Assessment of empirical methods for estimation of reference evapotranspiration in the Brazilian Savannah

open access: yesAustralian Journal of Crop Science, 2019
Evapotranspiration can be sufficiently estimated when meteorological data are available to implement robust models such as Penman-Monteith (PM). However, due to data scarcity, alternative approaches are necessary. In this context, this study aims to compare the reference evapotranspiration (ETo) obtained from the PM standard method with eight empirical

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

open access: yesDevelopmental Dynamics, Volume 255, Issue 6, Page 602-615, June 2026.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Nitrogen and Phosphorus Budget for a Deep Tropical Reservoir of the Brazilian Savannah [PDF]

open access: yesWater, 2019
This research investigated the source and fate of different chemical species of N and P on a deep tropical urban reservoir, the artificial Lake Paranoá, located in the city of Brasilia (Brazil). To determine an N and P budget, nutrient input from the external load (four main tributaries and two wastewater treatment plants), internal load (from sediment)

One Assay to Rule Them All: Development of a Global Environmental DNA Tool to Support Range‐Wide Surveys of an Imperiled Sawfish and Its Application in the Eastern Tropical Pacific

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
To identify promising locations where Largetooth Sawfish, Pristis pristis, may persist, a novel species‐specific Droplet Digital PCR (ddPCR) assay was designed capable of detecting a single copy of DNA, with in silico and in vitro validation experiments indicating functionality across the species' historical range.

COFFEE PRODUCTION IN THE BRAZILIAN SAVANNAH: CONSIDERATIONS ABOUT NITROGEN NUTRITION

open access: yesBRAZILIAN JOURNAL OF AGRICULTURE - Revista de Agricultura, 2020
The Brazilian savannah, locally called “cerrado”, is a forest and shrub type ecosystem that occupied vast areas of very flat relief, mainly distributed in the central part of the country. In the mid 1970ies, this region was recognized as unfertile with little possibility of agricultural use.

Effects of land-use and -cover changes on streamflow regime in the Brazilian Savannah

open access: yesJournal of Hydrology: Regional Studies, 2021
Study region: The study was conducted in the Mortes River Basin (MRB), Mato Grosso State (Brazil), owing to the constant removal of native forest (Brazilian Savannah, popularly known as Cerrado) for agriculture and pasture purposes. Study focus: The hydrological model for large basins (MGB-IPH) was employed to assess the hydrological impacts due to ...

Environmental Policy Without Implementation? A Review of Factors Contributing to Implementation Gaps in Low‐ and Middle‐Income Countries

open access: yesEnvironmental Policy and Governance, Volume 36, Issue 3, Page 611-635, June 2026.
ABSTRACT The sound formation of robust environmental policies is increasingly important for low‐ and middle‐income countries (LMICs) to achieve their national objectives and international commitments. However, policy implementation can be complex, and environmental policies may not be prioritised given other critical socio‐economic development issues ...

Andean grain crop introduction to the Brazilian savannah. [PDF]

open access: yes, 1998
Agricultural history of the Brazilian savannah dates back 150 years, beginning with extensive cattle ranching on native grassland, eventually developing into a rice-pasture system, followed by today’s modern grain production on 10 million ha.
