Connaissez-vous la barbastelle ? C'est une chauve-souris, très présente dans la région Auvergne. Elle fait partie des nombreuses espèces menacées. Explications.
Le Conservatoire d'espaces naturels des Pays de la Loire lance la seconde phase d'une cagnotte en ligne pour financer l'achat de deux refuges pour chauves-souris. Un des deux sites concernés se trouve à Herbignac, en Loire-Atlantique.
Les petits mammifères étaient bloqués après un éboulement de talus survenu à hauteur de la commune de Légny.
Des mammifères avec des ailes ?! Ce sont les chauves-souris. Il en existe plusieurs espèces, toutes protégées, dans les Pyrénées-Orientales et dans l'Aude.
La municipalité a lancé un appel d'offres pour réhabiliter la grotte Loubière, dans le 13e arrondissement, afin qu'elle puisse de nouveau accueillir les chauves-souris.
Seba's short-tailed bat (Carollia perspicillata) lives in the subtropical and tropical forests of Central and South America, where it mostly feeds on pepper fruit. The animals spend their days in groups of 10 to 100 individuals in hollow trunks and rocky caverns, and at night they go foraging together. They communicate using sounds that create distinct ambient noise in the colony—like the babble of voices at a lively party.
Des chauves-souris avaient été repérées lors de la destruction de l'ancienne piscine de Luçon. Une cave a été créée en compensation, pour abriter ces utiles mangeurs de moustiques.
Echolocating bats emit echolocation calls from the mouth or nose. Bats that emit calls from the nose have oddly developed dome-shaped nasal bones, but variations in the morphology of these bones are poorly understood. This study compared trends in the morphological variations of the cranium focusing on smooth structure such as the nasal swellings and the braincase, and investigated the morphological variability correlated with ultrasound vocalizations. We newly constructed three-dimensional (3-D) skull mesh models of the two Japanese rhinolophid species Rhinolophus nippon and Rhinolophus cornutus from the Korean Peninsula, the Japanese Archipelago, and Jeju Island, and compared the variations in cranium size and shape using 3-D geometric morphometrics. Additionally, we also tested trends in two representative body size indices, forearm length and centroid size. The results indicate that forearm length and log-transformed centroid size represented different trends among local populations. The results of 3-D geometric morphometrics show a significant difference in cranium shape between the two species, and between the Jeju Island population and the Japanese mainland population of R. nippon, indicating variability in the pair of nasal swellings related to nasophonation of the echolocation call. The anterior median swelling varied within the R. nippon populations, and the posterior median swelling varied between R. nippon and R. cornutus. These findings suggest that the variability between the anterior median swelling creates different echolocation peak frequencies in local populations, and that the posterior median swellings are quite similar among local populations because of the strong functional constraint of diet and echolocation.
Most bats patrol the night sky in search of insects. New World leaf-nosed bats take a different approach. Among the more than 200 species of leaf-nosed bats, there are those that hunt insects; drink nectar; eat fruit; munch pollen; suck blood; and prey on frogs, birds, lizards and even other bats. T
Des pays du monde entier se réunissent à partir de lundi et jusqu'au 17 février en Ouzbékistan pour se pencher sur le sort de ces espèces, qui incluent les tortues marines et les baleines.
La Presse vous propose un tour d’horizon de l’impact de la présence des chauves-souris sur l’humain et vice-versa.
Découverte en 2016 cette espèce endémique de chauve-souris, unique en France, a été officiellement décrite dans un article scientifique publié par Sébastien Puechmaille, généticien à l’Institut des sciences de l’évolution de Montpellier.

Pour préserver des colonies de chauves-souris pendant leur période d’hibernation, Val de Berry a décalé deux chantiers d’ampleur à Bourges : une démolition et une réhabilitation. Une première dans le pays.
Les travaux de la maison des chauves-souris sur le site de l’ancienne friche industrielle de la Belle-Angèle, à Pont-Aven, avancent à grands pas. Les travaux devraient s’achever fin avril et sont réalisés par des entreprises locales
Il s'agit de se pencher à la fois sur l'état de santé de ces territoires et sur la conservation des chauves-souris vis-à-vis du réchauffement climatique pour mieux ensuite restaurer ces zones humides si importantes pour la biodiversité. C'est tout le sens d'un programme inédit, Rest-Chir'Eau, mené par les chercheurs de la Tour du Valat, à Arles. De quoi servir de modèle pour tous les marais de la planète. Et mieux résister au changement climatique.
Unintended consequences of increasing wind energy production include bat mortalities from wind turbine blade strikes. Ultrasonic deterrents (UDs) have been developed to reduce bat mortalities at wind turbines. Our goal was to experimentally assess the species-specific effectiveness of three emission treatments from the UD developed by NRG Systems. We conducted trials in a flight cage measuring approximately 60 m × 10 m × 4.4 m (length × width × height) from July 2020 to May 2021 in San Marcos, Texas, USA. A single UD was placed at either end of the flight cage, and we randomly selected one for each night of field trials. Trials focused on a red bat species group (Lasiurus borealis and Lasiurus blossevillii; n = 46) and four species: cave myotis (Myotis velifer; n = 57), Brazilian free-tailed bats (Tadarida brasiliensis; n = 73), evening bats (Nycteceius humeralis; n = 53), and tricolored bats (Perimyotis subflavus; n = 17). The trials occurred during three treatment emissions: low (emissions from subarrays at 20, 26, and 32 kHz), high (emissions from subarrays at 38, 44, and 50 kHz), and combined (all six emission frequencies). We placed one wild-captured bat into the flight cage for each trial, which consisted of an acclimation period, a control period with the UD powered off, and the three emission treatments (order randomly selected), each interspersed with a control period. We tracked bat flight using four thermal cameras placed outside the flight cage. We quantified the effectiveness of each treatment by comparing the distances each bat flew from the UD during each treatment vs. the control period using quantile regression. Additionally, we conducted an exploratory analysis of differences between sex and season and sex within season using analysis of variance. Broadly, UDs were effective at altering the bats’ flight paths as they flew farther from the UD during treatments than during controls; however, results varied by species, sex, season, and sex within season. For the red bat group, bats flew farther from the UD during all treatments than during the control period at all percentiles (p < 0.001), and treatments were comparable in effectiveness. For cave myotis, all percentile distances were farther from the UD during each of the treatments than during the control, except the 90th percentile distance during high, and low was most effective. For evening bats and Brazilian free-tailed bats, results were inconsistent, but high and low were most effective, respectively. For tricolored bats, combined and low were significant at the 10th–75th percentiles, high was significant at all percentiles, and combined was most effective. Results suggest UDs may be an effective means of reducing bat mortalities due to wind turbine blade strikes. We recommend that continued research on UDs focus on low emission treatments, which have decreased sound attenuation and demonstrated effectiveness across the bat species evaluated in this study.
