A New Fossil Termite (Isoptera,Stolotermitidae,Stolotermes) from the Early Miocene of Otago,New Zealand

The forewing of a termite from Early Miocene lake sediments in Otago, southern New Zealand is figured and described. It exhibits the generic characters of the damp-wood termite Stolotermes Hagen, but differs from forewings of the known species in size and venation pattern and is described as Stolotermes kupe sp. nov. S. kupe represents the first confident record of fossil Stolotermitidae and extends the fossil record of the family back to the Early Miocene. It also is the first direct evidence of fossil Isoptera from New Zealand, though silicified termite faecal pellets, referable to Kalotermes brauni, have been previously described. S. kupe indicates that Stolotermitidae has been present in the Australasian region since at least the Early Miocene.

New fossils of the Early Pleistocene Equus huanghoensis(Equidae,Perissodactyla)from Nihewan in Hebei Province of China

This paper describes new fossils of Equus huanghoensis from an Early Pleistocene bed in Nihewan, Hebei Province, which confirms the classification of E. huanghoensis by Chinese researchers. The new fossils include a relatively complete male skull and mandible with all upper and lower dentition, a broken female skull with fragment of mandible and a broken Mc III of Equus sp. The fossils were collected from the Yangshuizhan site of Nihewan. The age of the formation is about 1.6 Ma. The new materials verify some classification characteristics based on teeth published in previous descriptions. These characteristics include large teeth size, short protocone, and tilted protoloph and metaloph. We have added to these characteristics of large skull size, a developed protuberantia supramagna, pentagonal nuchal side, weak Pli cabaline, simple enamel plications; a series of new characteristics strikingly different from the other Equus horses. The broken Mc III is similar to Equus qingyangensis from Qingyang, Gansu.

New Jurassic Fossil True Bugs of the Pachymeridiidae(Hemiptera:Pentatomomorpha)from Northeast China

Four new fossil genera and species of true bugs from the family Pachymeridiidae, Beipiaocoris multifurcus, Bellicoris mirabilis, Nitoculus regiUus, and Viriosinervis stolidus, are described. New specimens were collected from the Middle and Upper Jurassic non-marine sedimentary strata from the Jiulongshan and Yixian Formations of northeast China. The species Karatavocoris asiatica Becker-Migdisova, 1963, which was considered to be a member of the family Coreidae is transferred to the Pachymeridiidae. A new map of all known and newly discovered fossil pachymeridiid localities is given. The diagnosis of the family is modified.

New Genus and Species of Fossil Dragonflies (Insecta: Odonata) from the Yixian Formation of Northeastern China

Two well-preserved fossil dragonflies from the Late Mesozoic Yixian Formation, Liaoning Province, China are described and assigned to a new genus, Sopholibellula gen. nov. in Araripelibellulidae Bechly, 1996, closely related to the type genus Araripelibellula. This new genus differs from AraripelibeUula in the following characters： origins of RP and MA distinctly separated at arculus in both pairs of wings; anal loop wider and shorter, with Y-shaped veins inside; MA and IR2 not zigzag; several small intercalary veins present in the postdiscoidal area of hindwing; cells smaller and much more dense, especially in the apex and hind margin; bigger in size. Structures, including head, abdomen and parts of legs, were first described in details of this family.

Significant New Dinosaur Egg Fossils Discovered in 2017

1 Dinosaur Eggs in Yiwu City, Zhejiang Province In February 2017, dinosaur egg fossils were discovered in China Town part of Yiwu City, Zhejiang Province. They were confirmed by dinosaur experts from the Zhejiang Museum of Natural History to be those of Mesozoic herbivorous dinosaurs （Fig. 1）. Not long before, Yiwu Museum staff had discovered dinosaur eggs close by this place.

New fossil mayflies （Insecta： Ephemeroptera） from the Middle Jurassic of Daohugou, Inner Mongolia, China

Abstract Jurassonurus amoenus, a new genus and species of Siphlonuridae s. I. is described from the Middle Jurassic Jiulongshan Formation of the Daohugou Village, Shantou Township, Ningcheng County, Inner Mongolia, China. The new species is estab- lished by more than 20 imago and subimago specimens in relatively good condition. Detailed description and illustration of the specimens along with a review of fossil Siphlonuridae s. I. are given. Comparing with two known dominant nymph species Fuyous gregarious Zhang and Kluge, 2007 and Shantous lacustri Zhang and Kluge, 2007 from the same locality, we could not find any relationship among them. The new species is another dominant species in Daohugou beds.

