Ag‐rich Tetrahedrite in the El Zancudo Deposit, Colombia: Occurrence, Chemical Compositions and Genetic Temperatures
Authors: Gallego Hernández Alba Nury , Akasaka Masahide 
Published: September 2010

AbstractChemical compositions of tetrahedrite—Ag‐rich tetrahedrite—freibergite solid solutions (Ag‐rich tetrahedritess) and homogenization temperatures of fluid inclusions in quartz and carbonates of seventeen samples from nine veins in the El Zancudo deposit, Antioquia, Colombia, were investigated to reveal the origin of silver in Ag‐rich tetrahedritess, to derive their crystallization temperatures and to examine the relationship between chemical compositions of Ag‐rich tetrahedritess and their crystallization temperatures. The ores consist of arsenopyrite, pyrite, sphalerite, Ag‐rich tetrahedritess, galena, boulangerite, andorite, owyheeite, diaphorite, jamesonite, miargyrite, bournonite, chalcopyrite, and electrum. Ag‐rich tetrahedritess forms about 10 volume % of the total ores and is one of the most common and widely distributed sulfosalts in this deposit. Ag‐rich tetrahedritess is rich in Ag (1.13 to 31.02 wt%) and Sb (22.93 to 29.82 wt%), and poor in As (0.06 to 2.43 wt%), consistent with the reported incompatibilities of Ag and As in Ag‐rich tetrahedritess. The Zn/(Zn + Fe)‐, Ag/(Ag + Cu)‐ and Sb/(Sb + As + Bi)‐atomic ratios exhibit some variations among the veins. Ag‐rich tetrahedritess with higher Ag/(Ag + Cu) ratios coexist with diaphorite, whereas those with lower ratios are not associated with this sulfosalt. Ag‐rich tetrahedritess in the assemblages of Ag‐rich tetrahedritess+ sphalerite and of Ag‐rich tetrahedritess+ bournonite + galena shows no Zn ↔ Fe and Cu ↔ Ag variations between core and rim, respectively, negating the possibility of solid state reaction during cooling. Ag‐rich tetrahedritess is thus regarded as primary phase. Homogenization temperatures of primary fluid inclusions in quartz and carbonates co‐existing with Ag‐rich tetrahedritess define the mineralization temperatures of 134 to 263°C. Independent crystallization temperatures of Ag‐rich tetrahedrite estimated based on Zn/(Zn + Fe) and Ag/(Ag + Cu) ratios of the Ag‐rich tetrahedritess associated with silver minerals such as miargyrite, andorite and diaphorite using Sack's thermochemical database lie in a range between 170 and ∼250°C. Both results are thus in good agreement.
Molybdenite Re‐Os and Zircon SHRIMP U‐Pb Dating at the Baishiding Deposit, Guposhan District: New Evidence for Silurian Mo Mineralization in South China
Authors: Li Xiaofeng , Feng Zuohai , Wang Cunzheng , Li Rongshen , Tang Zhuanhong 
Published: September 2010

AbstractThe Baishiding molybdenum deposit is located in the Central‐Middle Guangxi depression zone of the South China Caledonian fold zone. Orebodies occur as quartz‐molybdenite veins within the Guiling monzonite pluton and arkosic quartz sandstone of Zhengyuanling Group in the northeastern Guangxi. They are NEE‐trending with a dip angle of 75–80°. Zircon SHRIMP U‐Pb geochronologic analyses of the Guiling monzonite show age of 424.4 ± 5.6 Ma. It indicates that the Guiling monzonite was emplaced in Silurian. The ore minerals in quartz‐molybdenite veins contain molybdenite, pyrite, chalcopyrite and scheelite. Six molybdenite samples yield Re‐Os ages between 433.3 ± 6.3 Ma and 417.2 ± 5.7 Ma, with a weighted mean age of 424.6 ± 5.7 Ma, which agrees with the zircon age of the Guiling monzonite pluton. It suggests that the deposit was formed in the Silurian, not the Jurassic as previously thought. The Baishiding deposit is the only Silurian molybdenum deposit so far recognized in the South China. It was probably formed in a crustal shortening setting along the continental margin in the Silurian.

