The influence of vegetation cover on the grain-size distributions and thicknesses of two Icelandic tephra layers

open access: yesVolcanica, 2022
Grain-size distributions and thicknesses of tephra layers are used to reconstruct characteristics, dynamics, and hazards of explosive volcanic eruptions, but the extent to which the preservation of tephra is in uenced by depositional environments is ...

Estuarine benthic diversity declines with temperature across a tropical–temperate gradient

open access: yesEcography, EarlyView.
Estuarine benthic sediments are important habitats that support ecosystem health and productivity, but the drivers of large‐scale patterns in benthic diversity are not well documented. Using 18S amplicon sequencing of 425 sediment DNA samples from estuaries spanning 20° of latitude along Australia's east coast, we assessed tropical–temperate patterns ...

Granulometric Analysis on Remote Sensing Images: Application to Mapping Retrospective Changes in the Sahelian Ligneous Cover

open access: yesISPRS International Journal of Geo-Information, 2016
This paper illustrates how the use of mathematical morphology can be a powerful tool for the mapping of ligneous cover in semi-arid lands. Ligneous cover plays a fundamental role in Sahel semi-arid regions since this resource is vital to the resilience ...

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Morphological Residues and a General Framework for Image Filtering and Segmentation

open access: yesEURASIP Journal on Advances in Signal Processing, 2001
Morphological residues represent an image in an hierarchical way by means of a decomposition of its structures and according to a size parameter . From this decomposition, we can obtain a relation between the different residual levels associated with ...

Physical and Chemical Characterization of Soil in Urban Solid Waste Disposal Area

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Waste generation and subsequent disposal in adequate sites still have limitations in some Brazilian municipalities. Therefore, environmental monitoring of these areas is extremely important, as it helps to preserve the environment. The purpose of this study is to analyze the chemical and physical parameters of soil in a landfill area. For this,
