野生动物学报, 2009 2003年11月～2004年2月,采用瞬时扫描取样法对哈尔滨动物园1对成年灰鹤的越冬行为进行观察,探讨冬季不同温度和不同天气条件下对灰鹤越冬行为的影响,并得出结论如下:笼养灰鹤越冬期行为时间分配比例依次为静栖26.92%、进食25.96%、瞭望18.74%、啄雪草13.32%、理羽6.66%、游走4.91%、呜叫2.48%、警戒1.07%和打斗0.34%;大雾时静栖、瞭望和进食行为与正常天气相似,最为突出的是游走行为明显增多,而啄雪草行为减少了近10%,从总体上看活动量比正常天气时增多 ...

野生动物学报, 2009 采用瞬时扫描法研究了白鹤越冬行为的活动节律和时间分配。结果表明:越冬期笼养白鹤行为时间分配依次为静栖33.65%,觅食20.61%,理羽12.67%,避风11.37%,瞭望9.36%,啄雪草5.30%,游走2.96%,趴卧1.86%,鸣叫1.49%,展翅0.74%。笼养白鹤在越冬期活动有一定的节律性。两性间越冬期其行为和时间分配有一定的差异。不同的温度、天气条件,对笼养白鹤越冬行为有影响。

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, Volume 250, Issue 2, Page 1231-1247, April 2026.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

野生动物学报, 2013 为了研究圈养丹顶鹤幼鸟的行为发育规律,为今后的丹顶鹤保护以及再引入工程提供有价值的资料,2011年6～9月,采用目标动物取样法和瞬时扫描取样法,在扎龙自然保护区对6只笼养丹顶鹤幼鸟进行了研究。研究了圈养丹顶鹤幼鸟生长发育过程中的行为谱及其变化和日间行为规律的变化。结果表明,随着周龄的增加,幼鸟的休息行为时间分配随着周龄的变化明显减少,游走、取食、理羽和警戒行为的时间分配随着周龄的变化有所增加,而玩耍行为的时间分配先逐渐增大然后减少并稳定。最后,圈养丹顶鹤幼鸟的各行为时间分配分别为:游走14.83 ...

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

野生动物学报, 2012 白鹤属大型涉禽,仅分布于亚洲地区,其东亚种群数量为3 750只左右;由于环境变迁,种群数量越来越少,已被列为国家Ⅰ级重点保护动物。为阐明在沼泽湿地生态系统环境中白鹤春季的活动规律以及各种行为的时间分配,于2010年4月15日～5月13日,在吉林莫莫格国家级自然保护区对白鹤春季迁徙期行为进行了初步研究。白鹤的各种行为的时间分配依次为:觅食占64.34%、静栖占4.42%、警戒占13.92%、游走占4.57%、理羽占11.51%、其他（包括打斗、飞行、呜叫等情况）占2.56%。成体与亚成体白鹤 ...
