Lost forever? Ecosystem functional changes occurring after agricultural abandonment and forest recovery in the semiarid Chaco forests
(Elsevier, 2019-02-10)
Semiarid forests are worldwide threatened by land use changes, particularly agriculture. However, in some cases, due to particular economic or social processes, agriculture ends and forests may or may not recover to their ...
Relation between light absorption measured by the quantitative filter technique and attenuation of Chlorella fusca cultures of different cell densities: application to estimate the absolute electron transport rate (ETR)
(Springer, 2016-06)
In order to estimate microalgal carbon assimilation or production of Chlorella fusca cultures based on electron transport rate (ETR) as in vivo chlorophyll a fluorescence, it is necessary to determine the photosynthetic ...
Total and aboveground radiation use efficiency in C3 and C4 grass species influenced by nitrogen and water availability
(Blackwell Publishing, 2015-09)
Absorbed solar radiation and radiation use efficiency (RUE) can be used to estimate net primary productivity of terrestrial ecosystems. In ecosystems dominated by grasses, belowground productivity cannot be neglected in ...
Total and aboveground radiation use efficiency in C3 and C4 grass species influenced by nitrogen and water availability
(Wiley; Japanese Society of Grassland Science, 2015-09)
Absorbed solar radiation and radiation use efficiency (RUE) can be used to estimate net primary productivity of terrestrial ecosystems. In ecosystems dominated by grasses, belowground productivity cannot be neglected in ...
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 ...
Análisis de la dinámica temporal de la eficiencia en el uso de la radiación de tres comunidades de centro sur de Corrientes, Argentina
(Facultad de Agronomía, Universidad de Buenos Aires, 2021)
Los modelos radiativos para estimar la productividad se basan principalmente en tres factores: radiación incidente, fracción de la radiación fotosintéticamente activa absorbida por los tejidos verdes (fAPARg) y eficiencia ...
Relating MODIS vegetation index time-series with structure, light absorption and stem production of fast-growing Eucalyptus plantations
(ELSEVIER SCIENCE BV, 2010)
By allowing the estimation of forest structural and biophysical characteristics at different temporal and spatial scales, remote sensing may contribute to our understanding and monitoring of planted forests. Here, we studied ...
