Effect of Forward/Inverse Model Asymmetries Over Retrieved Soil Moisture Assessed With an OSSE for the Aquarius/SAC-D Mission
(Institute Of Electrical And Electronics Engineers, 2014-03)
An Observing System Simulation Experiment (OSSE) for the Aquarius/SAC-D mission that includes different models for forward and retrieval processes is presented. This OSSE is implemented to study the errors related to the ...
Re-absorption and scattering of chlorophyll fluorescence in canopies: A revised approach
(Elsevier Science Inc., 2020-09)
The measurement of chlorophyll fluorescence in remote way represents a tool that is becoming increasingly important in relation to the diagnosis of plant health and carbon budget on the planet. However, the detection of ...
Aboveground vegetation and perennial grass seed bank in arid rangelands disturbed by grazing
(Elsevier, 2015)
Recruitment by seeds can be an important mechanism for recovery of plant communities following disturbance. Our objective was to assess the density and spatial patterning of perennial grass (highly preferred by herbivores) ...
Canopy active fluorescence spectrum tracks ANPP changes upon irrigation treatments in soybean crop
(Elsevier Science Inc., 2021-09)
Accurate estimation of aerial net primary production (ANPP) using remotely acquired data is one of the main challenges in both environmental monitoring and precision agriculture. Reflectance-based techniques have been ...
Scattered Trees in a pasture matrix enhance Phosphate deposition in the soil via rainfall redistribution: role of structural and morphological traits

Avaliação dos efeitos topográficos e direcionais sobre os índices de vegetação na definição de zonas de manejo em povoamentos de pinus no sul do Brasil
(Universidade Federal de Santa MariaBrasilGeografiaUFSMPrograma de Pós-Graduação em GeografiaCentro de Ciências Naturais e Exatas, 2021-08-25)
The application of remote sensing data represents an alternative for monitoring forest stands. However, in most applications, the sources of radiometric uncertainty associated with the data are not considered. This study ...

Extensive pollen flow in a natural fragmented population of Patagonian cypress Austrocedrus chilensis
(Springer, 2014-12)
Habitat fragmentation might significantly affect mating and pollen dispersal patterns in plant populations, contributing to the decline of remnant populations. However, wind-pollinated species are able to disperse pollen ...
Characterisation of functional-trait dynamics at high spatial resolution in a Mediterranean forest from sentinel-2 and ground-truth data
(MDPI, 2018-12)
The characterisation of functional-trait dynamics of vegetation from remotely sensed data complements the structural characterisation of ecosystems. In this study we characterised for the first time the spatial heterogeneity ...
A continuous record of vegetation, fire-regime and climatic changes in northwestern Patagonia spanning the last 25,000 years
(2018)
We present a high-resolution precisely dated terrestrial paleovegetation/paleoclimate record from Lago Pichilaguna, northwestern Patagonia (40 degrees-44 degrees S), which spans continuously from the Last Glacial Maximum ...
