和谐边疆构建下的宗教渗透问题研究——基于对云南跨境民族的田野调查

通过对云南跨境民族地区的田野调查,该区域宗教渗透不仅没有停止,反而呈现出多样性、隐蔽性等特点。宗教渗透对跨境民族的国家政治认同等造成了严重破坏,对云南边疆社会的稳定构成了较大的威胁,成为了云南边疆地区非传统安全问题中最敏感、最复杂、最难解决的问题之一。抵御宗教渗透不仅要完善政府宗教管理能力、改善经济条件等,更要调动作为文化主体者的跨境民族自身的"文化自觉",以主动抵御宗教渗透。只有如此才是最有效的抵御宗教渗透举措,才最终有利于和谐边疆的构建。     

Long-term increases in clutch size in common snapping turtles (Chelydra serpentina) and diamondback terrapins (Malaclemys terrapin)

Clutch size (CS) is a well-studied life history characteristic, and optimal egg size theory predicts that CS should correlate positively with reproductive investment. Turtles are good subjects for studies of reproductive strategies because few turtle species exhibit parental care; therefore quantifying their short-term reproductive investment is mostly limited to measuring egg size and number. Clutch size is usually reported as an average value for each turtle population, and where CS variation is noted, it is usually attributable to variation in adult body size. In two long-term studies of ecologically dissimilar species we detected a dramatic increase in CS in a common snapping turtle (Chelydra serpentina) population and in a diamondback terrapin (Malaclemys terrapin) population. It is unknown whether these changes are due to either variation in adult body size or resource availability; but the temporal patterns we observed have apparently never been reported previously. These trends remain unexplained and should be explored further.
