黄骅全新世古黄河三角洲的特点及演化研究

通过对黄骅地区的实地调查，根据钻孔的分析对比，对黄骅地区全新世以来古黄河三角洲的特点、分布及其演化有了更进一步的认识。从沉积物的矿物成分，粒度变化、垂向结构等方面与现代黄河三角洲对比研究，证明黄骅地区全新世以来确实存在古黄河三角洲，其各方面特征与现代黄河三角洲相近或相同。只是因多期迭覆，后期改造，使之成为一个不十完整的、复杂的古黄河三角洲的复合体。

Abstract. The sponge fauna of three neighbouring submarine caves of the Island of Majorca (Balcaric Islands) is studied along a light gradient; 45 species have been recorded and systematic data are given for those showing morphological, pigmentary, or spicule differences. Adaptation to darkness and precarious trophic conditions is also discussed.     

珠江三角洲及河网形成演变的数值模拟和地貌动力学分析:距今6000~2500a

珠江三角洲是我国一个极其复杂的大尺度河口系统,具有独特的河网体系和河口湾.为了探讨距今6 000 a以来珠江三角洲和河网的形成演变,提出一个长周期动力形态模型(PRD-LTMM)并讨论长周期模拟方法的建模和验证思想,重建了距今6 000 a海进盛期的古珠江河口湾的水下地形作为模型的初始边界.在模型中考虑的驱动力和控制因素包括代表潮、河流流量、泥沙输入、海平面变化、沉积物压实率及新构造运动等.分析和计算了三角洲总沉积量、有效堆积空间和沉积速率,用于模型控制和校验.应用必要的模型约减技术,实际模拟了长周期模型.34个14C测年钻孔资料初步验证了模型的正确性,一些古文化遗迹证据可以印证模拟结果.地貌动力学分析进一步论证了计算结果的合理性,阐述了模型输出的地学意义.现阶段的研究揭示出海进盛期以来珠江三角洲的时空演进过程具有一些与已有研究成果大不相同的新的特征.提出距今6 000 a以来珠江三角洲等沉积时间线和若干沉积模式.珠江三角洲发育演变及其特征在很大程度上源自其继承性的地质地貌构造所造成的独特的古海湾构造形态及其对河流和海洋动力分布的重塑.珠江河口的“门”及其双向射流动力体系对珠江三角洲和河网主干,特别对口门的形成演变起了控制性的作用,模拟结果还表明,古珠江河口湾中散落的众多基岩岛丘边沿沉积是影响珠江三角洲长期演变的重要因素.     

对虾白斑综合症病毒核衣壳蛋白VP664的鉴定研究

对虾白斑综合症病毒核衣壳蛋白VP664是至今知道的分子量最大的结构蛋白，全长18234bp，预计编码6077个氨基酸．从编码vp664基因的两端各选600bp，分别命名为vp664n、vp664c进行原核表达，成功表达纯化了目的蛋白并制备抗体．蛋白印记杂交（Western blot）实验中蛋白特异抗体只与完整的病毒和核衣壳裂解蛋白中的VP664蛋白反应，而不和膜蛋白反应，证明VP664基因所编码的蛋白在完整病毒颗粒上定位于核衣壳．

Geographic and bathymetric trends in abundance, biomass and body size of four grenadier fishes along the Iberian coast in the western Mediterranean

The present study is a mesoscale analysis of latitude and depth related trends in abundance, biomass and body size of the four grenadier species Caelorinchus caelorhincus, Hymenocephalus italicus, Nezumia aequalis and Trachyrinchus scabrus inhabiting the deep western Mediterranean. We have analysed data from seven annual bottom trawl surveys, carried out down to 800 m depth along the Iberian Mediterranean coast covering a distance of approximately 1200 km. The objectives were to establish general patterns in the mesoscale distribution of abundance, biomass and body size of deep-water grenadier fishes and also analyse the consistency of the bathymetric distribution of these parameters along a large latitudinal gradient. Five complementary series of analyses have been completed. The first focussed on describing the general patterns of abundance and size by correspondence canonical analysis, CCA, in the area. The second and third series focussed on the existence of temporal, geographical and bathymetric trends of abundance, weight and mean size by analysis of covariance, ANCOVA and multiple regression analysis. The fourth series compared the frequency distributions of body length. Finally, the last series focussed on the patterns of abundance versus size. The total number of individuals of all four grenadier species captured in 260 bottom trawls amounted to 27,435 and their weight was 1404 kg. No general trends for the four species have been observed between years. All four species showed a general pattern of increasing size with depth, which, except in the case of C. caelorhincus, was consistent along a large latitudinal gradient. Nezumia aequalis was unique in showing the same noticeable trend of increasing abundance with depth along the entire latitudinal range, but with clear differences in the intercepts. The abundance of N. aequalis and C. caelorhincus decreased significantly northwards. Hymenocephalus italicus was the least abundant species and had a homogeneous distribution without any specific trend along the entire latitudinal range analysed. The distribution of T. scabrus in the Mediterranean seemed to be more localised. Higher abundances were found to the north and south of the latitudinal gradient with lower values between. The grenadiers studied also showed a general trend of decreasing mean size northwards, except in the case of the smallest species, H. italicus. The relation between abundance and body size differed between sectors for the whole grenadier population and species-specific variations were also observed. The relationship between individual body mass and population density fit well to a second-order polynomial function rather than to a linear regression, showing a significant trend for density to increase with increasing size until some mid-point, then to decline with increasing size thereafter. The observed latitudinal gradient in the distribution patterns of grenadiers along the upper slope of the western Mediterranean can be discussed in relation to direct and indirect factors of biogeographic, environmental and anthropogenic origin.     

Contractual solution to the tragedy of property right in coastal fisheries

This article aims to analyze how private property regimes can co-exist with common property regimes in a coastal area. The case study shows how the dynamics of private property and common property right holders is in creating commitment to make symbiosis in resource use. This is based on a case study in two villages in West Lombok, Indonesia, where pearl-culture as a private property resource exists in a common property regime. This is a successful story in dealing with the tragedy of property rights in the country wherein established institutional arrangement is still absent. Nevertheless, this may be site specific, and fragile if there is no institutional arrangement combining formal and informal rules and involving both formal and informal authorities. To make a robust solution, multilevel solution must be considered: national, local, and community level, with reference to Japan case.
