Site characteristics, and major and trace element composition of sediment cores sampled around the Windmill Islands in 1998

To establish a natural background and its temporal and spatial variability for the area around Casey Station in the Windmill Islands, East Antarctica, the authors studied major and trace element concentrations and the distribution of organic matter in marine and lacustrine sediments. A wide range of natural variability in trace metal concentrations was identified between sites and within a time scale of 9 ka (e.g., Ni 5-37 mg/kg, Cu 20-190 mg/kg, Zn 50-300 mg/kg, Pb 4.5- 34 mg/kg). TOC concentrations are as high as 3 wt.% at the marine sites and 20 wt.% at the lacustrine sites, and indicate highly productive ecosystems. These data provide a background upon which the extent of human impact can be established, and existing data indicate negligible levels of disturbance. Geochemical and lithological data for a lacustrine sediment core from Beall Lake confirm earlier interpretation of recent climatic changes based on diatom distribution, and the onset of deglaciation in the northern part of the Windmill Islands between 8.6 and 8.0 ka BP. The results demonstrate that geochemical and lithological data can not only be used to define natural background values, but also to assess long-term climatic changes of a specific environment. Other sites, however, preserve a completely different sedimentary record. Therefore, inferred climatic record, and differences between sites, can be ascribed to differences in elevation, distance from the shore, water depth, and local catchment features. The extreme level of spatial variability seems to be a feature of Antarctic coastal areas, and demonstrates that results obtained from a specific site cannot be easily generalized to a larger area.

Macroinvertebrate abundance and proportion of trait categories in river biotopes across England and Wales

There is a long tradition of river monitoring using macroinvertebrate communities to assess environmental quality in Europe. A promising alternative is the use of species life-history traits. Both methods, however, have relied on the time-consuming identification of taxa. River biotopes, 1-100 m**2 'habitats' with associated species assemblages, have long been seen as a useful and meaningful way of linking the ecology of macroinvertebrates and river hydro-morphology and can be used to assess hydro-morphological degradation in rivers. Taxonomic differences, however, between different rivers had prevented a general test of this concept until now. The species trait approach may overcome this obstacle across broad geographical areas, using biotopes as the hydro-morphological units which have characteristic species trait assemblages. We collected macroinvertebrate data from 512 discrete patches, comprising 13 river biotopes, from seven rivers in England and Wales. The aim was to test whether river biotopes were better predictors of macroinvertebrate trait profiles than taxonomic composition (genera, families, orders) in rivers, independently of the phylogenetic effects and catchment scale characteristics (i.e. hydrology, geography and land cover). We also tested whether species richness and diversity were better related to biotopes than to rivers. River biotopes explained 40% of the variance in macroinvertebrate trait profiles across the rivers, largely independently of catchment characteristics. There was a strong phylogenetic signature, however. River biotopes were about 50% better at predicting macroinvertebrate trait profiles than taxonomic composition across rivers, no matter which taxonomic resolution was used. River biotopes were better than river identity at explaining the variability in taxonomic richness and diversity (40% and <=10%, respectively). Detailed trait-biotope associations agreed with independent a priori predictions relating trait categories to near river bed flows. Hence, species traits provided a much needed mechanistic understanding and predictive ability across a broad geographical area. We show that integration of the multiple biological trait approach with river biotopes at the interface between ecology and hydro-morphology provides a wealth of new information and potential applications for river science and management.

Occurence of flood laminae in sediments of Ammersee

A 450 year spring-summer flood layer time series at seasonal resolution has been established from the varved sediment record of Lake Ammersee (southern Germany), applying a novel methodological approach. The main results are (1) the attainment of a precise chronology by microscopic varve counting, (2) the identification of detrital layers representing flood-triggered fluxes of catchment material into the lake, and (3) the recognition of the seasonality of these flood layers from their microstratigraphic position within a varve. Tracing flood layers in a proximal and a distal core and correlating them by application of the precise chronology provided information on the depositional processes. Comparing the seasonal flood layer record with daily runoff data of the inflowing River Ammer for the period from 1926 to 1999 allowed the definition of an approximate threshold in flood magnitude above which the formation of flood layers becomes very likely. Moreover, it was possible for the first time to estimate the "completeness" of the flood layer time series and to recognize that mainly floods in spring and summer, representing the main flood seasons in this region, are well preserved in the sediment archive. Their frequency distribution over the entire 450 year time series is not stationary but reveals maxima for colder periods of the Little Ice Age when solar activity was reduced. The observed spring-summer flood layer frequency further shows trends similar to those of the occurrence of flood-prone weather regimes since A.D. 1881, probably suggesting a causal link between solar variability and changes in midlatitude atmospheric circulation patterns.

