为了明晰食物丰容对猕猴(Macaca mulatta)行为的影响,采用瞬时扫描法对南京红山森林动物园86只猕猴进行食物丰容前、后日行为时间节律的研究。结果表明:(1)丰容前猕猴在白天通常以休息(日均43.80%)、摄食(日均34.60%)和攀爬移动行为(日均16.40%)为主;(2)丰容后,摄食行为09:00和15:00极显著低于丰容前 ...

丰容能提高圈养动物福利和行为多样性。2018年10—12月,对深圳野生动物园半散放环尾狐猴(Lemur catta)进行食物丰容与环境丰容,采用焦点取样法和瞬时扫描取样法观察丰容前、食物丰容和环境丰容阶段的环尾狐猴行为,比较分析不同丰容阶段环尾狐猴的日行为时间分配和行为节律变化。结果表明:食物丰容后环尾狐猴的搜寻行为显著增加,环境丰容后玩耍行为显著增多,这两个丰容阶段环尾狐猴的攀爬、行走、社群行为均显著增加,而睡觉、休息和异常行为则显著下降。丰容后环尾狐猴的活动节律也发生了变化 ...

2015年1—5月,对上海动物园西天鹅湖中的岛屿进行丰容改造,采用定点观察和瞬时扫描相结合的方法,比较丰容前、丰容后天鹅湖中天鹅类和雁类的空间分布特征和丰容有效性。结果表明:开展岛屿丰容后,天鹅类的活动范围均有所减少,由(5671.7±967.1)m2减少为(3756±1003.7)m2,但无显著差异(one-way ANOVA,F=5.667,P=0.076);雁类的活动范围亦减小,由(4034±882.4)m2减少为(3874.7±1454.1)m2,无显著差异(one-way ANOVA,F=0 ...

Habitat and spatial trends of U.K. wintering waterbird populations over 50 years
Abstract The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups ...

ABSTRACT Aqueous zinc‐ion hybrid capacitors (ZICs) bridge the gap between high‐energy batteries and high‐power supercapacitors, yet their performance is fundamentally bottlenecked by the micropore confinement effect in carbon cathodes, which restricts hydrated Zn2+ transport and active site utilization.

ABSTRACT Nickel oxide (NiO)‐based electrodes with high theoretical specific capacitance can effectively increase the energy density of supercapacitors—the key factor limiting their practical deployment. However, several issues still restrict the production of advanced NiO‐based electrodes.

ABSTRACT Rechargeable aluminium‐ion batteries (RAIBs) are promising candidates for sustainable energy storage owing to their low cost, safety, and resource abundance. However, the lack of durable cathode materials restricts their development. Here, we propose a topology‐guided design strategy by synthesizing three thioether‐bridged naphthoquinone ...

ABSTRACT Efficient catalytic materials are vital for addressing the polysulfide shuttle and sluggish redox kinetics in lithium–sulfur batteries. Herein, we report a facile sugar‐blowing method to prepare porous carbon‐supported FeCoNiCuPt high‐entropy alloy (HEA) nanospheres with abundant lattice defects in a single crystalline phase.
