Soil texture is one of the most important soil properties as it drives several physical, chemical, biological, hydrological, and mechanical properties, processes. In Antarctica controls different ecological processes, such carbon stocks, nutrient leaching, toxic metals retention. Thus, there a pressing need for accurate data Antarctic ice-free areas, especially under pressures imposed by climate changes human disturbances on continent. this work, we predicted distribution sand, silt, clay...
Global soil carbon maps are essential to understanding the global cycle and supporting policy decisions, but their uncertainty in remote areas with limited data remains a significant challenge. Assessing quantifying at regional level can shed light on existing uncertainties maps, providing more dependable information for stakeholders. Therefore, this study aimed model map organic (SOC) stock western Amazon, Rondônia state, which witnessed loss of 30% its native coverage last 35 years. We...
RESUMO Este trabalho apresenta um modelo para determinar a fragilidade ambiental em bacias hidrográficas. O estudo foi realizado na Bacia do Rio Aldeia Velha, RJ, localizada zona de contato e transição entre baixada litorânea o relevo montanhoso da Serra Mar. Fatores que influenciam ocorrência processos erosivos foram integrados por algoritmos SIG construção classes fragilidade. A análise multicriterial considerou numérico terreno, dados oficiais sobre variáveis ambientais, imagem orbital...
Increasingly, applications of machine learning techniques for digital soil mapping (DSM) are being used different purposes. Considering the variety models available, it is important to know their performance in relation data and environmental variables involved mapping. This paper investigated eight algorithms a tropical mountainous area an official rural settlement Zona da Mata region Brazil. Morphometric maps generated from elevation model, together with Landsat-8 satellite imagery,...
The Juçara palm (Euterpe edulis Mart.) is a native species of the Atlantic Forest biome, with high commercial value due to, among other uses, extraction heart and pulp. This has essential ecological interaction fauna, providing food for many frugivorous species. However, it on list endangered species, mainly to disorderly exploration tree heart, but also climate change, habitat fragmentation, defaunation. In this context, understanding which areas are suitable grow important planning...
Background and Methods: We assessed the prokaryotic eukaryotic diversity present in non-vegetated vegetated soils on King George Island, Maritime Antarctic, combination with measurements of carbon dioxide fluxes. Results: For prokaryotes, 381 amplicon sequence variants (ASVs) were assigned, dominated by phyla Actinobacteriota, Acidobacteriota, Pseudomonadota, Chloroflexota, Verrucomicrobiota. A total 432 ASVs including representatives from seven kingdoms 21 phyla. Fungi communities, followed...
Abstract This study aimed to test two hypotheses: (i) on the Brazilian semiarid territory, climate has greater weight as a driver of vegetation than soil and; (ii) arboreal Caatinga is whose environmental attributes are similar Dry Forest, in terms and attributes. We analyzed superficial horizon 156 standardized profiles distributed throughout region. Bioclimatic variables were obtained from WorldClim platform extracted location. The main types region considered: Caatinga, Forest Cerrado....
ABSTRACT Two reports of Antarctic region potential new record high temperature observations (18.3°C, 6 February 2020 at Esperanza station and 20.8°C, 9 a Brazilian automated permafrost monitoring on Seymour Island) were evaluated by World Meteorological Organization (WMO) panel atmospheric scientists. The latter figure was reported as 20.75°C in the media. considered synoptic situation instrumental setups. It determined that large pressure system over area created föhn conditions resulted...
Digital soil mapping (DSM) has been increasingly used to provide quick and accurate spatial information support decision-makers in agricultural environmental planning programs. In this study, we a DSM approach map soils western Haiti compare the performance of Multinomial Logistic Regression (MLR) with Random Forest (RF) classify soils. The study area 4,300 km2 is mostly composed diverse limestone rocks, alluvial deposits, and, lesser extent, basalt. A survey was conducted whereby were...
Abstract The detailed geomorphology of ice‐free landscapes Antarctica is key to understanding how their highly fragile environments respond climate change, at different temporal and spatial scales. Despite the recent advances in geomorphological studies areas, machine learning applications produce landform maps are still scarce on Antarctic continent. In this study, we evaluated predictive performance supervised algorithms digital Vega Island—Antarctic Peninsula region. We tested six models:...
