In this paper, a novel method for analysing a bird’s song is presented. The song of male great reed warblers is used for developing and testing the methods. A robust method for detecting syllables is proposed and a classification of those syllables as compared to reference syllables is done. The extraction of classification features are based on the use of singular vectors in different time-freque
Mot en ny världsordning? Orsaker till östblockets sönderfall och Sovjetunionens upplösning: · Ekonomisk bankrutt, höga utlandslån · Ideologins (Sovjetkommunismens) söndervittring · Man missade utvecklingen mot den nya ekonomin och informationsteknologin, blev kvar i gamla modeller med mycket tung industri · Kostsam kapprustning (Reagan, SDI) · Ekonomisk integration öst/väst (Hobsbawm) · Allt stark

During an infection, the genetic composition of the pathogen population in the host might range from clonal to genetically diverse, depending on the genetic variation of the inoculum, mutation events, genetic drift, and host selection during the course of the infection. Variation in the genetic diversity of avian malaria parasites, both within and between individual hosts, is not well documented.
Avian genomes are typically stable, yet instances of chromosome fissions, fusions and translocations are known across various lineages. For example, multiple sex chromosome translocations have been described in the superfamily Sylvioidea. In this study, we examine the sex chromosomes in two Sylvioidea families, Nicatoridae and Cisticolidae, using whole-genome data. We found sex-linkage of chromoso
Seagrass meadows are recognized for their coastal protection services in terms of reducing the wave runup level and limiting coastal erosion. This study aims to quantify these services for a dense seagrass meadow located in a non-tidal, fetch-limited sea. A year-long field campaign was conducted to collect data on wave statistics along the cross-shore direction of the seagrass meadow, bathymetry,
Stable isotope analysis (N and C) of fossil cereal grains is regularly explored as a means of obtaining insights to past crop growing conditions and agricultural practices. In this study, we assessed how several growth conditions can affect δ15N and δ13C values of modern cereal grain with the aim to help understand isotopic values from ancient cereal remains. We investigated the impact of fertiliz
Background The prevalence of mental health issues is rising, especially among youth. Research shows that diagnosable and subthreshold mood disorder symptoms are increasing. Notably, and particularly troublesome, there are indications that some mental health issues, such as non-suicidal self-injury (NSSI) and disordered eating (DE) behaviors, have increased during the last decades, these reports, h
Global warming may prolong and intensify the thermal growing season of vegetation. It is not yet clear how the Paris Agreement's long-term temperature goals will affect the thermal growing season of vegetation, particularly crops, in China. Based on the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) datasets and the Global Gridded Crop Model Intercomparison (GGCMI) phase 1 dataset, w
Islands are among the last regions on Earth settled and transformed by human activities, and they provide replicated model systems for analysis of how people affect ecological functions. By analyzing 27 representative fossil pollen sequences encompassing the past 5000 years from islands globally, we quantified the rates of vegetation compositional change before and after human arrival. After human
Increasing atmospheric carbon dioxide concentration [CO2] caused by anthropogenic activities has triggered a requirement to predict the future impact of [CO2] on forests. The Hindu Kush Himalayan (HKH) region comprises a vast territory including forests, grasslands, farmlands and wetland ecosystems. In this study, the impacts of climate change and land-use change on forest carbon fluxes and vegeta
The thawing and subsequent decomposition of large stocks of soil organic carbon (SOC) currently stored in the northern circumpolar permafrost region are projected to result in a ‘positive’ feedback on global warming. The magnitude of this feedback can only be assessed with improved knowledge about the total size and geographic distribution of the permafrost SOC pool. This study investigates SOC st
Monitoring of forest carbon fluxes for the purpose of national greenhouse-gas inventorying and reporting are commonly based on repeated large-scale field measurements. Alternate approaches based on modelling of forest growth offers potential benefits such as cost savings and detailed assessments of involved carbon fluxes. We calculated the net primary productivity (NPP) of Swedish forests using tw
Understanding communication and signalling has long been strived for in studies of animal behaviour. Many songbirds have a variable and complex song, closely connected to territory defence and reproductive success. However, the quantification of such variable song is challenging. In this paper, we present a novel, automated method for detection and classification of syllables in birdsong. The meth
In this study, a sediment sequence from Lake Skottenesjön, southern Sweden was investigated to reconstruct the effect of forestry and land-use on erosion rates and delivery of organic and minerogenic matter to the lake. Catchment-scale vegetation changes during the last 1000 years were reconstructed quantitatively using pollen analysis and the Landscape Reconstruction Algorithm (LRA). Organic matt
While deforestation and forest degradation have gained attention in recent years not least at the UN climate negotiations, a third “de”, i.e., defaunation, has to a great extent been overlooked. Human-induced faunal loss does not only reduce tree species diversity, but also significantly erodes key ecosystem services and functions and further disadvantages local communities. In this article, we an
Anthropogenic land cover change (ALCC) is the most important transformation of the Earth system that occurred in the preindustrial Holocene, with implications for carbon, water and sediment cycles, biodiversity and the provision of ecosystem services and regional and global climate. For example, anthropogenic deforestation in preindustrial Eurasia may have led to feedb
The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot.
