Assessing Chile's national expansion of urban and artificial coverages between 2000 and 2022 [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
This study investigates the national expansion of urban and artificial coverages in Chile between 2000 and 2022 using remote sensing techniques. The research employed Google Earth Engine and Landsat imagery to classify land use and land cover (LULC ...

The importance of individual movement and feeding behaviour for long-distance seed dispersal by red deer: a data-driven model

Movement Ecology, 2020
Background Long-distance seed dispersal (LDD) has strong impacts on the spatiotemporal dynamics of plants. Large animals are important LDD vectors because they regularly transport seeds of many plant species over long distances.

Mapping and assessing ecosystems and their services: a comparative approach to ecosystem service supply in Suriname and French Guiana

Ecosystems and People, 2021
Current environmental resource management policies acknowledge the need to manage and conserve biodiversity. Sustaining good ecosystem conditions and ecosystem services (ES) is imperative at and across multiple spatial scales.

Tapping the tree-ring archive for studying effects of resin extraction on the growth and climate sensitivity of Scots pine

Forest Ecosystems, 2017
Background In the German Democratic Republic (GDR), resin tapping in Scots pine (Pinus sylvestris L.) forests was a major economic activity, and resin-tapped stands are frequently found up until this day.

As good as human experts in detecting plant roots in minirhizotron images but efficient and reproducible: the convolutional neural network “RootDetector”

Scientific Reports, 2023
Plant roots influence many ecological and biogeochemical processes, such as carbon, water and nutrient cycling. Because of difficult accessibility, knowledge on plant root growth dynamics in field conditions, however, is fragmentary at best ...

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants

FEBS Open Bio, EarlyView.
Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

An insight into the pivotal roles of ubiquitination in mediating plant responses to heat stress through diverse pathways and modules

Chemical and Biological Technologies in Agriculture
Rising ambient temperatures associated with global climate change present a major threat to plant productivity by imposing heat stress (HS) that disrupts cellular, biochemical, and molecular processes in plants. HS leads to protein unfolding, aggregation,
