P.; TANSEY, K.; BALZTER, H. The tropical savanna in Brazil known as the Cerrado covers circa 23% of the Brazilian territory, but only 3% of this area is protected. High rates of deforestation and degradation in the woodland and... ... Repository: BDPA Publication year: 2020
Spondias tuberosa trees grown in tropical, wet environments are more susceptible to drought than those grown in arid environments. Authorship: ANTUNES, W. C.; MENDES, K. R.; CHAVES, A. R. de M.; OMETTO, J. P.; JARMA-OROZCO, A.; POMPELLI, M. F.
