A ship run aground Deepening problems in the Ukrainian economy. OSW Commentary Number 173, 16 June 2015

The drop in Ukraine’s GDP by nearly 18% in the first three months of 2015 (versus the corresponding period in 2014) has confirmed the decline of the country’s economy. Over the last 14 months, the Ukrainian currency was subject to an almost threefold devaluation against the US dollar, and in April 2015 the inflation rate was 61% (year-on-year), which exacerbated the impoverishment of the general public and weakened domestic demand. The main reason behind the crisis has been the destruction of heavy industry and infrastructure in the war-torn Donbas region, over which Kyiv no longer has control, as well as a sharp decline in foreign trade (by 24% in 2014 and by 34% in the first quarter of 2015), recorded primarily in trading volume with Ukraine’s major trade partner, i.e. Russia (a drop of 43%). The conflict has also had a negative impact on the production figures for the two key sectors of the Ukrainian economy: agriculture and metallurgy, which account for approximately 50% of Ukrainian exports. The government’s response to the crisis has primarily been a reduction in the costs of financing the Donbas and an increase in the financial burden placed on the citizens and companies of Ukraine. No radical reforms which would encompass the entire system, including anti-corruption reforms, have been carried out to stop the embezzlement of state funds and to facilitate business activity. The reasons for not initiating reforms have included the lack of will to launch them, Ukraine’s traditionally slow pace of bureaucratic action and growing dissonance among the parties making up the parliamentary coalition. The few positive changes, including marketisation of energy prices and sustaining budgetary discipline (in the first quarter of 2015, budgetary revenues grew by 25%, though partly as a result of currency devaluation), are being carried out under pressure from the International Monetary Fund, which is making the payment of further loan instalments to the tune of US$ 17.5 billion conditional upon reforms. Despite assistance granted by Western institutional donors and by individual states, the risk of Ukraine going bankrupt remains real. The issue of restructuring foreign debt worth US$ 15 billion has not been resolved, as foreign creditors who hold Ukrainian bonds have not consented to any partial cancellation of the debt. Whether Ukraine’s public finances can be stabilised will depend mainly on the situation in the east of the country and on the possible renewal of military action. It seems that the only way to rescue Ukraine’s public finances from deteriorating further is to continue to ‘freeze’ the conflict, to gradually implement wide-ranging reforms and to reach a consensus in negotiations with lenders.

Ukraine’s wartime nationalism. OSW COMMENTARY NUMBER 179, 28.08.2015

From the Introduction. The Euromaidan revolution and the war in Donbas that followed it have brought about deep changes in the way Ukrainian citizens think and have led to a rapid transformation of how people view the concept of national community. It began to be increasingly common for proponents of nationalism to refer to solidarity with the state instead of referring to the nation understood as an ethnic community, as they had previously done. This is due to the fact that an entire young generation has matured which takes the Ukrainian state for granted, but also because in the Russian-Ukrainian conflict most Russian-speaking citizens of Ukraine have opted for Ukraine.

‘The oil friendship’: the state of and prospects for Russian-Chinese energy cooperation. OSW Commentary NUMBER 197|17.02.2016

The oil sector has been the major element of Russian-Chinese energy cooperation. The years 2013–2015 saw a significant increase in the volume of crude oil exported by Russia. In 2015, China became the main importer of Russian oil; Russia became the second largest supplier of oil to the Chinese market, after Saudi Arabia. From Beijing’s perspective, supplies of Russian oil are of strategic importance because the main supply routes are overland routes. Russia, for its part, is interested in boosting its export because of its deteriorating position on the European market, which hitherto has been considered a strategic market.

Macedonia: a superficial democracy in the shadow of crises. OSW COMMENTARY NUMBER 206/31.03.2016

Until 2008, Macedonia was leading the process of EU and NATO integration, and (after Croatia) was the fastest-reforming Western Balkan country. However, since Macedonia’s negotiations on joining the EU and NATO were blocked, in connection with its dispute with Greece, the Macedonian government has moved away from a policy of reform towards reinforcing its autocratic system and consolidating society behind nationalist slogans. Also the EU, which had hitherto been the driving force behind the changes, has due to its internal crises been paying little attention to violations of democratic standards in the Republic of Macedonia, tensions in relations between the Slavic Macedonians and the Albanian minority (which make up over 25% of the population), and the country’s permanent political domestic crises.

