Abstract: Specific stress polypeptides were detected in three drought-resistant cyanobacteria ( Phormidium autumnale , LPP4 and Chroococcidiopsis sp.) subjected to matric- and osmotic-water stress. Drought stress caused the induction of at least 2–3 new polypeptides of apparent molecular masses of 30 kDa and 40–45 kDa. The polypeptide of 30 kDa was located in the thylakoid membranes, and the 45-kDa polypeptide in the cytoplasm. When these cyanobacteria were exposed to salt stress polypeptides of similar size appeared. 相似文献

The proximal portion of a subfossil monkey femur found in a Jamaican cave shares all the femoral characters of a mature male Cebus apella.The fragment alone, however, does not prove conspecificity. The Jamaican femur is also of a size that could belong to the
extinct Xenothrix mcgregoriof the same island. In contrast, the distal portion of a monkey tibia recovered from a kitchen midden in the Dominican Republic
cannot be identified with that of any known living platyrrhine or catarrhine monkey. Geological age, geographic locality,
and size of fragment point to probable alignment of the tibia with the recently extinct cebid Saimiri bernensis.Although no conclusive identifications are made, the distinctive characters of the two limb bones are described on the basis
of comparisons with femurs and tibias representing all genera of living platyrrhines, most genera of catarrhine monkeys, and
some strepsirhines. 相似文献

Our knowledge of prehistoric fishermen in the Eastern Mediterranean area is very scanty since most of the ancient coastal
settlements are today inundated by the sea. The present paper describes and analyzes the human remains revealed and excavated
in the 8,000 year-old submerged site at Atlit-Yam, Israel. The skeletal material indicates extensivce marine activities among
the inhabitants of the village, including deep sea fishing, diving and fishnet production. The morphological similarity to
the nearby Natufian population (Nahal Oren) points to population continuity in the region. The possibility of seafaring and
relationships to pupulations of major mediterranean islands is also discussed. 相似文献
