Historically, America's use and enjoyment of the oyster extend far back into prehistoric times. The Native Americans often utilized oysters, more intensively in some areas than in others, and, at least in some areas of the Caribbean and Pacific coast, the invading Spanish sought oysters as eagerly as they did gold-but for the pearls. That was the pearl oyster, Pinctada sp., and signs of its local overexploitation were recorded early in the 16th century. During the 1800's, use of the eastern oyster grew phenomenally and, for a time, it outranked beef as a source of protein in some parts of the nation. Social events grew up around it, as it became an important aspect of culture and myth. Eventually, research on the oyster began to blossom, and scientific literature on the various species likewise bloomed-to the extent that when the late Paul Galtsoff wrote his classic treatise "The American oyster Crassostrea virginica Gmelin" in 1954, he reported compiling an extensive bibliography of over 6,000 subject and author cards on oysters and related subjects which he deposited in the library of the Woods Hole Laboratory of the Bureau of Commercial Fisheries (now NMFS). That large report, volume 64 (480 pages) of the agency's Fishery Bulletin, was a bargain at $2.75, and it has been a standard reference ever since. But the research and the attendant literature have grown greatly since Galtsoff's work was published, and now that has been thoroughly updated.

This is the Mersey Estuary baseline survey: Analysis of macroinfaunal samples, literature review and database production report produced by the Environment Agency North West in 2002. This report presents an ecological review of the Mersey estuary along with an extensive bibliography of the available environmental literature for this system. The central objective of this programme has been to provide the information necessary to support the Environment Agency's review of existing and future consents (for discharges, abstractions etc) in the Mersey estuary. This review of consents was required because the Mersey had been designated as a Special Protection Area (SPA) under the EC Birds Directive. Therefore under Regulation 50 of the Conservation, the Environment Agency was responsible for reviewing any extant consent, or future applications, which may directly or indirectly, affected this SPA.

O objetivo da presente dissertação consiste em analisar o sublime, um conceito estético que vem sendo estudado desde os primeiros séculos. Tomamos como base a definição do sublime como algo paradoxal que cria o prazer e o medo ao mesmo tempo. Porém, o sublime apresenta especificidades que variam de acordo com o filósofo analisado. Neste trabalho, três críticos foram estudados: Longinus, Edmund Burke e Immanuel Kant. Assim, o sublime pode ser representado através da imensidão da natureza, do poder de uma criatura sobrenatural ou, até mesmo, através da sexualidade feminina. E, com o intuito de exemplificar essas diferentes perspectivas do sublime, buscamos obras da Literatura Gótica. Sendo esta uma vertente literária que buscava a oposição ao racionalismo trazido pelo movimento iluminista, as características sublimes foram essenciais para enfatizar a emoção. Para tal exemplificação, utilizamos trechos de dois romances góticos dos séculos XVIII e XIX, respectivamente: The Monk escrito por Matthew Lewis e Dracula escrito por Bram Stoker

Through research aimed at understanding the coastal environment, surveys designed to help manage the resource, and national programs to monitor environmental condition, we see a picture of a dynamic ecosystem that is Cape Romain National Wildlife Refuge (CRNWR). Currently, there are efforts underway to protect threatened species; monitor fish populations; and quantify the biological, physical, and chemical characteristics of this environment. The potential impacts to this system are just now being understood as ecological responses to human modification are observed and explained. As a starting point, this document compiles existing information about Cape Romain NWR in five topic areas and addresses the potential impacts to the Refuge. This review is intended to serve as a stepping stone to developing a research agenda in support of management of the Refuge. There are various sources of information on which to build a framework for monitoring conditions and detecting change to this environment. For instance, information on basic ecological function in estuarine environments has evolved over several decades. Long-term surveys of Southeast fisheries exist, as well as shellfish and sediment contaminants data from estuaries. Environmental monitoring and biological surveys at the Refuge continue. Recently, studies that examine the impacts to similar coastal habitats have been undertaken. This document puts past studies and ongoing work in context for Refuge managers and researchers. This report recommends that the next phase of this resource characterization focus on: • compiling relevant tabular and spatial data, as identified here, into a Geographic Information System (GIS) framework • assessing the abundance and diversity of fisheries utilizing CRNWR • delineating additional data layers, such as intertidal habitats and subtidal clam beds, from low-level aerial photography, hard copy maps, and other sources • continued inventories of plant and animal species dependent on the Refuge • monitoring physical and chemical environmental parameters using the methodology employed at National Estuarine Research Reserve System (NERRS) and other coastal sites, where appropriate • further definition of the potential risks to the Refuge and preparing responses to likely impacts.

大车前(Plantago major L. "Giant Turkish.")不仅有很高的药用价值,在生态学研究方面也是重要模式植物。大车前的组织培养工作,目前报道很少。对其组织培养体系的建立,为筛选大车前耐盐突变体和基因转化建立高效的体外再生系统和实验平台体系。通过愈伤组织诱导和直接不定芽再生途径, 建立了大车前(Plantago major L. "Giant Turkish.")的快速高效再生系统。叶片外植体在含有1.0 mg/L NAA的MS培养基中培养3周后,形成愈伤组织,愈伤组织在含4.0 mg/L 6-BA的MS培养基中成功再生,得到完整植株。种子外植体在含0.2 mg/L IAA和1.0 mg/L TDZ的MS培养基中培养4周后产生大量的丛生芽,对9株再生植株进行RAPD检测表明,部分植株在DNA水平上发生了变异。 植物抵御盐胁迫的一个重要机制是在液泡中积累Na+,从而使细胞质内Na+保持在较低水平,并且降低细胞渗透势。Na+运输到液泡是由液泡Na+/H+逆向转运蛋白完成的。本实验室已从盐生植物盐角草(Salicornia europaea)和番杏(Tetragonia tetragonioides)中分别克隆得到SeNHX1和TtNHX1基因。本文研究了SeNHX1和TtNHX1基因在酵母突变体里的作用。TtNHX1和SeNHX1蛋白在缺陷型酵母菌株里的表达能够提高这些菌株对NaCl、LiCl和潮霉素的抗性,提高到与野生型相当的抗性水平。说明TtNHX1和SeNHX1有着与酵母ScNHX1相似的细胞定位和作用机制,是ScNHX1的功能类似蛋白。
