Little is known about the movements and home range of boreal woodland caribou (Rangifer tarandus) in the James Bay lowlands, northern Ontario. Our preliminary study involves the use of GPS collars with Argos satellite system uplink to monitor movements of... see more

To determine past distribution and relative abundance of caribou (Rangifer tarandus caribou) in the Hudson Plains Ecozone (HPE) of Ontario, we reviewed past HPE-wide winter systematic aerial surveys, partial winter systematic surveys, summer photographic ... see more

A 3-year field experiment (fall 1990-spring 1993) showed that woodland caribou (Rangifer tarandus caribou) altered their dispersion when logs were hauled through their traditional wintering area. Unlike observations in control years 1 and 3, radio-collare... see more

Two summers' field surveys at 9 locations in northwestern Ontario showed that woodland caribou (Rangifer tarandus caribou) wintering areas supported jack pine and black spruce stands with low tree densities (mean 1552 trees/ ha, 39% of a fully stocked sta... see more

Research on terrestrial migratory birds is incipient in Brazil. Geolocators have recently allowed tracking small migratory passerines, and such data combined with intrinsic markers such as stable isotopes has become invaluable in revealing migratory behav... see more

Sandy coasts are specific habitats of high ecological significance for many species of shorebirds. The Gulf of Catania, in the Eastern coast of Sicily, is considered one of the most important sandy coastal areas of the region for the wintering of differen... see more
