Wood is one of the key forest Ecosystem Services (ES) of growing ecological, social and economic importance; therefore, we need more precise information about its long-term usage. To achieve this, it is necessary to examine the spatio-temporal aspect

Abstract Changes in natural land cover have been pronounced in the last 12,000 years, and land use has intensified in the last century owing to anthropogenic pressures on landscapes. This trend has led to concomitant changes in the abiotic templates

Species richness and spatial variation in community composition (i.e., beta diversity) are key measures of biodiversity. They are largely determined by natural factors, but also increasingly affected by anthropogenic factors. Thus, there is a need fo

In physical geography, the focus of research is on the natural processes of the Earth which provide the physical settings for human activities. Technical innovations like geographical information system (GIS) and remote sensing combined with statisti

Geodiversity is an emerging, multi-faceted concept in Earth and environmental sciences. Knowledge on geo-diversity is crucial for understanding functions of natural systems and in guiding sustainable development. Despite the critical nature of geodiv

This far, quantitative assessments of geodiversity have typically been conducted on the level of alpha geodiversity (i.e., the variety of geofeatures, such as rock types or landforms, in a location) or gamma geodiversity (i.e., sum of all geofeatures

It has long been debated why groups such as non-avian dinosaurs became extinct whereas mammals and other lineages survived the Cretaceous/Paleogene mass extinction 66 million years ago. We used Markov networks, ecological niche partitioning, and Eart
