An improved particle swarm algorithm based on dynamic segmentation and neighborhood reverse learning(基于动态分级和邻域反向学习的改进粒子群算法)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
针对粒子群算法容易陷入局部最优解的问题,提出了一种基于动态分级和邻域反向学习的改进粒子群算法.该算法通过构建动态分级机制,将种群中的粒子动态地划分成3个等级,对不同等级内的粒子采取不同的扰动行为,使得粒子在增强种群多样性的同时保持向全局最优方向进化;采用粒子智能更新方式,提高了粒子的搜索能力;引入动态邻域反向学习点建立全局搜索策略,促使种群快速寻优.最后,利用多种典型测试函数对该算法进行仿真实验,结果表明,与其他几种优化算法相比,本算法具有较好的收敛性和稳定性.

武陵山脉东段华南虎重引入的种群生存力分析

open access: yes野生动物学报, 2022
华南虎(Panthera tigris amoyensis)为中国特有虎亚种,近40年在野外未见踪迹,亟待实施野外放归和野生种群重建生态工程。应用种群生存力分析漩涡模型,对拟重建的华南虎野生种群动态进行分析,对影响未来种群动态的主要因子,包括初始种群、最小存活种群和环境容纳量参数等,进行了敏感性分析。模拟分析结果表明:在自然状态、无个体补充的情形下,壶瓶山—后河国家级自然保护区华南虎野外放归备选地环境容纳量为22只,未来100年内,野生华南虎种群存活概率为085,内禀增长率为01871 ...

考虑充电需求增长的充电站动态规划方法 [PDF]

open access: yes全球能源互联网, 2019
考虑到电动汽车保有量和充电需求不断增长的现状,在满足用户需求的基础上,提出电动汽车充电站的动态规划方案,使得充电站容量和数量可随充电需求的改变而不断扩展,同时实现充电站建设投资成本最小化。该方法以充电站综合建设投资成本最小为目标,采用自适应粒子群优化算法求解充电站静态规划模型,再根据需求量的改变采用多种方法对充电站进行动态规划。共提出3种不同的动态规划模型,分别为动态规划模型、优化选择动态规划模型与改进优化选择动态规划模型。算例分析充分验证了充电站动态规划方案的可行性与合理性 ...

Evolution and Phylogenetics of the Javan Hawk‐Eagle Nisaetus bartelsi (Stresemann, 1924) Using Mitochondrial Data 爪哇鹰雕 Nisaetus bartelsi (Stresemann, 1924) 基于线粒体数据的演化与系统发育研究

open access: yesIntegrative Conservation, EarlyView.
This study reconstructs the phylogeny of the Javan Hawk‐Eagle (Nisaetus bartelsi) within the subfamily Aquilinae using Maximum Likelihood and Bayesian Inference algorithms on a blood sample and GenBank data. The analysis reveals that the sampled genus Nisaetus forms a monophyletic group. Furthermore, N. bartelsi occupies a sister‐taxon of N.

Intangible drivers of tolerance shape human–elephant coexistence in Southwest China

open access: yesPeople and Nature, EarlyView.
Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant

A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

open access: yesWildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.

Anecdotes or Ecological Patterns: Symbiotic Foraging Behaviors in Coyotes and Badgers 奇特模式还是生态格局: 郊狼与獾的共生觅食行为

open access: yesWildlife Letters, EarlyView.
Using a 3‐year, broad‐scale camera‐trap network in western Kansas, we tested whether coyotes and American badgers exhibit spatiotemporal patterns consistent with coordinated hunting. Despite high diel activity overlap, detection‐conditioned co‐detections occurred far less frequently than expected under independence, and short‐term temporal sequencing ...
