Abstract Forest expansion has been observed in China over the past decades, but typically applied coarse resolution satellite data does not reveal spatial details about China’s forest transition. By using three decades of observations at a 30-m resolution, we here complex spatiotemporal patterns individual stands forming return history southern China. We calculate age, densification rates, and ...
The current trend of declining epiphytic richness caused by human activities (forest fragmentation, logging , agriculture, and livestock grazing) and the greater efforts required to sample and identify the most inconspicuous species have necessitated the use of indicators of the species richness. In this study, we examined the potential of predicting epiphytic lichen richness based on the richn...
Kelp forests are productive coastal ecosystems that provide a range of ecosystem services. Mapping the distribution and area occupied by kelp is critical step to identify their functions services, including role in carbon cycle, detect changes distribution. We compiled quantitative data dominant genera Laminaria Saccharina across Nordic region, allowing us separate (areas with dense or moderate...
Dry tropical forests undergo massive conversion and degradation processes. This also holds true for the extensive Miombo forests that cover large parts of Southern Africa. While the largest proportional area can be found in Angola, the country still struggles with food shortages, insufficient medical and educational supplies, as well as the ongoing reconstruction of infrastructure after 27 year...
Identification and monitoring of surface water using remote sensing have become very important in recent decades due to its importance in human needs and political decisions. Therefore, surface water has been studied using remote sensing systems and Sentinel-1 and Sentinel-2 sensors in this study. In this paper, two data fusion approaches and decision fusion improve the accuracy of surface wate...
3 of 201 Characterization of Composites with Aligned Carbon Nanotubes (CNTs) as Reinforcement by Enrique J. García Submitted to the Department of Aeronautics and Astronautics in partial fulfillment of the requirements for the degree of Master of Science in Aeronautics and Astronautics Abstract Carbon nanotubes’ (CNTs) superlative combination of electrical, thermal, and especially mechanical pro...
Abstract Aim Ecological theory and empirical evidence indicate that greater structural complexity diversity in plant communities increases arthropod abundance diversity. Nonnative plants are typically associated with low due to lack of evolutionary history. However, nonnative increase the forests, as is common urban forests. Therefore, forests ideal ecosystems determine whether will arthropods,...
