Climate change-related acute or long-term drought stress can weaken forest ecosystems and result in widespread bark beetle infestations. Eurasian spruce ( Ips typographus L.) infestations have been occurring Norway [ Picea abies (L.) Karst.]-dominated forests central Europe including the Czechia. These appear regularly, especially homogeneous stands, impact varies with climate-induced water conditions. The removal of infected trees before beetles leave is an important step pest management....
Understanding the complex contributions of several factors to an urban heat island is crucial for assessing impacts planning on thermal conditions within cities. It relatively well-known how different work separately, but they together, especially near water bodies, still unclear. This paper investigates effects blue bodies (rivers or large lakes), normalized difference vegetation index (NDVI), building coverage (BC), and height (BH) land surface temperature (LST), comparing situation around...
The global distribution of Pistacia is correlated to its adaptability environmental conditions and mechanisms that had driven the genus current unique narrow latitudinal belt in between 10° North 45° North. geostatisitcal maps are shown derived probability over a period 121 Kyr before present year 2100 were calculated. tolerance trees harsh climate was related leaf phenology, evergreeness vs deciduousness, which has led geographic classification two corresponding sections corroborate recent...
Biological invasion is a major contributor to local and global biodiversity loss, in particular dune ecosystems. In this study we evaluated current future cover expansion of the invasive plant species, Heterotheca subaxillaris, Acacia saligna, Mediterranean coastal plain Israel. This first effort quantify surface focal species area. We reconstructed for 1990–2020 using Landsat time series modeled potential cellular automata (CA) modeling. The overall accuracy results varied range 85–95%...
The Aral Sea ecological crisis resulted from the USSR government decision in 1960s to deploy agricultural project for cotton production Central Asia. Consequently water flow decreased drastically due regulation of Amydarya and Syrdarya Rivers irrigation purposes 55-60 km3 1950s 43 1970s, 4 1980s 9-10 2000s. Expert land cover classification approach gives opportunity use unlimited variable purposes. band algebra (band5/band4 Band4/Band3) remote sensing indices (Normalized differential...
Abstract Filtering approaches on Global Ecosystem Dynamics Investigation (GEDI) data differ considerably across existing studies and it is yet unclear which method the most effective. We conducted an in‐depth analysis of GEDI's vertical accuracy in mapping terrain canopy heights three study sites temperate forests grasslands Spain, California, New Zealand. started with unfiltered (2,081,108 footprints) describe a workflow for filtering using Level 2A parameters geolocation error mitigation....
The research presented stemmed from the observations that female plants of annual dioecious Mercurialis annua outlive male plants. This led to hypothesis M. would be more tolerant stress than was addressed in a comprehensive way, by comparing morphological, biochemical and metabolomics changes during their development under salinity. There were practically no differences between genders vegetative physiological parameters. However, salinity conditions, produced significantly new reproductive...
Hyperspectral remote sensing (RS) and images of various spatial resolution open new vistas for classification mapping trees. These approaches would improve plant in a complex population forest trees diverse species, genera, families, as well monitoring commercial orchards. In this work, we used RS indices cellulose, lignin, wax, chlorophyll, carotenoid, anthocyanin species natural forests For proof concept, the were applied to horticultural crop orchards, where error due mixing different is...
Abstract Satellite‐derived global digital elevation models (DEMs) are essential for providing the topographic information needed in a wide range of hydrological applications. However, their use is limited by spatial resolution and vertical bias due to sensor limitations observing bare terrain. Significant efforts have been made improve DEMs (e.g., TanDEM‐X) create bare‐earth FABDEM, MERIT, CEDTM). We evaluated accuracy Central European mountains submontane regions, assessed how DEM...
Abstract Understanding the causes of spread overabundant species plays a key role in deciphering their invasion mechanisms, while providing managers with targeted management actions to control spread. The objective this research was quantify Hooded Crow (Corvus cornix) Israel and elucidate its Long-term occurrence data sightings were used analyze range expansion rate. This dataset analyzed climatic, normalized difference vegetation index (NDVI), land-use variables. Analysis opportunistic...
Abstract Intensive use of agricultural land often modifies the landscape by dividing continuous natural habitat into smaller and more isolated patches. While it is widely recognized that fragmentation a main cause species extinction, less known about how this impacts function organisms do persist in modified environment. Understanding these effects complicated fact can affect directly but also indirectly, altering patch microclimatic conditions. Here, we integrate satellite image analysis,...
