This paper focuses on the meticulous selection of optimal remote sensing and climate datasets for Gross Primary Productivity (GPP) estimation in African rangelands. Utilizing Eddy Covariance Flux Tower data, we refine data selection and employ a Light Use Efficiency (LUE) model, with Sentinel 2 for photosynthetically active vegetation quantification, MODIS for Photosynthetically Active Radiation (

This research explores herbaceous biomass estimation in African rangelands through remote sensing, emphasizing challenges and uncertainties. Comparing remote sensing data with ground validation, the study addresses spatiotemporal variations, employing advanced models and validation techniques. Harmonizing and calibrating ground data from four African countries, the research provides insights into

The spatial imprint of forest disturbances, which can result from a variety of anthropogenic and natural causes, is important in shaping the form and function of the world’s forests. However, we lack a systematic assessment of how the forms of forest disturbances differ globally, which could help in sustainable forest policy and management initiatives to protect forest biomes. Here we produce a gl

Increasing water stress is emerging as a global phenomenon, and is anticipated to have a marked impact on forest function. The role of tree functional strategies is pivotal in regulating forest fitness and their ability to cope with water stress. However, how the functional strategies found at the tree or species level scale up to characterise forest communities and their variation across regions

Tree growth and longevity trade-offs fundamentally shape the terrestrial carbon balance. Yet, we lack a unified understanding of how such trade-offs vary across the world's forests. By mapping life history traits for a wide range of species across the Americas, we reveal considerable variation in life expectancies from 10 centimeters in diameter (ranging from 1.3 to 3195 years) and show that the p

Key recommendationsPastureland restoration must be implemented to reduce dependency oncoping mechanisms such as emergency feeding, mechanized transport andintense workloads. These coping mechanisms are increasingly used to dealwith the cumulative effects of encroachments from competing land uses,predator pressure, and the impacts of climate change on snow conditions.Vigorous thinning of dense, man

Forests have seen a strong greening trend worldwide, and previous studies have attributed this mainly to land-use conversions such as afforestation. However, for the greening of existing forests, the role of human interventions is unclear. Here we paired neighboring natural and planted forests in Southern China to minimize the differences between the forest types and analyzed the vegetation index

A method, system and apparatus are disclosed. A network node in communication with a wireless device in a first cell is provided. The network node is configured to receive, from the wireless device, a measurement report associated with the first cell. The network node is further configured to estimate at least one radio resource management, RRM, metric for the first cell and at least one second ce

Uppsatsen undersöker #MeToo som social rörelse med betoning på den deliberativa processen och hur medborgarengagemang skapas genom mobilisering och användning av hashtagen #MeToo. Syftet med denna uppsats är att undersöka hur sociala medier kan vara ett verktyg för politisk kommunikation och hur politisk mobilisering sker i och med den medieteknologiska utvecklingen. Uppsatsen bygger på en fallstu

Jokkmokks kommun har ända sedan 1960-talet haft en negativ befolkningsutveckling. Nu finns det i kommunen planer på att etablera en gruvverksamhet. Detta skulle kunna innebära nya möjligheter för kommunen. Syftet med studien är att undersöka hur Jokkmokks kommun på bästa sätt ska tillgodogöra sig de möjliga positiva samhällseffekter som en gruvetablering kan medföra. De frågor som ställs är: Vad k

Framställningen utgår från frågeställningen hur kallelse till bolagsstämma påverkar bolagsstämmans beslutskompetens. Kallelsen ska innehålla ett förslag till dagordning. Dagordningen i kallelsen har en begränsande funktion för stämmans beslutskompetens genom bestämmelsen i 7 kap. 26 § ABL, vilken föreskriver att stämman inte får fatta beslut i ärenden som inte angivits i dagordningen. Stämman är äThis essay deals with the question to which degree the notice of a general meeting of shareholders limits the meetings powers to make decisions. According to the Companies Act (hereinafter referred to as “ABL”) chapter 7 section 24 the notice must propose, in an agenda, the items which are meant to be dealt with at the general meeting. As a general rule the meeting does not have the power to make

The Global Land-Atmosphere Climate Experiment-Coupled Model Intercomparison Project phase 5 (GLACE-CMIP5) is a multimodel experiment investigating the impact of soil moisture-climate feedbacks in CMIP5 projections. We present here first GLACE-CMIP5 results based on five Earth System Models, focusing on impacts of projected changes in regional soil moisture dryness (mostly increases) on late 21st c

The purpose of the present study was to investigate if a relationship between BMD and testosterone levels could be identified in elite male lightweight rowers. Thirteen male lightweight national team rowers had their BMD measured in a DEXA scanner. Plasma concentrations of total testosterone (TT), free testosterone (IFT), dihydrotestosterone (DHT) and sex hormone binding globulin (SHBG) and additi

This study analyzes the relationship between drought processes and crop yields in Moldova, together with the effects of possible future climate change on crops. The severity of drought is analyzed over time in Moldova using the Standard Precipitation Index, the Standardized Precipitation Evapotranspiration Index, and their relationship with crop yields. In addition, rainfall variability and its re

Climate change and land-use change represent a dual threat to terrestrial ecosystem functioning. In the tropics, forest conversion to agriculture is occurring alongside warming and more pronounced periods of drought. Rainfall after drought induces enormous dynamics in microbial growth (potential soil carbon storage) and respiration (determining carbon loss), affecting the ecosystem carbon budget.

This study is aimed at detecting Parkinson's disease by analyzing voice measurements made using a mobile phone. The key objectives include creating a model that ensures accurate predictions while maintaining interpretability, consistent with the existing literature on Parkinson's disease. We introduce a novel group-wise scaling method to address typical age and biological sex biases in the dataset

Given the important role of the land surface for climate, this study aims at (1) to evaluate the quality of the simulation of surface climate by the land-surface component of the EC-Earth3 ESM and (2) to assess the role of the coupling of the land surface with the atmosphere for the simulation of the surface climate in EC-Earth3. It is based on three simulations with different configurations of th

In this paper, we consider real-time modelling of an underwater acoustic channel impulse response (CIR), exploiting the inherent structure and sparsity of such channels. Building on the recent development to model acoustic channels using a Kronecker structure, we propose a sparse block updating conjugate gradient algorithm. The method initially compensate for the drift common in underwater measure
