The aim of the present study was to investigate the combined effects of seasonality and anthropogenic pressure on a battery of oxidative stress, lipid peroxidation, protein oxidation, DNA damage and histological alterations in the native clam Ruditapes decussatus collected from a less contaminated area (LCA), Ghar El Melh, a moderately contaminated area (MCA), the North Lake, and a highly contaminated area (HCA), the South Lake, all located in the southern Mediterranean Sea. The accumulation of cadmium, lead, copper, iron and zinc was higher in the digestive glandsof clams collected from the MCA and the HCAthan in those from the LCA, particularly during the warm season. Our results reveal that metallothionein, lipid peroxidation, protein oxidation levels and antioxidant defence systems were higher, while acetylcholinesterase activity was lower, in clams from the MCAand HCAthan in those from the LCA. The results also indicate that clams from the MCA and the HCAare characterized by histological alterations and DNA damage. In conclusion, the evident changes of antioxidant defence systems and macromolecules between the studied lagoons reveal the perturbation of the physiological states of clams from polluted sites thatcope with seasonal changes and trace element accumulations.
本研究的目的是研究季节性和人为压力对从污染较少地区（LCA）、Ghar El Melh、中度污染地区（MCA）、北湖、，以及一个高度污染区南湖，全部位于地中海南部。MCA和HCAthan采集的蛤蜊消化腺中镉、铅、铜、铁和锌的积累高于LCA采集的蛤蚌，尤其是在温暖季节。我们的结果表明，MCA和HCAthan的蛤蜊中金属硫蛋白、脂质过氧化、蛋白质氧化水平和抗氧化防御系统较高，而乙酰胆碱酯酶活性较低。结果还表明，MCA和HCAa的蛤蜊具有组织学改变和DNA损伤的特征。总之，所研究的泻湖之间抗氧化防御系统和大分子的明显变化揭示了污染地区蛤蜊的生理状态对季节变化和微量元素积累的扰动。

Understanding phenotypic plasticity of species at different spatial scales is vital in the current context of an increasing pace of environmental changes. Through this knowledge, it is possible to predict their potential to adapt and/or evolve in face of new environmental conditions such as climate change, and/or to understand their ecological range expansion. In Patagonian rocky salt-marshes, one of the most abundant invertebrate species is the scorched mussel Perumytilus purpuratus. In this system, this mussel can be found inhabiting both vegetated and non-vegetated patches, which differ in critical environmental conditions. We performed a field study evaluating whether mussels growing in vegetated patches differ in shell shape from those growing in adjacent non-vegetated patches. We sampled individuals from both patch types and assessed their shell shape and size using geometric morphometrics. The results showed that mussels from vegetated patches had shells that were more dorsoventrally expanded, anterodorsally restricted and globose in shape than those from non-vegetated patches, which showed the opposite traits resulting in a more elongated shell. The differences found could be driven by the different conditions of temperature, desiccation rate, wave action and population density to which mussels are exposed in each patch type. These results revealed the striking phenotypic plasticity of shell form of this native species at a fine-grained scale, which could be one of the explanations for its success in its ecological range expansion.

Phylogenetic hypotheses for the peracarid order Cumacea are scarce and have not provided a solution to the full extent. In the present study, a fragment of the mitochondrial 16S rDNA was used to erect a phylogenetic hypothesis for three cumacean families, Diastylidae, Bodotriidae and Leuconidae, along with intra-family relationships of the latter. The Cumacea resolved monophyletic with tanaids and isopods as outgroup taxa. The Diastylidae were the only family with good support for monophyly. The genus Leucon resolved paraphyletic, whereas the subgenus Crymoleucon was monophyletic. Furthermore, the genetic structure was analysed for two leuconid species, Leucon antarcticus Zimmer, 1907 and L. intermedius Mühlenhardt-Siegel, 1996, from the Weddell Sea and the Ross Sea. The two species showed different patterns of intraspecific genetic variability. In contrast to L. intermedius, a bimodal distribution of pairwise genetic distances was observed for L. antarcticus, which is correlated with geographical and depth distributions between the Ross Sea and the Weddell Sea. Although a clear evaluation of cryptic speciation in these species requires additional work on more specimens from more geographic regions and broader depth ranges, differences shown in the sequences of 16S rDNA can only be explained by genetic separation of populations between the Weddell Sea and the Ross Sea for an extended period of time.
过硬目Cumacea的系统发育假说很少，也没有提供一个完整的解决方案。本研究利用线粒体16S rDNA片段，建立了三个cumacean科(Diastylidae, Bodotriidae和Leuconidae)的系统发育假说，以及后者的家族内关系。Cumacea是单系的，以单足类和等足类为外群。唯一具有较好单系性支持的科是双翅亚科。Leucon属分解为单系，而Crymoleucon亚属分解为单系。此外，我们还分析了威德尔海和罗斯海的两个白鱼种Leucon antarcticus Zimmer(1907)和L. intermedius m hlenhardt- siegel(1996)的遗传结构。这两个物种表现出不同的种内遗传变异模式。与中间乳杆菌相反，南极乳杆菌的双遗传距离呈双峰分布，与罗斯海和威德尔海之间的地理和深度分布有关。虽然对这些物种的隐种形成进行明确的评估需要对更多地理区域和更广泛深度范围的更多标本进行额外的工作，但16S rDNA序列所显示的差异只能用威德尔海和罗斯海之间长时间种群的遗传分离来解释。

Ramon Margalef López (1919-2004) was one of the most prominent scientists of the 20th century in the fields of limnology, oceanography and ecology. His contributions to theoretical ecology, which won him international recognition, were based on a great deal of laboratory and field work and on extensive observations of the natural world, a passion that he acquired at a young age. Some of the early papers of Ramon Margalef appeared in the Publicaciones del Instituto de Biología Aplicada, but as of 1955 many of his marine studies were published in Investigación Pesquera, the journal of the Instituto de Investigaciones Pesqueras of the CSIC in Barcelona. He also wrote several articles for Scientia Marina, the journal that replaced Investigación Pesquera in 1989 after the Instituto de Investigaciones Pesqueras became the Institut de Ciències del Mar. The present article aims to give an overview of Margalef’s contributions to these journals to mark the celebration in 2019 of the 100th anniversary of his birth.
Ramon Margalef López（1919-2004）是20世纪湖沼学、海洋学和生态学领域最杰出的科学家之一。他对理论生态学的贡献为他赢得了国际认可，这是基于大量的实验室和实地工作，以及对自然世界的广泛观察，这是他从小就获得的热情。Ramon Margalef的一些早期论文发表在Aplicada生物研究所的出版物上，但截至1955年，他的许多海洋研究都发表在巴塞罗那CSIC Pesqueras研究所的期刊Investigación Pesquera上。他还为《科学码头》杂志写了几篇文章，该杂志于1989年取代了《科学研究》杂志，当时《科学研究所》成为了《科学》杂志。本文旨在概述Margalef对这些期刊的贡献，以纪念2019年Margalef诞辰100周年。
