Hydrogen production by biogas steam reforming: A technical, economic and ecological analysis
Fuel cells are electrochemical energy conversion devices that convert fuel and oxidant electrochemically into electrical energy, water and heat. Compared to traditional electricity generation technologies that use combustion ...
Feeding and foraging behaviour of alpaca in northern Chile
Alpaca play a primary role in the Andean peasant economy. Major constraints to productivity include lack of knowledge of relations between reproduction and nutrition and of the potential of alpaca outside their normal ...
A reference business process for ecological niche modelling
(ELSEVIER SCIENCE BV, 2008)
Ecological niche modelling combines species occurrence points with environmental raster layers in order to obtain models for describing the probabilistic distribution of species. The process to generate an ecological niche ...
Optimization of an irreversible Otto and Diesel cycles based on ecological function
In this work, a mathematical model is presented for the irreversible Otto and Diesel cycles using finite time thermodynamics. The cycle is analyzed between two reservoirs with infinite thermal capacitances, where the ...
Rewilding ecological communities and rewiring ecological networks
Rewilding encompasses management actions such as reintroductions and translocations with the purpose of restoring ecological processes and ecosystem functions that were lost when species were locally extirpated. The success ...
Three levels of integrating ecology with the conservation of South American temperate forests: The initiative of the Institute of Ecological Research Chiloe, Chile
The diversity of native species assemblages and that of indigenous cultures that once characterized the temperate forests of southern Chile have experienced a process of homogenization ever since the Spanish conquest. Today ...
Reconstructing past ecological networks: the reconfiguration of seed-dispersal interactions after megafaunal extinction
The late Quaternary megafaunal extinction impacted ecological communities worldwide, and affected key ecological processes such as seed dispersal. The traits of several species of large-seeded plants are thought to have ...
Long-term ecological research in the forests of the United States: Key lessons for its application in Chile and around the world
