Time Dependence of Outcomes in the SPCG-4 Randomized Trial Comparing Radical Prostatectomy and Watchful Waiting in Early Prostate Cancer Open
We synthesized life-long trends for outcome measures following radical prostatectomy or watchful waiting in the SPCG-4 trial, which randomized 695 patients with early prostate cancer to radical prostatectomy (RP) or watchful waiting (WW) f…

Plant ecotypes in the 21st century: from local adaptation to speciation and conservation Open
The concept of ecotypes, genetically distinct entities within species connected to specific habitat types, has been an important source for research and debate since its introduction by the Swedish geneticist Göte Turesson in the early 192…

Dressed for the occasion! Ecotypic divergence, phenotypic plasticity and taxonomic value of capitulum characters of <i>Scorzoneroides autumnalis</i> (Asteraceae) Open
Scorzoneroides autumnalis is a highly polymorphic perennial with several described infraspecific taxa, largely differing in involucre colour and indumentum intensity. Here, we examine the role of ecotypic divergence and phenotypic plastici…

Evolvability and trait function predict phenotypic divergence of plant populations Open
Understanding the causes and limits of population divergence in phenotypic traits is a fundamental aim of evolutionary biology, with the potential to yield predictions of adaptation to environmental change. Reciprocal transplant experiment…

Nutrient losses over time via surface runoff and subsurface drainage from an agricultural field in northern Sweden Open
Nitrogen (N) and phosphorus (P) losses, via both surface runoff and subsurface drainage water, were monitored in an agricultural field in northern Sweden for 32 yr. The objective was to determine losses of N and P in a long‐term perspectiv…

Long-Term Impact of Liming on Soil C and N in a Fertile Spruce Forest Ecosystem Open
Liming can counteract acidification in forest soils, but the effects on soil C and N pools and fluxes over long periods are less well understood. Replicated plots in an acidic and N-rich 40-year-old Norway spruce ( Picea abies ) forest in …

Direct and indirect selection on mate choice during pollen competition: Effects of male and female sexual traits on offspring performance following two‐donor crosses Open
Mate choice in plants is poorly understood, in particular its indirect genetic benefits, but also the direct benefits of avoiding harmful matings. In the herb Collinsia heterophylla , delayed stigma receptivity has been suggested to enhanc…

The evolution of spring fen ecotypes in Rhinanthus: genetic evidence for parallel origins in Scandinavia after the last ice age Open
Locally adapted ecotypes can constitute an important part of the biodiversity, especially in young floras with few endemic species. However, the origins, distinctness and conservation value of many ecotypes remain uncertain because genetic…

Recent changes in the frequency of plant species and vegetation types in Scania, S Sweden, compared to changes during the twentieth century Open
Based on data from three surveys of the vascular flora of the province of Scania, southernmost Sweden, conducted 1938–1971, 1987–2006 and 2008–2015, we analyse the change in frequency of individual species and groups of species associated …

Impact of the North Atlantic Oscillation on Swedish Winter Climate and Nutrient Leaching Open
The winter climate in northwestern Europe is commonly influenced by the North Atlantic Oscillation (NAO). Its intensity, expressed as an index (NAO i ), has been suggested for use in assessing nutrient leaching from arable land to water an…

Value chain for production of bio-oil from kraft lignin for use as bio-jet fuel Open
The LignoJet project aimed to achieve an intermediate lignin-oil product miscible with fossil feedstock and with a significantly reduced oxygen content. A technical concept for production has been studied that involves combined catalysed d…

The 3-D Structural Basis for the Pgi Genotypic Differences in the Performance of the Butterfly Melitaea cinxia at Different Temperatures Open
Although genotype-by-environment interaction has long been used to unveil the genetic variation that affects Darwinian fitness, the mechanisms underlying the interaction usually remain unknown. Genetic variation at the dimeric glycolytic e…

Nongenetic Inheritance of Induced Resistance in a Wild Annual Plant Open
Nongenetic inheritance (e.g., transgenerational epigenetic effects) has received increasing interest in recent years, particularly in plants. However, most studies have involved a few model species and relatively little is known about wild…
