Soil pH is one of the most influential variables in soil, and is a powerful factor in influencing the size, activity and community structure of the soil microbial community. It was previously shown in a century old artificial pH gradient in an arable soil (pH 4.0-8.3) that bacterial growth is positively related to pH, while fungal growth increases with decreasing pH. In an attempt to elucidate som
There is growing evidence of the importance of extramatrical mycelium (EMM) of mycorrhizal fungi in carbon (C) cycling in ecosystems. However, our understanding has until recently been mainly based on laboratory experiments, and knowledge of such basic parameters as variations in mycelial production, standing biomass and turnover as well as the regulatory mechanisms behind such variations in fores
Secondary hole-nesting birds that do not construct nest holes themselves and hence regularly breed in nest boxes constitute important model systems for field studies in many biological disciplines with hundreds of scientists and amateurs involved. Those research groups are spread over wide geographic areas that experience considerable variation in environmental conditions, and researchers provide
Measuring results and outcome in social work: A casestudy on the application of the outcome measurement tool Forandringskompasset in the homelessness services in the municipality of Copenhagen [translated title] The aim of this study was to examine how New Public Management inspired outcome measurement tools is applied and understood by respectively the administrative management and the professio
The alarming rates of extinction and degrading ecosystems call for new means of understanding and accounting for how people depend on nature. Ecosystem services (ES) is a contested but widely applied concept aiming to connect ecosystem functions to human wellbeing and to assess and account for how nature matters in decision-making. More diverse frameworks and ideas of value intended for assessment
Recent studies suggest that oncogenic processes (from precancerous lesions to metastatic cancers) are widespread in wild animal species, but their importance for ecosystem functioning is still underestimated by evolutionary biologists and animal ecologists. Similar to what has been observed in humans, environmental modifications that often place wild organisms into an evolutionary trap and/or expo
The mineralo-sphere is an important micro habitat in terrestrial ecosystems. How different groups of microorganisms colonise mineral surfaces and whether the level of grassland land-use intensity (LUI) modifies this micro-habitat is not well known, however. We exposed mesh containers filled with pristine soil minerals (illite/goethite) mixed with 13C labelled root litter of Dactylis glomerata and
As urban areas continue to grow, understanding how species respond and adapt to urban habitats is becoming increasingly important. Knowledge of the mechanisms behind observed phenotypic changes of urban-dwelling animals will enable us to better evaluate the impact of urbanization on current and future generations of wildlife and predict how animals respond to novel environments. Recently, urban ec
Älska Skog educational competition (Gothenburg, Sweden)Gothenburg-based educational institute Universeum is running annual design competitions on forest topics for primary school pupils, starting in 2016. Based on various activities in which pupils gain knowledge about forest-related challenges and opportunities as well as forestry, they would design plans to deal with those problems. After a firs
Hybridization is increasingly recognized as a potent evolutionary force. Although additive genetic variation and novel combinations of parental genes theoretically increase the potential for hybrid species to adapt, few empirical studies have investigated the adaptive potential within a hybrid species. Here, we address whether genomic contingencies, adaptation to climate, or diet best explain dive
Assortative mating is of interest because of its role in speciation and the maintenance of species boundaries. However, we know little about how within-species assortment is related to interspecific sexual isolation. Most previous studies of assortative mating have focused on a single trait in males and females, rather than utilizing multivariate trait information. Here, we investigate how intrasp
Forests used for timber production provide essential ecosystem services to society, as well as potential breeding habitat for bird communities. In southern Sweden, 90% of productive forest land is used for timber production and stands dominated by Norway spruce (Picea abies) constitute approximately 40% of the forested area. Due to their homogeneous structure, these spruce production forests are o
Over the past decade, avoiding deforestation has become a central element of the UN Framework Convention on Climate Change (UNFCCC). The focal point of this has been the incentive-based mechanism of REDD+, which stands for Reducing Emissions from Deforestation and forest Degradation. A key notion in REDD+ is to establish incentives for developing countries to reduce their forest-related carbon emi
The avian genus Calandrella (larks) was recently suggested to be non-monophyletic, and was divided into two genera, of which Calandrella sensu stricto comprises 4–5 species in Eurasia and Africa. We analysed mitochondrial cytochrome b (cytb) and nuclear Restriction-site Associated DNA (RAD) sequences from all species, and for cytb we studied 21 of the 22 recognised subspecies, with the aim to clar
The increase in size of human populations in urban and agricultural areas has resulted in considerable habitat conversion globally. Such anthropogenic areas have specific environmental characteristics, which influence the physiology, life history, and population dynamics of plants and animals. For example, the date of bud burst is advanced in urban compared to nearby natural areas. In some birds,
Background: Genome and transcriptome sequencing has greatly facilitated the understanding of biomass-degrading mechanisms in a number of fungal species. The information obtained enables the investigation and discovery of genes encoding proteins involved in plant cell wall degradation, which are crucial for saccharification of lignocellulosic biomass in second-generation biorefinery applications. T
Improving urban liveability and prosperity is commonly set as a priority in urban development plans and policy around the world. Several annual reports produced by international consulting firms, media, and global agencies rank the liveability of cities based on a set of indicators, to represent the quality of life in these cities. The higher is the ranking, the more liveable is the city. In this
Background: Personalization has become an essential tool of video streaming platforms, influencing how users discover and consume content. In highly saturated streaming markets, characterized by extensive content libraries and low switching barriers, personalization systems gain increasing relevance in enhancing customers’ experiences and satisfaction. Purpose: This study aims to explore how per