Hirsch, Robert M., Douglas L. Moyer, and Stacey A. Archfield, 2010. Weighted Regressions on Time, Discharge, and Season (WRTDS), With an Application to Chesapeake Bay River Inputs. Journal of the American Water Resources Association (JAWRA) 46(5):857‐880. DOI: 10.1111/j.1752‐1688.2010.00482.xAbstract:  A new approach to the analysis of long‐term surface water‐quality data is proposed and implemented. The goal of this approach is to increase the amount of information that is extracted from the types of rich water‐quality datasets that now exist. The method is formulated to allow for maximum flexibility in representations of the long‐term trend, seasonal components, and discharge‐related components of the behavior of the water‐quality variable of interest. It is designed to provide internally consistent estimates of the actual history of concentrations and fluxes as well as histories that eliminate the influence of year‐to‐year variations in streamflow. The method employs the use of weighted regressions of concentrations on time, discharge, and season. Finally, the method is designed to be useful as a diagnostic tool regarding the kinds of changes that are taking place in the watershed related to point sources, groundwater sources, and surface‐water nonpoint sources. The method is applied to datasets for the nine large tributaries of Chesapeake Bay from 1978 to 2008. The results show a wide range of patterns of change in total phosphorus and in dissolved nitrate plus nitrite. These results should prove useful in further examination of the causes of changes, or lack of changes, and may help inform decisions about future actions to reduce nutrient enrichment in the Chesapeake Bay and its watershed.
Alien fish and crayfish species in Hellenic freshwaters and aquaculture
Authors: Perdikaris Costas , Gouva Evangelia , Paschos Ioannis 
Published: September 2010

AbstractThe diversity of ichthyofauna in Hellenic freshwaters is highlighted by the presence of 161 species. This actually represents 27.8% of the total fish species recorded in European freshwater, including both native and introduced species, suggesting that Greece represents a ‘hot spot’ for biodiversity. The introduction of alien species for restocking, the aquarium trade and aquaculture was responsible for the deliberate or accidental release of alien specimens into open waters and in some cases for establishing populations. In contrast, commercially valuable alien species (e.g. salmonids, cyprinids and more recently sturgeons) generated significant income to individuals, companies and to the national economy. This paper aims to review the situation regarding the presence of alien fish and crayfish species in Hellenic freshwaters and in particular in aquaculture and to flesh out issues concerning their aquaculture potential.
Monitoring, assessment and management of fish farm environments in Japan
Authors: Yokoyama Hisashi 
Published: September 2010

AbstractIn Japan, coastal fish farming has become a well‐established industry. Intensive cultivation of finfish, however, generates large amounts of organic waste and nutrients, resulting in environmental deterioration in and around aquaculture facilities. Such negative effects have become increasingly conspicuous since the commencement of fish farming in the mid 1960s and its subsequent rapid development during the 1970s and 1980s. Various studies have attempted to measure the material fluxes in fish farms, to assess the potential environmental impacts, to determine criteria for the optimization of the location of farms and production levels, and to establish methods for improvement of aquaculture environments. In this review, research conducted during the last five decades in Japan concerning the flux of feed, environmental impacts of fish farming, factors controlling the degree of impacts, the upper limit of production and methods for improvement of environments is reviewed and current concerns for aquaculture environments discussed.

