The renewable and non-renewable exergy and CO2 costs of petroleum derived fuels produced in Brazil are evaluated using exergoeconomy to rationally distribute the exergy costs and the CO2 emitted in processes with more than one product. An iterative procedu ...
Assessing the impacts of climate change on mountain ecosystems is challenging as it takes several decades to observe an ecological response. Using a transplantation experiment in the Swiss Jura Mountains we study the adaptability of beech and spruce to sim ...
Forecasts about 'peak oil', the limits of oil production, are the subject of controversies. 'Peak oil' forecasts are based on extrapolations of a priori chosen mathematical models fitted to field data. Scientifically that is not very sound. To clarify this ...
Biological dispersal shapes species' distribution and affects their coexistence. The spread of organisms governs the dynamics of invasive species, the spread of pathogens, and the shifts in species ranges due to climate or environmental change. Despite its ...
An exergy and environmental comparison between the fuel production routes for Brazilian transportation sector, including fossil fuels (natural gas, oil-derived products and hydrogen), biofuels (ethanol and biodiesel) and electricity is performed, and the p ...
The average unit exergy cost and CO2 emissions of the electricity generated in Brazil are evaluated using the national electricity mix and considering the representative profiles of the electricity generation routes. The Brazilian installed capacity is com ...
Water demand for hydropower production is increasing together with the consciousness of the importance of riparian ecosystems and biodiversity. Some Cantons in Switzerland and other alpine regions in Austria and in Süd Tiröl (Italy) started replacing the i ...
In this paper we compare 10 established frameworks for analyzing social-ecological systems. We limited ourselves to frameworks that were explicitly designed to be used by a wider community of researchers and practitioners. Although all these frameworks see ...
We propose a theoretical river modeling framework for generating variable flow patterns in diverted-streams (i.e., no reservoir). Using a simple economic model and the principle of equal marginal utility in an inverse fashion we first quantify the benefit ...
Cross-diffusion driven instabilities have gained a considerable attention in the field of population dynamics, mainly due to their ability to predict some important features in the study of spatial distribution of species in ecological systems. This paper ...
