Not only exotic grasslands: The scattered trees in cultivated pastures of the Brazilian Cerrado
(Elsevier B.V., 2021-07-01)
Cultivated pastures occupy 30% of the Brazilian Cerrado. Most pastures have low productivity, demanding intensification. Pasture intensification, as conventionally proposed, promises conservation by land sparing. However, ...
Pattern recognition in trunk images based on co-occurrence descriptors: a proposal applied to tree species identification
(Ieee, 2015-01-01)
Tree species identification is required for many applications. However, current techniques are dependent on the presence of morphological structures such as leaves, which restricts its use in certain situations and seasons. ...

Evaluation of hyperspectral multitemporal information to improve tree species identification in the highly diverse atlantic forest
(2020-01-01)
The monitoring of forest resources is crucial for their sustainable management, and tree species identification is one of the fundamental tasks in this process. Unmanned aerial vehicles (UAVs) and miniaturized lightweight ...
Pollen Dispersal Between Isolated Trees in the Brazilian Savannah: A Case Study of the Neotropical Tree Hymenaea stigonocarpa
(Wiley-Blackwell, 2011-03-01)
This case study examines the pollen dispersal distance, pollen dispersal patterns and intra-family genetic structure for isolated trees in pastures of the bat-pollinated Neotropical tree species Hymenaea stigonocarpa using ...
Gene and species trees of a Neotropical group of treefrogs: Genetic diversification in the Brazilian Atlantic Forest and the origin of a polyploid species
(Academic Press Inc. Elsevier B.V., 2010-12-01)
The Neotropical Phyllomedusa burmeisteri treefrog group includes four diploid (P. bahiana, P. burmeisteri, P. distincta and P. iheringii) and one tetraploid (P. tetraploidea) forms. Here we use mitochondrial and nuclear ...

Spectral Differences of Tree Species Belonging to Atlantic Forest Obtained from Uav Hyperspectral Images
(2020-03-01)
The objective of this study is to evaluate the spectral difference between and within 11 tree species belonging to Brazilian Atlantic Forest located in the countryside of São Paulo State, Brazil. Tree species with different ...
