Climate change calls for adaptive strategies to manage land system across governance levels, as differing multi-level policies distinctly shape land system and long-term ecosystem resilience. This study proposes an iterative approach for optimizing land-use pathways that balance competing policy objectives across national, provincial, and local levels without compromising ecosystem integrity in a
The Swedish Tundra Northwest Expedition of 1999 visited 17 sites throughout the Canadian Arctic. At 12 sites that were intensively sampled we estimated the standing crop of plants and the densities of herbivores and predators with an array of trapping, visual surveys, and faecal-pellet transects. We developed a trophic-balance model using ECOPATH to integrate these observations and determine the f
Markstörningar, som stubbskörd och markberedning, leder initialt till minskad koldioxidavgång från marken, visar en serie nya försök. Det är tvärtemot vad man tidigare har antagit. Efter det första året ligger avgången på ungefär samma nivå för störd mark som för ostörd.
A three stacked power amplifier implemented in 28nm fully depleted silicon-on-insulator complementary metal oxide semi-conductor technology (FDSOI CMOS) is presented. It has a differential architecture with on-chip input and output transformer baluns. The PA achieves a saturated output power level of 17.9dBm with a peak power added efficiency of 7% and an output referred gain compression point of

Wildfires are a natural disturbance shaping boreal forests, but their effects on soil microbial communities and biogeochemical cycling remain unclear, particularly in Fennoscandia. We investigated the impact of fire severity and post-fire management on the soil microbial community two years after a boreal wildfire in Sweden. We quantified growth rates of bacteria, saprotrophic fungi (SF), ectomyco
Canopy decline is increasingly prevalent in high-elevation snow gum (Eucalyptus pauciflora) forests across the Australian Alps. This phenomenon, known as snow gum dieback, is associated with infestations by the wood-boring beetle, Phoracantha mastersi. The larvae of this beetle create feeding galleries in the tree trunk, leading to the exudation of kino, a tannin-rich resin produced as a defense r
Året är 2053 och den svenska regeringen har just invigt museet FOSSIL och dess första utställning ’Carbon Ruins’. År 2045 uppnådde Sverige nettonollutsläpp av växthusgaser, och blev därmed det första landet i världen att lämna den fossila tidsåldern (1849 - 2049). Två hundra år som förde med sig en otrolig välståndsökning, men också oljerelaterade konflikter och en klimatkatastrof som allvarligt hIt is 2053. The Swedish government has just opened its landmark museum FOSSIL with its first exhibition Carbon Ruins. The exhibition and its grand opening is a celebration of the fact that global net-zero emissions of carbon dioxide were reached in 2050. Sweden, in line with its 2017 targets, reached net-zero emissions of greenhouse gases already in 2045, being the first country in the world to st
Nitrogen (N) and phosphorus (P) limitation constrains the magnitude of terrestrial carbon uptake in response to elevated carbon dioxide and climate change. However, global maps of nutrient limitation are still lacking. Here we examined global N and P limitation using the ratio of site-averaged leaf N and P resorption efficiencies of the dominant species across 171 sites. We evaluated our predictio
Methods currently used for inventory control in industry are with few exceptions developed more than forty years ago. This is for instance the case with methods like reorder point sys-tems, cover-time planning and material requirements planning (MRP). Lead times at that time were typically several weeks and months and order quantities covered typically de-mand over several months. Since then both
Much of today’s public discourse on crime cases take place on online platforms, as long chains of high-speed posts: speculations, analyses, and laments, as well as ironic, sarcastic, and derogatory comments. These give excellent (and yet risky) possibilities to engage in homemade investigation, with other posters as instant reviewers and audiences. In this article, we explore the interactional oriMuch of today’s public discourse on crime cases take place on online platforms, as long chains of high-speed posts: speculations, analyses, and laments, as well as ironic, sarcastic, and derogatory comments.

Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produc
Forskning och nya metoder för skogsbruk visar att svensk skog kan binda mycket mer koldioxid än i dag och samtidigt ge virke med högre värden. Vi menar att svensk skog är underutnyttjad, skriver flera debattörer.
Forests are invaluable terrestrial ecosystems with considerable economic, ecological, and environmental benefits. Bark beetles have been recognized as one of the major causes of forest disturbance, and climate change can exacerbate their impact, leading to more tree mortality. Early detection of bark beetle attacks is vital to reduce forest loss and devastating consequences. This study examines th
Tillgång till pollinerare är avgörande för produktionen av många grödor. Det är viktigt att känna till olika insektsarters egenskaper och att skapa förutsättningar för en mångfald av pollinerare. Det kan i vissa situationer uppstå risk för konkurrens mellan vilda bin och honungsbin.
