Species composition, similarity and diversity in three successional stages of a seasonally dry tropical forest
Margaret Kalacska,G.A. Sanchez-Azofeifa,Julio Calvo-Alvarado,Mauricio Quesada,Benoit Rivard,Daniel H. Janzen +5 more
TL;DR: The floristic composition, species diversity, similarity and richness among three stages of forest regeneration, and the influence of past land use and the frequency of anthropogenic disturbances on species composition in a seasonally dry tropical forest in northwestern Costa Rica are described.
Journal ArticleDOI
Need for Integrated Research for a Sustainable Future in Tropical Dry Forests
G. Arturo Sánchez-Azofeifa,Margaret Kalacska,Mauricio Quesada,Julio Calvo-Alvarado,Jafet M. Nassar,Jon Paul Rodríguez +5 more
TL;DR: The lack of conservation effort in tropical dry forests is reflected in the fact that few national parks and biological reserves protect and preserve their natural richness, and there are only a handful of real biological research stations with a mandate to bridge the gap between ecology and conservation biology in these ecosystems as discussed by the authors.
Journal ArticleDOI
Ecological fingerprinting of ecosystem succession: Estimating secondary tropical dry forest structure and diversity using imaging spectroscopy
Margaret Kalacska,G.A. Sanchez-Azofeifa,Benoit Rivard,Terry Caelli,H. Peter White,Julio Calvo-Alvarado +5 more
TL;DR: In this article, the authors evaluated the use of EO-1 Hyperion hyperspectral satellite imagery for mapping structure and floristic diversity in a Neotropical tropical dry forest as a way of assessing a region's ecological fingerprint.
