Abstract The disjunctive distribution (Europe-Caucasus-Asia) and species diversification across Eurasia for the genus Allium sect. Daghestanica has fascinating attractions for researchers aiming to understanding the development and history of the modern Eurasia flora. However, no any studies have been carried out to address the evolutionary history of this section. Based on the nrITS and cpDNA fragments (trnL-trnF and rpl32-trnL), the evolutionary history of the third evolutionary line (EL3) of the genus Allium was reconstructed and we further elucidate the evolutionary line of sect. Daghestanica under this background. Our molecular phylogeny recovered two highly supported clades in sect. Daghestanica: the Clade I includes Caucasian-European species and Asian A. maowenense, A. xinlongense and A. carolinianum collected in Qinghai; the Clade II comprises Asian yellowish tepal species, A. chrysanthum, A. chrysocephalum, A. herderianum, A. rude and A. xichuanense. The divergence time estimation and biogeography inference indicated that Asian ancestor located in the QTP and the adjacent region could have migrated to Caucasus and Europe distributions around the Late Miocene and resulted in further divergence and speciation; Asian ancestor underwent the rapid radiation in the QTP and the adjacent region most likely due to the heterogeneous ecology of the QTP resulted from the orogeneses around 4–3 Mya. Our study provides a picture to understand the origin and species diversification across Eurasia for sect. Daghestanica.

Over the course of its history, design has never lost sight of nature as a term of comparison, sometimes taking from it, sometimes moving away from it. To investigate the complex relationship between the two terms, design and nature, we cannot ignore the evolution of man and how it has been profoundly influenced by technological innovation, which is the most evident result of science. Tracing an evolutionary line of design thinking, a double trajectory can be registered: on the one hand the tension towards progress and the myth of the machine, on the other hand the idea of a harmonious co-evolution with nature and the need to be reconnected with it. Besides, it is progress that allows mankind to thoroughly investigate natural mechanisms and make them their own. Contemporary design, autonomous but at the same time increasingly interdisciplinary, has got blurred boundaries which intersect with the most advanced fields of biological sciences. This evolution has opened up a whole new field of investigation that multiplies the opportunities of innovation, especially from a sustainability-oriented point of view. Today the dramatic breaking of the balance between man and nature has turned into the concept of permanent emergency, which is now matter of greatest interest for design, a design that attempts to react, mend, adapt to change in an authentically resilient way.


The biogeography of the subgenus is correlated with the morphological evolution of the species. From a source round the Coral Sea the subgenus has diversified into four evolutionary lines, namely sect. Pharmacosycea (America), ser. Nervosae (Indo-Pacific), ser. Vasculosae (Afro-Indo-Pacific) and ser. Austrocaledonicae (New Caledonia, Loyalty Islands, New Hebrides). The last in its isolation shows the pachycaul-leptocaul evolution. F. pseudojaca (New Guinea) is critical in this interpretation. F. smithii is removed to ser. Nervosae. F. pritchardii (Fiji) is removed to sect. Sycocarpus subsect. Papuasyce in alliance with F. microdictya , but this group may relate with ancestral Pharmacosycea . The species of ser. Austrocaledonicae are described and illustrated to show this unique evolutionary line: F. lifouensis (Loyalty Isl.) is described as new. In ser. Nervosae , in the alliance of F. pachysycia , two new species are described, F. homodroma and F. mesotes .

By using evidence derived from the relationships with smut fungi (Cintractia and Planetella) that attack its members, new light has been shed on the phylogeny of Carex. The genus is believed to be essentially monophyletic and derived from Kobresia. It has been found necessary to erect a new subgenus, Kuekenthalia, composed principally of those sections with persistent styles and bladdery perigynia that were formerly placed in Eucarex. Uncinia is shown to be an offshoot of the evolutionary line that gave rise to Kuekenthalia.

