The effect of chronic emotional stress on the behaviors of rats and its changing trend

open access: yes, 2003
目的探讨空瓶刺激诱发的慢性情绪应激对大鼠行为的影响及行为变化的趋势.方法利用空瓶刺激诱发的情绪应激模型,观察记录连续14次,每次10分钟的情绪应激期间,情绪应激组、对照组和生理应激组大鼠的攻击性行为、探究行为和修饰行为的表现.结果连续14次的情绪应激期间,与对照组和生理应激组相比,情绪应激组大鼠均表现出明显的攻击性行为,而对照组和生理应激组大鼠仅表现为探究和修饰行为.结论慢性情绪应激能诱发大鼠行为的明显改变,且这种行为的改变与应激频率无关.中国科学院知识创新工程项目 ...

A behavioral study of timing task in rats

open access: yes, 2007
目的 观察大鼠对时间的感知过程中各种行为之间的关系,探讨操作动机对大鼠时间感知的影响.方法 采用断水24h的雄性SD大鼠执行时间反应分辨任务.在听到声音信号并完成鼻触行为之后,大鼠要踩压杠杆并保持4~5 s后松开杠杆,才能得到50μl水作为奖赏.若过早或过晚松开则没有奖赏.分析声音信号和鼻触行为之间的声音反应潜伏期及鼻触行为和踩杠杆之间的踩杠杆潜伏期与操作正确性之间的关系,以及这些潜伏期与保持踩压杠杆的时间(计时期,Timing)之间的关系.结果 在计时准确的操作中,声音反应潜伏期和踩杠杆潜伏期都比较短[

Changes of Potential Suitable Areas for Lynx Under Climate Change in Mohe Area, Daxing'anling Mountains, China 气候变化下中国大兴安岭漠河地区猞猁潜在适宜区的变化

open access: yesWildlife Letters, EarlyView.
Climate change drives shifts in suitable habitats for Eurasian lynx and its prey (hare, roe deer) in Mohe, Daxing'anling Mountains. Under RCP scenarios, moderate warming (RCP4.5) promotes substantial habitat expansion, while high‐emission conditions (RCP8.5) lead to strong expansion in the 2050s but slower gains and partial contraction by the 2070s ...

Movement and Space Use Patterns of the Beale's Eyed Turtle (Sacalia bealei) Suggest Sensitivity to Environmental Changes and Poaching 比氏眼斑龟 (Sacalia bealei) 的活动与空间利用模式揭示其对环境变化及盗猎的敏感性

open access: yesWildlife Letters, EarlyView.
Using radiotelemetry, we found that the movement and home range of the endangered Sacalia bealei varied significantly across reproductive classes and seasons, with males exhibiting greater movement than females during wet and mating seasons.

Jaguar Densities and Land Cover Change in a Multi‐Use Landscape: A 10‐Year Comparison in the Colombian Llanos 美洲豹种群密度与复合用地景观下的土地覆被变化:哥伦比亚亚诺斯地区10年比较研究

open access: yesWildlife Letters, EarlyView.
We used spatially explicit capture‐recapture to estimate jaguar densities in a private reserve in the Colombian Llanos and quantified land cover change in and around the reserve from 2014 to 2024. Densities increased 22% since 2014, while disturbed land cover increased by 39%–54% around the reserve depending on buffer distance. Our study indicates that

Conflict Social Networks of Critically Endangered Alpine Musk Deer in Captivity and Relationships With Fecal Steroid Hormones 圈养极危物种马麝的冲突社交网络及其与粪便类固醇激素的关联

open access: yesWildlife Letters, EarlyView.
We conducted a grouping study on 52 adult musk deer to investigate whether group sex composition modulates aggressive behavior and stress response in captive musk deer. We found that the conflict interactions of all‐male groups were significantly more than those of mixed groups, and compared with the mixed groups, the conflict interactions of all‐male ...
