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 ...

Regulating Reality: Exploring Synthetic Media Through Multistakeholder AI Governance
ABSTRACT Artificial intelligence's integration into daily life has brought with it a reckoning on the role such technology plays in society and the varied stakeholders who should shape its governance. This is particularly relevant for AI‐generated, or synthetic, media, an emergent visual technology impacting perceptions of media as records of reality ...

Alloy‐Type Anode Materials for Sodium‐Ion Batteries: From Single Metals to MultiComponent Alloys
ABSTRACT Sodium‐ion batteries (SIBs) are widely regarded as a promising alternative to lithium‐ion batteries due to their abundant sodium resources, broad geographical distribution, and low cost, rendering them particularly attractive for large‐scale energy storage applications.

ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

ABSTRACT Lithium–sulfur (Li–S) batteries are promising for next‐generation high‐energy‐storage systems but are hindered by polysulfide shuttle, sluggish kinetics, and volume expansion. Conventional carbon hosts struggle to simultaneously anchor and convert polysulfides efficiently.

We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.
