The Role of Land Use Conversion in Shaping the Land Cover of the Central American Dry Corridor
(2020)
The Central American Dry Corridor (CADC) is a trans-border region characterized by climatic and ecological continuities. It is expected to experience rising aridity and severe hydro-climatic events due to climate change. ...
Ecological carrying capacity for intensive tilapia (Oreochromis niloticus) cage aquaculture in a large hydroelectrical reservoir in Southeastern Brazil
(Elsevier B.V., 2015-05-01)
Cage culture of tilapia (Oreochromis niloticus) in large reservoirs is an emergent aquaculture practice in Brazil. Due to the availability of large amounts of suitable quality waters in hydroelectric dams, there is a large ...
Conversion of D-xylose into furfural with aluminum and hafnium pillared clays as catalyst
The industrial practice used to produce furfural is the dehydration of pentoses, which is carried out using highly corrosive and contaminating mineral acid catalysts. Because of the ecological and toxicological threats of ...
Impacts of forest cover change on ecosystem services in high Andean mountains
(ELSEVIER, 2015-01-01)
Land conversion affects the delivery of ecosystem goods and services. In this study, we used a 50 years time series of land cover maps to assess the potential impacts of forest cover changes on ecosystem services. A ...
Efeito da transposição de galharia sobre a fauna de artrópodes da serapilheira, em uma área de cerrado
(2013-09-01)
The results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood ...
Effect of brushwood transposition on the leaf litter arthropod fauna in a cerrado area
(Sociedade Brasileira de Ciência do Solo, 2013-09-01)
The results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood ...
Floating photovoltaic plants: ecological impacts versus hydropower operation flexibility
(Elsevier, 2020)
Floating photovoltaic power plants are a quickly growing technology in which the solar modules float on water bodies instead of being mounted on the ground. This provides an advantage, especially in regions with limited ...
Ecological processes structuring the ocean microbiome across space and time
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2023-03-09)
The marine microbiome, including prokaryotes and minute unicellular eukaryotes, stands for a great part of biodiversity and is essential for ocean food webs and global biogeochemical cycles. Yet, investigating their diversity ...
Land-use effects on structural and functional composition of benthic and leaf-associated macroinvertebrates in four Andean streams
(2018)
The replacement of native forests by pastures takes place widely in the Andes. The effects of such land-use change on aquatic assemblages are poorly understood. We conducted a comparative analysis of the effects of forest ...
Electrochemical Characterization of Chromate Free Conversion Coatings on Electrogalvanized Steel
