1A New Species of Phoenicopsis Subgenus Windwardia(Florin) Samylina(Czekanowskiales) from the Middle Jurassic of Inner Mongolia, China显示文摘A new species of Phoenicopsis subgenus Windwardia(Florin) Samylina, Phoenicopsis neimengguensis sp.nov., is recognized from the Middle Jurassic Zhaogou Formation in the Shiguai Basin, a Jurassic coal-bearing sedimentary basin in Inner Mongolia, China. Linear leaves are in bundles of six to eight and are attached on a short shoot. The leaf is amphistomatic with one or two irregular rows of longitudinally oriented stomata in each intercostal zone on the upper epidermis and three or four(occasionally six) rows of stomata in each intercostal zone on the lower epidermis. Each stomata is surrounded by four to six subsidiary cells with unevenly developed papillae. The anticlinal walls of epidermal cells are straight. Cuticular thickenings or papillae are present on the outer surface of the periclinal walls. This is the first time that Phoenicopsis subgenus Windwardia(Florin) Samylina is recognized from the Middle Jurassic of Inner Mongolia, China. The occurrence of the new species is noteworthy because it extends the geological and geographic distribution of Phoenicopsis subg. Windwardia in China and Eurasia. The discovery is significant as it increases our knowledge of Phoenicopsis subg. Windwardia by providing new data on morphological and epidermal features.SUN Chunlin NA Yuling David L.DILCHER WANG Hongshan LI Tao LI Yunfeng 2015Acta Geologica Sinica(English Edition)2015,89,1:7

4Anomozamites(Bennettitales) from Middle Jurassic Haifanggou Formation,western Liaoning,China显示文摘The Middle Jurassic Hangfanggou Formation is well exposed in Shangsanjiao and Xiasanjiao villages area,Baimashi town of Huludao,western Liaoning,China.Recently,abundant fossil plants were collected from the Hangfanggou Formation.One new species,Anomozamites sanjiaocunensis sp.nov.(Bennettitales),is described in this study.This is the first report of the genus Anomozamites from the Haifanggou Formation based upon the leaf morphology and epidermal structures.The discovery of the new species extends significantly the stratigraphic and geographic distribution of Anomozamites in the Middle Jurassic.It also shows that Anomozamites was a common member of Bennettitales once lived in the Middle Jurassic warm temperate region.The new species also improves the knowledge on understanding the leaf morphology,epidermal features and the diversity of Anomozamites during the Middle Jurassic.The epidermal characters of the new species and its associated plants reveal that the plants grew in a warm and moderately humid environment in the warm temperate zone.The presence of some deciduous plants,such as ginkgoaleans,czekanowskialeans and conifers,indicate the climate with seasonal fluctuations in temperature.ZHAO Miao SUN Chunlin David L.Dilcher ZHAO Zhe NA Yuling 2015Global Geology2015,18,2:3

11An introductory report on the biodiversity of Middle Jurassic Phoenicopsis(Czekanowskiales) from the Ordos Basin, China显示文摘Although the genus Phoenicopsis is the most common member of Czekanowskiales and is considered an indicative representative of the Middle Jurassic Coniopteris–Phoenicopsis assemblage in northern China, little was known about its taxonomy and biodiversity based upon the leaf cuticular structure. In this paper, three subgenera of the genus Phoenicopsis from the Middle Jurassic, Yan'an Formation of the Ordos Basin, China, Phoenicopsis(subg. Phoenicopsis)(Heer) Samylina, P.(subg. Windwardia)(Florin) Samylina and P.(subg. Culgoweria)(Florin) Samylina are identified based upon the leaf epidermal features for the first time. This discovery demonstrates that Phoenicopsis was quite diverse during the Middle Jurassic in northern China. Its biodiversity is significant for further understanding Middle Jurassic paleophytogeography and paleoclimatology of northern China. The current findings show that the three Phoenicopsis subgenera coexisted and flourished in the mixed zone(ecotone) between the Indo-Sinian Floristic Region and the Siberian Floristic Region as seasonal deciduous plants(trees or shrubs) during the Middle Jurassic. They were important elements in the Middle Jurassic deciduous gymnospermous forest community in warm temperate regions with seasonal temperature and precipitation variations. They are interpreted as growing on the hillsides and sloping fields along meandering streams, lakes and swamps in a vast sedimentary basin in a wet and warm environment.Chunlin Sun Yunfeng Li David L.Dilcher Hongshan Wang Tao Li Yuling Na Anping Wang 2015Science Bulletin2015,60,21:1

15Tree succession across a seasonally dry tropical forest and forest-savanna ecotone in northern Minas Gerais,Brazil显示文摘Aims Understanding succession in tropical forest is an important aspect of vegetation science,but to date,successional processes in sea-sonally dry tropical forests(SDtFs)have received much less atten-tion than evergreen humid tropical forests.We aim to fill this knowledge gap.Methods We investigated vegetation succession in SDtF areas consisting of three different successional stages(early,intermediate,late),and a SDtF-savanna ecotone in the municipal district of Juramento,north of Minas Gerais State,Brazil.Using twelve 400 m2 plots in each area,we compared vegetation parameters and structural variables(absolute density and basal area)and examined the floristic composition of the tree component to find gradients of change.Important Findings We found evidence of species turnover along a successional gradi-ent,with the intermediate stage showing the highest species rich-ness and diversity.this was accompanied with a significant increase in the number of tree individuals and basal area from the early to intermediate successional stage.However,the intermediate and late SDtF successional stages were more similar in structure and floristics.the ecotone was the most species rich and was similar to the intermediate SDtF and early successional stage in species richness and floristic composition respectively.these results will have implications for guiding SDtF management and recovery programs.Polyanne A.Coelho Paola Ferreira Santos Eduardo de Paiva Paula Deborah M.G.Apgaua Bruno Gini Madeira Gisele Cristina de Oliveira Menino Yule Roberta Ferreira Nunes Rubens M.Santos David Y.P.Tng 2017Journal of Plant Ecology2017,10,5:0
