Estimation of district-level spring barley yield in southern Sweden using multi-source satellite data and random forest approach

Remote sensing observations and artificial intelligence algorithms have emerged as key components for crop yield estimation at various scales during the past decades. However, the utilization of multi-source satellite data and machine learning for estimating aggregated crop yield at the regional level in Europe has been only scarcely explored. Our study aims to bridge this research gap by focusing

Brown bear population densities in the Slovenian Dinaric mountains estimated with the use of camera traps from 2018 to 2023

Understanding the dynamic of a population via either abundance or density is crucial for wildlife conservation. The brown bear (Ursus arctos) is a commonly distributed, yet elusive species, playing a major role in the ecosystem. Usually monitored with genetic sampling, hunted bags, or telemetry data, the use of camera traps for bear monitoring is still to this day a rarely used, yet promising meth

Seedling Growth and Seed Characteristics of Salvia corrugata and Macleania rupestris – potential for restoration of abandoned land in Ecuador

Restaurering av betesmarker i Ecuador: Växtkrav för Salvia corrugata och Macleania rupestris Övergivna betesmarker och fält i det syd-andinska landskapet i Ecuador har ofta under lång tid utsätts för urlakning av näringsämnen och jordpackning, något som begränsar den naturliga etableringen av träd och buskar. Då mängden övergiven mark ökar blir landskapet alltmer fragmenterat och inhemska växt arThe Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi

Identification, Characterization, and Antibacterial Evaluation of Five Endophytic Fungi from Psychotria poeppigiana Müll. Arg., an Amazon Plant

Endophytic fungi, residing within plants without causing disease, are known for their ability to produce bioactive metabolites with diverse properties such as antibacterial, antioxidant, and antifungal activities, while also influencing plant defense mechanisms. In this study, five novel endophytic fungi species were isolated from the leaves of Psychotria poeppigiana Müll. Arg., a plant from the R

Growing the seeds of pebble accretion through planetesimal accretion

We explore the growth of planetary embryos by planetesimal accretion up to and beyond the point at which pebble accretion becomes efficient at the so-called Hill-transition mass. Both the transition mass and the characteristic mass of planetesimals that formed by the streaming instability increase with increasing distance from the star. We developed a model for the growth of a large planetesimal (

Metabolic Rates and Nighttime Energy Saving in Long-Distance versus ShortDistance Migratory Passerines

Billions of birds migrate thousands of kilometres twice a year. The migration is an energetic challenge, with over 70% of the total energy expenditure being spent at stopover sites. There are different strategies birds can use to conserve energy, such as reducing the metabolic rate. This study aimed to investigate the potential nighttime energy saving in long-distance versus short-distance migrati

Heated fibre optics to monitor soil moisture under successive saturation–drying cycles : An experimental approach

In recent decades, distributed temperature sensing (DTS) has emerged as a robust technology for environmental applications, enabling high-resolution temperature measurements along fibre optic cables (FOCs). The actively heated fibre optic (AHFO) method is employed to monitor soil moisture ((Formula presented.), m3 m−3), wherein the soil temperature subsequent to the application of a heat pulse is
