13. A snapshot of the limnological features in tropical floodplain lakes: the relative influence of climate and land use
Resumo Objetivo O objetivo desse estudo foi investigar a influência relativa do clima (temperatura e precipitação) e do uso da terra nas características limnológicas de 30 lagoas da planície de inundação do Rio Araguaia, no Brasil Central, um importante rio que drena no Cerrado brasileiro. Métodos As lagoas foram amostradas em um mesmo período,

14. Indirect quantitative-qualitative pedologic geomorphic characterization in sub-basin of 7th order of the middle São Francisco watershed - northern Minas Gerais state
Abstract The characterization presented in this study aims to identify and map the different types of pedogeomorphic units found in a 7th order, the Pandeiros river basin, in the upper São Francisco River (1st order basin), located in the North of Minas Gerais State. A general panoramic view of the geodiversity is presented, since the Pedogeomorphic Maps al

15. Landscape Ecology in a Watershed of the Ocoy River, Western Parana State, Brazil
ABSTRACT This study evaluated the landscape structure of a watershed located in a region considered strategic for the implementation of the Paraná River Biodiversity Corridor. Based on land-use/land-cover mapping, four different scenarios were generated: 1) real situation, 2) considering the edge effect, 3) without Permanent Preservation Areas (APPs), and

16. SPATIAL DYNAMICS OF SEMIDECIDUOUS SEASONAL FORESTS: CASE STUDY IN THE TURVO SUJO RIVER BASIN IN SOUTHEASTERN BRAZIL, BETWEEN THE YEARS OF 2003 AND 2016
RESUMO De acordo com a Agência Nacional das Águas (ANA), a escassez de água vem sendo um problema brasileiro desde 2012 e está diretamente relacionado com a conservação das bacias hidrográficas. É possível monitorar as mudanças da paisagem e conservação dessas bacias com imagens provenientes de sensores orbitais. O trabalho teve como objetivo ana

17. Does the landscape surrounding streams affect the occurrence of freshwater crabs? A case study of the genus Aegla (Crustacea: Decapoda: Anomura) in subtropical basins
ABSTRACT Changes in the landscape where watersheds are located may affect the stream biota in different ways. In order to explore this idea, we collected freshwater crabs of the genus Aegla Leach, 1820 in subtropical region of southern Brazil. We also measured a number of landscape features and physico-chemical variables in the collection streams and surroun

18. Prediction of Topsoil Texture Through Regression Trees and Multiple Linear Regressions
ABSTRACT: Users of soil survey products are mostly interested in understanding how soil properties vary in space and time. The aim of digital soil mapping (DSM) is to represent the spatial variability of soil properties quantitatively to support decision-making. The goal of this study is to evaluate DSM techniques (Regression Trees - RT and Multiple Linear R

19. Knowledge-based digital soil mapping for predicting soil properties in two representative watersheds
ABSTRACT: The estimation of soil physical and chemical properties at non-sampled areas is valuable information for land management, sustainability and water yield. This work aimed to model and map soil physical-chemical properties by means of knowledge-based digital soil mapping approach as a study case in two watersheds representative of different physiogra

20. Hydropedology of a High Tableland with Cerrado, Brazilian Central Plateau: the Frutal Catchment Case Study
ABSTRACT: Currently, the Brazilian savanna (Cerrado) represents the main agricultural area of the country, comprising a great variety of landscapes and soils, geological formations and vegetation patterns, as well as the major watershed. We studied the hydropedology and morphometry of a representative catchment (Frutal river), on a high tableland (Chapada) i

21. Soils Developed on Geomorphic Surfaces in the Mountain Region of the State of Rio de Janeiro
ABSTRACT: The evaluation of soils in representative landscapes constitutes an opportunity to evaluate spatial distribution, discuss formation processes, and apply this knowledge to land use and management. In this sense, from the perspective of an environmentally diversified region, the aim of the present study is to evaluate the occurrence and understand th

22. Analysis of Potential for Linear Erosion in the Cerrado Biome Using Morphopedology
ABSTRACT The Cerrado is a vegetation complex with a wide variety of phytophysiognomies, and sustainable management is essential for maintaining biodiversity. Morphopedology is a tool that can assist in developing plans for control of soil and land use, especially in evaluating the potential of soil erosion processes. This technique allows landscape units con

23. Ethnopedology of a Quilombola Community in Minas Gerais: Soils, Landscape, and Land Evaluation
ABSTRACT Quilombolas are Afro-brazilian rural peasants who descended from escaped slaves who tried to carve out territories of autonomy (called Quilombos) by collective organization and resistance. Despite many anthropological and ethnopedological studies, little research has been carried out to identify the agricultural practices and the knowledge of people

24. Characterization and Classification of Soils under Forest and Pasture in an Agroextractivist Project in Eastern Amazonia
ABSTRACT: Knowledge of soils in the Amazon rainforest is becoming increasingly essential due to dynamics adopted by farmers that substitute forest for pastures, together with growing pressure from diverse segments of society towards adoption of sustainable production systems. The objective of this study was to characterize the soils along two toposequences,
