Элементы рецепции античных мениппей в повести А. Битова «Ожидание обезьян»

Екатерина Буханова
Статья выявляет творческую рецепцию античных жанровых моделей авантюрно-бытового романа-путешествия и менипповой сатуры, а также образных систем текстов Петрония, Апулея, Лукиана и других античных писателей в повести А. Г. Битова «Ожидание обезьян» (1993). Сатирический модус, утопическая фантастика и диалектика «сократического диалога» рассмотрены как способы проверки автором не только современной культуры, но и культуры в соотношении с онтологией, ее возможностей хранить духовную память человечества, определять способ существования человека. Интеллектуальный пафос повести скрыт и приближен к профанному читательскому...

Aleksander V. Gerasimov, Leonid A. Igumnov & Anatoliy M. Bragov
Numerical studies of the behavior of combined barriers consisting of solid and porous materials were carried out during high-speed impact on them with thin plates. It is shown that the introduction of plates of porous materials into the composition of combined barriers can significantly reduce the amplitude of compression waves and reduce the likelihood of spall damage. Comparison of the results of numerical modeling of high-speed impact interaction processes with the experimental results of other...

Судьба текста в романе А. Битова «Преподаватель симметрии»

Екатерина Буханова
Статья посвящена выявлению в романе А. Битова «Преподаватель симметрии» концепции текста как экзистенциального феномена, функционирующего в процессе создания и при рецепции заложенных в нём смыслов. Альтернативные возможности текста концептуализировались Битовым как способ понимания бытия, закрепления авторских концепций в культуре, а также возможность их тиражирования, неизбежного искажения и профанирования. Определяются формы изменения авторского замысла при воплощении его в тексте и формы жизни текста в культурной традиции. Ключевые слова: А. Битов «Преподаватель симметрии», текст, рецепция, эволюция авторского...

Evidence for niche conservatism in alpine beetles under a climate-driven species pump model

Jillian Schat, Yi-Ming Weng, Roman Dudko, David Kavanaugh, Lan Luo & Sean Schoville
Aim Past glacial climate cycles have generated lineage diversity in alpine habitats, acting as a climate-driven species pump. It is not clear how much this process contributes to ecological diversification of alpine species. To examine this problem, we test patterns of genetic and phenotypic divergence in two co-distributed species complexes of flightless alpine ground beetles. Greater differentiation in ecologically-important functional traits would indicate that ecological selection is an outcome of oscillating climate change, whereas greater...

Data from: Geographic variation of life-history traits in the sand lizard, Lacerta agilis: testing Darwin's fecundity-advantage hypothesis

Evgeny S. Roitberg, Galina V. Eplanova, Tatiana I. Kotenko, Fèlix Amat, Miguel A. Carretero, Valentina N. Kuranova, Nina A. Bulakhova, Oleksandr I. Zinenko & Vladimir A. Yakovlev
The fecundity-advantage-hypothesis (FAH) explains larger female size relative to male size as a correlated response to fecundity selection. We explored FAH by investigating geographic variation in female reproductive output and its relation to sexual size dimorphism (SSD) in Lacerta agilis, an oviparous lizard occupying a major part of temperate Eurasia. We analysed how sex-specific body size and SSD are associated with two putative indicators of fecundity selection intensity (clutch size and the slope of the...

Data from: Latitudinal environmental niches and riverine barriers shaped the phylogeography of the central Chilean endemic Dioscorea humilis (Dioscoreaceae)

Juan Viruel, Pilar Catalán & José Gabriel Segarra-Moragues
The effects of Pleistocene glaciations and geographical barriers on the phylogeographic patterns of lowland plant species in Mediterranean-climate areas of Central Chile are poorly understood. We used Dioscorea humilis (Dioscoreaceae), a dioecious geophyte extending 530 km from the Valparaíso to the Bío-Bío Regions, as a case study to disentangle the spatio-temporal evolution of populations in conjunction with latitudinal environmental changes since the Last Inter-Glacial (LIG) to the present. We used nuclear microsatellite loci, chloroplast (cpDNA)...

In this paper, we complete the syntaxonomical scheme for halophytic vegetation and adjoining plant communities of the lowland, montane and alpine zones in the Pamir-Alai and western Tian Shan in Tajikistan and Kyrgyzstan with some remarks on its environmental predictors. A total of 217 relevés were sampled in 2014–2019 using the seven-degree cover-abundance scale of the Braun-Blanquet approach. Modified TWlNSPAN was used to classify plant communities based on species composition. The cover-abundance scale was transformed...

Biogeographic diversification of Eranthis (Ranunculaceae) reflects the geological history of the three great Asian plateaus

Kun-Li Xiang, Andrey S. Erst, Jian Yang, Huan-Wen Peng, Rosa Del C. Ortiz, Florian Jabbour, Tatyana V. Erst & Wei Wang
The evolutionary history of organisms with poor dispersal abilities usually parallels geological events. Collisions of the Indian and Arabian plates with Eurasia greatly changed Asian topography and affected regional and global climate as well as biotic evolution. However, the geological evolution of Asia related to these two collisions remains debated. Here, we used Eranthis, an angiosperm genus with poor seed dispersal ability and a discontinuous distribution across Eurasia , to shed light on the orogenesis...
