ABSTRAcr.~BUzios Island is a fishing community of about 44 families located off the coast of Sao Paulo State, Braziil. This study focuses on the food taboos of the islanders from Buzios, specifically on prohibitions in the consumption of certain species of fish and lizard. Interviews and observations on food habits were made from November 1986 to December 1987. Some fish are avoided only when p...

Sampling of six horizons quartz-glauconite sands in Kaniv dislocations Ukraine yielded more than three thousand vertebrate specimens, including elasmobranch teeth, chimaera dental plates, actinopterygian and sauropsid teeth bones. Our study represents the first illustrated detailed description from Ukrainian Albian deposits since Rogovich (1861), whose specimens were still preserved collections...

Mammalian neocortical circuits are functionally organized such that the selectivity of individual neurons systematically shifts across the cortical surface, forming a continuous map. Maps of the sensory space exist in cortex, such as retinotopic maps in the visual system or tonotopic maps in the auditory system, but other functional response properties also may be similarly organized. For examp...

Carnivorous fungi dating back to the age of the dinosaurs have been found fossilized in circa-100-million-year-old amber. The fossil fungi used hyphal rings as trapping devices and are preserved together with their prey, small nematodes. The excellent preservation in amber allowed comparison with extant groups: On the basis of the mode of ring formation and the dimorphic mode of life, the fossi...

Carbon isotope diVerences ( 13C) between bioapatite and diet, collagen and diet, and bioapatite and collagen were calculated for four species of sirenians, Dugong dugon (Müller), Trichechus manatus (Linnaeus), Trichechus inunguis (Natterer), and the extinct Hydrodamalis gigas (Zimmerman). Bone and tooth samples were taken from archived materials collected from populations during the mid eightee...
