Land use change in farming-pastoral ecotone and its effects on ecosystem services value: A case study in West Jilin,China

This study analyzed the effects of land use change in West Jilin on ecosystem services value (ESV) in a long time scales (1976–2013) based on Pay Index. The results showed that the main characteristic of land use change in study area was area reduction in grassland and marsh, and area increase in arable land and alkali-land. However, land use change in Period 1 (1976–2000) got a faster rate than in Period 2 (2000–2013). The ESV in West Jilin mostly contributed by marsh, farmland, water, and grassland. The total value of ecosystem services increased from 21.65 billion yuan to 64.28 billion yuan during 1976–2013. Based on the Pay Index in 2013, ESV had an average annual reduction of 170.4 million yuan in Period 1, mainly caused by the conversion of marsh and woodland to other land use types. ESV in West Jilin lost about 115.02 million yuan per year in Period 2; the most important reason was that marsh converted to other types of land use. From the point of view of ecological service type, value of supporting service, regulating service, and cultural service was sustained or reduced both in Period 1 and in Period 2. However, the change of provisioning service value showed a slight upward trend during 1976–2013. Overall, land use change in West Jilin in recent 37 years lead to a continuous reduction in regional ESV, especially in Period 1.     

中国鳐类脑颅的研究

作者解剖观察了33种,隶于4目、7亚目、15科、19属的中国鳐类脑颅的形态。研究结果认为:锯鳐目和鳐目是原始类群,它们均具吻软骨,其中圆犂头鳐科和团扇鳐科是特化类群。电鳐目亦具吻软骨,它们是特化和退化类群。在较高等的鲼目则无吻软骨。依据鳐类不同的分类阶元,其脑颅亦各具有不同的式型。

Protaitzehoia Yang三叶虫分类位置的再研究-答“也论Protaitzehoia Yang三叶虫的分类位置”．．．

文章从三叶虫的头尾搭配问题的讨论对"也论Protaitzehoia Yang三叶虫的分类位置"一文中置于原太子河虫属的某些尾部的可靠性提出了质疑,认为插图2中的尾(K),由于缺少宽而下凹的尾边缘,应属于Stephanocare Monke,1903一属的尾部;插图2中的尾(L)的归属尚难定论.将原太子河虫属的头盖、活动颊、尾部、唇瓣与Cheilocephalus Berkey,1898属的头盖、活动颊、尾部、唇瓣对比后,认为原太子河虫属应归属Cheilocephalidae Shaw,1956.     

Spatial-typological differentiation of ecosystems of the west siberian plain. Communication III: Terrestrial invertebrates

The spatial distribution of the terrestrial invertebrate population of the West Siberian Plain is analyzed at the level of large functional groups (soil nematodes, annelids, microarthropods, mesoarthropods, snails, grass layer arthropods). Their air-dry biomass and roles in local ecosystems are estimated. The invertebrate population was classified in two ways: after averaging over units of the vegetation map of West Siberian Plain and after averaging over groups of units of this map. A digital thematic map of the invertebrate population is produced. Special features of the spatial heterogeneity of invertebrates were identified in correlation with the vegetation and humus distribution patterns. The biomass distribution of invertebrate groups is found to be less heterogeneous but more consistent with the distribution of natural zones.     

Trajectory modeling revealed a southwest-northeast migration corridor for fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae) emerging from the North China Plain

The fall armyworm Spodoptera frugiperda, an invasive insect pest native to the Americas, has established populations throughout eastern China. The North China Plain—a key corn-producing area in East China with a unique topography—was invaded by fall armyworm in 2019 and is seriously threatened by this migratory pest. However, the spatiotemporal extent of the migratory movements of fall armyworm from the North China Plain remains poorly understood. Using an air transport-based trajectory modeling approach that incorporates flight behavior, we simulated the potential nocturnal migration trajectories of fall armyworm from the North China Plain based on historical meteorological data from June to October of 2015–2019, and examined the night-time atmospheric conditions associated with their possible flights. The emigration patterns showed monthly variation in the main landing area and common migration direction. The displacement of newly emerged moths from the North China Plain was concentrated in the Northeast China Plain (including Liaoning, Jilin and Heilongjiang provinces) before late summer, after which they were most likely to undertake return flights to the south (especially into Hubei, Anhui and Hunan provinces). This southwest-northeast aerial migration corridor follows the topography of East China and is affected by the East Asian monsoon. These topographic-atmospheric conditions have resulted in the North China Plain becoming a key stopover for fall armyworm populations engaging in multigenerational long-distance migration across East China. These findings contribute to our knowledge of fall armyworm migration and will aid in the implementation of management and control strategies against this highly migratory agricultural pest.
