Disturbances are believed to be one of the main factors influencing variations in community diversity and functioning. Here we investigated if exposure to a pH press disturbance affected the composition and functional performance of a bacterial community and its resistance, recovery and resilience to a second press disturbance (salt addition). Lake bacterial assemblages were initially exposed to r
The migration of the great snipe Gallinago media was previously poorly known. Three tracks in 2010 suggested a remarkable migratory behaviour including long and fast overland non-stop flights. Here we present the migration pattern of Swedish male great snipes, based on 19 individuals tracked by light-level geolocators in four different years. About half of the birds made stopover(s) in northern Eu
Movement and migration are fundamental parts of the life cycle of most organisms on Earth and occur at an astonishing range of spatial and temporal scales, from iconic pole-to-pole migrations of some birds to diel migrations of enormous amounts of millimeter-sized crustaceans through the waters of oceans and lakes. To move or not to move in a certain situation is a decision that is often taken by
OBJECTIVES: To determine whether CA 125 measurement is superior to ultrasound imaging performed by an experienced examiner for discriminating between benign and malignant adnexal lesions, and to determine whether adding CA 125 to ultrasound examination improves diagnostic performance. METHODS: This is a prospective multicenter study (International Ovarian Tumor Analysis (IOTA) study) conducted in
This is the third annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedish
This is the fifth annual report of the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010.

the body of literature on institutional fragmentation and interlinkages has become quite extensive over the last 10-15 years, especially in global environmental governance research. This common ground and the merits of existing scholarly approaches notwithstanding, there are still major new conceptual, theoretical and empirical grounds to be explored. Conceptually, the literature could further go
Prostate-specific antigen (PSA) is a glycoprotein produced by the prostate gland. It occurs in several molecular forms in the blood and assays have been developed to measure free PSA and PSA in complex with alpha-1-antichymotrypsin (PSA-ACT). Higher proportions of free PSA (PSA-F/T) in blood are found in subjects with benign prostatic hyperplasia (BPH) as compared to cancer patients. Utilizing imm
REDD is one of the latest additions to a series of incentive-based mechanisms for reducing carbon emissions. Although international negotiations have not eliminated uncertainties regarding its social, economic and political implications, many developing and emerging countries have begun to engage in REDD. Peru, the country with the world’s fourth largest tropical forest area has good reason to par
The global governance architecture on climate change has been increasingly marked by institutional fragmentation. A growing diversity of institutions seeks to address dangerous climate change today, including international organizations, club-like forums, multi-stakeholder partnerships, regulated and voluntary markets, sub-national efforts and non-state actor initiatives. After taking stock of thi
Mass-flowering crops provide forage for bees but also contain pesticides. Such pesticide exposure can harm bees, but our understanding of how this cost is balanced by forage benefits is limited. To provide insights into benefits and costs, we placed bumblebee colonies in 18 landscapes with conventional red clover fields treated with the neonicotinoid thiacloprid (flowers + pesticide), untreated or
BACKGROUND: Triticum aestivum (wheat) is one of the world's oldest crops and has been used for >8000 years as a food crop in North Africa, West Asia and Europe. Today, wheat is one of the most important sources of grain for humans, and is cultivated on greater areas of land than any other crop. As the human population increases and soil salinity becomes more prevalent, there is increased pressure
Agricultural production systems are affected by complex interactions between social and ecological factors, which are often hard to integrate in a common analytical framework. We evaluated differences in crop production among farms by integrating components of several related research disciplines in a single socio-ecological analysis. Specifically, we evaluated spring barley (Hordeum vulgare, L.)
We report here on a peptide hydrogel system, which in contrast to most other such systems, is made up of relatively short fibrillar aggregates, discussing resemblance with colloidal rods. The synthetic model peptides A8K and A10K, where A denotes alanine and K lysine, self-assemble in aqueous solutions into ribbon-like aggregates having an average length 〈L〉 on the order of 100 nm and with a diame