Published: September 2010

Abstract:Late Middle Triassic to early Late Triassic insects from Argentina have been previously described from the Bermejo and Cuyana Basins where they have been recovered from the Ischichuca‐Los Rastros and Potrerillos‐Cacheuta Formations, respectively. The insect fauna discussed herein was collected during field studies in 1986/1987 from the Llantenes section (Norian to Rhaetian? Late Triassic), which is situated in the Malargüe Basin in southern Mendoza province. The insect remains were found in the upper part of the Llantenes section (Llantenes Formation), which is built up of two coarsening‐upwards cycles reflecting a deltaic progradation of a fluvial into a lacustrine environment (lower part), succeeded by repeated progradations into a floodplain‐dominated environment (upper part; with finds of insects, conchostracans, fish remains, plant fragments, and drifted logs). The new finds represent the youngest Triassic insect records described from Argentina and even from South America in its entirety. There is only one contemporaneous fossil assemblage in Gondwana: in the Clarence/Moreton Basin (Aberdare Conglomerate; Late Norian) in Australia. The new Triassic insects include an impression of an isolated Mecopterida‐like wing (Mendozachorista volkheimeri gen. et sp. nov.; Mendozachoristidae fam. nov.), coleopteran elytra of the Permosynidae (Ademosyne rosenfeldi sp. nov. and Ademosyne llantenesensis sp. nov.) and other isolated body fragments. This new Late Triassic entomofauna from Argentina is of considerable importance in the reconstruction of the biotic recovery of continental environments in Gondwana after the catastrophic mass extinction at the P/T boundary.

A New Mantispid‐Like Species of Rhachiberothinae (Neuroptera: Berothidae) from Baltic Amber, with a Critical Review of the Fossil Record of the Subfamily
Authors: MAKARKIN Vladiir N. , KUPRYJANOWICZ Janusz 
Published: September 2010

Abstract: Whalfera wiszniewskii sp. nov. is described from the Late Eocene Baltic amber. The genus Whalfera is considered as the only fossil genus confidently assigned to the Rhachiberothinae. Others previously placed in this subfamily belong to Paraberothinae (except perhaps for Oisea). The Late Eocene/present Rhachiberothinae and the Cretaceous Paraberothinae are considered to be the subfamilies of Berothidae.
New Mesozoic Mesopsychidae (Mecoptera) from Northeastern China
Authors: Dong REN , LABANDEIRA Conrad C. , ChungKun SHIH 
Published: September 2010

Abstract:The Mesozoic family Mesopsychidae Tillyard, 1917 presently consists of seven described genera and 13 species from the mid‐Triassic to the Early Cretaceous of Australia, South Africa and Eurasia. In the present paper one new genus and three new species of fossil mesopsychids are described that add significant distributional and stratigraphic extensions to the family. This finding documents the first formal record of fossil Mesopsychidae in China. Both Lichnomesopsyche gloriae gen. et sp. nov. and L. daohugouensis gen. et sp. nov. were found from the Middle Jurassic Jiulongshan Formation of Inner Mongolia, whereas Vitimopsyche kozlovi sp. nov., of mid Early Cretaceous age, was collected from the Jehol Biota of northern Hebei Province. This new, well‐preserved material from China reveals complete and previously unknown body features, including head, antennae, mouthparts, legs and abdomen. The delicate and long proboscides of these new taxa indicate that they were feeding on externally exposed, nutrient‐rich fluids of gymnospermous ovulate fructifications, and incapable of piercing surface epidermis – attributable principally to the absence of stylets. These proboscides originated, perhaps multiply, among basal Mecoptera and are functionally and structurally convergent with equivalent mouthparts borne by fossil and extant Diptera, Lepidoptera, Neuroptera and Coleoptera.