Assessment of fight outcome is needed to activate socially driven transcriptional changes in the zebrafish brain

Group living animals must be able to express different behavior profiles depending on their social status. Therefore, the same genotype may translate into different behavioral phenotypes through socially driven differential gene expression. However, how social information is translated into a neurogenomic response and what are the specific cues in a social interaction that signal a change in social status are questions that have remained unanswered. Here, we show for the first time, to our knowledge, that the switch between status-specific neurogenomic states relies on the assessment of fight outcome rather than just on self- or opponent-only assessment of fighting ability. For this purpose, we manipulated the perception of fight outcome in male zebrafish and measured its impact on the brain transcriptome using a zebrafish whole genome gene chip. Males fought either a real opponent, and a winner and a loser were identified, or their own image on a mirror, in which case, despite expressing aggressive behavior, males did not experience either a victory or a defeat. Massive changes in the brain transcriptome were observed in real opponent fighters, with losers displaying both a higher number of differentially expressed genes and of coexpressed gene modules than winners. In contrast, mirror fighters expressed a neurogenomic state similar to that of noninteracting fish. The genes that responded to fight outcome included immediate early genes and genes involved in neuroplasticity and epigenetic modifications. These results indicate that, even in cognitively simple organisms such as zebrafish, neurogenomic responses underlying changes in social status rely on mutual assessment of fighting ability.

Long-term Responses of Mountain Ecosystems to Environmental Changes: Resilience, Adjustment, and Vulnerability

The steep environmental gradients of mountain ecosystems over short distances reflect large gradients of several climatic parameters and hence provide excellent possibilities for ecological research on the effects of environmental change. To gain a better understanding of the dynamics of abiotic and biotic parameters of mountain ecosystems, long-term records are required since permanent plots in mountain regions cover in the best case about 50 - 70 years. In order to extend investigations of ecological dynamics beyond these temporal limitations of permanent plots, paleoecological approaches can be used if the sampling resolution can be adapted to ecological research questions, e.g. a sample every 10 years. Paleoecological studies in mountain ecosystems can provide new ecological insights through the combination of different spatial and temporal scales. [f we thus improve our understanding of processes across both steep environmental gradients and different time scales, we may be able to better estimate ecosystem responses to current and future environmental change (Ammann et al. 1993; Lotter et al. 1997). The complexity of ecological interactions in mountain regions forces us to concentrate on a number of sub-systems - without losing sight of the wider context. Here, we summarize a few case studies on the effects of Holocene climate change and disturbance on the vegetation of the Western Alps. To categorize the main response modes of vegetation to climatic change and disturbance in the Alps we use three classes of ecological behaviour: "resilience", "adjustment", and "vulnerability", We assume a resilient (or elastic) behaviour if vegetation is able to recover to its former state, regaining important ecosystem characteristics, such as floristic composition, biodiversity, species abundances, and biomass (e.g. Küttel 1990; Aber and Melillo 199 1). Conversely, vegetation displacements may occur in response to climatic change and/or disturbance. In some cases, this may culminate in irreversible large-scale processes such as species and/or community extinctions. Such drastic developments indicate high ecosystem vulnerability (or inelasticity or instability, for detailed definitions see Küttel 1990; Aber and Melillo 199 1) to climatic change and/or disturbance. In this sense, the "vulnerability" (or instability) of an ecosystem is expressed by the degree of failure to recover to the original state before disturbance and/or climatic change. Between these two extremes (resilience vs. vulnerability), ecosystem adjustments to climatic change and/or disturbance may occur, including the appearance of new and/or the disappearance of old species. The term "adjustment" is hence used to indicate the response of vegetational communities, which adapted to new environmental conditions without losing their main character. For forest ecosystems, we assume vegetational adjustments (rather than vulnerability) if the dominant (or co-dominant) tree species are not outnumbered or replaced by formerly unimportant plant species or new invaders. Adaptation as a genetic process is not discussed here and will require additional pbylogeographical studies (that incorporate the analysis of ancient DNA) in order to fully understand the distributions of ecotypes.

