpalatable to bats that possesses conspicuous colouration and sound-producing organs (tymbals). this is the first study to investigate the interaction of tiger moths and ... | 2005 | 16326950 |
| antifungal norditerpene oidiolactones from the fungus oidiodendron truncatum, a potential biocontrol agent for white-nose syndrome in bats. | white-nose syndrome (wns) is a devastating disease of hibernating bats caused by the fungus pseudogymnoascus destructans. we obtained 383 fungal and bacterial isolates from the soudan iron mine, an important bat hibernaculum in minnesota, then screened this library for antifungal activity to develop biological control treatments for wns. an extract from the fungus oidiodendron truncatum was subjected to bioassay-guided fractionation, which led to the isolation of 14 norditerpene and three anthra ... | 2020 | 31986046 |
