Identifying Dicymbe corymbosa Monodominant Forests in Guyana Using Satellite Imagery
TL;DR: In this paper, the suitability of Landsat satellite imagery for mapping regional distribution of Dicymbe corymbosa forests in Guyana's Upper Potaro River Basin was assessed.

Adult mortality in a low-density tree population using high-resolution remote sensing.
TL;DR: The proof-of-concept study shows that one can remotely estimate adult mortality rates for canopy tree species precisely in the presence of variable detection and missing observations.

Mesoscale assessment of changes in tropical tree species richness across a bioclimatic gradient in Panama using airborne imaging spectroscopy
Ben Somers,Ben Somers,Gregory P. Asner,Roberta E. Martin,Christopher B. Anderson,David E. Knapp,S. Joseph Wright,Ruben Van De Kerchove +7 more
TL;DR: In this paper, a top-down mesoscale analysis of tropical tree species richness across a bioclimatic gradient in Panama was performed using imaging spectroscopy, which revealed significant spectral changes along the precipitation gradient and indicated that niche differentiation with respect to soil water availability is a direct determinant of both local and regional-scale distributions of tropical trees.

Mapping invasive species and spectral mixture relationships with neotropical woody formations in southeastern Brazil
Cibele Hummel do Amaral,Dar A. Roberts,Teodoro Isnard Ribeiro de Almeida,Carlos Roberto de Souza Filho +3 more
TL;DR: In this article, the performance of a Multiple Endmember Spectral Mixture Analysis (MESMA) applied to imaging spectroscopy data for mapping Dendrocalamus sp. (bamboo) and Pinus elliottii L. (slash pine) in a Brazilian neotropical landscape within the tropical Brazilian savanna biome was evaluated.

Pattern classification and scene analysis
Richard O. Duda,Peter E. Hart +1 more
TL;DR: In this article, a unified, comprehensive and up-to-date treatment of both statistical and descriptive methods for pattern recognition is provided, including Bayesian decision theory, supervised and unsupervised learning, nonparametric techniques, discriminant analysis, clustering, preprosessing of pictorial data, spatial filtering, shape description techniques, perspective transformations, projective invariants, linguistic procedures, and artificial intelligence techniques for scene analysis.

A new method for non-parametric multivariate analysis of variance
TL;DR: In this article, a non-parametric method for multivariate analysis of variance, based on sums of squared distances, is proposed. But it is not suitable for most ecological multivariate data sets.

TL;DR: Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.
