Ecological Aspects in Control of Small-scale Biomass Fired Boilers [PDF]

open access: yesInternational Journal of Energy, 2021
Control of combustion in small-scale boilers has been standing outside interest for a long time. More attention has been paid to design of the boilers than to economic and ecological aspects of their operation. To the question under which operating conditions of the boiler a controller carries out its activities has been paid a limited attention.

Roadmap Towards a Bioenergy Model of Life Cycle Sustainability Assessment

open access: yesBulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2021
The emergent life cycle assessment (LCA) methodology, techniques and models were punctuated by divergences concerning the system expansion, allocation rules and causation modeling.

Drought effect on plant biomass allocation: A meta‐analysis

open access: yesEcology and Evolution, 2017
Drought is one of the abiotic stresses controlling plant function and ecological stability. In the context of climate change, drought is predicted to occur more frequently in the future. Despite numerous attempts to clarify the overall effects of drought

Digital Biomass Accumulation Using High-Throughput Plant Phenotype Data Analysis

open access: yesJournal of Integrative Bioinformatics, 2017
Biomass is an important phenotypic trait in functional ecology and growth analysis. The typical methods for measuring biomass are destructive, and they require numerous individuals to be cultivated for repeated measurements.

Identifying conversion efficiency as a key mechanism underlying food webs evolution : a step forward, or backward ? [PDF]

open access: yesOikos, Nordic Ecological Society, 2021, 130 (6), pp.904-930, 2019
Body size or mass is one of the main factors underlying food webs structure. A large number of evolutionary models have shown that indeed, the adaptive evolution of body size (or mass) can give rise to hierarchically organised trophic levels with complex between and within trophic interactions.

Ecological Insights into the Dynamics of Plant Biomass-Degrading Microbial Consortia [PDF]

open access: yesTrends in Microbiology, 2017
Plant biomass (PB) is an important resource for biofuel production. However, the frequent lack of efficiency of PB saccharification is still an industrial bottleneck. The use of enzyme cocktails produced from PB-degrading microbial consortia (PB-dmc) is a promising approach to optimize this process.

A theory of pulse dynamics and disturbance in ecology

open access: yesEcology, 2019
We propose four postulates as the minimum set of logical propositions necessary for a theory of pulse dynamics and disturbance in ecosystems: (1) resource dynamics characterizes the magnitude, rate, and duration of resource change caused by pulse events,
