The lack of obvious morphological differences between species impedes the identification in many groups organisms. Meanwhile, DNA-based approaches are increasingly used to survey biological diversity. In this study we show that sequencing mitochondrial protein-coding gene NADH dehydrogenase, subunit 1 (nd1) from 534 bats Western Palaearctic region corroborates promise DNA barcodes two major respects. First, described with classical taxonomic tools can be genetically identified only a few...
We describe a new species of long-eared bat, genus Plecotus, from the island Sardinia (Italy). The is clearly distinguishable other European Plecotus by its mitochondrial 16S rRNA gene (4.1–9.6% sequence divergence) as well unique combination morphological characters such brownish colour dorsal pelage, relatively large thumb and claw, an almost cylindrical form penis characteristic shape baculum. most important diagnostic character long (≥ 18 mm) wide 6 tragus. currently known three...
Sardinia is home to three bat species of chief conservation importance, the endemic Plecotus sardus as well Myotis punicus and Rhinolophus mehelyi , for which Italian stronghold. We carried out two gap analyses overlapping network protected areas present on island respectively with 1) occurrence records all 2) binarized maps obtained from maximum entropy models. Unlike other species, P. known are confined central sector its suitable habitat partly overlaps that M. but not R. . Due uniqueness...
Abstract Human-induced pressures such as climate and land-use changes in the Anthropocene disproportionately threaten island ecosystems endemic species they host. Shedding light on ecological needs of is key to conservation these fragile their unique species. Here we present a bat Sardinia, long-eared Plecotus sardus , analyse relationship between this Critically Endangered insular environment at different spatial scales inform action for its conservation. We show that besides displaying...
Biomarkers in CSF can offer improved diagnostic accuracy for Alzheimer's disease (AD). The present study investigated whether the glycoprotein and putative tumor suppressor Dickkopf homolog 3 (Dkk-3) is secreted into evaluated its applicability as a marker AD. Using our highly specific immunoenzymometric assay, Dkk-3 levels were measured plasma and/or of patients suffering from depression, mild cognitive impairment (MCI), or AD compared with healthy subjects. identity was verified by western...
Abstract Aim A common pattern in biogeography is the scale‐dependent effect of environmental variables on spatial distribution species. We tested role climatic and land cover structuring genetic variation grey long‐eared bat, Plecotus austriacus, across scales. Although landscape genetics has been widely used to describe patterns gene flow a variety taxa, volant animals have generally neglected because their perceived high dispersal potential. Location England Europe. Methods multiscale...
The roost area selection of reproductive female western barbastelles was examined throughout four study seasons (2004–2007) via radio-tracking and automated acoustic monitoring. We specifically analysed the spatial structure roosting habitat fidelity including a flight path connecting roosts. radio-tracked 13 colony members to 46 natural roosts, mainly dead oaks with large pieces loose bark. Simultaneous tracking pairs females revealed existence subgroups fission-fusion-behaviour in...
The niche variation hypothesis suggests that a population's ability to react varying environmental conditions depend on the behavioural variability of its members. However, most studies bats, including work habitat use western barbastelle bat, Barbastella barbastellus, have not considered sex-specific and individual variability. We studied 12 female five male bats within their home ranges with respect available types by applying kernel methods Euclidean distances. Our results indicate...
Unlike malignant primary central nervous system (CNS) tumours outcome data on non-malignant CNS are scarce. For patients diagnosed from 1996 to 2002 5-year relative survival of only 85.0% has been reported. We investigated this rate in a contemporary patient cohort update information survival. followed 3983 cases within the Austrian Brain Tumour Registry. All were newly 2005 2010 with histologically confirmed tumour. Vital status, cause death, and population life tables obtained by 31...
We present a revision of the genus Troglophilus in western part Balkan Peninsula based on morphological and genetic analysis, provide distribution data for species. The results these analyses reduced number known taxa within this area to five valid species: cavicola (Kollar, 1833), neglectusKrauss, 1879, ovuliformisKarny, 1907, brevicauda Chopard, 1934, lazaropolensis Karaman, 1958. A new species zorae sp. nov. is described neglectus serbicus Maran, 1958, vlasinensis bukoviki 1968 pretneri...
Alzheimer's disease (AD) is characterized by extracellular beta-amyloid plaques and intracellular tau tangles. AD-related pathology often accompanied vascular changes. The predominant lesions in AD are cerebral amyloid angiopathy (CAA) arteriosclerosis. Platelets circulate along the vessel wall responding immediately to injury. aim of present study was explore presence migration platelets (thrombocytes) sites small bleedings and/or brain. We infused fluorescently labeled red PKH26 mouse into...
Islands are biodiversity hotspots, often containing numerous endemic species. This makes them also hotspots for conservation. Within the Mediterranean region, Sardinia is known its comparatively high degree of endemism, including cryptic diversity. In this paper we aim to elucidate variability pipistrelles (Pipistrellus and Hypsugo) on Sardinia. More specifically, ask which species occur describe geographic affiliations these evolutionary lineages. We sequenced ca. 560 bp 16S rRNA gene from...
The identification of cryptic species may significantly change our view about their distribution, abundance, ecology and therefore conservation status. In the European Alps, molecular studies have revealed existence three sibling plecotine bats Plecotus auritus, austriacus and, very recently, macrobullaris. Knowledge ecological niche partitioning is a requisite to develop sound policies. Yet, this requests development unambiguous methods easily applicable in field. This study investigates...
Abstract Aim The need to forecast range shifts under future climate change has motivated an increasing interest in better understanding the role of biotic interactions driving diversity patterns. contribution shaping broad‐scale species distributions is, however, still debated, partly due difficulty detecting their effects. We aim test whether spatial exclusion between potentially competing can be detected at scale, and this pattern relates fine‐scale mechanisms coexistence. Location Western...
