In November 2009, an autonomous underwater glider (AUG) was deployed for a period of 12 days on the Wisconsin Shelf of Lake Superior. During this period, the AUG made repeated cross-shelf transects from 3 km to 13 km offshore, making 26 cross-shelf transects in all, during which time temperature was measured. Each of these transects displayed a mid-shelf temperature maximum roughly 8 km offshor...

Direct velocity measurements of the Malvinas Current (MC) were carried out on multiple occupations five transects across flow using a Shipborne Acoustic Profiler (SADCP) R/V Akademik Sergey Vavilov and Mstislav Keldysh. These data are used to determine local features three-dimensional field current. The covered northern branch Antarctic Circumpolar (ACC) southern part MC. Five located at 350–55...

The population of the Western Arctic Herd, estimated at 490 000 caribou (Rangifer tarandus granti) in 2003, is at its highest level in 30 years. Twenty permanent range transects were established in the winter range of the Western Arctic Herd in 1981 to assess the impacts of grazing. These transects were revisited in 1995 and 1996 (1995/96). Only 18 of the transects were re-located, so an additi...

Deforestation causes habitat loss, fragmentation, degradation, and can ultimately cause extinction of the remnant species. Tropical montane birds face these threats with the added natural vulnerability of narrower elevational ranges and higher specialization than lowland species. Recent studies assess the impact of present and future global climate change on species' ranges, but only a few of t...

Due to increasing threats facing bats, long-term monitoring protocols are needed to inform conservation strategies. Effective monitoring should be easily repeatable while capturing spatio-temporal variation. Mobile acoustic driving transect surveys ('mobile transects') have been touted as a robust, cost-effective method to monitor bats; however, it is not clear how well mobile transects represe...

Demersal trawling causes significant impact on marine benthic habitats including sediment biogeochemistry and faunal composition. To examine the effect of shrimp trawling on benthic sedimentary habitats a replicated Before/After (B/A) experiment was performed in the Gullmarfjord, Western Sweden, after 6 years protection against trawling activities. The experimental area was randomly divided int...

A community of small mammals was studied in seasonal semideciduous submontane forest in the state of Mato Grosso, Brazil. This study evaluated the use of edge and matrix pasture, by different small mammal species. Overall, 31 areas were studied, with a total sampling effort of 33,800 trap x nights. Only seven of the 25 species captured in the study sites were able to use the pasture matrix; we ...
