Bacteria and fungi are the two principal decomposer groups in soils, determining rates of biogeochemical cycling. Rewetting of dry soils induces enormous dynamics in biogeochemistry. Bacteria have been shown to exhibit large variation in growth over time upon drying-rewetting (D/RW), however, in studies to date, fungal growth has shown limited responsiveness. Here we investigated whether fungal gr

Butterfly monitoring schemes are recording programs initiated to monitor nationwide butterfly abundance and distribution patterns, often with help from volunteers. The method generates high-resolution data, but may be associated with a degree of habitat sampling bias if volunteers prefer to survey areas perceived to be high-quality butterfly habitats. This can result in habitats becoming underrepr

The phylogenetic relationships among hemosporidian parasites, including the origin of Plasmodium falciparum, the most virulent malaria parasite of humans, have been heavily debated for decades. Studies based on multiple-gene sequences have helped settle many of these controversial phylogenetic issues. However, denser taxon sampling and genome-wide analyses are needed to confidently resolve the evo

Oxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C. The stoichiometry of the reaction has been determined: [Tl(H2O)6]3++ SO2(aq)+ 2H2O →[Tl(H2O)6]++ HSO4–+ 3H+. The kinetics has been studied by use of stopped-flow spectrophotometry under pseudo-first-order conditions with eOxidation of dissolved sulfur dioxide, SO2·nH2O, HSO3– and SO32–, by hexaaquathallium(III) has been studied in acidic aqueous solution with ionic strength 1.0 mol dm–3 at 25 °C.

Climate change will alter precipitation patterns with consequences for soil C cycling. An understanding of how fluctuating soil moisture affects microbial processes is therefore critical to predict responses to future global change. We investigated how long-term experimental field drought influences microbial tolerance to lower moisture levels (“resistance”) and ability to recover when rewetted af

The combination of coagulation/flocculation and discfiltration with ozonation to reduce nutrients and organic micro-pollutants in secondary effluent was studied in pilot scale at Lundåkraverket wastewater treatment plant in Landskrona, Sweden. With a chemical dose of 4 gAl3þ/m3 and 1.5 g/m3 cationic polymer as active material effluent water quality with regards to total phosphorous (Tot-P), suspenThe combination of coagulation/flocculation and discfiltration with ozonation to reduce nutrients and organic micro-pollutants in secondary effluent was studied in pilot scale at Lundåkraverket wastewater treatment plant in Landskrona, Sweden.

The study uses household level data from four villages inand around Cross River National Park (CRNP), Nigeria to assess therole of primate meat in local livelihoods and diets. Okwangwo is anenclave community within the national park, Butatong houses theCRNP headquarters. Kanyang1 and Abo Ebam are located fartheraway from the park. 149 respondents were surveyed.

Different ways of viewing human-nature interactions affect the ways in which these are conceptualized and operationalized with regards to cultural ecosystem services (CES). To clarify if some conceptualizations provide more appropriate descriptions of benefits, these need to be discussed in relation to the lived experience. This paper addresses some aspects of the controversy around the use of the

In 2019, the Climaginaries project ran a climate fiction competition. Out of more than 40 entries, five winners were selected and published in this collection. More of the entries can be found on climaginaries.org/anthroposcenes.

Ecosystem services that people depend upon for their well-being are being lost at an alarming rate. These services include the provisioning of natural resources, food, medicine, flood protection, climate regulation, water purification, and biodiversity retention. In the U.S., the main threat to these services comes from the rapid pace of land conversion. In just a twenty- year period, an area the
