Observations of increasing water color and organic carbon concentrations in lakes are widespread across the Northern Hemisphere. The drivers of these trends are debated. Declining atmospheric sulfur deposition has been put forward as an important underlying factor, since recovery from acidification enhances mobility of organic matter from surrounding soils. This would suggest that the current brow

Understanding what controls the lateral flux of organic and inorganic carbon from landscapes to surfacewaters is key to fully understanding terrestrial ecosystem carbon balances, the biogeochemistry of fresh-waters, and how the hydrologically-mediated movement of carbon between these ecosystems may be alteredby global change. In this paper, we synthesize current knowledge and identify major knowled

The article reflects on the mechanisms aimed to control the fulfillment of the EU sustainability criteria for biofuels, as they were promoted in Directive 2009/28/EC. The article contains the final results of the research initiated in the work Pavlovskaia, E. (2013) “Controlling the Fulfillment of the EU Sustainability Criteria for Transport Biofuels”, which was published in RELP 4/2013. The artic

Multiple mechanisms contribute to tissue demise and functional recovery after stroke. We studied the involvement of macrophage migration inhibitory factor (MIF) in cell death and development of neurologic deficits after experimental stroke. Macrophage migration inhibitory factor is upregulated in the brain after cerebral ischemia, and disruption of the Mif gene in mice leads to a smaller infarct v

Regional cerebral blood flow was measured by the 133-xenon inhalation method during resting in 38 healthy men and 38 healthy women matched pairwise for age in the range 18-72 years. The results showed 11% higher global flow level in the women in all ages. A similar and significant regression of flow by age was seen for both sexes. The regional flow distribution also showed some sex-related differe

BackgroundPostzygotic isolation in the form of reduced viability and/or fertility of hybrids may help maintain species boundaries in the face of interspecific gene flow. Past hybridization events between house sparrows (Passer domesticus) and Spanish sparrows (P. hispaniolensis) have given rise to a homoploid hybrid species, the Italian sparrow (P. italiae). Although genetic incompatibilities are

Biomass residues are often considered key in a reorientation towards circular bioeconomies, both by returning organic matter and nutrients to soils and by expanding the feedstock base for fossil-free products. Different indicators are available to assess progress towards circularity, but many available indicators and assessments seem to focus on product or material circularity, and lack in coverag

A long-standing question in evolutionary biology is how historical biogeographic processes have shaped the current diversity of organisms, especially for highly diverse groups. We study the diversification dynamics and biogeographic processes of one of the most diverse families of Lepidoptera, Geometridae, with over 24,000 described species and a worldwide distribution. Despite the cosmopolitan di

Anthropogenic biodiversity decline threatens the functioning of ecosystems and the many benefits they provide to humanity 1. As well as causing species losses in directly affected locations, human influence might also reduce biodiversity in relatively unmodified vegetation if far-reaching anthropogenic effects trigger local extinctions and hinder recolonization. Here we show that local plant dive

Introduction. We aimed to investigate effects of soil pH and phosphate availability on bryophyte species in unshaded dry–mesic habitats, and to explore their implications for bioindication and conservation.Methods. Species abundance, pH and water-soluble phosphate data were collected from 1098 relevés in southernmost Sweden. Soil variable effects on 95 bryophyte taxa and species richness were eval
