16 maj 2024 · We present a framework for estimating the total energy costs of reproduction by combining data on the energy content of offspring (direct costs) and the metabolic load of bearing them (indirect costs).
Our results highlight the role of cellular costs rather than environmental scarcity in shaping growth, with two key factors: the internal protein cost associated with micronutrient use and the available membrane space for transporters.
At the heart of this subject are two important concepts: 1) all cellular structures have energetic costs composed of different components that should be properly defined and evaluated; and 2) the energetic costs and benefits of these cellular structures can translate into fitness differences that influence long-term evolutionary trajectories.
14 cze 2013 · Metabolic costs are associated with the existence of a particular trait and the energy necessary for the trait's existence, while fitness costs are those that have an impact on the organism's ability to survive and reproduce (1).
27 lip 2021 · We can define life in very different ways depending on the context and the focus we want to give to the definition. For example, we can define life as the period from birth to death or as the condition that occurs only in living organisms.
2 wrz 2017 · Literature features a multitude of terms synonymous to LCC to describe costing across the life cycle of a product, a system or a project, including Through-Life Costing (TLC), Whole-Life Costing (WLC) and Total Cost of Ownership (TCO).
29 sie 2023 · The aim of this research is to carry out a literature review on the use of life-cycle cost (LCC) approaches for hydrogen technologies, by analysing its evolution over a decade (2012–2021).