Plant‐Arthropod Associations from the Lower Miocene of the Most Basin in Northern Bohemia (Czech Republic): A Preliminary Report
Authors: PROKOP Jakub , WAPPLER Torsten , KNOR Stanislav , KVAČEK Zlatko 
Published: September 2010

Abstract:Terrestrial plants and insects currently account for the majority of the Earth's biodiversity, and approximately half of insect species are herbivores. Thus, insects and plants share ancient associations that date back more than 400 Myr. However, investigations of their past interactions are at the preliminary stages in Western Europe. Herein, we present the first results of our study of various feeding damage based on a dataset of nearly 3500 examined plant specimens from the Lower Miocene of the Lagerstätte Bílina Mine in the Most Basin, Czech Republic. This site provides a unique view of the Neogene freshwater ecosystems. It has long been studied by scientists working in different branches of sedimentology, paleobotany, and paleozoology. The fossils are preserved in three characteristic horizons overlaying the coal seam (Clayey Superseam Horizon, Delta Sandy Horizon, and Lake Clayey Horizon), reflecting paleoenvironmental changes in a short time period of development. The trace fossils are classified as functional feeding groups or “guilds”, without searching for a direct cause or a recent analog host relation. Approximately 23% of specimens of dicotyledonous plant leaves were found to be damaged and associated with some leaf “morphotypes”. Deciduous plant‐host taxa, and those with a chartaceous texture typical of riparian habitats, were frequently damaged, such asPopulus, recorded with two speciesPopulus zaddachiiandPopulus populina(57.9% and 31% herbivory levels, respectively), followed byAcer, Alnus, andCarya, averaging almost 30% of damaged leaves/leaflets. There has been evidence of 60 damage types (DT) representing all functional feeding groups recorded at the Bílina Mine, including 12 types of leaf mines and 16 gall‐type DT. In total, Lower Miocene of the Lagerstätte Bílina Mine exhibits a high level of external foliage feeding types (23.7%), and a low level of more specialized DT, such as galls (4.3%) and leaf mines (<1%). A broader comparison based on DT of the main sedimentary environments shows significance supporting different biomes by frequency of damage levels and DT diversities.

Middle Jurassic Coptoclavidae (Insecta: Coleoptera: Dytiscoidea) from China: a Good Example of Mosaic Evolution
Authors: Bo WANG , PONOMARENKO A. G. , Haichun ZHANG 
Published: September 2010

Abstract:Adults of the aquatic coptoclavid beetles (Coleoptera: Adephaga: Dytiscoidea), described from four Middle Jurassic fossil localities in Inner Mongolia and Liaoning in northeastern China, are attributed toDaohugounectes primitivesWang, Ponomarenko and Zhang, 2009, which was previously proposed after study of larvae. The generic nameTimarchopsisBrauer, Redtenbacher and Ganglbauer, 1889 is proposed as a substitute for the preoccupied and junior homonymNecronectesPonomarenko, 1977, non Milne‐Edwards, 1881. Furthermore, the subfamily name Necronectinae Ponomarenko, 1977 is substituted by the available name Timarchopsinae.Daohugounectesis placed into Timarchopsinae because its adults have long, slightly apically widened tibiae and small femoral plates. The adults of this genus differ from those of other Timarchopsinae in the following features: antennae short and widened in the middle part; basal segments of protarsi not cut apically; metaventrite with a triangular plate. The larvae look like somewhat primitive forms in the subfamily Timarchopsinae. In contrast to these primitive larvae, the adults with some advanced characters can be regarded as among the most advanced forms in the subfamily Timarchopsinae, and probably represent a transition between the Timarchopsinae and Charanoscaphinae. Such mosaic evolution withinDaohugounectesindicates that the evolutionary process of aquatic beetles is far more complex than previously thought.
A New Species of the Family Juraperlidae (Insecta: Grylloblattida) from the Middle Jurassic of China
Authors: Yingying CUI , BÉTHOUX Olivier , Chungkun SHIH , Dong REN 
Published: September 2010

