Long-term trend monitoring efforts for bats on National Wildlife Refuges have been prompted by a paucity of significant population information and precipitous declines in many bat species across the eastern United States. Acoustical detection of search-phase echolocations of bats provides an efficient means to identify bats to species without capture. We provide preliminary summary data for bat species richness and relative abundance using acoustical detection from road-based transects at 56 National Wildlife Refuges and 2 Ecological Field Offices across USFWS Regions 2, 3, and 4 from 2012-2015. We detected 13 species of bats, with species richness varying considerably (1-12) and more northern locales demonstrating...

The American sand lance (Ammodytes americanus, Ammodytidae) and the Northern sand lance (A. dubius, Ammodytidae) are small forage fishes that play an important functional role in the Northwest Atlantic Ocean (NWA). The NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing and energy development. We need a better understanding of the biology, population dynamics and ecosystem role of Ammodytes to inform relevant management, climate adaptation and conservation efforts. To meet this need, we synthesized available data on the (a) life history, behaviour and distribution; (b) trophic ecology; (c) threats and vulnerabilities; and (d) ecosystem services role of Ammodytes in the...
