关键词： Cadmium;Transcriptomic;P. pseudoannulata;Cerebral ganglion

摘要： Cadmium (Cd) is a heavy metal that can cause irreversible toxicity to animals, and is an environmental pollutant in farmlands. Spiders are considered to be an excellent model for investigating the impacts of heavy metals on the environment. To date, the changes at the molecular level in the cerebral ganglia of spiders are poorly understood. Cd exposure leads to strong damage in the nervous system, such as apoptosis and necrosis of nerve cells, therefore we conducted a transcriptomic analysis of Pardosa pseudoannulata cerebral ganglia under Cd stress to profile differential gene expression (DGE). We obtained a total of 123,328 assembled unigenes, and 1441 Cd stress-associated DEGs between the Cd-treated and control groups. Expression profile analysis demonstrated that many genes involved in calcium signaling, cGMP—PKG signaling, tyrosine metabolism, phototransduction–fly, melanogenesis and isoquinoline alkaloid biosynthesis were up-regulated under Cd stress, whereas oxidative phosphorylation-related, nervous disease-associated, non-alcoholic fatty liver disease-associated, and ribosomal-associated genes were down-regulated. Here, we provide a comprehensive set of DEGs influenced by Cd stress, and heavy metal stress, and provide new information for elucidating the neurotoxic mechanisms of Cd stress in spiders. © 2018, The Author(s).

关键词： Metatranscriptome;Cadmium;Intestinal microorganisms;P. pseudoannulata

摘要： Cadmium (Cd) generates a variety of physiological and ecological toxicity to spiders. However, little is known about the effects of Cd on symbiotic bacteria of spiders. Metatranscriptomics is increasing our knowledge of microorganisms in environment. To better understand the impact of Cd on the symbiotic bacteria of spiders, we generated and compared the metatranscriptomes of the intestinal microorganisms of Pardosa pseudoannulata with and without Cd stress. The community structure of intestinal microorganisms in P. pseudoannulata was composed of 4 kingdoms, namely bacteria, viruses, eukaryotes and archaea, including 46 phyla, 97 classes, 184 orders, 339 families, 470 genera, and 598 species. The abundance of eukaryotes, bacteria and viruses was decreased by 0.14%, 1.22% and 2.52% respectively while the archaea was increased by 99.16% when under Cd stress. We identified 1519 differentially expressed genes (DEGs), including 770 up-regulated and 749 down-regulated genes. The results of KEGG annotation revealed that the expression of genes that are involved in the carbon metabolism, protein and amino acid metabolism and synthesis, glucose metabolism, oxidative phosphorylation, and glutathione metabolism were influenced by Cd. Collectively, these findings showed that Cd significantly impacted the community structure and expression of related functional genes of intestinal microorganisms in P. pseudoannulata. © 2018 Elsevier Inc.

关键词： Bioaccumulation;Metal pollution;Spiders

摘要： Heavy metals can accumulate in the bodies of spiders and affect their physiological and ecological traits and/or show toxicological effects. Spiders are thus considered to be potential bioindicators of heavy metal pollution for ecosystem monitoring, due to their superior resistance to and regulation of heavy metals. The metal loads in spider bodies show considerable variation within and among species, metal types, geochemical sites, exposure pathways, spider physiological traits, and other factors. Moreover, the mechanism of physiological regulation and tolerance in spiders to different kinds of heavy metals also varies significantly; it has been shown that those two differences are synergistic effects. Since the ecotoxicology and differences in physiological mechanisms remain unclear, questions and recommendations for possible further research are suggested.

关键词： Agricultural carbon emissions;Decoupling theory;Energy consumption;Livestock production;Multiple regression analysis;Principal component analysis

摘要： This paper estimates carbon emissions from agricultural production in China’s Hunan Province during the period from 1998 to 2012. It also analyzes trends in the development of agricultural carbon emissions and the decoupling relationship between carbon emissions and the agricultural output of Hunan. In this study, emissions from two key segments of the agricultural sector were quantified: (1) crop production and (2) livestock and poultry production (singular). A combined method of principal component analysis (PCA), multiple regression analysis, and decoupling analysis was employed to assess the drivers of agricultural carbon emissions. This showed that there was a weak and unstable decoupling relationship between agricultural carbon emissions and their output value during the period of study. The PCA revealed that two main factors—urbanization rate and nitrogen fertilization per acre—explained 92.51 % of the variation in the 11 factors that affected carbon emissions from crops. Also, two main factors (i.e., agriculture per capita GDP and the ratio of beef production to total livestock production) explained 86.27 % of the variation in nine factors that affected carbon emissions from the livestock and poultry industry. Using the PCA scores as independent variables, a multiple regression analysis of carbon emissions from the crop industry and the livestock and poultry industry showed the following patterns. (1) Theoretically, given a 10 % reduction in nitrogen fertilization per acre, crop carbon emissions would decrease by 519 units. If the rate of urbanization were to increase by 1 %, crop carbon emissions would increase by 83 units;(2) similarly, a 1 % reduction in the beef: total livestock and poultry production ratio would reduce carbon emissions from that industry by 329 units, and with “agricultural per capita GDP”growth of 1 unit, those emissions would increase by 0.354 units. The results of this study contribute to evaluating the sustainability of agricultural production in the region, and they provide a foundation of knowledge for future development of related agricultural mitigation policy and low-carbon agricultural technology. ©2015, Springer-Verlag Berlin Heidelberg.

