山葡萄低温诱导酵母双杂三框cDNA文库构建和VaCIPK18互作蛋白筛选鉴定

类钙调磷酸酶B亚基蛋白CBL（calcineurin B-like protein）与其互作蛋白激酶CIPK（CBL-interacting protein kinase）组成的CBL-CIPK系统，在真核生物钙信号转导及各种胁迫应答途径中发挥重要作用。采用SMART与LD-PCR技术构建了山葡萄‘双丰’（Vitis amurensis Rupr. ‘Shuangfeng’）叶片组织低温胁迫下的均一化酵母双杂交三框cDNA文库，库容量分别为1.7 × 106、1.3 × 106与1.9 × 106 cfu • mL-1，外源基因插入片段长度约为500 ~ 2 000 bp，重组率为100%，符合后续双杂交筛选要求。以本课题组前期鉴定受低温诱导表达、具有核质亚细胞定位的山葡萄VaCIPK18全长（VaCIPK18）、激酶结构域缺失（VaCIPK18△S_TKc）以及NAF结构域缺失（VaCIPK18△NAF）为诱饵，进行酵母双杂交筛选，获得了17个候选互作靶蛋白；从中选取并克隆了7个参与非生物胁迫的候选互作蛋白进行酵母回转验证，仅发现1个ABA信号通路上游信号调节因子VaPYL9与VaCIPK18有互作关系。通过酵母双杂交和双分子荧光互补验证，确定了VaPYL9可与VaCIPK18和VaCIPK18△NAF在酵母中物理互作，而在植物拟南芥原生质体中VaPYL9与VaCIPK18△S_TKc和VaCIPK18△NAF互作，但与全长VaCIPK18不互作。     

Governance interactions in small‐scale fisheries market chains: Examples from the Asia‐Pacific

Small‐scale fisheries are subject to various governing institutions operating at different levels with different objectives. At the same time, small‐scale fisheries increasingly form part of domestic and international market chains, with consequent effects for marine environments and livelihoods of the fishery‐dependent. Yet there remains a need to better understand how small‐scale fisheries market chains interact with the range of governance institutions that influence them. In this paper, we examine how multiple governance systems function along market chains, in order to identify opportunities for improved multiscale governance. We use three small‐scale fisheries with varying local to global market chains operating in the Asia‐Pacific region to develop a framework for analysis. Drawing from Interactive Governance theory we identify governing systems that have come to operate at particular sections in each market chain. We recognize four institutions that shape the governance over the length of the chain; namely those centred on (a) government, (b) private sector and pricing, (c) decentralized multistakeholder management and (d) culture and social relations. The framework shows how diverse arrangements of these governing institutions emerge and take effect along market chains. In doing so, we seek to move away from prescribed “ideals” of universal governing arrangements for fisheries and their market chains, and instead illuminate how governing systems function interactively across multiple scales.     

延安地区苹果园食心虫种类及其种群消长动态调查

利用5种果树食心虫的性诱剂通过诱捕法调查了延安苹果产区苹果园中桃小食心虫、梨小食心虫、李小食心虫、苹果蠹蛾和桃蛀螟的发生情况及成虫在田间的种群消长动态;对梨小食心虫和李小食心虫性诱剂的“交互引诱”能力进行了测定。结果表明,在苹果园中发生的食心虫主要有桃小食心虫、梨小食心虫和李小食心虫3种,未诱捕到桃蛀螟和苹果蠹蛾。不同调查点的诱捕结果均表明,李小食心虫成虫种群数量最大,属于优势种群,梨小食心虫次之,桃小食心虫种群数量相对最小。桃小食心虫雄成虫1年有2个发生高峰期,越冬代成虫羽化出土极不整齐;梨小食心虫在苹果树整个生长季均可诱捕到,雄成虫1年具有不明显的4个发生盛期;李小食心虫越冬代成虫羽化较为整齐,雄成虫1年有2个明显的发生高峰期,该虫在延安地区年发生2代。梨小食心虫和李小食心虫性诱剂的“交互引诱”试验表明,2种食心虫的性诱剂对种内和种间雄蛾均具有引诱活性,但梨小食心虫性诱剂对种内和种间雄蛾的引诱能力均显著强于李小食心虫性诱剂,诱蛾量分别是李小食心虫性诱剂诱蛾量的2.75和2.30倍,2种食心虫性诱剂的“交互引诱”能力具有不对称性。本试验明确了延安苹果产区食心虫的种类组成及主要食心虫在田间的种群消长规律,对预测预报和治理苹果园食心虫提供了重要的参考依据。     

交互式偏好满意优化在渔船技术经济论证中的应用

针对在玻璃钢渔船技术经济论证中多目标优化的权重设计问题,提出一种交互式偏好权重的遗传算法,使决策者能够在多衡准满意优化中的当前群体中,将对于个体的偏好转换为对于权重数值的偏好关系,利用它们重新构造适应度函数,并作为在Pareto遗传算法的偏好优化方向。通过多次的进化后,决策者能够获取最满意的优化解。该方法避免了传统多目标船型论证中需要事先确定优化目标的权重且才能进行综合评判的缺陷,经玻璃钢渔船经济技术论证的计算实例论证,该方法是可行且有效的。

Engineering Properties and Micro structural Characteristics of Cohesive Soil in the Interactive marine & Terrestrial Deposit

Cohesive soil of the interactive marine & terrestrial deposit along the north side of the Yangtze River estuary has poor physical properties in which water content ratio is approximate or excessive to liquid limit and void ratio is approximate or excessive to one. With free piston thin wall sampling technique and vacuum freeze drying method, undisturbed and remolded samples in different consolidation stress were made. And the micro structural and parameters were analyzed. It was found that the micro structure change and macro mechanic properties were in good agreement. And micro mechanism of the abnormal correspondence was found between the poor physical properties and good mechanic characteristic indexes of structural cohesive soil.     

A decision support tool for response to global change in marine systems: the IMBER‐ADApT Framework

Global change is occurring now, often with consequences far beyond those anticipated. Although there is a wide range of assessment approaches available to address‐specific aspects of global change, there is currently no framework to identify what governance responses have worked and where, what has facilitated change and what preventative options are possible. To respond to this need, we present an integrated assessment framework that builds on knowledge learned from past experience of responses to global change in marine systems, to enable decision‐makers, researchers, managers and local stakeholders to: (i) make decisions efficiently; (ii) triage and improve their responses; and (iii) evaluate where to most effectively allocate resources to reduce vulnerability and enhance resilience of coastal people. This integrated assessment framework, IMBER‐ADApT is intended to enable and enhance decision‐making through the development, a typology of case‐studies providing lessons on how the natural, social and governance systems respond to the challenges of global change. The typology is developed from a database of case‐studies detailing the systems affected by change, responses to change and, critically, an appraisal of these responses, generating knowledge‐based solutions that can be applied to other comparable situations. Fisheries, which suffer from multiple pressures, are the current focus of the proposed framework, but it could be applied to a wide range of global change issues. IMBER‐ADApT has the potential to contribute to timely, cost‐effective policy and governing decision‐making and response. It offers cross‐scale learning to help ameliorate, and eventually prevent, loss of livelihoods, food sources and habitat.
