Metabolic scaling regularity in aquatic ecosystems
(CICIMAR Oceánides, 2012)
We tested the hypothesis that ecosystem metabolism follows a quarter power scaling relation, analogous to organisms. Logarithm of Biomass/Production (B/P) to Trophic Level (TL) relationship was estimated to 98 trophic ...
The metabolic urban network: Urbanisation as hierarchically ordered space of flows
(Elsevier Ltd, 2020-11-26)
Urban ecosystems perform a distinctive metabolism appropriating fundamental materials and energy resources from other ecosystems. This appropriation enables a productive circularity which sustains the material production ...
Drivers of ecosystem metabolism in two managed shallow lakes with different salinity and trophic conditions: The Sauce Grande and La Salada Lakes (Argentina)
(MDPI AG, 2018-08-25)
Understanding the drivers and how they affect ecosystem metabolism is essential for developing effective management policy and plans. In this study, net ecosystem production (NEP), ecosystem respiration (R), and gross ...
Do warming and humic river runoff alter the metabolic balance of lake ecosystems?
(Birkhauser Verlag Ag, 2016-10)
Global warming is expected to influence lake gross primary production (GPP) and ecosystem respiration (R) by increasing water temperature and terrestrial export of organic material and inorganic nutrients from the catchment. ...
Estimation of ecosystem metabolism from diel oxygen technique in a saline shallow lake: La Salada (Argentina)
(Springer, 2014-10)
Studies based on continuous monitoring of diel changes in dissolved oxygen concentration allow the estimation of ecosystem metabolism and provide a measure of the overall trophic processes of an ecosystem. In this study, ...
Analysis of co-regulated abundance of genes associated with arsenic and phosphate metabolism in Andean Microbial Ecosystems
(bioRxiv.org, 2019-12)
Phosphate and arsenate are very similar compounds, and there is great interest in studying their relationship and their interaction with biological systems. Despite having no apparent biological function, specific genes ...
Microbial populations and activities of mangrove, restinga and Atlantic forest soils from Cardoso Island, Brazil
(Wiley-Blackwell, 2014-04-01)
AimMangroves provide a distinctive ecological environment that differentiates them from other ecosystems. This study deal to evaluate the frequency of microbial groups and the metabolic activities of bacteria and fungi ...
