This Thought enriches and develops scientific socialism, the guiding ideology of the International Communist Movement. With brave new intellectual horizon, it deepens the understanding of the laws governing government by communist parties, construction of socialism and development of human society, occupying an important place of historical significance in the history of development of Marxism and the International Communist Movement. Guided by Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era, socialism with Chinese characteristics has made great historical achievements, creating new splendor and helping open new vista for the International Communist Movement.展开更多

Fifty-five actively spawning females were fitted with transmitters in 2008 and 2009 and were tracked using acoustic telemetry from May 2008 through July 2010. Fil^een crabs with transmitters also had archive depth-temperature tags attached. In addition, over 2000 spawning crabs （males and females） were tagged with US Fish and Wildlife CIdSFWS） button tags over the same period. Ninety-one percent of the crabs with transmitters were detected during this study. In the spring, crabs were primarily located in the northern section of the bay near spawning beaches, whereas in the fall crabs moved towards the deeper portions of the bay, and some may have overwIntered in the bay. There was evidence that a majority （58%-71%） of the females with transmitters spawned in two sequential seasons. One archive tag was recovered resulting in a year-long continuous record of depth and tem- perature data that, when integrated with telemetry data, indicated that the crab overwintered in the bay. The live recapture rate of crabs with USFWS button tags was 11%, with all re-sighted crabs except one observed inside Pleasant Bay. Eighty-three percent of recaptures were found within 2.5kin of the tagging location, and 51% were observed at the same beach where they were tagged. This study provides further evidence that horseshoe crabs in Pleasant Bay may be philopatric to this embayment展开更多
