摘要: 蜘蛛作为蛛形纲中种类繁多、分布广泛、繁殖迅速且寿命长的生物群体,其生活习性呈现出丰富多样的特点.蜘蛛携带多种次生内共生菌,包括Wolbachia、Rickettsia、Cardinium和Spiroplasma等,这些共生菌在蜘蛛的多种组织中,特别是生殖系统中占据着重要地位,并发挥着不可忽视的作用.本文深入探讨了这些内共生菌的水平和垂直传播机制,揭示了它们对蜘蛛生殖调控的深远影响,如影响后代雌雄比例等.此外,次生内共生菌还在蜘蛛的营养摄取、扩散范围以及对外界压力的反应等方面展现出显著的影响能力.基于对相关文献的详尽梳理与分析,本文对蜘蛛及其次生内共生菌的研究现状进行了全面综述,并提出了未来的研究方向.

摘要: Here I explore the biological relevance, origin and meaning of the concept of cladogram (rooted, directed branching diagramsrepresentingthehypothesizedphylogeneticrelationshipsamongtheterminaltaxaunderstudy)andarguethat cladogramsdonotnecessarilyentailsynapomorphies,butsynapomorphiesarerequiredtotestandultimatelyfalsify cladograms. Both cladograms and synapomorphies are required to achieve phylogenetic explanation. I conclude that within aphylogenetic,scientificcontext,testabilityreferstothelogicalrelationshipamongcladograms(hypotheses),synapomorphies (evidence), and background knowledge (descent with modification). It is the relationship between evidence and hypothesis that underlies a logically consistent relationship between synapomorphies and cladograms. The capacity of a given cladogram, as a hypothesis, to explain synapomorphies complements this relationship and conforms phylogenetic explanation.

摘要: Ancient Lake Baikal(LB) is the prime hotspot of the harpacticoid diversity. The Canthocamptidae harpacticoids in the lake can be considered at least six species flocks. The lacks of unequivocal diagnostic characters in the family species description often lead species identification to an impasse. Recently developed molecular techniques provide a powerful tool to subject copepod taxa to comparative analyses. In order to provide a new base for canthocamptids taxonomy and clarify the systematic in some species flocks, we analyzed the mitochondrial DNA marker COI of 103 harpacticoid specimens from LB belonging to five genera. The materials were obtained from different lake basins from the depths 0.2-1632 m. Using DNA barcoding, we identified 23 genetic species or groups of species, it was almost 1.5 times less than number of morphological species, and divergence of some molecular lineages were not corresponding to morphological species. Results of our study were the discovery of a new species, males of some morphological species, for which only females were previously described, clarification of the level of morphological variability of some species, etc.Specifically, it became apparent that morphological and genetic harpacticoid species diversity in LB differ significantly and it has to be detected strictly in complex.

摘要: Mitochondrial genomes of five Tykhepoda scolopendromorphs(Cryptopidae,Scolopocryptopidae and Plutoniumidae) are sequenced and analyzed using methods of comparative genomics to provide more information on the phylogeny of Scolopendromorpha.The locations of 22 t RNAs, 13 PCGs, and 2 rRNAs are annotated. The heavy chain of mitochondrial genomes are 14,841–15,619 bp in length. A+T % vary from 64.79% to 77.40%,and mitochondrial genomes are CG and AT skewed. The phylogenetic reconstructions showed the blind clade, recently named Tykhepoda, is monophyletic with high support values(BS = 100%and PP = 1).

摘要: Two new species of the genus Trypoxylon, namely T. flavimaculatum Fu & Li, sp.nov. and T. tuberantennatum Fu & Li, sp. nov., are described and illustrated from Guizhou,Guangdong, Guangxi and Zhejiang Provinces, China. Another two species, T. chosenense Tsuneki, 1956 and T. konosuense Tsuneki, 1968, are newly recorded from China.
