Population cycles have long fascinated ecologists from the time of Charles Elton in the 1920s. The discovery of large population fluctuations in undisturbed ecosystems challenged the idea that pristine nature was in a state of balance. The 10-year cycle of snowshoe hares (Lepus americanus Erxleben) across the boreal forests of Canada and Alaska is a classic cycle, recognized by fur traders for more than 300 years. Since the 1930s ecologists have investigated the mechanisms that might cause these cycles. Proposed causal mechanisms have varied from sunspots to food supplies, parasites, diseases, predation, and social behaviour...

Though a number of reports on the use of electroconvulsive therapy (ECT) has been published from the Central-Eastern European region over the past two decades, a systematic review of this literature has not been published. Thus the aim of this paper was to review recent trends in ECT practice in Central-Eastern Europe. Systematic literature search was undertaken using the Medline, PSYCHINFO and EMBASE databases covering the period between January 2000 and December 2013. Relevant publications were found from the following countries: Bulgaria, Croatia, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, Serbia, Slovakia, Ukraine, but none from Albania and Moldova...

Recent evidence supports the association between healthy dietary patterns and a reduced risk of depression. The objective was: (1) to examine the associations between dietary patterns and alexithymic features; and (2) investigate whether these possible associations are explained by depressive symptoms in a cross-sectional study among the Finnish general population aged 25-65 years. The study population was a part of the population-based Kuopio Depression Study (KUDEP) conducted in central-eastern Finland (n = 1747)...

REVIEW
Susie Vrobel
This paper focusses on the notions of time and timelessness in Eastern and Western thought traditions. The Introduction addresses the Eastern differentiation between the mind, which does not operate in a successive manner and is therefore not caught in time, and the time-laden successively operating mind and brain. I also describe how Jiddu Krishnamurti reconciles the two through insight, an event which restructures the brain and culminates in an eternal Now. In the following sections, I draw analogies to Western notions of timelessness and insight...

Increased organic carbon and nitrogen accumulation rates (OCAR and ONAR) in lake sediment significantly regulate the global carbon cycle. However, the reasons for and contributors to the increased OCAR and ONAR are unclear. Seven sediment cores, collected in July 2014 from Dianchi Lake, China, were used to evaluate the effects of autochthonous and allochthonous sources on OCAR and ONAR. The results indicate that OCAR and ONAR increased by factors of 4.33 and 7.34 over the past hundred years (1900-2000), particularly after algal blooms began to occur frequently (beginning in the 1980s)...

Pseudogymnoascus destructans, the fungus that causes white-nose syndrome in hibernating bats, has spread across eastern North America over the past decade and decimated bat populations. The saprotrophic growth of P. destructans may help to perpetuate the white-nose syndrome epidemic, and recent model predictions suggest that sufficiently reducing the environmental growth of P. destructans could help mitigate or prevent white-nose syndrome-associated bat colony collapse. In this study, we screened 301 microbes from diverse environmental samples for their ability to inhibit the growth of P...

Kenneth F Kellner, Robert K Swihart
Early tree life history and demography are driven by interactions with the environment such as seed predation, herbivory, light availability, and drought. For oak (Quercus) in the eastern United States, these interactions may contribute to oak regeneration failure. Numerous studies have examined the impact of individual factors (like seed predation) on the oak regeneration process, but less information is available on the relative and combined impacts of multiple intrinsic and extrinsic factors on early oak life history...

Rapid improvement of tick-borne encephalitis after treatment with corticosteroids Tick-borne encephalitis (TBE) is a viral disease transmitted by ticks. The virus is divided into three subtypes named Western, Siberian and Far Eastern TBE virus (TBEV). Western TBEV is endemic in parts of Europe and Sweden and typically causes a biphasic illness with influenza-like symptoms followed by neurological symptoms ranging from mild meningitis to severe meningoencephalitis and death. Despite an effective vaccine, TBE is increasing in Sweden and Europe...
