Table 1 The total number of active acoustic survey samples with presence of each species (Sites), total bat echolocation calls (Total), and mean and standard error (SE) of bat echolocation calls per active acoustic sample. Samples were collected 2003–2004 and 2017 in the National Park Service National Capital Region. Mean change is the 2017 mean minus the 2003–2004 mean. P-values were from Pearson’s paired t-test. Calls were identified to species by using Kaleidoscope 4.5.0 Bats of North America 4.2.0 classifier (Wildlife Acoustics Inc., Concord, MA, USA) for the following species: Eptesicus fuscus (Big Brown bat; EPFU), Lasiurus borealis (Eastern Red bat; LABO), Lasiurus cinereus (Hoary bat; LACI), Lasionycteris noctivagans (Silver-haired bat; LANO), Myotis leibii (Eastern Small-footed bat; MYLE), Myotis lucifugus (Little Brown bat; MYLU), Myotis septentrionalis (Northern-Long eared bat; MYSE), Myotis sodalis (Indiana bat; MYSO), Nycticeius humeralis (Evening bat; NYHU) and Perimyotis subflavus (Tri-colored bat; PESU)

From: White-nose syndrome-related changes to Mid-Atlantic bat communities across an urban-to-rural gradient
