Comparing tree shapes: beyond symmetry
(Wiley Blackwell Publishing, Inc, 2017-09)
This paper describes two types of problems related to tree shapes, as well as algorithms that can be used to solve these problems. The first problem is that of comparing the similarity of the unlabelled shapes instead of ...
Elaboração de mapas de dispersão de jabuticabeiras nativas em fragmentos florestais do sudoeste do Paraná
(Universidade Tecnológica Federal do ParanáDois VizinhosBrasilEngenharia FlorestalUTFPR, 2014-02-04)
Forest fragmentation reduces the size of the breeding population and the population density of plant species, which can compromise their development and survival. In southwestern Paraná region were observed 14 forest ...
The effect of spectral and spatial degradation of hyperspectral imagery for the Sclerophyll tree species classification
(CIENCIAS, 2013)
Hyperspectral imaging can be a useful remote-sensing technology for classifying tree species. Prior to the image classification stage, effective mapping endeavours must first identify the optimal spectral and spatial ...
A new tree species of Schinopsis (Anacardiaceae) from Paraguay and Bolivia
(Magnolia Press, 2014-08)
The new tree species Schinopsis boqueronensis, endemic to the Bolivian-Paraguayan Chaco, is described, illustrated and compared to the related Schinopsis heterophylla. A distribution map and photographs of the new species ...
A Regional Red List of Montane Tree Species of the Tropical Andes: Trees at the top of the world
(Botanic Gardens Conservation International, 2014)
Andean montane forests are a major global conservation priority owing to their biological richness and high level of species endemism. Botanically the Andes are very rich in species but they remain relatively unstudied. ...
Comparison of pixel and region-based approaches for tree species mapping in atlantic forest using hyperspectral images acquired by uav
(2019-06-04)
The objective of this work was the comparison of two different classification approaches to detect four different tree species of a highly diverse tropical Atlantic Forest area. In order to achieve the objective, images ...
Megafauna extinction, tree species range reduction, and carbon storage in Amazonian forests
(2016-02-01)
During the Late Pleistocene and early Holocene 59 species of South American megafauna went extinct. Their extinction potentially triggered population declines of large-seeded tree species dispersed by the large-bodied ...
