Zhongguo tingli yuyan kangfu kexue zazhi, 2023 目的 探究数字化和人工两种评估方式对孤独症谱系障碍（autism spectrum disorder,ASD）儿童能力评估的一致性。方法 采用被试内实验设计招募30名2～8岁ASD儿童分别进行数字化评估和人工评估。结果 （1）数字化评估与人工评估具有较高的一致性（平均＞80%），且不受儿童性别和年龄的影响；（2）ASD儿童的数字化与人工评估得分差异有统计学意义（P＜0.05），数字化评估得分低于人工评估；在控制平板使用经验后，两种评估得分差异不存在统计学意义（P＞0.05）；（3）相较于人工评估 ...

High Risk of Extinction Across the Flowering Plant Tree of Life Revisited 再探被子植物系统发育树上的高灭绝风险
Integrative Conservation, EarlyView.Two of the 200 randomized phylogenetic trees for species in the genus Magnolia used in Forest et al., showing that the branch length of a given species varies greatly among different phylogenetic trees. ABSTRACT Forest et al. (2026; Science, 392: 655−659) evaluated extinction risk for 335,497 angiosperm species worldwide, with the Evolutionarily ...

Wildlife 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 ...

Gaoya dianqi, 2022 针对高压XLPE电缆缓冲层烧蚀故障频发，缓冲层烧蚀影响因素较多，难以准确评估在运电缆缓冲层状态的情况，提出了一种缓冲层状态模糊综合评估方法。根据缓冲层烧蚀故障机理及带材特性，建立状态评估因子及评估分级标准。在此基础上，采用改进层次分析方法确定评估因子的权重。采用模糊综合评价方法，计算缓冲层状态评估等级隶属度向量。根据最大隶属度原则确定最终评估结果。通过实例计算表明，该评估方法能够对缓冲层状态进行准确评估，有效降低人的主观因素影响，为制定在运高压XLPE电缆缓冲层状态运维管控措施提供了科学依据。

Wildlife 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

Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Wildlife Letters, EarlyView.We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Wildlife Letters, EarlyView.This study investigates the breeding success of the critically endangered White‐rumped Vulture in Khaireni Community Forest, and examines local knowledge and perceptions toward its conservation. We found that 71% of active nests were successful, with breeding success significantly influenced by the proximity to carcass deposition sites.

Wildlife Letters, EarlyView.We staged dyadic interaction trials between two kangaroo rat species threatened by habitat loss to test whether one species dominates in direct interactions in the field. We found that Stephens’ kangaroo rat (Dipodomys stephensi) residents and intruders were dominant over Dulzura kangaroo rat (Dipodomys simulans). These results suggest that D. simulans
