.Wildlife Conservation Society Launches Digitized Department of Tropical Research Film Collection. The WCS Library and Archives, based at the Bronx Zoo, released its newly digitized?Department of Tropical Research (DTR) Film Collection. The project has brought 64 historical film reels to the public, capturing a unique record of WCS’s DTR expeditions from the 1920s through the 1960s. These expeditions spanned terrestrial and marine tropical regions across the globe, and the DTR was among the first Western scientists to study the interconnectedness of tropical wildlife and their habitats through close, first-hand observations.
