Entering the new millennium, the ocean science community begins to establish a seafloor observatory network to explore and understand the temporal variability of ocean system including its physical, chemical, biological and geological processes. This will be the third platform of Earth system observation after the first one from the land and ocean surface, and the second from the space. The real-time continuous observations from the sea floor will establish a long-term presence in the ocean and, hence, fund...

Exactly 30 years ago, the first discovery on seafloor hydrothermal activity and its associated living community was made at Galapagos Rift area. Soon after, this event rocked the fields of geosciences, and shortly after the biosciences. Since then, this discovery has been directing our effort in linking the mantle activity to chemical and biological developments in our ocean, and guiding our passion for understanding the rising of the life in the ocean at the early stage of our planet. Even now, after this ...

This paper reviews the history of the scientific ocean drilling programs over the past 40 years and reports selected important scientific achievements obtained by the programs. Using the new multiple-platform approach to scientific ocean drilling and a new process-oriented approach to research, the Integrated Ocean Drilling Program (IODP) will focus on three broad scientific themes: The deep biosphere and the subseafloor ocean; Environmental change, processes and effects; Solid earth cycles and geodynamics....

In this article, some concepts about biological invasion were presented and the process of alien species change to invasive species was summarized and primary types of biological invasion were concluded. Furthermore, the mechanism of invasion was elaborated, some hypotheses that relate to alien species and the ecological environment of the invaded habits were analyzed, and the damage of invasive species to the human was described. With the study on urban vegetation of Shanghai, the present situation of alie...

In recent decades, the grassland ecological environments of the Qinghai-Tibetan Plateau were degraded continuously, which have been paid high attention by human beings. The actuality, the causes and the improvement techniques of grassland degradation in alpine meadow of the Qinghai-Tibetan Plateau China and the ecological restoration measures and aims were discussed in this paper. The authors put forward some measurements and advices for the protection and construction of the meadow ecosystem and its sustai...

The one mandible of Sihongtherium Liu et Zhang was found recently in the Yuhuashi Bed of Liuhe Region, Nanjing. Sihongtherium Liu et Zhang belongs to Anthracotheriidae Gill of Suiformes Jaeckel, Artiodactyla Owen. It may be referred to the middle Miocene in age. It is also a very rare and important fossil. The age of the Yuhuashi Bed has been a topic of long debate, either Pliocene or Miocene. The discovery of Sihongtherium Liu et Zhang from in Yuhuashi Bed not only provide a new evidence for the age of the...

In this article, new opinion on the evolutionary mechanism of multicelluarity was presented, i.e., the evolution of life was a process of efficiency optimization for survival. Therefore an inevitable conflict that between individual and overall interests within multicellularity was occured. This should be coordinated to assure the overall efficiency which hints that regulation were of ultimate importance. A suggestion that the emergence of regulation mechanism was evolved in an intelligence-based way. Hypot...
