Antibiotic resistance genes as landscape anthropization indicators: Using a wild felid as sentinel in Chile
(Elsevier, 2020)
Antimicrobial resistance is a global emerging public health issue whose presence and impact in wildlife are widely unknown. Antimicrobial resistance genes (ARGs) are considered environmental contaminants, suitable to ...
Approach to assess agroecosystem anthropic disturbance: Statistical monitoring based on earthworm populations and edaphic properties
(Elsevier Science, 2020-04)
Land degradation due to anthropic factors is the reduction of its actual or potential productivity. Nowadays, this topic is a major concern, as it affects more than one third of the soil in the world. This work presents ...
An Ethnoarchaeological Study on Anthropic Markers from a Shell-midden in Tierra del Fuego (Southern Argentina): Lanashuaia II
(Taylor & Francis, 2017-10)
For many years the identification of activity areas has been carried out through the spatial distribution of lithics, zooarchaeological remains and specific features such as fireplaces. However, these data are rarely ...
Anthropic Exposure Indicator for River Basins Based on Landscape Characterization and Fuzzy Inference
(2021-01-01)
Abstract: The objective of this study is to develop an anthropic exposure indicator for river basins using quantitative and qualitative aspects of the landscape and morphometric analysis based on fuzzy logic and geoprocessing. ...
Heavy metals accumulation in the subterranean rodent Ctenomys talarum (Rodentia: Ctenomyidae) from areas with different risk of contamination
(Inst Vertebrate Biology As Cr, 2010-07)
The objective of this work was to determine the concentrations of four heavy metals (Pb, Zn, Fe and Cu) in muscle and liver from the solitary subterranean rodent Ctenomys talarum from natural dunes, cultivated area and ...
Coastline changes and sedimentation related with the opening of an artificial channel: The Valo Grande Delta, SE Brazil
(Faculdad de la Republic(UDELAR). Faculdad de cienciasPunta del Este, 2013-10)
The role played by human activity in coastline changes indicates a general tendency of retreating coasts, especially deltaic environments, as a result of the recent trend of sea level rise as well as the blockage of the ...

(2020-02-10)
Antimicrobial resistance is a global emerging public health issue whose presence and impact in wildlife are widely unknown. Antimicrobial resistance genes (ARGs) are considered environmental contaminants, suitable to ...
Factors that control the spatial and temporal distributions of phosphorus, nitrogen, and carbon in the sediments of a tropical reservoir
(2018-01-01)
The impacts of anthropic activities have had profound effects on the nitrogen (N) and phosphorus (P) cycles in many aquatic ecosystems. We investigated the spatial and temporal distributions of carbon (C), N, and P in the ...
Determinacąõ da Pressaõ Ambiental que o Uso da Terra Exerce sobre os Recursos Hídricos na Bacia Hidrográfica do Rio Juqueri, no Município de Mairiporã, Estado de Saõ Paulo, Brazil
(2017-09-01)
The objective of this study was to determine the relationship between land use and water quality, through canonical correlations between the WQI parameters and the changes in the last 30 years, using LANDSAT 5, 7 and 8 ...
Multi-temporal analysis of land use land cover interference in environmental fragility in a Mesozoic basin, southeastern Brazil
(Elsevier B.V., 2021-02-01)
Changes in land use land cover without proper planning cause several adverse environmental impacts on hydrographic basins. Mapping these dynamics is a key tool to understand the rapid changes in landscapes that directly ...
