An overview of existing and promising technologies for national forest monitoring
(Springer-Verlag France, 2015-09)
The main goal of national forest programs is to lead and steer forest policy development and implementation processes in an inter-sectoral way (FAO 2006). National forest monitoring systems contribute to forest programs ...
Sensibility analysis of the Trace Transform on land coverage images
(Institute of Electrical and Electronics Engineers Inc., 2015)
Aerial or satellital images may be used to produce terrain coverage maps, which in time are a very useful and important tool for decision-making in several fields including biodiversity, telecommunications and natural ...
Environmental gradients and the evolution of successional habitat specialization: a test case with 14 neotropical forest sites
(Blackwell Publishing Ltd, 2015-09)
Successional gradients are ubiquitous in nature, yet few studies have systematically examined the evolutionary origins of taxa that specialize at different successional stages. Here we quantify successional habitat ...
