THE URBAN HEAT ISLAND OF PORTO ALEGRE, RS, SOUTHERN BRAZIL: AN ANALYSIS BETWEEN 1985 AND 2019 THROUGH THE RADIATIVE TRANSFER IN THE INFRARED THERMAL [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 The objective of this study was to verify the evolution of surface temperature associated with land use and land cover from 1985 to 2019 in Porto Alegre, RS, Brazil. The methodological procedures were performed in five steps: 1.

Modelling dry biomass dynamics in the Cerrado Biome
Biodiversidade Brasileira, 2019 The volume of dry biomass is a key predictor of fire propagation in the Cerrado biome. Traditionally, biomass dynamics is measured directly onsite through field experiment. However, onsite measurements are constrained by costly logistics needed to cover

BioDinamica: a toolkit for analyses of biodiversity and biogeography on the Dinamica-EGO modelling platform [PDF]
PeerJ, 2019 Biogeography and macroecology are at the heart of the debate on ecology and evolution. We have developed the BioDinamica package, a suite of user-friendly graphical programs for analysing spatial patterns of biogeography and macroecology.

Past human‐induced ecological legacies as a driver of modern Amazonian resilience
People and Nature, Volume 5, Issue 5, Page 1415-1429, October 2023., 2023 Abstract People have modified landscapes throughout the Holocene (the last c. 11,700 years) by modifying soils, burning forests, cultivating and domesticating plants, and directly and indirectly enriched and depleted plant abundances. These activities also took place in Amazonia, which is the largest contiguous piece of rainforest in the world, and for

Diversity and Distributions, Volume 29, Issue 9, Page 1190-1204, September 2023., 2023 Abstract Aim Mining is increasingly pressuring areas of critical importance for biodiversity conservation, such as the Brazilian Amazon. Biodiversity data are limited in the tropics, restricting the scope for risks to be appropriately estimated before mineral licensing decisions are made.

Fire propagation model in the cerrado biome
Biodiversidade Brasileira, 2019 To date, there are no model available for fire propagation in the Cerrado. Especially, for helping fire management and prevention, models need to run under near-real time conditions at a local scale.

Biotropica, Volume 55, Issue 2, Page 467-479, March 2023., 2023 We show that vegetation structure can predict species richness and functional diversity in Amazonian mixed‐species flocks in primary and secondary forests. In addition, we show that secondary forest flocks retain a large percentage of the functional diversity exhibited by their primary forest counterparts. Abstract Secondary forest has the potential to

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates
Global Ecology and Biogeography, Volume 32, Issue 1, Page 49-69, January 2023., 2023 Abstract Aim To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser ...
