2. A new genus of isophlebioid damsel-dragonflies with "calopterygid"-like wing shape from the Middle Jurassic of China (Odonata: Isophlebioidea: Campterophlebiidae)
- Creator:

- article, model:article, and TEXT
- Subject:
- Odonata, Isophlebioidea, Campterophlebiidae, gen. n., sp. n., Middle Jurassic, China, and wing shape
- Language:
- English
- Description:
- Zygokaratawia reni, a new campterophlebiid genus and species is described from the Middle Jurassic of China. This fossil has a wing shape unique for this clade, i.e. a fore- and hind wing of the same width and very shortly petiolated, and hind wing cubito-anal area nearly as narrow as that of the forewing. This wing shape is convergently similar to that of recent Zygoptera: Calopterygidae, as well as to several other Cenozoic zygopteran clades, suggesting similar styles of flight and habits, i.e. predation on small insects and flight along trees of river banks.

3. A new Middle Jurassic "grylloblattodean" family from China (Insecta: Juraperlidae fam. n.)
- Creator:
- Huang, Di-Ying and Nel, André
- Type:
- article, model:article, and TEXT
- Subject:
- "Grylloblattodea", Juraperlidae fam. n., Middle Jurassic, Daohugou, and China
- Language:
- English
- Description:
- The new family Juraperlidae is erected for the new genus and species Juraperla daohugouensis from the Chinese Middle Jurassic. Its wing venation has strong similarities with that of Mesozoic taxa currently included in the group "Grylloblattodea", but its character "three (or four?)-segmented tarsi" questions its potential inclusion into the same order with the modern Grylloblattodea. This suggests that the systematic assignments of several fossil "grylloblattid" species, mainly based on wing venation, could be very different.

- Description:
- Alkali stress is an important agricultural problem that affects plant metabolism, specifically root physiology. In this study, using two rice cultivars differing in alkali resistance, we investigated the physiological and molecular responses of rice plants to alkali stress. Compared to the alkali-sensitive cultivar (SC), the alkali-tolerant cultivar (TC) maintained higher photosynthesis and root system activity under alkali stress. Correspondingly, the Na+ content in its shoots was much lower, and the contents of mineral ions (e.g., K+, NO3-, and H2PO4-) in its roots was higher than those of the SC. These data showed that the metabolic regulation of roots might play a central role in rice alkali tolerance. Gene expression differences between the cultivars were much greater in roots than in shoots. In roots, 46.5% (20 of 43) of selected genes indicated over fivefold expression differences between cultivars under alkali stress. The TC had higher root system activity that might protect shoots from Na+ injury and maintain normal metabolic processes. During adaptation of TC to alkali stress, OsSOS1 (salt overly sensitive protein 1) may mediate Na+ exclusion from shoots or roots. Under alkali stress, SC could accumulate Na+ up to toxic concentrations due to relatively low expression of OsSOS1 in shoots. It possibly harmed chloroplasts and influenced photorespiration processes, thus reducing NH4+ production from photorespiration. Under alkali stress, TC was able to maintain normal nitrogen metabolism, which might be important for resisting alkali stress., H. Wang, X. Lin, S. Cao, Z. Wu., and Obsahuje bibliografii

- Description:
- Kniha si klade za cíl představit českému čtenáři situaci a vývoj katolické církve v Čínské lidové republice od jejího založení v roce 1949 až po současnost (2022). Vedle historického kontextu poskytuje také novodobé poznatky o čínských katolících. Zabývá se nejen různorodými skupinami katolíků, které se nacházejí na území Čínské lidové republiky a spadající do oficiálního, státem povoleného Vlasteneckého sdružení čínských katolíků, ale také věřícími v takzvané podzemní církvi, která není čínskými orgány povolena. Kniha popisuje politická a sociální dilemata, jimž církev čelí pod vedením Komunistické strany Číny. ,The book introduces the situation and development of the Catholic Church in the People's Republic of China from its foundation in 1949 to the present (2022). It provides both historical context and contemporary information about the Chinese Catholics. It examines the diverse groups of Catholics established in the territory of the People's Republic of China belonging to both the official state-run Chinese Catholic Patriotic Association and believers in the so-called underground church, which is not sanctioned by the Chinese authorities. The book examines the political and social dilemmas facing the church under the leadership of the Chinese Communist Party.

9. Cephalcia masuttii sp. n. (Hymenoptera: Pamphiliidae), a new web-spinning sawfly living on spruce
- Creator:

- Subject:
- Pamphiliidae, Cephalcia, new species, karyotype, allozyme analysis, Picea, Europe, and China
- Language:
- English
- Description:
- Cephalcia masuttii sp. n. is described from the SE Alps of Europe, based on morphological, biological, and genetic studies. The larvae feed gregariously on Picea abies. The species has been recorded also from Central Siberia and NE China, where the larvae feed on Picea obovata and Picea koraiensis, respectively. Indications exist that it may be more widely distributed in Europe and northern Asia. The strict gregariousness of larvae of this species is peculiar among spruce feeders of Cephalcia. Morphologically the adults are most similar to Cephalcia alashanica, with which they are compared. An allozyme analysis showed that the populations from Europe and China are quite similar and clearly different from the other species living on spruce. The karyotype of C. masuttii (n = 25) is also described.

- Description:
- Acid rain causes damages to forest ecosystems. Here, we reported that acid rain could promote plant growth. From 2006 to 2009, one-year-old Elaeocarpus glabripetalus seedlings were sprayed with simulated acid rain (AR) (pH 2.5, 4.0, and 5.6). The maximum quantum yield efficiency of PSII and the actual photochemical quantum efficiency of PSII increased with rising AR acidity, which facilitated chlorophyll fluorescence and plant growth, as shown by a declining minimal fluorescence yield of dark-adapted state with little damage to the PSII reaction center. After the second experimental year, the plant height and ground diameter were greater at pH 2.5 than those found at pH 4.0 and 5.6. This showed the positive effects of AR on the seedling growth and photosynthesis of E. glabripetalus, revealing that this species exhibited a stronger resistance to acid deposition than some other tree species. This implies that E. glabripetalus is an acid-tolerant species., M.H. Liu, L.T. Yi, S.Q. Yu, F. Yu, X.M. Yin., and Obsahuje bibliografii