Neogene floras and palaeoclimatic estimates from various sites of South-West China

Neogene climates and vegetation history of western Yunnan are reconstructed on the basis of known fossil plants using the Coexistence Approach (CA) and Leaf Margin Analysis (LMA). Four Neogene leaf floras from Tengchong, Jianchuan and Eryuan in southwestern China are analyzed by the CA, and the paleoclimatic data of one Miocene carpoflora from Longling and three Pliocene palynofloras from Longling, Yangyi and Eryuan are used for comparison. The Miocene vegetation of the whole of West Yunnan is subtropical evergreen broad-leaved forest, and a similar mean annual precipitation is inferred for Tengchong, Longling and Jianchuan. However, by the Late Pliocene a large difference in vegetation occurred between the two slopes of Gaoligong Mountain, western Yunnan. The region of Tengchong retained a subtropical evergreen broad-leaved forest vegetation, whereas in Yangyi and Eryuan a vertical vegetation zonation had developed, which consists, in ascending order, of humid evergreen broad-leaved, needle and broad-leaved mixed evergreen, and coniferous forests. Distinctively, the Late Pliocene vegetational patterns of West Yunnan were already very similar to those of the present, and the Pliocene mean annual precipitation in Tengchong was markedly higher than that of Yangyi and Eryuan. Considering that the overall vegetation of West Yunnan and the precipitation at Yangyi and Eryuan have undergone no distinct change since the Late Pliocene, we conclude that the Hengduan Mountains on the northern boundary of West Yunnan must have arisen after the Miocene and approached their highest elevation before the Late Pliocene. Furthermore, the fact of the eastern portion of the Tibetan Plateau underwent a slight uplift after the Late Pliocene is also supported.

On the monitoring of surface displacement in connection with volcano reactivation in Tenerife, Canary Islands, using space techniques

Geodetic volcano monitoring in Tenerife has mainly focused on the Las Cañadas Caldera, where a geodetic micronetwork and a levelling profile are located. A sensitivity test of this geodetic network showed that it should be extended to cover the whole island for volcano monitoring purposes. Furthermore, InSAR allowed detecting two unexpected movements that were beyond the scope of the traditional geodetic network. These two facts prompted us to design and observe a GPS network covering the whole of Tenerife that was monitored in August 2000. The results obtained were accurate to one centimetre, and confirm one of the deformations, although they were not definitive enough to confirm the second one. Furthermore, new cases of possible subsidence have been detected in areas where InSAR could not be used to measure deformation due to low coherence. A first modelling attempt has been made using a very simple model and its results seem to indicate that the deformation observed and the groundwater level variation in the island may be related. Future observations will be necessary for further validation and to study the time evolution of the displacements, carry out interpretation work using different types of data (gravity, gases, etc) and develop models that represent the island more closely. The results obtained are important because they might affect the geodetic volcano monitoring on the island, which will only be really useful if it is capable of distinguishing between displacements that might be linked to volcanic activity and those produced by other causes. One important result in this work is that a new geodetic monitoring system based on two complementary techniques, InSAR and GPS, has been set up on Tenerife island. This the first time that the whole surface of any of the volcanic Canary Islands has been covered with a single network for this purpose. This research has displayed the need for further similar studies in the Canary Islands, at least on the islands which pose a greater risk of volcanic reactivation, such as Lanzarote and La Palma, where InSAR techniques have been used already.

