Forest cover change analysis based on temporal gradients of the vertical structure and density
(2021-07-01)
Canopy height is an important attribute that allows characterizing the forest vertical structure and analyze changes in vegetation cover over time. The objective of this study is to develop an approach for a spatio-temporal ...
Successional stages and their evolution in tropical forests using multi-temporal photogrammetric surface models and superpixels
(2018-12-01)
Airborne photogrammetric image archives offer interesting possibilities for multi-temporal analyses of environmental evolution. The objective of this investigation was to develop a technique for classifying forest successional ...
Forest destructuring as revealed by the temporal dynamics of fundamental species - Case study of Santa Genebra Forest in Brazil
(Elsevier B.V., 2014-02-01)
Variation in the composition of the tree population is common throughout the history of a well-preserved forest community, with this natural process maintaining the forest structure and giving rise to ecological processes ...
Temporal changes in forest contexts at multiple extents: Three decades of fragmentation in the Gran Chaco (1979-2010), Central Argentina
(Public Library of Science, 2015-12)
The context in which a forest exists strongly influences its function and sustainability. Unveiling the multi-scale nature of forest fragmentation context is crucial to understand how human activities affect the spatial ...
Cover and land use changes in the dry forest of Tumbes (Peru) using sentinel-2 and google earth engine data
(MDPIPE, 2022-10-21)
Dry forests are home to large amounts of biodiversity, are providers of ecosystem services, and control the advance of deserts. However, globally, these ecosystems are being threatened by various factors such as climate ...
Efficiency of protected areas in Amazon and Atlantic Forest conservation: A spatio-temporal view
(2018-02-01)
The Amazon and Atlantic Forest are considered the world's most biodiverse biomes. Human and climate change impacts are the principal drivers of species loss in both biomes, more severely in the Atlantic Forest. In response ...
Analyzing Spatio-temporal Land Cover Dynamics in an Atlantic Forest Portion Using Unsupervised Change Detection Techniques
(2021-01-01)
Over the past decades, the Southeast Atlantic Forest in Paraíba do Sul River Valley has suffered intense deforestation and human disturbances. Due to the Atlantic Forest biodiversity and the economic relevance of such a ...
Changes in forest structure and tree recruitment in Argentinean Chaco: Effects of fragment size and landscape forest cover
(Elsevier Science, 2013-05)
Subtropical Argentinean Chaco forests have been severely deforested and fragmented due to agriculture during the last six decades. The most affected forests are located in areas that are most favorable for crops. This ...