Being young in a changing world: how temperature and salinity changes interactively modify the performance of larval stages of the barnacle Amphibalanus improvisus

The fate of key species, such as the barnacle Amphibalanus improvisus, in the course of global change is of particular interest since any change in their abundance and/or performance may entail community-wide effects. In the fluctuating Western Baltic, species typically experience a broad range of environmental conditions, which may preselect them to better cope with climate change. In this study, we examined the sensitivity of two crucial ontogenetic phases (naupliar, cypris) of the barnacle toward a range of temperature (12, 20, and 28°C) and salinity (5, 15, and 30 psu) combinations. Under all salinity treatments, nauplii developed faster at intermediate and high temperatures. Cyprid metamorphosis success, in contrast, was interactively impacted by temperature and salinity. Survival of nauplii decreased with increasing salinity under all temperature treatments. Highest settlement rates occurred at the intermediate temperature and salinity combination, i.e., 20°C and 15 psu. Settlement success of "naive" cyprids, i.e., when nauplii were raised in the absence of stress (20°C/15 psu), was less impacted by stressful temperature/salinity combinations than that of cyprids with a stress history. Here, settlement success was highest at 30 psu particularly at low and high temperatures. Surprisingly, larval survival was not highest under the conditions typical for the Kiel Fjord at the season of peak settlement (20°C/15 psu). The proportion of nauplii that ultimately transformed to attached juveniles was, however, highest under these "home" conditions. Overall, only particularly stressful combinations of temperature and salinity substantially reduced larval performance and development. Given more time for adaptation, the relatively smooth climate shifts predicted will probably not dramatically affect this species.

Volume changes of Jacobshavn Isbrae between 1985, 1997 and 2007

Following three decades of relative stability, Jakobshavn Isbrae, West Greenland, underwent dramatic thinning, retreat and speed-up starting in 1998. To assess the amount of ice loss, we analyzed 1985 aerial photos and derived a 40 m grid digital elevation model (DEM). We also obtained a 2007 40 m grid SPOT DEM covering the same region. Comparison of the two DEMs over an area of ~4000 km**2 revealed a total ice loss of 160 ± 4 km**3, with 107 ± 0.2 km**3 in grounded regions (0.27 mm eustatic sea-level rise) and 53 ± 4 km**3 from the disintegration of the floating tongue. Comparison of the DEMs with 1997 NASA Airborne Topographic Mapper data indicates that this ice loss essentially occurred after 1997, with +0.7 ± 5.6 km**3 between 1985 and 1997 and -160 ± 7 km**3 between 1997 and 2007. The latter is equivalent to an average specific mass balance of -3.7 ± 0.2 m/a over the study area. Previously reported thickening of the main glacier during the early 1990s was accompanied by similar-magnitude thinning outside the areas of fast flow, indicating that the land-based ice continued reacting to longer-term climate forcing.

Force training induces changes in human muscle membrane properties.

INTRODUCTION Human muscle membrane properties can be assessed in vivo by recording muscle velocity recovery cycles (MVRCs). This study was undertaken to study the effect of muscle force training on MVRC parameters. METHODS MVRCs with 1 to 5 conditioning stimuli were recorded from brachioradialis muscle before and after 2 weeks of muscle force training in 12 healthy subjects. The effects of training on relative refractory period and early and late supernormality were quantified. RESULTS Force training induced a reduction of relative refractory period (P < 0.0001), while early supernormality was increased (P < 0.02) and peaked earlier (P < 0.01). Late supernormality and the increases in late supernormality due to 2 and 5 conditioning stimuli remained unchanged. CONCLUSIONS Muscle force training leads to hyperpolarization of the resting muscle membrane potential, probably caused by an increase in the number of sodium pump sites.
