The role of swarming sites for maintaining gene flow in the brown long-eared bat (Plecotus auritus)

2004

Bat-swarming sites where thousands of individuals meet in late summer were recently proposed as 'hot spots' for gene flow among populations. If, due to female philopatry, nursery colonies are genetically differentiated, and if males and females of different colonies meet at swarming sites, then we would expect lower differentiation of maternally inherited genetic markers among swarming sites and higher genetic diversity within. To test these predictions, we compared genetic variance from three swarming sites to 14 nursery colonies. We analysed biparentally (five nuclear and one sex-linked microsatellite loci) and maternally (mitochondrial D-loop, 550 bp) inherited molecular markers. Three m…

Echolocation signals of the plecotine bat, Plecotus macrobullaris Kuzyakin, 1965

2006

Plecotus macrobullaris was recorded in an alpine region in Switzerland. Like other species of the genus Plecotus, P. macrobullaris emitted multiharmonic, downward frequency-modulated signals consisting mostly of the 1st and the lower part of the 2nd harmonic. Signal structure depended on the distance to the background. The shortest signals (0.8 ms) were recorded close to the background. The first harmonic began at about 46 kHz and ended around 23 kHz. Signals were emitted in groups. The longest signals (up to 7.3 ms) were recorded above a meadow, far from background targets. These signals, which were more shallowly modulated, started at about 42 kHz and ended around 15 kHz. They occasionall…

First record of brown long-eared bat Plecotus auritus (Chiroptera: Vespertilionidae) for Sicily island (Italy)

2015

The knowledge of the bat fauna of Sicily (Southern Italy) is scarce, fragmentary or sometimes even confusing. A recent review mentioned 20 species for the region, but it is likely that the checklist of bats of Sicily is still far from being exhaustive. To help fill this gap, in the past few years specific studies were carried out on the distribution of bat species in Sicily, especially in the woodlands of the Nebrodi Mountains. In the municipality of Caronia (Messina province) has captured a young female brown long-eared bat Plecotus auritus (Linneaus, 1758). The capture of P. auritus in Sicily represents the first record of brown long-eared bat Plecotus auritus for Sicily island, an intere…

Contribución al conocimiento de los murciélagos (Mammalia, Chiroptera) del Parque Natural de Penyagolosa (provincia de Castellón)

2019

Se exponen los principales resultados obtenidos en los muestreos efectuados en agosto de 2004 en el Parque Natural de Penyagolosa. La comunidad de quirópteros del Parque Natural está integrada por al menos 14 especies. Diez de ellas fueron localizadas en los muestreos, siendo ocho nuevas citas tras ellos. La revisión de la bibliografía e informes técnicos más recientes permiten añadir las restantes cuatro especies. De entre las especies localizadas en los muestreos, destacan las forestales Plecotus auritus (Linnaeus, 1758) y Barbastella barbastellus (Schreber, 1774); las fisurícolas Pipistrellus pipistrellus (Schreber, 1774) y Eptesicus serotinus (Schreber, 1774) y la cavernícola Myotis esc…

A relict tropical forest bat assemblage from the early Miocene of the Ribesalbes-Alcora Basin (Castelló, Spain)

2020

ABSTRACTWe present the bat assemblage from the early Miocene (MN4, 16.9–15.95 MY) basin of Ribesalbes-Alcora, which has yielded the remains of ten chiropteran taxa. Bat assemblages are rarely recovered in the fluvio-lacustrine fossil record. A bat species described in this work,Cuvierimops penalverisp. nov., is a new form of a typically Oligocene free-tailed bat. In addition, the other molossidsHydromops helveticus,Rhizomops cf.brasiliensis,Chaerephonsp.,Tadaridasp., and the vespertilionidsMyotis cf.intermediusandMiostrellusaff.petersbuchensis, as well as undetermined fossils ascribed to the generaSubmyotodon,Plecotus, andRhinolophusare described. This is the first record of the genusRhizom…

Multiple morphological characters needed for field identification of cryptic long‐eared bat species around the Swiss Alps

2010

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 the existence of three sibling species of plecotine bats Plecotus auritus, Plecotus austriacus and, very recently, Plecotus macrobullaris. Knowledge of the ecological niche partitioning of cryptic species is a requisite to develop sound conservation policies. Yet, this requests the development of unambiguous identification methods easily applicable in the field. This study investigates the reliability of several morphological methods used for species recognition and proposes a new identif…

2007

The lack of obvious morphological differences between species impedes the identification of species in many groups of organisms. Meanwhile, DNA-based approaches are increasingly used to survey biological diversity. In this study we show that sequencing the mitochondrial protein-coding gene NADH dehydrogenase, subunit 1 (nd1) from 534 bats of the Western Palaearctic region corroborates the promise of DNA barcodes in two major respects. First, species described with classical taxonomic tools can be genetically identified with only a few exceptions. Second, substantial sequence divergence suggests an unexpected high number of undiscovered species.

New data about Chiropterofauna of the “Monte Pellegrino” Nature Reserve (Palermo, Italy)

2021

This work increase the knowledge related to bat fauna present in the “Monte Pellegrino” Nature Reserve in the Palermo municipality. The acoustic sampling took place in the summer/autumn season using the D500X Bat detector in 22 samples. The identified signals were attributed to 8 species and one genus. The Taxa with the most passes in the reserve are: Tadarita teniotis followed by Pipistrellus kuhlii, Hypsugo savii (100% of Costancy), Pipistrellus pygmaeus, Pipistrellus pipistrellus, Plecotus sp., Miniopterus schreibersii and last with a single recording Rhinolophus ferrumequinum and Rhinolophus hipposideros. The dendrogram of similarity shows 3 distinct bats cenosis. Two samples present in…

A New species of long-eared bat (Chiroptera, Vespertilionidae) from Sardinia (Italy)

2002

We describe a new species of long eared bat, genus Plecotus, from the island of Sardinia (Italy). The new species is clearly distinguishable from other European Plecotus species by its mitochondrial 16S rRNA gene (4.1–9.6 % sequence divergence) as well as by a unique combination of morphological characters such as brownish colour of dorsal pelage, a relatively large thumb and thumb claw, an almost cylindrical form of the penis and the characteristic shape of the baculum. The most important morphological diagnostic characters is a relatively long (≥18mm) and wide (≥6mm) tragus. The new species is currently known from three localities on Sardinia. In addition to the new species we discovered …

Cryptic Diversity in Mongolian Vespertilionid Bats (Vespertilionidae, Chiroptera, Mammalia). Results of the Mongolian-German Biological Expeditions S…

2012

In contrast to the Eastern Palaearctic region a high degree of cryptic diversity was discovered among temperate bats of the Western Palaearctic region in the last ten years. Climatic oscillations caused severe changes in the distribution of species throughout the Palaearctic region during the Pleistocene. Exploring multiple taxa can help to understand general evolutionary differentiation processes. In the present study genetic variation within and among 94 Mongolian vespertilionid bats of six genera (Hypsugo, Eptesicus, Vespertilio, Myotis, Plecotus, and Nyctalus) was screened by sequencing a 798 bp fragment of the mitochondrial ND1 gene and then subsequently compared with those of Western …
