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) ...
Feedbacks between vegetation and disturbance processes promote long-term persistence of forest-grassland mosaics in south Brazil
(Elsevier B.V., 2014-11-10)
Vegetation changes, such as shrub encroachment and forest expansion over grasslands, prairies and savannas have been related to changes in climatic (mainly rainfall and temperature) and atmospheric conditions (CO2 ...
Spatial variability and intensity frequency of surface heat island in a Brazilian city with continental tropical climate through remote sensing
(2018-01-01)
Tropical cities located in inland Brazil typically have high temperatures that are extremely uncomfortable and detrimental to their population's health. This article analyzes the spatial variability of target temperatures, ...
Spatial and temporal variability of vegetation cover in the moxotó watershed, Pernambuco, Brasil Variabilidad espacial y temporal de la cobertura vegetal de los años 1984 a 2011 en la cuenca hidrográfica del Río Moxotó, Pernambuco, Brasil
(Universidad de Tarapaca, 2019)
The Caatinga vegetation is predominant in the Moxotó basin hidrology. This type of vegetation has been cleared at an accelerated rate, mainly due to the consumption of native wood, exploited for domestic industrial and ...