The southern Australian species of the tribe Crouanieae Schmitz (Ceramiaceae. Rhodophyta) have been studied with particular reference to their taxonomy relationships. and phylogeny; in all cases the type specimens have been examined. Three tribes. Crouanieae. Antithamnieae. and Heterothamnieae. can be recognized. including 16 genera. of which Euptilocladia. Macrothamnion. Tetuathamnion. Amoenothamnion. and Trithamnion are newly described and 48 species (26 newly described) . Recognition of the subfamilies Crouanioideae and Ceramioideae. as defined by Hommersand (1963). is not supported by these studies .Features of greatest taxonomic significance are those indicative also of phylogenetic trends and hence the classification is based upon concepts of phylogeny. Evolutionary advance in both morphological and reproductive features involves specialization, particularly towards adaptations in form with relation to function. The Crouanieae, Antithamnieae, and Heterotharnnieae are probably primitive groups of the Ceramiaceae. The Antithamnieae and Heterothamnieae are closely related and probably arose from the same evolutionary line, while Crouanieae has evolved independently. Thalli in the Heterothamnieae are smaller and less specialized than those of the most advanced species of Antithamnieae, and it is likely that the Heterothamnieae arose as a branch from the Antithamnieae line of development through specialization in reproductive features rather than thallus form. Both morphological and reproductive features are discussed and it is shown that Hommersand's definition of Antithamnieae must be modified, particularly in reference to procarp development. The probable phylogenetic lines revealed form useful bases for comparisons and provide a logical approach to the taxonomy of the group. Taxonomic features used in classification and reasons for the terminology adopted are also discussed. Analyses of records indicating the geographic distribution of species within southern Australia provide few useful conclusions.

AbstractLadinian deposits at Mt. Svilaja in Dalmatia (Outer Dinarides, Croatia) yielded an abundant brachiopod fauna of low diversity interpreted as a parautochthonous assemblage representing an ecosystem of dasycladacean submarine meadow. The fauna consists of four named species and one left in open nomenclature. The most common is the spiriferinideFlabellocyrtia flabellulumChorowicz and Termier, 1975 (Spiriferinida) accounting for more than 70% of the material. The athyridideCassianospira humboldtii(von Klipstein, 1845) is the only species known from elsewhere (Anisian of Southern Alps). The new species of SpiriferinidaThecocyrtella dagysiiHalamski, Bitner, Kaim, Kolar-Jurkovšek, and Jurkovšek n. sp. differs from other representatives of the genus in having a deep ventral sulcus.Albasphe albertimagniHalamski, Bitner, Kaim, Kolar-Jurkovšek, and Jurkovšek n. gen. n. sp. is a new brachiopod that possesses a dorsal septum with an intra-septal cavity and dorsal submarginal ridges, both features in common with AalenianZellaniaMoore, 1855 from which it differs in lack of the ventral septum and of ventral submarginal ridges. They are interpreted as members of a sparsely recorded paedomorphic evolutionary line of terebratulides with secondarily lost loop, described formally herein as Gwyniidina Halamski and Bitner n. subordo and subdivided into newly emended Dispheniidae Grant, 1988 (Dispheniinae Grant, 1988 with the only genusDispheniaand Albasphinae Halamski and Bitner n. subfam. withAlbaspheandZellania) and Gwyniidae MacKinnon, 2006 (including RecentGwyniaandSimpliciforma). In contrast to previous interpretations, the trocholophe lophophore ofGwyniais interpreted herein as secondarily simplified.

Abstract Being a reading performance turned into a stage representation, the text Iubirea la oameni (Human Love) signed by Dmitry Bogosvlavski is a love radioisotope into an oppressive cloister space of a Belarusian isolated community. The show with the same name created by Bogdan Sărătean surprises the stage valence of the emergence, the evolution and the extinction of this feeling, from the sacrificial love of a mother, which often conceals the faults and the sins of the children, to the brutal love that snatches what it believes as deserved, to the strength to believe in love as salvation, as redemption, as many forms to illustrate and to dramatically represent such an old theme, yet always different. The personal approach of the double distribution formed by the young 3rd degree actor students, probing their own interiority and sensibility, nuances and enhances the evolutionary line of characters’ destiny on stage in an extremely profound performance.

The functional reproductive system of three Mediterranean species of Coralliophilidae (Gastropoda: Prosobranchia), Coralliophila brevis, Coralliophila meyendorffii and Babelomurex cariniferus, was compared with that of Coralliophila squamosa and three Leptoconchus species. Differences chiefly in the pallial section of the female reproductive tract separate the Indo-Pacific genus Leptoconchus from the Mediterranean species, and subdivide the latter into three different anatomical groups. Polyphyly of the genus Coralliophila is suggested. Comparison of the reproductive system of coralliophilids with that of the related Muricidae allows identifying characters of Coralliophila brevis, Coralliophila meyendorffii and Babelomurex cariniferus that are unknown in Muricidae. The comparison also reveals a closer similarity of Coralliophila squamosa with Ocenebrinae, suggesting that this species might represent a less derived evolutionary line within Coralliophilidae. The reproductive system of some individuals of Coralliophila meyendorffii and Babelomurex cariniferus undergoing penis reduction in the laboratory is also studied. It sheds some light in the ontogeny of the female pallial reproductive tract, and provides direct evidence for the existence of protandry in these species.
