Sequences of three vespertilionids by Ruedi & Mayer (2001): Vespertilio murinus Linnaeus, 1758, Myotis nattereri (Kuhl, 1817) and Myotis schaubi Kormos, 1934, were used as outgroup for rooting phylogenetic trees.
The species most-often studied using this technology are vespertilionids (Neubaum et al., 2005; Wimsatt et al., 2005; O'Shea et al., 2010; Johnson et al., 2012; Britzke et al., 2014; Ingalls, 2014), but at least one study targeted phyllostomids (Lang et al., 2005).
The species' habit of capturing prey over water is shared with only a few other Neotropical bats, including the noctilionids, the emballonurid Rhynchonycteris naso, and a few vespertilionids (Weinbeer et al., 2006; Weinbeer and Kalko, 2007), although their insect prey is typically smaller than that of other gleaners (Meyer et al., 2005).
in free-ranging vespertilionids. Histopathologic findings of the greater mouse-eared bat were consistent with those of systemic Y.
Temperate communities are much less diverse than in the tropics, often being limited to vespertilionids (as in southern Illinois), where body size ranges from the 30-g hoary bat (Lasiurus cinereus) to the 5-g small-footed myotis (Myotis leibii, Steffen et al., 2006).
This bat parasite has been previously reported from other vespertilionids including the little brown myotis (Myotis lucifugus) in New Mexico (Cain and Studier i974) and Minnesota (Macy 1931), big brown bat (Eptesicus fuscus) in Minnesota (Macy 1931), gray myotis (Myotis grisescens) in Kansas (Ubelaker 1966), western pipistrelle (Pipistrellus hesperus) in Nevada, and eastern pipistrelle (Pipistrellus [=Perimyotis] subflavus) in Nebraska (Nickel and Hansen 1967).
In particular, we predicted that the minimum body temperature in torpor is higher in free-tailed bats than in sympatric vespertilionids of similar body mass, so that the critical ambient temperature ([T.sub.ct]) below which bats in torpor increase their rate of metabolism for thermoregulation is higher in free-tailed bats than in temperate zone vespertilionids.
The city of Rosario is within the distribution range of seven species of bats, four vespertilionids: Eptesicus diminutus, Eptesicus furinalis, Lasiurus cinereus, and Lasiurus ega, and three molossids: Tadarida brasiliensis, Eumops bonariensis, and Eumops patagonicus (Barquez et al.
Records were documented for nine vespertilionids of six genera (Myotis, Lasionycteris, Pipistrellus, Eptesicus, Lasiurus, Nycticeius), and one molossid (Tadarida).
