蝴蝶优化算法对大青杨生长速率预测模型的改进

为提高大青杨生长速率的预测精度,提出一种基于改进的蝴蝶优化算法（Improved Butterfly optimization algorithm,IBOA）与径向基函数（Radial basis function,RBF）神经网络结合的预测木材材性方法。通过使用佳点集法对标准蝴蝶算法中的种群进行初始化,将自适应切换频率和Levy飞行相结合进一步优化人工蝴蝶算法。构建出了新的IBOA-RBF神经网络木材材性预测模型,将得到的结果与其他几种算法优化的RBF神经网络预测结果进行对比。结果表明：基于IBOA-RBF神经网络模型预测效果最好,收敛速度从37步降低到了23步,预测结果误差达到了5.72%,预测精度最高。可见,对蝴蝶算法的改进是可行的,且对相关人员定向培养大青杨起到较大的帮助。     

XVII.—Eine neue limacodide von Uganda (Lep.)

Intusatrium berryi sp. nov. and Holorchis sprenti sp. nov. are described from the gut of Sillago ciliata, S. maculata and S. analis from Deception Bay, Queensland. Intusatrium berryi is distinguished from its congeners by egg-size, the position of the genital pore, the size of the cirrus-sac and the lobation of the gonads. Intusatrium is retained as a valid genus despite the fact that its original diagnostic character was misinterpreted. It is suggested that I. robustum and I. secundum may prove to be synonymous. Holorchis sprenti can be distinguished from its congeners by the position of the ovary near the middle of the uterine field and by its smaller size.

选择“过失”：梁祝故事的经典化及其悲剧美学意义探析

梁祝故事在长期流传的过程中,对于其爱情悲剧的原因产生了多种解释和异文,其中流传较广的有命运早定说、社会原因说和误期说三种。在梁祝故事不断发展和经典化的过程中,命运早定说被取缔,社会原因说的内容随着社会政治的发展不断被更改,而误期说则被一直保留并得到强化。误期说从＂性格＂和＂偶然＂的角度来表现梁祝悲剧,肯定主要人物的＂过失＂是造成悲剧的重要原因,这使梁祝爱情悲剧更具普遍性和超越时空的感染力,它体现了梁祝故事经典化的必然要求。

A review of red-eye pigmentation and diel activity patterns in skippers (Lepidoptera,Papilionoidea, Hesperiidae)

ABSTRACT

The visual systems and diel activity patterns of butterflies and moths have been studied for decades, yet understanding the underlying mechanisms that are associated with the evolution of these remains a major challenge. The order Lepidoptera is principally composed of nocturnal lineages with extreme morphological and behavioural adaptations to this lifestyle. Although most butterflies are diurnal, some clades are predominantly nocturnal, for instance, the Hedylidae. Skippers are another family that comprises multiple crepuscular and/or nocturnal lineages. Interestingly, many such lineages have red-eye pigmentation, and this morphological feature has been hypothesised to be an adaptation to the night-time lifestyle. Here, we review the occurrence and frequency of red-eye pigmentation as well as diel activity patterns in Hesperiidae. We place these data within a phylogenomic framework and provide hypotheses and predictions relative to the evolution of red-eye pigmentation in skippers with respect to diel activity. We suggest that several types of red-eye pigmentation exist in skippers, with possible structural red-eye pigmentation in some lineages of diurnal skippers. The colouration of eyes in Hesperiidae, the evolutionary mechanisms that drive these traits and the physiological underlying processes require further attention and could bring new insights into our understanding of butterfly vision systems.
