Thousands of vertebrate fossils have been recovered from the Gray Fossil Site, Tennessee, dating to the Miocene-Pliocene boundary. Among these are but eight specimens of bats representing two different taxa referable to the family Vespertilionidae. Comparison of the fossils with Neogene and Quaternary bats reveals that seven of the eight specimens pertain to a species of Eptesicus that cannot b...

As a postural behavior, gliding and soaring flight in birds requires less energy than flapping flight. Slow tonic and slow twitch muscle fibers are specialized for sustained contraction with high fatigue resistance and are typically found in muscles associated with posture. Albatrosses are the elite of avian gliders; as such, we wanted to learn how their musculoskeletal system enables them to m...

—Because they share several morphological and ecological characters, the North American sparrow (Emberizidae) genera Ammodramus, Passerculus, and Xenospiza have historically been considered members of a well-defi ned “grassland” sparrow assemblage. Relationships among the 11 members of this group have been the subject of much taxonomic debate, yet no comprehensive molecular assessment of relati...

Palaearctic species of the weevil genus Mecinus Germar, 1821 are revised. A total of 47 species are recognized, one of which, M. baridioides sp. n. is new to science. Mecinus dorsalis var. tavaresi Hoffmann, 1958 (stat. rev.) is considered as a distinct species, whereas M. alboscutellatus var. atratulus (Solari, 1933) is maintained as a subspecies of M. alboscutellatus (Hustache, 1913). The fol...

Twenty species of bats (Molossidae, Vespertilionidae) were collected from California, New Mexico, Oregon, South Carolina, Utah, and Baja California Norte (Mexico), and 29 of 404 (7%) animals, including Antrozous pallidus, Eptesicus fuscus, Myotis auriculus, Myotis californicus, Myotis ciliolabrum, Myotis evotis, Myotis lucifugus, Myotis thysanodes, Myotis vivesi, Myotis volans, Myotis yumanensi...

A proximalis humerust hosszú szakaszon érintő, darabos, a diaphysisre terjedő felkarcsont törések ellátása jelenleg is nagy kihívást jelent az ellátó sebészek számára. Célunk szárú reverz vállízületi protézissel és kiegészítő cerclage drótos rögzítéssel ellátott betegeink esetében elért funkcionális radiológiai eredmények bemutatása. 2019.07.01 2021.11.30 között 5, komplex, középső harmadot éri...

Four lines of evidence indicate that evening bats, Nycticeius humeralis, at nursery colonies in northern Missouri transfer information by following each other to feeding and roosting sites . (1) Daily estimates of insect density from five automated suction traps showed that common prey in evening bat faecal samples, small beetles and flies, occur in rich patches that persist for several days . ...