Mary, Quite Contrary: The Novels of Mary Davys, 1700-1727

As a relatively unknown author, Mary Davys (1674-1732) has garnered scant scholarly attention and little admiration for her work. Those who have written on Davys’s prose fiction most often mention the last three texts she published, Familiar Letters betwixt a Gentleman and a Lady (1716), The Reform’d Coquet (1724), and The Accomplish’d Rake (1727), yet rare mention is made of her first three novels. Moreover, of her later novels, many scholars read them as socially conservative and as representations of Davys’s support of and belief in patriarchy. My project disproves the long-standing and generally agreed upon conceptions regarding Davys’s writings and demonstrates the significance of her life’s work to studies of the novel. By investigating contemporary cultural issues, discussing the popular genres and modes of early eighteenth-century England, and comparing and contrasting Davys’s fiction to other authors’, I explore the myriad ways in which Davys experimented with the formal properties of the novel. Also, by closely examining each novel independently, I foreground Davys’s willingness to engage with charged contemporary topics such as rape, suicide, the laws surrounding inheritance, and male privilege. Not only does she engage with these topics; there is a discernable voice of protest imbedded in the narratives. At times, the techniques Davys employed and the plots she created in her work obscured her social concerns, yet with close reading, subversion also surfaces as one of Davys’s methods. An analysis of Davys’s experimentations with prose fiction and form illuminates the ways in which those innovations allowed Davys to criticize the culture in which she lived. Furthermore, an investigation of the whole of Davys’s work and the totality of her novels—looking at both form and content—exemplifies the importance of Davys for students of feminist thought and the development of the novel.

The migration of Ukrainians in times of crisis. OSW COMMENTARY Number 187, 2015-10-19

Before the Russian annexation of Crimea and the outbreak of the conflict in eastern Ukraine, the scale of labour outward migration of Ukrainians had been characterised by a slight downward trend. Back in 2014, an increase in the number of Ukrainians who migrated to Russia was observed, although no similar increase was recorded for EU countries (excluding Poland). The year 2015 brought a more rapid surge in the number of Ukrainians migrating to the EU, again mainly to Poland. Due to the lack of current EU-wide data, estimates can be made based only on data compiled by national statistical offices in countries which are the most popular with Ukrainian migrants. In Poland, as of October 2015 Ukrainians held 52,000 valid residence cards. Much greater migration dynamics have been observed in the case of temporary migration – the number of declarations which enable an individual to take up a temporary job in Poland, issued in the first half of 2015, was a staggering 400,000. This means a more than twofold increase – in the whole of 2014 372,000 declarations were issued to Ukrainian citizens. No similar increase has so far been observed in other EU states, including Italy and the Czech Republic, which have always been popular destinations for Ukrainian migration. In late 2014, 233,000 Ukrainian migrants were registered in Italy (in late 2013 the figure was 191,000), whereas in the Czech Republic the number of Ukrainian migrants remains stable – 104,000 in June 2015.

Hostages to dialogue. The process of normalising Serbian-Kosovar relations. OSW COMMENTARY No. 214, 2016-06-08

In March 2011, the governments of Kosovo and Serbia started a dialogue that was intended to lead to the normalisation of mutual relations. This process, launched under the pressure of the EU, was aimed at building up confidence between the parties and resolving the everyday problems of the Serbian and Albanian communities, and as a consequence, reducing tension in the Western Balkans. The start of talks between representatives of the antagonist countries was the breakthrough that led to the Kosovo government gaining control over the whole of its territory, the establishment of a border (or ‘administrative boundary line’, as Belgrade calls it), and the start of the process of subordinating the Kosovo Serbian institutions to the authorities in Prishtina. Serbia also lifted its trade blockade on Kosovo, and allowed Prishtina to join the regional organisations. As a result, progress has been made in the process of integration of both states with the EU: Serbia has started accession negotiations, and Kosovo has signed a Stabilisation and Association Agreement (SAA).

Stable isotop record of sediments across MIS 5 and Termination II

New surface water records from two high sedimentation rate sites, located in the western subtropical North Atlantic near the axis of the Gulf Stream, provide clear evidence of suborbital climate variations through marine isotope stage (MIS) 5 persisting even into the warm peak of the interglaciation (substage 5e). We found that the amplitude of suborbital climate oscillations did not vary significantly for the whole of MIS 5, implying that ice volume has little or no influence on the amplitude of suborbital climate variability in this region. Although some records suggest that longer suborbital variations (4-10 kyr) during MIS 5 are linked to deepwater changes, none of the existing records is of sufficient resolution to assess if a linkage occurred for oscillations shorter than 4 kyr. However, when examined in conjunction with published data from the Norwegian Sea, new evidence from the subpolar North Atlantic suggests that coupled surface-deepwater oscillations occurred during the penultimate deglaciation. This supports the hypothesis that during glacial and deglacial times, ocean-ice interactions and deepwater variability amplify suborbital climate change at higher latitudes. We suggest that during the penultimate deglaciation the North Atlantic deepwater source varied between Nordic Sea and open North Atlantic locations, in parallel with surface temperature oscillations.