Abstract: Juraperla grandis sp. nov. (Grylloblattida: Juraperlidae) is described from the Daohugou locality (Middle Jurassic, China). Its wing venation is very similar to that of Juraperla daohugouensis Huang and Nel, 2007 (Grylloblattida: Juraperlidae), in the particular occurrence of a supplementary longitudinal vein in the area between the anterior wing margin and ScP. The larger size of the new specimen, the lower number of CuAl branches, and the occurrence of two rows of cells between MP and CuA in forewings justify the erection of a new species, J. grandis sp. nov.. The material also preserved hind wing and body structures, described for the first time in Juraperlidae.
THE NATURAL CYBORG: THE STAKES OF BERGSON'S PHILOSOPHY OF EVOLUTION
Authors: Marrati Paola 
Published: September 2010

abstractBergson's engagement with evolutionary theory was remarkably up to date with the science of his time. One century later, the scientific and social landscape is undoubtedly quite different, but some of his insights remain of critical importance for the present. This paper aims at discussing three related aspects of Bergson's philosophy of evolution and their relevance for contemporary debates: first, the stark distinction between the affirmation of the reality of change and becoming, on the one hand, and any notion of progress on the other; second, the insistence on the intimate interplay between forms of knowledge and forms of life; third, his idea that machines and organisms, technology and biology, are not separate domains but, rather, stem from and answer to the same problems and needs that living beings express. Such a Bergsonian framework may prove very helpful in reassessing the implicit assumptions of several contemporary debates on the ethical and political stakes of evolution, biosciences, and technologies, as well as the increasingly problematic boundary between “biology” and “culture.”
DARWIN'S INVISIBLE HAND: FEMINISM, REPROGENETICS, AND FOUCAULT'S ANALYSIS OF NEOLIBERALISM
Authors: McWhorter Ladelle 
Published: September 2010

abstractIn his 1979 lecture series now translated as The Birth of Biopolitics, Michel Foucault suggests that there is an important relationship between neoliberalism and the cluster of phenomena he had previously named “biopower.” The relationship between these two apparently very different forms of governmentality is not obvious, however, and Foucault does not explicate it. The question has become a pressing one for feminists because it underlies a set of issues surrounding the emerging field of “reprogenetics.” Feminists have been highly critical of invasive reproductive technologies for decades, viewing them as demeaning to and dangerous for women's bodies and as staunchly traditional in their reinforcement of gender roles and of maternity as female desire and destiny. Reprogeneticists accuse feminists of hypocrisy in seeking to curtail the widest technically possible range of “procreative choice.” This essay traces some ways in which reprogenetics may be interpreted as a biopolitical formation as well as a neoliberal formation and suggests how the two seemingly antithetical types of phenomena might actually be overlapping and mutually reinforcing—perhaps opening the way for a more effective feminist critique.
CREATIVE EVOLUTION AND THE CREATION OF MAN
Authors: Colebrook Claire 
Published: September 2010

abstractThis paper argues that Darwin's theory of evolution offers (at least) two modes of understanding the relation between life and human knowledge. On the one hand, Darwin can be included within a general turn to “life,” in which human self‐knowledge is part of a general unfolding of increasing awareness and anthropological reflexivity; life creates an organism, man, capable of discerning the logic of organic existence. On the other hand, Darwin offers the possibility of understanding life beyond the self‐maintenance of organism and, therefore, beyond the rational of life's putative striving.
SUPPLEMENTING CLAIRE COLEBROOK: A RESPONSE TO “CREATIVE EVOLUTION AND THE CREATION OF MAN”
Authors: Anderson Nicole 
Published: September 2010

abstractIn her paper “Creative Evolution and the Creation of Man,” one of the arguments Colebrook puts forth is that as a means of challenging the mechanistic and teleological conception of Darwinian evolution, creative evolution takes an antihumanist position by positing that there is an absence of end, thus “man” is able to create his own end. But in taking this position, Colebrook points out that creative evolution re‐establishes the humanistic discourse on the human that it was attempting to challenge. To elucidate Colebrook's argument, this paper draws on the work of Derrida to “play” with the notion of style in order to reflect on the ways in which philosophical deductive argumentation and reasoning constitute and perpetuate humanist and metaphysical discourses on the human, and the ends of “man.”
