野生动物学报野生动物的活动节律和家域特征是其为适应内外环境变化而形成的生存模式，研究活动节律和家域特征有助于深入了解野生动物生态适应性，维护生态平衡，并有助于制定科学保护策略。因此，基于北斗卫星追踪项圈监测技术，深入研究了贺兰山岩羊（Pseudois nayaur）全年的活动节律和家域特征，以及不同季节、性别的个体差异。研究表明：（1）岩羊属于晨昏性动物（06：00—10：00、16：00—20：00），4个季节均表现为双峰模式的日活动节律；（2）岩羊全年的活动速率为（0.17±0.51） km/h ...

栗子坪自然保护区林分类型对土壤化学计量特征、微生物及其季节动态响应
Shuitu Baochi Xuebao[目的] 为揭示栗子坪自然保护区林分类型对土壤有机碳、氮、磷含量的垂直分布特征、土壤化学计量特征(C/N、C/P、N/P)、酶活性、微生物及其季节响应。[方法] 选取旱季、雨季的青冈-川杨阔叶混交林、栓皮栎落叶阔叶林、冷杉-云杉针叶混交林和石棉玉山竹竹林土壤为研究对象,阐明林分类型对土壤化学计量特征、酶活性、微生物及其季节动态响应特征。[结果] (1)4个林分类型土壤理化性质和酶活性均表现为雨季大于旱季;(2) C/N在青冈-川杨阔叶混交林、冷杉-云杉针叶混交林表现为旱季大于雨季,其余2个林分反之;N ...
