  • Darkness as an Endangered Species: Why Light Pollution Matters

    Darkness as an Endangered Species: Why Light Pollution Matters

    Author: Tomáš Klouček Darkness, once an integral part of life on Earth, is now rapidly vanishing. The spread of artificial lighting—often excessive, misdirected, or poorly regulated—has created a form of pollution that is both overlooked and far-reaching. Known as light pollution, it disrupts ecosystems, affects human health, and fundamentally alters our relationship with the night…

    Early Research Mobility Experiences: My Visit Exchange to Bonn

    Author: Michal Kučera To make the most of my PhD journey, I sought early experience through a short research exchange at the University of Bonn. I wanted to immerse myself in a concentrated research environment, which I believed would help me refine my research concept and uncover connections with other scholars’ work. By engaging with…

  • Why Timing Matters: How seasonal changes shape bird species distribution models

    Why Timing Matters: How seasonal changes shape bird species distribution models

    Author: Dominika Prajzlerová Species Distribution Models (SDMs) are powerful tools that help scientists understand where species live—and why—by linking species occurrences to environmental conditions. These models often use remote sensing (RS) data from satellites to describe habitat conditions across large areas. But one key question often goes overlooked: When is the best time to acquire…

  • Tracking the Hidden Climate Impact of Invasive Plants

    Tracking the Hidden Climate Impact of Invasive Plants

    Author: Giorgi Kozhoridze A joint research initiative between the Czech University of Life Sciences in Prague and Tel Aviv University aimed to explore a frequently neglected impact of invasive plant species: their capacity to alter the local climate. Concentrating on the delicate coastal sand dunes of the eastern Mediterranean, the research investigated how two invasive…

  • How Ground-Based LiDAR Is Transforming Forest Inventories

    How Ground-Based LiDAR Is Transforming Forest Inventories

    Author: Juan Alberto Molina Valero These days, with drones and satellites capturing stunning views from above, it’s easy to forget that some of the most powerful tools for understanding our forests are still on the ground. In our recent study, we explored how a ground-based laser scanning tool—called terrestrial laser scanner (TLS)—can help us measure…

  • Lidar in Students‘ Final Theses

    Lidar in Students‘ Final Theses

    Author: Vitezslav Moudry Recent months have been marked by the completion and evaluation of student theses. It should come as no surprise that the students I have supervised have often worked with laser altimetry data in some way and that these theses are closely related to what we are doing in EarthBridge. Two studies validated…

  • When Wind Blows

    When Wind Blows

    Author: Jan Komárek Drones have revolutionised environmental monitoring, promising on-demand, high-resolution data collection in places satellites can’t reach. But beneath the hype lies a harsher reality: weather. I analysed meteorological records from 31 Czech locations (2016–2024) and found that drones are actually grounded about 75 % of the time. Here’s why—and what we can do…

  • Experience from the Polar Winter School – Remote Sensing in Arctic Conditions

    Experience from the Polar Winter School – Remote Sensing in Arctic Conditions

    Author: Jan Komárek From March 2nd to 8th, 2025, we had the opportunity to participate in the 2nd Polar Winter School in Hvanneyri, Iceland, organized by the Czech University of Life Sciences Prague in collaboration with Landbúnaðarháskóli Íslands and the Nordic Snow Network. The event brought together students and experts from 14 countries, focusing on…

  • Spectral Characterization of Bird Habitats: Research Exchange at the University of Bonn

    Spectral Characterization of Bird Habitats: Research Exchange at the University of Bonn

    Author: Richard Bittman As part of the „Building Bridges between Earth Observation and Environmental Sciences“ project, I recently completed a research exchange at the University of Bonn with Prof. Anna Cord’s team. This collaboration strengthened my doctoral research on avian habitat characterization using remote sensing techniques. With Prof. Anna Cord Research Focus My work addresses…

  • Spectral diversity beyond the Spectral Variation Hypothesis: what comes next?

    Spectral diversity beyond the Spectral Variation Hypothesis: what comes next?

    Author: Michela Perrone Nearly three decades ago, the Spectral Variation Hypothesis (SVH) proposed a tremendously simple idea: the spectral diversity of vegetated landscapes (essentially, the spatial variation in reflectance detected by remote sensing) could serve as a proxy for plant species richness​. The promise of biodiversity mapping from space quickly gained traction, especially with multispectral…
