Habitat selection can be considered as a hierarchical process in which animals satisfy their habitat requirements at different ecological scales. Theory predicts that spatial and temporal scales should co‐vary most processes the limiting factors drive coarse scales, but less influential finer Using detailed location data on roe deer Capreolus capreolus inhabiting Bavarian Forest National Park, Germany, we investigated several We tested 1) whether time‐varying patterns were governed by...
Alien invasive species can affect large areas, often with wide-ranging impacts on ecosystem structure, function and services. Prunus serotina is a widespread invader of European temperate forests, where it tends to form homogeneous stands limits recruitment indigenous trees. We hypotesized that invasion by P. would be reflected in the nutrient contents native species' leaves respiration invaded plots as efficient resource uptake changes cycling probably underly its aggressive invasiveness....
Abstract Aim To propose a species distribution modelling framework and its companion “ iSDM ” R package for predicting the potential realized distributions of invasive within invaded range. Location Northern France. Methods The non‐equilibrium with environment range affects environmental representativeness presence–absence data collected from field introduces uncertainty in observed absences as these may either reflect unsuitable sites or be incidental. address issues, we here an systematic...
The combination of GPS-Telemetry and resource selection functions is widely used to analyze animal habitat selection. Rapid large-scale assessment vegetation structure allows bridging the requirements studies on grain size extent, particularly in forest habitats. For roe deer, cold period winter forces individuals optimize their trade off searching for food shelter. We analyzed deer (Capreolus capreolus) a montane landscape combining estimates cover three different height strata, derived...
With the increasing threat of wildfires globally, improving availability accurate, spatially explicit fuel type information is critical for fire behavior predictions that can support management decisions to mitigate hazards. Since mapping surface types using airborne or spaceborne sensors relies on ground truth data from laborious field assessments, here we propose a novel proximate sensing-based approach classifying in-forest RGB photographs convolutional neural networks (CNNs). We test...
Abstract. The large-scale mapping of plant biophysical and biochemical traits is essential for ecological environmental applications. Given its finer spectral resolution unprecedented data availability, hyperspectral has emerged as a promising, non-destructive tool accurately retrieving these traits. Machine particularly deep learning models have shown strong potential in from data. However, when deploying methods at large scales, reliably quantifying associated uncertainty remains critical...
Light detection and ranging (lidar) is a useful tool for measuring three-dimensional habitat structure; hence, its use in suitability models has been explored, both as single resource combination with other remote-sensing techniques. Here, we evaluated the of airborne lidar data comparison aerial photographs field surveys modelling distribution an endangered cryptic forest species, hazel grouse (Bonasa bonasia). The study was conducted Bavarian Forest National Park southeast Germany....
Mountain ecosystems are biodiversity hotspots that increasingly threatened by climate and land use/land cover changes. Long-term monitoring programs provide unique insights into resulting adverse impacts on plant animal species distribution. Species distribution models (SDMs) in combination with satellite remote sensing (SRS) data offer the opportunity to analyze shifts of distributions response these changes a spatially explicit way. Here, we predicted presence probability three different...
Abstract Tree decline in arid and semi-arid forest ecosystems causes severe socioeconomic ecological problems thus needs to be thoroughly quantified monitored across space time. This study investigates tree Iran’s Zagros forests, considering environmental factors (e.g. topographic, soil, climatic variables). We used field data from Chaharmahal-and-Bakhtiari (a area covering 165 km2) derived freely available databases. Relationships between tree, decline, were analyzed using generalized...
Abstract Temperate forests of Central Europe are exposed to increasing fire risk. However, little is known about combustion properties leaf litter, which plays an important role in the spread surface fires. We used cone calorimetry compare litter samples from seven common tree species European by reconstructing a layer original depth sample holders with size 10 cm × cm. In addition mono-specific beds, experiments included mixtures different types, and bryophytes one mixture fine woody...
Abstract Rising temperatures and an expected increase in the frequency of droughts heat waves have raised concerns about forest fires cool-temperate humid-continental regions. This concern is accompanied by a lack detailed knowledge fire behaviour ecology many these A special issue ‘Forest forests’ was launched early 2022 Forestry to collect studies that address existing gaps. The featured research papers cover several topics related remotely-sensed field-based fuel assessment, flammability...
The synergies between remote sensing technologies and ecological research have opened new avenues for the study of alien plant invasions worldwide. Such scientific advances greatly improved our capacity to issue warnings, develop early-response systems assess impacts on biodiversity ecosystem functioning. Hitherto, practical applications approaches support nature conservation actions are lagging far behind advances. Yet, some these technologies, knowledge transfer is difficult due complexity...