关键词： Spiders;Bt rice;Non-target effects;GM crops;Spider ecology

摘要： Since the birth of transgenic crops expressing Bacillus thuringiensis (Bt) toxin for pest control, the public debate regarding ecological and environmental risks as well as benefits of Bt crops has continued unabated. The impact of Bt crops, especially on non-target invertebrates, has received particular attention. In this review, we summarize and analyze evidences for non-target effects of Bt rice on spiders, major predators in rice fields. Bt rice has been genetically modified to express the Bt protein, which has been shown to be transferred and accumulate in spiders as part of their food chain. Moreover, the Bt protein exhibits unintended effects on the physiology of spiders and spreads to higher trophic levels. Spiders possess unique physiological and ecological characteristics, revealing traits of surrogate species, and are thus considered to be excellent non-target arthropod model systems for study of Bt protein impacts. Due to the complexities of Bt protein transfer and accumulation mechanisms, as well as the apparent lack of information about resulting physiological, biochemical, and ecological effects on spiders, we raise questions and provide recommendations for promising further research.

关键词： Cadmium;Innate immunity;P. pseudoannulata;Transcriptomic;Venom glands

摘要： Due to some similarity of innate immunity between insects and mammals, the study of the molecular mechanism of innate immunity in insects has become a focus of research. However, the exact molecular and cellular basis of immune system in insect remains poorly understood. Characterization of the transcriptomic response to Cd of spider is an effective approach to understanding the innate immunity mechanisms. In this study, we carried out transcriptome sequencing and gene expression analyses to develop molecular resources for Pardosa pseudoannulata venom glands with and without Cd treatments. A total of 92,778 assembled unigenes and 237 Cd stress-associated differentially expressed genes between the Cd-treated and control groups were obtained. Expression profile analysis demonstrated that immunity-related genes involved in bacterial invasion of epithelial cells, leukocyte transendothelial migration, platelet activation, apoptosis, phagosome, and Rap1 signaling pathway were upregulated by Cd exposure, except the genes involved in PPAR signaling pathway were downregulated. Our results provide the first comprehensive transcriptome dataset of venom glands in P. pseudoannulata response to Cd, which is valuable for throws light on the immunotoxicity mechanism of Cd, and the innate immunity complexity.

关键词： *China;*predation function;*rice field spider;*study advances

摘要： Many laboratory and field studies have been conducted on rice field spiders in China. There are 375 species, 108 genera, and 22 families of rice field spiders distributed within the major rice growing areas and 17 dominant species. The biological and ecological characteristics of 17 rice field spider species have been reported in detail. The biology and ecology of these species show significant differences among regions, farmland habitats, and agricultural practices. Future research should focus on rice field habitat diversity, enhancing the insecticide resistance of dominant spider populations, implementing large-scale breeding of spiders and augmentative release, breeding more leaf dominant species, conducting biosafety assessment of spiders in transgenic crops.

摘要： 为探究湖南省农村集体土地拆迁补偿的现状和影响因素,利用湖南省304份集体土地拆迁的问卷调查数据,采用多元Logistic回归方法进行分析。结果表明:湖南省拆迁的认知度较低,主要表现为相关政策与法律法规宣传不够;政府行为与政策的透明度较低,主要表现为补偿标准制定不合理、硬性安置;拆迁补偿总体满意度较低,主要表现为补偿不公平、安置后的生活保障不足。对此,提出了修订补偿标准、公开补偿程序、增加补偿方式、推进拆迁立法等对策。并具体就补偿价值市场化提出:土地补偿价值可根据城市居民消费价格指数(UCPI)与农村居民消费价格指数(RCPI)来协同调整,而房屋拆迁补偿价值可根据城市居民消费价格指数(UCPI)与商品零售价格指数(RPI)协同调整的建议。

摘要： 油菜叶片图像中主叶脉的去除是进行油菜叶片氮营养诊断的基础。经典的植物叶片叶脉提取算法由于不同程度地利用了叶片表面细节特征,不适合于实时性要求较高的油菜叶片营养诊断处理。为此,提出了一种基于RGB颜色空间的快速去除油菜叶片图像主叶脉的快速截留超绿—超红新算法。实验结果表明,提出的快速截留超绿—超红算法不仅能够准确、有效、完整地清除出油菜叶片的叶脉部分,同时能够有效地去除叶面上的污点、黄化部分以及虫咬痕迹。通过油菜叶色特征与叶片SPAD值相关性分析发现,清除主叶脉后的油菜叶片图像颜色特征对油菜叶片氮营养诊断更有效。
