Fire is a significant agent of landscape transformation on Earth, and dynamic ephemeral process that challenging to map. Difficulties include the seasonality native vegetation in areas affected by fire, high levels spectral heterogeneity due spatial temporal variability burned areas, distinct persistence fire signal, increase cloud smoke cover surrounding difficulty detecting understory signals. To produce large-scale time-series area, robust number observations more efficient sampling...
The Brazilian Cerrado is a heterogeneous region of open ecosystems adapted to fire intermingled with patches woody growth-forms, high levels biodiversity and endemism. In recent decades, land conversion human activities have proliferated across the Cerrado, losing about half its original area. These changes, coupled climate change, are altering regimes uncertain, but possibly adverse, consequences for ecosystems. Here, we used burned area data characterize each cell on 30 km grid over...
Abstract Background Fire significantly transforms ecology and landscapes worldwide, impacting carbon cycling, species interactions, ecosystem functions. In the Brazilian Cerrado, a fire-dependent savanna, interaction between fire, society, environment is evident. Given that wildfires contribute to greenhouse gas emissions, our study aimed analyze four decades of burned area data understand changes in fire dynamics, using Collection 2 annual MapBiomas maps (1985 2022). Our examined...

Abstract Caatinga's conservation and biodiversity are threatened due to the intensification of anthropic activities climate change. The mammals have different responses seasonal changes, however particularly in Caatinga, these effects still poorly understood. We assessed influence (distance from urban areas wind farms), environmental water), (Normalized Difference Vegetation Index (NDVI) land surface temperature (LST)) variables on number records richness medium large‐sized Brazilian...
Atualmente o domínio Cerrado no Brasil apresenta apenas 20% da sua cobertura original, onde 8,21% estão em áreas protegidas. Deste total, 1% se encontra estado de São Paulo, protegidas propriedades particulares ou categorias unidades conservação. Frente a estas condições ambientais e riqueza deste sistema, é considerado um dos 25hotspots terrestres mais importantes para Apesar esforços conservação, esse enfrenta diversos problemas com invasão espécies exóticas, como as do gênero Pinus. Tendo...
The use of optical remote sensing to monitor short-term postfire dynamics in rapidly recovering ecosystems is a complex task, requiring strong spectral separability and high temporal resolution. Thus, characterizing the effects lag image acquisitions relation fire occurrence fundamental importance improve our understanding how fire-related environmental ecological processes are connected multitemporal information. We used harmonized series Sentinel-2A/2B Landsat-7/8 images paired with...
O presente trabalho aborda a problemática da invasão biológica vegetal em unidade de conservação proteção integral. No caso Estação Ecológica Itirapina houve ao longo das últimas décadas do gênero Pinus oriundo principalmente atividades pesquisa e produção florestal, com variadas espécies spp na Experimental Itirapina. Esta florestal estadual encontra-se contígua à estação ecológica. Para tanto, apresenta uma proposta manejo baseada corte raso espécie invasora monitoramento terrestre aéreo...
