Further connections between the benthic marine algal floras of the northern Arabian Sea and Japan

Identifications made on some recent collections of benthic marine algae from the Sultanate of Oman, northern Arabian Sea, have revealed several new records for this region. A total of eight species, representing five species of Rhodophyceae, two species of Phaeophyceae, and a single species each of Chlorophyceae, are newly reported for Oman. Of particular interest is the fact that these species represent new records for the Indian Ocean, some of which had previously been known from Japan and environs.     

Observations on the formation of Chinese desert floras

1. Based upon the analyses in the floristic elements of the three genera (Suaeda, Salsola and Zygophyllum) in different regions we can see that the genesis of our desert floras in these regions is very much diversified. The flora of Songaria is similar to that of the Middle Asia, while the Hosi Corridor seems to be a transitional area very close to Alashan and also related to the Tarim Basin in floristic elements. Thus, we may classify the desert floras into three parts: the flora of Songaria, of Alashan including the Hosi Corridor and of the Tarim Basin including the Tsaidam Basin. The ages and approaches in their formation are different. 2. There are plenty species but no or rare endemics in Songaria. In spring there are a number of ephemeral plants. The variation of aspect is evident. The vegetation cover is abundant. The floristic elements are developed from the flora of Middle Asia and it was formed in Quaternary period. 3. The floristic elements of the Tarim Basin are poor, but there are not few endemics and the distribution of the endemics is much limited. They are of the characteristics of relic species. Therefore it was formed in the Tertiary period and developed in Quaternary period. The elements are related to the Mediterranean flora. 4. There are a large number of endemics and many endemic monotypie genera in Alashan. They represent the flora formed in Tertiary period. Although it is of a special style, it relates both to the Middle-Asian and the Mediterranean flora. 5. The historic causes for the formation of the different floras lie chiefly on: (1) The rise of the Tibetan plateau and mountains strongly changed the climatic and edaphic conditions and in the long course of evolution some species survived or even developed, while the others deteriorated or even died out from the flora. (2) Because the circumstances of transgression or regression of the Tethys were different in these regions. (3) The mountain-making movement, the transgression and regression and the fluence of glaciation, all the mutation of these associated factors modified the climatic zonation and then the plant species changes followed, new species formed and migration of floristie elements occurred. (4) Songaria is the nearest region to the then Sibirian glacier, so the frozen injury to the flora might be the greatest. (5) In the Glacial period the descension of snow line in Songaria was greater than that of the Tarim Basin, so the frozen injurymight be greater.     

Microbial gut floras of eight species of tephritids

The gut bacteria of eight tephritid species were isolated and characterized. Larvae of the genus Urophora and Tephritis dilacerata proved to house no microorganisms in their digestive organs. Bacteria were isolated from adults of five fruit fly species. Most of the bacterial strains were enterobacteria. Fruit-infesting tephritid species, flower-head species and gall formers had similar gut floras consisting of bacteria widespread in the soil and on the phylloplane.

Transit towards floristic homogenization on oceanic islands in the south-eastern Pacific: comparing pre-European and current floras

Aim  To quantify the occurrence of processes of homogenization or differentiation in the vascular flora of six oceanic islands.
Location  Six islands in the south-eastern Pacific drawn from the Desventuradas Archipelago, Easter Island and the Juan Fernández Archipelago.
Methods  Using published floristic studies, we determined the floristic composition of each island at two different stages: (1) pre-European colonization and (2) current flora. We compared changes in the number of shared plants and the floristic similarity among islands for each stage.
Results  The number of plant species doubled from 263 in pre-European flora to 531 species currently. Only three native species became extinct, four natives were translocated among the islands and 271 plant species were introduced from outside. The frequency of plant species shared by two or more islands is higher in the post-European floras than prior to European contact, and the level of floristic similarity between islands increased slightly.
Main conclusions  Considering the low naturalization rate of alien plants, the small number of extinctions and the meagre increase in floristic similarity, these islands are undergoing a slow process of floristic homogenization.     

A comparison between the Upper Triassic floras of China and the Rhaeto-Liassic floras of Europe and East Greenland

A survey is given of the geological and geographical distribution of the Upper Triassic floras of China, based chiefly on many articles published in Chinese during the last ten years. This is followed by a comparison between the Upper Triassic flora of China and the Rhaeto-Liassic floras of Europe (Sweden, Germany) and East Greenland. It is pointed out that important floral assemblages (for example that of the Liassic Thaumatopteris schenkii Assemblage-zone) occur considerably earlier in China (especially in S.W. China) than in Europe and East Greenland.     

Investigating the evolution of floras: problems and progress — An introduction

The Cape flora of southern Africa is a remarkable hotspot for plant species diversity and endemism. At a meeting in Zurich in 2004 progress in understanding the evolution of this diversity was reviewed. In this symposium, four papers presenting several of the methods used in this investigation were reported. These papers deal with molecular dating methods, the reconstruction of ancestral habitats, with possible speciation scenarios for the Cape flora, and the importance of the correct sampling strategies.

Callistophytalean pteridosperms from Permian aged floras of China

Abstract: Recent investigations into Permian aged floras from China have highlighted the widespread occurrence of callistophytalean pteridosperms that challenge previous understanding of their spatial and temporal distribution and diversity. In China, the group spans the Permian period and constitutes a distinctive but rare component in many peat‐forming environments. The stratigraphically earliest callistophytalean occurs in the Asselian‐Sakmarian stages with fossils from the Taiyuan Formation of northern China including ovules of Callospermarion undulatum in coal ball assemblages, and ovulate fronds of Norinosperma shanxiensis and synangiate fronds of Norinotheca shanxiensis in adpression assemblages. More abundant in the fossil records are adpression remains from the Roadian‐Wordian stages with the Lower Shihhotse Formation preserving abundant vegetative and ovulate remains of Emplectopteris triangularis that is now considered to represent a callistophytalean. The youngest callistophytalean recognised is from the Wuchaipingian‐Changhsingian stages with the Xuanwei Formation of southern China containing a single stem of Callistophyton boyssetii that provides indisputable evidence of the group in the lead up to the end‐Permian mass extinction. These accounts are augmented by analysis of pollen records that demonstrate the callistophytalean pollen genus Vesicaspora to be widespread through palynological assemblages from the Permian period in both North and South China, including the Upper Shihhotse Formation, Shihchienfeng Group, Xuanwei Formation, and possibly also in the mid‐Pennsylvanian Benxi Formation. Although macrofossil specimens are uncommon elements in the assemblages that contain them, they demonstrate the continuity of callistophytalean pteridosperms from the Pennsylvanian sub‐period into the early Guadalupian epoch of the Permian in North China and into the Lopingian epoch of the Permian in South China. Of the species present, both Callistophyton boyssetii and Callospermarion undulatum are known from the Pennsylvanian–earliest Permian age floras of Euramerica, whereas Norinosperma, Norinotheca and Emplectopteris appear to represent endemic Cathaysian elements. Results imply that callistophytalean pteridosperms can no longer be excluded from theories of post‐Carboniferous plant evolution and floristics, appearing to have played an important role in both Permian and Carboniferous aged plant communities. The presence of Vesicaspora in several formations from which macro‐remains have not been identified is a hopeful indicator that further callistophytalean pteridosperms are yet to be found.
