We examine three distinctive biostratigraphic signatures of humans associated with hunting and gathering, landscape domestication and globalization. All three signatures have significant fossil records of regional importance that can be correlated inter‐regionally and help describe the developing pattern of human expansion and appropriation of resources. While none have individual first or last appearances...
Biobased productsare non‐food goods derived from agricultural and forestry materials. Products made from biomaterials could substitute for petroleum‐based inputs used to make everyday household goods. This studyestimates consumer willingness to pay (WTP) for the attributes of single‐use eating‐ware (SUEW) plates made from biobased materials. Attributes considered are product material, degradability,...
Approximately 13 km south of Gulf Shores, Alabama (United States), divers found in situ baldcypress (Taxodium distichum) stumps 18 m below the ocean surface. These trees could have only lived when sea level fell during the Pleistocene subaerially exposing the tectonically stable continental shelf. Here we investigate the geophysical properties along with microfossil and stratigraphical analyses of...
