Long-eared Myotis Found in Saskatchewan

Keen's Long-eared Bat, Myotis keenii, Confirmed in Southeast Alaska

Myotis keenii is apparently restricted to the Pacific coastal forests of northwestern North America. The only documentation of M. keenii in Alaska has been a specimen collected in 1887, causing uncertainty about whether this species normally occurs there. We describe two new records which indicate that M. keenii may be a regular member of the Southeast Alaska fauna and we provide measurements a...

Current status of the Northern Long-eared Myotis (<i>Myotis septentrionalis</i>) in northwestern Nebraska

The Northern Long-eared Myotis (Myotis septentrionalis; Order: Chiroptera) occurs in eastern, southern, and northern Nebraska, but its current distribution in northwestern parts of the state is unclear due to its recent arrival to the region. We investigated the status of this species in the Pine Ridge via mist net (2011-2014) and acoustic surveys (2014). We documented nine species of bats in t...

Internal Cavity Characteristics of Northern Long-eared Bat (Myotis septentrionalis) Maternity Day-roosts

Echolocation and passive listening by foraging mouse-eared bats Myotis myotis and M. blythii.

The two sibling mouse-eared bats, Myotis myotis and M. blythii, cope with similar orientation tasks, but separate their trophic niche by hunting in species-specific foraging microhabitats. Previous work has shown that both species rely largely on passive listening to detect and glean prey from substrates, and studies on other bat species have suggested that echolocation is ;switched off' during...

Plasma proteomic analysis of active and torpid greater mouse-eared bats (Myotis myotis)

Hibernation is a physiological adaptation to overcome extreme environmental conditions. It is characterized by prolonged periods of torpor interrupted by temporary arousals during winter. During torpor, body functions are suppressed and restored rapidly to almost pre-hibernation levels during arousal. Although molecular studies have been performed on hibernating rodents and bears, it is unclear...
