Abstract
The preservation of ecosystems such as mangroves plays a key role in mitigating the negative effects arising from climate change, especially for the capture of atmospheric carbon dioxide, the main agent of degradation of the ozone layer. The remote sensing application studies aim to develop that allows the preservation of ecosystems such as mangroves. This study aims to evaluate the anatomical structure of three species in a mangrove established at Pernambuco State as an aid in understanding the spectral responses shown by these species. Mature leaves of Rhizophora mangle, Laguncularia racemosa and Avicennia schaueriana were collected in the estuary of Maracaípe, in the district of Ipojuca-PE, and cross-sections of leaf lamina and epidermis dissociation were performed, following usual procedures in plant anatomy. Individuals of R. mangle showed the highest values of thickening of the cuticle and epidermis. A. schaueriana detached through the highest values for the thickness of palisade and L. racemosa showed the highest values for the thickening of the spongy parenchyma. The species showed different structural characteristics with different action related to the reflectance, absorptance, and transmittance, allowing the use of remote sensing techniques for proper assessment of vegetation conditions for the preservation of the environment.
Highlights
Climate change is often associated with human activities, and one of the main aspects that contribute to the appearance of these climatic variations is related to changes in natural vegetation covertures, together with the burning of fossil fuels, releasing large quantities of carbon dioxide to the atmosphere (Ayodya, 2003)
Some attempts were made to minimize the negative effects of the accumulation of carbon dioxide in the atmosphere, highlighting the reforestation, including the coastal vegetation (Fonseca & Drummond, 1998)
These authors evaluated the practice of reforestation with native species in areas with mangroves in the Rio de Janeiro State, aiming to reduce the damage caused by the greenhouse effect
Summary
Climate change is often associated with human activities, and one of the main aspects that contribute to the appearance of these climatic variations is related to changes in natural vegetation covertures, together with the burning of fossil fuels, releasing large quantities of carbon dioxide to the atmosphere (Ayodya, 2003).Lucena et al./ Journal of Hyperspectral Remote Sensing 02 (2011) 19-31This ecosystem plays an important role when it is related to carbon sequestration from the atmosphere. Some attempts were made to minimize the negative effects of the accumulation of carbon dioxide in the atmosphere, highlighting the reforestation, including the coastal vegetation (Fonseca & Drummond, 1998). These authors evaluated the practice of reforestation with native species in areas with mangroves in the Rio de Janeiro State, aiming to reduce the damage caused by the greenhouse effect. It is clear the importance of preserving the mangrove ecosystem, since these regions have environmental conditions conducive to the development of several species of fish and crustaceans (Lacerda, 2003). The monitoring of environments such as mangroves is performed efficiently through the use of remote sensing techniques, it is possible to manage and monitor information from the temporal and spatial variables and carry out a preliminary assessment of problems in different areas, using simulations and mathematical models (Petersen et al 1991; Vaiphasa et al, 2005, Wang et al 2004; Giri et al, 2007), the space-time mapping is a way of monitoring