New fossil eccoptarthrids (Coleoptera: Curculionoidea) from the Yixian Formation of western Liaoning, China

One new genus and three new species of the weevil family Eccoptarthridae (Curculionoidea), Leptocar polychaetus gen. et sp. nov., Abrocar macilentus sp. nov., Cretonanophyes punctatus sp. nov., are described and illustrated. They pertain to the Upper Jurassic or Lower Cretaceous Yixian Formation of western Liaoning Province, China. The host plants to the living eccoptarthrids and the floras in Yixian Formation indicate that those archaic eccoptarthrids possibly lived on conifers with a phylogenetic closeness to Cupressaceae. Besides, the early diversification of eccoptarthrids is discussed: origi- nated in Central or East Asia in the Late Jurassic, spread into Western Europe and South America during the Early Cretaceous, underwent a dramatic decline after the Early Cretaceous which likely was caused by competitive pressure and the displacement of their host plants.

Research on the Impact of New and Renewable Energy Replacing Fossil Energy Resource under Constraint of Carbon Emissions

For studying new and renewable energy as a substitute for fossil energy in primary energy consumption and its impact on carbon emissions to cope with economic uncertainties, a multi-sector DSGE model was employed to simulate the dynamic impact on carbon emissions and macroeconomic development. The structural adjustment of energy consumption and the carbon emissions mitigation policy were considered in the model. The simulation results showed that using new and renewable energy instead of fossil energy is an optimal choice for the firms to comply with the regulations of carbon emission mitigation policy. Structural adjustment of energy consumption is the best route to achieve the dual goal of economic development and carbon emission reduction. Unexpected sharp fall in free carbon quota has a negative impact on the economy.

Many New Dinosaur Fossil Spots Discovered in the Dunhuang-Yumenguan-Jiuquan Area of Gansu Province, China

New Jurassic Pseudopolycentropodids from China (Insecta: Mecoptera)

In this paper two new species of fossil Pseudopolycentropus Handlirsch, 1906 are described： Pseudopolycentropus janeannae sp. nov. and P. novokshonovi, sp. nov. All of them were recovered from the Middle Jurassic non-marine sedimentary strata of northeastern China. The new material from China reveals that the early diversification of pseudopolycentropodids was well underway by the Middle Jurassic.

A New Species of the Family Juraperlidae (Insecta:Grylloblattida) from the Middle Jurassic of China

Juraperla grandis sp. nov. （Grylloblattida： Juraperlidae） is described from the Daohugou locality （Middle Jurassic, China）. Its wing venation is very similar to that ofJuraperla daohugouensis Huang and Nd, 2007 （Grylloblattida： Juraperlidae）, in the particular occurrence of a supplementary longitudinal vein in the area between the anterior wing margin and ScP. The larger size of the new specimen, the lower number of CuA1 branches, and the occurrence of two rows of cells between MP and CuA in forewings justify the erection of a new species, J. grandis sp. nov.. The material also preserved hind wing and body structures, described for the first time in Juraperlidae.

A New Subfamily of Aphids (Hemiptera,Aphidomorpha) from the Early Cretaceous Lebanese Amber with a Description of the Oldest Apterous Morphs

Aphids are marked by their high polymorphism, but species reported from the Early Cretaceous are known only from alate morphs. The discovery of an apterous adult morph in Lebanese amber and a larva of the same species are very important for the understanding of both the morphological and biological evolution of this insect group at the very early stage of development. Gondvanoaphis estephani new subfamily, new genus and species of the recent aphids family Thelaxidae is described. The characters of the new genus in respect to other genera placed in Thelaxidae are reviewed. The palaeoeeological and palaeogeographical data concerning Gondvanoaphis new genus are also discussed.

2023年美国能源政策展望

美国拜登政府对特朗普时期的能源政策进行了大量修正和否定,以促进清洁能源发展。2022年中期选举后,在拜登政府的后半任期内,民主党的能源低碳化措施将面临阻力,但前期通过的法案和财政支持仍将发挥作用,能源政策的区域分化更加明显。2023年,俄乌局势将成为影响拜登能源政策的最大不确定性因素,美国能源转型进程将有所放缓。美国或将在新能源领域出台保护主义政策,会对欧洲能源转型造成巨大阻碍,同时围绕跨大西洋联盟形成能源领域技术保护壁垒,对其他国家进行打压。
