Mauricio Castillo-Núñez,G. Arturo Sánchez-Azofeifa,Arie Croitoru,Benoit Rivard,Julio Calvo-Alvarado,Ralph Dubayah +5 more
TL;DR: In this paper, a waveform LiDAR system was used to detect the location of wind-dispersed or vertebrate dispersed forest patches in a mosaic of a secondary tropical dry forest in the Santa Rosa National Park, Costa Rica.
Journal ArticleDOI
Discrimination of liana and tree leaves from a Neotropical Dry Forest using visible-near infrared and longwave infrared reflectance spectra
TL;DR: In this article, the use of longwave infrared reflectance (LWIR, 8-11μm) as a wavelength region for the classification of liana and tree leaves and compare classification results with those obtained using VIS-NIR, 0.45-0.95
Journal ArticleDOI
Global warming and amphibian losses; The proximate cause of frog declines? (Reply)
J. Alan Pounds,Martín R. Bustamante,Luis A. Coloma,Jamie A. Consuegra,Michael P. L. Fogden,Pru N Foster,Enrique La Marca,Karen L. Masters,Andrés Merino-Viteri,Robert Puschendorf,Santiago R. Ron,Santiago R. Ron,G. Arturo Sánchez-Azofeifa,Christopher J. Still,Bruce E. Young +14 more
TL;DR: Here it is shown why the working model underlying the test for a link between global warming and amphibian disappearances was appropriate and the complexity of the imminent threat to species survival that results as global warming conspires with various other agents is highlighted.
Journal ArticleDOI
Water Resources and Regional Land Cover Change in Costa Rica: Impacts and Economics
TL;DR: In this article, the relationship between sediment production and the deterioration of land resources in Costa Rica is less understood than expected, and that new sediment monitoring systems must be implemented in order to be able to detect the overall impact of tropical deforestation and habitat fragmentation on sediment production.
